Technical Field
[0001] This utility model relates to the field of coarse copper wire processing technology, specifically a drawing die based on a coarse copper wire drawing machine. Background Technology
[0002] Copper wire refers to wire made from hot-rolled copper rods that are not annealed, but smaller wires may require intermediate annealing. It can be used for weaving mesh, cables, or copper brush filters. When processing and using coarse copper wire, the drawing die of a drawing machine is required to draw the coarse copper wire.
[0003] For example, a wire drawing die based on a coarse copper wire drawing machine, with authorization announcement number CN214919295U, includes a die sleeve, a support platform is provided on the lower inner side of the die sleeve, an annular hole is provided on the inner side of the support platform, and an outlet hole is provided on the lower side of the annular hole. Although the above document can realize the heat generated by the friction between the workpiece and the die core to be transferred to the die sleeve, the cooling cavity in the die sleeve absorbs the heat, thereby achieving the effect of heat dissipation for the device; However, when using wire drawing dies, different diameter copper wires are drawn by changing the die cores with different apertures. Since the drawing machine must be stopped before the die core is changed, and then the drawing machine is restarted after the die core is changed, the die core needs to be disassembled and reassembled during the replacement process. The disassembly and reassembly steps are numerous and take a long time, which leads to longer downtime and reduces the efficiency of drawing thick copper wires. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a drawing die based on a coarse copper wire drawing machine, which solves the problem that the die core needs to be disassembled and reassembled during replacement, resulting in multiple disassembly and reassembly steps, long disassembly and reassembly times, and thus increased downtime, thereby reducing the efficiency of coarse copper wire drawing.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire drawing die based on a coarse copper wire drawing machine, comprising a template, a support column fixedly connected to the side wall of the template, and an installation structure disposed below the support column; two sets of moving structures are provided, both disposed outside the template; and a disassembly and assembly structure is disposed outside the moving structures; wherein, the wire drawing die is installed onto the wire drawing machine as a whole through the installation structure, the internal components of the die are quickly replaced through the moving structure, and the internal components of the die are quickly disassembled and assembled through the disassembly and assembly structure.
[0006] Preferably, the movable structure includes a connecting plate disposed on the front side of the template; two mold cores, both disposed inside the connecting plate; through holes formed on the surface of the mold cores; two connecting ears, respectively fixed to both sides of the connecting plate; threaded holes formed on the front side of the template; wing bolts threadedly connected to the inner walls of the connecting ears and the inner walls of the threaded holes; two sets of limiting parts are provided, respectively disposed between the template and the connecting plate; wherein, rotating the wing bolts out of the threaded holes causes the mold cores to move under the drive of the connecting plate, thereby replacing the mold cores.
[0007] Preferably, the limiting part includes a groove, which is formed on the surface of the template; a protrusion is fixed to the back of the connecting plate, and its outer wall is slidably connected to the inner wall of the groove; wherein, the connecting plate is limited by the cooperation of the groove and the protrusion.
[0008] Preferably, the disassembly and assembly structure includes a horizontal column hinged to the outer wall of the connecting plate; a first recess fixed to the side wall of the connecting plate; a second recess fixed to the end of the horizontal column; a screw rotatably connected to the outer wall of the first recess via a pin; a threaded cap threadedly connected to the outer wall of the screw; and an auxiliary part disposed between the connecting plate and the mold core. The threaded cap is rotated off the screw, thereby causing the horizontal column to flip, allowing for the disassembly and assembly of the mold core.
[0009] Preferably, the auxiliary part includes an insertion hole, which is formed on the inner wall of the connecting plate; the insertion block is fixed to the outer wall of the mold core, and the outer wall is inserted into the inner wall of the insertion hole; wherein the mold core is limited by the insertion hole and the insertion block.
[0010] Preferably, the mounting structure includes a crossbeam fixed to the outer wall of the support column; a mounting plate fixed to the bottom of the support column; and mounting holes formed on the surface of the mounting plate; wherein, the mold is mounted onto the wire drawing machine by means of the cooperation between the mounting plate and the mounting holes.
[0011] Preferably, a reinforcing rib is fixed between the support column and the mounting plate. Beneficial effects
[0012] This utility model provides a wire drawing die based on a coarse copper wire drawing machine. It has the following advantages: This wire drawing die, based on a coarse copper wire drawing machine, achieves rapid replacement of the die core through the cooperation of a connecting plate, die core, through hole, connecting ear, wing bolt, threaded hole, and limiting part. This solves the problem that the die core needs to be disassembled and reassembled during replacement, resulting in multiple disassembly and reassembly steps, long disassembly and reassembly times, and thus increased downtime, thereby reducing the efficiency of coarse copper wire drawing.
