Problems solved by technology

However, the parts manufactured by the above molding process in the prior art have the following disadvantages: 1. The material utilization rate is low, most of which are about 60%, and some are even lower; 2. The stamping tonnage is large, and the mold manufacturing cost is high. The amount of concave rebound is large, it is difficult to control and easy to twist, and the surface quality is not high

Embodiment 1

[0024] Take the front longitudinal beam of auto parts as an example; adopt the molding process method of stamping die beam parts of the present invention to produce a set of automobile beam parts, comprising the following steps:

[0025] 1) The material of the part is unfolded, and the approximate initial size of the material is obtained, which is controlled within 1-5 mm. The initial material of this shape is used for debugging, and the blanking line of the part is obtained, and the blanking and layout are discharged according to the shape, and the blanking is manufactured. material mold; (see attached Figure 1-3 ) After the trimming line of the workpiece is determined by the mold trial, reasonable layout is used to save materials, the present invention is as follows: image 3 The part blanking layout shown in the figure, because the workpiece is composed of three sections of materials with different thicknesses welded, so there are three layouts, one layout for each section...

Abstract

The invention relates to the field of punching dies, in particular to a forming process of a punching die beam piece. The method comprises the following steps of: 1. expanding the material of a workpiece to obtain rough material initial dimensions, wherein the dimensions are controlled to be less than 1-5mm; carrying out debugging with the initial material of the shape to obtain a blanking line of the workpiece; and arranging blanking stock layouts according to the shape to manufacture a blanking die; 2. forming: debugging the creases, the cracks, the overlaps, the instability and the surface quality of the workpiece; 3. side reshaping: reshaping the whole profile, and correcting the springback of the last process; and 4. trimming and punching holes: punching the hole of the workpiece and trimming.

Description

technical field [0001] The invention relates to the field of stamping dies, in particular to a forming process method for beams of the stamping die. Background technique [0002] The increasingly fierce competition in the automobile industry, the increase in production capacity, the shortening of the new car research and development cycle, and the shortage of raw materials have directly affected the mold industry. As an important part of the automobile, beam parts are particularly important. This model has been used by some automobile manufacturers for a long time, and among the highly interchangeable auto parts, the front and rear side beams bear the brunt, so the demand for such parts is very large. Frequent places are also one of the important directions of automobile development. In the overall safety performance of automobiles, the requirements for beam parts that play a key role are getting higher and higher. Changing to thick materials, high-strength plates, etc., ha...
