Abstract
The present invention relates to a kind of electric railway and public transport contact line contact wire copper-aluminum composite contact wire.Its special character is: is a whole wire rod with copper or copper alloy and aluminium or aluminium alloy bimetallic by the plastic deformation composite molding, and making is aluminium or aluminium alloy with aluminium clip contact site wherein, and with locomotive pantograph contact site be copper alloy.The comprehensive conductance of copper-aluminum composite contact wire is 65%IACS～105%IACS; The hardness of its working position copper or the copper alloy of pantograph sliding friction (promptly with) is HB90～200; The copper-aluminum composite contact wire copper aluminium engaging force that the technology of the present invention is produced is 400～550N/cm.
Description
Technical field
The present invention relates to a kind of electric railway and public transport contact line contact wire copper-aluminum composite contact wire.
Background technology
Contact wire is a kind of lead for electric power locomotive bow collector transmission current.The domestic contact wire that is applied to electric railway and public transit system mostly is copper or copper alloy contact wire at present, because the electrical wiring clip uses the aluminum or aluminum alloy folder more, therefore when practical application, forming with copper easily is negative electrode, aluminium is anode, and rainwater, condensation etc. are the electrolyte electrochemical corrosion, has a strong impact on the life-span of aluminum binding clip, and shortened electric railway and repaiied the cycle of changing, very be unfavorable for the normal operation of electric railway and public transport.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of conductance height, resistance to wear good, fully avoid the electrochemical corrosion of aluminium clip, improve the copper-aluminum composite contact wire in binding clip life-span.
The technical solution adopted for the present invention to solve the technical problems is: a kind of copper-aluminum composite contact wire, its special character is: is a whole wire rod with copper or copper alloy and aluminium or aluminium alloy bimetallic by the plastic deformation composite molding, making is aluminium or aluminium alloy with aluminium clip contact site wherein, and with locomotive pantograph contact site be copper or copper alloy.
According to above-mentioned a kind of copper-aluminum composite contact wire, technical scheme is "---compound in advance---drawing and setting of copper cash base, aluminum steel base ", or the process route of " copper cash base, aluminum steel base---stretching ".All the needing at last of all technical schemes aligns.
The design of the technology of the present invention and the foundation of realization are as follows:
Plastic working has that deformation force is big, the accurate characteristics of processing dimension, utilizes special processing technology to make copper or copper alloy and aluminum or aluminum alloy produce same step plastic deformation, keeps the continuity on the length direction; And two kinds of metals are embedded in deformation process mutually, reach fine and close, high-intensity combination.
The copper blank carries out predeformation, can make copper just possess enough hardness before compound with aluminium, to guarantee the hardness requirement of final products to the copper part.
This procedure that stretches of all will adopt in all invention schemes, but the size and the surface quality of the finishing product that stretches can accurately be controlled the overall dimension of product, and product surface is bright and clean, the product warpage, turns round and twists phenomenon and alleviate.
To adopt the aligning operation at last in the invention scheme, aligning will solve product bending, warpage, turn round defectives such as stubborn, make product have fabulous glacing flatness.
The invention has the beneficial effects as follows: the comprehensive conductance of the copper-aluminum composite contact wire of being produced is 65%IACS～85%IACS, can reach various conductance requirements by changing the copper aluminium sectional area ratio and the conversion copper alloy trade mark and the aluminium alloy trade mark; The hardness of the working position of the copper-aluminum composite contact wire of the being produced copper alloy part of pantograph sliding friction (promptly with) is HB90～200, can and carry out special thermal treatment by the conversion copper alloy trade mark, conversion working modulus and obtain needed hardness requirement; The copper-aluminum composite contact wire copper aluminium engaging force that the technology of the present invention is produced is 400～550N/cm.
Embodiment
The invention will be further described below in conjunction with embodiment:
Embodiment one: adopt yellow gold line base, 6063 aluminium alloy wire bases, the pre-compound working procedure that stretches is handled, and carries out the technology that the drawing and setting operation is handled again.Earlier by continuously extruded yellow gold line base and the 6063 aluminium alloy wire bases of making, again yellow gold line base is carried out ε=55% tensile pre-deformation, on 5 tons of broaching machines, carry out compoundly in advance by drawing die, on same broaching machine, carry out sizing immediately and stretch compoundly, carry out stretcher leveling at last.
Embodiment two: by "---the continuously extruded compound in advance---drawing and setting of copper cash base, aluminum steel base " of the present invention operation, earlier by continuously extruded yellow gold line base and the 6063 aluminium alloy wire bases of making, again yellow gold line base is carried out ε=55% tensile pre-deformation, on continuous extruder, two kinds of alloy wires are carried out continuously extruded compound in advance then, the sizing that stretches immediately carries out stretcher leveling at last.
Embodiment three: by " copper cash base, aluminum steel base one a rolling pre-compound drawing and setting " of the present invention operation, earlier by continuously extruded yellow gold line base and the 6063 aluminium alloy wire bases of making, again yellow gold line base is carried out ε=55% tensile pre-deformation, by milling train two kinds of metal wire rods are rolled pre-platform again then, sizing and aligning at last stretch.
Embodiment four: by " copper cash base, aluminum steel base-drawing and setting " of the present invention operation, earlier by continuously extruded yellow gold line base and the 6063 aluminium alloy wire bases of making, again yellow gold line base is carried out ε=55% tensile pre-deformation, on 5 tons of broaching machines, carry out compoundly by drawing die, carry out stretcher leveling at last.
