Description
Technical Field
[0001] The present invention relates to the technical field of production equipment for bimetal composite wires, specifically an efficient production line for bimetal composite wires. Background Art
[0002] Currently, the main production method for billet of bimetal composite wires such as copper-clad aluminum and copper-clad steel is the cladding welding-drawing method. The specific production method is to draw an aluminum rod (steel rod) through an aluminum rod drawing machine, then manually degrease the drawn aluminum rod by alkaline water immersion, and finally wind the aluminum rod on an aluminum rod pay-off stand; at the same time, the copper strip on the copper strip pay-off stand is pretreated through a cleaning tank, a copper strip dryer, a copper strip edge trimming machine, and a copper strip grinding machine; finally, the aluminum rod and the copper strip pass through a welding device composed of a cladding forming machine and a welding device, a composite billet drawing machine, a take-up machine, etc., that is, the continuously moving forward (transported by a conveying device) copper strip is rolled into a circular tube around the aluminum core wire or steel core wire by the cladding forming machine, and then under the argon protection state, the longitudinal seam of the copper tube is welded by a welding device (argon arc welding), and then multi-pass drawing is carried out through the composite billet drawing machine to form a metallurgically bonded bimetal composite wire.
[0003] Since the copper strip is loaded on the pay-off stand in coils, each coil is only a few hundred meters long. After welding each coil of copper strip or aluminum rod, it is necessary to stop the machine and replace another coil of copper strip or aluminum rod, so that the cladding welding production process cannot be carried out continuously, the downtime is relatively long, the production efficiency of the billet is reduced, and at the same time, it is impossible to produce billets of large coil weight for bimetal composite wires.

[0009] Preferably, an aluminum rod feeding rack is arranged on the left side of the connecting seat, an aluminum rod coil is arranged above the inside of the aluminum rod feeding rack, and an aluminum rod docking machine is arranged between the aluminum rod feeding rack and the aluminum rod drawing machine.
[0010] Preferably, guide rods are fixedly connected to both sides inside the telescopic groove, and the outside of the guide rods is slidably connected to both sides of the telescopic frame.

[0012] Preferably, both sides inside the cleaning tank are rotatably connected with rollers, and both sides at the top of the cleaning tank are rotatably connected with guide rollers.
[0013] Working principle: The aluminum rod is wound into a coil and sleeved on the aluminum rod feeding rack. It enters the aluminum rod drawing machine through the upper rollers of the aluminum rod feeding rack for drawing to make its size meet the feeding requirements of the peeling device. The aluminum rod after being peeled by the peeling device already meets the requirements of copper-aluminum metallurgical bonding. When the aluminum rod coil on the aluminum rod feeding rack is about to be used up, the tail end of it is welded to the starting end of the aluminum rod on another aluminum rod feeding rack by using an aluminum rod butt welding machine (resistance butt welding machine). The copper strip is placed on the copper strip feeding rack in coils. When a coil of copper strip is about to be used up, its tail end can be welded to the starting end of another coil of copper strip on the copper strip butt welding machine. To ensure that the production line does not stop during the copper strip butt joint, a copper strip storage is provided between the copper strip butt welding machine and the cleaning tank. The copper strip is conveyed into the copper strip storage by the first conveyor roller and the second conveyor roller, and then conveyed into the cleaning tank through the conveyor roller (not marked in the figure) on the right side of the top of the copper strip storage. The rotation speed of the regulating motor is adjusted so that the conveying speed of the first conveyor roller and the second conveyor roller for the copper strip is greater than the output speed of the copper strip, and the excess copper strip is stacked in the copper strip storage 1. The length of the stacked copper strip should at least meet the requirement of the time (min) required for butt joint of the copper strip × the covering and welding speed (m / min). Thus, the conveying speed of the driving roller for the copper strip and the height and length dimensions of the copper strip storage are determined. When butt jointing the copper strip, the motor stops, and the end of the previous coil of copper strip is butted with the starting end of the next coil of copper strip. At this time, the welding device does not stop, and the used copper strip is supplied by the copper strip stacked in the copper strip storage. After the copper strip is connected, the motor is started to make the conveying speed of the first conveyor roller and the second conveyor roller for the copper strip greater than the output speed of the copper strip, and the excess copper strip is stacked in the copper strip storage again. It circulates in turn to continuously feed the copper strip into the welding device, which can ensure the continuous production of the production line, significantly improve the production efficiency of the wire blank, and drive the second conveyor roller to rotate by the motor to cooperate with the first conveyor roller to take in the copper strip on the copper strip feeding rack into the copper strip storage. According to the thickness of different copper strips, the first conveyor roller can squeeze the spring through the telescopic frame so that the sliding grooves on both sides of the U-shaped telescopic frame slide along the guide rods in the telescopic grooves, so that the first conveyor roller can adapt to copper strips of different thicknesses and convey them. The copper strip coming out of the copper strip storage enters the cleaning tank and is conveyed in cooperation with the rotating roller and the guide roller. When passing between the two cleaning rollers, the surface of the copper strip can be cleaned, and by rotating the knob to drive the bidirectional threaded rod to rotate, the two moving blocks can be driven to move relatively or away from each other through the bidirectional threaded rod to adjust the distance between the two cleaning rollers. The mounting seat can also be conveniently disassembled by screws. When the cleaned copper strip is conveyed above, it will pass through the water absorption plate, and the water on the surface of the copper strip can be treated in cooperation with the blower on the right side of the cleaning tank. After the aluminum rod and the copper strip enter the covering and forming machine, they are rolled into a circular tube shape, and the aluminum rod is covered therein. Then, the longitudinal seam of the copper tube is welded by the welding device. Finally, the welded wire blank is drawn by the drawing machine and taken up by the take-up machine, and the whole production process is completed.
[0014] The present invention provides a high-efficiency production line for bimetallic composite wire. It has the following beneficial effects:
[0015] 1. The present invention works by the mutual cooperation of a cleaning tank, rotating rollers, guiding rollers, water-absorbing plates, mounting seats, mounting grooves, bidirectional threaded rods, knobs, moving blocks, cleaning rollers, screws, and fans. When the copper strip passes through between the two cleaning rollers, the surface of the copper strip can be cleaned. By rotating the knob, the bidirectional threaded rod is driven to rotate, and the two moving blocks can be driven to move relatively or away from each other by the bidirectional threaded rod to adjust the distance between the two cleaning rollers. The mounting seat can also be conveniently disassembled by the screws. When the copper strip after cleaning is conveyed above, it will pass through the water-absorbing plate, and the water on the surface of the copper strip can be treated in cooperation with the fan on the right side of the cleaning tank.
[0016] 2. The present invention can complete the continuous feeding of the aluminum rod and the copper strip through the aluminum rod docking machine and the copper strip docking machine. By storing a part of the copper strip in the provided copper strip storage, the end of the previous copper strip can be docked with the start end of the next copper strip by the copper strip docking machine under the condition that the welding device does not stop, so that the copper strip can be continuously fed into the welding device, ensuring the continuous production of the production line. In addition, the first driving roller on the left side of the copper strip storage and the second driving roller can also adapt to copper strips of different thicknesses and convey them, with stronger applicability.
