Abstract

The invention discloses an automobile die tapered wedge device which comprises a tapered wedge base, a lewisson block and a sliding block base. The top end of the tapered wedge base is provided with afirst V-shaped guide convex block arranged in an inclined mode, the outer wall of the bottom end of the lewisson block is provided with a first V-shaped groove matched with the first V-shaped guide convex block, the outer walls on the two sides of the tapered wedge base are provided with first guide sliding grooves formed in an inclined mode, the two sides of the bottom end of the lewisson blockare provided with guide clamping blocks matched with the first guide sliding grooves in specification, the two guide clamping blocks are movably connected with the inner walls of the first guide sliding grooves, and the top end of the lewisson block is provided with a second V-shaped guide convex block arranged in an inclined mode. The centering guiding effect of the tapered wedge device during sliding is improved, bad friction caused by component dislocation is reduced, the service life of the tapered wedge device is prolonged, the application range of the device is widened, device reset is better facilitated through a nitrogen spring arranged in a matched mode, replacement and maintenance are convenient, the maintenance cost is reduced, and the using cost is saved.

Description

technical field [0001] The invention relates to the technical field of wedge devices, in particular to a wedge device for an automobile mold. Background technique [0002] The oblique wedge is used for lateral punching of automobile molds and is an irreplaceable device in the production of automobile panels. However, as automobile OEMs gradually increase the safety requirements for automobile use, high-tensile steel plates have begun to be used by automobile mold factories. [0003] Disadvantages of traditional wedges: poor stability, low strength, when stamping high-strength steel plates, the main body will break, the pull-out force is insufficient, and the maintenance cost is high. So now a kind of automobile mold wedge device is proposed. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings in the prior art, and propose an automobile mold wedge device. [0005] In order to achieve the above object, the present invention ...
