Bending equipment for compensating for thickness of automobile part profile and process using method of bending equipment

Abstract

The invention discloses bending equipment for compensating for the thickness of an automobile part profile. The bending equipment comprises an upper-layer operating table, a middle-layer operating table, a lower-layer operating table, a first propelling device, a second propelling device, a first pressure device and a second pressure device, wherein the upper-layer operating table, the middle-layer operating table and the lower-layer operating table are distributed in parallel in the longitudinal direction, the first propelling device and the second propelling device are oppositely distributedon the two sides of the middle-layer operating table, and the first pressure device and the second pressure device are arranged at the bottom of the upper-layer operating table and the top of the lower-layer operating table correspondingly. A first pressing and holding portion and a second pressing and holding portion can be partially attached to a strip-shaped profile, and the first pressing andholding portion and the second pressing and holding portion can provide pressure from the side, close to the second propelling device, of the strip-shaped profile to the side, close to the first propelling device, of the strip-shaped profile. By means of the bending equipment, rigidity damage to the strip-shaped profile in the bending process is effectively reduced, and the quality of the strip-shaped profile to be bent is guaranteed.

Description

technical field [0001] The invention relates to the field of processing auto parts or the field of bending strip profiles, in particular to a bending device and a process using method for compensating the thickness of profiles of auto parts. Background technique [0002] At present, the curved strip profiles are used by all walks of life, especially in the field of machinery and auto parts processing. Auto parts processing is the unit that constitutes the overall processing of auto parts and the products that serve the processing of auto parts. There are many types of auto parts. With the With the improvement of people's living standards, people consume more and more cars, and the market for auto parts is getting bigger and bigger. In recent years, auto parts manufacturers are also developing rapidly. During processing, usually a thin plate with a small thickness is processed first, and then the thin plate is cut into a plate body according to the required size, and then th...

Problems solved by technology

The punch of the traditional bending machine moves in a straight line, that is, the movement track of the punch is perpendicular to the plane of the plate. When the punch bends and deforms the plate, the punch also needs to slide relative to the concave surface of the plate for extrusion. Or exit, one side of the extruded board will lose thickness because it is extended into an outer arc profile, and the other side will bulge due to shrinkage into an inner arc profile, making the thickness increase, and the overall thickness becomes And uneven, the amount of work that needs post-processing also becomes large and the processing is complicated

In order to make the shell more beautiful, it usually requires multi-step polishing on the surface of the board after bending. However, at the beginning of polishing, on the one hand, it is easy to further reduce the thickness of the board and reduce the strength of the board; on the other hand On the one hand, it will increase the processing procedures and reduce the processing efficiency
