Abstract
The present invention relates to automobile brake, and is especially the production process of piston material for brake in automobile. The piston material is produced with modified wollastonite fiber as main material and phenolic resin as supplementary material and through mixing in certain ratio, stoving, hot pressing to mold and mechanical forming. The piston of composite material has light weight, less hot deformation, low cost, high performance, simple production process and environment friendship.
Description
Technical field
The present invention relates to automotive brake, specifically, relate to the material of brake plunger.
Background technique
Along with fast development of national economy, the automobile industry of China has also had significant progress.Each manufacturer of automobile industry is in order to occupy advantage in competition, and except releasing designs and varieties miscellaneous, prior is exactly the quality that improves auto parts and components by fair means or foul, reduces production costs, and helps environmental protection.Piston is crucial component in the automotive brake, and the quality of break quality is directly connected to the safety of automobilism, so the production of piston receives much concern.Be born to present last 100 years from automobile, piston all adopts the high-quality steel to carry out machining as material, carries out chromium plating after processing again and handles, and its cost is higher, and chrome-plated process befouling environment also.
Summary of the invention
Purpose of the present invention just is to adopt a kind of new nonmetallic composite piston substituted metal piston, specifically just provides a kind of production method of car brake composite material piston.
The object of the present invention is achieved like this: with the modified silicon ash mineral wool is raw material, is auxiliary material with phenolic resin, mixes oven dry according to a certain percentage, utilizes the mould heat pressure base, is shaped through machining again.
The present invention has following advantage and good effect:
1. composite material piston has in light weightly, and its density is about 1/4th of metallic piston; Thermal distortion is little, in the using scope of piston, is about the sixth of metallic piston; Cost is low, and for the piston of same model, its cost of production is about 1/2nd of metallic piston; Performance is good, and when being used for the disk type braker piston, the return performance is better than metallic piston.
2. production technology is simple, is easy to grasp.
3. the feature of environmental protection is good, non-environmental-pollution during production; And metallic piston needs hard chromium plating, and environmental pollution is serious.
In a word, the present invention is a kind of production method that existing metallic piston is updated, and its market prospects are boundless.
Description of drawings
Fig. 1 is a flow chart of the present invention;
Fig. 2 is a die structure dwg of the present invention.Wherein:
1-raw material, the modified silicon ash mineral wool is pressed 76-78%;
2-auxiliary material, phenolic resin is pressed 22-24%;
Material screening machine is adopted in 3-screening;
4-mix, adopt batch mixer;
5-oven dry, 50 ℃;
6-dress mould;
7-mould, 7.1-upper die tooling, 7.2-upward heating plates, 7.3-bed die, 7.4-following heating plate;
8-heating, 165-175 ℃;

12-machining is processed into finished product with blank by figure, mainly is cylindrical grinding;
13-check warehouse-in;
14-piston.
As shown in Figure 1, flow process of the present invention is: raw material 1 → screening 2 → mixing 4, auxiliary material → mixing 4; Mix 4 → oven dry 5 → dress mould 6 → mould 7, heating 8 → mould 7, compacting 9 → mould 7; Mould 7 → depanning 10 → check 11 → machining 12 → check warehouse-in 13.
As shown in Figure 2, the structure of mould 7 of the present invention is made up of upper die tooling 7.1, last heating plate 7.2, bed die 7.3, following heating plate 7.4.
Embodiment
1. select materials by a certain percentage and mix oven dry
Choosing the modified silicon ash mineral wool is raw material 1, the row filter 3 of going forward side by side; Choosing phenolic resin again is auxiliary material 2; Raw material is pressed 76-78%, and auxiliary material is pressed 22-24%, pours in the batch mixer and mixes 4, dries 5 again, and bake out temperature is 50 ℃.
2. utilize mould heat pressure to make blank
Between the upper die tooling 7.1 and bed die 7.3 of mixture dress mould 6 in mould 7 with oven dry, to the last heating plate 7.2 and 7.4 heating 8 of following heating plate of mould 7, heating-up temperature is 165-175 ℃, suppresses the blank depanning 10 that can make piston 14 after 9 more again.
3. be shaped through machining
The blank of piston 14 is machining 12 again after checking 11, mainly is cylindrical grinding, and the check warehouse-in 13 at last.
