[0010] According to the above technical scheme, the stripping device includes a placing plate, a blanking plate, a door-shaped plate, a contact plate, a short block and a protrusion. The movement of the supporting plate drives the door-shaped plate to move downward, and the downward movement of the door-shaped plate drives the contact plate to move downward. The placing plate is fixedly passed through the top of the lifting plate, the blanking plate is fixedly installed at the bottom of the placing plate, the door-shaped plate slides through the top of the placing plate, and the contact plate is fixedly installed on the top of the door-shaped plate.

The movement of the support plate drives the door-shaped plate to move downward, and the downward movement of the door-shaped plate squeezes the second spring. A second arc surface is provided on a side of the short block close to the protrusion. The second arc surface of the short block contacts the surface of the protrusion during movement. The protrusion is elastic, and vibration is generated through intermittent contact between the short block and the protrusion, so that the contact plate is affected by the vibration when driving the plate to move, thereby improving the demolding effect.

[0012] According to the above technical scheme, the recycling device includes a receiving box, an L-shaped rod, a gripping rod, a T-shaped plate, a lower slide plate, a pressure plate and a triangular plate. The movement of the pressure plate drives the triangular plate to move downward, and the bottom of the pressure plate contacts the bottom of the inner wall of the receiving box during the movement. The receiving box slides through the surface of the processing table, and the L-shaped rod slides through the inner and outer walls of the receiving box. The gripping rod is fixedly installed on the surface of the L-shaped rod, and the T-shaped plate slides through the surface of the L-shaped rod.

A spring four is arranged between the T-shaped plate and the L-shaped rod, and a spring five is arranged between the lower slide plate and the receiving box. The double limit ensures that the receiving box can be taken out by the operator only under correct circumstances, which helps to improve the safety of the operator at work.

[0014] The present invention provides a punching machine for metal manufacturing, which has the following beneficial effects: (1) In the punching machine for metal manufacturing, after being squeezed, the Z-shaped sheet exerts a reaction force on the hollow cylinder under the influence of elastic force. By providing the elastic Z-shaped sheet, the speed at which the telescopic end of the buffer damper moves downward during punching is slowed down, which helps to reduce the wear of the buffer damper and improve the service life of the buffer damper. External air slowly enters between the hollow cylinder and the buffer damper through the air vents on the rotating shaft, and by increasing the resistance encountered by the telescopic end of the buffer damper when it resets upward, the rebound force of the buffer damper is reduced, thereby improving the buffer shock absorption effect.

[0015] (2) In the punching machine used for metal manufacturing, the corrugations of the rubber sheet contact the surface of the plate during movement, and the bending sheet is squeezed by the clamping plate, so that the rubber sheet and the surface of the plate are more closely attached under the influence of the reaction force of the bending sheet, which helps to improve the clamping effect. The bottom of the support plate contacts the top of the processing table during movement, and the processing table applies a supporting force to the support plate, so that the clamping plate contacts the processing table after firmly clamping the plate, thereby preventing the clamping plate from shaking during stamping and affecting the stamping accuracy.

[0016] (3) In the stamping machine used for metal manufacturing, the contact plate moves upward to drive the plate to move upward. After stamping is completed, the contact plate moves upward to eject the plate, which is convenient for operators to quickly retrieve the stamped plate, which helps to improve production efficiency. During the movement of the short block, it contacts the surface of the protrusion, and vibration is generated through intermittent contact between the short block and the protrusion, so that the contact plate vibrates together when ejecting the plate upward, avoiding the plate from getting stuck after stamping and ensuring the smooth demolding work.

[0017] (4) In the stamping machine used for metal manufacturing, the bottom of the pressing plate contacts the bottom of the inner wall of the receiving box during movement. The pressing plate squeezes the collected debris, which can reduce the space occupied by the debris, helping the receiving box to collect more debris at one time. The L-shaped rod is separated from the limit groove of the processing table during movement. The double limit prevents the operator from moving the receiving box in the wrong situation, causing the debris to fall into the working area during collection, increasing the difficulty of cleaning.

