Novel brake pad and mold and method for preparing brake pad

Abstract

A novel brake pad and a mold and method for preparing the brake pad. The invention proposes a new type of brake pad, which includes a friction material block, and the friction working surface of the friction material block is formed with a plurality of stepped working surfaces with different heights and gradually raised or lowered. In this way, the step-by-step working surface of the present invention forms a step-shaped chamfer, which can effectively reduce brake noise and efficiently remove wear debris, and as the The consumption of the friction material block increases the friction area with the tire brake disc step by step, so that the braking effect will not be poor due to the smooth friction surface after long-term use. Therefore, the braking noise of the present invention is low, the chip removal effect is good, the friction effect is good, stable and durable, and has strong practicability. The invention also provides a mold, which can integrally form the brake pad, has no bad demoulding, high efficiency, strong bonding force, stable quality, low cost, material saving and no industrial waste. The invention also proposes a method with clear and concise steps, which can efficiently prepare integrally formed brake pads.

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.
