Embodiment Construction

[0030] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] Such as Figure 4 As shown, a stamping punch for automobile beams provided by the embodiment of the present invention includes a base 25 on which an axially extending punch body 24 is arranged, and the base 25 is located on both sides of the punch body 24. It has a stamping surface, at least one of the two stamping surfaces is provided with a stamping deformation part extending along the axial direction, and the stamping deformation part is used to deform the sheet metal part attached to the stamping surface during stamping.

[0032] Specifically, the stamping punch and the stamping die cooperate to punch out the beam parts of the car. The beam parts can be beams, longitudinal beams and reinforcing beams at any position on the car, such as...

Abstract

The invention discloses a stamping male die for car beam parts and a stamping forming method. The stamping male die comprises a base, the base is provided with an axially-extending male die body, stamping faces are arranged at the position, located on the two sides of the male die body, of the base, and at least one of the two stamping faces is provided with stamping deformation parts extending in the axial direction; and the stamping deformation part is used for enabling sheet metal parts attached to the stamping face to deform during stamping. By means of the stamping male die, the stamping deformation parts extending in the axial direction are arranged on the two sides of the male die body, enable extending plates of two wings of a beam body to deform during stamping, and enable plates to sufficiently flow, so that the internal springback stress is reduced, and the springback probability of the beam parts is accordingly reduced.

Description

technical field [0001] The invention relates to automobile manufacturing technology, in particular to a stamping punch and a stamping forming method for automobile beam parts. Background technique [0002] Beam parts are the basic components of the car frame, such as the beams and longitudinal beams of the frame, the beams and longitudinal beams of the sub-frame, and the beams of the roof rack, etc. Beams form the backbone of the vehicle and provide the basis for mounting various components and assemblies. [0003] figure 1 It is a structural schematic diagram of beams in the prior art, figure 2 It is a structural schematic diagram of punching dies for beams in the prior art, such as figure 1 As shown, the beam-like component has an axially extending beam body 11 , the radial section of which is generally U-shaped, and two extension plates 12 are provided at both ends of the opening of the U-shaped beam body 11 . Such as figure 2 As shown, the shape of the beam stampi...
