A kind of production method and forming equipment of brake shoe

Abstract

The invention discloses a production method of a brake rubber block as well as a forming device. The production method comprises the following steps: uniformly mixing and stirring the following materials: 13-15 parts of rock wool, 4-6 parts of barite powder, 5-7 parts of resin powder, 1-2 parts of vermiculite powder, 1-2 parts of feldspar powder, 1-2 parts of tyre powder, 0.2-0.3 part of zinc stearate and 0.8-1.2 parts of frictional powder; arranging a brake framework, and brushing glue on a concave arc surface which is required to be covered with the brake rubber block; pushing the arranged brake framework below a discharge mold groove, weighing 30-40g of mixed material and pouring the material into the discharge mold groove so as to enable the mixed material to be contained in the concave arc surface of the brake rubber block; and pushing the discharge mold groove and the brake framework together into a mold press and performing extrusion forming for 3-5 minutes at the pressure of 18-22PA under the condition that the temperature of a pressing die compartment is controlled to be 170-190 degrees. The production method of the brake rubber block as well as the forming device have the following advantages that the forming efficiency is high, and the forming cost is reduced; less mixed material is used compared with that of the prior art; on the aspect of the finished product quality, the brake rubber block and the brake framework which are produced by the technology provided by the invention are more firm.

Description

technical field [0001] The invention relates to a production method and molding equipment for brake pads. Background technique [0002] In the existing production method of brake pads, firstly, the brake pads are formed; then, after forming, the two sides thereof are chamfered, preferably, the brake pads and the frame are glued by brushing. It has the following disadvantages: first, the forming steps are cumbersome, the forming efficiency is low, and the cost is high; second, the bonding firmness between the brake shoe and the frame is poor, and there is a possibility of falling off. Contents of the invention [0003] The invention provides a brake pad production method and molding equipment, which overcome the shortcomings of the brake pad production method in the background art. [0004] One of the adopted technical schemes that the present invention solves its technical problem is: [0005] A method for producing brake pads, comprising: [0006] (1), mixing step, mix...
