Abstract

The invention discloses a fine-pressed brake shoe and a preparation method thereof. The fine-pressed brake shoe includes a rib plate and a panel, the rib plate is arc-shaped, and the panel mounting surface is in the same shape as the rib plate mounting surface. Cooperate; the mounting surface of the rib plate is provided with a raised positioning block, the panel is provided with a positioning hole penetrating the panel, the positioning block passes through the positioning hole, and the rib plate and the panel are fixedly connected by precision pressing and crimping. The fine-pressed brake shoe has few manufacturing processes, simple process, short production cycle, time-saving and labor-saving, less production equipment configuration requirements, no time-consuming equipment such as welding and boring, and uses fine pressing to fix the panels and ribs. The connection of the plates not only ensures the accuracy and strength of the whole brake shoe, but also greatly increases the appearance quality of the whole brake shoe.

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...
