Description

Technical Field

[0001] This application relates to the technical field of copper wire processing, and in particular to a copper wire processing technology for improving drawing performance. Background Technology

[0002] Currently, in the traditional copper wire production process, cold drawing is a key process that uses molds to gradually reduce the diameter of the copper wire and improve its precision.

[0003] Existing copper wire processing technologies typically include: single-pass drawing: suitable for copper wires with small deformation (≤20%), which do not require annealing; multi-pass drawing: for copper wires with large deformation (such as drawing from a diameter of 10 mm to 0.5 mm), multiple passes are required.

[0004] However, in pursuit of efficiency, existing processes often only involve a single annealing step during the later stages of drawing or when deformation is extreme. This leads to numerous quality issues with the copper wire, such as accumulated work hardening: during multiple drawing passes, the copper wire undergoes repeated cold deformation, resulting in increased internal dislocation density, significantly increased hardness (e.g., from HV80 to over HV150), and a sharp decrease in plasticity (elongation drops from 30% to below 5%). This causes wire breakage (breakage rate > 3 times / ton) and rapid die wear (die life shortened by 20%-50%) during subsequent drawing. Furthermore, it results in poor dimensional accuracy: due to the high hardness and elasticity of the copper wire, "springback" is common during drawing, leading to diameter deviations exceeding ±0.01mm, failing to meet high precision requirements. Finally, it causes surface quality defects: excessively hard copper wire experiences increased friction with the die during drawing, easily causing scratches, peeling, or surface cracks due to localized stress concentration, affecting the adhesion of subsequent plating / insulation layers. Summary of the Invention

[0005] In order to reduce the quality problems of copper wire, this application provides a copper wire processing technology to improve its drawing performance, which adopts the following technical solution: A copper wire processing technology to improve drawing performance includes the following steps: Step S1, Smelting: Smelting copper raw materials to form copper rods; Step S2, Coarse drawing: Drawing the copper rods to form coarse drawn wires; Step S3, Intermediate drawing: Drawing the coarse drawn wires to form intermediate drawn wires; Step S4, Fine wire semi-finished product: Drawing the intermediate drawn wires to form semi-finished copper wires; Step S5, Intermediate annealing: Annealing the semi-finished copper wires at a heating temperature range of 200-550℃. For continuous annealing, the holding time ranges from 1 to 15 seconds; for box annealing, the holding time ranges from 1 to 2 hours. After annealing, the wire is first cooled with annealing liquid, then cooled with inert gas, and then dried at 220°C using a drying device to avoid internal stress caused by rapid cooling. Step S6: Wire stretching: Stretch the annealed semi-finished copper wire into finished copper wire. Step S7: Annealing: Anneal the finished copper wire. Step S8: Winding: Wind the finished copper wire using a winding device. Step S9: Finished product inspection.

[0006] By adopting the above technical solution, intermediate annealing can improve the performance stability of the finished copper wire, as well as its elongation and breaking strength, thereby reducing the quality problems of the copper wire.

[0007] Optionally, the winding device includes a base, a vertical plate mounted on the top of the base, a winding rod rotatably mounted on the top of the vertical plate, and a winding motor mounted on one side of the vertical plate; one end of the winding rod is mounted on the output shaft of the winding motor, a winding cylinder for winding finished copper wire is sleeved on the winding rod, and a fixing mechanism for fixing the winding cylinder is mounted on the winding rod.

[0008] By adopting the above technical solution, the winding rod facilitates the installation of the winding cylinder; the fixing mechanism facilitates the limiting of the winding cylinder.

[0009] Optionally, the fixing mechanism includes a fixing ring fixed to the side wall of the winding rod, an installation groove opened in the winding rod, a first cylinder installed in the installation groove, and an abutment plate fixed to the piston rod of the first cylinder; the abutment plate abuts against the side of the winding cylinder away from the fixing ring; the abutment plate has a first through hole, an installation block is fixedly connected in the first through hole, a moving rod is slidably connected to the installation block, a first spring is sleeved on the moving rod, a clamping block and a limit nut are respectively fixed to the two ends of the moving rod, the two ends of the first spring abut against the opposite inner sides of the installation block and the clamping block, and a spherical surface is provided at the end of the clamping block away from the first spring, the spherical surface matching the side of the winding cylinder away from the fixing ring.

[0010] By adopting the above technical solution, when it is necessary to limit the end of the winding cylinder away from the fixing ring, the first cylinder is first activated. At this time, the piston rod of the first cylinder drives the abutment plate to move out of the mounting groove. The movement of the abutment plate out of the mounting groove can limit the end of the winding cylinder away from the fixing ring. When the abutment plate moves out of the mounting groove, the clamping block moves into the first through hole under the action of the spherical surface. The movement of the clamping block into the first through hole presses against the first spring. When the abutment plate is in place, the clamping block clamps the end of the winding cylinder away from the fixing ring under the action of the first spring. In summary, the fixing mechanism facilitates the fixing of the winding cylinder.

[0011] Optionally, a pushing mechanism for driving the winding cylinder to move away from the vertical plate is installed on the vertical plate. The pushing mechanism includes a forward and reverse motor installed on the side wall of the vertical plate, a first lead screw fixed to the output shaft of the forward and reverse motor, and a first guide rod fixed to the side wall of the vertical plate. A first sliding sleeve is threaded onto the first lead screw, and the first sliding sleeve is slidably connected to the first guide rod. A rack is fixed to the side of the first sliding sleeve near the vertical plate, and a push ring is fixed to the end of the rack away from the first sliding sleeve. The push ring is sleeved on the winding rod and can abut against the side of the winding cylinder near the vertical plate.

