Abstract
The utility model relates to a high conductivity and high strength copper aluminum composite contact wire used in magnetic suspension railway power receiving catenary. The characteristic is: a copper of the locomotive conductive arch contact part and an aluminum of aluminum clip contact part are composite molded to be an integral wire rod by multiple fastening structure. Due to a dovetail groove multiple fastening structure of copper and aluminum, a binding force of the two metals is significantly enhanced. Especially when the contact wire is produced by plastic deformation method, the respective elastic deformation energy storage at the fastening position can make the two metals entangled each other and tightly combined. A comprehensive conductivity of the utility model is 65% IACS to 105% IACS, a copper aluminum section area proportion and a copper alloy grade and a aluminum grade can be changed to reach various conductivity demands; a hardness of the utility model work part (namely the copper alloy part in a sliding friction with the conductive arch) is HB 90 to 200, the hardness demand can be reached as required by changing copper alloy grade, changing processing rate and special heat treatment; a copper aluminum binding force of the utility model is 400 to 550 N/cm, which can completely meet the demands of low, medium and high speed magnetic suspension railway.
Description
Technical field
The utility model relates to high conductivity, the high strength copper-aluminum composite contact wire that a kind of magnetic suspended railway contact line is used.
Background technology
Along with the develop rapidly of Chinese national economy, China introduces speed per hour up to the magnetic-levitation train of 300-500 kilometer just in test, because specification requirement is very high, fails to produce magnetic suspended railway contact line contact wire to domestic the present; The present magnetic railway in the Shanghai of introducing by Germany, it is electrically contacted the net contact wire and is had only steel aluminium contact wire, and the conductance of steel aluminium contact wire is not good enough, and current loss is big in the operation process.
Summary of the invention
Electrically contacted the deficiency of net with contact wire in order to overcome present magnetic suspended railway, the utility model provides a kind of high conductivity, high strength copper-aluminum composite contact wire.
The technical scheme that its technical problem that solves the utility model adopts is: with the aluminium (2) of the copper (1) of locomotive pantograph contact portion and aluminium clip contact portion be a whole wire rod through fastening structure (3) composite molding repeatedly; Repeatedly fastening structure (3) is an oat tail groove structure; But the copper of copper-aluminum composite contact wire and aluminium fine copper and aluminium is copper alloy and aluminium alloy also.
The beneficial effects of the utility model are, owing to adopted repeatedly fastening structure obviously to strengthen the adhesion of two kinds of metals, when particularly utilizing the plastic deformation method to produce the composite contact wire of this kind section structure, at two kinds of metals of fastening position separately strain energy storage is arranged, two kinds of metals are tangled mutually, in conjunction with tight.The comprehensive conductance of the copper-aluminum composite contact wire of being produced is 70%IACS～90%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 portion 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; Product size is accurate, meet the dimension precision requirement in the national standard " electric traction contact wire ", contact wire any surface finish, not coarse, glacing flatness height in the longitudinal direction, satisfy railway and lay requirement, the copper-aluminum composite contact wire copper aluminium engaging force that the technology of the present invention is produced can reach 400～550N/cm, and possesses advantages of higher tensile strength and elongation simultaneously, can satisfy the requirement of low speed, middling speed, high-speed magnetic levitation railway fully.
Below in conjunction with drawings and Examples the utility model is further specified.
Description of drawings
Fig. 1 is the copper-aluminum composite contact wire structural representation;
Among the figure 1, copper or copper alloy, 2 aluminum or aluminum alloy, more than 3 fastening structure
Embodiment 1:
Utilize plastic deformation with the copper part line base close, the contact wire that two kinds of line bases is combined into one by plastic deformation again among silver alloy copper base and 6063 aluminium base predeformation one-tenth and Fig. 1 with the aluminum portions shape and size.The section of product is structure shown in Figure 1, the product surface of being produced is very good, the area of copper aluminium ratio is about 3: 2 on the section, conductance is 82%IACS, bond strength reaches 462N/cm, the case hardness of silver-bearing copper part reaches HB110, and the glacing flatness height satisfies the performance requirement of use occasion to this contact wire.
