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 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
[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

Embodiment Construction

[0029] Combine below Figure 2 to Figure 6 , the present invention is further described:

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

[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.

[0032] The mounting pla...

Abstract

The invention relates to an anti-bouncing waste stamping die. A blanking knife edge is provided with an inverted-frustum-shaped blanking segment. The anti-bouncing waste stamping die is characterized in that an inlet and an outlet of the anti-bouncing waste stamping die are each provided with a stamping piece pressing limiting mechanism (A) acting on a stamping piece (10). The stamping piece pressing limiting mechanisms are arranged on a lower die base. The stamping piece pressing limiting mechanisms can not only position the stamping piece, but also press the stamping piece tightly, the stamping quality of the stamping piece is guaranteed, and even automatic safe discharging is achieved after stamping is finished.

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] 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, 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. [0004] 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...
