Description

Technical Field

[0001] This invention belongs to the field of waterjet cutting, specifically a small portable ultra-high pressure waterjet cutting machine. Background Technology

[0002] High-pressure water jet cutting uses water as a medium and applies the principle of liquid pressurization to convert the mechanical energy of the power source into the pressure energy of the water, and then convert the pressure energy into kinetic energy. The high-pressure generator then pressurizes the water to obtain enormous energy, forming a high-speed water jet that is sprayed onto the surface of the workpiece. When the water jet impacts the workpiece, if the pressure energy exceeds the material's breaking strength, the material can be cut off, achieving the processing purpose of removing the material.

[0003] Waterjet cutting is a type of cold cutting, which has gained widespread application due to its advantages such as no sparks and being environmentally friendly. It is mainly used in aerial bomb disposal, petrochemical pipeline cutting, hazardous materials handling, and cutting of flammable and explosive materials.

[0004] However, most existing waterjet cutting equipment is large-scale CNC waterjet cutting equipment. Due to its large size, it can only work and produce in a fixed position, which limits the application of waterjet cutting. In addition, most existing waterjet cutting equipment has only one pipeline, and the pipeline may be damaged under ultra-high pressure operation, thus affecting its use.

[0005] To solve the above problems, it is necessary to propose a small portable ultra-high pressure water jet cutting machine. The present invention is small in size, can be held by hand, and is easy to carry. Furthermore, the present invention is equipped with two boxes and a water inlet pipe. The first pressurization is performed by compression. When the rack moves to the left or right, it will alternately complete the liquid discharge pressurization and liquid suction processes in its respective boxes. This not only improves the efficiency of the conveying work, but also allows the other pipe to be used normally when one pipe is abnormal. Summary of the Invention

[0006] The purpose of this invention is to provide a small, portable ultra-high pressure water jet cutting machine. This invention is small in size, handheld, and easy to carry. Furthermore, this invention is equipped with two chambers and a water inlet pipe. The initial pressurization is achieved through compression. When the rack moves to the left or right, it alternately completes the liquid discharge, pressurization, and liquid suction processes in its respective chambers. This not only improves the efficiency of the conveying process, but also ensures that if one pipe malfunctions, the other pipe can still be used normally.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: a small portable ultra-high pressure water jet cutting machine, comprising a controller and a machine body, wherein the top and bottom of the machine body are respectively connected to a water inlet and a water outlet;

[0008] The first tube is fixedly connected to the top wall of the machine body;

[0009] The inner wall of the machine is fixedly connected to a left box and a right box; the top of the left box and the right box are both connected to a water inlet pipe, and the water inlet pipe is connected to the first pipe; the water inlet pipe is connected to the first valve that is fixedly connected to it.

[0010] A motor is installed on the inner wall of the machine body. The motor is electrically connected to the controller. The output shaft of the motor is coaxially fixedly connected to a gear. A rack meshes on the gear. The two ends of the rack extend into the left and right boxes respectively. Piston plates are fixedly connected to the two ends of the rack respectively. The two piston plates are located in the left and right boxes respectively. The bottom of the left and right boxes are connected and fixedly equipped with a second valve.

[0011] A booster pump is installed on the inner wall of the machine body. The input end of the booster pump is connected to a connecting pipe, and the end of the connecting pipe away from the booster pump is connected to a third pipe. The second valve is connected to the third pipe. The output end of the booster pump is connected to a fourth pipe, and the end of the fourth pipe away from the booster pump is connected to the water outlet. The connection between the water outlet and the fourth pipe is connected to a fourth valve. An infrared rangefinder is installed at the bottom of the first pipe, and the infrared rangefinder is electrically connected to the controller.

[0012] The above scheme achieves the following principles and beneficial effects:

[0013] In use, the inlet is connected to an external water source, and the abrasive is mixed with water. The mixture is then transported through the inlet to the first pipe, and then through the first pipe and the first valve to the left and right boxes. At the same time, the motor drives the gear to rotate forward, and the gear drives the rack to move to the left. When the gear rotates to the maximum stroke of the rack to the left, the motor drives the gear to rotate in reverse under the control of the controller. The gear then drives the rack to move to the right, thereby pushing the piston plates in the left and right boxes to move closer to the second valve, thus reducing the volume of the mixed mixture stored in the left and right boxes.

[0014] For example, when the piston plate in the left tank moves towards the second valve, the volume of the mixture stored in the left tank decreases. However, when the amount of mixture in the left tank remains unchanged or when the mixture is continuously supplied to the left tank from the outside, the water pressure in the left tank will increase to a certain extent. At the same time, the infrared rangefinder measures the movement of the rack to the left and transmits this information to the controller. Based on this information, the controller opens the second valve at the left tank. The water in the left tank is then sequentially transported through the second valve to the third pipe, the connecting pipe, and the booster pump. The mixture is then pressurized again by the booster pump and transported to the outlet. The fourth valve at the outlet is then opened, and the high-pressure, high-speed mixture is jetted out through the outlet, forming a "water jet" at the outlet to cut objects.

