Abstract

The invention discloses a forming method for stamping parts. The forming method is applicable to formation of the stamping parts of a 1 / 4 box structure. According to the forming method, four parts are drawn jointly, and the method mainly comprises the steps of blanking, drawing, first trimming, first punching, center separation, second punching and second trimming. According to the forming method, the four parts are drawn jointly, so that the stamping parts of the 1 / 4 box structure are easier to form; drawn sheets are arrayed on a strip material, and thus the utilization rate of raw materials can be effectively improved; by adoption of the stepped trimming and punching processes, the stamping parts can be positioned accurately in the subsequent procedures; and the forming method can form four stamping parts each time, thereby having high production efficiency.

Description

technical field

[0001] The invention relates to a part forming method, in particular to a stamping part forming method. Background technique

[0002] In the automobile manufacturing process, it will be applied to some such as figure 1 The stamping part 1 of the shell shown is a quarter box-shaped structure, and its side and bottom surface need to be processed with process holes, such as the door sill connecting plate of a certain model, and the left and right sills are usually connected. The plates are symmetrical to each other.

[0003] If the stamping part 1 is processed according to the conventional stamping forming process, that is, single-piece forming or left and right parts are combined and formed, it is often difficult to position the stamping part 1 when performing subsequent processes such as punching, and then the stamping part 1 The overall forming of the mold is difficult and cannot meet the quality requirements of stamping parts; and the conventional stamping...

Embodiment Construction

[0028] The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0029] Embodiment of the present invention: a method for forming a stamping part. For ease of understanding, the stamping part 1 selected in this embodiment is as follows figure 1 The sill connecting plate of the quarter box structure shown, and the left and right sill connecting plates are symmetrical structures, and the side and bottom surfaces need to be processed with process holes. In the forming method, four stamping parts 1 are combined and stretched together, and the four stamping parts 1 are combined in pairs. The process mainly includes several processes such as blanking, stretching, trimming and punching, and is carried out according to the following steps:

[0030] 1. Blanking, according to the size of the stamping part 1, determine the size of the stretched sheet 2 required for ...
