Description

Technical Field

[0001] This invention relates to the field of pipe fitting processing technology, and more specifically to a metal parts processing apparatus. Background Technology

[0002] When processing irregularly shaped pipe fittings connecting large-diameter and small-diameter pipes, it is necessary to chamfer the ends to remove burrs, which facilitates assembly and improves sealing reliability. This is an indispensable key process. The irregularly shaped pipe fitting has a large-diameter end, a small-diameter end, and a tapered transition section, and the large-diameter end, small-diameter end, and tapered transition section are coaxially arranged. In actual production, especially in small-batch production, maintenance, or R&D trial production, purchasing dedicated chamfering equipment often faces the problems of high cost and insufficient flexibility. Therefore, production sites generally tend to use existing general-purpose machine tools, such as vertical drilling machines, to complete this task by adding chamfering tools. For example, the spindle function of the vertical drilling machine can be converted from drilling to chamfering, that is, a dedicated chamfering tool can be installed in the drill chuck, and the metal tapered pipe fitting can be fixed on the worktable by a specific fixture. The pipe end can be cut by the downward feed of the spindle.

[0003] Chinese patent document CN110202200B discloses a chamfering machine, including a first conveying mechanism with a first conveyor belt inside. A first chamfering mechanism is located after the exit of the first conveying mechanism. A first pushing cylinder is designed on the other side of the exit of the first conveying mechanism, which can push the workpiece into the working surface of the first chamfering mechanism. A three-jaw chuck is provided inside the first chamfering mechanism for clamping the workpiece. After the workpiece falls into the working surface, the three-jaw chuck clamps the workpiece for chamfering. A workpiece flipping mechanism is located after the three-jaw chuck, with a receiving cavity inside. The first pushing cylinder can push the workpiece into the receiving cavity after the first chamfering is completed. The receiving cavity can be rotated 180 degrees along the chamfered plane of the workpiece, thereby causing the workpiece to rotate. A second conveying mechanism is set behind the workpiece rotating mechanism, and a second conveyor belt is set inside the second conveying mechanism. After the workpiece is rotated, it falls into the second conveying mechanism. A second pushing cylinder is set on one side of the second conveyor belt, and a second chamfering mechanism is set on the other side of the second pushing cylinder. When the workpiece is conveyed to the position of the second pushing cylinder, the second pushing cylinder can push the workpiece into the working surface of the second chamfering mechanism. A three-jaw chuck for clamping the workpiece is set inside the second chamfering mechanism. A third pushing cylinder is set on one side of the second chamfering mechanism, and a workpiece outlet is set on the other side of the second chamfering mechanism. After the workpiece is clamped by the three-jaw chuck, it is processed. After processing, it is released, and the third pushing cylinder pushes the workpiece to the outlet to complete the processing.

[0004] However, the above patent still has the following shortcomings: When cutting the large-diameter end of the irregular pipe fitting, the irregular pipe fitting is first placed into the jaws of the clamp. At this time, there is a natural gap between the irregular pipe fitting and the clamp. If the irregular pipe fitting is simply placed into the jaws and then clamped by the clamp, the irregular pipe fitting may shift due to gravity or slight differences in the placement angle, which will affect the cutting and chamfering effect of the irregular pipe fitting. Summary of the Invention

[0005] This invention provides a metal parts processing apparatus, which aims to solve the problem in related technologies that irregularly shaped tubes may shift due to slight differences in gravity or placement angle, thereby affecting the cutting and chamfering effect of the irregularly shaped tubes.

[0006] The metal parts processing apparatus of the present invention includes a worktable, a clamping mechanism, and a cutting mechanism. The clamping mechanism includes a clamping part one and a clamping part two for clamping and fixing irregularly shaped tubes, with the large end of the irregularly shaped tube facing upward and the small end facing downward. The apparatus also includes an adjustment mechanism, which includes a holding ring for holding the irregularly shaped tube and four pushers that operate synchronously and apply downward force to the irregularly shaped tube. The four pushers are arranged in a ring. The holding ring is rotatable along its own axis. The pushers include a pusher wheel that is rotatable and applies downward force to the irregularly shaped tube.

