Abstract

The invention discloses a wedge die. The wedge die includes an upper die body and a lower die body, wherein a material pressing core is arranged on the upper die body; a reverse wedge mechanism and a lower die insert matched with the material pressing core are arranged on the lower die body; a chute is formed in the material pressing core; a core pressing sliding block is arranged in the chute, and can move towards the reverse wedge mechanism under the co-action of the material pressing core and the lower die body; a core pressing wedge insert is arranged on the core pressing sliding block; a lower die wedge insert is arranged on the reverse wedge mechanism and matched with the core pressing wedge insert. The wedge die provided by the invention has the advantages that a wedge sliding block socket is jointly formed by the upper die body and the material pressing core, and the material pressing core is directly used as a driving block to guide and drive the core pressing sliding block, so that the structural space of the die is reduced, the die manufacturing cost can be saved by about 5 percent, and the deformation risk of the material pressing core is controlled for easier maintenance of a stable die status.

Description

technical field [0001] The invention belongs to the technical field of cold stamping, and in particular relates to a wedge die. Background technique [0002] The wedge mold used to complete the side trimming, side flanging and side shaping of stamping parts includes an upper mold body, a lower mold body and a wedge structure. For the current wedge structure, a slider seat is designed on the upper mold body, and the wedge slider is located in the slider seat of the upper mold body, and a driving block or a driving surface is designed on the lower mold body, so that the slider is between the upper mold and the Under the combined action of the lower mold, the movement can complete the work of side trimming, side flanging and side shaping. This kind of conventional wedge structure, for some stamping parts, will cause the size of the mold to increase, which will increase the manufacturing cost, and will also cause the structure of the pressing core to be unbalanced, resulting in...
