A high-precision anti-jump waste stamping die

Abstract

The invention relates to a high-precision stamping die capable of preventing waste materials from jumping. A punching tool edge is provided with a punching section in an inverted frustum shape. The high-precision stamping die is characterized in that an inlet and an outlet of the stamping die capable of preventing the waste materials from jumping are each provided with a stamped part pressing and limiting mechanism (A) which acts on a stamped part (10). Due to the fact that the inlet and the outlet of the stamping die capable of preventing the waste materials from jumping are each provided with the stamped part pressing and limiting mechanism, the stamped part pressing and limiting mechanisms can act on the stamped part in the horizontal direction and the perpendicular direction, the stamped part is well limited and fixed, and thus the obtained stamped product is higher in precision and quality.

Description

technical field [0001] The invention relates to an anti-jumping waste stamping die, in particular to an anti-jumping waste stamping die which can improve stamping precision. Background technique [0002] Stamping die is a commonly used manufacturing equipment, which can be used for stamping and forming of metal parts. However, the existing stamping dies have the situation of jumping waste, that is, the waste jumps out from above the lower die. When stamping continuously, jumping waste can easily lead to mold damage. [0003] Chinese patent anti-jump waste stamping die, patent application publication number CN104028616A, although solved the problem that jump waste easily causes mold damage, but itself also includes guide rod 9 because upper mold, guide rod 9 is fixedly connected with upper mold base 1, and Slidingly matched with the stripping assembly, the lower mold is also provided with a guide post hole 19 matched with the guide rod 9 . Specifically, the lower end of th...

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

[0003] Chinese patent anti-jump waste stamping die, patent application publication number CN104028616A, although solved the problem that jump waste easily causes mold damage, but itself also includes guide rod 9 because upper mold, guide rod 9 is fixedly connected with upper mold base 1, and Slidingly fit with the stripping assembly, the lower mold is also provided with a guide post hole 19 matched with the guide rod 9

[0004] 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