[0007] Beneficial effects: When machining the large-diameter end of a shaped pipe fitting, the fitting is first placed in the holding ring with the large-diameter end facing upwards and the small-diameter end facing downwards. Then, the clamping mechanism is activated, driving the clamping part two and clamping part one to clamp and fix the shaped pipe fitting. During this process, the four pushing parts in the adjusting mechanism operate synchronously, and the holding ring rotates along its own axis, so that the pushing wheels in the four pushing parts apply a downward pushing force to the shaped pipe fitting. In conjunction with the rotating holding ring, the placement position of the shaped pipe fitting can be adjusted until clamping part two and clamping part one form a clamp and fixation of the shaped pipe fitting, so as to avoid the clamped shaped pipe fitting from shifting, thereby avoiding affecting the subsequent cutting and chamfering effect of the shaped pipe fitting.

[0008] Preferably, the inner side of the holding ring is provided with a tapered hole, which is coaxially arranged with the arc groove on the clamping part, and the tapered hole on the holding ring is adapted to the outer side of the tapered transition section on the irregular tube.

[0009] Its effect is that the tapered hole inside the holding ring matches the tapered transition section on the irregularly shaped pipe, making it easier to position the irregularly shaped pipe.

[0010] Preferably, the clamping part one is fixedly connected to the worktable, the clamping part two is slidably disposed on the worktable, the clamping part two can move toward or away from the clamping part one, and the clamping mechanism further includes a driving member one, the driving member one includes a toothed ring fixedly connected to the outside of the holding ring, and a toothed plate fixedly connected to the clamping part two for meshing and transmission with the toothed ring.

[0011] Its effect is that when the clamping part 2 moves on the worktable, the driving part 1 drives the container ring to rotate. Specifically, the toothed plate moves with the clamping part 2 and meshes with the toothed ring to drive the rotation of the toothed ring. When the toothed ring rotates, it drives the container ring to rotate, thereby providing power for the rotation of the container ring.

[0012] Preferably, the pushing component further includes a fixed seat fixedly connected to the worktable and a rotating shaft fixedly connected to the pushing wheel and rotatably connected to the fixed seat. The adjustment mechanism further includes a second driving component for driving the rotating shaft to rotate so as to drive the pushing wheel to rotate.

[0013] Its effect is that the rotating shaft is driven to rotate on the fixed seat by the driving component, which can provide power for the rotation of the drive wheel.

[0014] Preferably, the top of the workbench is provided with a first mounting cavity and a second mounting cavity for accommodating the second driving component. The first mounting cavity and the second mounting cavity are connected, and the pushing component is fixedly installed in the first mounting cavity.

[0015] Its effect is that the mounting cavity one and mounting cavity two can provide space to accommodate the driving component two and the pushing component.

[0016] Preferably, the second driving component includes a gear fixedly connected to a rotating shaft, a movable part disposed in the first mounting cavity that can move up and down, and a rack fixedly connected to the movable part for meshing with the gear and driving the push wheel to rotate, wherein there are four gears and four racks, and the four gears are respectively connected to the rotating shafts of the four push components.

[0017] Its effect is as follows: the up-and-down movement of the moving part can drive the rack and gear to mesh and transmit power, thereby providing power to the push wheel; when the moving part moves down to drive the rack and gear to mesh and transmit power and drive the push wheel to rotate, it can apply a downward thrust to the irregular pipe fitting, thereby adjusting the placement position of the irregular pipe fitting; when the moving part moves up to drive the rack and gear to mesh and transmit power and drive the push wheel to rotate, it can apply an upward thrust to the irregular pipe fitting, thereby pushing the processed irregular pipe fitting upward, so as to facilitate the removal of the processed irregular pipe fitting.

[0018] Preferably, the second driving component further includes a pushing part disposed in the first and second mounting cavities and capable of moving with the second clamping part. The pushing part is provided with a through groove for limiting the movement of the moving part, and the second mounting cavity is provided with a guide groove for guiding the pushing part. The guide groove is inclined so that the pushing part can tilt upward or tilt downward when it moves.

