Description

Technical Field

[0001] The utility model relates to the technical field of brake pad processing, in particular to a brake pad forming and positioning tool. Background Art

[0002] Car brake pads, also called car brake leathers, refer to the friction materials fixed on the brake drum or brake disc that rotates with the wheel. The friction lining and friction pads are subjected to external pressure, generating friction to achieve the purpose of decelerating the vehicle.

[0003] The brake pad is composed of a friction substrate and a brake pad steel back. Glue is often used to install the friction substrate and the brake pad steel back. The friction substrate and the brake pad steel back installed with glue need to be further crimped on a press. However, in the existing technology, corresponding protruding structures are usually provided at both ends of the brake pad steel back. When the brake pad steel back is directly taken to the press for crimping, the press will first contact and apply pressure to the protruding parts at both ends of the brake pad steel back, which will then crush or break the protruding parts at both ends of the brake pad steel back, causing the brake pad steel back to be scrapped.

[0004] Therefore, it is particularly important to design a brake pad forming and positioning tool to solve the above-mentioned defects. Utility Model Content
