Autocar spindle fork vertical type forging technique method

Abstract

The invention provides a vertical type forging technology method for an automobile steering yoke. The automobile steering yoke consists of a rod part, a ring flange, and fork ears symmetrically arranged on the ring flange form a whole. The vertical type forging technology method is characterized by comprising: a. a step of vertically parting die from the ring flange of the automobile steering yoke and the yoke ears at the two sides, making the die parting surface of the vertical die parting perpendicular to the rod part, and supplementing materials into the inner part of the yoke ears of the automobile steering yoke to form a draft angle; and b. a step of performing vertical forging and forming on a forging machine, and directly forging and forming the bottom of the inner part of the fork ears. Because the die parting form is changed, the material feeding is performed on the processing position of a part, the preforming process is optimized, and the vertical forging is realized; and the die parting area is reduced, the casting fins are reduced, the utilization rate of the materials is increased by more than 20 percent, the secondary preforming step in the horizontal forging process is avoided, the forging efficiency is improved, and the production cost is lowered. The bottom of the inner part of the yoke ears is directly formed by forging so as to remove the admittance at the bottom of the inner part.

Description

Technical field [0001] The invention relates to a steering knuckle part of an automobile steering system. Background technique [0002] In the automobile steering system, the structure of the steering yoke is formed as a whole by the rod, flange, and symmetrical fork lugs on the flange. The steering yoke is formed by forging, and the parts are manufactured in the blank using the horizontal forging process. , Parting along the axial direction (horizontal direction) of the steering fork, so that due to the draft angle and flash problems that must exist in forging, the bottom margin of the inner gear is large, and the flash is large, which needs to be passed during forging. Only two blanking processes can effectively ensure the forming of the part, so the utilization rate of the formed material is low, and the product cost is high. Summary of the invention [0003] The purpose of the present invention is to provide a forging process method for the steering knuckle fork of an automo...
