When an automotive part needs to be raised before stamping, the electric telescopic rod 17 is first extended. At this time, the electric telescopic rod 17 drives the scissor lift 14 to extend, thereby raising the base 1 with the help of the lifting column 5. After the adjustment is completed, the electric telescopic rod 17 is closed, the raw material is placed inside the mold 6, and then the machine body 7 is turned on, causing the stamping rod 8 to move the stamping plate 9 downward. At this time, the second slide rod 23, with the help of the arc-shaped fifth slide groove 21, drives the protective rod 22 to rotate on the first slide rod 19, thereby preventing the operator's palm from being crushed. At the same time, the slide plate 24 moves downward. The movement is driven by the linkage 25, which rotates the four-bar linkage mechanism, causing the guide plate 29 to move to the right to avoid interference between the guide plate 29 and the stamping plate 9. After stamping is completed, the stamping rod 8 moves upward, the protective rod 22 resets, and the guide plate 29 moves to the left under the action of the four-bar linkage mechanism. At the same time, the stamped parts on the stamping plate 9 fall onto the guide plate 29. Due to the inclined setting of the guide plate 29, the stamped parts will fall onto the holding plate 38 of the material cart 30. As more and more stamped parts accumulate on the holding plate 38, the holding plate 38 will slide downward. When it slides to the point where the pressure block 39 contacts the tactile switch 37, the alarm 31 will sound. At this time, the staff can collect the stamped parts in the material cart 30.
