Description

Technical Field

[0001] This invention relates to a stamping device for producing a reducer housing with a protective mechanism, belonging to the field of metal stamping technology. Background Technology

[0002] Stamping is an important industrial manufacturing method that uses molds and stamping equipment to process sheet metal into parts or components of the required shape. It is widely used in the production of speed reducer housings.

[0003] After stamping, waste and impurities accumulate inside the lower die of the stamping equipment. If these impurities are not cleaned in time, they will seriously affect the accuracy and quality of the stamped metal workpieces. Currently, cleaning the lower die mainly relies on manual cleaning, which is inefficient and requires a large amount of labor costs.

[0004] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a stamping device for producing a reducer housing with a protective mechanism. It solves the problem that in the prior art, after the die of the stamping equipment is stamped, waste and impurities will accumulate inside the lower die. If these impurities are not cleaned in time, they will seriously affect the accuracy and quality of the metal workpieces stamped in the future. At present, cleaning the lower die mainly relies on manual cleaning, which has low cleaning efficiency and requires a large amount of labor costs.

[0006] The technical problem to be solved by the present invention is achieved by the following technical solution: a stamping device for producing a reducer housing with a protective mechanism, including a stamping table, an installation groove is provided on the stamping table, a first cylinder is fixedly connected to the upper surface of the stamping table, a horizontal plate is fixedly connected to the telescopic end of the first cylinder, a positioning rod is fixedly connected to the side of the horizontal plate near the stamping table, and a stamping mechanism capable of stamping metal workpieces is installed on the positioning rod. Mounting brackets are fixedly connected to the inner walls of opposite sides of the mounting slot. Support rods are rotatably mounted on the mounting brackets and pass through the mounting brackets. A rotating block is fixedly connected between the two mounting brackets. Two lower dies are mounted on the rotating block in opposite directions. A moving mechanism is provided on the side of the horizontal plate near the stamping table. The moving mechanism can drive the lower dies to rotate. The mounting slot is equipped with a cleaning component that can clean the lower mold.

[0007] The present invention is further configured such that: the stamping mechanism includes an upper die, a mounting plate is fixedly connected to one end of the positioning rod away from the horizontal plate, the upper die is fixedly mounted on the mounting plate, placement slots are provided on both sides of the rotating block, the lower die can be inserted into the placement slots, multiple fixing bolts are threadedly connected to the rotating block, and fixing holes are provided on both sides of the lower die, the fixing bolts can be inserted into the fixing holes.

[0008] By adopting the above technical solution, the metal workpiece to be stamped is placed on the lower mold located on the upper side. The first cylinder is started to move downward. The first cylinder drives the horizontal plate to move downward. The horizontal plate drives the positioning rod and the mounting plate to move downward. The mounting plate synchronously drives the upper mold to move downward. The downward movement of the upper mold performs the stamping work on the metal workpiece on the lower mold.

[0009] The invention is further configured such that: the moving mechanism includes two connecting rods, the connecting rods are fixedly connected to the side of the horizontal plate near the stamping table, the end of the connecting rod away from the horizontal plate is fixedly connected to a connecting block, a sliding column is fixedly connected to the connecting block, a positioning plate is provided on the sliding column, a positioning groove is opened on the side of the positioning plate near the horizontal plate, the sliding column is slidably connected in the positioning groove, vertical plates are fixedly connected to both ends of the sliding column, and first springs are fixedly connected to the opposite sides of the positioning plate, the end of the first spring away from the positioning plate is fixedly connected to the vertical plate.

[0010] The invention is further configured such that the moving mechanism includes two gears, the gears are fixedly connected to the support rod and the end away from the rotating block, and the positioning plate is fixedly connected to a rack that can mesh with the gears on the side near the gears.

[0011] The invention is further configured such that: the moving mechanism also includes two support blocks, a fixed seat is fixedly connected to the inner wall of the mounting groove, a support block is fixedly connected to the fixed seat, a first slide rail groove is provided on the side of the support block near the positioning plate, the first slide rail groove is vertically arranged, a first moving cavity is provided on one side of the first slide rail groove and communicates therewith, a second moving cavity is provided on the other side of the first slide rail groove and communicates therewith, and a second slide rail groove is provided on the side of the support block near the positioning plate, the second slide rail groove is L-shaped.

[0012] The invention is further configured such that: the moving mechanism also includes a second cylinder, the second cylinder is fixedly connected to the inner walls of opposite sides of the stamping table, and the telescopic end of the second cylinder is fixedly connected to a limit block, the limit block is n-shaped, and the limit block can abut against the rotating block.

