High pressure water jet cutting to pay attention to what matters?

The main safety technical problems of high-pressure water jet cutting is to prevent high-pressure water jet and splashing water droplets impact, noise and electric shock.

1, Noise and prevention

When the high-pressure water jet machining, water jet flow rate of up to 100 ~ 600m/s, which will produce a lot of noise in the air.

2, Hazards and prevention of high-pressure water jet on the human body

High pressure water jet has great impact, direct injection into the human body will cause great harm. Even if the water jet is used for flushing or stripping process, about 25MPa pressure water jet can penetrate the human body; and the water pressure used for cutting up to 196 ~ 294MPa, such a high-pressure water jets can easily cut off human bone. In addition, if the recoil scattering drops of water injected into the eye, but also make eye damage. Therefore, we must prevent high-pressure water jet sprayed onto the body, you can take the following safety measures:

1, The operator should wear protective glasses at least, it is best to wear a protective mask.

2, To check or replace the cutting nozzle, the pressure of the high-pressure water must be released to the safety level, otherwise the operation can not be performed, in order to avoid accidents.

3, In the surrounding area of high pressure water jet cutting should be set up isolation screen to prevent in the process of human suffering water jet ejected and scattering drops shock effect.

Today the technology development of waterjet cutting machines

On the development of technology today, CNC waterjet cutting technology in the country has been very mature, CNC waterjet cutting machine technology in recent increase gradually, the understanding and application of waterjet cutting machine is also gradually deepening, we all know some other cutting easily produce large metal dust, smelly gas, glare, some cutting incidental questions for customers have a headache, in order to solve this problem, the advantages of waterjet cutting machine is manifested.

For example, waterjet cutting machine in some aspects is better than laser:

1, No limit of cutting thickness

2, Maintenance is not so professional as laser equipment and low degree of difficulty

3, Like brass, aluminum and other reflective materials can be cut

4, Can be easy to install more cutting head to increase production capacity

5, Without input energy, so it will not burn or produce thermal effects

6, You can have a complete set of waterjet cutting equipment for 1/2 to 1/3 of the price of a laser equipment.

7, When you change the cutting materials, you only need to change is the cutting; without have to change the gas, focus or other objects

Waterjet cutting machine working principle is that the water can remove dust, there is a lifting of the cutting platform for work. Due to the water factors will affect the cutting speed, cutting ability, surface finish so the operation still has certain requirements, cutting the same thickness of the steel plate, the energy consumption is lower than other cutting methods, manufacturing costs are relatively low.

In addition, waterjet cutting must be equipped with anti-collision devices or water pressure automatic adjustment device, when water jet cutting, due to the cutting water impact of material surface, the eye in short time is very difficult to determine the position of the cutting nozzle and the height of the distance from the cutting material, in the cutting process, the distortional steel plate if changes might collide with the nozzle, causing breakage or damage to the waterjet nozzle, when cutting, cutting head from the plate to a height of 3-5mm. The most obvious and biggest waterjet cutting features are: the use of wide-body enhancement of beam box structure, beautiful appearance. End frame with low center of gravity structure, symmetrical structure, good stability, ensure the overall rigidity strength and good dynamic equilibrium.

Waterjet cutting technology advantages in the field of cutting

Waterjet cutting device has its own unique advantages, so waterjet technology is recognized worldwide as the most common and the fastest growing technology. Compared to other cutting technologies, the waterjet does not produce toxic or harmful gases or liquids, and do not produce toxic or harmful substances or steam. After waterjet machining, in workpiece surface will not produce heat reaction zone or mechanical stress remains. Waterjet is indeed a universal, high capacity cold cutting technology. We come to you to talk about waterjet cutting machine advantages in cutting processing.

In order to reduce production costs, engineering and manufacturing departments are always looking for superior cutting method. Waterjet technology endowed with many unique features and advantages, can be very effective in reducing costs.

Waterjet divided into non-abrasive waterjet and abrasive waterjet two kinds

No abrasive waterjet

No abrasive waterjet is a way to use water directly cutting, no abrasive waterjet started to be commercially applied to cut corrugated cardboard. No abrasive waterjet be applied to cutting disposable diapers, tissue paper, and automotive interiors by a large number of users. When cutting the tissue paper or paper diapers, no abrasive waterjet operations generated a small amount of water vapor is much less than the steam caused by human contact or breathing. For general non-waterjet cutting process accidental downtime to the tissue paper or paper diapers producer caused a lot of economic losses. The water jet device can provide the above industrial applications throughout the day, the week, the year of the safe use.

