Die for forging production of aluminum alloy control arms

Abstract

The invention provides a mold for forging and producing an aluminum alloy control arm, and the mold is composed of an upper mold (4), a guide column (3) and a lower mold (2). The beneficial effect of the present invention is that, by designing the connection, guide and positioning structures of the mold design, the requirements of the automatic production of the control arm can be met, and the production of multiple pieces in one mold can be realized.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a mold for forging and producing an aluminum alloy control arm. Background technique [0002] The control arm is an important component in the car suspension system. Constrain the trajectory of the wheel, bear the lateral impact, connect with the shock absorber or spring, bear the impact from the driving of the vehicle, have sufficient strength, stiffness and service life; the current control arm materials are mainly steel or aluminum alloy 2 species; aluminum alloy due to its light weight, more and more widely used. [0003] At present, there are two production methods of aluminum alloy control arms: casting and forging; the forging process is mostly roll forging or die forging, using equipment such as hot die forging presses, friction presses or roll forging machines; the manufacturing process is generally: heating Bar material, partial upsetting and flattening, bending, p...

Problems solved by technology

[0003] At present, there are two production methods of aluminum alloy control arms: casting and forging; the forging process is mostly roll forging or die forging, using equipment such as hot die forging presses, friction presses or roll forging machines; the manufacturing process is generally: heating Bar material, partial upsetting and flattening, bending, pre-forging, final forging, edge trimming, shaping and other processes are formed; the production methods are mostly manual or semi-automatic and the production efficiency is low; and the production process requires upsetting and flattening, elongation , bending, pre-forging, final forging and other sets of molds and equipment cost a lot of investment.

[0004] Most of the control arm forging dies currently in use cannot meet the needs of automated production; during the production process, blank processing positioning, blank processing station transfer and positioning, and blank automatic demoulding are manually involved, so it is easy to cause blank positioning. Defects such as billet bias, folding, and dissatisfaction with filling; and it is impossible to realize one-mold multi-piece processing and automatic production; product quality is unstable and yield rate is low

In addition, the blank needs to be additionally designed to operate the holding end, and the excess metal at the holding end will be cut off at last, so the metal utilization rate is not high