[0013] By adopting the above technical solution, when the upper end of the rack abuts against the gear, the second cylinder is activated, causing the limit block to move away from the rotating block, thus releasing the fixation of the rotating block. As the rack continues to move upward, it meshes with the gear and drives the gear to rotate, which in turn drives the support rod and the rotating block to rotate synchronously. This causes the lower die to rotate around the axis of the support rod, resulting in the two lower dies flipping during rotation. After each stamping operation, the two lower dies flip once, allowing them to sequentially face upward for stamping. During this process, the lower dies also sequentially reverse downward. This downward flipping of the lower dies allows waste or impurities inside the lower die to be poured into the mounting groove, thus cleaning the lower die and preventing the accumulation of impurities. This prevents impurities from adversely affecting the precision and quality of the subsequently stamped metal workpieces, providing protection for the die. Furthermore, manual cleaning is not required, making the operation simple, efficient, and labor-saving, thereby improving the stamping effect of the stamping device and enhancing its practicality.

[0014] The present invention is further configured such that: the cleaning component includes an air tank, two air tanks are respectively fixedly installed on opposite sides of the stamping table, an air pipe one connected to the side of the air tank near the horizontal plate is fixedly connected to it, an air pipe two connected to the side of the air tank is fixedly connected to it, a sliding block slidably connected inside the air tank is fixedly connected to the lower end of the air tank, and a sealing plug is fixedly connected to the side of the sliding block away from the connecting rod, and the sealing plug slidably connected inside the air tank.

[0015] The invention is further configured such that: the cleaning component also includes a first fixing block fixedly connected to the inner wall of one side of the mounting groove, a fixing frame fixedly connected to the first fixing block, a plurality of horizontal tubes fixedly connected inside the fixing frame, and a nozzle communicating with the horizontal tubes fixedly installed on the horizontal tubes.

[0016] By adopting the above technical solution, when the first cylinder is started and drives the horizontal plate to move downward, the horizontal plate drives the connecting rod to move downward. The connecting rod drives the sliding block and sealing plug to slide downward. The sliding block and sealing plug force the air located below the sealing plug in the air tank into the horizontal pipe through the second air pipe and the corrugated hose, and then blow the air upward through the nozzle. The nozzle blows the air upward into the lower mold, thereby cleaning the lower mold facing downward, further blowing out impurities in the lower mold, thus improving the cleaning effect of the lower mold, ensuring the production quality of the reducer housing, and eliminating the need for manual cleaning. Furthermore, the air blowing cleaning of the lower mold in this solution does not require additional electricity, making it more efficient and energy-saving, thereby improving the economy of the stamping device.

[0017] The invention is further configured such that: a fixed cylinder is slidably sleeved on the positioning rod, an installation rod is fixedly connected to the fixed cylinder, the lower end of the installation rod is a spherical surface, a positioning bolt is threadedly connected to the fixed cylinder, and the end of the positioning bolt penetrates into the fixed cylinder and can abut against the positioning rod.

[0018] The invention is further configured such that: a connecting cavity is formed through one side of the stamping table; a rotating groove is formed on the inner wall of the side of the stamping table away from the connecting cavity; a limiting shaft is rotatably connected between the inner walls of opposite sides of the rotating groove; a collecting plate is fixedly connected to the limiting shaft; multiple vibrating blocks are fixedly connected to the inner wall of the collecting plate; the lower end of the mounting rod can abut against the inner wall of the collecting plate; the lower end of the mounting rod can slide against the vibrating blocks; a mounting rod is fixedly connected to the bottom wall of the stamping table; a sliding rod is slidably connected inside the mounting rod; a connecting spring is fixedly connected between the lower end of the sliding rod and the bottom wall of the stamping table; a mounting shell is fixedly connected to the upper end of the sliding rod; a rotating wheel is rotatably connected to the mounting shell; and the rotating wheel abuts against the lower surface of the collecting plate.

[0019] By adopting the above technical solution, the positioning rod moves downward, which also drives the mounting rod downward. During the downward movement of the mounting rod, it abuts against the collecting plate and pushes the collecting plate to rotate around the limiting shaft. During this process, the collecting plate tilts, and the collecting plate also pushes the rotating wheel downward. This causes the connecting spring to be squeezed and deformed through the sliding rod. As the mounting rod continues to move downward, its lower end abuts against the vibrating block. The interaction between the vibrating block and the connecting spring causes the collecting plate to vibrate as it rotates around the limiting shaft. This causes some accumulated debris on the collecting plate to fall off the outside of the stamping table as the tilted and vibrating collecting plate tilts, thus cleaning the collecting plate. This avoids excessive accumulation of impurities or scraps in the mounting groove, saving manpower and increasing energy efficiency, thereby improving the stamping efficiency of the stamping device on metal.

