Description

Technical Field

[0001] This invention relates to the field of wire drawing machine technology, and in particular to an automatic polishing and wire drawing machine for metal wire. Background Technology

[0002] An automatic polishing and drawing machine for metal wire is a device specifically designed to change the size and shape of metal wire by stretching it, while simultaneously polishing the surface of the metal wire. The working principle of this equipment is to stretch the metal wire to a finer diameter through the wire drawing process, while removing surface unevenness or defects, so that the wire reaches the required specifications and has a better surface quality. During the stretching process, the metal wire often passes through different drawing dies to gradually reduce its diameter and increase the smoothness of the surface, ultimately forming a fine metal wire that meets the requirements.

[0003] Existing metal wire polishing and drawing machines generally adopt single-segment drawing, that is, the stretching and surface treatment of metal wire are completed in a continuous process. Although this method can achieve the required dimensions and surface treatment of metal wire, it is prone to some quality problems. Especially in the processing of metal wires such as copper wire, single-segment drawing is prone to surface cracks. Especially in more fragile materials or when the tensile force is too large during the stretching process, cracks and deformation problems are particularly prominent, affecting the performance and appearance quality of the wire.

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] Example 1, as Figure 1 and Figure 2 As shown, an automatic polishing and drawing machine for metal wire includes a base 1. Two symmetrically distributed guard plates 2 are fixedly connected to the front and rear sides of the upper end of the base 1. Triangular trusses 3 are fixedly connected to the lower left ends of the two left guard plates 2. Motors 4 are fixedly connected to the upper ends of the two triangular trusses 3. Winding rollers 5 are rotatably connected to the upper parts of the ends of the two front guard plates 2 and the two rear guard plates 2 that are close to each other. The output ends of motors 4 on the same side pass through the guard plates 2 on the same side and are fixedly connected to the winding rollers 5 on the same side via couplings. A primary wire drawing assembly is fixedly installed on the front side of the middle of the upper end of the base 1. 6. A final section wire drawing component 7 is fixedly installed at the middle of the upper end of the base 1. The initial section wire drawing component 6 can clamp and pull the copper wire during the wire drawing process to perform preliminary wire drawing. During the preliminary wire drawing, a margin is reserved for subsequent wire drawing, thereby avoiding cracks on the surface of the copper wire during single wire drawing. At the same time, the initial section wire drawing component 6 can also place the preliminarily drawn copper wire into the final section wire drawing component 7 for secondary wire drawing. The secondary wire drawing using the final section wire drawing component 7 can correct the surface of the copper wire drawn in the first drawing, thereby improving the processing accuracy of the copper wire during wire drawing. A segmented drive assembly 8 is fixedly installed at the middle of the rear side of the upper end of the base 1. The segmented drive assembly 8 can provide multiple strokes for the initial wire drawing assembly 6 and the final wire drawing assembly 7, so that the initial wire drawing assembly 6 and the final wire drawing assembly 7 do not interfere with each other when drawing copper wire, thus improving the smoothness of the overall wire drawing process.

[0019] The two winding rollers 5 mentioned above are conventional settings in the prior art. In this solution, it is only necessary to ensure that the copper wire to be drawn is wound around its outer surface and that it is easy to disassemble and remove later. At the same time, it is necessary to ensure that the two winding rollers 5 are fixedly connected to the output end of the motor 4 on the same side so as to facilitate subsequent processing and driving. Therefore, the two winding rollers 5 are conventional designs in the prior art, and their specific installation and disassembly methods are also conventional designs in the prior art. The specific disassembly method can be adjusted according to actual production needs, and this solution will not elaborate on it in detail.

[0020] Example 2: Based on Example 1, this example aims to perform preliminary wire drawing on copper wire and simultaneously insert the wire into the final wire drawing assembly 7 for secondary wire drawing.

