[0002] Metals can be divided into non-ferrous metals and ferrous metals by their colors, such as steel, iron alloys and cast iron. Ferrous metals have good electrical and thermal conductivity. When producing and processing ferrous metal workpieces, stamping devices are required.

[0003] For example, an automatic stamping processing device for non-ferrous metal smelting with publication number CN216655967U includes an operating table, a buffer groove is provided at the upper end of the operating table, grooves are symmetrically provided on the front and rear sides of the inner cavity of the buffer groove, and reset grooves are symmetrically provided on the left and right sides of the inner cavity of the buffer groove. A support plate is welded at the upper end of the operating table, a stamping mechanism is installed at the upper end of the support plate, a bearing plate is provided in the buffer groove, a stamping die table is connected to the upper end of the bearing plate by bolts, sliders are symmetrically welded on the front and rear sides of the stamping die table, and a buffer mechanism is provided at the lower end of the bearing plate. When the stamping device stamps the non-ferrous metal, the stamping device drives the The nonferrous metal material and the stamping die table move downward, and the stamping die table drives the bearing plate to move downward. The buffer mechanism and the reset mechanism cooperate to achieve soft stamping of the nonferrous metal, and reduce the vibration of the nonferrous metal during the stamping process. However, during stamping, the contact position between the upper platen and the output end of the press is subjected to greater force, that is, the center position of the upper platen is subjected to greater force, while the surrounding positions are subjected to less force, which easily leads to uneven extrusion pressure of the upper platen. When the stamping speed is too fast, the depth of the stamped ferrous metal is uneven, some are deep and some are shallow, thereby affecting the stamping efficiency and qualified rate of the product and reducing the stamping effect of ferrous metal.

The pressurizing cylinder 41 continues to drive the connecting plate 42 downward, and the connecting plate 42 drives the sliding sleeve 45 downward, and the block 47 slides in the inclined groove 46, causing the sliding sleeve 45 to spirally descend.

[0042] The sliding sleeve 45 then drives the pressure rods 49 and pressure blocks 411 on both sides to descend, so that the pressure rods 49 rotate and open, and the spring 1 410 is stretched, so that the pressure block 411 is close to the pressure plate part 43. The pressure rod 49 is stretched and drives the auxiliary rod 413 at the bottom to be stretched, and the spring 2 414 is stretched, and the auxiliary rod 413 increases the contact area with the pressure plate part 43, thereby introducing the force of the connecting plate 42 to the surrounding positions of the pressure plate part 43, reducing the uneven force.

[0043] When the pressurizing cylinder 41 starts to press down, the pressurizing cylinder 41 will also drive the fixing sleeve 51 and the connecting rod 52 to press down, the connecting rod 52 will drive the vertical rack 53 to press down, the vertical rack 53 will drive the gear 56 to rotate, the gear 56 will drive the screw rod 55 to rotate, due to the limitation of the limiting rod 58, the threaded sleeve 57 will move toward the middle, the threaded sleeve 57 will drive the fixing plate 59 to move, the fixing plate 59 will drive the sliding rod 510 and the clamping plate 511 to move, so that the clamping plates 511 on both sides will press the two sides of the metal tightly.

[0044] Then the threaded sleeve 57 continues to move to drive the fixed plate 59 to compress the spring four 512. The fixed plate 59 moves to drive the mounting bar 513 and the transverse rack 514 to move. The transverse rack 514 moves to drive the fan-shaped tooth block 516 to rotate. The fan-shaped tooth block 516 drives the clamping rod 517 to shrink toward the middle, so that the clamping rods 517 on both sides press the positioning plate 66 and the back plate 62 tightly, thereby improving the positioning effect of the metal.

[0045] After the stamping is completed, the pressurizing cylinder 41 is started to rise, the connecting plate 42 drives the pressing plate part 43 to rise, the threaded sleeves 57 on both sides move outward, the clamping plate 511 releases the clamping of the metal on both sides, and then the threaded rod 64 is reversed, so that the movable sleeve 65 drives the positioning plate 66 to move, and the front and rear clamping of the metal is released, and the stamped metal parts can be removed.