[0020] The beneficial effects of this invention are as follows: starting the first cylinder can drive the horizontal plate to move downwards, and the downward movement of the horizontal plate can simultaneously drive the connecting rod to move downwards. The connecting rod can drive the connecting block and the sliding column to move downwards. Because the positioning groove is slidably connected to the sliding column and the upper surface of the positioning plate is slidably connected to the lower surface of the connecting block, the positioning plate can only move left and right, so that the positioning plate will not rotate or disengage from the sliding column. Then, the downward movement of the connecting rod can simultaneously drive the positioning plate to move downwards. During the downward movement of the positioning plate, the moving column is driven to slide into the first slide rail groove. When the moving column slides into the first slide rail groove, the rack and gear are in a misaligned state. In the initial state, the limiting block can abut against the rotating block. The adjacent sides of the two vertical plates of the limiting block abut against the upper and lower surfaces of the rotating block. The abutment between the limiting block and the rotating block has a fixing effect on the rotating block, so that the rotating block cannot rotate around the axis of the support rod.Initially, the two first springs position and support the positioning plate, allowing the moving column to slide into the first slide rail groove without the first springs being under stress. As the connecting rod continues to move downward, the moving column slides into the first moving cavity, pushing the support block away from the rotating block. This, in turn, drives the rack further away from the gear, causing the rack and gear to misalign. During the sliding process of the moving column in the first moving cavity, the first springs are stretched or compressed. As the moving column continues to slide downward to the bottom of the first moving cavity, the release force of the first springs causes the moving column to slide into the transverse groove of the second slide rail groove. At this time, the upper mold has moved downward to abut against the lower mold to complete the stamping of the metal material. Then, the first cylinder drives the transverse plate upward, which in turn drives the moving column upward into the second moving cavity. During the movement of the moving column into the second moving cavity, the positioning plate moves closer to the rotating block and aligns the rack and gear. After the rack and gear are aligned, the rack moves upward with the moving column. The upper end of the rack engages with the gear. When the upper end of the rack engages with the gear, the second cylinder activates, causing the limit block to move away from the rotating block, releasing the fixing of the rotating block. As the rack continues to move upward, it meshes with the gear and drives the gear to rotate, which in turn drives the support rod and the rotating block to rotate synchronously. This causes the lower die to rotate around the axis of the support rod, resulting in the two lower dies flipping during rotation. After each stamping cycle, the two lower dies flip once, allowing them to sequentially face upward for stamping. During this process, the lower dies also sequentially reverse downward. This downward flipping of the lower dies allows waste or impurities inside the lower die to be dumped into the mounting groove, thus cleaning the lower die and preventing the accumulation of impurities. This prevents impurities from adversely affecting the precision and quality of subsequently stamped metal workpieces, providing protection for the die. Furthermore, it eliminates the need for manual cleaning, making operation simple, efficient, and labor-saving, thereby improving the stamping effect of the stamping device and enhancing its practicality.

[0023] To facilitate a clear understanding of the technical means, inventive features, objectives, and effects of this invention, the following detailed description is provided. Figures 1 to 9 The invention will be further illustrated as shown.

[0024] like Figures 1 to 4 As shown, the present invention is a stamping device for producing a reducer housing with a protective mechanism, including a stamping table 1, a mounting groove 2 on the stamping table 1, a first cylinder 3 fixedly connected to the upper surface of the stamping table 1, a horizontal plate 4 fixedly connected to the telescopic end of the first cylinder 3, a positioning rod 5 fixedly connected to the side of the horizontal plate 4 near the stamping table 1, and a stamping mechanism capable of stamping metal workpieces installed on the positioning rod 5. Mounting brackets 11 are fixedly connected to the inner walls of opposite sides of mounting slot 2. Support rods 31 are rotatably mounted on mounting brackets 11 and pass through mounting brackets 11. Rotating blocks 35 are fixedly connected between the two mounting brackets 11. Two lower molds 30 are mounted on rotating blocks 35 in opposite positions. A moving mechanism is provided on the side of the horizontal plate 4 near the stamping table 1. The moving mechanism can drive the lower molds 30 to rotate. The mounting slot 2 is equipped with a cleaning component that can clean the lower mold 30.

