Description

Technical Field

[0001] This application relates to the technical field of metal tube processing equipment, and in particular to a cutting device for metal tube processing. Background Technology

[0002] During aluminum tube production, aluminum rods are placed into an aluminum tube extrusion press. A hydraulic cylinder pushes the aluminum rod inside the extrusion cylinder towards the die. As the hydraulic cylinder operates, the aluminum rod enters the die and is extruded into an aluminum tube. The extruded aluminum tube enters a cooling tank. After cooling, the aluminum tube is clamped by a clamping plate, and then a cutting assembly cuts it. Since the aluminum tube is constantly moving forward, the cutting device must also move with the tube. After the cutting assembly moves to the designated position, it cuts the aluminum tube. After cutting, the cutting assembly moves in the opposite direction to the designated position and then moves forward synchronously with the extruded aluminum tube. Repeating the above steps allows for continuous cutting of the aluminum tube.

[0003] For example, Chinese patent document CN109746505B discloses a metal tube clamping and cutting mechanism, including a frame. A horizontal plate is provided above the top surface of the top plate of the frame. Lower support plates are fixed to the front and rear parts of the bottom surface of the horizontal plate, and the bottom surface of the lower support plates is fixed to the top surface of the top plate of the frame. An upper cutting frame is fixed to the middle of the top plate of the frame, and a cutting lifting cylinder is fixed to the top surface of the middle part of the top plate of the upper cutting frame. A lower... The material cutting channel has an anti-slip guide layer fixed on the top surface of the horizontal plate from the middle to the right. The front and rear of the top surface of the right side of the horizontal plate are fixed with clamping support plates. The outer walls of the two clamping support plates are fixed with clamping cylinders. The push rod of the clamping cylinder passes through the clamping support plate and is fixed with a push plate. The opposing walls of the two push plates are fixed with clamping blocks. The opposing walls of the two clamping blocks are formed with arc grooves. The right side of the metal tube to be processed is in the two arc grooves and clamped between the two clamping blocks. In use, the left side of the metal tube to be processed is pressed against the two sliding plates, and the right side of the metal tube to be processed is pressed against the anti-slip guide layer. Then, by pushing the push rods of all the clamping cylinders and all the auxiliary clamping cylinders, the right side of the metal tube to be processed is placed in the two arc-shaped grooves and clamped between the two clamping blocks, and the left side of the metal tube to be processed is placed in the two auxiliary arc-shaped grooves and clamped between the two auxiliary clamping blocks. Then, by pushing the push rod of the cutting lifting cylinder, and at the same time, the cutting motor runs, causing the cutting wheel to rotate and descend to cut the middle of the metal tube to be processed.

[0004] In the aforementioned related technologies, when cutting a metal tube, the clamping cylinder drives two clamping blocks to move closer together, and the cutting wheel cuts the clamped metal tube. After the metal tube is cut, the clamping cylinder drives the two clamping blocks to move away from each other, and then the subsequent metal tube continues to move forward. While moving, it pushes the cut metal tube to detach. However, during the cutting process, a large amount of metal chips fall onto the worktable, and the subsequent metal tube will scratch the surface of the metal tube as it moves on the worktable, affecting the quality of the metal tube. Summary of the Invention

[0005] This application provides a cutting device for processing metal pipes, which aims to solve the problem of scratches on the surface of metal pipes in related technologies.

[0006] The cutting device for metal tube processing provided in this application adopts the following technical solution: A cutting device for processing metal pipes includes a mounting frame, a worktable slidably connected to the mounting frame, and a cutting assembly disposed on the worktable. The worktable has a clamping assembly for clamping and fixing the metal pipe. A rotating groove is formed on the worktable, and a support block is disposed within the rotating groove. The support block has a polygonal structure, and its upper surface is flush with the surface of the worktable. Multiple surfaces of the support block have second arc-shaped surfaces for abutting against the surface of the metal pipe. Rotating shafts are fixedly mounted at both ends of the support block and are rotatably connected to the worktable. A moving assembly is disposed on the worktable to drive the rotating shafts and the support block upwards. A support assembly is disposed on the worktable to support the conveyed metal pipe.