[0013] By coordinating the horizontal column, the first concave block, the second concave block, the screw, the threaded cap, and the auxiliary parts, the mold core can be quickly disassembled and assembled. This solves the problem that when workers rotate the mounting bolts to disassemble and assemble the mold core, they need to use external tools during the disassembly and assembly process. If the tools are not complete or the specifications are not compatible, the disassembly and assembly process will be interrupted, forcing workers to stop operating to find suitable tools, which will further prolong the mold core disassembly and assembly time.

Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] This results in the need to disassemble and reassemble the mold core during replacement, which involves multiple steps and takes a long time, leading to longer downtime and reduced efficiency in drawing thick copper wire.
[0018] In view of this, the present invention provides a drawing die based on a coarse copper wire drawing machine. Through the cooperation of the connecting plate, die core, through hole, connecting ear, wing bolt, threaded hole and limiting part, the die core can be quickly replaced. This solves the problem that the die core needs to be disassembled and assembled during the replacement process, which involves many disassembly and assembly steps and takes a long time, resulting in longer downtime and reduced efficiency of coarse copper wire drawing.
[0019] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0020] Example 1: By Figure 1-4 It is known that a wire drawing die based on a coarse copper wire drawing machine includes a template 1, with a support column 2 fixedly connected to the side wall of the template 1. The wire drawing die based on the coarse copper wire drawing machine also includes an installation structure 4, a moving structure 5, and a disassembly and assembly structure 6. The installation structure 4 is located below the support column 2; two sets of moving structures 5 are provided, both located outside the template 1; and the disassembly and assembly structure 6 is located outside the moving structures 5. The wire drawing die is installed onto the wire drawing machine as a whole through the installation structure 4, the internal components of the die are quickly replaced through the moving structure 5, and the internal components of the die are quickly disassembled and assembled through the disassembly and assembly structure 6. In the specific implementation process, it is worth noting that the support column 2 is supported by the rainproof template 1, and the support column 2 and the template 1 can be connected by screws. The wire drawing die is installed onto the wire drawing machine by the installation structure 4. The internal components of the die can be quickly replaced by the moving structure 5, and the internal components of the die can be quickly disassembled and assembled by the disassembly and assembly structure 6.
[0021] Example 2: From Figure 1-4 As can be seen, the movable structure 5 includes a connecting plate 51, a mold core 52, a through hole 53, a connecting lug 54, a wing bolt 55, a threaded hole 56, and a limiting part 57. The connecting plate 51 is disposed on the front side of the template 1; there are two mold cores 52, both disposed inside the connecting plate 51; the through holes 53 are all opened on the surface of the mold core 52; there are two connecting lugs 54, which are respectively fixed to both sides of the connecting plate 51; the threaded hole 56 is opened on the front side of the template 1; the wing bolt 55 is threadedly connected to the inner wall of the connecting lug 54 and the inner wall of the threaded hole 56 respectively; there are two sets of limiting parts 57, which are respectively disposed between the template 1 and the connecting plate 51; wherein, by rotating the wing bolt 55 out of the threaded hole 56, the mold core 52 is moved under the drive of the connecting plate 51, thereby replacing the mold core 52; In the specific implementation process, it is worth noting that when drawing thick copper wire, the workers will install the mold core 52 that needs to be used on the connecting plate 51. After that, the workers will thread the copper wire into the through hole 53, then thread the copper wire out of the template 1, and finally fix it on the drawing machine. The drawing machine will be started so that the copper wire moves in the through hole 53 to perform the drawing process. When it is necessary to change the mold core 52 of different diameters, the operator first rotates the wing bolt 55, which moves the wing bolt 55 out of the threaded hole 56, thus loosening the connecting plate 51 from the template 1. Then, the operator moves the connecting plate 51, which moves on the template 1 and drives the mold core 52 to move. The middle mold core 52 is moved to the top of the template 1, and the lower mold core 52 is moved to the middle position of the template 1. Finally, the operator rotates the wing bolt 55 in the opposite direction, which rotates the wing bolt 55 into the corresponding