Description

Technical Field

[0001] The present invention belongs to the technical field of metal wire drawing, and in particular relates to a metal material production device and a working method. Background Art

[0002] Metal wire drawing is a metal plastic processing process that produces small-section metal wire by pulling the wire rod or wire blank through the die hole of the wire drawing die under the action of a drawing force. In the production and processing of copper wire, the metal blank is passed through the die hole to obtain copper wire of corresponding shape and size. During the drawing process, the cross-section of the copper wire is reduced and the length is increased, realizing the deformation from thick to thin. The drawn copper wire has precise size and smooth surface.

[0003] Conventional wire drawing devices use traction to force a wire through a drawing head of corresponding diameter, controlling the diameter of the drawing head to achieve the desired wire size. However, in actual production, due to the influence of traction and wire toughness, it is impossible to reduce the wire thickness from thick to thin in a single drawing when producing smaller diameter wires. Multiple drawing operations are required, which requires repeated operations, resulting in a cumbersome process and low production efficiency. To address this issue, we provide a metal material production device and working method to address the aforementioned technical issues. Summary of the Invention

[0036] For specific embodiment 1, please refer to Figure 1-13 The present invention is a metal material production equipment, including a support workbench 1. Specifically, a drawing support assembly 2 is fixedly installed on the upper surface of the support workbench 1. The drawing support assembly 2 includes a circular drawing support frame 201 fixedly connected to the upper surface of the support workbench 1. The circular drawing support frame 201 is provided with a first mounting port 202 and a second mounting port 203 on opposite sides. A drawing head 3 is movably installed inside the first mounting port 202 and the second mounting port 203. The drawing head 3 is snap-fitted with the corresponding first mounting port 202 and the second mounting port 203. The metal wire passes through the first mounting port 202 and the second mounting port 203. According to the size of the metal wire to be drawn, the drawing head 3 with the corresponding caliber is selected for installation, and the diameter of the drawing outlet port of the drawing head 3 decreases successively (the drawing direction of the metal wire is as shown in FIG. 2 ). Figure 2As shown); Lubrication support frames are fixedly connected to the two opposite outer side surfaces and the two opposite inner side walls of the ring-shaped drawing support frame 201, and the lubrication support frames correspond to the first mounting port 202 and the second mounting port 203, and a lubrication sponge block 204 is fixedly connected inside the lubrication support frame, and the lubrication sponge block 204 corresponds to the drawing inlet end of the corresponding drawing head body 3. A through hole is provided on the surface of the lubrication sponge block 204, and the lubrication sponge block 204 contains sufficient lubricant. The diameter of the through hole is smaller than the diameter of the metal wire before drawing. When the metal wire passes through the through hole, lubricant can be applied to its peripheral side surface. A pretreatment component 4 is fixedly installed on the side of one of the lubrication support frames away from the drawing head body 3.

[0037] Furthermore, the pretreatment component 4 includes two symmetrically rotatably arranged support rings 401, and several cleaning and polishing rings 402 are arranged between the two support rings 401; a drawing and traction component 5 is fixedly installed on the upper surface of the support workbench 1, and the drawing and traction component 5 is located on the side of the ring-shaped drawing support frame 201 away from the pretreatment component 4, and the outlet end of the drawing head body 3 inside the first installation port 202 is close to the drawing and traction component 5, and the outlet end of the drawing head body 3 inside the second installation port 203 is away from the drawing and traction component 5. A winding roller is rotatably arranged on the side of the ring-shaped drawing support frame 201 away from the drawing and traction component 5, which rewinds the metal wire while pulling the metal wire through rotation.

[0038] Furthermore, a lubrication adding assembly 6 is fixedly connected to the other two opposite inner side walls of the ring-shaped pulling support frame 201. The lubrication adding assembly 6 includes two symmetrically arranged conveying hoses 601 and two symmetrically rotatably arranged conveying support links 602. One end of the conveying hose 601 is connected to the corresponding lubricating sponge block 204. Both ends of the conveying support link 602 are rotatably connected to the extrusion wheel 603. The extrusion wheel 603 is tightly attached to and squeezes the corresponding conveying hose 601. The extrusion wheel 603 rotates and squeezes the conveying hose 601, and during the rotation process, it drives part of the lubricant to be conveyed to the lubricating sponge block 204.

