The utility model relates to a punching-welding shoe hot riveting device and a hot riveting process thereof, which are used for the hot riveting of a punching-welding shoe on an automobile service brake. An assistant cylinder jacking mechanism and a welding jig are fixed on a lower bracket of a rack, and the left side and the right side of the welding jig are respectively controlled by a cylinder 1 and a cylinder 2 and are provided with electrodes; a welding cylinder, an arc-shaped left compress part and an arc-shaped right compress part are arranged on an upper bracket of the rack, the arc-shaped left compress part and the arc-shaped right compress part are respectively controlled by a cylinder 3 and a cylinder 4, and the lower part of the welding cylinder is provided with an electrode tip; a servo-controlled motor is controlled by a welding controller, and the servo-controlled motor is connected with the welding jig through a gear mechanism; and the electrode tip of the welding cylinder is connected with an electric conduction system, and a secondary rectifier and transformer of the electric conduction system are connected with the welding controller. According to the invention, for assemblies and hot riveted parts, a complete, efficient, environment-friendly and low-cost punching-welding shoe hot riveting assembly process is formed, the weight is light, the precision is high, the influence of residual stress of a welding shoe assembly is overcome, and the working stability of the brake is improved.
Description
technical field [0001] The invention relates to the technical field of the automobile industry, in particular to a hot riveting process for stamping and welding hooves on automobile running brakes. Background technique [0002] With the rapid development of the global economy, saving energy, reducing consumption, and reducing pollution have become an inevitable and urgent need for the development of the automobile industry. Due to the large casting pollution, traditional drum brake casting shoes are increasingly unsuitable for energy saving and consumption reduction requirements. They have been gradually replaced by a new type of stamped and welded brake shoe. The stamped and welded brake shoe is 25% lighter than the cast shoe of the same specification. -30%, can realize quick replacement, easy maintenance and replacement, and is good for environmental protection. Existing stamping and welding brake shoe adopts following three kinds of processes: [0003] 1. Seam welding: ...