[0025] like Figures 1 to 3 As shown, the stamping mechanism includes an upper die 9. The end of the positioning rod 5 away from the horizontal plate 4 is fixedly connected to a mounting plate 10. The upper die 9 is fixedly mounted on the mounting plate 10 by bolts. The upper die 9 is adapted to the lower die 30. The rotating block 35 has placement slots 50 on both sides. The lower die 30 can be inserted into the placement slots 50. The rotating block 35 is threaded with multiple fixing bolts 34. The ends of the fixing bolts 34 can penetrate into the placement slots 50. The lower die 30 has fixing holes 36 on both sides. The fixing bolts 34 can be inserted into the fixing holes 36.

[0026] In this scheme, the metal workpiece to be stamped is placed on the lower mold 30 located on the upper side. The first cylinder 3 is started to move downward. The first cylinder 3 drives the horizontal plate 4 to move downward. The horizontal plate 4 drives the positioning rod 5 and the mounting plate 10 to move downward. The mounting plate 10 simultaneously drives the upper mold 9 to move downward. The upper mold 9 moves downward to perform stamping work on the metal workpiece on the lower mold 30.

[0027] like Figures 1 to 6 As shown, the moving mechanism includes two connecting rods 21. The connecting rods 21 are fixedly connected to the side of the horizontal plate 4 near the stamping table 1. The end of the connecting rod 21 away from the horizontal plate 4 is fixedly connected to a connecting block 22. A sliding column 23 is fixedly connected to the connecting block 22. A positioning plate 27 is provided on the sliding column 23. A positioning groove 25 is opened on the side of the positioning plate 27 near the horizontal plate 4. The positioning groove 25 extends out of the left and right sides of the positioning plate 27. The sliding column 23 is slidably connected in the positioning groove 25. Both ends of the sliding column 23 extend out of the outer side of the positioning plate 27. A vertical plate 24 is fixedly connected to both ends of the sliding column 23. A first spring 26 is fixedly connected to the opposite sides of the positioning plate 27. The end of the first spring 26 away from the positioning plate 27 is fixedly connected to the vertical plate 24. The extension path of the vertical plate 24 is consistent with the sliding path of the sliding column 23.

[0028] The moving mechanism also includes two gears 29, which are fixedly connected to the support rod 31 and the end away from the rotating block 35. A rack 28 that can mesh with the gear 29 is fixedly connected to the side of the positioning plate 27 near the gear 29.

[0029] In this design, gear 29 is a spur gear.

[0030] The moving mechanism also includes two support blocks 32. A fixed seat is fixedly connected to the inner wall of the mounting groove 2, and a support block 32 is fixedly connected to the fixed seat. A first slide rail groove 37 is formed on the side of the support block 32 near the positioning plate 27. The first slide rail groove 37 extends beyond the upper surface of the support block 32 and is vertically arranged. A first moving cavity 33 communicating with the first slide rail groove 37 is formed on one side, and a second moving cavity 39 communicating with the first slide rail groove 37 is formed on the other side. Both the first moving cavity 33 and the second moving cavity 39 extend beyond the surface of the support block 32 near the positioning plate 27. A second slide rail groove 53 is provided on one side of the positioning plate 27. The second slide rail groove 53 is L-shaped. The vertical groove of the second slide rail groove 53 is on the same vertical line as the first slide rail groove 37. The horizontal groove of the second slide rail groove 53 is perpendicular to the first slide rail groove 37. A movable column 38 that can be inserted into the first slide rail groove 37 is fixedly connected to the side of the positioning plate 27 near the support block 32. The movable column 38 can slide and connect with the first movable cavity 33, the second slide rail groove 53 and the second movable cavity 39. The upper surface of the positioning plate 27 abuts against the lower surface of the connecting block 22. The first movable cavity 33 is connected to the lower end of the first slide rail groove 37.

[0031] like Figures 1 to 6 As shown, the moving mechanism also includes a second cylinder 52, which is fixedly connected to the inner walls of opposite sides of the stamping table 1. The telescopic end of the second cylinder 52 is fixedly connected to a limit block 51, which is n-shaped and can abut against the rotating block 35.

