[0039] The bidirectional threaded rod 11 and the clamping plate 13 can be used to fix the sheet metal body 24, which facilitates subsequent stamping processing.

[0040] Reference Figure 4 and Figure 7 In a preferred embodiment, the position adjustment mechanism includes an adjustment groove formed on the upper surface of the mounting platform 1. A motor 15 is fixedly mounted on the right side surface of the mounting platform 1.

A sliding opening is provided on the inner top wall of the L-shaped mounting plate 3, extending into the interior of the sealing cylinder 19. An L-shaped transmission rod 20 extending into the interior of the sealing cylinder 19 is fixedly connected to the back of the connecting plate 5 through the sliding opening. A piston 25 is fixedly installed at one end of the L-shaped transmission rod 20 located inside the sealing cylinder 19.

[0045] By setting up the sealing cylinder 19 and the ventilation chamber 21, when the hydraulic press 4 drives the stamping head 6 to move up and down to perform stamping operations via the connecting plate 5, the air pressure in the sealing cylinder 19 is pushed into the ventilation chamber 21 and blown out through the air outlet, which can cool down the workpiece that has just been stamped.

[0046] Working principle: During use, the sheet metal body 24 to be stamped is placed on the pad 2. Rotating the operating lever drives the bidirectional threaded rod 11 to rotate. Under the guidance of the guide slider 14, the two threaded blocks 12 can move closer together through the rotation of the bidirectional threaded rod 11, until the two clamping plates 13 clamp and fix the sheet metal body 24, preventing the sheet metal body 24 from shaking or shifting during subsequent stamping. During stamping, the hydraulic press 4 descends through the stamping head 6 on the connecting plate 5 until the stamping operation is completed. During this period, the downward movement of the connecting plate 5 is transmitted through the transmission gear on the L-shaped rack 10. The rotation of gear 9 drives the rotation of guard rod 8. The rotation of guard rod 8 can push the hand of the person located below the stamping head 6 out, thereby achieving the effect of preventing pinching. When the stamping process is completed, the hydraulic press 4 runs and drives the stamping head 6 to move upward and reset through connecting plate 5. During this period, the upward movement of connecting plate 5 drives piston 25 to move upward synchronously in sealing cylinder 19 through L-shaped transmission rod 20. The air pressure in sealing cylinder 19 is pushed into ventilation chamber 21 through air outlet pipe 23 and blown out through several air outlet holes. This can cool down the workpiece that has just been stamped and prevent the person from being burned when collecting the workpiece.