[0015] The difference between this invention and the prior art is that this invention is smaller in size, can be held by hand, and is easy to carry; and this invention is equipped with two boxes and a water inlet pipe. The first pressurization is performed by compression. When the rack moves to the left or right, it will alternately complete the liquid discharge pressurization and liquid suction processes in its respective boxes. This not only improves the efficiency of the conveying work, but also allows the other pipe to be used normally if one pipe is abnormal.

[0016] Furthermore, it also includes a vertical rod with a slide rail, on which a horizontal plate slides laterally, and the horizontal plate has several water holes; the bottom of the vertical rod is detachably connected to a base.

[0017] Beneficial effects: When using this device, the base can be fixed on the support surface. The fixing method can be negative pressure adsorption, bolt fixing, etc., and then the water outlet is placed at the water hole.

[0018] Furthermore, the diameter of the water holes decreases sequentially from front to back.

[0019] Beneficial effects: When the outlet is placed at the water hole, the diameter of the mixed liquid jet will be different due to the different sizes of the water holes. Under the same water pressure, the smaller the cross-sectional area of ​​the mixed liquid outflow, the stronger its jet power.

[0020] Furthermore, a nozzle is detachably connected to the water outlet; there are several nozzles with different pipe diameters.

[0021] Beneficial effect: The nozzle of the appropriate size can be selected and installed according to the actual situation to fit water holes of different sizes.

[0022] Furthermore, the slide rail is hinged to the vertical rod.

[0023] Beneficial effect: When not in use, the slide rail can be rotated to the same vertical plane as the vertical rod, making it easy to carry and transport.

[0024] Furthermore, the cross plate and the slide rail are detachably connected.

[0025] Beneficial effect: The horizontal bar can be removed from the slide rail, and then the slide rail can be rotated to be on the same vertical plane as the vertical bar, making it easy to carry and transport.

[0026] Furthermore, a handle is fixedly connected to the outer wall of the machine body.

[0027] Beneficial effect: The device is more convenient to use by holding it in your hand.

[0028] Furthermore, the handle is fitted with a non-slip sleeve.

[0029] Beneficial effect: Anti-slip sleeves can increase stability when gripping the handle to a certain extent. Attached Figure Description

[0033] The following detailed description illustrates the specific implementation method:

[0034] The reference numerals in the accompanying drawings include: body 1, inlet 2, outlet 3, first pipe 4, infrared rangefinder 6, left box 7, right box 8, first valve 9, second valve 10, connecting pipe 11, fourth valve 12, gear 13, rack 14, third pipe 15, booster pump 16, vertical rod 17, slide rail 18, horizontal plate 19, water hole 20, nozzle 21.

[0035] Example 1

[0036] The basic implementation examples are as follows: Figure 1-3 As shown:

[0037] A small portable ultra-high pressure water jet cutting machine includes a controller and a body 1. The preferred model of the controller is SPC-STW-S0402CTR. The top and bottom of the body 1 are respectively connected to a water inlet 2 and a water outlet 3.

[0038] The first pipe 4 is fixedly connected to the inner top wall of the body 1 by a clamp;

[0039] The inner wall of the machine body 1 is fixedly connected to the left box 7 and the right box 8 by bolts; the top of the left box 7 and the right box 8 are both connected to the water inlet pipe, and the water inlet pipe is connected to the first pipe 4; the water inlet pipe is connected to the first valve 9 which is fixedly connected to it.

[0040] A motor (not shown in the figure) is bolted to the inner wall of the body 1. The preferred model of the motor is 37GB-3530. The motor is electrically connected to the controller. The output shaft of the motor is coaxially connected to a gear 13 by bolts. A rack 14 meshes with the gear 13. The two ends of the rack 14 extend into the left box 7 and the right box 8, respectively. Piston plates are welded to the two ends of the rack 14, and the two piston plates are located in the left box 7 and the right box 8, respectively. The bottoms of the left box 7 and the right box 8 are connected and bolted to a second valve 10.

[0041] A booster pump 16 is installed on the inner wall of the body 1. The booster pump 16 is preferably of model JKB15-22Z. The input end of the booster pump 16 is connected to a connecting pipe 11. The end of the connecting pipe 11 away from the booster pump 16 is connected to a third pipe 15. The second valve 10 is connected to the third pipe 15. The output end of the booster pump 16 is connected to a fourth pipe. The end of the fourth pipe away from the booster pump 16 is connected to the water outlet 3. The connection between the water outlet 3 and the fourth pipe is connected to a fourth valve 12. An infrared rangefinder 6 is installed at the bottom of the first pipe 4. The infrared rangefinder 6 is preferably of model GLM150C. The infrared rangefinder 6 is electrically connected to the controller.

