Scrap-jumping prevention stamping die stamping method

Abstract

The invention relates to a scrap-jumping prevention stamping die stamping method. A blanking tool edge is provided with a blanking section in the shape of an inverted circular truncated cone. The scrap-jumping prevention stamping die stamping method is characterized in that an inlet and an outlet are each provided with a stamped part compaction limiting mechanism (A), wherein each stamped part compaction limiting mechanism (A) acts on a stamped part (10). The stamped part compaction limiting mechanisms are arranged on a lower die base, and the stamped part compaction limiting mechanisms can not only position the stamped parts but also compact the stamped parts, guarantee the stamping quality of the stamped parts, and even play an automatic safe discharge role after stamping is completed.

Description

technical field [0001] The invention relates to a stamping method of an anti-jumping waste stamping die, in particular to a stamping method of an anti-jumping waste stamping die which can improve stamping precision. Background technique [0002] There is still no tool in the existing market that realizes the three functions of pressing, limiting and unloading stamping parts in one. Therefore, too many components will lead to waste of space in the mold and reduce stamping efficiency. [0003] Stamping die is a commonly used manufacturing equipment, which can be used for stamping and forming of metal parts. However, in the existing stamping die, there is a situation where the waste material jumps out, that is, the waste material jumps out from above the lower die. When stamping continuously, skipping scraps can easily lead to die damage.

AI Technical Summary

Problems solved by technology

However, the existing stamping dies have the situation of jumping waste, that is, the waste jumps out from above the lower die

When punching continuously, jumping waste can easily lead to mold damage

[0004] Chinese patent stamping method for anti-jumping scrap stamping die, patent application publication number CN104028616A, although it solves the problem that the skipping scrap is easy to cause mold damage, but the upper mold itself also includes a guide rod 9, which is fixedly connected with the upper die base 1 , and is slidingly matched with the stripping assembly, and the lower mold is also provided with a guide post hole 19 matching with the guide rod 9

[0005] Therefore, the influence of the setting of the guide column on the stamping part requires a corresponding passage hole on the stamping part. The diameter of the passage hole is usually larger than the diameter of the guide post, and the stamping part will be displaced during the stamping process, which affects the stamping accuracy

If the guide column does not pass through the stamping part, the stamping part is prone to horizontal deviation during the stamping process, resulting in errors and unable to achieve stamping accuracy