[0021] For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The initial drawing assembly 6 includes a drawing plate 61 fixedly connected to the front side of the middle of the upper part of the base 1. A rectangular hole 62 is provided on the left and right sides of the middle of the front end of the drawing plate 61, penetrating the rear end of the drawing plate 61. A concave plate 63 is provided on the rear side of the drawing plate 61. The lower end of the concave plate 63 is slidably connected to the upper end of the base 1. A top plate 64 is fixedly connected to the middle of the left and right ends of the concave plate 63. A sliding hole 65 is provided on the middle of the rear end of the two top plates 64, penetrating the front end of the top plate 64 on the same side. A C-shaped plate 66 is fixedly connected to the left side of the upper end of the concave plate 63. A motor 67 is fixedly connected to the top wall of the C-shaped plate 66. A wire feeding assembly 68 is slidably installed on the left and right sides of the inner surface of the concave plate 63. A wire outlet 60 is provided on the upper part of the front end of the drawing plate 61, penetrating its rear end.

[0022] Furthermore, the wire feeding assembly 68 includes two rectangular plates 681. The left and right ends of the two rectangular plates 681 are slidably connected to the left and right walls of the inner surface of the concave plate 63. The left and right sides of the ends of the two rectangular plates 681 that are close to each other are provided with threaded holes penetrating the outer sides. The inner surfaces of the two threaded holes on the left and the two threaded holes on the right are all threadedly connected to threaded rods 682. Pulleys 683 are fixedly connected to the upper part of the outer surfaces of the two threaded rods 682. A belt 684 is wound around the outer surfaces of the two pulleys 683. Two rectangular plates 681 are fixedly connected to the middle of their respective ends with a semi-circular plate 685. The inner arc surfaces of the two semi-circular plates 685 are fixedly connected to the inner arc surfaces of their respective ends with an arc-shaped clamping plate 686. The outer arc surfaces of the two arc-shaped clamping plates 686 are each provided with an arc-shaped groove 687. The inner arc surfaces of the two arc-shaped grooves 687 are slidably connected to an arc-shaped guide plate 688. Several springs 689 are fixedly connected in a circular array at the respective ends of the arc-shaped guide plate 688 and the arc-shaped groove 687 on the same side. The upper end of the threaded rod 682 on the left side is fixedly connected to the output end of the motor 67 via a coupling.

[0023] Furthermore, the rear ends of both arc-shaped guide plates 688 are inclined, and the wire outlet 60 is located between the two arc-shaped clamping plates 686.

[0024] Furthermore, the final wire drawing assembly 7 includes a wire drawing plate 71 fixedly connected to the middle of the upper end of the base 1. A block placement hole 72 is provided at the lower center of the front end of the wire drawing plate 71, extending through its rear end. A concave plate 73 is provided on the rear side of the wire drawing plate 71. The lower end of the concave plate 73 is slidably connected to the upper end of the base 1. A C-shaped plate 74 is fixedly connected to the right side of the upper end of the concave plate 73. A motor 75 is fixedly connected to the top wall of the C-shaped plate 74. Two rectangular plates 76 are slidably connected to the left and right walls of the inner surface of the concave plate 73. The left and right sides of the two rectangular plates 76 that are close to each other are... A threaded hole 2 is provided through the outer side. The inner surfaces of the two threaded holes 2 on the left and the two threaded holes 2 on the right are all threadedly connected to a threaded rod 2 77. The upper part of the outer surface of the two threaded rods 2 77 is fixedly connected to a pulley 2 78. The outer surface of the two pulleys 2 78 is wound with a belt 2 79. The upper end of the threaded rod 2 77 on the right is fixedly connected to the output end of the motor 3 75 through a coupling. The middle of the two rectangular plates 2 76 that are close to each other is fixedly connected to a semi-circular plate 2 70. The inner arc surface of the two semi-circular plates 2 70 that are close to each other is fixedly connected to an arc-shaped wire clamping block 701.

[0025] Furthermore, the wire drawing plate 71 has a wire outlet 702 extending through its rear end at the upper middle part of its front end. The wire outlet 702 is located between two arc-shaped wire clamping blocks 701.

