Description

Technical Field

[0001] This utility model relates to the manufacturing and processing of waterjet cutting machines, and more particularly to an automatic high-pressure pipe bending machine. Background Technology

[0002] A waterjet cutting machine is a machine that uses high-pressure water jets for cutting. It is one of the most productive machines in the world. Waterjet cutting is also known as water jet cutting.

[0003] The core component of a waterjet cutting machine is high-pressure water, which is generated by a high-pressure water pump. The high-pressure water pump delivers high-pressure water to the cutter head on the waterjet cutting machine. The high-pressure water mixes with abrasive to cut the product.

[0004] To ensure the effective delivery of high-pressure water, the high-pressure water generated by the high-pressure water pump is transported through a high-pressure pipe connected to it. This high-pressure pipe, specifically designed for high-pressure water pumps, is typically made of metal, offering high strength and flexibility to be bent and deformed according to the structure of the waterjet cutting machine, facilitating installation and connection.

[0005] In the production and processing of waterjet cutting machines, the high-pressure pipes used for high-pressure water delivery are all manually bent. Operators clamp a long, straight pipe onto a chuck and manually bend the pipe using a horizontally rotating bending head. This bending head has a groove for the high-pressure pipe to be inserted into. One end of the pipe is fixed to the chuck, and the pipe body is inserted into the groove. The bending head is then rotated to perform the bending. However, this method of bending high-pressure pipes lacks precision; the bending angle and length are determined by manual intuition, affecting the processing quality of the waterjet cutting machine. Furthermore, the bending efficiency is low, impacting the equipment manufacturing process. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide an automatic high-pressure pipe bending machine that can facilitate the automatic bending and forming of high-pressure pipes on waterjet cutting machines.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] An automatic high-pressure pipe bending machine includes a base and a worktable fixedly mounted on the base. A connecting hole with vertical connection is provided at the center of the top of the worktable near one end. A bearing is fixedly connected to the connecting hole. Below the bearing is a second servo motor fixedly connected to the bottom of the worktable. The second servo motor is electrically connected to a PLC controller mounted on the worktable. A bending mechanism is movably connected to the bearing, and the bending mechanism is driven by the second servo motor through the bearing. A linear module is provided on one side of the bending mechanism on the worktable, and the linear module is electrically connected to the PLC controller. The linear module slides... The top of the platform is equipped with a hexagonal shank chuck and a first servo motor that is drivenly connected to the hexagonal shank chuck. The first servo motor is electrically connected to the PLC controller and can control the clamping part of the hexagonal shank chuck to open, close, and rotate. The hexagonal shank chuck corresponds to the bending mechanism, and a high-pressure pipe is clamped in the clamping part of the hexagonal shank chuck. A mounting block is provided on the worktable between the linear module and the bending mechanism. The top of the mounting block is equipped with a guide mechanism that corresponds to the linear module and the bending mechanism. The high-pressure pipe passes through the guide mechanism and extends above the bending mechanism. The high-pressure pipe is bent by the guide post provided on the top of the bending mechanism.

[0009] Furthermore, the guiding mechanism includes a guide seat, the bottom of which is fixedly connected to the mounting block. One end of the guide seat corresponding to the bending mechanism protrudes and is suspended above the top of the bending mechanism, and its top surface height is not higher than the top height of the guide post. A limiting groove is provided on the top of the guide seat. The limiting groove passes through the parts of the guide seat corresponding to the hexagonal shank chuck and both ends of the bending mechanism. The end of the limiting groove corresponds to the clamping part on the hexagonal shank chuck. The high-pressure pipe clamped on the hexagonal shank chuck passes through the limiting groove and extends above the top of the bending mechanism.

[0010] Furthermore, the end of the protruding part on the guide seat corresponding to the bending mechanism is a vertical arc transition part, and the parts on both sides of the protruding part on the guide seat are concave arc connecting parts.

[0011] Furthermore, a shim is provided between the guide seat and the mounting block.

[0012] Furthermore, a limiting block is provided at the top of the limiting groove, which is fixedly connected to the guide seat.