[0019] Its effect is that by sliding the moving part into the through groove on the pushing part, when the clamping part 2 moves toward the clamping part 1, the clamping part 2 can drive the pushing part to move synchronously, and the pushing part tilts downward under the guidance of the guide groove, and the pushing part drives the moving part to move downward; when the clamping part 2 moves away from the clamping part 1, the pushing part tilts upward under the guidance of the guide groove, and the pushing part drives the moving part to move upward. There is no need to provide additional power electrical components for the up and down movement of the moving part, thus saving maintenance costs.

[0020] Preferably, the movable part is provided with a sliding groove, and a limiting protrusion that is slidably connected to the inner wall of the mounting cavity is fixedly connected to the sliding groove.

[0021] Its effect is that by limiting the sliding connection between the limiting protrusion on the inner wall of the mounting cavity and the sliding groove on the moving part, the moving part can be limited to ensure the stability of the moving part's up and down movement.

[0022] Preferably, the drive wheel is made of rubber material and is elliptical in shape.

[0023] Its effect is that, through the elliptical push wheel made of rubber material, it can avoid scratching the surface of the irregular pipe when the push wheel applies downward thrust to the irregular pipe, and does not contact the push wheel when the irregular pipe is inserted between the four push wheels, thus avoiding the irregular pipe and making it easier to quickly insert the irregular pipe into place.

[0024] Preferably, the clamping mechanism further includes an automatic telescopic part for driving the second clamping part toward or away from the first clamping part, the automatic telescopic part being fixedly connected to the worktable.

[0025] Its effect is that the automatic telescopic unit can provide power for the clamping part two to move toward or away from the clamping part one.

[0026] The beneficial effects of this invention are:

[0027] 1. When the second clamping part moves toward the direction of the first clamping part, it drives the toothed plate to mesh with the toothed ring, thereby driving the container ring to rotate. When the second clamping part moves toward the direction of the first clamping part, it can also drive the pushing part to move downward along the guide groove, so that the pushing part pushes the moving part downward. When the moving part moves downward, it drives the four racks to move downward, so that the four racks mesh with the four gears respectively, thereby driving the rotating shafts in the four pushing parts to rotate counterclockwise. This causes the four rotating shafts to simultaneously drive the four pushing wheels to rotate counterclockwise. The four counterclockwise rotating pushing wheels apply a downward thrust to the small diameter end of the irregular tube. At this time, in conjunction with the rotating container ring, the placement position of the irregular tube can be adjusted.

[0028] 2. After the large-diameter end of the irregular pipe fitting is cut and machined, when the clamping part two moves away from the clamping part one, it drives the toothed plate to mesh with the toothed ring, thereby driving the holding ring to rotate in the opposite direction. When the clamping part two moves away from the clamping part one, it can also drive the pushing part to move upward along the guide groove, so that the pushing part pushes the moving part upward and drives the four racks to move upward. At this time, the four racks mesh with the four gears respectively, so that the rotating shaft in the four pushing parts simultaneously drives the pushing wheel in the four pushing parts to rotate clockwise. The four clockwise rotating pushing wheels apply an upward thrust to the small-diameter end of the irregular pipe fitting, thereby pushing the irregular pipe fitting after cutting and machining upward, so as to facilitate the removal of the irregular pipe fitting after cutting and machining.

[0029] 3. By sliding the moving part into the through groove on the pushing part, when the clamping part 2 moves toward the clamping part 1, the clamping part 2 can drive the pushing part to move synchronously, and the pushing part tilts downward under the guidance of the guide groove, and the pushing part drives the moving part to move downward; when the clamping part 2 moves away from the clamping part 1, the pushing part tilts upward under the guidance of the guide groove, and the pushing part drives the moving part to move upward. There is no need to provide additional power electrical components for the up and down movement of the moving part, saving maintenance costs.

