Integrated display backboard drawing and bending die

Abstract

The invention discloses an integrated display backboard drawing and bending die and relates to the technical field of sheet metal part punching. The die comprises an upper die body and a lower die body, wherein the upper die body comprises an upper die base, an upper clamp plate and an upper die plate which are connected in sequence from top to bottom, a first elastic part is connected between the upper die base and the upper die plate, the upper clamp plate is fixed below the upper die base, a plurality of drawing punches are fixed to the upper clamp plate and penetrate through the upper die plate, and four bending punches are fixedly arranged on the front edge, rear edge, left edge and right edge of the bottom of the upper die plate; the lower die body comprises a lower die base and a lower die plate fixed above the lower die base, a plurality of drawing grooves matched with the drawing punches are formed in the lower die plate, and bending grooves matched with the bending punches are formed in the top of the lower die plate. Drawing and bending are achieved at a time, operation processes are simplified, the number of dies is reduced, production cost is reduced, working efficiency is improved, and continuous production can be achieved.

Description

technical field [0001] The invention relates to the technical field of stamping processing of sheet metal parts, in particular to an integrated display backplane drawing tooth bending die. Background technique [0002] Sheet metal parts are widely used in various fields in our production and life. The processing of sheet metal parts includes blanking, punching, deep drawing, tooth extraction, riveting and bending, etc., and each process is equipped with corresponding mold for production. [0003] Most of the existing all-in-one display backplanes are sheet metal parts, and their structures are as follows: figure 1 As shown, the middle part of the back panel of the display is provided with a plurality of extraction holes, and the four edges are folded with bends; the production process is generally to punch out the extraction pre-punching holes on the plate with a punching die, and then Use the drawing die to turn the material around the pre-punched hole into a side flange ...
