Forging die of steering knuckle and forming process of forging die

Abstract

The invention relates to a forging die of a steering knuckle and a forming process of the forging die. The forging die of the steering knuckle comprises an upper die body and a lower die body, and the upper die body and the lower die body are simultaneously and correspondingly arranged in a blank making step, a flattening step and a finish forging step. A blank making cavity is formed in the lower portion of the left side of the lower die body, a flattening cavity is formed in the upper portion of the left side of the lower die body, a finish forging cavity is formed in the middle position of the lower die body, and the upper die body is correspondingly provided with a blank making cavity, a flattening cavity and a finish forging cavity corresponding to the lower die body. The blank making cavity formed in the upper die body is a deep cavity. The forming process of the forging die of the steering knuckle comprises the following steps of heating, blank making, flattening and finish forging. According to the forging die of the steering knuckle and the forming process of the forging die, the original three-station arrangement form is adopted, the surface quality of a forge piece is improved, the material utilization rate is increased, the rejection rate is reduced, the production efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to a forging die of a steering knuckle and a forming process thereof. Background technique [0002] At present, during the production of a steering knuckle forging, the blank needs to be heated twice to form the forging. This process has the following disadvantages: serious oxidation pits on the surface of the forging, difficult forming, low material utilization, safety risks in operation, and very high cost. High disadvantage. [0003] For this knuckle, see figure 1 , the forging process is: heating (first time) → billet (free forging) → heating (second time) → flattening (die forging) → final forging (die forging). During the forging production process of this product, the billet making, flattening, and final forging are not on the same piece of equipment, and the time required for the billet to be hit by the air hammer for many times is relatively long, resulting in the failure of the next process after the temperature of the...
