Auto body-in-white blanking device

Abstract

The invention provides a blanking device for a body in white of an automobile. The blanking device is applied to the technical field of the automobile body in white online welding equipment. A blanking tool (3) is arranged on a driving air cylinder (2) above a device pedestal (1) of the blanking device for the body in white of the automobile, a blanking female die (4) is arranged at the position, below the blanking tool (3), of the device pedestal (1), the device pedestal (1) is arranged on a sliding part (5), the sliding part (5) is arranged on a device base (6), and the driving air cylinder (2) is arranged to be of a structure capable of driving the blanking tool (3) to rise and fall. The blanking device for the body in white of the automobile is simple in structure, the body in white of the automobile can be conveniently and rapidly subjected to positioning hole punching, positioning boss pressing and other blanking work, the position precision of the blanking work such as secondarily-formed positioning holes and positioning bosses of the body in white of the automobile is improved, the occupied space is small, the blanking efficiency is high, the mold investment is reduced, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of on-line welding equipment for automobile body-in-white, and more specifically relates to a blanking device for automobile body-in-white. Background technique [0002] Punching is a stamping process that uses a die to separate part of the material or process part from another part of the material, process (process) part or waste. Blanking is a general term for separation processes such as shearing, blanking, punching, punching, notching, sectioning, chiseling, edge trimming, tongue cutting, cutting, and trimming. As the development cycle of automobiles becomes shorter and shorter, imperfect product design leads to constant design changes in the tooling development stage, and product quality goals are set higher and higher, the assembly requirements caused by accumulated errors are increasing. In the vertical process of automobile production, it is often necessary to carry out punching operations such as s...

AI Technical Summary

Problems solved by technology

During the automobile production process, it is often necessary to carry out punching operations such as secondary positioning holes and positioning bosses on the automobile body-in-white (referring to the automobile body-in-white sheet metal parts in the present invention). Partial modeling modification of automobile body-in-white sheet metal parts, or when the precision is not up to standard, mold redesign, partial adjustment and training will lead to problems such as excessive investment, long cycle, and invalidation of stable debugging, which will affect production and cannot meet the requirements. actual production needs
