Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of wire drawing equipment, and relates to a rough copper wire drawing device for vehicle gauge level high-power devices. BACKGROUND

[0002] Copper wire has good electrical conductivity and is often used to manufacture wires and cables. In order to make standard-diameter copper wire suitable for wires and cables of different specifications, wire drawing equipment is usually used to draw copper wire into various required specifications.

[0003] According to the search, a wire drawing machine for copper wire processing is disclosed in Chinese authorized patent CN218982706U. The patent realizes the cooling of the wire drawing die by setting a cooling flushing structure and a spraying pipe. When in use, one end of the copper wire on the wire drawing roller passes through the wire drawing die until reaching the other group of wire drawing rollers. It can be known that the existing copper wire drawing equipment first draws the copper wire from the wire drawing roller for unwinding, then makes the copper wire pass through the wire drawing die and is collected on the wire drawing roller for winding, then makes the wire drawing roller for winding rotate, so that the copper wire on the wire drawing roller for unwinding passes through the wire drawing hole with gradually reduced internal diameter of the wire drawing die, and then is plastically deformed, and finally is gradually wound on the surface of the wire drawing roller for winding. Through the above actions, the wire drawing work of the copper wire is realized. However, in the above process, there is a certain distance between the wire drawing roller for winding and the wire drawing die, so that the copper wire at the position between the two is easily affected by external factors (such as air flow), and then is shaken. Since one end of the copper wire at the position enters the wire drawing die and is plastically deformed, the shaken copper wire will generate a deflection force on the copper wire entering the wire drawing die, so that the copper wire at the position is prone to breakage, thereby affecting the processing efficiency of the copper wire.

There are two guiding mechanisms 21, which are respectively located at the entrance and exit of the wire drawing machine 2; the cleaning mechanism is installed at the entrance of the wire drawing machine 2 to clean and disinfect the incoming crude copper wire to be processed. After cleaning, the crude copper wire to be processed enters the wire drawing mechanism for drawing and is then wound onto the second winding machine 3 under the guidance of the guiding mechanism 21 at the exit.

[0029] The guiding mechanism 21 includes a guiding frame 202, a guiding roller 201 and a guiding robotic arm 203. One end of the guiding robotic arm 203 is arranged on one side of the wire drawing machine 2, and the other end of the guiding robotic arm 203 is connected to the guiding frame 202.

The roller 22 disinfects and sterilizes the coarse copper wire through the sterilization area, and cleans the coarse copper wire through the friction between the cleaning wheel and the cleaning cotton block 23, so that the cleaning is thorough.

[0031] The wire drawing mechanism includes a box body, in which a multi-stage wire drawing module is arranged. The multi-stage wire drawing module is composed of a plurality of wire drawing modules 28 arranged in sequence. The wire drawing module 28 includes two winding cone wheels 27 and a grinding wheel 26. A wire drawing die 29 is arranged between the two winding cone wheels 27, and the wire drawing die 29 is installed on the inner side of the box body through a slot; a tension pulley is also provided on one side of the winding cone wheel 27, and the tension pulley is used to tension the copper wire. After passing through the wire drawing die 29, the copper wire is stretched to a set size, and the grinding wheel 26 is used to grind and polish the stretched copper wire, and a heat dissipation interlayer containing coolant is provided behind each grinding wheel 26. The heat dissipation interlayer is connected to a heat dissipation pipe to form a circulation loop. The heat dissipation interlayer is used to cool the polished copper wire. After passing through the heat dissipation interlayer, the copper wire enters the next group of wire drawing modules 28 for stretching. The multi-stage wire drawing module can realize the graded stretching of the thick copper wire and can smoothly complete the copper wire stretching work.

[0032] The first winding machine 1 comprises a base 11, a slide rail is mounted on the base 11, a first sliding block 12 and a second sliding block 13 are arranged on the slide rail, a plurality of wire reel mounting wheels are arranged on the inner side surfaces of the first sliding block 12 and the second sliding block 13, wire reels 15 are arranged on the wire reel mounting wheels, and copper wires are wound on the wire reels 15. At least one wire reel mounting wheel is connected with a winding motor at one end, the winding motor is used to drive the wire reel mounting wheel to rotate, so as to drive the wire reel 15 to rotate. A tread made of rubber material is sleeved on the surface of the wire reel mounting wheel, so as to increase the friction. When the resistance of the wire reel 15 is large, the wire reel mounting wheel can slide relative to the wire reel 15 to avoid breaking the copper wire. Limiting blocks 14 are arranged on the right side surfaces of the first sliding block 12 and the second sliding block 13. The limiting blocks 14 can limit the wire reel 15, so as to ensure the stability of the rotation of the wire reel 15. The limiting blocks 14 are provided with semicircular limiting grooves at the bottom. The limiting grooves can cooperate with the rotating shafts of the wire reels 15, so as to ensure the stability of the rotation of the rotating shafts. The limiting blocks 14 can also adjust the height of the limiting blocks 14 by using a limiting motor, so as to cooperate with wire reels 15 of different sizes.

