Abstract

The invention discloses a bending punching die, which relates to a punching die for machinery processing. The punching ide comprises an upper die base, an upper clamping plate, a lower template and a lower die base, wherein the upper die base is connected with the upper clamping plate; the lower template is connected with the lower die base; the lower template is provided with a groove; the upper clamping plate is provided with a bending punch; the bending punch is provided with a V-shaped punching end which is matched with the groove of the lower template; and the top end of the bending punch is provided with a screw hole. Due to the adoption of the technical scheme, the V-shaped punch of the bending punch is matched with the groove of the lower template, bending of machine elements is realized through one-time punching, and the bending degrees of the machine elements are kept consistent.

Description

technical field [0001] The invention relates to a stamping die used for mechanical processing. Background technique [0002] Stamping machine tool is a commonly used machine in the field of metal machining. Its processing of machine parts is mainly formed by stamping with molds. For die stamping, punching, shaping, trimming and other processes are easier to complete. For some parts, the shape needs to be bent and twisted at a certain angle. In the past, the parts were usually stamped and then mechanically twisted. . But its disadvantage is that the bending camber of the twisted parts cannot be kept consistent, and the machined parts are inconsistent, which affects the performance of the parts. Contents of the invention [0003] The invention provides a bending stamping die, which can realize the turning stamping of parts. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A bending stamping die, comprising ...