[0030] 4. The elliptical push wheel, made of rubber, prevents scratching the surface of the irregular pipe when it contacts the irregular pipe and applies a downward thrust. Attached Figure Description

[0039] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0040] like Figures 1 to 7 As shown, the metal parts processing apparatus of the present invention includes a worktable 1, a clamping mechanism 2, an adjusting mechanism 3, and a cutting mechanism 4. The clamping mechanism 2 is fixedly installed on the worktable 1, and can clamp and fix the irregularly shaped tubing to be processed. The adjusting mechanism 3 is fixedly installed inside the worktable 1. Before clamping and fixing the irregularly shaped tubing, the clamping mechanism 2 can drive the adjusting mechanism 3 to adjust the placement position of the irregularly shaped tubing, preventing the clamped and fixed irregularly shaped tubing from shifting, thereby avoiding affecting the subsequent cutting and chamfering effect of the irregularly shaped tubing. The cutting mechanism 4 is fixedly installed on the worktable 1, and can cut the clamped and fixed irregularly shaped tubing.

[0041] When processing irregularly shaped pipe fittings, the irregularly shaped pipe fittings are first placed on the adjusting mechanism 3 so that the large-diameter end of the irregularly shaped pipe fittings faces upwards and the small-diameter end faces downwards. Then, the clamping mechanism 2 is started. After the clamping mechanism 2 is started, it first drives the adjusting mechanism 3 to adjust the irregularly shaped pipe fittings. Then, the clamping mechanism 2 clamps and fixes the irregularly shaped pipe fittings. Finally, the cutting mechanism 4 is started to cut the large-diameter end of the irregularly shaped pipe fittings.

[0042] like Figures 1 to 3 As shown, the clamping mechanism 2 includes a first clamping part 21, a second clamping part 22, and an automatic telescopic part 23. The first clamping part 21 is fixedly connected to the top of the worktable 1, and the second clamping part 22 is slidably connected to the top of the worktable 1. Both the first clamping part 21 and the second clamping part 22 have arc-shaped grooves on their adjacent sides, which are adapted to the large-diameter ends of the irregularly shaped pipe fittings. The automatic telescopic part 23 is connected to the top of the worktable 1. The automatic telescopic part 23 is a cylinder, and the telescopic end of the automatic telescopic part 23 faces the second clamping part 22. The second clamping part 22 is connected to the telescopic end of the automatic telescopic part 23.

[0043] When processing irregularly shaped pipe fittings, the irregularly shaped pipe fittings are placed on the adjustment mechanism 3, and the irregularly shaped pipe fittings are located in the arc-shaped groove on the clamping part 21. Then, the automatic telescopic part 23 is activated, and the clamping part 22 is driven to move towards the clamping part 21 through the automatic telescopic part 23. During the movement of the clamping part 22, the adjustment mechanism 3 is driven to operate so that the adjustment mechanism 3 adjusts the placement position of the irregularly shaped pipe fittings until the clamping part 22 contacts the clamping part 21 and forms a clamping and fixing of the irregularly shaped pipe fittings.

[0044] like Figures 1 to 7 As shown, the top of the workbench 1 is provided with mounting cavity 11 and mounting cavity 12, which are connected to each other. The tops of both mounting cavity 11 and mounting cavity 12 are open. The adjustment mechanism 3 includes a holding ring 31, a driving component 1, a pushing component, and a driving component 2. The holding ring 31 is rotatably connected to the top of the workbench 1 and is located above mounting cavity 11. A tapered hole is provided on the inner side of the holding ring 31. The tapered hole is coaxially arranged with the arc groove on the clamping part 21. The tapered hole on the holding ring 31 is adapted to the outer side of the tapered transition section on the irregular tube to facilitate the positioning of the irregular tube. A drive component is connected to the clamping part 22 and the holding ring 31. When the clamping part 22 moves towards the clamping part 21, it drives the drive component to rotate, so that the outer side of the tapered transition section fits against the inner wall of the tapered hole on the holding ring 31. A pusher is installed in the mounting cavity 11. The pusher applies a downward pushing force to the small-diameter end of the shaped pipe, so as to adjust the placement position of the shaped pipe and avoid the clamped shaped pipe from shifting, thereby avoiding affecting the subsequent cutting and chamfering effect of the shaped pipe. A drive component is installed in the mounting cavity 11 and the mounting cavity 12, and is connected to the clamping part 22. When the clamping part 22 moves towards the clamping part 21, it drives the drive component to rotate, so that the drive component drives the pusher, thereby providing power for the operation of the pusher.

