[0002] Stamping is a forming processing method that applies external forces to plates, strips, tubes, profiles, etc. by a press and a die, causing them to undergo plastic deformation or separation, so as to obtain workpieces (stamped parts) with the required shapes and sizes. Stamping and forging belong to plastic processing (or pressure processing) together, collectively called forging and pressing. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and steel strips.

Through the setting of the moving component 3, the position of the sliding seat 2 can be adjusted. And the setting of the buffer component 9 can play a buffering role to avoid damage to the pressing plate 7 due to its fast stamping speed.

[0025] On both sides at the front side of the aggregate trough 20, L-shaped plates 201 are respectively provided. And the inner sides of the L-shaped plates 201 are respectively fixedly installed on the processing table 10. Bolts 202 are respectively movably penetrated and installed on the front sides of the L-shaped plates 201.

Pressing rollers 96 are respectively fixedly installed at the upper part of the inner cavity of the U-shaped plate 95, which can play a buffering role when the pressing plate 7 presses downward.

[0030] Sliding blocks 951 are respectively fixedly installed at the bottoms of the U-shaped plates 95, and the sliding blocks 951 are respectively located in the inner cavities of the adjacent grooves. Sliding rods 952 are respectively slidably penetrated and installed on the sliding blocks 951.

Return springs 953 are respectively sleeved on the output shafts of the sliding rods 952, and the two ends of the return springs 953 are respectively fixedly installed on the inner wall of the groove and the sliding block 951, playing a buffering role.

[0031] In this embodiment: When the pressing plate 7 moves downward, it drives the n-shaped rod 92 to move downward through the flat plate 91. When the n-shaped rod 92 moves downward, it drives the trapezoidal block 93 to move downward. When the trapezoidal block 93 moves downward, it slowly inserts between the adjacent pressing rollers 96 on one side and squeezes them, so that the pressing rollers 96 move in the opposite direction and stretch the return spring 953, which can play a buffering role.

[0032] Working principle: During use, the operation of the servo motor 34 drives the rotation of the threaded rod 32 on one side. Then, through the transmission of the belt 321, the threaded rods 32 on both sides are driven to rotate. When the threaded rod 32 rotates, it drives the movement of the threaded sleeve 31. When the threaded sleeve 31 moves, it jointly drives the sliding seat 2 to move forward. When the sliding seat 2 moves forward, it drives the processing table 10 to move forward. After moving forward to a suitable position, the worker can place the workpiece on the processing table 10. Then, through the operation of the hydraulic cylinder B40, the clamping plates 50 on both sides are driven to move relatively, so as to realize the clamping and fixing of the workpiece. After the clamping and fixing are completed, reverse operation can make the sliding seat 2 and the processing table 10 return to their original positions. At this time, through the operation of the hydraulic cylinder A6, the pressing plate 7 is driven to move downward. When the pressing plate 7 moves downward, it drives the punch 8 to move downward to cooperate with the through hole to realize the stamping of the workpiece, and the debris will fall into the inner cavity of the aggregate chute 20. When the pressing plate 7 moves downward, it drives the n-shaped rod 92 to move downward through the flat plate 91. When the n-shaped rod 92 moves downward, it drives the trapezoidal block 93 to move downward. When the trapezoidal block 93 moves downward, it slowly inserts between the adjacent extrusion rollers 96 on one side and extrudes them, so that the extrusion rollers 96 move in the opposite direction and stretch the return spring 953, which can play a buffering role.