[0007] By adopting the above technical solution, the metal tube extruded by the extruder moves to the worktable after passing through the cooling tank. Then, the clamping components on the worktable clamp and fix the metal tube at a designated position. After the metal tube is fixed, the worktable moves simultaneously with the metal tube, allowing the extruder to extrude and cut the metal tube at the same time, improving the cutting efficiency. After the metal tube is cut, the clamping components no longer clamp the metal tube on the worktable, and the worktable moves in the opposite direction. During the movement, the moving components drive the support block to move downwards, and the rotating shaft drives the support block to rotate. As the support block moves downwards, the collision between the support block and the metal tube is reduced during the rotation of the support block. The surface of the support block with metal shavings at the top rotates to the bottom, and the adjacent support block surfaces rotate to the top. Since the surface of the support block with metal shavings rotates downwards, the metal shavings on the support block surface will automatically fall off, achieving the purpose of cleaning the metal shavings on the support block surface. During the reverse movement of the worktable, the contact between the surface of the metal tube and the metal shavings on the worktable is reduced, thereby reducing scratches on the surface of the metal tube.

[0008] Optionally, the moving component includes a mounting block slidably connected to the worktable and a moving cylinder fixed to the worktable, the piston rod of the moving cylinder being fixed to the mounting block, and the rotating shaft being rotatably connected to the mounting block.

[0009] By adopting the above technical solution, after the metal pipe is cut, when the support block needs to be moved down, the moving cylinder drives the mounting plate to move down, and the mounting block will drive the support block to move up and down, thus making it more convenient to adjust the position of the support block.

[0010] Optionally, the support assembly includes a support shaft fixed to the worktable and a support roller rotatably connected to the support shaft, wherein the support roller is provided with a third arc-shaped surface for abutting against the surface of the metal tube.

[0011] By adopting the above technical solution, during the process of the mounting block driving the support block to move downward, the metal tube extruded by the extruder will abut against the support roller. During the reverse movement of the worktable, the metal tube can be supported. Under the action of the third arc surface, the extruded metal tube can be limited, and the metal tube can be made more stable when moving on the support roller.

[0012] Optionally, the support block is provided with an installation component and an elastic mounting piece. The elastic mounting piece is fixed to the support block by the installation component and abuts against the second arc-shaped surface. The support block is provided with an installation groove that communicates with the second arc-shaped surface. A shaking component for shaking the elastic mounting piece is provided in the installation groove.

[0013] By adopting the above technical solution, since an elastic mounting plate is provided in the second arc-shaped surface, the metal chips formed during the cutting process of the metal tube will fall onto the elastic mounting plate. When the elastic mounting plate with metal chips rotates to the bottom, the shaking component pulls the elastic mounting plate to shake. During the shaking process, the metal chips on the elastic mounting plate are further cleaned, thereby improving the cleaning effect of metal chips on the support block.

[0014] Optionally, the shaking assembly includes a shaking plate fixed to the bottom of the elastic mounting plate and a shaking spring fixed to the shaking plate. One end of the shaking spring is fixed to the shaking plate and the other end is fixed to the support block. The worktable is provided with a pushing assembly for pushing the shaking plate to move closer to the center of the support block.

[0015] By adopting the above technical solution, during the downward rotation of the support block, the pushing component will drive the shaking plate to move closer to the center of the support block. During the movement, the elastic mounting plate in the second arc surface will be stretched, and the shaking spring will be compressed. When the pushing component and the shaking plate are not aligned, the compressed shaking spring will reset. During the reset process of the shaking plate, the elastic mounting plate will shake, and the metal shavings on the second arc surface will be shaken off, thereby facilitating the cleaning of metal shavings on the elastic mounting plate.

[0016] Optionally, the pushing assembly includes a pushing rod fixed to the shaking plate, a pushing ring fixed to the worktable, a pushing block fixed to the inner side of the pushing ring, and an arc-shaped pushing surface disposed on the pushing block. The pushing rod includes a connecting part and a pushing part, which are arranged vertically. The pushing part is disposed inside the pushing ring and is used to abut against the pushing surface on the pushing block.

[0017] By adopting the above technical solution, when it is necessary to shake the elastic mounting piece within the second arc-shaped surface, the rotating shaft drives the support block to rotate. During the rotation of the support block, the shaking plate will rotate. The pushing part on the shaking plate will move from the lowest point of the pushing surface to the highest point of the pushing surface. During the movement of the pushing part, it will push the shaking plate towards the center of the support block. At the same time, the shaking spring is compressed and the elastic mounting piece is stretched. When the pushing part moves from the highest point of the pushing surface to the lowest point of the pushing surface, the compressed shaking spring pushes the shaking plate to reset, and the stretched elastic mounting piece restores its deformation. During the process of restoring deformation, a shaking will occur, thereby achieving the purpose of facilitating the shaking of the elastic mounting piece.

