Abstract

The invention relates to a brake pad preparation method. The brake pad preparation method comprises steps as follows: a1, a plate for preparing a back plate of the brake pad is subjected to blanking, so that a base plate part of the back plate of the brake pad and multiple extending parts connected with the outer edge of the base plate part are formed by the plate; a2, a friction material for preparing a friction plate is subjected to press fit forming on the base plate part; a3, the extending parts are folded towards the base plate part, the tail ends of the extending parts are attached to or propped against the base plate part, so that a brake pad back plate structure provided with multiple hollow supporting cavities is formed, and the problems of complicated preparation technology and large mass of a conventional brake pad are solved.

Description

technical field [0001] The invention relates to the technical field of brake pads, in particular to a method for preparing a brake pad with a thickened back plate. Background technique [0002] Brake pads are one of the indispensable parts in auto parts, and they are also a kind of safety parts. It mainly plays the role of stopping the moving car. [0003] In order to ensure a good braking effect, the back plate of the brake pad needs to have good mechanical strength; at the same time, in order to reduce the weight of the vehicle, the brake pad needs to adopt a lightweight design. [0004] The patent of invention with the publication number CN101648339A discloses a manufacturing process of the rolled mesh steel back. The rolled mesh liner is densely covered with stretch holes, and the rolled mesh liner and the metal back are firmly riveted or welded with bosses or rivets. together. [0005] This kind of manufacturing process adopts welding or riveting process to increase ...