Abrasive waterjet

No abrasive waterjet can be used cutting only some of the soft materials, but for steel, iron, stone and other hard materials, non-abrasive waterjet can not be cut or cutting speed extremely slow. If adding an appropriate amount of abrasive in water arrows can be used to cut almost all hard and soft materials.

Abrasive waterjet and non abrasive waterjet exist some differences, no abrasive waterjet use water jet etching material, and abrasive waterjet use sand jet accelerated by water jet, accelerated sand jet to etch the material, abrasive waterjet energy is thousands of times of no abrasive waterjet. Of course, no abrasive waterjet and abrasive waterjet have their respective applications areas. No abrasive waterjet can cut soft materials, abrasive waterjet can cut hard materials.

Waterjet and waterjet cutting technology detailed analysis

Waterjet because of the need to use a powerful pressure, so water jet diameter is very small, so as to produce strong pressure. Water jet is through ultra high pressure generator pressure water to 300MPa or more, spray through a fine nozzle made of advanced carbide, sapphire, diamond or others, its speed is several times of the sound speed, this high pressure water flow with a strong cutting ability, but also by adding sand and other abrasives which can make the cutting ability of several fold enhancement.

High-pressure water jet can cut almost all materials quickly: glass, rubber, fibers, fabrics, steel, stone, plastic, titanium, chromium and other nonferrous metals, composite materials, stainless steel, reinforced concrete, colloids, soil. So to speak, in addition to the diamond and tempered glass (friable), there is no material that the high-pressure water jet cutting machine can not cut. And it can be safely cutting inflammable and explosive materials, as applied to the abandoned shells, bombs dismantled cutting.

Waterjet cutting small kerf (about 1-2MM), high cutting accuracy (0.0002mm), can be free to cut a variety of complex graphics, waterjet cutting incision smooth, no burrs, no heat no annealing phenomenon, cutting surface flat, widely used in aircraft parts, precision mechanical gear, printers, Walkman gear, parts and so on.

Waterjet has relatively high requirement for water, pipes, nozzle. Such as pipes, water jet is the use of high pressure tool after the water pressure and spray out, must have a very high pressure to cut the hard cutting materials, so the pipe must be able to withstand extremely high pressure, the pressure is much greater than 700 MPa, because thin steel plate (the material being cut) itself can withstand the pressure of 700MPa. Secondly, waterjet used water completely free of impurities is wrong. Because the pressure is much greater than 700MPa, for the pipeline and other sealing devices, no matter how good the sealing performance, pure water will always make them wear and leakage. To solve this problem, the water jet used water should add 5% soluble emulsified oil, improve the sealing effect. For the high-pressure pump, but also add some oil to improve the sealing performance.

Basic knowledge of waterjet abrasive

Abrasive has a significant effect on the performance of high-pressure water jets, especially in the abrasive water jet cutting, the choice of abrasive directly affects the cutting speed and the cutting surface quality. Many types of abrasives theoretically. According to sources can be divided into natural abrasive and artificial abrasive. Natural abrasive is made by minerals in nature crushing and screening, it is usually easier to impurities, but the cost is cheap; the second is artificial abrasive smelting by chemical methods, high purity, good performance, but the manufacturing process is complicated and expensive.

Garnet's chemical name: aluminum (calcium) silicate, to zhongtiao mountains garnet ore as raw materials, with the modern craft sticks refined, products high self-sharpening, grinding efficiency, sand consumption is low, wear parts good finish. The abrasive shell-shaped fracture, moderate hardness, good toughness, sharp corners, can be in continuous grinding new edges and side edges formed in the classification, make it better than other abrasive grinding, which has high hardness, specific gravity, chemical properties stable and unique self-sharpening of advantages, later also widely used in water jet cutting, therefore, also known as water jet sand. Natural almandine garnet because of its unique physical characteristics, high hardness, moderate cutting ability, no free silicon to become the best and most economical high-pressure water jet cutting medium.

According to the research, it is indicated that the water jet cutting any material has an optimum abrasive particle size, that is the same jet pressure and flow, can get the maximum cutting depth at a certain size, and increase or decrease the size, cutting depth are reduced accordingly. And for different hardness of the abrasive, for cutting different materials, the effect of different. For brittle materials, plastic materials and soft materials, the requirements of the abrasive are also different. For the same kind of abrasive, the same kind of cutting material, different water pressure and sand flow, the effect of cutting is also very great. Cutting process, water pressure and sand flow also has an optimal state.

