At this time, the second pressing block 3-2 installed on the second pressing cylinder 3-1 presses the material strip 1-2. When the mold part 1 is punched to the upper mold and just presses the material strip 1-2, the relaxing cylinder 4-1 is actuated, but the air source is not connected to the front air inlet of the relaxing cylinder 4-1, so the pulling part will not move horizontally with the action of the relaxing cylinder 4-1. The upper mold continues to move downward, and the material strip 1-2 pulls the pulling part to move on the relaxing guide rod 4-8, so that the material strip 1-2 can be relaxed. When the punching is completed and the upper mold completely leaves the material strip 1-2, the relaxing cylinder 4-1 returns to straighten the material strip 1-2, and the pulling cylinder 3-7 acts to complete the pulling. At this time, the first pressing cylinder 2-1 acts to press the material strip 1-2 to prevent the subsequent pulling cylinder 3-7 from moving with the material strip 1-2 when returning, making the pulling position inaccurate. At the same time, after the induction sheet 5-5 senses that the material is in place, the cutting cylinder 5-1 moves and returns to its original position after the cutting is completed. Then, the second pressing cylinder 3-1 moves to release the material belt 1-2. Then, the pulling cylinder 3-7 returns to wait for the next pulling. After the second pressing cylinder 3-1 returns to press the material belt 1-2, the first pressing cylinder 2-1 returns to release the material belt 1-2. At this point, one stroke action is completed, and the material belt is released, the material is pulled, the material tail is detected, and the cutting is completed.
