Abstract
The present invention discloses a hot forming method on the surface of a composite material component. The present invention aims to provide a hot forming method on the surface of a composite material component, which has the advantages of simple manufacturing process, high processing precision, favorable roughness and low manufacturing cost. The method of the present invention comprises: firstly, the shape of base material is processed according to component requirements; secondly, copper powder is sintered on the friction surface of a component; finally, non-metallic material friction reducing particles are laid on the friction surface and are sintered in a mold which is heated or in a heated hot mold under the pressurizing condition. The method has great application value for the manufacture of composite material components with large and non-uniform material thickness.
Description
Technical field
The present invention relates to a kind of part forming method, relate in particular to a kind of laminated composite material part forming method with steel-copper-nonmetallic materials.
Background technology
Metal material, macromolecular material and ceramic material respectively possess some good points on serviceability and are not enough, and the range of application of oneself is respectively arranged.Along with science and technology development, more and more higher to the requirement of material, use single material to satisfy these requirements and become more and more difficult.Therefore, composite has appearred, at present, the general laminated composite material of Shi Yonging, as the oil-free lubrication sliding bearing of steel-copper-nonmetallic materials, these sliding bearings generally are axle sleeve class shapes.Its technology is: cutting steel plate-surface of steel plate shop copper powder sintering-smoothing-surface is spread nonmetallic materials anti-attrition particles sintering-smoothing and is rolled onto specific thickness and becomes blank-put in storage according to sliding bearing size blanking-circle circle-shaping-check.This flat sheet of making composite earlier reshapes method for processing and only is fit to the uniform part of thickness, because the inconsistency of material physical property, as the thermal expansion factor difference, when high temperature, separates between the easily wrinkling or material faying face; In the BENDING PROCESS after material becomes flat board, because the curvature difference of material ectonexine also can cause the separation between the material faying face, in addition, because in the shaping process, slidingsurface scratches easily, and the precision of processing and coarse also being difficult to guarantee, influence the quality of part.And for material thickness part big, in uneven thickness, be the plane as lower surface, upper surface is that rubbing surface is that the manufacturing of arcuate part just seems very difficult.
Summary of the invention
The object of the present invention is to provide that a kind of technology is simple, machining accuracy is high and the thermo shaping method of the composite material component port surface of coarse good, low cost of manufacture.
In order to achieve the above object, a kind of technical scheme of thermo shaping method of composite material component port surface is: comprise at first that according to part it is the shape of base material that requirement processes with the steel; Secondly at the friction surface sintered copper powder; Spread nonmetallic materials anti-attrition particles sintering at friction surface again, it is characterized in that at the sintering of spreading nonmetallic materials anti-attrition particle it being to finish under the condition of in mould, pressurizeing in heating or heating back the mould in heat.Described pressurization is meant and keeps the just demoulding after 1 minute after part pressurizes at least in mould.
Method according to the above-mentioned back sintering that is shaped earlier comes the formed composite material piece surface has the following advantages:
1, technology is simple.It has overcome traditional handicraft with the bending forming forming effect that is beyond one's reach.
2, machining accuracy and coarse good.Requirement on machining accuracy to the blank part is not high, guarantees surperficial machining accuracy and roughness by mould, and is good to producing interchangeablity in batches especially.
3, low cost of manufacture.Can remove complicated machining and multiple tracks trimming from, the production efficiency height.

The specific embodiment
With the example that is processed as of part slideway, the invention will be further described in conjunction with the accompanying drawings below.
As shown in Figure 1 and Figure 2, it is to be used in slideway 1 parts pattern that the gate two sides are used to lead, and upper surface 2 is anti-attrition surfaces of arch, is coated with composite.Its processing method:
Require to process shape such as Fig. 3 that steel is a base material 3 according to slideway 1 part; Secondly at friction surface sintered, spherical copper powder 4 as Fig. 4; Nonmetallic materials anti-attrition particle 5 is spread on the surface of copper powder in the cooling back, part is put into baking oven heat, and is warming up to 250 ℃ of heat penetrations.
In addition, make corresponding patrix 6 and counterdie 7 according to the shape of upper surface 2, patrix 6 and counterdie 7 are heated between 230 ℃-280 ℃, slideway 1 blank after putting into heating in the middle of patrix 6 and the counterdie 7, the processing of slideway 1 part is promptly finished in matched moulds pressurization molding after 3 minutes after the demoulding.
The temperature that above-mentioned part heats in baking oven can be selected between 200 ℃-300 ℃, as 220 ℃, 240 ℃, 250 ℃, 260 ℃, 270 ℃ etc.
The mold temperature of above-mentioned heat can be between 200 ℃-300 ℃, as 220 ℃, 240 ℃, 250 ℃, 260 ℃, 270 ℃ etc.
Can in the mould of heat, directly pressurize for little part and to finish processing, needn't preheating.
