Abstract

The invention discloses a bevel wedge die. The bevel wedge die comprises an upper die body and a lower die body, wherein the upper die body is provided with a material pressing core, the lower die body is provided with a reverse bevel wedge mechanism and a lower die embedded block which is matched with the material pressing core, a sliding groove is formed in the material pressing core, a core pressing sliding block which can move towards the reverse bevel wedge mechanism under the combined action of the material pressing core and the upper die body is arranged in the sliding groove, a core pressing bevel wedge embedded block is arranged on the core pressing sliding block, and the reverse bevel wedge mechanism is provided with a lower die bevel wedge embedded block which is matched with the core pressing bevel wedge embedded block. According to the bevel wedge die disclosed by the invention, a bevel wedge sliding block nest base is formed by the upper die body and the material pressing core together, the material pressing core is directly used as a driving block, the material pressing core can be used for guiding and driving the core pressing sliding block, thus the structural space of the bevel wedge die is simplified, the cost for manufacturing the bevel wedge die can be reduced by 5%, the risk that the material pressing core deforms is controlled, and the state of the bevel wedge die can be more easily kept stable.

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...
