Abstract
The invention discloses a machining process for a bimetal bush. The machining process is characterized by comprising the steps of blanking, oil groove punching, hasp punching, pre-bending, large-bending, rounding, extrusion, end face turning, integration and test packaging completing. The machining process has the beneficial effects that the bimetal bush machined through the machining process is high in precision and long in service life, the work efficiency is improved by one time compared with the original work efficiency, and the rejection rate is lowered.
Description
Technical field
The present invention relates to the processing technique of a kind of lining, especially relate to the processing technique of a kind of bimetal liner。
Background technology
At present, along with the development of modern industry, roll bimetal liner and get more and more in the application of machinery industry, but in its course of processing, there is operation more, the factors such as product shaping prescription is high, to manpower, equipment, frock input also bigger。This adds the processing cost of axle sleeve undoubtedly, is unfavorable for the tremendous development of enterprise。And produced bimetal liner precision is high, service life is not long。
Summary of the invention
It is an object of the invention to provide the processing technique of a kind of bimetal liner, solve the problem that the existing bimetal liner accuracy of manufacture is high, service life is not grown。
The technical solution adopted for the present invention to solve the technical problems is: the processing technique of a kind of bimetal liner, it is characterized in that: including: blanking, pressure oil groove, rush hasp, pre-bending, curved greatly, full circle, extruding, face work, integration, test package complete, and are specially step；
(1), blanking: steel plate and copper coin cut into specific length and width according to product requirement；
(2), pressure oil groove: go out the oil groove designing size at steel plate and copper coin；
(3), rush hasp: the edge at steel plate and copper coin sets goes out edge hasp, and is combined by the sheet material of bi-material, adopt spot welding riveted or pressure to be pressed into alloy components；
(4), pre-bending: on the pressure of the pre-bend mould coordinated, alloy components is placed on the camber suppressing alloy components two ends on mould；
(5), bend: coordinate bending die to be combined at the alloy components two ends of bending two ends；
(6), full circle: with conductivity type post by alloy components shaping；
(7), extruding: side and compression mould with coupling alloy components profile radius carry out the final shaping while shaping；
(8), integrate: the two of alloy components end faces are got on the bus flat at grinding machine, and in the oral area chamfering at two ends, finally by the outside fine grinding of alloy components。
Beneficial effects of the present invention: the precision of the bimetal liner that use the method processes is high, long service life, and work efficiency was doubled than originally, reduces and scraps。
Detailed description of the invention
Embodiment, the processing technique of a kind of bimetal liner, it is characterised in that: including: blanking, pressure oil groove, rush hasp, pre-bending, curved greatly, full circle, extruding, face work, integration, test package complete, and are specially step；
(1), blanking: steel plate and copper coin cut into specific length and width according to product requirement；The length of the metallic plate that its outside metallic plate arranged is arranged than inside is wide 0.5-0.8 centimetre, and two kinds of metallic plates are carried out degreasing process, and middle plate carries out pickling, Passivation Treatment, removes the rust on surface；Steel plate thickness rolls regulation requirement, and thickness deviation controls at ± 0.01mm, higher than of the same trade ± 0.02mm level；
Enter back into sintering step, front with special scraping or screen cloth, copper powder is laid on surface of steel plate uniformly, select QSn6Zn6Pb3 tin bronze powder, control the proportioning of copper powder particle size, density 4.1g/cm3After copper powder is completed, put in high temperature net belt type sintering furnace and sinter, make between metallic particles, local sintering between granule and steel plate and copper coin, formed stephanoporate framework, sintering temperature is 890-910 DEG C, push away boat speed 700-750r/min, sintering time is 45～60min, and sheet material, by also being lowered the temperature by the coolant jacket of certain length behind sintering zone, is come out of the stove to less than 100 DEG C；
(2), pressure oil groove: go out the oil groove designing size at steel plate and copper coin；
(3), rush hasp: the edge at steel plate and copper coin sets goes out edge hasp, and is combined by the sheet material of bi-material, adopt spot welding riveted or pressure to be pressed into alloy components；
(4), pre-bending: on the pressure of the pre-bend mould coordinated, alloy components is placed on the camber suppressing alloy components two ends on mould；
(5), bend: coordinate bending die to be combined at the alloy components two ends of bending two ends；
(6), full circle: with conductivity type post by alloy components shaping；
(7), extruding: side and compression mould with coupling alloy components profile radius carry out the final shaping while shaping；
(8), integrate: the two of alloy components end faces are got on the bus flat at grinding machine, and in the oral area chamfering at two ends, finally by the outside fine grinding of alloy components。
Above embodiments is only that the preferred embodiment of the present invention is described; not the scope of the present invention is defined; under the premise designing spirit without departing from the present invention; various deformation that technical scheme is made by this area ordinary skill technical staff and improvement, all should fall in the protection domain that claims of the present invention are determined。
Part that the present invention does not relate to is all same as the prior art maybe can adopt prior art to be realized。