[0039] The operation process of this embodiment is as follows: before drawing the metal wire (such as copper wire), according to the size of the metal wire (such as copper wire) to be drawn, the corresponding drawing head 3 is selected and installed in the first installation port 202 and the second installation port 203 in sequence according to the caliber of the drawing outlet end of the drawing head 3, and then the end of the metal wire is rolled so that the diameter of the end of the metal wire is consistent with the diameter of the metal wire to be drawn, so that the end of the metal wire can pass through the drawing head 3 in the first installation port 202 and the second installation port 203 in sequence; during the metal wire drawing process, the cleaning and grinding ring 402 is driven to rotate by driving the support ring 401, and at the same time, the cleaning and grinding ring 402 itself rotates to clean and grind the surface of the metal wire before drawing. The cleaned and polished metal wire then passes through the lubricating sponge block 204, and the metal wire is then drawn. Lubricant is applied to the side surface of the metal wire. After the metal wire passes through the drawing head body 3 inside the two first mounting ports 202 in turn, the metal wire is driven by the drawing traction assembly 5 to move in a U shape along the trajectory. Under the rotation of the winding roller, the metal wire moves to the drawing head body 3 inside the second mounting port 203. After the metal wire passes through the drawing head body 3 inside the two second mounting ports 203 in turn, it is wound on the winding roller; during the cleaning and polishing process, the conveying support link 602 rotates synchronously, driving the two extrusion wheels 603 to move synchronously. During the rotation, one of the extrusion wheels 603 rotates away from the conveying hose 601, and the other extrusion wheel 603 continues to squeeze the conveying hose 601, so that part of the lubricant inside the conveying hose 601 is conveyed to the corresponding lubricating sponge block 204, keeping the lubricant content inside the lubricating sponge block 204 sufficient.

[0040] For specific embodiment 2, please refer to Figure 2-9 On the basis of the specific embodiment 1, specifically, the first mounting port 202 and the second mounting port 203 are coaxially provided with an adjustment slot on the outside, and a spherical adjustment slot 205 is provided on the inner wall of the adjustment slot. The first mounting port 202 is connected to the corresponding spherical adjustment slot 205, and the second mounting port 203 is connected to the corresponding spherical adjustment slot 205. A spherical snap-fit ​​block 206 is provided inside the spherical adjustment slot 205, and an adjustment limit ring 207 is slidably provided inside the adjustment slot. A return spring 208 is fixedly connected between the adjustment limit ring 207 and the inner wall of the adjustment slot. Under the extrusion of the adjustment limit ring 207, the spherical snap-fit ​​block 206 is partially exposed outside the spherical adjustment slot 205; the upper surface of the return-shaped pulling support frame 201 is symmetrically provided with a transmission slot 209 connected to the corresponding adjustment slot, and a transmission column 210 is slidably provided inside the transmission slot 209, and the transmission column 210 is fixedly connected to the adjustment limit ring 207.

[0041] Furthermore, a plurality of engaging grooves 301 for engaging with the spherical engaging blocks 206 are provided on the side surface of the drawing head body 3. The drawing head body 3 has a conical chute structure near the drawing outlet end and a cylindrical chute structure near the drawing inlet end.

[0042] Furthermore, the pretreatment component 4 also includes an installation support frame symmetrically fixedly connected to a side of the corresponding lubrication support frame, and a transmission outer gear ring 403 is fixedly connected between the two installation support frames through a hollow support column. The support ring 401 close to the side of the circular drawing support frame 201 is rotatably connected to the peripheral side of the hollow support column, and a number of first support columns are rotatably connected between the two support rings 401. The peripheral side of the first support column is fixedly connected with a driving gear 404 meshing with the transmission outer gear ring 403, and the cleaning and polishing ring 402 is fixedly connected with a transmission gear 405 meshing with the driving gear 404 through the second support column. The support ring 401 is controlled to rotate, driving the driving gear 404 to move along the transmission outer gear ring 403. The driving gear 404 rotates, thereby driving the transmission gear 405 to rotate, so that the cleaning and polishing ring 402 rotates synchronously, and the peripheral side of the metal wire is cleaned and polished.

