Description

BLANKING APPARATUS

The present invention relates to a percussion device, and more particularly, to a percussion device for performing percussion on a base material.

In general, a flexible printed circuit board (FPCB) on which an electronic circuit is printed on one side is applied to a portable terminal or an electronic product. The flexible circuit board is formed of a film material having a thickness of about 0.1 mm, which is excellent in flexibility and flexibility.

Such a flexible circuit board is manufactured in various sizes and shapes through a punching process using press equipment having upper and lower dies. That is, conventionally, a base material is placed on a lower mold, and then an upper mold having a perforated blade is lowered to puncture the base material to form a flexible circuit board having a predetermined shape on the base material.

However, in the past, the worker has to supply the pre-cut base material to the press equipment, and since the scrap formed at the portion where the punching has been performed by using the compressor or the like is completed after the punching is completed, The productivity is lowered, the manufacturing cost is increased, and scrap and fine dust generated at the time of perforation are introduced into the bronchi of the worker.

In addition, conventionally, when the base metal is disposed on the lower mold and the upper mold is moved downward at a high speed to perform the punching in such a manner that the punch blades penetrate the base metal, an impact is transmitted to the base metal at the time of punching, There is a problem that bending or twisting phenomenon occurs in the base material and the puncture can not be performed at the correct position.

In addition, conventionally, scrap is removed by manual operation, so that it is difficult to completely remove the scrap. As a result, the scrap is adhered to the base material and the subsequent process proceeds to cause defects in the product. There is a problem that the whole process is delayed.
