Description

Technical Field

[0001] The present invention relates to the technical field of wire drawing devices, and in particular to an environmentally friendly wire drawing device and method for copper conductors. Background Art

[0002] The wire drawing device is a special equipment used exclusively in the wire and cable industry. It is mainly used to produce various types of copper conductors (including monofilaments and stranded wires). During the wire drawing process, the copper conductor needs to be drawn to reach the required cross-sectional area. This process is achieved through the wire drawing device.

[0003] The wire drawing device is mainly composed of a wire feeding mechanism, a wire drawing mechanism, a guiding mechanism, an annealing mechanism and a wire outlet mechanism. During the wire drawing process, the copper conductor is taken out from the reel and sent to the wire drawing area. When the copper conductor enters the wire drawing area, it is drawn under the action of the wire drawing mechanism. The guiding mechanism is responsible for guiding the direction of the copper conductor during the wire drawing process, and then the copper conductor after drawing is annealed to remove internal stress. Then the drawn copper conductor can be taken out from the wire drawing area and transported to the next process.

[0004] Copper wire drawing requires the copper wire to be forced through the die under the action of external force, the cross-sectional area is compressed, and the required cross-sectional area shape and size are obtained. In order to reduce the friction coefficient between the copper wire and the wire drawing die and take away the heat and copper powder generated on the surface of the die forming area and the sizing area, a wire drawing lubricant is required. The wire drawing lubricant can form a lubricating film between the wire and the die, thereby reducing the friction coefficient between the two, reducing energy loss, reducing die wear, and improving wire drawing efficiency. At the same time, it also helps to remove impurities on the surface of the wire, ensuring the quality of the wire leaving the factory.

[0005] However, as the number of uses increases, contaminants such as copper chips and fibers may be introduced into the lubricant, which will contaminate subsequent products, and the viscosity of the lubricant may increase, which will affect the lubrication effect. Summary of the invention

DETAILED DESCRIPTION

[0100] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

A die frame 6 is arranged between every two wire drawing wheels 4, and the die frame 6 is fixedly connected to the wire drawing frame 1. A wire drawing die 7 can be detachably installed on each die frame 6. The driving unit is installed on the wire drawing frame 1 to drive the wire drawing wheel 4 to rotate.

[0103] Specifically, in the wire drawing process, the corresponding wire drawing die 7 is first installed on the die frame 6, and the wire to be drawn is passed around multiple wire drawing wheels 4 in turn, the wire contacts the bottom of the wire ring groove 5, and the wire passes through the wire drawing die 7 until the end of the wire is connected to the traction device. At this time, the driving part and the traction device are started to make the wire start to move. Through the setting of the guide component, the movement of the wire can be more stable. The wire continuously passes through the wire drawing die 7. At this time, the wire is compressed so that the wire forms the required cross-sectional size. In this process, the wire will generate heat and generate friction with the wire drawing die 7. At this time, the feeding component is started to send the wire drawing lubricant into the liquid supply component. By turning on the liquid supply component, the friction on the wire can be reduced, and the heat generated by the wire during wire drawing can be taken away. The metal powder generated during wire drawing can also be cleaned up. At the same time, the recovery component is started to recover and process the sprayed wire drawing lubricant. There may still be wire drawing lubricant remaining on the wire after drawing. At this time, the drying component can be turned on to dry it.

[0107] Specifically, when it is necessary to spray the wire in the wire drawing process with the wire drawing lubricant, the wire drawing lubricant is discharged into the annular tube 17 and then discharged through the liquid supply nozzle 18. Before the wire enters the wire drawing die 7, it first passes through the arc groove 15 between the upper support frame 14 and the lower support frame 13. At this time, the wire contacts the cleaning block 16. Before the wire enters the cleaning block 16, the wire drawing lubricant is sprayed on the wire through the front liquid supply nozzle 18 to clean up the impurities on the wire or the metal powder attached to the wire after wire drawing, thereby cleaning the wire. Then, the cleaning block 16 is set to perform secondary cleaning on the wire. Then, the wire passing through the cleaning block 16 will be sprayed with the wire drawing lubricant by the rear liquid supply nozzle 18 before entering the wire drawing die 7. This has a lubricating effect during wire drawing and reduces the high temperature generated during wire drawing.

The plurality of exhaust slots 42 correspond one-to-one to the plurality of wire ring grooves 5, and outlet slots 43 are opened on both sides of each exhaust slot 42.

[0117] Specifically, after the wire drawing is completed, the wire is generally annealed to remove internal stress. However, if there is residual lubricant in the wire during the wire drawing process, problems may occur during annealing. First, the residual lubricant will affect the heating speed of the copper wire, which may cause local high or low temperatures, thereby affecting the uniformity of annealing. The chemical components in the lubricant may also react chemically with the copper wire to form an oxide layer, which will have an adverse effect on the subsequent wire drawing and annealing processes. Secondly, under high temperature conditions, the wire needs to consume more energy to heat up, which not only increases energy consumption but also increases production costs. Therefore, the wire after wire drawing must be dried. At this time, the blower 41 is started, and the blower 41 blows air into the wind rack 40. The air entering the wind rack 40 will be discharged from the air outlet slots 43 on both sides of the exhaust slot 42, thereby blowing the wire passing through the exhaust slot 42, thereby reducing the possibility of residual wire drawing lubricant adhering to the wire, and the air entering the discharge rack 3 will be discharged through the mesh plate 39 without affecting the wire.

