Abstract
The invention discloses a device for preparing a copper cladding aluminum composite wire, which is characterized in that the device is provided with a horizontal hydraulic driving device (1) and a tubular fixing frame (2) which is arranged at the output shaft direction of a hydraulic cylinder and a retaining ring ((3) which is arranged at the end of the tubular fixing frame (2). The device is suitable for making large sized copper cladding aluminum wires, intensively processed copper cladding aluminum lines and other special shaped copper cladding aluminum wires. The device is simple in structure, convenient in operation, high in production efficiency and suitable for mass production.
Description
Technical field:
The present invention relates to a kind of be used to the prepare copper clad aluminum wire of large size copper alclad line, deep processing and the equipment of other special-shaped copper-clad aluminium wires.
Background technology:
The copper cover aluminum wire rod is to be core body with aluminium, coats layer of copper thereon, makes copper and aluminium interface realize combining, and becomes the composite material of Metal Substrate core.It is compared with common copper cash, and identical conductive capability is arranged, and weight but pure copper wire is light, can make full use of abundant, cheap aluminium like this, saves rare relatively copper resource.Existing copper alclad wire material production method has: 1. aluminum steel copper-plating method, though this method process equipment is simpler, the copper composition of layer is impure, performance is more crisp, and combines insecurely between copper layer and the aluminium core, and the copper layer is difficult for one heart.2. roll crimping method, this method technology are comparatively complicated, and equipment investment is very big, so product cost is higher.3. quiet liquid extrusion, this method technology is more complicated also, requires very big extruding force (2000～4000 tons), thereby higher to equipment requirements, invests very greatly, and the length of lead is restricted, and can not even need the wire rod of production sufficient length.4. clad welded-hubbing, this method requires very high to the cleannes of blank, by blank lower and repeatedly annealing to the total working modulus of finished product, because the difference of huge Metal Mechanic Property between copper and the aluminium, be easy to cause in the little working modulus drawing course of processing, the part is peeled off and is reduced rate of finished products and electrical efficiency.Said method all is to be applicable to the fine composite conducting wire of producing small dimension, does not also produce the special equipment of big specification class copper cladding aluminum conductor at present.
Summary of the invention:
The present invention is directed to the above-mentioned deficiency of prior art, a kind of high efficiency, low cost are provided, be used to produce the special equipment of big specification class copper cladding aluminum conductor.
The technology of the present invention solution is: a kind of equipment for preparing cuprum-cladding-aluminium composite wire, be provided with horizontal hydraulic pressure drive unit 1, and in hydraulic cylinder output shaft direction tubulose fixed mount 2 is set, be provided with back-up ring 3 at tubulose fixed mount 2 ends.
Described tubulose fixed mount 2 can constitute by covering rubber etc. in the steel pipe, is used for fixing copper pipe.
The present invention is a horizontal type structure, during work, at first copper pipe is placed on tubulose fixed mount internal fixation, and back-up ring is spacing, by fluid pressure drive device the aluminium core is pushed in the copper pipe then, because the hydraulic system stable drive can guarantee the good combination with copper pipe and aluminium core.This apparatus structure is simple, and is easy to operate, and production efficiency is higher, adapts to requirements of mass production.
Description of drawings:
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment:
Below in conjunction with description of drawings the specific embodiment of the present invention.
As shown in Figure 1, a kind of equipment for preparing cuprum-cladding-aluminium composite wire is provided with horizontal hydraulic pressure drive unit 1, and fluid pressure drive device comprises hydraulic cylinder, in hydraulic cylinder output shaft direction tubulose fixed mount 2 is set, and tubulose fixed mount 2 constitutes by covering rubber in the steel pipe.Be provided with back-up ring 3 at tubulose fixed mount 2 ends.
Claims (2)
1, a kind of equipment for preparing cuprum-cladding-aluminium composite wire is characterized in that: be provided with horizontal hydraulic pressure drive unit (1), in hydraulic cylinder output shaft direction tubulose fixed mount (2) be set, be provided with back-up ring (3) at tubulose fixed mount (2) end.
2, the equipment of preparation cuprum-cladding-aluminium composite wire according to claim 1 is characterized in that: described tubulose fixed mount (2) is to constitute by covering rubber in the steel pipe.