threaded hole 56, fixing the connecting plate 51 and thus fixing the mold core 52 to be used, enabling quick replacement of the mold core 52. Furthermore, the limiting part 57 includes a groove 571 and a protrusion 572. The groove 571 is formed on the surface of the template 1; the protrusion 572 is fixed to the back of the connecting plate 51, and its outer wall is slidably connected to the inner wall of the groove 571; wherein, the connecting plate 51 is limited by the cooperation of the groove 571 and the protrusion 572. In the specific implementation process, it is worth noting that when the connecting plate 51 moves, the connecting plate 51 drives the protrusion 572 to move. The protrusion 572 moves in the slide groove 571 to limit the connecting plate 51, so as to ensure the straightness and positional accuracy of the connecting plate 51 during the movement and prevent it from deviating. Furthermore, the disassembly and assembly structure 6 includes a horizontal column 61, a first recess 62, a second recess 63, a screw 64, a threaded cap 65, and an auxiliary part 66. The horizontal column 61 is hinged to the outer wall of the connecting plate 51; the first recess 62 is fixed to the side wall of the connecting plate 51; the second recess 63 is fixed to the end of the horizontal column 61; the screw 64 is rotatably connected to the outer wall of the first recess 62 via a pin; the threaded cap 65 is threadedly connected to the outer wall of the screw 64; the auxiliary part 66 is disposed between the connecting plate 51 and the mold core 52; wherein, by rotating the threaded cap 65 off the screw 64, the horizontal column 61 is flipped over, allowing the mold core 52 to be disassembled and assembled. In the specific implementation process, it is worth noting that when disassembling and assembling the mold core 52, the worker first rotates the threaded cap 65, which rotates out of the screw 64. Then, the worker rotates the screw 64, causing it to leave the second recess 63 and release the fixation of the cross post 61. The worker then rotates the cross post 61 to place the mold core 52 into the connecting plate 51. After that, the worker rotates the cross post 61 again, causing it to contact the mold core 52. The cross post 61 drives the second recess 63 to move, thereby making the second recess 63 and the first recess 62 fit together. The worker then rotates the screw 64 again, rotating it into the second recess 63. The threaded cap 65 is then rotated back onto the screw 64 to fix the cross post 61, thus fixing the mold core 52 and enabling quick disassembly and assembly of the mold core 52. Furthermore, the auxiliary part 66 includes a socket 661 and a plug 662. The socket 661 is formed on the inner wall of the connecting plate 51; the plug 662 is fixed to the outer wall of the mold core 52, and the outer wall is inserted into the inner wall of the socket 661; wherein the mold core 52 is limited by the socket 661 and the plug 662. In the specific implementation process, it is worth noting that when the mold core 52 is installed into the connecting plate 51, the mold core 52 drives the insert block 662 to move and insert the insert block 662 into the insertion hole 661, so that the mold core 52 plays a role in initial positioning and limiting during installation, and the mold core 52 can be installed onto the connecting plate 51 quickly and accurately. Furthermore, the mounting structure 4 includes a crossbeam 41, a mounting plate 42, and a mounting hole 43. The crossbeam 41 is fixed to the outer wall of the support column 2; the mounting plate 42 is fixed to the bottom of the support column 2; and the mounting hole 43 is formed on the surface of the mounting plate 42. The mold is installed onto the wire drawing machine by the cooperation of the mounting plate 42 and the mounting hole 43. In the specific implementation process, it is worth noting that the specific specifications and shape of the mounting hole 43 need to be designed according to the appropriate wire drawing machine. This embodiment only provides a schematic diagram. The staff placed the mounting plate 42 on the wire drawing machine. After that, the staff used bolts and other fasteners to pass through the mounting holes 43 on the mounting plate 42 to fix the mold in the appropriate position on the wire drawing machine. The crossbeam 41 serves to connect the support column 2 laterally, which enhances the overall stability of the structure. Furthermore, a reinforcing rib 3 is fixedly connected between the support column 2 and the mounting plate 42; In the specific implementation process, it is worth noting that the main function of the reinforcing rib 3 is to enhance the strength and rigidity of the connection between the support column 2 and the mounting plate 42. When the mold is working, the support column 2 will be subjected to forces from components such as the template 1. The reinforcing rib 3 can effectively disperse these forces, preventing deformation or damage to the connection between the support column 2 and the mounting plate 42, thereby improving the reliability and service life of the entire mold structure.