[0018] Optionally, a cleaning plate is provided on the workbench, and two cleaning plates are provided. The two cleaning plates are respectively fixed at both ends of the workbench, and a discharge port is provided on the mounting frame, which is located between the two cleaning plates.

[0019] By adopting the above technical solution, during the rotation of the support block, the metal shavings on the elastic mounting plate will fall below the worktable. Then, during the reciprocating movement of the worktable, the cleaning plate will push the fallen metal shavings towards the discharge port, thereby achieving automatic cleaning of the fallen metal shavings.

[0020] Optionally, two push rods, two push rings, and two push blocks are provided, with the two push rods, push rings, and push blocks located at both ends of the support block.

[0021] By adopting the above technical solution, since there are two push rings, two push rods and two push blocks, it is more stable when pulling the elastic mounting plate.

[0022] Optionally, multiple limiting shafts are fixedly installed on the shaking plate, the multiple limiting shafts are spaced apart along the length direction of the shaking plate, and the limiting shafts are slidably connected to the support block.

[0023] By adopting the above technical solution, during the up-and-down movement of the vibrating plate, the limiting shaft slides on the support block. The setting of the limiting shaft can make the movement of the vibrating plate more stable.

[0024] Optionally, a slider is fixedly installed on the mounting block, and a groove for the slider to slide on the worktable is provided, and the groove is vertically arranged.

[0025] By adopting the above technical solution, the slider moves within the slide groove during the up-and-down movement of the mounting block. Under the action of the slider and the slide groove, the mounting block becomes more stable during the movement.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The surface of the support block with metal shavings at the top will rotate to the bottom, and the surface of the adjacent support block will rotate to the top. Since the surface of the support block with metal shavings will rotate to the bottom, the metal shavings on the surface of the support block will automatically fall off, thus achieving the purpose of cleaning the metal shavings on the surface of the support block. During the reverse movement of the worktable, the contact between the surface of the metal tube and the metal shavings on the worktable can be reduced, thereby reducing scratches on the surface of the metal tube.

[0027] 2. During the process of the mounting block driving the support block to move downward, the metal tube extruded by the extruder will abut against the support roller. During the reverse movement of the worktable, the metal tube can be supported. Under the action of the third arc surface, the extruded metal tube can be limited, making the metal tube more stable when moving on the support roller.

[0028] 3. During the downward rotation of the support block, the pushing component will drive the shaking plate to move closer to the center of the support block. During the movement, the elastic mounting plate in the second arc surface will be stretched, and the shaking spring will be compressed. When the pushing component and the shaking plate are not aligned, the compressed shaking spring will reset. During the reset of the shaking plate, the elastic mounting plate will shake. During the shaking, the metal shavings on the second arc surface will be shaken off, thus facilitating the cleaning of the metal shavings on the elastic mounting plate. Attached Figure Description

[0038] The following combination Figures 1-8 This application will be described in further detail.

[0039] This application discloses a cutting device for processing metal tubes. (Refer to...) Figures 1 to 3A metal tube processing cutting device includes a mounting frame 01, a worktable 02 slidably connected to the mounting frame 01, and a cutting assembly 1 disposed on the worktable 02. A clamping assembly 2 is also disposed on the worktable 02 to clamp the metal tube to be cut. A cutting blade 14 is then used to cut the clamped metal tube. Additionally, a rotating groove 3 is formed on the worktable 02, and a support block 31 is disposed within the rotating groove 3. In this embodiment, the support block 31 is hexagonal and is positioned along the direction of metal tube movement. During movement, the metal tube contacts the surface of the support block 31. A clearance groove 32 is provided on the support block 31. As the cutting blade 14 moves downwards, it moves into the clearance groove 32, at which point the metal tube is completely cut.

[0040] Reference Figures 1 to 3 The cutting assembly 1 includes a mounting plate 11 fixed on the worktable 02, a movable plate 12 slidably connected to the mounting plate 11, a cutting motor (not shown in the figure) fixed on the movable plate 12, and a cutting blade 14 disposed on the output shaft of the cutting motor. The cutting motor drives the cutting blade 14 to rotate. A drive cylinder 15 is fixedly mounted on the mounting plate 11. The piston rod of the drive cylinder 15 is fixed on the movable plate 12. The drive cylinder 15 can drive the cutting cylinder and the cutting blade 14 to move up and down, which facilitates the up and down movement of the cutting blade 14 to cut the metal tube.

