[0001] This utility model relates to the field of pressure vessel and pipeline processing, and in particular to a CNC bending device for pressure vessel and pipeline that can realize variable diameter processing. Background Technology

[0002] Pressure vessel pipelines, as a key component of special equipment, play a crucial role in the transportation of gas or liquid in industrial production. Their safety and reliability directly affect the stable operation of the production system. In many industrial fields such as petrochemicals, energy and power, and shipbuilding, pressure vessel pipelines, as key components, directly impact the progress and quality of the entire project due to the quality and efficiency of their bending processing.

[0003] Existing pressure vessel pipe bending devices typically guide the pressure vessel pipe to move using rollers. When the pressure vessel pipe moves and contacts the bending roller, it is bent by the bending roller. However, since the current devices are usually fixed in structure, it is inconvenient to replace the bending roller and adjust its position, and it is not convenient to bend pressure vessel pipes of different diameters, which is quite inconvenient.

[0004] Therefore, it is necessary to design a CNC bending device for pressure vessel pipes that can easily replace bending wheels and rollers and adjust their positions, facilitate bending of pressure vessel pipes of different diameters, and facilitate adjustment of bending angles, and enable variable diameter processing. Summary of the Invention

[0010] As a preferred embodiment of this utility model, it further includes a support frame, a first motor, a guide wheel, a transmission assembly, a worm gear, a worm wheel, a cleaning brush, a spray frame, and a drying cylinder.

[0011] As a preferred technical solution of this utility model, the transmission component includes a flat belt and pulleys, and pulleys are connected to both the guide wheel and the front side of the worm gear, with a flat belt wound around the pulleys.

[0012] Compared with the prior art, the present invention has the following advantages: 1.

[0021] A CNC bending device for pressure vessel pipes capable of variable diameter machining, as shown in Figures 1, 2, 4, and 5, includes a worktable 1, a sliding frame 11, a second motor 12, a mounting rod 13, rollers 14, nuts 15, a double-acting lead screw 16, a slider 17, a bending wheel 18, and a single-acting lead screw 19. A drain pipe is located on the upper right side of the worktable 1 for wastewater discharge. The sliding frame 11 is slidably connected to both the front and rear parts of the worktable 1. Three second motors 12 are connected to the lower side of each sliding frame 11. The double-acting lead screw 16 is rotatably connected to the upper middle part of the worktable 1, and the sliding frame 11 is threadedly connected to the double-acting lead screw 16. A single-acting lead screw 19 is rotatably connected to the upper left part of the worktable 1. The double-acting lead screw... Both the 16 and the one-way lead screw 19 are equipped with handles on their front sides for easy gripping. The one-way lead screw 19 is threadedly connected to a slider 17, which is slidably connected to the worktable 1. The slider 17 is also connected to a second motor 12 on its lower side. The output shaft of the second motor 12 is connected to a mounting rod 13. The sliding frame 11 is rotatably connected to its adjacent mounting rod 13. The slider 17 is rotatably connected to its adjacent mounting rod 13. Rollers 14 are sleeved on the mounting rods 13 on the sliding frame 11. The rollers 14 have grooves to facilitate the guidance of the pressure vessel pipeline. A bending wheel 18 is sleeved on the upper part of the mounting rod 13 on the slider 17. Nuts 15 are threadedly connected to the upper part of the mounting rod 13.

[0022] As shown in Figures 1-3, the system also includes a support frame 2, a first motor 3, a guide wheel 4, a transmission assembly 5, a worm gear 6, a worm wheel 7, a cleaning brush 8, a spray frame 9, and a drying cylinder 10. The support frame 2 is connected to the upper right side of the worktable 1. The first motor 3 is connected to the upper rear side of the support frame 2. The guide wheel 4 is connected to the output shaft of the first motor 3. The guide wheel 4 is rotatably connected to the support frame 2. The worm gear 6 is rotatably connected to the upper right side of the worktable 1. A transmission assembly 5 is provided between the guide wheel 4 and the worm gear 6. The cleaning brush 8 is rotatably connected to the upper right side of the worktable 1. The cleaning brush 8 is located below the worm gear 6. The worm wheel 7 is connected to the outer side of the cleaning brush 8. The worm wheel 7 meshes with the worm gear 6. The spray frame 9 is connected to the upper right side of the worktable 1. The drying cylinder 10 is connected to the upper right side of the worktable 1.

[0023] As shown in Figures 2 and 3, the transmission assembly 5 includes a flat belt and pulleys. The guide wheel 4 and the front side of the worm 6 are both connected to pulleys, and a flat belt is wound around the pulleys.

[0024] When using this device, first place the workbench 1 in the pressure vessel pipe bending area, then place the pressure vessel pipe on the guide wheel 4 and pass it through the cleaning brush 8. Then, start the first motor 3 on the support frame 2 to drive the guide wheel 4 to rotate, causing the pressure vessel pipe to move within the cleaning brush 8. Simultaneously, connect an external water source through the spray frame 9 to spray cleaning water onto the surface of the pressure vessel pipe. The rotation of the guide wheel 4 will drive the pulley on the transmission component 5 to rotate, causing the flat belt to rotate, which in turn drives the worm gear 6 to rotate. The worm gear 6 and the worm wheel 7 mesh with each other, driving the cleaning brush 8 to rotate. The cleaning brush 8 cleans the surface of the pressure vessel pipe, and the drying cylinder 10 dries the surface of the pressure vessel pipe. This allows for cleaning of the pressure vessel pipe surface before bending, reducing impurities and improving bending quality. After cleaning, the pressure vessel pipe continues to move between the rollers 14. Then, start the second motor 12 to drive the mounting rod 13 to rotate, causing the rollers 14 and the bending wheel 18 to rotate. The rollers 14 guide the movement. When the pressure vessel pipe contacts the bending wheel 18... At 8 o'clock, the pressure vessel pipeline is bent by the bending wheel 18. When it is necessary to bend pressure vessel pipelines of different diameters, the nut 15 can be loosened by rotating, and then the bending wheel 18 and roller 14 can be removed from the mounting rod 13. The bending wheel 18 and roller 14 can then be replaced and put on the mounting rod 13. Then the nut 15 is connected to the mounting rod 13 and the nut 15 is tightened by rotating, so that the nut 15 contacts the upper side of the bending wheel 18 and roller 14 respectively. Then the double-acting screw 16 is rotated, so that the sliding frame 11 is advanced under the action of the thread. The sliding frame 11 moves closer together, so that the groove on the roller 14 fits the pressure vessel pipe, which can guide the pressure vessel pipes of different diameters. Then, the one-way screw 19 is rotated, so that the slider 17 moves under the action of the thread, which drives the bending wheel 18 to move. The bending angle of the pressure vessel pipe can be controlled by adjusting the position of the bending wheel 18, so that the bending wheel 18 and the roller 14 can be replaced and their positions can be adjusted, which is convenient for bending pressure vessel pipes of different diameters and for adjusting the bending angle.
