Springback prevention bending mold for machining automobile spare parts

Abstract

The invention discloses a springback prevention bending mold for machining automobile spare parts. The springback prevention bending mold comprises a male mold machining part and a female mold machining part which is placed at the upper end of the male mold machining part and matched with the male mold machining part. The springback prevention bending mold for machining automobile spare parts is characterized in that the male mold machining part comprises a lower fixing plate and a male mold fixed at the upper end of the lower fixing plate, buffer bearing parts are arranged on the two sides of the male mold, the buffer bearing parts comprise telescopic supporting pillars and bearing tables fixed at the upper ends of the supporting pillars, the bearing tables are provided with positioning grooves, and the initial position of each bearing table and a platform at the top end of the male mold are placed in the same horizontal line; the female mold machining part comprises an upper fixing plate and a female mold fixed at the lower end of the upper fixing plate, and a positioning table of the female mold is provided with positioning protrusions used for being matched with the positioning grooves; the female mold machining part is communicated with a press machine through a pressure transmission shaft. The springback prevention bending mold has the advantages of being simple in structure, high in practicability, good in springback prevention effect and the like.

Description

technical field [0001] The invention relates to the field of auto parts processing, in particular to an anti-rebound bending mold for auto parts processing. Background technique [0002] At present, the bent plate used for auto parts has a rectangle or other raised grooves on the rectangle. In the prior art, when processing this kind of bent plate, ordinary bending machines are often used for bending, and it takes two times to form the shape, so the processing speed is slow, the production efficiency is low, and the size of the bent plate is not easy to control , resulting in lower precision of the bent plate and easy springback. [0003] Therefore, it is necessary to provide a bending die to solve the deficiencies in the prior art. Contents of the invention [0004] According to the technical problem raised above, an anti-rebound bending mold for processing auto parts is provided. The present invention mainly utilizes the addition of buffer receiving plates on both sid...