[0041] Reference Figures 1 to 3 The support block 31 has rotating shafts 33 fixedly installed at both ends, and the rotating shafts 33 are rotatably connected to the worktable 02. Figure 6 A moving component 4 is provided on the worktable 02. The moving component 4 is used to drive the rotating shaft 33 and the support block 31 to move upward, so that the support block 31 can be rotated by the rotating shaft 33. During the rotation of the support block 31, the surface with metal shavings is rotated to the bottom, and the adjacent surface without metal shavings is rotated to the top. During the downward movement of the support block 31 by the moving component 4, it can prevent the support block 31 from colliding with the surface of the metal tube when rotating. In addition, since the surface of the support block 31 with metal shavings rotates to the bottom, during the subsequent cutting process, the adjacent surface of the support block 31 without metal shavings will rotate to the top. The moving component 4 drives the support block 31 to move upward, so that the upper surface of the support block 31 is flush with the upper surface of the worktable 02. During the subsequent movement of the metal tube, since the metal shavings on the surface of the support block 31 are reduced, the scratches on the surface of the metal tube can be reduced.

[0042] Reference Figures 1 to 3The clamping assembly 2 includes a clamping plate 21 slidably connected to the worktable 02 and a clamping cylinder 22 fixed to the worktable 02. Two clamping plates 21 and two clamping cylinders 22 are provided. The metal tube on the worktable 02 is placed between the two clamping plates 21. The clamping cylinder 22 drives the clamping plate 21 to move, which can clamp the metal tube on the support block 31. At the same time, a first arc-shaped surface 34 is provided on the clamping plate 21, which is used to abut against the surface of the metal tube. A second arc-shaped surface 35 is provided on the support block 31, and the surface of the metal tube abuts against the second arc-shaped surface 35. Since the support block 31 is hexagonal, the second arc-shaped surface 35 is provided on all six surfaces of the support block 31. The first arc-shaped surface 34 can make the two clamping plates 21 fix the metal tube better, and the second arc-shaped surface 35 can limit the movement of the metal tube, thus making the movement of the metal tube more stable.

[0043] Reference Figures 1 to 5 The moving component 4 includes a mounting block 41 slidably connected to the worktable 02 and a moving cylinder 42 fixed to the worktable 02. A slider 36 is fixedly mounted on the mounting block 41, and a sliding groove 37 for the slider 36 to slide is provided on the worktable 02. The sliding groove 37 is set vertically. Two sliders 36 are fixed on each mounting block 41, and each mounting block 41 corresponds to two sliding grooves 37. Then, during the process of the moving cylinder 42 driving the mounting block 41 to move down, the mounting block 41 slides more stably on the worktable 02.

[0044] In this embodiment, the piston rod of the movable cylinder 42 is fixed to the mounting block 41, and the rotating shaft 33 is rotatably connected to the mounting block 41. When the movable cylinder 42 operates, it drives the mounting block 41 and the support block 31 rotatably connected to the mounting block 41 to move up and down. When the support block 31 needs to be rotated, the movable cylinder 42 drives the mounting block 41 to move down, and the mounting block 41 drives the support block 31 to move down. During the rotation of the support block 31, it avoids contact with the metal tube on the workbench 02. After the mounting block 41 and the support block 31 move down, rotating the support block 31... The surface of the metal shaving support block 31 will rotate from the highest point to the lowest point. During the rotation, the metal shavings on the surface of the support block 31 will fall off under the action of gravity, thus achieving the purpose of automatically cleaning the metal shavings on the surface of the support block 31. During the rotation of the support block 31, the adjacent surface without metal shavings will rotate to the highest point. The moving cylinder 42 will drive the mounting block 41 and the support block 31 to move upward, so that the surface that moves to the highest point is in the same plane as the surface of the worktable 02. Then, during the movement of the metal tube, the scratches on the surface of the metal tube by metal shavings can be reduced.

