Abstract

The invention relates to a cold stamping die. A hydraulic device is arranged on the top of an upper die holder (1) of the cold stamping die, and the bottom of the upper die holder (1) is fixedly connected with an upper die body through a fixed base; a lower die body is fixed on the top of a lower die holder (2) of the cold stamping die, the upper die body is provided with a stripper plate, a side punching wedge slider (3) is connected with a side punch (32), and can move on the upper die holder (1) under the action of a first driving block (21), and the cold stamping die is characterized by also comprising a wedge mechanism (8) which is arranged on the upper die holder and the lower die holder. In the downward motion process of the upper die holder (1), the wedge mechanism (8) is first triggered to move, so that a side shaping insert (86) acts on a shaped part (52) of a stamped part (5), the side punching wedge slider (3) is then triggered, so that the side punch (32) acts on a punched part (51) of the stamped part (5) in the end, and thereby shaping and punching are complete in the same process.

Description

technical field [0001] The invention relates to a cold stamping die. Background technique [0002] Cold stamping dies are mostly special tools installed on a press to apply deformation force at room temperature to obtain product parts of a certain shape, size and performance. [0003] For stamping parts, different height positions of stamping parts may require different stamping treatments, such as side shaping and punching in different parts. When the existing cold stamping die is used for stamping, there are the following technical defects: the existing cold stamping die processes different parts of the stamping parts separately, which will increase the stamping process steps, and stamping different parts separately may cause deformation of different parts, affecting the The quality and precision of stamping parts. [0004] Chinese patent: A side shaping mechanism to solve the side rebound of stamping parts, application publication number: CN102699148A, discloses a side ...
