Abstract

The invention provides a stamping device with a die inner side pushing and bending structure. The stamping device comprises: an upper die mechanism, wherein a punch pin is disposed on the upper die mechanism, and a first inclined face and a second inclined face are disposed at the bottom of the punch pin; and a lower die mechanism, wherein a first mounting groove is formed in the lower die mechanism, a first sliding block is arranged in the first mounting groove, one end of the first sliding block is connected into the first mounting groove through a first elastic component, a second mounting groove is formed in the first sliding block, a second sliding block is arranged in the second mounting groove, the second sliding block is connected to the first sliding block through a second elastic component, one end of the first sliding block is provided with a convex corner used for folding a negative angle, an ejector pin assembly is arranged in the convex corner, the other end of the first sliding block is provided with a third inclined face matched with the first inclined face, one end of the second sliding block is provided with a concave cavity matched with the convex corner, and the other end of the second sliding block is provided with a fourth inclined face matched with the second inclined face. Compared with the prior art, the problem that the material belt feeding is affected due to the fact that a material belt of a die floats too high can be effectively solved.

Description

technical field [0001] The invention relates to the field of stamping dies, in particular to a stamping device with a push-bending structure inside the die. Background technique [0002] In precision and high-precision stamping dies, there will be a lot of inner buckle bends, and the slope slider is usually used to form and strip the material. Often, the lower mold product must follow the slope slider to rise to a certain height before it can be stripped, such as When the depth of the inner buckle is too deep, the lower mold material belt and the slope slider will also float very high. Although this can remove the material smoothly, it affects the feeding of the follow-up material belt. Contents of the invention [0003] In view of this, the present invention provides a stamping device with a push-bending structure inside the mold, which can effectively solve the problem that the material belt of the mold is too high and affects the feeding of the material belt compared w...
