Pressure riveting stamping die

Abstract

The invention discloses a rivet pressing stamping die. The rivet pressing stamping die comprises a cushion block, a rivet fixing block and a riveting female die, wherein the cushion block is fixedly arranged on an upper die; the rivet fixing block is provided with a fixing and assembling part and a rod part; the fixing and assembling part is connected with the cushion block; one end of the rod part is connected with the fixing and assembling part, and the other end is provided with an assembly groove used for assembling the rivet; the riveting female die is arranged on a lower die; the top surface, facing to the rivet fixing block, of the riveting female die is provided with a through hole through which the rivet can penetrate and a boss surrounding the through hole; the cushion block is arranged on the upper die, and the riveting female die is arranged on the lower die; the rivet which is arranged on the rivet fixing block which is arranged on the cushion block is matched with the riveting female die, so that riveting of a workpiece is realized; the riveting can be directly realized by assembly of the upper die and the lower die of a current die, so that the riveting technique is applied to other techniques which are realized through assembly of the upper die and the lower die such as punching, edging, stamping and the like; and meanwhile, the rivet is fixed in the assembly groove through air pressure, so that the rivet pressing stamping die is convenient, flexible and easy to change.

Description

technical field [0001] The invention relates to a die, in particular to a riveting stamping die. Background technique [0002] With the increasingly urgent requirements of the automobile industry for lightweight and environmental protection of automobiles, new materials such as aluminum alloys and high-strength steels are gradually used in body manufacturing, and the requirements for the joining technology and process of body panels are also getting higher and higher. Traditional sheet metal connection methods such as electric welding and bolt connection have problems such as poor surface quality, easy corrosion, and even inability to achieve welding. For example, spot welding has a high temperature during the welding process, which is prone to thermal deformation and damages the original coating on the surface of the plate, making it difficult to meet the surface quality of the parts, and it is difficult to achieve welding of different materials such as aluminum alloy and s...
