During the production process of the melt 10, the material strip 11 is first punched by the punching device 140, and then cut into sheets by the cutting device 130. In this embodiment, compared with the method of cutting the material strip 11 first and then punching, even if a half hole is formed on the edge of the cut sheet, the half hole on the edge of the sheet has good molding accuracy and quality.

Then, the first cutting fixed block 133 squeezes the material strip 11 on the second cutting movable block 136. Under the action of the second cutting elastic member, the second cutting movable block 136 is misaligned with the second cutting fixed block 135 and cuts the material strip 11 to form a sheet, which is stable and reliable.

Among them, the feeding stroke refers to the distance that the material strip 11 is transferred each time the punching device 140 punches a hole. It can be understood that a row of first punching needles 1411 punches holes in the material strip 11 once, and the punching holes formed are a row of holes in the melt 10 along the length direction.

Compared with a one-time punching forming, the punching forming accuracy is more effectively guaranteed, and the deformation of the material strip 11 caused by punching is effectively reduced.

[0088] It is understandable that the cross-sectional shape of the second punching needle 1412 and the third punching needle 1413 may be the same as the half-hole shape of the punching hole.

The second punch needle 1412 is inserted into the second guide channel. Under the push of the punching drive member 144 and the guidance of the second guide channel, the second punch needle 1412 punches the material strip 11 in the punching channel 14311, and the cut waste material is pushed into the second blanking channel by the second punch needle 1412.

[0096] Exemplarily, the guide channel 14312 includes a plurality of third guide channels corresponding one-to-one to the third punch needles 1413, and the blanking channel 14313 includes a plurality of third blanking channels corresponding one-to-one to the third punch needles 1413.

[0098] Specifically, the first feeding device 150 includes a first fixed clamping assembly 151, a first movable clamping assembly 152 and a first translation drive assembly 153.