Currently, the water jet grade garnet sand mainly 60 mesh, 80 mesh and 120 mesh, the basic is natural gravel screening process. The main origin of India, China, the United States, Australia and other regions, the domestic mainly concentrated in Hebei Xingtai and Lianyungang East China Sea area. In the price, the higher price of imported garnet sand, and lower price of domestic sand, quality is also very good.

Advantages of UHP waterjet removal method

UHP waterjet removal method has many advantages, we come to you about what the advantages of the ultra-high pressure waterjet removal method.

UHP waterjet removal technology

UHP waterjet removal is the use of ultra-high pressure (especially from 100MPa ~ 280MPa) water to remove the appearance of a certain thickness of the concrete. Wwhen the concrete surface is contaminated or damaged, high pressure water can be very effective in removing concrete surface without harming the steel bar in order to re-pouring concrete, so to maximize the use of resources.

Waterjet removal according to different requirements of engineering application, can achieve different effects

1, Low pressure: When the pressure is lower than 150MPa, only remove the concrete surface about 25mm, steel bar is not exposed;

2, High pressure: When the water pressure increases to the highest 280MPa, with appropriate feed mechanism, generally can penetrate concrete floor, make the steel bar totally exposed out;

UHP waterjet removal has the advantages that the other methods can not be compared:

1, More quickly and efficiently than traditional methods;

2, Not damaged parts basically can be reused, saving money;

3, Can remove the specified thickness as required;

4, It does not produce the appearance of cracks caused by the conventional method;

5, It does not damage the steel bar frame;

6, Minimum waste generated;

7, No damage caused by vibration;

8, Provide rough, irregular appearance, so re-pouring of the material with better adhesion;

9, It can reduce the sound conductivity;

10, Using automatic control of the robot or machinery can minimize human labor.

Waterjet cutting radius and radius compensation

A CNC water jet cutting machine consists of three parts: high pressure water jet generator (high pressure pump), CNC machining platform, water jet cutting head.Water jet has a high cutting efficiency, in order to let everyone Learn more waterjets, this time we give you knowledge on a waterjet lesson.

What is the cutting radius and radius compensation

When we use the waterjet cutting machine processing workpiece, we not only have to learn about waterjet system operation, but also to understand what is the cutting radius and radius compensation. For example, we want to cut a circular workpiece φ100mm, the water beam diameter φ1mm, then waterjet cutting path in accordance with a diameter of φ101mm circular path cutting (cutting trajectory is the track of cutting water beam center through, CAD / CAM software to generate the G code shows the motion coordinates, are the cutting trajectory coordinates), instead of a circle φ100mm, if the trajectory is φ100mm, then diameter of the final cutting workpiece is only φ99mm, peripheral is one cutting radius smaller than required φ100mm (ie, cutting water beam radius).

To compensate for this less cutting radius, in CAD / CAM software in the trajectory needs to be based on size of the workpiece plus one cutting radius (if you are cutting a hole, you should subtract one cutting radius), so-called radius compensation, in order to eventually be able to process the required size consistent workpiece.

Waterjet has very wide range of applications, from metal materials to non-metallic materials, from natural materials to artificial materials, from food to household items, basically can be cut, with the "universal cutting machine" reputation.

Classification of waterjet cutting machine

Waterjet cutting machine in operation will involves whether adding sand, so the device can be divided into pure water cutting and abrasive cutting two kinds; and from the body point of view, there is large waterjet cutting machine and small waterjet cutting machine points, respectively used for different cutting jobs. To distinguish from the amount of pressure used, the waterjet cutting machine can be divided into high pressure type and low pressure type, and even the ultra-high pressure type.

In a technical point of distinction, then, there are two types of waterjet cutting machines, respectively are pre-mixed type and post-mixed type. There is another kind of security as the basis of classification, including the safety cutting and non-safety cutting two kinds. When it comes to their respective areas of applications are also significantly different, such as low pressure type waterjet cutting can be used in dangerous chemical, petroleum, coal, hazardous materials handling, and other special industries; and abrasive waterjet cutting is mainly used in the mechanical processing industry.

Water jet cutting machine high pressure pressurization system is mainly the use of water running, when it is in the pressurizer after the high pressure to the cylinder piston will come out in further compression and vaporization. Thus, the water in the high-pressure turbocharger systems continue to be compressed so that the temperature rise and produce pressurized steam. Since the turbocharger is sealed, the water vapor due to expansion limited to form thermal power, resulting in waste water.

