Automobile half-axle pendulum rolling formation technology mould

Abstract

The invention discloses an automobile half-axle pendulum rolling formation technology mould which is characterized by comprising a half-axle blank (1), a fixture body (2), a mold core (3), a lower mould (4) and an upper mould (5), wherein the mold core (3) and the upper mould (5) are arranged in the fixture body (2); when the upper mould (5) is installed, a 10-degree incline angle is formed by the center line of the upper mould (5) and the center line of the lower mould (4); the lower part of the half-axle blank (1) is fixed and does not jump; the half-axle blank (1) is rotated, and press formation is gradually realized. The automobile half-axle pendulum rolling formation technology mould has the beneficial effects of obviously improving the half-axle quality, being stable in geometric dimension and smooth in surface, saving the material, lowering the cost, being convenient in technological operation, safe and reliable, and improving the yield of forge pieces.

Description

technical field [0001] The invention relates to a process mold, in particular to a process mold for forming an automobile half shaft by swing rolling. Background technique [0002] The car half shaft is mainly subjected to bending and impact loads. It is one of the vulnerable parts of the car and one of the parts with the highest failure rate among the important structural parts of the car. It is a direct drive for wheel rotation and an important part for torque transmission. When the car is running, the torque output by the engine is transmitted to the half shaft through the multi-stage transmission and the active device, and then transmitted to the wheels by the half shaft to push the car forward or reverse. When starting or going uphill, the torque is very large, especially in emergency braking or driving on uneven roads, the working conditions are quite harsh. Therefore, it is required that the half shaft must have the ability to withstand impact, alternating bending fa...

Problems solved by technology

In the past, half-shaft forgings were all forged by air-membrane hammers. The technology was backward, the precision of the forgings was low, the surface quality of the half-shaft was poor, the scrap rate was high, the labor intensity was high, the mold was easily damaged, the production efficiency was low, and the waste of materials was high. High cost, not suitable for mass production, nor suitable for current market demand
