Problems solved by technology

[0002] Rivet connection is a commonly used connection method in mechanical processing. Usually, the connection edge of the box body or shell-shaped part 70 is connected by rivets. The die used for pressing the rivet is mostly in the shape of a cantilever, and the workpiece to be processed is set on the die. , during the riveting process, the punching force on the die is relatively large, which may easily cause the bending deformation of the overhanging part of the die. In severe cases, the die will break. The unevenness of the pressing surface affects the riveting quality and makes the mold unable to use normally

Embodiment Construction

[0013] A kind of rivet pressing mold, comprises the upper template 10 is provided with the riveting punch 11, the overhanging die 30 is fixedly connected on the support 20, is provided with the spring 50 between the binder plate 40 and the upper template 10, the upper template 10 and the support 20 are provided with a guide mechanism 60, the riveting punch 11 passes through the binder plate 40 and its head forms a stamping fit with the die 30, and the overhanging part of the die 30 is provided with a support mechanism. One end of the die 30 is fixedly connected to the bracket 20 and the other end is overhanging. The workpiece to be processed is set on the die 30. The riveting punch 11 passes through the binder plate 40 and then punches the rivet to realize riveting. Among them, under the action of the supporting mechanism, the overhanging part of the die 30 offsets most of the stamping force, effectively prevents the die from being deformed, improves the quality of riveting, en...

Abstract

The invention relates to the field of dies, in particular to a rivet punching die. A riveting punch is arranged on an upper die plate, an overhanging concave die is fixedly connected to a bracket, a spring is arranged between a pressure plate and the upper die plate, a guide mechanism is arranged between the upper plate and the bracket, the riveting punch passes through the pressure plate and thehead of the riveting punch is in punching fit with the concave die, the overhanging part of the concave die is provided with a support mechanism, and the concave die counteracts most of punching force under the action of the support mechanism, therefore the deformation of the concave die is effectively improved, the riveting quality is improved, a flat riveting surface is ensured and the service life of the die is prolonged.

Description

technical field [0001] The invention relates to the field of molds, in particular to a pressure rivet mold. Background technique [0002] Rivet connection is a commonly used connection method in mechanical processing. Usually, the connection edge of the box body or shell-shaped part 70 is connected by rivets. The die used for pressing the rivet is mostly in the shape of a cantilever, and the workpiece to be processed is set on the die. , during the riveting process, the punching force on the die is relatively large, which may easily cause the bending deformation of the overhanging part of the die. In severe cases, the die will break. The uneven pressing surface will affect the riveting quality and make the mold unable to use normally. Contents of the invention [0003] The purpose of the present invention is to provide a pressure rivet die which effectively prevents deformation of the die and improves riveting quality. [0004] In order to achieve the above object, the p...
