Description

[0001] APPARATUS OF CUTTING PRESS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a press cutting apparatus, and more particularly, to a press cutting apparatus that performs a cutting operation in which a cutter is rotated in an eccentric manner to enter a side portion of a cut material at an oblique angle in an oblique direction.

Generally, a press-cutting metal mold is a material which is cut into a desired shape by applying a pressure to an object to be cut.

The press cutting mold is used for cutting plastic plate, plastic film laminated with plural layers, FPCB (Flexible Printed Circuit Board), sticker, label, and recently, diffusion film, reflection film, prism, Prism protection film, and the like.

In a conventional press cutting method for cutting such products, a cut material is placed on a lower die, and then the cutter located on the lower die moves down vertically by the operation of the press and cuts the cut material placed on the lower die .

However, if the cutter is vertically lowered, for example, assuming that the cutter has a rectangular cross-sectional shape, the initial contact area between the cutter and the cutter becomes wider and the cutter presses the cutter partially There is a problem that the cut surface of the cut material is not smooth and is cut off rugely and the defect rate is frequently generated.
