Description

A kind of bearing parts carbon fiber forming technique and mould thereof
Technical field
The present invention relates to a kind of carbon fiber component moulding process, particularly relate to a kind of bearing parts carbon fiber forming technique and Its mould.
Background technology
Carbon fiber forming is mainly realized by following three kinds of methods: winding method, lamellar die pressing and paperhanging method.These three side Method production efficiency is low, and cost is high, is not suitable for producing in enormous quantities.The serious popularization and application restricting new material.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, it is provided that a kind of bearing parts carbon fiber forming technique, Solve in prior art the problem that carbon fiber forming efficiency is low, cost is high.
Another object of the present invention is to provide a kind of bearing parts carbon fiber forming mould.
One bearing parts carbon fiber forming technique of the present invention comprises the steps:
Carbon fiber to be prepared premix bulk material before pressing component, weight of drawing materials, more than 5% the 10% of part weight, treats mould temperature Degree reaches 1350C-1750After C, opening hydraulic press and opened by mould, load weighted bulk material is put into die cavity, hydraulic press closes The compacting pressurize molding of rear mold matched moulds, 5-10 minute dwell time, briquetting pressure 10Mpa.Bulk material is in heat and the effect of pressure Lower melt-flow is full of whole die cavity, resin and firming agent effect and crosslinks reaction, generates insoluble build compound, bulk Material thus solidification, become tool effigurate goods, when goods are shaped completely, hydraulic press open open mould, eject system Part, completes carbon fiber product manufacturing process.
The cumulative volume of described die cavity material room is greater than the cumulative volume 20% 50% of rolled-up stock.
A kind of bearing parts carbon fiber forming mould structure is as follows:
The bottom of round core is arranged on mounting base, and the top of round core connects core, and being provided above of core installs top board, installs The lower section of top board sets gradually fixed plate, template and backing plate, is provided with gripper shoe between two ends and the mounting base of backing plate, backing plate, Form cavity, push pedal and dress pin plate between gripper shoe and mounting base to be successively set on the mounting base in cavity, round core Outer surface suit ejector sleeve, the two ends of ejector sleeve offset with core and mounting base respectively.
Advantages of the present invention effect is as follows:
Using the compressing production in enormous quantities realizing Carbon fibe goods of mould, workpiece can be hidden sufficient coherence request from, be processed into This is low, and efficiency is high, and quality is good.Complex part molding can be realized.
Accompanying drawing explanation
Fig. 1 inventive die structural representation.
In figure, 1, top board is installed, 2, fixed plate, 3, template, 4, backing plate, 5, gripper shoe, 6, mounting base, 7, push pedal, 8, Dress pin plate, 9, round core, 10, ejector sleeve, 11, core.
Detailed description of the invention
The present invention is as a example by Underwater pump bearing part produces, and the process of its carbon fiber forming comprises the steps:
Immersible pump carbon fiber bearing compression molding is designed as mould 8 chamber, and every chamber independently expects that room, the cumulative volume of single-chamber material room are greater than The cumulative volume of rolled-up stock about 20% 50%.Carbon fiber to be prepared premix bulk material before pressing component, weight of drawing materials is more than product 5% the 10% of weight, treat that mold temperature reaches 1350C-1750After C, open hydraulic press and mould is opened, load weighted bulk Die cavity put into by material, hydraulic press Guan Bi rear mold matched moulds compacting pressurize molding, 5-10 minute dwell time, briquetting pressure 10Mpa, Bulk material melt-flow under the action of heat and pressure is full of whole die cavity,
Bisphenol A epoxide resin E44 forms dough after uniformly mixing with carbon fiber wire, crosslinks reaction, (mould after molding Reach moulding process temperature) generate insoluble build compound, bulk material thus solidification, become tool effigurate goods, When goods are shaped completely, hydraulic press is opened and is opened mould, ejects product, completes carbon fiber product manufacturing process.
A kind of bearing parts carbon fiber forming mould structure is as follows:
The bottom of round core 9 is arranged on mounting base 6, and the top of round core 9 connects core 11, and the installation that is provided above of core 11 is pushed up Plate 1, the lower section installing top board 1 sets gradually fixed plate 2, template 3 and backing plate 3, sets between two ends and the mounting base 6 of backing plate 3 There is gripper shoe 5, form cavity, push pedal 7 and dress pin plate 8 between backing plate 4, gripper shoe 5 and mounting base 6 and be successively set in cavity Mounting base 6 on, the outer surface of round core 9 suit ejector sleeve 10, the two ends of ejector sleeve 10 respectively with core 11 and mounting base 6 phase Support.
Inventive die use electrothermal tube heating, temperature automatically controlled with thermocouple, it is ensured that mould at a temperature of technological requirement just Often work.Product takes out and uses sleeve pipe pushing method, ejects workpiece deformation little, and inherent quality ensure that.
Mold cavity and core material, select its trade mark of preferable mould steel be 4Cr5MoSiV1, this material have heat-resisting, Wear-resistant, corrosion-resistant, there is good heat stability, at a temperature of mold work, mould can keep the advantage such as indeformable.Generally quench Fire hardness is HRC52-55, and this part processing technique is to carry out Quenching Treatment after first roughing to carry out polish again, it is ensured that die cavity, Core is indeformable after processing.Fixed plate and template use CrWMn mould steel to improve intensity and the abrasion resistance of mould faying face, and it is quenched Fire hardness is HRC50-52.
Compression molding is one of thermoset plastic forming method, can add a certain proportion of reinforcing material in matrix material As glass fibre, chopped carbon fiber, chopped aramid fiber etc. can process the composite product of high-quality, high intensity；This The protection domain of invention is as the criterion with claims, is not limited by specific embodiment institute.
