Example Embodiment

[0021] With reference to the drawings, a method for forming beam parts includes the following steps:

[0022] (1) Stretch forming: open the side of the beam part to both sides to form an angle with the vertical surface, and stretch it at this angle;

[0023] (2) Shaping: according to the surface requirements of the product, the surface of the beam parts is shaped through the side shaping process (or general shaping process).

[0024] As a preferred implementation of this example, the step (1) specifically includes the following steps:

[0025] (1-1) The mold is opened on the machine tool, and the lower mold pressing ring is 10-20mm higher than the upper surface of the punch;

[0026] (1-2) Put the material in the positioning area;

[0027] (1-3) The slide of the machine tool moves down, and the upper mold closes the material on the lower mold pressing ring;

[0028] (1-4) The slider continues to descend, and the blank begins to be drawn into shape under the action of the blank holder and ...

Abstract

The invention discloses a forming method of a beam part. The forming method comprises the steps that the side face of the beam part is opened towards the two sides so that an included angle can be formed between the side face of the beam part and the vertical face, the beam part is drawn and formed at the included angle, and then the surface of the beam part is shaped and formed according to the surface requirement of a product through a side shaping process. According to the forming method of the beam part, one-time forming of the beam part is changed into two-time forming, the manufacturingdifficulty of the beam part is lowered, the part which cannot be formed originally is changed to be possibly formed, the difficulty of the two-time forming technology is greatly reduced, the cracking,damage and bending rebound risk of the surface of the part are greatly reduced, the forming is stable and reliable, the rebound is small, and the precision is high.

Description

technical field [0001] The invention relates to the technical field of part forming, in particular to a forming method of beam parts. Background technique [0002] The existing forming methods for beam parts in automobiles and related fields are mainly produced by direct drawing after process supplementation. The main disadvantage of the original process is that the two sides of the beam have large springback and uneven surface, commonly known as "flower pot-shaped back". The surface is prone to cracking and the rate of scrap is high, the surface accuracy of the parts is poor, the parts are distorted, and the matching degree with the matching parts is poor, which makes it difficult to meet the welding requirements of the assembly assembly. Contents of the invention [0003] In order to solve the above technical problems, the technical solution provided by the present invention is: a forming method of beam parts, comprising the following steps: [0004] (1) Drawing forming...