[0042] The specific implementation process is as follows:

[0043] Before use, open the first valve 9, the motor, and the infrared rangefinder 6. During use, connect the water inlet 2 to the external water source. In this embodiment, the external water source can be a water tank. Mix the abrasive with water. The mixture is transported to the first pipe 4 through the water inlet 2, and then to the left box 7 and the right box 8 through the first pipe 4 and the first valve 9. At the same time, the motor drives the gear 13 to rotate forward, and the gear 13 drives the rack 14 to move to the left. When the gear 13 rotates forward to the maximum stroke of the rack 14 to move to the left, the motor drives the gear 13 to rotate in reverse under the control of the controller. The gear 13 then drives the rack 14 to move to the right, thereby pushing the piston plates in the left box 7 and the right box 8 to move closer to the second valve 10, so that the volume of the mixed liquid stored in the left box 7 and the right box 8 decreases.

[0044] For example, when the piston plate in the left chamber 7 moves toward the second valve 10, the volume of the mixed liquid stored in the left chamber 7 decreases. When the volume of the mixed liquid in the left chamber 7 remains constant or when the mixed liquid is continuously supplied to the left chamber 7 from the outside, the water pressure in the left chamber 7 will increase to a certain extent, while the right chamber 8 undergoes a liquid suction process (at this time, the abrasive and water are fully mixed; due to the high-pressure water flow rate, insufficient mixing of the abrasive and water may occur, resulting in poor cutting effect; specifically, the dwell time at the cutting position is longer. Alternating the flow can make the abrasive and water more uniform, improving the cutting effect, reducing the dwell time at the cutting position, and increasing cutting efficiency). Simultaneously... Infrared rangefinder 6 detects that rack 14 moves to the left and transmits this information to controller. Based on this information, controller opens the second valve 10 at left tank 7. The mixture in left tank 7 is then sequentially transported through the second valve 10 to the third pipe 15, connecting pipe 11, and booster pump 16. The mixture is then pressurized again by booster pump 16 and transported to outlet 3. The fourth valve 12 at outlet 3 is opened, and the high-pressure, high-speed mixture is jetted out through outlet 3, forming a "water jet" at outlet 3 to cut the object. Of course, the working principle of right tank 8 is the same. This continuous reciprocating motion forms a water jet, ensuring the uniformity of abrasive and water.

[0045] When the rack 14 moves to the left or right, it will alternately complete the liquid discharge pressurization and liquid suction processes in the left box 7 and the right box 8. By setting up the left box 7 and the right box 8, two water inlet pipelines are established, which not only improves the efficiency of the conveying work, but also allows the other pipeline to be used normally when one pipeline is abnormal.

[0046] Example 2

[0047] The difference from the above embodiment is that it also includes a vertical rod 17, a slide rail 18 on the vertical rod 17, a horizontal plate 19 that slides laterally on the slide rail 18, and a number of water holes 20 on the horizontal plate 19; a base is detachably connected to the bottom of the vertical rod 17.

[0048] The specific implementation process is as follows: When using the device, the base can be fixed on the support surface. The fixing method can be negative pressure adsorption, bolt fixing, etc. Then, the water outlet 3 is placed at the water hole 20; the vertical rod 17 and the horizontal plate 19 are set to support the body 1.

[0049] Example 3

[0050] The difference from the above embodiment is that the diameter of the water hole 20 decreases from front to back.

[0051] The specific implementation process is as follows: When the outlet 3 is placed at the water hole 20, the diameter of the mixed liquid jet will be different because the size of the water hole 20 is different. Under the condition of consistent water pressure, the smaller the cross-sectional area of ​​the mixed liquid outflow, the greater the water pressure of the jet will be, thus making the jetting power more sufficient.

[0052] Example 4

[0053] The difference from the above embodiment is that: a nozzle 21 is detachably connected to the water outlet 3; there are several nozzles 21, and their pipe diameters are different.

[0054] The specific implementation process is as follows: nozzles 21 of corresponding size can be selected and installed according to the actual situation to fit water holes 20 of different sizes.

[0055] Example 5

[0056] The difference from the above embodiment is that the slide rail 18 is hinged to the vertical rod 17.

[0057] The specific implementation process is as follows: When the device is not in use, the slide rail 18 can be rotated to the same vertical plane as the vertical rod 17, which makes it easier to carry and transport to a certain extent.

[0058] Example 6

[0059] The difference from the above embodiment is that the horizontal plate 19 and the slide rail 18 are detachably connected.

[0060] The specific implementation process is as follows: When the device is not in use, the horizontal plate 19 can be removed from the slide rail 18, and then the slide rail 18 can be rotated to the same vertical plane as the vertical rod 17, which makes it easier to carry and transport to a certain extent.

[0061] Example 7

[0062] The difference from the above embodiment is that a handle is fixedly connected to the outer wall of the body 1 by bolts.

[0063] The specific implementation process is as follows: When using the device, it can be held by the handle. The handle design can increase the practicality of the device to a certain extent and make it more convenient. When the "water jet" is formed, it will generate a certain impact force, which may cause damage to the user's hands. The handle can buffer the impact force to a certain extent, thereby reducing the damage to the user's hands.

[0064] Example 8

[0065] The difference from the above embodiment is that the handle is covered with a non-slip sleeve.

[0066] The specific implementation process is as follows: The anti-slip sleeve has strong friction, which can increase the stability when holding the handle to a certain extent.
