Abstract

The invention discloses a pressing-riveting punching die. The pressing-riveting punching die comprises a cushion block fixedly arranged on an upper die, a rivet fixing block, a rivet and a riveting female die. The rivet fixing block is provided with a fixed installing part and a rod part. The fixed installing part is connected with the cushion block, one end of the rod part is connected with the fixed installing part, and an installing groove is formed in the other end of the rod part. The rivet is arranged in the installing groove, and a first pressing-riveting structure is formed on the rivet. The riveting female die is fixedly arranged on the lower die, and a second pressing-riveting structure facing the rivet and matched with the first pressing-riveting structure is formed by the riveting female die. In the pressing-riveting punching die, the cushion block is arranged on the upper die, the riveting female die is arranged on the lower die, and workpiece riveting is achieved through cooperation of the rivet fixing block arranged on the cushion block, the rivet on the cushion block and the riveting female die; the rivet is fixed into the installing groove through the air pressure, the pressing-riveting punching die is convenient and flexible to use, replacement is easy, plastic deformation of the workpiece is achieved through pressing-riveting via the first pressing-riveting structure and the second pressing-riveting structure, and riveting is achieved.

Description

technical field [0001] The invention relates to the field of dies, 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...