[0023] The clamping device includes a driving motor 41, a clamping plate 42, a bending piece 43, a sliding column 44, a rubber plate 45, a stop block 46 and a supporting plate 47. The output end of the driving motor 41 drives the clamping plates 42 to move toward each other, the movement of the clamping plates 42 drives the bending piece 43 to move toward the sliding column 44, and the movement of the bending piece 43 drives the sliding column 44 to move toward the rubber plate 45. The driving motor 41 is fixedly mounted on the top of the processing table 1, the clamping plate 42 is fixedly mounted on the output end of the driving motor 41, the bending piece 43 is fixedly mounted on the inner wall of the clamping plate 42, and the sliding groove of the sliding column 44 runs through the clamping plate 42.

[0024] The bending piece 43 is elastic, and a corrugation 1 is provided on a side of the rubber plate 45 away from the sliding column 44. The movement of the sliding column 44 drives the rubber plate 45 to move toward the plate. The corrugation 1 of the rubber plate 45 contacts the surface of the plate during the movement. A spring 1 is provided between the stop block 46 and the clamping plate 42. An arc surface 1 is provided on the top of the stop block 46.

By squeezing the elastic bending piece 43, the rubber plate 45 can fit more closely to the plate under the reaction force exerted by the bending piece 43.

[0025] When the present embodiment is working, the punching mechanism 2 is started, and the punching end of the punching mechanism 2 contacts the top of the plate during its downward movement, so that the punching end moves and drives the plate downward, and the plate moves downward and drives the lifting plate 32 to move downward, and the lifting plate 32 moves downward and drives the telescopic end of the buffer damper 31 to move downward, and the telescopic end moves and drives the hollow cylinder 33 to move downward, and the hollow cylinder 33 moves and drives the Z-shaped piece 34 to move downward, and the Z-shaped piece 34 moves and drives the annular plate 35 to move downward, and the bottom of the annular plate 35 contacts the top of the buffer damper 31 during its movement, and the hollow cylinder 33 continues to move downward to squeeze the Z-shaped piece 34, and the Z-shaped piece 34 is deformed after being squeezed, so that the Z-shaped piece 34 exerts a reaction force on the hollow cylinder 33 under the influence of the elastic force, and the buffer is slowed down by providing the elastic Z-shaped piece 34. The telescopic end of the damper 31 moves downward at a speed, and the hollow cylinder 33 moves downward while squeezing the air between the hollow cylinder 33 and the buffer damper 31.

The upward movement of the hollow cylinder 33 creates a negative pressure between the hollow cylinder 33 and the buffer damper 31, and the external air slowly enters between the hollow cylinder 33 and the buffer damper 31 through the air holes on the rotating plate 37, thereby reducing the rebound force after stamping by increasing the resistance encountered by the telescopic end of the buffer damper 31 when it resets.

[0026] The plate is manually placed between the clamping plates 42, and the driving motor 41 is started. The output end of the driving motor 41 drives the clamping plates 42 to move toward each other.

The movement of the bending piece 43 drives the sliding column 44 to move toward the rubber plate 45. The movement of the sliding column 44 drives the rubber plate 45 to move toward the plate. The corrugation of the rubber plate 45 contacts the surface of the plate during the movement, so that the rubber plate 45 clamps the plate. The clamping plates 42 continue to move and squeeze the bending piece 43, so that the bending piece 43 is deformed and then moves against the sliding column 44 applies a reaction force, and by providing an elastic bending piece 43, the rubber plate 45 can fit the plate more closely. During the surface deformation of the bending piece 43, it contacts the arc surface of the stop block 46, so that the deformation of the bending piece 43 drives the stop block 46 to move downward, and the movement of the stop block 46 drives the support plate 47 to move toward each other. During the movement of the bottom of the support plate 47, it contacts the top of the processing table 1, so that the processing table 1 applies a supporting force to the support plate 47. After the rubber plate 45 firmly clamps the plate, the stability of the clamping plate 42 is increased, and the influence of the clamping plate 42 during the buffer pressure is reduced.
