Abstract

The invention relates to the technical field of dies, and provides a die. The die comprises a male die and a female die matched with the male die; the male die comprises a die core and a material pressing face surrounding the edge of the bottom end of the die core; protruding ribs are arranged on the front side wall of the die core, and the protruding ribs extend to the bottom end of the die corealong with the top end of the die core; and the surfaces of the protruding ribs are cambered surfaces, and the surfaces of the protruding ribs are smoothly connected with the front side wall of the die core. According to the die, when a plate is machined, the plate is stamped through the cooperation between the male die and the female die, so that the plate is plastically deformed and formed; andwhen the plate is wrapped around the front side wall of the die core, due to the fact that the protruding ribs form protruding portions protruding outwards on the plate when the plate is stamped, usedmaterials of the plate are increased, and the situations of wrinkling and folding caused by excessive local accumulation of the plate in the stamping process of the plate are avoided.

Description

technical field [0001] The invention belongs to the technical field of molds, and more specifically relates to a mold. Background technique [0002] In the process of sheet metal parts processing, the sheet is stamped by the punch and the die, so that the sheet is plastically deformed to form the shape of the desired product. During the deformation process of the sheet, usually after the product is formed (usually the product is formed on the top wall of the punch), the end of the punch (end: such as the front side wall of the punch / punch core) will appear, In the process of wrapping the end of the sheet, it is easy to cause the sheet to wrinkle and overlap due to too much local sheet. Contents of the invention [0003] The purpose of the present invention is to provide a mold to solve the technical problem existing in the prior art that the boards are easily wrinkled and stacked due to excessive local boards during the process of wrapping the ends with boards.