[0043] One of the first support columns is rotatably connected to a driving turbine 406 on one side, and an adjusting link 407 is fixedly connected to one side of the driving turbine 406, and one end of the adjusting link 407 is rotatably connected to the corresponding second support column. The other first support columns are rotatably connected to a V-shaped transmission link 408 on the other side, and one end of the V-shaped transmission link 408 is rotatably connected to an adjacent second support column. The other end of the V-shaped transmission link 408 is rotatably connected to an adjusting transmission link 409, and one end of the adjusting transmission link 409 is rotatably connected to the corresponding second support column; one side of the support ring 401 close to the transmission outer gear ring 403 is rotatably connected to a driving worm 410 through an ear plate, and the driving worm 410 is meshed with the driving turbine 406. A first driving motor is fixedly mounted on one side of the ear plate, and the output shaft of the first driving motor is fixedly connected to the driving worm 410.

[0044] Furthermore, a hollow sprocket 411 is fixedly connected to one side of the support ring 401 away from the side of the circular drawing support frame 201, and a rotating shaft is fixedly connected between the two opposite side surfaces of the circular drawing support frame 201. The rotating shaft passes through the circular drawing support frame 201 and is fixedly connected to a transmission sprocket 412 at one end. The transmission sprocket 412 and the hollow sprocket 411 are connected by a chain, and two driving bevel gears 413 are symmetrically fixedly connected to the side surfaces of the rotating shaft, and a second driving motor is fixedly connected to one side of the circular drawing support frame 201, and the output shaft of the second driving motor is fixedly connected to the rotating shaft.

[0045] The operation process of this embodiment is as follows: according to the size of the metal wire to be drawn, the corresponding drawing head 3 is selected and installed in the first installation port 202 and the second installation port 203 in sequence according to the diameter of the drawing outlet end. The specific installation process is as follows:

[0046] Manually push the transmission column 210 to drive the adjustment limit ring 207 to slide along the inside of the adjustment slot, the return spring 208 is squeezed and the spherical engaging block 206 loses its restriction, and then the pulling head body 3 is installed inside the corresponding first mounting port 202 or second mounting port 203, and the transmission column 210 is released. Under the elastic recovery action of the return spring 208, the adjustment limit ring 207 slides in the opposite direction along the inside of the adjustment slot and squeezes the spherical engaging block 206, so that the spherical engaging block 206 is partially located inside the first mounting port 202 or the second mounting port 203 and engages with the corresponding engaging groove 301, thereby realizing the installation of the pulling head body 3.

[0047] After the drawing head 3 is installed, the end of the metal wire is rolled so that the diameter of the metal wire end is consistent with the diameter of the metal wire to be drawn, so that the metal wire end can pass through the first installation opening 202 and the second installation opening 203 of the drawing head 3 in sequence (the metal wire moves in a U-shaped trajectory); at the same time, the first drive motor is started to drive the drive worm 410 to rotate, and the drive worm 406 and the adjusting link 407 are driven to rotate synchronously by a certain angle under the meshing action of the drive worm 410 and the drive turbine 406. During the rotation of 407, the corresponding second support column is driven to move, so that the transmission gear 405 moves along the driving gear 404, and the corresponding adjustment transmission link 409 rotates, driving the V-shaped transmission link 408 to rotate a certain angle, and then driving the adjacent transmission gear 405 to move along the driving gear 404. Under the action of the adjustment transmission link 409 and the V-shaped transmission link 408, the second support column moves synchronously, and then drives the cleaning and grinding ring 402 to move synchronously until the peripheral side of the cleaning and grinding ring 402 is in contact with the peripheral side of the metal wire.

[0048] During the metal wire drawing process, the second drive motor is started to drive the transmission sprocket 412 to rotate. Under the connection of the chain, the hollow sprocket 411 rotates synchronously, thereby driving the two support rings 401 to rotate synchronously. Under the meshing action of the transmission outer gear ring 403 and the driving gear 404, the driving gear 404 moves along the transmission outer gear ring 403, causing the driving gear 404 to rotate. Under the meshing action of the driving gear 404 and the transmission gear 405, the transmission gear 405 is driven to rotate, thereby causing the cleaning and polishing ring 402 to rotate synchronously, and the peripheral side of the metal wire before drawing is cleaned and polished. After the metal wire passes through the lubricating sponge block 204, the lubricating sponge block 204 applies lubricant to the peripheral side of the metal wire to facilitate the metal wire to pass through the drawing head body 3 for drawing.

