Description

Technical Field

[0001] The utility model belongs to the technical field of metal processing, in particular to an expansion riveting device for metal parts of an automobile radiator. Background Art

[0002] Metalworking, also known as metalworking, refers to the production activities of humans processing materials with metallic properties that are composed of metal elements or mainly composed of metal elements. It is a process technology that processes metal materials into objects, parts, and components, including large parts such as bridges and ships, and even small components of engines, jewelry, and watches. It is widely used in different fields such as science, industry, art, and handicrafts. In the field of metalworking, it includes a device for riveting metal parts of automobile radiators.

[0003] For example, a Chinese patent application with publication number CN221538783U discloses a riveting device for metal parts of an automobile radiator, comprising a base, a bracket welded to the upper end of the base, a rotary punching riveting mechanism mounted on the bracket, a punch fixedly connected to the upper end of the base, a workpiece placed on the punch, and an insert slidably connected within the workpiece. The present invention provides a punch on the base to support the workpiece and a riveted insert sleeve on the workpiece, and then provides a rotary punching riveting mechanism on the bracket of the base. A motor and a hydraulic cylinder are used to simultaneously control the lifting and rotation of the riveting head, thereby enabling rotary punching of the insert sleeve, resulting in a better riveting effect on the workpiece.

[0004] Referring to the above-mentioned prior art, since the hydraulic cylinder is arranged on one side, it will cause the linkage disk to tilt to one side when applying downward force. Since the square shaft and the sleeve are linked to the linkage disk, the output shaft of the motor and the motor will be deformed due to the pressure, thereby causing damage to the motor, and thus failing to ensure effective riveting of the radiator metal parts.

[0005] To this end, we provide a car radiator metal parts expansion riveting device to solve the above problems. Utility Model Content
