Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] Such as Figure 1 to Figure 8 As shown, a kind of curved plate porous processing mold of the present invention comprises upper die 1, lower die 3 and presser 2, wherein the middle part of upper die 1 is provided with the mounting groove 103 of rectangular structure, and this mounting groove 103 There are two sets of inclined-plane punching mechanisms that are symmetrical to the transverse center plane of the upper die 1 fixed inside. The inclined-plane punching mechanism includes a first inclined-plane punching assembly 4, a second inclined-plane punching assembly 5, and a third inclined-plane punching assembly 6 And the fourth inclined-plane punching assembly 7, the first inclined-plane punching assembly 4 includes the first oblique wedge 401 and the first punch 402 installed on the first oblique wedge 401; the second oblique-plane punching assembly 5 includes ...

Abstract

The invention provides a mold for processing porous arc-shaped plates, which includes an upper mold, a lower mold and a presser. An installation groove is opened in the middle of the upper mold, and two groups of inclined-plane punching mechanisms are fixed in the installation groove. Two groups of inclined-plane There are 3 sets of plane punching components on the outside of the punching mechanism; the presser includes a rectangular frame and mounting parts located at both ends of the rectangular frame. The surface is provided with a plurality of through holes matching the inclined-plane punching mechanism and the plane punching assembly; the installation part is connected to the top plate of the upper die through a plurality of travel limit rods; the middle part of the upper surface of the lower die is equipped with a There are two sets of sliding guide rails matched by the mechanism, and a positioning block is arranged on the outside of the sliding guide rails, and a punching die that cooperates with the movement of the punch is arranged on the positioning block. During the punching process, the arc-shaped plate will not move, and the concave surface of the pressing block and the convex surface of the positioning block can match the structure of the arc-shaped plate to avoid secondary deformation of the arc-shaped plate during the extrusion process.

Description

technical field [0001] The invention relates to the technical field of punching processing of automobile parts, in particular to a mold for processing holes in an arc-shaped plate. Background technique [0002] In automobile manufacturing, for the sake of the appearance of the whole car, many arc-shaped parts on the car body are used, and the arc-shaped plate needs to have mounting holes and buckle holes on the inclined plane and the plane during installation. The processing method is to fix the arc-shaped plate through the tooling, then process the holes on the inclined plane or the plane, and then reverse the direction of the arc-shaped plate, and process the holes on the other inclined plane or plane. Although the existing hole processing Both adopt the punching method, but the holes on the inclined plane and the plane cannot be processed at the same time, and the arc-shaped plate needs to be positioned multiple times, and the irregular arc-shaped plate cannot be accurate...
