Abstract

The invention discloses a coining type brake shoe and a manufacturing method thereof. The coining type brake shoe comprises rib plates and a face plate. Each rib plate is in an arc shape, and the mounting surface of the face plate is matched with the mounting surface of each rib plate in shape. Raised locating blocks are arranged on the mounting surface of each rib plate, locating holes for penetrating through the face plate are formed in the face plate, and the locating blocks penetrate through the locating holes. The rib plates and the face plate are fixedly connected in coining and pressure welding modes. The coining type brake shoe is simple in manufacturing process, simple in technology, short in production cycle, saving in time and labor, and small in production equipment layout requirement; the time-consuming and equipment-consuming working process such as welding and boring does not exist, the face plate and the rib plates are fixedly connected in a coining mode, the precision and strength of the entire brake shoe are guaranteed, and the appearance quality of the entire brake shoe is also greatly improved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a precision-pressed brake shoe and a preparation method thereof. Background technique [0002] The brake is one of the important parts of the car, which is directly related to the braking performance and safety of the car. The brake shoes of traditional brakes are cast by castings and then finished by machining. Casting brake shoes have many disadvantages: rough appearance, bulky products, unstable casting quality, fast wear and tear and easy cracking, large production energy consumption, high processing costs, large heat capacity, difficult heat dissipation, and high labor intensity of workers. Modern auto parts need to be developed in the direction of lightweight, safety and environmental protection. [0003] The stamped and welded brake shoe is a structure in which two rib plates and one panel are welded together. Compared with the cast brake shoe, it has the characteristics of sim...