[0045] When processing irregularly shaped pipe fittings, the irregularly shaped pipe fittings are first placed into the holding ring 31. Then, the clamping part 22 is driven to approach the clamping part 1 21. During this process, the clamping part 22 drives the driving part 1 to run, so that the driving part 1 drives the holding ring 31 to rotate. At the same time, the clamping part 22 drives the driving part 2 to run, so that the pushing part runs and applies a downward thrust to the irregularly shaped pipe fittings, adjusting the placement position of the irregularly shaped pipe fittings and preventing the irregularly shaped pipe fittings from shifting after being clamped and fixed, thereby avoiding affecting the subsequent cutting and chamfering effect of the irregularly shaped pipe fittings.

[0046] Continue to refer to Figures 1 to 7 As shown, the drive component includes a toothed plate 32 and a toothed ring 33. The toothed plate 32 is fixedly connected to the clamping part 22, and the toothed ring 33 is fixedly connected to the outside of the holding ring 31. The toothed plate 32 and the toothed ring 33 are engaged. When the clamping part 22 moves toward the clamping part 21, it can drive the toothed plate 32 to move, so that the toothed plate 32 and the toothed ring 33 engage and drive, thereby driving the holding ring 31 to rotate. There is no need to add additional power electrical components to drive the holding ring 31 to rotate, saving maintenance and manufacturing costs.

[0047] Continue to refer to Figures 1 to 7 As shown, four pushers are arranged in a ring. Each pusher includes a fixed base 34, a rotating shaft 35, and a pusher wheel 36. The fixed base 34 is fixedly connected to the inner wall of the mounting cavity 11, the rotating shaft 35 is rotatably connected to the fixed base 34, and the pusher wheel 36 is fixedly connected to the rotating shaft 35. The pusher wheel 36 is made of rubber and is elliptical in shape. After the shaped tube is inserted into the holding ring 31, the small-diameter end of the shaped tube can be inserted between the four pushers 36, and the small-diameter end of the shaped tube contacts the four pushers 36. When the clamping part 22 moves, it drives the driving part 2 to run, so that the driving part 2 drives the rotating shaft 35 in the four pushers to rotate synchronously and in the same direction, and drives the four pushers 36 to rotate synchronously and in the same direction. The four synchronously rotating push wheels 36 can apply an upward or downward thrust to the irregular pipe fitting; when the four synchronously rotating push wheels 36 apply a downward thrust to the irregular pipe fitting, the placement position of the irregular pipe fitting can be adjusted to prevent the clamped irregular pipe fitting from shifting; when the four synchronously rotating push wheels 36 apply an upward thrust to the irregular pipe fitting, the processed irregular pipe fitting can be pushed upward to facilitate the removal of the irregular pipe fitting from the processing device.

[0048] When the clamping part 22 moves toward the clamping part 21 and drives the driving member 2 to run, the driving member 2 drives the rotating shafts 35 in the four pushers to rotate counterclockwise synchronously, so that the four rotating shafts 35 drive the four push wheels 36 to rotate counterclockwise synchronously. The four push wheels 36 that rotate counterclockwise synchronously apply a downward thrust to the small diameter end of the irregular tube. At this time, in conjunction with the rotating holding ring 31, the placement position of the irregular tube can be adjusted, thereby preventing the clamped irregular tube from shifting, and thus preventing the subsequent cutting and chamfering effect of the irregular tube from being affected.

