Abstract
The invention provides a production method of an automotive brake pad. The production method comprises the following steps: material mixing: 10 parts of phenolic resin, 4 parts of glass fibers, 2 parts of copper fibers, 2 parts of butyronitrile rubber powder, 3 parts of a grinding agent, 10 parts of graphite, 15 parts of barite, 3 parts of antimony sulfide, 1 part of steel fibers, 2 parts of molybdenum disulfide, 3 parts of pyrophyllite, 1 part of barium sulfate, 4 parts of composite cotton and 5 parts of bamboo fibers are mixed, dried materials are put into a reserving mold, friction materials are pressed by a press, and a reserve is prepared; heat treatment forming: the reserve is subjected to heat treatment at 170 DEG C for 1.5 h, and then the brake pad is prepared and cooled with the furnace; finishing: flash and burrs around the brake pad subjected to heat treatment are treated with a cutter, drilling is performed, and inside arc, outside arc and chamfer are ground. A friction work layer is a highly wear-resistant layer and made of a material with higher cost but excellent wear resistance, the cost is low, and the production process is simple and convenient.
Description
Technical field
The invention belongs to automobile part production technique field, more particularly to a kind of making side of automobile brake sheet
Method.
Background technology
With the progress of society, the use of automobile extensive, the requisite traffic work into life all the more
Tool, consumption of the people to automobile is also more and more, and the demand of auto parts machinery is also increasing.
Automobile brake brake block is the critical function part for controlling and ensureing vehicle safety travel, the operation principle of brake
It is mainly and carrys out self-friction, using the friction on brake block and brake disc (drum) and tire and ground, by vehicle row
The kinetic energy for entering is converted into the heat energy after rubbing, and car is stopped.A set of good efficient brake system must
Stable, enough, controllable brake weight must can be provided, and with good hydraulic pressure transfer and heat-sinking capability,
To guarantee that driver sufficiently effective can pass to master cylinder and each wheel cylinder from the power that brake pedal is applied, and avoid height
Hydraulic failure and brake decline caused by hot institute.
Brake block is extremely great for traffic safety is acted on, and brake in the market mostly is metal, is fabricated to
This height, transmission hot property is big, and manufacture craft is loaded down with trivial details, and for wearing no resistance, shock resistance is poor, noise is larger,
Therefore, a kind of new brake block is badly in need of on market.
The content of the invention
The technical problem to be solved in the present invention is, for the deficiencies in the prior art, to propose a kind of automobile brake sheet
Preparation method.
The technical problem to be solved in the present invention is achieved through the following technical solutions, a kind of automobile brake sheet
Preparation method, is characterized in, comprises the following steps：