[0013] Furthermore, a guide groove is provided on the outer periphery of the guide post. The width of the guide groove is at least greater than the diameter of the high-pressure pipe, and the height of the guide groove is consistent with the horizontal height of the high-pressure pipe on the hexagonal shank chuck.

[0014] Furthermore, the bending mechanism includes a cylindrical rotary table, with a shaft connector fixedly connected to the bottom center of the rotary table. The shaft connector is sleeved in the bearing, and its lower end passes through the bearing and is connected to the drive shaft of the second servo motor. The guide column is fixedly installed on the top of the rotary table near the edge, and the rotary table can drive the guide column to move synchronously.

[0015] Compared with the prior art, the advantages of this utility model are: this high-pressure pipe automatic bending machine uses a linear module to realize the forward and backward movement and rotation of the high-pressure pipe clamped at the top, and can perform horizontal bending of the high-pressure pipe through the bending mechanism, realizing automatic bending processing of high-pressure pipe, improving product processing efficiency, and the bending accuracy of high-pressure pipe is significantly improved compared with manual bending, ensuring the assembly quality of waterjet cutting machine.

[0027] Example

[0028] Please refer to the instruction manual attached. Figures 1 to 3 As shown, the instruction manual is attached. Figure 4 The diagram shows an automatic high-pressure pipe bending machine of this utility model, used for bending and forming high-pressure pipes for high-pressure water transmission in waterjet cutting machines. In this embodiment, the automatic high-pressure pipe bending machine includes a base 1 and a worktable 11 fixedly mounted on the base 1. The top of the worktable 11 is horizontal, and a connecting hole with vertical connection is provided at the center of one end of the top. A bearing 81 is fixedly connected to the connecting hole. Below the bearing 81, a second servo motor 8 is fixedly connected to the bottom of the worktable 11. The second servo motor 8 is electrically connected to a PLC controller 2 mounted on the worktable 11. The PLC controller 2 can control the drive shaft inside the second servo motor 8 to rotate clockwise or counterclockwise. A bending mechanism 7 is movably connected to the bearing 81, and the bending mechanism 7 is connected to the second servo motor 8 via the bearing 81. A linear module 3 is provided on one side of the bending mechanism 7 on the worktable 11, and the linear module 3 is connected to the PLC... The controller 2 is electrically connected, and the PLC controller 2 can control the slide table on the linear module 3 to move along its length direction. The top of the slide table 31 of the linear module 3 is provided with a hexagonal shank chuck 4 and a first servo motor 41 that is drivenly connected to the hexagonal shank chuck 4. The first servo motor 41 and the hexagonal shank chuck 4 can move synchronously with the slide table 31. The first servo motor 41 is electrically connected to the PLC controller 2, and it can control the clamping part of the hexagonal shank chuck 4 to open, close and rotate. The hexagonal shank chuck 4 corresponds to the bending mechanism 7. The clamping part of the hexagonal shank chuck 4 is fitted with a high-pressure pipe 9. After the hexagonal shank chuck 4 clamps the high-pressure pipe 9, it can drive the high-pressure pipe 9 to rotate, and it can be driven to move by the linear module 3. The worktable 11 is provided with a mounting block 5 located between the linear module 3 and the bending mechanism 7. The top of the mounting block 5 is provided with a guide mechanism 6 that corresponds to the linear module 3 and the bending mechanism 7.