[0049] After the large-diameter end of the irregular-shaped pipe fitting is cut, the clamping part 22 moves away from the clamping part 21 and drives the driving part 2 to run. The driving part 2 drives the rotating shafts 35 in the four pushing parts to rotate clockwise synchronously, so that the four rotating shafts 35 drive the four pushing wheels 36 to rotate clockwise synchronously. The four synchronously rotating pushing wheels 36 apply an upward thrust to the small-diameter end of the irregular-shaped pipe fitting, thereby pushing the irregular-shaped pipe fitting after cutting upward, so as to facilitate the removal of the irregular-shaped pipe fitting after cutting from the holding ring 31.

[0050] Continue to refer to Figures 1 to 7 As shown, a guide groove 13 is provided in the second mounting cavity 12. The guide groove 13 is inclined with the left side lower than the right side. The second driving component includes gears 37, a moving part 38, a rack 39, and a pushing part 310. There are four gears 37 and four racks 39. The four gears 37 are respectively fixedly connected to the rotating shafts 35 on the four pushing parts. A limiting protrusion is fixedly connected in the first mounting cavity 11. The moving part 38 is slidably connected in the first mounting cavity 11. The moving part 38 is provided with a sliding groove. The moving part 38 is slidably connected to the limiting protrusion through the sliding groove, so that the moving part 38 is limited and slidably connected in the first mounting cavity 11. Because the moving part 38 is limited and slidably connected in the first mounting cavity 11, the moving part 38 can only move up and down in the first mounting cavity 11, and the moving part 38 will not rotate when it moves up and down. Four racks 39 are fixedly connected to the top of the moving part 38, and each rack 39 meshes with one of the four gears 37. The pushing part 310 is inserted into the bottom of the clamping part 22. The pushing part 310 has a protrusion that slides within the guide groove 13. When the clamping part 22 moves, it drives the pushing part 310 to move under the guidance of the guide groove 13. The pushing part 310 has a through groove, and the moving part 38 slides within this through groove. When the clamping part 22 moves, it drives the pushing part 310 to tilt upwards or downwards along the guide groove 13. The pushing part 310 provides power for the vertical movement of the moving part 38, eliminating the need for additional power electrical components and saving on maintenance and manufacturing costs.

[0051] When the clamping part 22 moves toward the clamping part 21, the clamping part 22 drives the pushing part 310 to move. The pushing part 310 can be tilted upward or downward along the guide groove 13 by the guide groove 13. The pushing part 310 pushes the moving part 38 downward. When the moving part 38 moves downward, it drives the four racks 39 to move downward, so that the four racks 39 mesh with the four gears 37 respectively. This drives the rotating shafts 35 in the four pushing parts to rotate counterclockwise synchronously, thereby providing power for the pushing wheel 36 to rotate counterclockwise.

[0052] When the clamping part 22 moves away from the clamping part 21, the clamping part 22 drives the pushing part 310 to tilt upward under the guidance of the guide groove 13. The pushing part 310 pushes the moving part 38 upward. When the moving part 38 moves upward, it drives the four racks 39 to move upward, so that the four racks 39 mesh with the four gears 37 respectively. This drives the rotating shafts 35 in the four pushing members to rotate clockwise synchronously, thereby providing power for the clockwise rotation of the pushing wheel 36. When the pushing wheel 36 in the four pushing members rotates clockwise synchronously, the four pushing wheels 36 can apply an upward thrust to the shaped pipe, so as to remove the processed shaped pipe from the processing equipment.

[0053] like Figure 1 and Figure 2 As shown, the cutting mechanism 4 includes a lifting component 41, a drive source 42, and a cutting head 43. The lifting component 41 is fixedly mounted on the worktable 1 and can move up and down. The drive source 42 is fixedly connected to the lifting component 41. The drive source 42 is a servo motor with its output shaft facing downwards. The cutting head 43 is fixedly connected to the output end of the drive source 42. Starting the drive source 42 can drive the cutting head 43 to rotate, and the rotating cutting head 43 can perform cutting processing on the large-diameter end of the irregularly shaped pipe.