[0049] For specific example three, please refer to Figure 10-13 On the basis of the specific embodiment 1 and the specific embodiment 2, specifically, the pulling and traction assembly 5 includes a support block symmetrically fixedly connected to the side of the circular pulling support frame 201 away from the pretreatment assembly 4, a support column is rotatably arranged between the two support blocks, a traction disc 501 is fixedly connected to the side surface of the support column, a third drive motor is fixedly installed on the lower surface of the support workbench 1, the output shaft of the third drive motor is fixedly connected to the support column, a traction groove 502 is opened on the side surface of the traction disc 501, a traction adjustment port is opened on the surface of the traction disc 501, two traction connecting rods 503 are symmetrically rotatably connected inside the traction adjustment port, and one end of the traction connecting rod 503 is fixedly connected to the transmission protrusion 5 04. One side of the transmission protrusion 504 is an inclined sliding surface structure; the supporting block is fixedly connected to supporting cross columns on both opposite sides, and one end of the supporting cross column is rotatably connected to an adjusting disk 505. The adjusting disk 505 corresponds to the first mounting port 202 and the second mounting port 203 respectively. The adjusting disk 505 slides with the inclined sliding surface of the transmission protrusion 504, and the transmission protrusion 504 moves synchronously with the traction disk 501. When it contacts the adjusting disk 505, the transmission protrusion 504 is squeezed by the adjusting disk 505 to drive the traction link 503 to rotate. The other end of the traction link 503 is rotatably connected to a clamping block 506, and an arc spring 507 is fixedly connected between the two traction links 503.

[0050] Furthermore, the lubrication adding component 6 also includes a lubrication support frame 604 fixedly connected to the inner wall of the circular drawing support frame 201, and the delivery hose 601 is fixedly installed on the inner wall of the lubrication support frame 604. The other end of the delivery hose 601 is located inside the storage tank where the lubricant is stored. One side of the lubrication support frame 604 is symmetrically connected to two adjusting gears 605, and the two adjusting gears 605 are engaged with each other; the adjusting gears 605 are fixedly connected to the corresponding delivery support link 602, and one side of one of the adjusting gears 605 is fixedly connected to a transmission bevel gear 606 through a rotating horizontal column, and the transmission bevel gear 606 is engaged with the corresponding drive bevel gear 413.

[0051] The operation process of this embodiment is as follows: the third drive motor is started to drive the traction disc 501 to rotate, and the traction link 503 rotates synchronously with the traction disc 501. When the traction disc 501 is at a certain angle, the inclined sliding surface of the transmission protrusion 504 contacts the adjustment disc 505 on the side close to the first installation port 202. As the traction disc 501 continues to rotate, the transmission protrusion 504 is squeezed by the adjustment disc 505 on the side close to the first installation port 202, driving the traction link 503 to rotate, the arc spring 507 is compressed, and the two clamping blocks 506 move away from each other. As the traction disc 501 moves, the two clamping blocks 506 are respectively located on the upper and lower sides of the metal wire. When the transmission protrusion 504 continues to move with the traction disc 501 and disengages from the adjustment disc 505 close to the first mounting port 202, the two clamping blocks 506 approach each other under the elastic recovery action of the arc spring 507, clamping and fixing the metal wire. As the traction disc 501 moves, the metal wire is driven to move synchronously for a distance. During the movement of the metal wire, the metal wire is pulled and the moving direction of the metal wire is adjusted at the same time, so that the metal wire moves along a U-shaped trajectory.

[0052] During the process of drawing the metal wire by the traction disc 501, the metal wire is cleaned and polished by the cleaning and polishing ring 402, and passes through the corresponding lubricating sponge block 204. The lubricating sponge block 204 applies lubricant to the peripheral side of the metal wire. The metal wire first passes through the drawing head body 3 inside the first mounting port 202 on the side close to the pretreatment component 4, so that the metal wire is initially drawn. As the metal wire moves, when the metal wire passes through the adjacent lubricating sponge block 204, the peripheral side of the metal wire is lubricated again. When the metal wire passes through the drawing head body 3 inside the first mounting port 202 on the side away from the pretreatment component 4, the metal wire is drawn for the second time. Driven by clamping, when the transmission protrusion 504 contacts the adjusting disc 505 and rotates 180°, the transmission protrusion 504 contacts the adjusting disc 505 close to the second mounting port 203. As the traction disc 501 rotates, the transmission protrusion 504 is squeezed by the adjusting disc 505 close to the second mounting port 203, driving the traction link 503 to rotate, so that the two clamping blocks 506 move away from each other and loosen the metal wire. As the traction disc 501 rotates, when the transmission protrusion 504 disengages from the adjusting disc 505 close to the second mounting port 203, the two clamping blocks 506 disengage from the metal wire, thereby adjusting the moving direction of the metal wire so that the metal wire continues to move along the U-shaped trajectory.

