Fin trimming device for steering wheel of automobile

Abstract

A fin trimming device for a steering wheel of an automobile belongs to the technical field of molds and comprises an upper mold mechanism and a lower mold mechanism matched with the upper mold mechanism. The upper mold mechanism comprises an upper mold frame, a cutter fixing board, a group of outer ring cutter blocks, a group of inner ring cutter blocks and a spoke rim pressing ring. The lower mold mechanism comprises a lower mold frame, a spoke cutter fixing board, a plurality of groups of spoke cutters, a gasket board, a group of spoke rim pressing ring gaskets and a group of spoke pressingblock gaskets. The fin trimming device has the advantages of being capable of not only saving labor input and reducing working intensity of workers but also remarkably improving eliminating efficiency and effect on fins.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to an automobile steering wheel burr repairing device. Background technique [0002] As is well known in the industry, whether it is extrusion molding, die casting molding or other similar methods such as casting, the steering wheel of the car will leave process flashes, which are also called process waste edges and must be removed. Furthermore, as known in the industry, the steering wheel of an automobile is composed of an annular ring, a spoke seat and spokes, the spoke seat is generally located in the center of the annular ring, and the spokes are connected between the spoke seat and the annular ring. Although there are differences in the steering wheels of different vehicles, the macrostructure is basically the same, that is, they all have annular rings (also known as spoke rims), spoke seats and spokes, but the spokes have two in-line distributions or generally in th...

Problems solved by technology

It is for this reason that there are very few technical information about the trimming device of the automobile steering wheel in the patents and non-patent literatures that have been disclosed at present. Only CN201760487U recommends "a kind of trimming mold for the automobile steering wheel". Although this patent scheme It has the technical effect mentioned in paragraph 0007 of its description, but it can only remove the burrs on the outer edge of the annular ring of the steering wheel, but it can't do anything about the inner edge of the annular ring and the burrs on the spokes, and in this patent specification There is no inspiration for removing these flash edges