KOS teach you precisely adjust the waterjet pressure for cutting

With the popularity of waterjet cutting equipment, due to the waterjet cutting machine itself has many advantages, now the cutting processing industry people, are more and more using the waterjet as their cutting machine tools, but a lot of people are long-term waterjet fixed under the same pressure for the cutting operation, few people will according to different materials, different situations to reasonable adjust the water jet pressure. For each cutting sheet material is not the same, so the cutting pressure water jet cutting required is different, the following simple example and I will talk about why everyone in our water jet cutting, we need according to the cutting plate of different conditions (different materials, different thickness, etc.), the reasonable adjustment of water jet cutting pressure.

Waterjet through pressurized the water to generate high pressure water jet to cut the materials, but for different hardness, different thickness of materials, waterjet optimum cutting pressure is also not the same. Such as when cutting the ordinary stone, used to make mosaic are generally marble stone, relatively speaking not very high hardness, waterjet pressure preferably about 220MPa to 250Mpa. And if you want to cut the same thickness of the metal material, then waterjet pressure should reach 350MPa to 380MPa also added garnet sand can cut. So why not use the cutting metal pressure for cutting stone, waterjet is mechanical product, mechanical operation has its own speed, no matter how easy the material cutting, cutting speed is limited. The greater the waterjet pressure, the greater the cost of consumption, here including electricity costs, the loss of the machine wearing parts, and so on series of questions.

So if only cutting one material, then whether can not change the cutting pressure? Really, if only cutting one material, the beginning of the pressure is adjusted to the most suitable range, can be achieved without making adjustments. But waterjet, cars etc. all belong to machinery, driving people know that long-term driving in a speed range, is also damage to the car. So occasionally have to adjust the pressure appropriately to protect the machine, here only a little time to adjust, for the protection of the machine is much greater than the losses.

Portable waterjet and traditional waterjet complementary advantages

First, for ease of illustration, the following portable waterjet called "pre-mixed waterjet", the common traditional waterjet called "post-mixed waterjet".

The biggest difference between the two is that the different abrasive mixed mode. To illustrate the "pre-mix" was first described "post-mix". "Post-mixed waterjet" is after the high pressure waterjet nozzle, the negative pressure generated by the water jet make abrasive suction into sand mixing chamber and then through abrasive nozzle spray. "Pre-mixed waterjet" to save the high-pressure waterjet nozzle this part, set a larger capacity pressure vessel directly after high-pressure water produced in the high-pressure pump (similar to the "post-mixed waterjet" of energy storage device, but much larger), and add abrasive in this container (this is the technology key of "pre-mixed waterjet"), and then through the high-pressure pipeline transportation to abrasive nozzle.

These two kinds of waterjet technologies are different, resulting in large differences of the two technical performance. "Pre-mixed waterjet" working pressure is not suitable for too high, generally 20 ~ 50MPa, but the flow rate should not be too small, typically 8 ~ 30 L / min. The "post-mixed waterjet" working pressure generally in 200 ~ 400MPa or more, and the flow is relatively small, generally in the 2 ~ 4 L / min.

"Pre-mixed waterjet" advantages: at lower pressures, but also to achieve "post-mixed waterjet" cutting function. And because "the pre-mixed" reasons, structure of high-pressure pump portion is much simpler than the "post-mixed waterjet". Equipment failure rates and maintenance costs are much lower.

"Pre-mixed waterjet" the limitations are obvious: due to the special nature of the mixed-sand, leading to its work is intermittent. And during its working period, it is not suitable for jets frequently "on" "off".

In summary, the portable waterjet as a "pre-mixed waterjet" compare with "post-mixed waterjet" , almost no competition in the use, but a complementary relationship. Portable waterjet not suitable for CNC cutting like "post-mixed waterjet", and cutting efficiency is far less than "post-mixed waterjet". But in the wild or the random cutting task, portable waterjet come in handy. As for cutting inflammable explosive and other dangerous goods, both of which can do the job. The key depending on how many assignments and cutting thickness.

Another key is the device price: portable water jet cutting is generally equipped with simple settings, the cost is about 40,000 yuan. CNC waterjet, the most small model is 1 m * 1 m, the cost is about 100,000 yuan.

