Problems solved by technology

[0002] Most of the existing brake pads are made of composite fiber, graphite, resin, nitrile rubber, glass fiber and asbestos. Now, because asbestos is harmful to the human body, it is prohibited to use it; therefore, companies are now looking for substitutes for asbestos. After using other fibers, it is found that it is very difficult to form according to the original process during preforming, and the preformed semi-finished products are fragile

Embodiment Construction

[0016] Such as figure 1 A brake pad preforming process of the present invention is shown, comprising the following steps:

[0017] Step 1. Weigh the mixed material after stirring, and put it into a film bag. The film bag is a polypropylene film bag, and the thickness of the film bag is 3 to 5 wires, so that the film bag Easy to melt and adhere to the surface of preformed brake pads;

[0018] Step 2. Put the film bag containing the mixture into the hydraulic press, press 20mPa, temperature 50 to 70°C, hold the pressure for a set time, and cycle the pressing for a set number of times. The set time is 2 to 4 seconds. The above setting times are 3 times;

[0019] Step 3. After the pressing is completed, the mold is ejected to obtain a preformed brake pad.

[0020] The above preformed brake pads are subjected to curing heat treatment according to the existing process. During the curing heat treatment, the film bag on the surface of the preformed brake pads can be burned, and the...

Abstract

The invention provides a brake pad preforming process which comprises the following steps: step 1, weighing a stirred and mixed mixture, and loading the weighed mixture into a film bag; step 2, carrying out hot press molding on the film bag filled with the mixture; 3, after pressing is completed, drawing is conducted, and a preformed brake pad is obtained; therefore, the preformed brake pad is easy to form and not easy to break.

Description

technical field [0001] The invention relates to a brake pad preforming process. Background technique [0002] Most of the existing brake pads are made of composite fiber, graphite, resin, nitrile rubber, glass fiber and asbestos. Now, because asbestos is harmful to the human body, it is prohibited to use it; therefore, companies are now looking for substitutes for asbestos. After using other fibers, it is found that according to the original process, it is very difficult to form during preforming, and the preformed semi-finished product is fragile. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a brake pad preforming process, so that the preformed brake pad is easy to form and not fragile. [0004] The present invention is achieved in that a brake pad preforming process comprises the following steps: [0005] Step 1. Weigh the mixture that has been stirred and mixed, and put it into a film bag; [0006] Step ...
