Description

Bending punching device

Technical Field

The utility model belongs to the technical field of automobile decorative strip processing, and relates to a bending and punching device.

Background

In bending die production of products, it is often necessary to punch holes into the trim product for subsequent positioning or to produce the feature itself in this process. The bending die is convenient for loading and unloading due to metal forming principle and production operators, and is usually used for taking and unloading operation in front of operators, so that space in front of the operators is required to be abdied for matching with the die forming and the convenient operation of the operators. There are two methods generally employed today: the rotary punching mechanism and the overturning punching mechanism have extremely high requirements on the manufacturing process of the rotary punching mechanism, the mechanism qualification rate is often caused by low part manufacturing precision, the problems of mechanism operation blocking, rotation shaft drawing, breakage and the like are solved, and the centers of a male die and a female die are often deviated, so that the service lives of the female die and the male die are reduced. The whole manufacturing cost of the mechanism is high; the overturning and punching mechanism has larger impact, shorter service life, easy cracking in the use process of parts and larger noise; with the impact force, the hole site of the product is easy to deviate, and bad products are caused.