[0026] When preliminary wire drawing is required, a section of copper wire installed on the surface of the front winding roller 5 can be manually pulled out. Then, the pulled-out section is inserted from the front end of the wire outlet 60 to the rear end of the wire outlet 60, and the end of this section of copper wire is aligned with the rear end of the two arc-shaped guide plates 688 or extended by a small section. Then, by starting the motor 67, its output end can drive the threaded rod 682 fixedly connected to it to rotate. The outer surfaces of the pulleys 683 fixedly connected to the upper part of the outer surfaces of the two threaded rods 682 are wrapped with belt 684. Therefore, under the transmission connection of belt 684, the two threaded rods 682 can rotate simultaneously. Since the left and right sides of the two rectangular plates 681 that are close to each other are provided with threaded holes that penetrate the outer side, and the inner surfaces of the two threaded holes on the left and the two threaded holes on the right are threadedly connected to the threaded rods 682 on the same side, when the two threaded rods 682 rotate, the two rectangular plates 681 can move inward simultaneously under the limiting and guiding action of the left and right side walls of the inner surface of the concave plate 63. When the two rectangular plates 681 move inward at the same time, the semicircular plate 685, which is fixedly connected to the middle of their adjacent ends, moves inward, causing the arc-shaped clamping plate 686, which is fixedly connected to the inner arc surface of the two semicircular plates 685, to move inward and clamp the copper wire. When the concave plate 63 moves backward, it can simultaneously drive the rectangular plate 681 to move backward, and the two arc-shaped clamping plates 686 can clamp the copper wire and then pull it, thereby continuously pulling the copper wire through the wire outlet 60 to the surface of the winding roller 5 for preliminary wire drawing processing. When the rectangular plate 681 moves backward until the arc-shaped guide plate 688 contacts the wire outlet 702 opened in the middle of the upper side of the front end of the wire drawing plate 71, since the inner cavity of the wire outlet 702 is gradually narrowed from front to back, when the arc-shaped guide plate 688 contacts the inner surface of the wire outlet 702, it will only abut against the front side of the inner surface of the wire outlet 702. Then the two arc-shaped guide plates 688 are squeezed and contracted in the arc-shaped groove 687 on the same side, and simultaneously squeeze the spring 689 on the same side. During this process, the two arc-shaped clamping plates 686 can feed the copper wire clamped in their inner cavity into the wire outlet 702. Meanwhile, the two arc-shaped guide plates 688 can also limit and guide the copper wire to avoid large bending of the copper wire when it is inserted into the wire outlet 702; After the copper wire is fed into the wire outlet 702, it can be flipped by starting the output end of the motor 67. Then the semicircular plate 685 opens. Since the rear ends of the two arc-shaped guide plates 688 are inclined, when the two arc-shaped guide plates 688 open with the semicircular plate 685 on the same side, the inclined setting will cause the arc-shaped guide plates 688 to be squeezed and contracted, and then further move into the inner cavity of the arc-shaped groove 687, so that the copper wire is no longer clamped. When the copper wire enters the outlet 702, simply start the motor 75. The output of the motor 75 will drive the threaded rod 77, which is fixedly connected to it, to rotate via the coupling. When the two threaded rods 77 rotate, threaded holes 2 are provided on the left and right sides of the two rectangular plates 76 that are close to each other. The inner surfaces of the two threaded holes 2 on the left and the two threaded holes 2 on the right are threadedly connected to the threaded rods 77. The pulleys 7 are fixedly connected to the upper part of the outer surfaces of the two threaded rods 77. 8 are wound together with belt 2 79. Therefore, under the action of belt 2 79, the two threaded rods 2 77 rotate simultaneously. Then, the two rectangular plates 2 76 move inward simultaneously, which causes the two rectangular plates 2 76 to drive the semi-circular plates 2 70 fixedly connected to them to move inward. Finally, the two semi-circular plates 2 70 drive the arc-shaped wire clamping block 701 fixedly connected to their inner arc surface to clamp and fix one end of the copper wire. At this time, after the concave plate 2 73 moves backward a certain distance, the copper wire can be pulled backward a certain distance from the wire outlet 2 702. Then, by starting the C-shaped plate 74, its output end is flipped, the arc-shaped wire clamping block 701 is opened, and the copper wire that has been pulled out for a distance is installed on the outer surface of the winding roller 5 on the rear side. Then, the motor 4 on the rear side is started to continuously wind the wire, so that the wire drawing process can be continuously carried out. By using a two-stage wire drawing process and progressive deformation in stages, the stress of a single process can be effectively reduced, the uniformity of the internal structure of the material can be improved, and the surface finish can be enhanced while reducing the generation of cracks.