[0029] Please refer to the instruction manual attached. Figure 4As shown, the guiding mechanism 6 includes a guide seat 61. The bottom of the guide seat 61 is fixedly connected to the mounting block 5 by bolts. To adjust the height of the guide seat 61 as required, a shim 51 is provided between the guide seat 61 and the mounting block 5. The shim 51 is fixedly connected to the mounting block 5 by bolts, and the guide seat 61 is fixedly connected to the shim 51 by bolts. One end of the guide seat 61 corresponding to the bending mechanism 7 protrudes and is suspended above the top of the bending mechanism 7. The end of the protruding part of the guide seat 61 corresponding to the bending mechanism 7 is a vertical arc transition part 613, which facilitates a certain arc transition when the high-pressure pipe 9 is bent, avoiding direct bending and damage to the high-pressure pipe. A limiting groove 611 is provided on the top of the seat 61 for guiding and supporting the high-pressure pipe 9. The limiting groove 611 passes through the parts on the guide seat 61 corresponding to the two ends of the hexagonal shank chuck 4 and the bending mechanism 7, and the end of the limiting groove 611 corresponds to the clamping part on the hexagonal shank chuck 4. In order to prevent the high-pressure pipe in the limiting groove 611 from jumping out of the guide seat 61, a limiting block 614 fixedly connected to the guide seat 61 is provided on the top of the limiting groove 611. The high-pressure pipe 9 located in the limiting groove 611 is restricted by the limiting block 614 during the bending process and is not easy to jump out of the limiting groove 611. The front end of the high-pressure pipe 9 clamped on the hexagonal shank chuck 4 passes through the limiting groove 611 and extends above the top of the bending mechanism 7.

[0030] Please refer to the instruction manual attached. Figure 4As shown, the bending mechanism 7 includes a cylindrical rotary table 71. A guide post 72 is mounted on the rotary table 71 and threadedly connected to it. The lower end of the guide post 72 has a threaded connection portion. A threaded connection hole is located near the outer periphery of the rotary table 71, and the guide post 72 is screwed into this hole. It should be noted that the top surface height of the guide seat 61 is not higher than the top height of the guide post 72. The guide post 72 is fixedly mounted on the top of the rotary table 71 near its edge. A shaft connector 711 is fixedly connected to the center of the bottom of the rotary table 71. The shaft connector 711 is integrally formed with the rotary table 7 and is fitted into the bearing 81. The lower end of the shaft connector 711 passes through the bearing 81 and connects to the transmission shaft of the second servo motor 8. The rotating table 71 can drive the guide post 72 to move synchronously. In order to ensure the horizontality of the high-pressure pipe 9 when bending it, and to ensure the bending effect and accuracy, the guide post 72 is provided with a guide groove 721 on its outer periphery. The width of the guide groove 721 is at least greater than the diameter of the high-pressure pipe 9, and the height of the guide groove 721 is consistent with the horizontal height of the high-pressure pipe 9 on the hexagonal shank chuck 4. In order to maximize the range of circumferential movement of the guide post 72, the parts on both sides of the protruding part of the guide seat 61 are concave arc-shaped connecting parts 612, which facilitate the high-pressure pipe 9 to bend horizontally at 180° through the guide post 72. The high-pressure pipe 9 passes through the guide mechanism 6 and extends above the bending mechanism 7. The high-pressure pipe 9 is bent by the guide post 72 provided at the top of the bending mechanism 7.

[0031] During operation, one end of the high-pressure tube 9 is clamped and fixed by the hexagonal shank chuck 4, and the other end extends through the limiting groove 611 on the guide seat 61 and above the top of the rotary table 71. The rotary table 71 is driven to rotate by the second servo motor 8. The rotary table 71 drives the guide post 72 to rotate synchronously. The guide post 72 can be bent along the protrusion at the end of the guide seat 61. At the same time, the linear module 3 drives the first servo motor 41 and the hexagonal shank chuck 4 to move through its slide 31. This allows the high-pressure tube 9 to move in the direction of the bending mechanism 7. The first servo motor 41 can drive the hexagonal shank chuck 4 to rotate, so that the clamped high-pressure tube 9 can be rotated. The high-pressure tube 9 can be bent into the required shape according to the settings. The dimensional control of the high-pressure tube 9 during bending is highly accurate and flexible.

[0032] This high-pressure pipe automatic bending machine uses a linear module 3 to move and rotate the high-pressure pipe 9 clamped at the top. The bending mechanism 7 can bend the high-pressure pipe 9 horizontally, realizing automatic bending of the high-pressure pipe 9, improving the processing efficiency of the product, and the bending accuracy of the high-pressure pipe 9 is significantly improved compared with manual bending, ensuring the assembly quality of the waterjet cutting machine.

[0033] It should be emphasized that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
