A molding die for round tube type automobile anti-collision bar

Abstract

A molding die for a circular tube type automobile anti-collision bar, including a molding device, a pressing mechanism and a mandrel. , right pressing block, lower template, slider seat, upper template is pressed down with the punching machine, left and right wedge-shaped pressing blocks respectively match and touch left and right wedge-shaped sliders, left and right wedge-shaped sliders respectively push left and right pressing The block is closed, and the grooves of the left and right pressing blocks are closed to form an oblate hole that matches the outline of the oblate section of the processed anti-collision bar product; Components; the rear part of the mandrel is fixed, the front part extends between the grooves of the left and right pressing blocks, and the cross section of the front part of the mandrel gradually changes from circular to oblate. The present invention satisfies the processing requirements of product pieces at one time of molding, ensures product quality while significantly improving production efficiency, reduces labor intensity and production cost, and satisfies the requirements of batch production.

Description

Technical field [0001] The invention relates to a profiling device, in particular to a profiling die for a round tube automobile anti-collision bar. Background technique [0002] Among auto parts, round tube parts are quite common, and the anti-collision bar is an indispensable common round tube part. After the round anti-collision bar is formed by roll welding, some irregular shapes on the product need to be stamped again. Figure 7 , Picture 8 , Picture 9 The anti-collision bar product 12 shown, the cross-sectional shape of the anti-collision bar product changes from round to oblate, and the geometric dimensions of each part have relatively strict tolerance requirements, which cannot be completed by the rolling process, and it needs to be completed by a stamping die . In the prior art, the upper and lower molds are combined and pressed, the lower mold is fixed, and the upper mold is pressed down. The forming method of the oblate stamping parts of the product part is the oblat...

Problems solved by technology

The problem with this processing method is that two times of core piercing, core pulling and two presses are required to ensure that the product meets the requirements. Although this process method can process qualified products, the secondary stamping and secondary core piercing 1. The core pulling operation makes the production efficiency extremely low, consumes a lot of manpower and material resources, it is difficult to meet the requirements of large batch production capacity, and increases the production cost. It is a very uneconomical molding process method
