Description
Technical field
The present invention relates to a kind of composite stock compression molding process in the mechanical facility, be applicable to the stock compression molding in the high-performance copper aluminium compound conductive bus bar process, belong to the metal metallurgy smelting technical field.
Background technology
The material of bus duct conductor is copper and aluminium matter.Along with rising steadily of international market cathode copper price, the production cost of copper conductor bus duct correspondingly increases, and has brought great financial burden to the user.But the limitation of aluminium matter conductor bus duct performance makes the user be absorbed in bottleneck in design and use.When homogenous material is difficult to satisfy the actual instructions for use of user, will have the different performance material and be combined with each other, come into one's own day by day with the composite that improves its comprehensive serviceability.Copper aluminium composite continuous casting conductive bus bar just is being based under these instructions for uses the novel conductive material of invention, its have conduct electricity very well, density is little, low cost and other advantages.But how to make two kinds of materials organically compound, improving its combination property is one of the important research direction in international material field.The compound conductive bus bar production method of visible report has following two kinds at present: (1) adopts external diameter is the clearance fit method of aluminum pipe for the copper pipe inner core, becomes the single composite bus bar of required appearance and size through the draw, drawing, smoothing, alignment; (2) cleaning wall thickness uniform copper pipe at copper pipe coated inner wall layer protective layer, under the protection of inert gas, heats copper pipe then, and then casting molten metal aluminium liquid within it.With the single composite bus bar that the blank that obtains is rolled, smoothing, alignment become required appearance and size.The above-mentioned method for preparing Copper Aluminium Composite Main Row exists all that quality conformance is low, poor stability, the more high shortcoming of production cost.In light of this situation, the enterprise of the production bus duct that comes out at the top as the domestic same industry, novel cuprum-cladding-aluminium stock compression molding method is invented out by exploration and practice constantly by my company, forms brand-new copper aluminium composite conducting material production technology.This continuous casting material is the widely-used technology ensuring that provides of high-performance composite materials for high-quality copper alclad composite electric busbar provides the approach of efficient production.
Summary of the invention
Technical problem to be solved by this invention is, a kind of die-casting process technology of copper cover aluminum composite blank is provided, and can produce high-quality, high performance copper cover aluminum compound conductive bus bar, has that technological process is short, the production efficiency advantages of higher.
For solving its technical problem, the technological process of Cai Yonging is as follows in process of production:
(1), external diameter copper pipe, the inner core aluminum pipe of the gapped matching relationship of cleaning; The matching copper that cleans out, that aluminum pipe carries out the draw is compound, eliminates the gap between two pipes; Copper, aluminium composite pipe are pressed into the composite bus bar blank on the 315t four-column hydraulic press; By the neat arrangement composite bus bar blank on the busbar heated holder in precalculated position;
(2), open the busbar heating furnace: design temperature is the liquidus temperature (〉=515 ℃) near the aluminium core in the stove.When confirming that the thermocouple displays temperature reaches design temperature, the composite bus bar blank on the heated holder is advanced in the stove successively by the workpiece pusher.When the composite bus bar blank of at first heating reaches predetermined heat time heating time, accept out compound row's blank by the busbar machine of connecting material and go to next procedure (the aluminium core among this moment compound row is near molten condition), by this working specification recycle feed, heating, discharging;
(3), the compound row's blank that is transferred by last process is instantaneous adjusts rolling that the flat milling train of three rollers of parameter moves in circles by the input of busbar delivery track: mill speed is for being controlled to be 10-30m/min, the single reduction in thickness is controlled at 10%-25% (blank that is 13mm thickness drops to about 6.5mm after rolling through 5 times), and the roll speed of service, varied in thickness parameter intuitively show by liquid crystal display;
(4), the compound row's blank of the rolling batch that finishes sends into the busbar annealing furnace, pours inert gas and carries out process annealing, annealing temperature is 250-450 ℃, annealing time 2.0-3.0h;
(5), annealed composite row is adopted the exquisite drawing of busbar profile mould of wolfram steel material, the busbar of finishing after this operation is required composite electric busbar finished product.
Beneficial effect of the present invention is:
(1) the initiative four-column hydraulic press is suppressed complex copper, aluminum pipe, and the billet size after can guaranteeing to suppress is even, accurate, for PLC busbar automatic feeding mechanism provides safeguard; (2) the composite bus bar heating furnace among next the present invention is the technology emphasis, the hot air apparatus of circulation can guarantee no matter which kind of variation takes place the composite bus bar billet size in the stove, the time that its aluminium core reaches molten condition can both remain on the same time period, for the copper aluminium composite electric busbar of producing all size provides good technology support; (3) change copper, aluminum pipe dimensions, copper stratum proportion, drawing-die size, can produce the copper aluminium composite electric busbar of different size, thickness; (4) a whole set of technological process draw, die casting, heating, flatly roll, annealing, drawing all easily realizes producing continuously, automaticity height, thereby improved production efficiency, reduced production cost; (5) technology non-environmental-pollution, the energy-conserving and environment-protective of being adopted among the present invention.
