Brake Pad Cold Press Manufacturing Process

Abstract

The invention discloses a cold pressing manufacturing process of a brake block. The process is characterized by comprising the steps of 1, preparing a steel back; 2, preparing a gasket material; 3, performing cold pressing and forming for the brake block; 4, shaping and brake block; 5, thermally processing the brake block. Compared with the traditional cold-pressed brake block, the cold-pressed brake block manufactured by the process has the advantages of being high in surface porosity factor, high in high-temperature declining performance, high in shearing resistance, stable in quality, and long in service life.

Description

technical field

[0001] The invention relates to a manufacturing process of brake pads for motor vehicles and non-motor vehicles. Background technique

[0002] In order to ensure driving safety, no matter motor vehicle or some non-motor vehicles all have brake components with brake pads. An ideal brake pad should have low braking sound when performing braking work (related to the porosity of the brake pad, especially the surface porosity, the greater the surface porosity, the smaller the braking sound, and vice versa), good high temperature decay performance, and shear resistance. Strong cutting force, stable quality, long service life and other excellent comprehensive performance. At present, there are brake pads made by cold-pressing technology on the market, such as the method provided by patent No. 201110457229.4 and patent name "Cold-pressing One-time Forming Method of Disc Brake Pad", but the cold-pressed brake pads made by the above-mentioned patented method There ar...
