Arc plate porous machining mold

Abstract

The invention provides an arc plate porous machining mold. The arc plate porous machining mold comprises an upper mold, a lower mold and a material press; a mounting groove is formed in the middle part of the upper mold; two sets of inclined surface punching mechanisms are fixed in the mounting groove; three sets of plane punching modules are arranged on the outer sides of the two sets of inclinedsurface punching mechanisms; the material press comprises a rectangular frame, and mounting parts positioned at two ends of the rectangular frame; pressing blocks with arc structures are arranged attwo ends of the rectangular frame; multiple via holes matched with the inclined surface punching mechanisms and the plane punching modules are formed in the top surfaces of the pressing blocks; the mounting parts are connected to a top plate of the upper mold through multiple travel limiting rods; two sets of slide guide rails matched with the inclined surface punching mechanisms are arranged at the middle part of the upper surface of the lower mold; positioning blocks are arranged on the outer sides of the slide guide rails; and the positioning blocks are provided with punching concave moldscapable of moving through matching with punches. In the punching process, arc plates cannot move, and concave surfaces of the pressing blocks and concave surfaces of the positioning blocks can be matched with the structures of the arc plates, so that secondary deformation of the arc plates caused by the extrusion process is prevented.

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...
