Description

Technical Field

[0001] The utility model belongs to the technical field of punching machines for leather processing, and particularly relates to a punching machine with adjustable inner diameter size. Background Technique

[0002] The punching machine used in leather processing is a machine specifically used to punch various required holes in materials such as leather. The working principle of the leather punching machine is that the punching head is driven to act up and down through a power transmission system, and the cutting tool quickly enters and exits the material to generate holes therein. It uses the mechanical stamping method, and through the rotation radius of the crankshaft, it achieves mechanical reciprocating cyclic motion to form the stamping function. The operation method of the leather punching machine includes the following steps: Fix the leather material on the workbench. Select a suitable punching tool and install it on the punching head. Turn on the power of the punching machine, and after the head runs up and down normally, enter the next step. Adjust the height of the punch and the stroke of the stroke control system so that the cutting tool just passes through the thickness of the material. Manually push the material into the punching head, and keep a safe distance between the fingers and the tool during operation. After punching, remove the material on the workbench and turn off the power of the punching machine.

[0003] However, the punching machine still has the following defects: According to the process requirements, the punching machines on the market use a five-group head method to punch leather. Among them, five groups or more groups of punches can be equipped with punching tools according to different process requirements, and have the effect of automatically adjusting the inner diameter size. However, in addition to this, when punching leather, it is usually fixed by using adhesive tape or other adhesion methods and then punching. This method not only poses a safety hazard to the punching machine, but also causes the phenomenon of leather shedding and incomplete punching, affecting the processing efficiency.
