Outward-turning bending die for strip-shaped piece

Abstract

The outward-turning and bending die comprises modules, the modules comprise an outer module and an inner module, the top of the outer module comprises a pair of inclined plates arranged in a mirror image mode, and the distance between the tops of the two inclined plates is larger than the distance between the bottoms of the two inclined plates; the two inner modules are arranged between the two inclined plates in a mirror image mode, and the cross section track of each inner module is in an L shape. The elastic piece comprises a transverse pressure spring and a vertical pressure spring; a guide column penetrating through the inclined plate is fixed on the inner module, and a transverse pressure spring is sleeved on the guide column; the vertical pressure spring is arranged in the outer module and below the inner module, and a jacking block in contact with the bottom of the inner module is arranged at the top of the vertical pressure spring; and the transverse pressure spring and the vertical pressure spring provide outward turning elastic potential energy for the two inner modules. By means of interaction of the transverse compression spring and the vertical compression spring, large elastic potential energy is provided, and blockage caused by discharging is avoided. The transverse compression springs are pulled towards the two sides, the vertical compression springs are ejected upwards, and the requirement for the elastic force of each compression spring is low.

Description

technical field [0001] The invention relates to the field of moulds, in particular to an eversion bending mold used for strips. Background technique [0002] The bending dies for long workpieces are also relatively long. After stamping and bending, such dies will have an eversion action, which will cause the finished product to be stripped after bending. However, the longer the size of the long workpiece, the more uncontrollable factors such as overall deformation, and sometimes the phenomenon of poor stripping of the long workpiece. Contents of the invention [0003] The problem to be solved by the present invention is to provide an eversion bending mold for bar-shaped parts. The horizontal compression spring interacts with the vertical compression spring to provide greater elastic potential energy and avoid discharge jamming. The horizontal compression spring pulls to both sides, and the vertical compression spring pushes up, so the requirement for the elastic force of ...
