Abstract

The invention relates to a reverse-riveting double-head fixed column stamping die. The reverse-riveting double-head fixed column stamping die comprises an upper template, a lower template, an upper punch and a lower punch, wherein the lower template comprises a lower die bottom plate, a floating material plate arranged on the lower die bottom plate in a floating mode and a male die fixedly arranged on the floating material plate; a floating material plate punch hole and male die punch hole which are adaptive to the lower punch are correspondingly formed in the floating material plate and the male die; the bottom of the lower punch is fixedly arranged on the lower die bottom plate, and the lower punch is slidably arranged in the floating material plate punch hole and the male die punch hole; and receding grooves adaptive to the interference side of a U-shaped stamping piece are formed in the side surfaces of the lower punch and the male die. Compared with the prior art, the receding grooves are formed in the lower punch, and the interference side of the U-shaped stamping piece is placed in the receding grooves in the stamping process, so that the problem that forward riveting cannotbe carried out due to the interference of the punches and the side wall of the stamping piece is solved; and in addition, the reverse-riveting double-head fixed column stamping die has the advantagesof simple structure, convenient operation and the like, the implementation of mass processing production of parts is facilitated, and a wide application range is achieved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a reverse riveted double-head fixed column stamping die. Background technique [0002] The product riveting process usually adopts such as figure 1 The forward riveting process shown: the stamping die used generally includes an upper template 1 and a lower template 2, wherein the upper template 1 includes an upper backing plate 3 and an upper splint 5 equipped with a punch 4, and the lower template 2 is provided with a mounting groove; When working, first place one end of the double-headed fixing column 6 used for riveting and fixing in the installation groove, and then set the stamping part 7 to be riveted on the double-headed fixing column 6 and place it on the lower template 2, and position it well Finally, the upper template 1 is driven downward by the slider on the punching machine, and the head of the double-headed fixed column 3 is thickened under the impact o...
