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
[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

Embodiment Construction

[0029] Combine below Figure 2 to Figure 5 , the present invention is further described:

[0030] Such as figure 2 As shown, the present invention provides a high-precision anti-jump waste stamping die, which includes an upper die and a lower die that can move relative to each other up and down.

[0031] The upper mold includes an upper mold base 1, a stripper assembly, an elastic element 8, a mounting plate and a punch 7. The upper mold base 1 and the stripping assembly are connected through a connecting element 2, and the upper mold base 1 and the stripping assembly can move up and down relative to each other. The stripping assembly includes a stripping plate 6 and a sub-baffle 5, and the stripping plate 6 is fixedly connected under the sub-baffle 5 for pressing materials. The connecting element 2 is a bolt, one end of which is connected with the upper mold base 1, and the other end passes through the mounting plate and is connected with the sub-baffle 5.

Abstract

The invention relates to a high-precision stamping method for an anti-tripping waster material stamping die. A stamping cutter edge is provided with an inverse frustum-shaped stamping section. The method is characterized in that a stamping component compressing and limiting mechanism (A) which acts on a stamping component (10) is arranged at each of an inlet and an outlet of the anti-tripping waster material stamping die. Due to the fact that one stamping component compressing and limiting mechanism is arranged at each of the inlet and the outlet of the anti-tripping waster material stamping die and can act on the stamping component in both the horizontal direction and the vertical direction, the stamping component can be well limited and fixed, and a stamped product is higher in precision and quality.

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] 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 ...
