The first die 6 and the second die 7 are arranged opposite to each other, and the first die 6 can approach or move away from the second die 7 along the first straight line 100 to clamp or release the workpiece.

[0043] Reference Figure 5 , multiple cutters 8 are arranged at intervals along the second straight line 200, and multiple cutters 8 are inserted into multiple first punching holes 61 one by one. The cutters 8 can move along the first straight line 100 relative to the first mold 6 to penetrate into the second punching holes 71. The first straight line 100 is perpendicular to the second straight line 200. The first punching hole 61 and the second punching hole 71 are both on the displacement route of the cutter 8. In this embodiment, the cross section of the cutter 8, the cross section of the first punching hole 61, and the cross section of the second punching hole 71 are all T-shaped.

[0044] The working process in this embodiment is as follows: the first mold 6 is close to the second mold 7 so that the first mold 6 and the second mold 7 can clamp the workpiece, and then the tool 8 is close to the second mold 7 until the tool 8 enters the second punching hole 71, and the tool 8 punches the workpiece (the tab raw material 400). In this embodiment, the cross-section of the tool 8 is T-shaped, and two adjacent tools 8 can punch a T-shaped tab out of the strip-shaped tab sheet raw material.

The knife seat 3 and the first mold 6 are arranged at intervals, and the length of the guide rod 32 is greater than the sum of the upper and lower thicknesses of the first mold 6 and the knife seat 3. The second mold 7 is installed on the base 4.

[0046] In this embodiment, the knife seat 3 slides relative to the base 4, driving the first mold 6 to approach the second mold 7. After the first mold 6 and the second mold 7 contact, as the knife seat 3 continues to move downward, the spring is compressed, and the gap between the knife seat 3 and the first mold 6 is reduced until the knife seat 3 hits the first mold 6, so that the gap between the first mold 6 and the second mold 7 can firmly clamp the pole ear. Then, the tool 8 moves downward relative to the first mold 6, driving the lower end of the tool 8 to punch the pole ear and allowing the tool 8 to enter the second punching hole 71, thereby completing the effect of cutting the pole ear and producing multiple T-shaped pole ears.
