One-step negative angle structure bending forming die

Abstract

The invention discloses a one-step negative angle structure bending forming die. The one-step negative angle structure bending forming die comprises an upper die mechanism and a lower die mechanism; the upper die mechanism comprises an upper die base and an upper stripper plate, the upper stripper plate is elastically connected to the upper die base, a right-angle forming assembly and a negative-angle forming assembly are further arranged at the bottom of the upper die base, and the right-angle forming assembly and the negative-angle forming assembly are symmetrically arranged on the two sides of the upper stripper plate; the lower die mechanism comprises a lower die base and a lower base plate, the lower base plate is fixedly arranged on the lower die base, and a lower die forming assembly corresponding to the upper stripper plate in position is arranged on the lower base plate; and a workpiece is placed on the lower die forming assembly, a lower ejector rod is arranged below the lower die forming assembly and elastically connected to the lower die base, and a wedge slotting tool is further arranged on one side of the lower die forming assembly and fixedly arranged on the lower base plate. According to the one-step negative angle structure bending forming die, a bent angle and a right angle are formed in one step, the machining quality is improved, and materials and die cost are saved.

Description

technical field [0001] The invention belongs to the field of metal stamping dies, in particular to a one-step negative angle structure bending forming die. Background technique [0002] The stamping process is a metal processing method, which is based on the plastic deformation of the metal, using the mold and stamping equipment to exert pressure on the sheet, so that the sheet is plastically deformed or separated, so as to obtain a product with a certain shape, size and performance. Component. [0003] The traditional negative angle bending process generally needs to be divided into two processes. The first process is to bend the material to form a right angle, and the second process is to bend the material that has been folded into a right angle to form a negative angle again. In such a negative angle folding process, the material forming efficiency is low, and the material needs to be positioned repeatedly, which affects the processing accuracy.
