Novel brake pad and mold and method for manufacturing same

Abstract

The invention provides a novel brake pad and mold and method for manufacturing the novel brake pad. The novel brake pad includes a friction material block. A plurality of stepped working surfaces which have different heights and rise or fall step by step are formed on the friction working surface of the friction material block. In this way, the stepped working surfaces rising or falling step by step form chamfers in a step form. According to the chamfers in the step form, abraded scraps can be removed efficiently while braking noise is lowered effectively; in addition, with consumption of the friction material block during use, the friction area of the friction material block with a tire braking disc increases step by step, and therefore the situation that as friction surfaces become smooth after a long time of use, the braking effect is poor is avoided. Accordingly, the novel bake pad is low in braking noise, good in scrap removal effect and friction effect, stable, durable and high in practicability. The invention further provides a mold, and the mold enables the brake pad to be integrally formed, avoids bad stripping and is high in efficiency and cementing force, stable in quality, low in cost, capable of saving materials and free of industrial waste. The invention further provides the method, steps are clear and concise, and therefore the integrated formed brake pad can be manufactured efficiently.

Description

technical field [0001] The invention relates to the field of a brake pad and its preparation device and method, in particular to a novel brake pad, a mold and a method for preparing the brake pad. Background technique [0002] Disc brake pads used in rail vehicles, automobiles, motorcycles, and other industrial machinery and agricultural machinery are generally composed of linings (usually steel plates), adhesive layers, and friction materials. The aforementioned friction materials are made of reinforcing fibers, organic materials, friction The adjustment material is constructed and fixed to the liner by adhesive. The solvent-based adhesive of heat-reactive resin is sprayed or coated on the lining and then dried, or an adhesive film is sandwiched between the lining and the friction material block, and the friction material is fixed on the lining by heating and pressing. Specifically, as disclosed in Chinese invention patent CN201210124096.3, a method for manufacturing an au...

Problems solved by technology

[0004] However, the braking noise of the brake pads and the effect of removing wear debris need to be improved at present, and the brake pads prepared according to the aforementioned brake pad manufacturing method, according to the requirements of reducing brake noise, removing wear debris, strength and performance, are also improved. Subsequent processing such as chamfering, ditching and deburring of the thermoformed brake pad friction material block needs to be performed with cutters, grinders, etc.

In this way, in the process of timing processing and use, there will be cumbersome procedures, low efficiency, insufficient cementing force, unstable quality, high cost, serious waste of materials and a lot of industrial fertilizer waste.
