Stamping die used for sideward push

Abstract

The invention discloses a stamping die used for sideward push. An elastic pressing block is arranged above an insert core. A first inclined wall is arranged on one side of the insert core. When the insert core is in the initial position, one end of the first inclined wall and one side of the elastic pressing block are aligned in the vertical direction. A punch pin is arranged on one side of the elastic pressing block. A second inclined wall is arranged on one side of the punch pin. The second inclined wall and the first inclined wall are parallel to each other. A third inclined wall is arranged on the other side of the insert core. A push rod is arranged above the third inclined wall. A fourth inclined wall parallel to the third inclined wall is arranged at the bottom of the push rod. Due to the first inclined wall, a bent edge used for conveniently bearing force is formed on the top of the insert core, and meanwhile enough bending space is reserved for a bent piece. Due to the second inclined wall, bending resistance between the punch pin and a plate is reduced. Due to the third inclined wall and the fourth inclined wall, the insert core can slide towards one side of the punch pin in the die assembly process so that a bent angle smaller than 90 degrees can be formed. The stamping die is simple in structure, stable and reliable in bending and capable of effectively reducing bending resistance.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a stamping die for side pushing. Background technique [0002] In the bending die of the prior art, during the stamping process, because the outer wall of the punch has a large contact area with the sheet material, there is a large bending resistance, which easily scratches the surface of the sheet material. At the same time, due to the entry The side wall and the top surface are set vertically, so the sheet metal is easy to rebound and not easy to bend after bending. In addition, for the bending of workpieces with a bending angle of less than 90 degrees, the general mold structure design is more complicated, so the mold The cost is relatively high. Contents of the invention [0003] The purpose of the present invention is to provide a stamping die with simple structure, stable and reliable bending, and effective reduction of bending resistance. [0004] For reaching th...
