Novel riveting die

Abstract

The invention relates to a novel riveting die which comprises an upper die body and a lower die body. The upper die body comprises a stripper plate and an upper die punch pin. A first riveting boss isarranged on the end portion of the upper die punch pin. The stripper plate is provided with a first through hole matched with the upper die punch pin. The lower die body comprises a lower die plate and a lower die punch pin. A second riveting boss is arranged on the end portion of the lower die punch pin. The width of the second riveting boss is smaller than that of the first riveting boss. The lower die plate is provided with a second through hole matched with the lower die punch pin. In the die closing process of the die, riveting is directly carried out by means of the pressure effect of the upper die punch pin and the lower die punch pin, in the riveting process, a workpiece deforms under extruding of the first riveting boss, the deformation portion is extruded into the areas of the two sides of the second riveting boss to complete riveting, the riveting effect is good, the two working procedures are saved, the production efficiency is improved, the overall structure is simple, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of hardware molds, and more specifically, relates to a novel riveting mold. Background technique [0002] Riveting refers to the rivet connection of two or more workpieces. In the production of hardware, molds are usually used to rivet two or more workpieces through the clamping pressure of the upper and lower molds; at present, when using molds for riveting processing , It is necessary to punch a salad hole in one product first, turn over the pig’s mouth in another product, and then close the mold and rivet. It requires three processes for production, and the production efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new riveting die with high production efficiency in view of the above defects of the prior art. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] Con...
