Description

Technical Field

[0001] The 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, which produces small-section metal wires by pulling the wire rod or wire blank out of the die hole of the wire drawing die under the action of drawing force. In the production and processing of copper wire, the metal blank is passed through the die hole to obtain copper wires of corresponding shapes and sizes. 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] Common metal wire drawing devices use traction to make the metal wire pass through a drawing head of corresponding diameter, and control the diameter of the drawing head to achieve metal wire processing of corresponding size. However, in the actual production process, due to the influence of traction and the toughness of the metal wire, when producing metal wires with smaller diameters, it is impossible to make the metal wire from thick to thin through a single drawing.

When the metal wire passes through the drawing head body 3 inside the two first installation ports 202 in turn, the metal wire is driven by the drawing traction assembly 5 to move along the trajectory in a U shape. Under the rotation of the winding roller, the metal wire moves to the drawing head body 3 inside the second installation port 203.

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. A number of first support columns are rotatably connected between the two support rings 401, and the peripheral side of the first support column is fixedly connected with a driving gear 404 meshing with the transmission outer gear ring 403. The cleaning and grinding ring 402 is fixedly connected with a transmission gear 405 meshing with the driving gear 404 through a 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 grinding ring 402 rotates synchronously, and the peripheral side of the metal wire is cleaned and polished.

The specific installation process is as follows: The transmission column 210 is manually pushed to drive the adjustment limit ring 207 to slide along the inside of the adjustment slot, the reset spring 208 is squeezed and the spherical engaging block 206 loses its restriction, and then the pulling head body 3 is installed in the corresponding first mounting port 202 or the second mounting port 203, and the transmission column 210 is released. Under the elastic recovery action of the reset 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 in the first mounting port 202 or the second mounting port 203, and is engaged with the corresponding engaging groove 301, thereby realizing the installation of the pulling head body 3.

[0043] After the drawing head 3 is installed, 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 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 connecting rod 407 are driven to rotate synchronously by a certain angle under the meshing action of the drive worm 410 and the drive turbine 406, and the adjusting connecting rod 407 is adjusted to rotate synchronously by a certain angle.

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 grinding 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.

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 opening 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 opening 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 to clamp and fix 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 so that the metal wire moves along a U-shaped trajectory.

[0048] During the process of the traction disc 501 pulling the metal wire, 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 surrounding side of the metal wire. The metal wire first passes through the drawing head body 3 inside the first installation 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 surrounding side of the metal wire is coated with lubricant again. When the metal wire passes through the drawing head body 3 inside the first installation 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 to drive the traction link 503 to rotate, so that the two clamping blocks 506 move away from each other and release 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.

[0049] 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 surrounding 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.

[0050] During the cleaning and polishing process of the pre-drawing metal wire 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 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 Fig.13 As shown in A1 in the figure, the portion of the delivery hose 601 between the two extrusion wheels 603 forms a closed chamber. As the delivery support link 602 rotates, the extrusion wheel 603 near the top fits with 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 closed chamber is opened (as shown in A1 in the figure). Fig.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 in 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 in the storage tank is continuously sucked into the delivery hose 601. As the delivery support link 602 continues to rotate, the squeezing wheel 603 originally near the bottom continues to move and squeeze the delivery hose 601, and the lubricant in 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). Fig.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 close to and squeeze the delivery hose 601 (as shown in FIG. Fig.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 to keep the lubricant inside the lubricating sponge block 204 sufficient.

[0051] Two sets of metal material production equipment are symmetrically arranged, and two different metals are drawn respectively to improve the compactness and surface quality of the stranded wire. Two symmetrically arranged clamping and fixing devices are used to clamp and fix the ends of the two metal wires after drawing respectively. The two clamping and fixing devices are controlled to rotate alternately to drive the two metal wires to be twisted together alternately in a spiral shape. When twisting, an appropriate twisting speed and a smaller twisting angle are used. 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 the 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.
