Riveting process suitable for die-cast piece

Abstract

The invention discloses a riveting process suitable for a die-cast piece. The riveting process is characterized by comprising the following steps: 1) a first layer of workpiece and a second layer of workpiece are provided, and are placed up and down in sequence to form a piece to be riveted; 2) a bearing mold is provided; and the piece to be riveted is put in the bearing mold; 3) the piece to be riveted is riveted on the bearing mold; and 4) the riveted workpiece in the step 3) is machined to form a final product. The riveting process has the following beneficial effects: the process firstly rivets the two layers of workpieces, and then, performs such processes as punching, typing, trimming and burr pressing to obtain the final product; and the process arrangement guarantees the product appearance profile and the coaxiality of upper and lower holes, so that the subsequent assembly is guaranteed, and the cost is largely saved.

Description

technical field [0001] The invention relates to a riveting process suitable for die castings, belonging to the technical field of stamping riveting. Background technique [0002] At present, in the process of die-casting and molding, the riveting process in the prior art is basically to perform processes such as punching, typing, blanking, and deburring on the product. Although it is completed under the same process equipment, unless it is It is a very precise instrument, otherwise there will be some small errors more or less in the processing place, but this error will inevitably show an increasing trend with the increase of wear after the processing equipment has been used for a long time, so that It is bound to affect the quality of the product. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a riveting process suitable for die-casting parts, which can not be affected by the proce...
