Problems solved by technology

Utilizing this process to prepare disc brake pads has the following disadvantages: the filling process in this process is to directly fill the mixture of powdery lining into the mold and heat it to bond with the steel back. The uneven heat transfer and large temperature gradient of the mixture will make the powdery mixture unable to obtain uniform chemical reaction and uniform change of physical shape, resulting in uneven distribution of thermal stress in the internal structure of the prepared brake pad, and the prepared br...

Abstract

The invention relates to a preparing method and special device of disc brake block, belonging to the brake block technique. The inventive method comprises: preparing steel back; preparing liner material; cold compressing molding; heat compressing solidifying and hot treatment. The invention adds cold compressing molding of brake block, therefore, the brake block has uniform hot stress distribution to avoid the defects of expansion and chap, with lower cost and high producing efficiency.

Description

technical field [0001] The invention belongs to the technical field of brake pad preparation, and specifically discloses a preparation process and special equipment for a disc brake pad. Background technique [0002] At present, there are two processes for the preparation of disc brake pads. A kind of technology—as the patent No. is 96115295.8, the announcement number is CN1165255, and the name is the technology disclosed by the invention patent of a kind of brake pad. The preparation process of the brake pads is: the cutting of the steel back, the kneading of the brake pad lining, the pretreatment of raw materials including drying and crushing, the application of release agent to the preheated mold, and the addition of steel coated with adhesive. After backing and pre-processing the lining material, it is heated and pressed once for hot pressing and other processes. Utilizing this process to prepare disc brake pads has the following disadvantages: t...