[0027] Meanwhile, in order to enable the copper wire to be polished during the second stage of wire drawing, this solution can be achieved by installing abrasive paper on the inner surface of the wire exit 702. The specifications of the abrasive paper can be adjusted according to actual production needs, as long as it meets the requirement of polishing the surface of the copper wire during wire drawing. Therefore, this solution will not elaborate further on it.

[0028] Example 3 is based on Example 2, and aims to achieve the purpose of pushing concave plate 63 and concave plate 73 in stages.

[0029] For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The segmented drive assembly 8 includes a rectangular platform 81 fixedly connected to the middle of the rear side of the upper end of the base 1. A hydraulic cylinder 82 is fixedly connected to the upper end of the rectangular platform 81. A connecting plate 83 is fixedly connected to the output end of the hydraulic cylinder 82 through a piston rod. Push rods 84 are fixedly connected to the left and right sides of the front end of the connecting plate 83. A rectangular block 85 is fixedly connected to the front end of each of the two push rods 84. A spring 86 is fixedly connected to the end of each of the two rectangular blocks 85 and the sliding hole 65 on the same side. The two springs 86 are located on the outside of the two push rods 84 respectively. A protrusion 87 is fixedly connected to the front side of the outer surface of the two push rods 84. A top block 88 is fixedly connected to the rear side of the outer surface of the two push rods 84.

[0030] Furthermore, the protrusion 87 is located behind the two sliding holes 65, and the two top blocks 88 are both located behind the concave plate 73.

[0031] Furthermore, the outer diameters of the two rectangular blocks 85 are the same as the inner diameters of the two rectangular holes 62, the outer diameter of the protrusion 87 is the same as the inner diameter of the block placement hole 72, and both push rods 84 pass through the push rods 84 and the rectangular holes 62.

[0032] To achieve the movement of the concave plate 63 and the concave plate 73 in the above embodiment, the hydraulic cylinder 82 can be activated, so that the output end of the hydraulic cylinder 82 drives the connecting plate 83 fixedly connected to it to move backward through the piston rod. When the connecting plate 83 moves backward, it will first drive the two push rods 84 to move backward. When the two push rods 84 move backward, since the ends of the two rectangular blocks 85 and the sliding holes 65 on the same side are fixedly connected to the same side, and the two springs 86 are located on the outside of the two push rods 84, the springs 86 on both sides can simultaneously push the sliding holes 65 to move backward. The two sliding holes 65 are fixedly connected to the concave plate 63, and the concave plate 63 is slidably connected to the upper end of the base 1, so the concave plate 63 can move backward. When the rear end of the concave plate 63 moves backward to fit against the front end of the wire drawing plate 71, since the outer diameter of the two rectangular blocks 85 is the same as the inner diameter of the two rectangular holes 62, and the outer diameter of the protrusion 87 is the same as the inner diameter of the block placement hole 72, and both push rods 84 pass through the block placement hole 72 and the rectangular hole 62, the rectangular block 85 can pass through the inner cavity of the rectangular hole 62, and the protrusion 87 can enter the inner cavity of the block placement hole 72; When it moves backward, the two top plates 64 will abut against the front end of the second wire drawing plate 71 and stop moving, while the two push rods 84 will continue to slide backward from the sliding hole 65, thereby causing the rectangular block 85 to continuously compress and contract the second spring 86 on the same side. Then the two push rods 84 continue to drive the protrusion 87 fixedly connected to its outer surface to move backward, and cause the protrusion 87 to push the second concave plate 73 to slide backward at the upper end of the base 1. When it is necessary to push the concave plate 2 73 and the concave plate 1 63 back to their initial positions, the two top blocks 88 will push the concave plate 2 73 forward. After releasing the compressive force, the two springs 2 86 can pull the sliding hole 65, so that the two sliding holes 65 drive the concave plate 1 63 forward.

[0033] It should be noted that the specific installation methods, circuit connection methods, and control methods of the two motors 4, 67, C-shaped plate 74, and hydraulic cylinder 82 used in this invention are all conventional designs, and will not be described in detail in this invention.
