Description
Technical field
The present invention relates to a kind of composite material production technology, particularly a kind of copper-clad aluminum conductor, copper cladding aluminium pipe production process and equipment thereof.Be to produce copper-clad aluminum conductor and copper cladding aluminium pipe preferred production technology and equipment.
Background technology
As everyone knows, copper-clad aluminum conductor and copper cladding aluminium pipe are copper aluminum composite materials, are the light weight that the said goods possesses aluminium, possess the conductivity of copper simultaneously again, and the advantage that antiseptic property is good is widely used in radio frequency cable, and electromagnetic wire is compiled the aluminium shielding conductor, on the products such as power line.Reduce cost, economize on resources.Copper cladding aluminium pipe promptly can be used for the suspension wire of radio frequency cable, can be used for products such as air-conditioning again and does condenser pipe usefulness, and the copper cover aluminum product is novel instead of copper, the best of aluminium, the most rising product.Because the scarcity of world's copper resource, the development of world economy demand is increasing, and the copper valency rapidly goes up at present, and seeking the alternative fine copper of best copper aluminum composite material is the current matter of great urgency, also is the demand on the situation.Yet produce copper-clad aluminum conductor at present is traditional force deformation technology.Roll compacting method production copper-clad aluminum conductor is lived aluminum core line with the copper strips while double team of both sides and is formed in the roll compacting of argon shield environment by milling train, under pressure, realize controlling golden combination between the two, again through Milling Machine with the copper bound mill off of joint the blank copper-clad aluminum conductor, the drawn machine carries out just becoming the copper-clad aluminum conductor finished product after repeatedly drawing and the heat treatment step in addition, although described method energy production of copper alclad base line, but still exist the base line that only is suitable for producing little line footpath, low if the base line in the big line of production footpath obviously exposes copper product with rate, the unfavorable shortcoming of outer copper strips uniformity; And for example clad welded is wrapped in a fine copper band in it to the aluminium core bar by becoming the pipe shape step by step; under inert gas shielding, weld automatically; finish the production of copper cover aluminum base line through finishing and winding again, subsequently again through repeatedly drawing and heat treatment step become the copper-clad aluminum conductor finished product.Though the copper-clad aluminum conductor that this method is produced has copper layer good uniformity, save copper material, speed of production is advantage faster.But also exist such as need just reaching through repeatedly stretching after the welding and control gold in conjunction with the increasing production cost consuming time of not only taking a lot of work.And because of its stretching mold pressing often surperficial easy damaged etc. not as the defective of people's will.Particularly its total deformation reaches and just can reach more than 87% to control the requirement of golden combination, therefore reaches metallurgical binding stretching quality before and is difficult to control, has increased difficulty to drawing process.As not solving the quality stability that will influence copper-clad aluminum conductor as early as possible, this has caused stakeholder's serious concern in the industry, and drops into scientific and technical personnel and financial resources, but has not yet to see the relevant report that successfully solves.
Summary of the invention
The present invention is directed to the problem that prior art exists, a kind of copper-clad aluminum conductor, copper cladding aluminium pipe production process and equipment thereof are provided, manufacturing process advantages of simple, saving copper material, reduce operation and obviously shorten the time that manufactures a finished product, guarantee the copper layer good uniformity of copper-clad aluminum conductor, both reach metallurgical binding, steady quality preferably, the production efficiency height, the production technology of the copper-clad aluminum conductor that obviously reduces production costs (pipe).
Another object of the present invention provides a kind of mutually equipment of production copper-clad aluminum conductor (pipe) with it.
Production technology of the present invention comprises following processing step:
A, directly determine billet size according to design lines;
B, copper strips and aluminium carry out removing surface respectively before entering clad welded mechanism;
C, clad welded: copper strips and the termination that is placed on the aluminium core above it sent to coat in the mechanism from feeding port after Overmolded, weld by automatic welded tube mill;
D, heat with line footpath size through frequency heating device and to determine heating-up temperature;
E, after the d operation, in official hour, carry out a drawing and reach design lines footpath by stretching-machine.
Heating-up temperature in the described d operation is 600-680 ℃.
Also can increase by one annealing operation after the described e operation.
The copper-clad aluminum conductor clad welded equipment that is used for process of the present invention, form by blank surface descaling machine, clad welded mechanism, stretching-machine, its described clad welded mechanism places the automatic welded tube mill of inert gas environment and by several multistage vertical forming rollers that its die cavity is reduced step by step and the coating mechanism that is made of several most horizontal form rollers that its die cavity is reduced step by step, also comprises the online heater that places after the automatic welded tube mill.
Described heater is an intermediate frequency heater.
The present invention compared with prior art carries out online heating process owing to adopted after welding.Not only be beneficial to and reduced the stability that the drawing number of times reaches metallurgical binding fast but also be beneficial to product quality and also solved the restive problem of stretching quality before reaching metallurgical binding in the past simultaneously, simplifying technology enhances productivity, need not the trimming burr and save copper material, when particularly processing big line footpath, its more obvious raising stock utilization, obviously reduce manufacturing cost, simultaneously the wide line footpath that varies in size except processing of the scope of application is also can process plurality of advantages and good effect such as copper cladding aluminium pipe, and obtain testing prove.Technology is reasonable in addition, and continuity is good, shortens the time that manufactures a finished product.
Description of drawings
Accompanying drawing is the structural representation of the inventive method production equipment.
