Embodiment

The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.

Embodiment 1

As shown in Figure 1, a kind of core of the big-and-middle drawing wire drawing machine of high speed high stability copper conductor is filled by wire drawing host 3, annealing Put 4, electric annealing device system, main motor drive system composition.

Main motor drive system includes wire drawing main motor 2 and driving belt, mainly to whole wire drawing host computer system and annealing Device operating provides power.Wire drawing main motor 2 is Frequency Drive motor, and the linear velocity of detection conductor speed is equipped with its traction wheel The actual linear velocity detected is fed back to wire drawing main motor 2 by detection device, the linear velocity detection device, and set with PLC The theoretical value of wire drawing main motor 2 is compared, and the rotating speed for correcting wire drawing main motor 2 is adjusted by frequency converter, makes actual linear velocity It is synchronous with theoretical value.I.e. when setting speed is 15m/min, when detection speed is 13m/min, system performs acceleration task, instead Execution deceleration task.There is provided the conversion of online rice number for PLC system according to detection device at the same time, when control setting rice is counted to certainly Stop after moving pre- reduction of speed.

Wire drawing main motor 2 reaches the copper conductor drawn from pay off rack 1 in 3 babinet of wire drawing host by feed belt , the basis that wire drawing host 3 depends on Medium drawing mach ine is processed the redesign of scope to meet to draw and tractive force.Wire drawing host At least two groups of moulds are installed on the die frame in 3 babinets, rotation pulling wheel is set between each mould, copper conductor is from previous group mould Later group mould is introduced by rotating pulling wheel after upper wire drawing, die frame is installed according to the different size of required copper conductor, Rotation pulling wheel is calculated different outside diameters according to wire drawing slippage, draw ratio and carries out copper conductor drawing.

Copper conductor after the completion of wire drawing is drawn by traction drive wheel 31, then through 32 separated time of branching wheel, is then passed to annealing Device 4,4 annealing device of annealing device refer to by forcing at copper conductor surface voltage, due to copper conductor resistance very little so as to produce Hair tonic heat makes copper conductor facilitate the processing of later process to change the mechanical performance of copper conductor elongation percentage.During annealing device 4 depends on The basis of machine drawing be processed scope heavy-duty machine design with meet different size annealing elongation percentage requirement.

Specific annealing process is as follows:Copper conductor from wire drawing host 3 initially enters preheating device 41, and preheating device 41 wraps Include at least two groups of preheating wheels, each preheating wheel and connect electric annealing device respectively, the temperature of preheating wheel is controlled by electric annealing device Degree, preheats copper conductor.

Then, copper conductor enters steam blanketing apparatus 42, anti-oxidant to copper conductor surface to protect, and prevents copper conductor oxygen Change.Steam blanketing apparatus 42 is by two groups of insulation conductive casters a 421 and the vapor cavity between two groups of insulation conductive casters a 421 422 compositions, each insulation conductive casters a 421 and vapor cavity 422 connect electric annealing device, pass through electric annealing device and control steaming Temperature in vapour cavity 422 is more than 500 DEG C.Insulation conductive casters a 421 be same equipment insulate in itself by electric annealing device Conducted with compound brush to insulation conductive casters a 421, insulation conductive casters a 421 and carry out contacting generation with copper conductor surface by nickel ring Fever.

Finally, copper conductor enters cooling device 43, and cooling device 43 is by 432 groups of insulation conductive casters b 431 and cooling duct Into insulation conductive casters b 431 and cooling duct 432 connect electric annealing device respectively, and copper conductor is utilized through cooling duct 432 The pressure washing copper conductor surface of water is realized and cooled.

Electric annealing device mainly carries out copper conductor direct current annealing, annealing ballast produce huge direct current KVA by with Apparatus insulated copper brush reaches insulation conductive casters and anneals.It is the most crucial finger of this workshop section that mass of copper conductor, which requires annealing elongation percentage, Mark, therefore the annealing elongation percentage of startup, parking, acceleration and deceleration is must pull against on anneal mode in control range, that is, press Industry will realize 0 annealing.

After the completion of annealing process, wire-crossing wheel 44 of the copper conductor after being arranged on cooling device 43 introduces tension adjustment frame 5, Tension adjustment frame 5 includes tension adjustment wheel 51, and swing rod 52 and driving cylinder 53, driving cylinder 53 connect tension force tune by swing rod 52 Whole wheel 51, driving cylinder 53 drive tension adjustment wheel 51 to move up and down to adjust the tension force suffered by copper conductor.Finally, by take-up Machine 6 winds copper conductor product.

The present invention is for cable electrical equipment of the special cable in processing copper conductor between big drawing machine and Medium drawing mach ine.

Above-described embodiment is not limit the invention in any way, every to be obtained by the way of equivalent substitution or equivalent transformation Technical solution all fall within protection scope of the present invention.
