Description

Bending apparatus

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bending apparatus, and more particularly, to a bending apparatus having a simple structure and operation principle and easy maintenance.

As is well known, the banding device is mainly formed by bending a metal material or a non-ferrous metal material to be bent in a predetermined shape, and a hydraulic cylinder method using oil pressure is most widely used.

The hydraulic cylinder is advantageous in that a large amount of force is instantaneously exerted. However, the structure is complex and the hydraulic oil has to be used for a predetermined period of time, and it has been necessary to check whether the hydraulic oil is leaking. There was a problem that was not easy.

In addition, in a general bending apparatus, only the bending process in which the material to be bended is simply bent into a predetermined shape has been performed, and the bending process and the surface heat treatment process have not been simultaneously performed. Corrosion or the strength thereof is remarkably deteriorated.