[0118] To sum up, in the wire drawing process, the corresponding wire drawing die 7 is first installed on the die frame 6, and the wire to be drawn is passed around multiple wire drawing wheels 4 in turn, the wire contacts the bottom of the wire ring groove 5, and the wire passes through the wire drawing die 7 until the end of the wire is connected to the traction device. At this time, the first motor 11 and the traction device are started, and the first motor 11 drives one of the pulleys 10 to rotate, and the pulley 10 drives another pulley 10 to rotate through the setting of the transmission belt 9, thereby driving multiple wire drawing wheels 4 to rotate at the same time through the cooperation of the pulley 10 and the transmission belt 9, so that the wire begins to move.

[0119] The setting of the guide roller 37 can avoid the deviation of the wire during the wire drawing process. With the setting of the isolation column 38, when drawing multiple wires, the distribution of each wire can be more uniform, thereby improving the wire drawing quality and making the wire move more smoothly.

[0120] As the wire continuously passes through the wire drawing die 7, the wire is compressed, so that the wire forms the required cross-sectional size. In this process, the wire generates heat and produces friction with the wire drawing die 7. Before the wire enters the wire drawing die 7, it first passes through the arc groove 15 between the upper support frame 14 and the lower support frame 13. At this time, the wire contacts the cleaning block 16. Before the wire enters the cleaning block 16, the first water pump 20 is started. The first water pump 20 draws out the wire drawing lubricant in the liquid storage tank 19 and discharges it into the feeding pipe 21. The feeding pipe 21 passes through the first water pump 20. Through the setting of the connecting tube 22, it is discharged into the annular tube 17. At this time, the wire is sprayed with wire drawing lubricant through the front liquid supply nozzle 18 to clean up the impurities on the wire or the metal powder attached to the wire after wire drawing, thereby cleaning the wire. Then, through the setting of the cleaning block 16, the wire is cleaned for the second time. Then, the wire passing through the cleaning block 16 will be sprayed with wire drawing lubricant by the rear liquid supply nozzle 18 before entering the wire drawing die 7, which has a lubricating effect during wire drawing and reduces the high temperature generated during wire drawing.

[0121] As the spraying proceeds, the sprayed wire drawing lubricant will be mixed with impurities and metal powder and enter the recovery box 24. At this time, the second water pump 25 is started. The second water pump 25 draws out the wire drawing lubricant in the recovery box 24 through the setting of the recovery pipe 26, and discharges it into the liquid storage tank 19. At this time, through the setting of the air compressor 23, the air compressor 23 inflates the annular air pipe 27 through the exhaust pipe 28, and then turns on the nozzle 29 to spray a large number of bubbles. Due to the effect of surface tension, the metal powder will adhere to the bubbles and be collected together with the movement of the bubbles.

[0122] When collecting impurities in the wire drawing lubricant, the impurities will come to the surface of the wire drawing lubricant along with the bubbles. At this time, the second motor 33 is started, the second motor 33 drives the transmission screw 32 to rotate, the transmission screw 32 drives the transmission nut 34 to move, the transmission nut 34 drives the sliding frame 31 to move, and the sliding frame 31 can drive the scraper 35 to move, the scraper 35 will collect the impurities on the surface of the wire drawing lubricant and scrape them into one of the collection boxes 30. At this time, the spring 36 is set to make the scraper 35 move when it contacts the inclined surface of the collection box 30, so that the bottom of the scraper 35 always keeps in contact with the inclined surface position of the collection box 30. When the cleaning is completed, the second motor 33 can be reversed to make the sliding frame 31 move in the opposite direction, and the newly separated impurities can be scraped into another collection box 30, so as to facilitate the recycling of impurities.

[0123] After the wire drawing is completed, the blower 41 is started to blow air into the wind frame 40. The air entering the wind frame 40 will be discharged from the air outlet slots 43 on both sides of the exhaust slot 42, thereby blowing air on the wire passing through the exhaust slot 42, thereby reducing the possibility of residual wire drawing lubricant adhering to the wire, and the air entering the discharging frame 3 will be discharged through the mesh plate 39 and will not affect the wire.

[0137] Step 12: Processing: The air compressor 23 inflates the annular air pipe 27 through the exhaust pipe 28, and then opens the nozzle 29 to spray out a large number of bubbles. Due to the effect of surface tension, the metal powder will adhere to the bubbles and be collected together with the movement of the bubbles.

[0138] The thirteenth step is collecting. The second motor 33 is started. The second motor 33 drives the transmission screw 32 to rotate. The transmission screw 32 drives the transmission nut 34 to move. The transmission nut 34 drives the sliding frame 31 to move. The sliding frame 31 can drive the scraper 35 to move. The scraper 35 will collect the impurities on the surface of the wire drawing lubricant and scrape them into one of the collection boxes 30. At this time, the spring 36 is set to make the scraper 35 move when it contacts the inclined surface of the collection box 30, so that the bottom of the scraper 35 always keeps in contact with the inclined surface position of the collection box 30. When the cleaning is completed, the second motor 33 can be reversed to make the sliding frame 31 move in the opposite direction to scrape the newly separated impurities into another collection box 30, so as to facilitate the recycling of impurities.

[0139] Step 14: Drying. Start the blower 41 to blow air into the wind frame 40. The air entering the wind frame 40 will be discharged from the air outlet slots 43 on both sides of the exhaust slot 42, thereby blowing air to the wire passing through the exhaust slot 42, thereby reducing the possibility of residual wire drawing lubricant adhering to the wire;