[0045] Reference Figures 1 to 6A support assembly 5 is provided on the worktable 02. The support assembly 5 is used to support the metal tube extruded by the extruder. The support assembly 5 includes a support shaft 51 fixed on the worktable 02 and a support roller 52 rotatably connected to the support shaft 51. The support roller 52 is provided with a third arc-shaped surface 38 for abutting against the surface of the metal tube. During the downward movement of the support block 31, the metal tube extruded by the extruder can be supported by the support roller 52. In this embodiment, two support shafts 51 and support rollers 52 are provided. During the movement of the worktable 02, the metal tube extruded by the extruder can continue to slide on the support roller 52.

[0046] Reference Figures 2 to 5 An installation assembly 6 and an elastic mounting piece 39 are provided on the support block 31. The elastic mounting piece 39 is made of a wear-resistant structure and a high-temperature resistant material. The elastic mounting piece 39 is fixed to the support block 31 by the installation assembly 6. Since the support block 31 has six surfaces, six elastic mounting pieces 39 are also provided in this embodiment. The six elastic mounting pieces 39 are in contact with the second arc-shaped surface 35, which facilitates the metal tube to be placed within the second arc-shaped surface 35. The installation assembly 6 includes a pressure plate 61 that abuts against the elastic mounting piece 39 and a mounting bolt 62 that is threaded onto the pressure plate 61. The pressure plate 61 is fixed to the support block 31 by the mounting bolt 62. Each elastic mounting piece 39 corresponds to two installation assemblies 6, and the two ends of the elastic mounting piece 39 are fixed by the two installation assemblies 6.

[0047] Reference Figures 2 to 5 A shaking component 7 is provided on the support block 31. The shaking component 7 is used to shake the elastic mounting piece 39 in the second arc surface 35, so that the metal chips on the elastic mounting piece 39 can be easily removed. A mounting groove 03 is provided on the support block 31, and the shaking component 7 is disposed in the mounting groove 03. The mounting groove 03 is connected to the second arc surface 35.

[0048] Reference Figures 2 to 5 as well as Figure 7The shaking component 7 includes a shaking plate 71 fixed to the bottom of the elastic mounting piece 39 and a shaking spring 72 fixed to the shaking plate 71. The end of the shaking spring 72 away from the shaking plate 71 is fixed to the support block 31. A pushing component 8 is provided on the worktable 02 to push the shaking plate 71 towards the center of the support block 31. When it is necessary to clean the metal shavings on the elastic mounting piece 39, the pushing component 8 pushes the shaking plate 71 towards the center of the support block 31. At this time, the elastic mounting piece 39 will enter the mounting groove 03, and the corresponding elastic mounting piece 39 will be stretched. After stretching, the pushing component 8 and the shaking plate 71 will separate. The shaking plate 71 will reset under the action of the shaking spring 72. At this time, the elastic mounting piece 39 in the second arc surface 35 will shake, which can remove the metal shavings on the elastic mounting piece 39 and reduce the residue of metal shavings on the elastic mounting piece 39.

[0049] Reference Figures 2 to 5 as well as Figure 7 Multiple limiting shafts 9 are fixedly installed on the shaking plate 71. The multiple limiting shafts 9 are spaced apart along the length direction of the shaking plate 71, and the limiting shafts 9 are slidably connected to the support block 31. During the process of the push rod 81 pushing the shaking plate 71 to move downward, the limiting shafts 9 slide on the support block 31. By setting the limiting shafts 9, the shaking plate 71 can be limited, which can improve the stability of the shaking plate 71 when it moves.

[0050] Reference Figures 2 to 5 as well as Figure 7 The pushing assembly 8 includes a pushing rod 81 fixed on the vibrating plate 71, a pushing ring 82 fixed on the worktable 02, a pushing block 83 fixed on the inner side of the pushing ring 82, and an arc-shaped pushing surface 84 provided on the pushing block 83. The pushing rod 81 includes a connecting part 811 and a pushing part 812. The connecting part 811 and the pushing part 812 are arranged vertically. Under the action of the connecting part 811 and the pushing part 812, the pushing rod 81 has an L-shaped structure. The connecting part 811 is fixed to the end of the vibrating plate 71. The pushing part 812 is provided inside the pushing ring 82 and is used to abut against the pushing surface 84 on the pushing block 83. Under the action of the arc-shaped pushing surface 84, the pushing block 83 has a highest point and a lowest point. The lowest point is connected to the inner side of the pushing ring 82.

