Abstract
The invention discloses a method for manufacturing an automobile brake pad. The method includes the following steps of (a) material mixture, (b) pre-forming, (c), thermal forming, (d) thermal treatment and (e) grinding, wherein a friction material part of the brake pad is removed through a grinding machine, so that the set thickness is reached. A friction material is firstly preformed by a press after being mixed, the state of the friction material is changed into paste from powder, and the initial performance is achieved; then, a prepared product and a back plate are pressed through a thermal forming machine at high temperature and high pressure, so that the performance of the brake pad is improved. The brake pad is good in abrasion resistance and braking performance.
Description
Technical field
The present invention relates to the preparation method of brake pad of car.
Background technique
Automobile brake brake block is the critical function part controlling and ensure vehicle safety travel.In recent years, the development of highway, railway traffic accelerates the process of the Transport Machinery such as automobile, train high-speed overload, thus has higher requirement to the performance of friction plate in braking device.The lifting of Vehicle Speed requires that friction plate can have stable frictional behaviour in wider speed, temperature range.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of brake flat manufacturing technique of good performance.
The solution that the present invention solves its technical problem is: a kind of manufacture method of automobile brake sheet, comprises the steps: a) batch mixing: mixed in proportion by following material: phenol-formaldehyde resin modified, Steel Fibre, bastose, carbon fiber, red copper fiber, molybdenum disulfide, zinc powder, graphite, pyrophillite, barium sulphate; B) prepare shaping: pour the friction material completing batch mixing in step a into preparation shaping die, then utilize press machine that friction material is suppressed reserve; C) thermoforming: mould reserve and base plate being put into thermal shaping machine, utilizes together with reserve suppresses with base plate by High Temperature High Pressure, forms brake block; D) heat treatment: brake block is dropped in heat treatment furnace, in-furnace temperature being risen to 150 ~ 250 DEG C of times of carrying out is the heat treatment of 6 ~ 10H; E) grinding: get rid of, to reach setting thickness by the friction material part of lapping machine by brake block.
As the further improvement of technique scheme, the preparation briquetting pressure in described step b is 3 ~ 10Mpa, and temperature is 15 ~ 40 DEG C; Dwell time is: 6 ~ 30 seconds.
As the further improvement of technique scheme, the thermoforming pressure in described step c is 150 ~ 300Mpa; Temperature is 140 ~ 200 DEG C; Dwell time is: 180 ~ 400 seconds.
The invention has the beneficial effects as follows: friction material, after batch mixing, is first carried out preparation shaping, made friction material transfer paste to by powdery, have preliminary performance under press machine; Then reserve and backboard are suppressed through thermal shaping machine High Temperature High Pressure and form, improve the performance of brake block.Brake block of the present invention is wear-resisting, braking ability good.