[0032] In this design, starting the first cylinder 3 causes the horizontal plate 4 to move downwards. The downward movement of the horizontal plate 4 simultaneously moves the connecting rod 21 downwards. The connecting rod 21 then moves the connecting block 22 and the sliding column 23 downwards. Because the positioning groove 25 is slidably connected to the sliding column 23 and the upper surface of the positioning plate 27 is slidably connected to the lower surface of the connecting block 22, the positioning plate 27 can only move left and right, preventing it from rotating or disengaging from the sliding column 23. Consequently, the downward movement of the connecting rod 21 simultaneously moves the positioning plate 27 downwards. As the positioning plate 27 moves downward, it drives the moving column 38 to slide into the first slide rail groove 37. When the moving column 38 slides into the first slide rail groove 37, the rack 28 and the gear 29 are in a misaligned state. In the initial state, the limiting block 51 can abut against the rotating block 35. The adjacent sides of the two vertical plates of the limiting block 51 abut against the upper and lower surfaces of the rotating block 35. The abutment between the limiting block 51 and the rotating block 35 has a fixing effect on the rotating block 35, so that the rotating block 35 cannot rotate around the axis of the support rod 31.In the initial state, the two first springs 26 provide positioning and support for the positioning plate 27, allowing the moving column 38 to slide into the first slide rail groove 37 without the first springs 26 being under stress. As the connecting rod 21 continues to move downward, it drives the moving column 38 to slide into the first moving cavity 33, and pushes the support block 32 to move away from the rotating block 35. This, in turn, drives the rack 28 to move further away from the gear 29. During this process, the rack 28 and the gear 29 are misaligned. As the moving column 38 slides in the first moving cavity 33, it causes the first springs 26 to be stretched or compressed. When the 38 continues to slide downwards to the lowest end of the first moving cavity 33, under the action of the release force of the first spring 26, the moving column 38 slides into the horizontal groove of the second slide rail groove 53. At this time, the upper mold 9 has moved downwards to abut against the lower mold 30 to complete the stamping of the metal material. At this time, the first cylinder 3 drives the horizontal plate 4 to move upwards, and then simultaneously drives the moving column 38 to move upwards into the second moving cavity 39. During the process of the moving column 38 moving into the second moving cavity 39, it drives the positioning plate 27 to move closer to the rotating block 35 and drives the rack 28 to align with the gear 29. When the rack 28 and the gear 29 are aligned, the rack 28... 8. As the moving column 38 moves upward, the upper end of the rack 28 abuts against the gear 29. When the upper end of the rack 28 abuts against the gear 29, the second cylinder 52 is activated, causing the limit block 51 to move away from the rotating block 35, thus releasing the fixation of the rotating block 35. As the rack 28 continues to move upward, it meshes with the gear 29 and drives the gear 29 to rotate, thereby synchronously driving the support rod 31 and the rotating block 35 to rotate. This, in turn, causes the lower die 30 to rotate around the axis of the support rod 31, causing the two lower dies 30 to flip during rotation. After each stamping is completed, the two lower dies flip. Each rotation causes the two lower dies 30 to face upwards sequentially for stamping. Simultaneously, the lower dies 30 also rotate downwards sequentially, allowing waste or impurities to be dumped into the mounting groove 2. This cleaning process prevents impurities from accumulating and negatively impacting the precision and quality of subsequently stamped metal workpieces, thus protecting the dies. Furthermore, it eliminates the need for manual cleaning, making operation simple, efficient, and labor-saving, thereby improving the stamping effect and practicality of the stamping device.

[0033] like Figures 3 to 8As shown, the cleaning assembly includes an air tank 12. Two air tanks 12 are fixedly installed on opposite sides of the stamping table 1. An air pipe 16 connected to the side of the air tank 12 closest to the horizontal plate 4 is fixedly connected to it. An air pipe 19 connected to the side of the air tank 12 is fixedly connected to it. A sliding block 18 is fixedly connected to the lower end of the air tank 12 and slidably connected inside the air tank 12. A sealing plug 17 is fixedly connected to the side of the sliding block 18 away from the connecting rod 21 and slidably connected inside the air tank 12.

[0034] The cleaning assembly also includes a first fixing block 20 fixedly connected to the inner wall of one side of the mounting groove 2. A fixing frame 13 is fixedly connected to the first fixing block 20. Multiple horizontal tubes 14 are fixedly connected inside the fixing frame 13. One end of the horizontal tube 14 is closed, and the other end of the horizontal tube 14 passes through the fixing frame 13. A corrugated hose is fixedly connected between the other end of the horizontal tube 14 and the second air pipe 19. A nozzle 15 communicating with the horizontal tube 14 is fixedly installed on the horizontal tube 14. The nozzle 15 is located on the lower side of the lower mold 30.

