Example Embodiment

[0054] Example one:

[0055] A method for forming a beam of an automobile rear axle bracket assembly, the method includes the following steps (see figure 1 Flow chart shown):

[0056] A. Blanking: The blanking die 1 is used to punch the steel plate on the punching machine to obtain a waist-drum-shaped blank plate 2 with multiple mounting holes in the middle and large at both ends;

[0057] B. Forming: Using a forming die 3 on a hydraulic press, the waist drum-shaped blank plate 2 is stamped into a preformed tank 4 composed of a deformed top surface and two waist-drum-shaped sides;

[0058] C. Shaping: 4 pairs of pre-formed tanks continue to be shaped on the hydraulic press;

[0059] D. Punching side holes: The punching die 5 is used on the punching machine to punch the side holes of the reshaped preformed trough body 4 to obtain the finished automobile rear axle bracket assembly beam 6.

[0060] The blanking mold 1 used in the above step A includes a blanking upper mold base 101, a blank...

Abstract

The invention discloses a method for forming a car rear shaft support assembly cross beam and relates to a production method of car parts. The method comprises steps of blanking: conducting stamping for a steel plate by using a blanking die on a punch, and obtaining a waist-drum-shaped blank plate; forming: stamping the waist-drum-shaped blank plate to form a preforming type groove body formed by a deforming top surface and two waist-drum-shaped sides by using a forming die on a hydraulic press; shaping: continuing to shape the preforming type groove body on the hydraulic press; and punching side holes: conducting side hole punching for the shaped preforming type groove body on the hydraulic press by using a punch die, and obtaining a car rear shaft support assembly cross beam product. The production cost is low, the production efficiency is high, the product quality is stable, and requirements for batch production and large-scale production are met.

Description

technical field [0001] The invention relates to a method for manufacturing auto parts, in particular to a method for forming a beam of an automobile rear axle support assembly. Background technique [0002] The beam of the automobile rear axle bracket assembly is a channel steel composed of a deformed top surface and two drum-shaped sides. Its structure is relatively complicated and it is difficult to manufacture. The existing manufacturing method of the beam of the rear axle support assembly of an automobile generally includes the following steps: shearing, drawing, punching mounting holes, trimming, flanging, and punching side holes. Therefore, it is necessary to reserve enough side material for the deep drawing operation. After the deep drawing, the edge needs to be trimmed and flanged to remove the excess side material. Therefore, this method not only wastes more steel plate materials, but also produces The cost is high, and the process is relatively complicated, and th...