[0054] When processing the irregularly shaped pipe fitting, the lifting mechanism 41 is activated, which drives the drive source 42 and the cutting head 43 to move downwards. As the drive source 42 and cutting head 43 move downwards, the drive source 42 is activated, causing the cutting head 43 to rotate. After the cutting head 43 contacts the large-diameter end of the irregularly shaped pipe fitting, the rotating cutting head 43 cuts the large-diameter end of the fitting. After the large-diameter end of the irregularly shaped pipe fitting is cut, the drive source 42 is turned off, causing the cutting head 43 to lose power and stop rotating. Then, the lifting mechanism 41 is activated, causing the drive source 42 and cutting head 43 to move upwards and away from the processed irregularly shaped pipe fitting, facilitating its subsequent removal.

[0055] Working principle: The large-diameter, upward-facing irregular-shaped pipe is placed inside the holding ring 31 so that the tapered transition section of the irregular-shaped pipe is located in the tapered hole on the holding ring 31, and the holding ring 31 provides positioning and support for the irregular-shaped pipe.

[0056] The automatic telescopic unit 23 is activated, and the clamping part 22 is driven to move toward the clamping part 21. When the clamping part 22 moves toward the clamping part 21, it drives the toothed plate 32 to move, so that the toothed plate 32 meshes with the toothed ring 33 for transmission, thereby driving the container ring 31 to rotate and adjusting the placement position of the irregular tube.

[0057] When the clamping part 22 moves toward the clamping part 21, the clamping part 22 also drives the pushing part 310 to tilt downward under the guidance of the guide groove 13. The pushing part 310 pushes the moving part 38 downward. When the moving part 38 moves downward, it drives the four racks 39 to move downward synchronously, so that the four racks 39 mesh with the four gears 37 respectively. This drives the rotating shafts 35 in the four pushing parts to rotate counterclockwise synchronously. The four rotating shafts 35 simultaneously drive the four pushing wheels 36 to rotate counterclockwise synchronously. The four pushing wheels 36 that rotate counterclockwise synchronously apply a downward thrust to the small diameter end of the irregular tube. At this time, in conjunction with the rotating container ring 31, the placement position of the irregular tube can be adjusted.

[0058] After clamping part 22 and clamping part 1 21 clamp and fix the large-diameter end of the irregular pipe fitting, clamping part 22 stops moving. At this time, the entire adjustment mechanism 3 stops operating. The placement position of the irregular pipe fitting has been adjusted and clamped and fixed by clamping part 22 and clamping part 1 21.

[0059] Start the lifting component 41, which drives the drive source 42 and the cutting head 43 to move downward. When the drive source 42 and the cutting head 43 move downward, start the drive source 42, which drives the cutting head 43 to rotate stably. After the rotating cutting head 43 contacts the large-diameter end of the irregular pipe, the rotating cutting head 43 performs cutting processing on the large-diameter end of the irregular pipe.

[0060] After the large-diameter end of the irregular pipe is cut and processed, the drive source 42 is turned off so that the cutting head 43 loses power and stops rotating. Then the lifting component 41 is started so that the lifting component 41 drives the drive source 42 and the cutting head 43 to move upward, thereby moving the cutting head 43 away from the processed irregular pipe.

[0061] The automatic telescopic unit 23 is activated, and the clamping part 22 is driven to move away from the clamping part 1 21, so that the clamping part 22 and the clamping part 1 21 release their clamping and fixing of the irregular pipe fitting.

[0062] When clamping part 22 moves away from clamping part 21, clamping part 22 drives pushing part 310 to move. At this time, pushing part 310 moves upward along guide groove 13 under the guidance of guide groove 13. Pushing part 310 pushes moving part 38 upward. When moving part 38 moves upward, it drives four racks 39 to move upward, so that the four racks 39 mesh with four gears 37 respectively, thereby driving the rotating shafts 35 in the four pushing parts to rotate clockwise synchronously. When the rotating shafts 35 in the four pushing parts rotate clockwise synchronously, the four rotating shafts 35 simultaneously drive the four pushing wheels 36 to rotate clockwise. The four clockwise rotating pushing wheels 36 apply an upward thrust to the small diameter end of the shaped pipe, thereby pushing the shaped pipe after cutting upward, so as to facilitate the removal of the shaped pipe after cutting from the holding ring 31.