[0053] During the process of drawing the metal wire through the drawing head body 3 inside the two first installation ports 202, the winding roller rotates synchronously. Under the rotation of the winding roller, the metal wire passes through the drawing head body 3 inside the second installation port 203 in sequence, and before passing through the drawing head body 3, it first passes through the corresponding lubricating sponge block 204 for lubrication of the peripheral side surface, and then the corresponding drawing head body 3 performs the drawing operation. After passing through the drawing head body 3 close to the pretreatment component 4, the metal wire completes the drawing operation of the corresponding size and is wound on the winding roller.

[0054] During the process of cleaning and polishing the metal wire before drawing by the pre-treatment component 4, the rotation of the rotating shaft drives the two driving bevel gears 413 to rotate synchronously. Under the meshing action of the driving bevel gear 413 and the transmission bevel gear 606, the transmission bevel gear 606 is driven to rotate, and then the corresponding adjusting gear 605 is driven to rotate. Under the meshing action of the two adjusting gears 605, the two adjusting gears 605 rotate synchronously in opposite directions, driving the corresponding conveying support link 602 to rotate synchronously. During the rotation process of the conveying support link 602, in the initial state, the conveying support link 602 is in a vertical state, and the two extrusion wheels 603 are both close to and squeeze the conveying hose 601 (such as Figure 13 As shown in A1 in the figure, the portion of the delivery hose 601 between the two extrusion wheels 603 forms a sealed chamber. As the delivery support link 602 rotates, the extrusion wheel 603 near the top fits against the delivery hose 601 near the outlet end, and the extrusion wheel 603 near the bottom continues to squeeze the delivery hose 601, and the sealed chamber is opened (as shown in the figure). Figure 13 As shown in A2 in the figure), at the same time, under the movement and squeezing of the squeezing wheel 603 near the bottom, the lubricant inside the delivery hose 601 is transported forward for a distance. At the same time, a negative pressure environment is formed as the lubricant moves, so that the lubricant inside the storage tank is continuously sucked into the delivery hose 601. Under the continued rotation of the delivery support link 602, the squeezing wheel 603 originally near the bottom continues to move and squeeze the delivery hose 601, and the lubricant inside the delivery hose 601 is continuously transported forward. At the same time, the squeezing wheel 603 originally near the top moves to fit the delivery hose 601 near the inlet end (as shown in the figure). Figure 13 As shown in A3 in the figure, as the delivery support link 602 continues to rotate, the delivery support link 602 is in a vertical state again, and the two squeezing wheels 603 are again pressed against and squeeze the delivery hose 601 (as shown in FIG. Figure 13 As shown in A4 in the figure, the closed chamber is formed again. Since the outlet end of the delivery hose 601 is connected to the lubricating sponge block 204, the lubricant is continuously delivered to the lubricating sponge block 204, keeping the lubricant inside the lubricating sponge block 204 sufficient.

[0055] By symmetrically setting up two groups of metal material production equipment, two different metals are drawn respectively to improve the tightness and surface quality of the stranded wire. Two symmetrically set clamping and fixing devices are used to clamp and fix the ends of the two metal wires after drawing. By controlling the alternating rotation of the two clamping and fixing devices, the two metal wires are driven to be twisted together alternately in a spiral shape. When twisting, an appropriate twisting speed and a smaller twisting angle are adopted. An appropriate twisting speed can make the stranded wires more tightly combined. When the twisting speed is too fast, the stranded wire may become loose or broken, while when it is too slow, it may affect production efficiency. A smaller twisting angle can usually make the stranded wires tighter, and it needs to be adjusted according to the specific situation to avoid adding unnecessary twisting pressure.