[0051] During the rotation of the support block 31 driven by the rotating shaft 33, the uppermost push rod 81 rotates downwards. During the downward rotation, it moves from the lowest point to the highest point on the push surface 84. The push surface 84 pushes the push rod 81 towards the center of the support block 31. At this time, it pulls the elastic mounting plate 11 in the second arc surface 35 towards the center of the support block 31, causing the elastic mounting piece 39 to deform to a certain extent. When the push part 812 abuts against the highest point on the push surface 84, the elastic mounting plate 11 is stretched to the maximum extent. Then, as the support block 31 continues to rotate, the push rod 81 moves from the highest point to the lowest point on the push surface 84, and the elastic mounting piece 39 returns to its original shape. When the rotation speed of the support block 31 increases, the stretched elastic mounting piece 39 will vibrate. During the vibration, it is easier for metal shavings on the elastic mounting piece 39 to fall off, thus facilitating the cleaning of metal shavings.

[0052] Two push rods 81, two push rings 82, and two push blocks 83 are provided. The two push rods 81, two push rings 82, and two push blocks 83 are located at both ends of the support block 31. During the rotation of the support block 31 driven by the rotating shaft 33, the elastic mounting plate 39 on the support block 31 will be stretched more evenly, and finally the vibration effect of the elastic mounting plate 39 will be better.

[0053] Reference Figures 2 to 5 as well as Figure 8 A cleaning plate 91 is installed on the workbench 02. Two cleaning plates 91 are installed and fixed at both ends of the workbench 02. A discharge port 92 is opened on the mounting frame 01 and is located between the two cleaning plates 91. When the support block 31 rotates, the metal shavings on the surface of the elastic mounting piece 39 will fall between the two cleaning plates 91. Then, when the workbench 02 moves back and forth, it will drive the cleaning plates 91 to move. During the movement of the cleaning plates 91, they will push the falling metal shavings into the discharge port 92, thus facilitating the cleaning and collection of the falling metal shavings.

[0054] A drive motor is fixedly mounted on the mounting block 41. The output shaft of the drive motor is fixedly connected to the rotating shaft 33. In this embodiment, the drive motor is set as a servo motor. When the support block 31 needs to rotate, the drive motor drives the rotating shaft 33 to rotate. During the rotation of the rotating shaft 33, the support block 31 will rotate. At this time, it is convenient to adjust the position of the support block 31.

[0055] The implementation principle of the metal tube processing cutting device in this application embodiment is as follows: When cutting the metal tube, the upper surface of the support block 31 and the upper surface of the worktable 02 are on the same plane. The extruder extrudes the metal tube, and the extruded metal tube enters the cooling tank. After passing through the cooling tank, the metal tube is on the surface of the support block 31. During the extrusion process, the worktable 02 moves synchronously with the metal tube. When it reaches the specified length, the clamping cylinder 22 drives the clamping plate 21 to move. The two clamping plates 21 clamp and fix the metal tube. Then, the driving cylinder 15 drives the moving plate 12 to move down. At the same time as the moving plate 12 moves down, the cutting motor drives the cutting blade 14 to rotate. At this time, the clamped metal tube is cut. Since the worktable 02 moves synchronously with the metal tube, the metal tube can be extruded and cut at the same time. This cutting method can improve the cutting effect of the metal tube.

[0056] After the metal tube is cut, the clamping cylinder 22 drives the clamping plate 21 to move in the opposite direction. Then, the moving cylinder 42 drives the mounting block 41 to move down. During the downward movement of the mounting block 41, the support block 31 moves down. At the same time, the movement of the worktable 02 on the mounting frame 01 will push the cut metal tube off the worktable 02. The uncut metal tube slides on the support roller 52. After the support block 31 moves down, the drive motor drives the support block 31 to rotate. During the rotation of the support block 31, the surface with metal shavings at the top will rotate downward. Then, the surface adjacent to the support block 31 will rotate to the top. During the downward rotation of the surface with metal shavings, the metal shavings on the surface will detach from the surface of the support block 31. This will facilitate the cleaning of metal shavings from the surface of the support block 31. In addition, since the surface adjacent to the support block 31 without metal shavings rotates to the top, the moving cylinder 42 drives the mounting block 41 and the support block 31 to move up, making the support block 31 flush with the worktable 02. At this time, during the sliding of the metal tube on the support block 31, the scratches on the surface of the metal tube by metal shavings can be reduced.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
