[0033] Working principle:
[0034] Step 1: When using, first place the stamping material to be stamped in the inner cavity of the U-shaped clamp 23, open the second cylinder 24, and the clamping plate 25 will move downward through the second cylinder 24 to fix the stamping material. After fixing, open the first cylinder 22, and the U-shaped clamp 23 and the stamping material will move to the left through the first cylinder 22. At the same time, under the action of the first spring 33, the positioning plate 32 will move downward to fix the stamping material. Then, under the action of the fourth cylinder 52, the top die 53 will move downward and cooperate with the bottom die 54 to stamp the stamping material.
[0035] Step 2: After the first cylinder 22 moves the U-shaped clamp 23 to the designated position, the second cylinder 24 moves the clamping plate 25 upward, releasing the limit on the stamping material. Then, the first cylinder 22 moves the U-shaped clamp 23 back to its original position, continuously moving the stamping material. When it is being inspected, the fourth cylinder 52 moves the top mold 53 upward, causing the inclined block 47 to move the second spring 491 outward, so that the top mold 53 moves upward to the designated position. Finally, the inclined block 47 limits the bottom of the top mold 53. When the limit is released, the third cylinder 43 is opened, and the third cylinder 43 moves the mounting plate 42 and the L-shaped seat 41 to both sides, thereby releasing the limit. This method has the advantages of convenient movement and high safety.