Waterjet pre-treatment of water

In different regions of our country and its water quality has a great difference, such as in most parts of the north, the water content of calcium and magnesium is relatively high, thus forming the so-called "hard water". As the ultra high pressure water jet pump equipment main medium of water, when the suspended solids or calcium and magnesium content exceeded, will resulting in a greater impact on system seal and high pressure parts service life. Therefore, it is necessary to pre-treatment of water entering the pump. Let's look at how the waterjet pre-treatment of water:

Waterjet cutting machine pre-treatment of water, including water filtration and water softening:

1, The main purpose of water filtration is to remove suspended solids in water, and it is usually realized by using multi-stage series filter device. Filter pump provides an initial pressure for the filter. Filters were equipped with 5μm, 1μm and 0.5μm of PP cotton filter. After triple filtered water will no longer be suspended solids, then after pressurized by a booster pump into the pressurizer. Filter stage usually requires the installation of a pressure differential table, through the filter when the filter clogging cause insufficient water pressure, the system will automatically stop and alarm to alert the operator to replace the filter in time to ensure system security.

2, The methods of softening water generally have boiling, ion exchange, reverse osmosis and other methods. The RH-1000 model softener as an example to introduce the basic principle of water softening and use.

(1) System function: The system uses 20μmPP cotton filter, activated carbon filter and 5μm ultrafilter series filter group, not only can remove the residual chlorine in water and suspended solids, and can effectively ensure the life of the resin. Softener resin used can effectively remove calcium and magnesium ions to achieve the effect of softened water. Softener with automatic regeneration.

(2) Water quality testing: to facilitate the understanding of the situation of water quality, can use water quality test reagent to test the water suspended solids, hardness and PH value. Let's take a look at it.

After softening water quality have a protective effect on the waterjet, prevent it from the "hard water" damage, prolong the service life.

Operation skills of using waterjet cutting machine

Operation skills:

1, Air gap when cutting, avoid cutting air gap is greater than 0.5mm. In the air gap in the nozzle divergent trend, it will cause the lower layer cutting surface roughness. Stack cutting, keep the sheet neatly stacked together.

2, Automatic loading and unloading, most machines do not use automatic loading and unloading techniques, such as the space shuttle.

3, Increase or decrease of water pressure by the controller.

4, Ordinary tap water, waterjet system uses ordinary tap water. 90% of pure waterjet and abrasive waterjet users require only water softening process to go through before the water filters through the pump into the turbocharger inlet. Reverse osmosis and deionization technology can greatly extend the life of the nozzle, but also cause costly damage to the turbocharger and high-pressure pipe.

5, Control system specially designed for the process, is usually more efficient and easier to use than the general multi process control.

Waterjet cutting mechanical features:

1, Can be configured dual cutting heads to increase productivity.

2, The actual cutting surface without burr, generally do not need the postprocessing.

3, Clean and safe process.

4, Low temperature processing, no dust and no harmful gases, are environmentally friendly.

5, Cutting fluctuation is absorbed by water, low noise.

6, By integrating the debris conveyor, continuous transport of waste abrasive and cutting excess material.

New technology in the waterjet cutting applications

In various processing industries, the pursuit of high-quality, high-efficiency direct forming process is currently the development trend of international, "waterjet" cutting machine is the response to this demand on the relevant technology innovation.

1, High-precision CNC machine tools

With the emergence of including precision ball screw, servo motor, resonance reduction unit and other technology, the machine tool can achieve higher position accuracy; and backlash compensation, repeat positioning accuracy improved, and the machine tool manufacturers will be more energy into to analyze the reasons for geometric error generated, so that by the use of the club measuring instrument and laser interferometer and other high-precision measuring instruments to detect geometric precision of machine tools and the establishment of a mapping table to give precision error correction, in order to manufacture high precision machine tools.

2, High power ultra high pressure system

Improve the energy of water, will enhance its cutting ability. The greater the energy of the water jet, the better the cutting performance, so the waterjet cutting machine pressure and maximum output flow has become the main parameters affecting the cutting ability. Currently, the international opinion on this are doing further research and testing, the test proved that when the pressure reaches 700MPa or more, also can use the pure water to cut thin steel plate and hard composite material, thus further improving the turbocharger pressure can greatly improve waterjet cutting machine cutting ability.

On the other hand, under the same pressure, increasing the flow rate of the jet (i.e. increasing the power of the jet) can also improve the cutting ability, thereby generating multi turbocharger parallel technology: under the premise of no major changes in the existing system, use multi turbocharger parallel technology, that's two or more high-voltage generator in parallel, can easily increase output flow of turbocharger, using large-diameter nozzle cutting, so water jet more efficient cutting energy, cutting effect better.