[0033] The bottom ends of the first sliding block 12 and the second sliding block 13 are provided with a driving mechanism. The driving mechanism comprises a driving motor and a lead screw. The driving motor drives the lead screw to rotate. The lead screw is installed at the bottom of the first sliding block 12 and the second sliding block 13. The rotation of the lead screw can drive the first sliding block 12 and the second sliding block 13 to move along the slide rail. The first winding machine 1 can move along the slide rail during the winding process. The movement speed of the first sliding block 12 and the second sliding block 13 can be adjusted according to the winding speed by using a controller for pre-programming. In use, the plurality of wire reel mounting wheels cooperate to support and drive the wire reel 15. The winding motor drives the wire reel mounting wheel to rotate. The driving mechanism drives the first sliding block 12 and the second sliding block 13 to move along the slide rail. The wire reel follows the first sliding block 12 and the second sliding block 13 to move along the slide rail. This is beneficial to the smooth transition of the copper wire to be drawn from one end to the other end of the wire reel 15 during the winding process, so as to ensure that the copper wire to be drawn is wound neatly. The first winding machine 1 is used to release the copper wire to be drawn. The second winding machine 3 is used to wind the copper wire to be drawn after drawing. The second winding machine 3 and the first winding machine 1 have the same structure.

[0034] Firstly, the copper wire to be drawn which needs to be drawn is wound on the first winding machine 1. Then, the copper wire to be drawn is pre-drawn, and sequentially passes through a guide mechanism 21, a cleaning mechanism and a drawing mechanism arranged on the drawing machine 2. Finally, the copper wire is fixed on the second winding machine 3. Then, the power supply of the winding motor is started, so that the two winding machines perform the transfer work of the copper wire.

[0035] In the process of copper wire transfer, first through the cleaning mechanism, when the rough copper wire to be drawn enters the cleaning mechanism from one of the wire passing ports, it passes through the rotating roller 22, and then exits the cleaning mechanism from another wire passing port. During this period, the rough copper wire to be drawn is always immersed in the chemical cleaning agent in the sterilization area of the cleaning cylinder. After being compressed by the rotating roller 22, the rough copper wire to be drawn is in full contact with the chemical cleaning agent, thereby removing the oxidation layer on the surface of the rough copper wire to be drawn and preventing the oxidation layer from damaging the drawing die 29 during the drawing process.

[0036] After the copper wire leaves the sterilization area of the cleaning cylinder, the rough copper wire to be drawn, from which the surface oxidation layer has been washed off, enters the wire passing groove from one of the L-shaped wire passing ports. The water in the storage cavity of the cleaning area is heated by the heat from the heat dissipation interlayer of the cleaning area, and the water in the storage cavity expands and rises into the wire passing groove. The hot water in the wire passing groove washes off the oily substances on the surface of the rough copper wire to be drawn, and the rough copper wire to be drawn, from which the surfactant and corrosion inhibitor have been washed off, is wiped clean by the cleaning roller and the cleaning cotton block 23 before entering the drawing mechanism for drawing treatment.

[0037] The rough copper wire drawing device for a vehicle-grade high-power device of the embodiment uses two oppositely arranged first winding machines 1 and second winding machines 3. Since there is a certain distance between the winding machines and the drawing die, the copper wire positioned between the two is easily affected by external factors and thus shakes. Therefore, the embodiment sets a guide mechanism 21 and a slider that can adjust the position of the winding machine, so that the copper wire entering the inside of the drawing machine 2 can be relatively stable, and the degree of angular deviation of the copper wire is reduced. The copper wire after entering the drawing machine 2 is first treated by the cleaning mechanism. In this process, the copper wire can be positioned by the multiple pulleys arranged in the cleaning mechanism, and the influence of external factors can be significantly reduced during the treatment process in the cleaning mechanism. Then, multi-stage stretching is performed during the drawing process, and polishing and cooling treatment are performed each time to reduce the influence of temperature on the drawing process. Moreover, the drawing precision can be significantly improved during each polishing process, the copper wire after each stage of stretching meets the processing requirements, the influence of plastic deformation is reduced, and copper wire breakage is effectively avoided during each stage of stretching, thereby improving the processing efficiency and precision of the copper wire.

[0038] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