[0035] In this scheme, when the first cylinder 3 is activated and the horizontal plate 4 moves downward, the horizontal plate 4 moves the connecting rod 21 downward. The connecting rod 21 moves the sliding block 18 and the sealing plug 17 downward. The sliding block 18 and the sealing plug 17 pressurize the air in the air tank 12 located below the sealing plug 17 through the air pipe 19 and the corrugated hose into the horizontal pipe 14, and blow it upward through the nozzle 15. The nozzle 15 blows the air upward into the lower mold 30, thereby cleaning the lower mold 30 facing downward, further blowing out the impurities in the lower mold 30, thereby improving the cleaning effect of the lower mold 30, ensuring the production quality of the reducer housing, and eliminating the need for manual cleaning. Furthermore, the air blowing cleaning of the lower mold 30 in this scheme does not require additional electricity, making it more efficient and energy-saving, thereby improving the economy of the stamping device.

[0036] In this scheme, when the horizontal plate 4 drives the rack 28 to move upward to the upper inclined position of the second moving cavity 39, the moving column 38 gradually slides towards the direction of the first slide rail groove 37. At this time, the rack 28 not only moves upward, but also moves away from the rotating block 35, thereby driving the rack 28 to gradually disengage from the gear 29. When the rack 28 disengages from the gear 29, the rotating block 35 is in a horizontal state. At the same time, the second cylinder 52 drives the limiting block 51 to move towards the rotating block 35 and abut against the rotating block 35, thereby repositioning and supporting the rotating block 35, thereby protecting and fixing the rotating block 35, preventing the rotating block 35 from rotating arbitrarily, so that the lower mold 30 on the rotating block 35 can withstand the punching pressure of the upper mold 9.

[0037] like Figure 3As shown, a fixed cylinder 6 is slidably sleeved on the positioning rod 5, and an installation rod 7 is fixedly connected to the fixed cylinder 6. The lower end of the installation rod 7 is a spherical surface. A positioning bolt 8 is threadedly connected to the fixed cylinder 6. The end of the positioning bolt 8 penetrates into the fixed cylinder 6 and can abut against the positioning rod 5.

[0038] like Figures 6 to 8 As shown, a connecting cavity 48 is provided through one side of the stamping table 1. A rotating groove 47 is provided on the inner wall of the side of the stamping table 1 away from the connecting cavity 48. A limiting shaft 42 is rotatably connected between the inner walls of opposite sides of the rotating groove 47. A collecting plate 41 is fixedly connected to the limiting shaft 42. Multiple vibrating blocks 40 are fixedly connected to the inner wall of the collecting plate 41. The lower end of the mounting rod 7 can abut against the inner wall of the collecting plate 41. The lower end of the mounting rod 7 can slide with the vibrating blocks 40. The bottom wall of the stamping table 1 is fixed. A mounting sleeve 43 is fixedly connected, and a sliding rod 44 is slidably connected inside the mounting sleeve 43. A connecting spring 49 is fixedly connected between the lower end of the sliding rod 44 and the bottom wall of the stamping table 1. The upper end of the sliding rod 44 extends out of the upper surface of the mounting sleeve 43. A mounting shell 45 is fixedly connected to the upper end of the sliding rod 44. A rotating wheel 46 is rotatably connected to the mounting shell 45. The rotating wheel 46 abuts against the lower surface of the collecting plate 41. The collecting plate 41 is slidably connected to the inner walls of the opposite sides of the stamping table 1.

[0039] As the positioning rod 5 moves downward, it also drives the mounting rod 7 downward. During this downward movement, the mounting rod 7 comes into contact with the collecting plate 41 and pushes the collecting plate 41 to rotate around the limiting shaft 42. This causes the collecting plate 41 to tilt, and the collecting plate 41 also pushes the rotating wheel 46 downward. This causes the connecting spring 49 to be squeezed by the sliding rod 44, resulting in the deformation of the connecting spring 49. As the mounting rod 7 continues to move downward, its lower end comes into contact with the vibrating block 40. The interaction between the vibrating block 40 and the connecting spring 49 causes the collecting plate 41 to vibrate as it rotates around the limiting shaft 42. This causes some accumulated debris on the collecting plate 41 to fall off the outside of the stamping table 1 as the collecting plate 41 tilts and vibrates, thus cleaning the collecting plate 41. This prevents excessive accumulation of impurities or scraps in the mounting groove 2, saving manpower and increasing energy efficiency, thereby improving the stamping efficiency of the stamping device.