[0012] By adopting the above technical solution, when it is necessary to push out the winding cylinder, the first cylinder is first activated. At this time, the piston rod of the first cylinder pulls the abutment plate into the mounting groove. At this time, the end of the winding cylinder away from the first limiting plate is released from the limit. Then, the forward and reverse motor is activated. At this time, the output shaft of the forward and reverse motor drives the first lead screw to rotate. The rotation of the first lead screw drives the first sliding sleeve to move towards the vertical plate. The movement of the first sliding sleeve towards the vertical plate drives the rack to move away from the vertical plate. The movement of the rack away from the vertical plate drives the push ring to move away from the vertical plate. The movement of the push ring away from the vertical plate pushes out the winding cylinder. In summary, the push mechanism facilitates the pushing out of the winding cylinder.

[0013] Optionally, the base is equipped with a receiving mechanism for receiving the winding cylinder. The receiving mechanism includes two second guide rods fixed to the top of the base, two second sliding sleeves that are slidably connected to the two second guide rods, and a receiving plate installed on the two second sliding sleeves. A tray is installed on the top of the receiving plate, and a transmission mechanism for driving the receiving plate to move is installed on the base.

[0014] By adopting the above technical solution, when the push ring pushes out the winding cylinder, the transmission mechanism drives the receiving plate to move upward, and the upward movement of the receiving plate drives the tray to move upward, thereby receiving the winding cylinder; in summary, the set receiving mechanism facilitates the receiving of the winding cylinder.

[0015] Optionally, the transmission mechanism includes a second lead screw rotatably connected to the side wall of the vertical plate, a gear sleeved and fixed to the side wall of the second lead screw, a vertical rod fixed to the side wall of the vertical plate, and a movable plate threaded to the second lead screw; the movable plate is slidably connected to the vertical rod, and the gear meshes with a rack; a third guide rod is fixedly connected to the base, a third sliding sleeve is slidably connected to the third guide rod, a first push rod is hinged between the movable plate and the third sliding sleeve, and a second push rod is hinged between the third sliding sleeve and the receiving plate.

[0016] By adopting the above technical solution, when the rack moves away from the vertical plate, it drives the gear. The gear rotation drives the second lead screw to rotate, and the second lead screw rotation drives the moving plate to move downward. Then, the first push rod, under the action of the moving plate, pushes the third sliding sleeve to move. Next, the third sliding sleeve, under the action of the second push rod, drives the receiving plate to move upward, thus driving the receiving plate to move upward. When it is necessary to reset the receiving plate to lower the center of gravity of the winding cylinder, the first lead screw is first driven to rotate in the opposite direction by the forward and reverse motor. The reverse rotation of the first lead screw drives the gear to rotate in the opposite direction, and the reverse rotation of the gear drives the second lead screw to rotate in the opposite direction. The reverse rotation of the second lead screw drives the moving plate to move upward. Then, the first push rod, under the action of the moving plate, pushes the third sliding sleeve to move in the opposite direction. Next, the third sliding sleeve, under the action of the second push rod, drives the receiving plate to move downward, thus driving the receiving plate to reset. In summary, the transmission mechanism is designed to facilitate the movement of the receiving plate.

[0017] Optionally, a plurality of first insert plates are fixedly connected to the bottom of the tray, and a plurality of first slots are provided on the top of the receiving plate, with the plurality of first insert plates inserted into the plurality of first slots.

[0018] By adopting the above technical solution, the first insert plate and the first slot are designed to facilitate the positioning of the tray.

[0019] Optionally, barrier railings are fixed to both sides of the receiving plate.

[0020] By adopting the above technical solution, the installed barrier can reduce the possibility of the winding drum rolling off the receiving plate.

[0021] Optionally, a support mechanism for supporting the receiving plate is installed between the two second guide rods. The support mechanism includes a connecting plate installed between the two second guide rods, multiple second through holes opened on the side wall of the connecting plate, multiple second insert plates slidably connected to the multiple second through holes, and multiple second slots opened on the side of the receiving plate near the connecting plate. The bottom of the second insert plate is provided with an inclined surface, which matches the side of the receiving plate near the connecting plate. The multiple second insert plates are inserted into the multiple second slots in a corresponding manner. A fourth sliding sleeve is fixedly connected to the side wall of the second insert plate. A fourth guide rod is fixedly connected to the side of the connecting plate away from the receiving plate. The fourth sliding sleeve is slidably connected to the fourth guide rod. A second spring is fixedly connected between the fourth sliding sleeve and the connecting plate. An intermediate plate is fixedly connected between the fourth sliding sleeves. A pushing component for driving the intermediate plate to move away from the second slot is installed on the side of the connecting plate away from the receiving plate.

[0022] By adopting the above technical solution, when the receiving plate moves upward, it drives the second insert plate to move into the second through hole under the action of the inclined plane. The movement of the second insert plate into the second through hole drives the fourth sliding sleeve to move, and the movement of the fourth sliding sleeve applies force to the second spring. When the receiving plate moves to align the second insert plate with the second slot, the fourth sliding sleeve drives the second insert plate to insert into the second slot under the action of the second spring, thereby supporting the receiving plate. In summary, the set support mechanism facilitates the support of the receiving plate.

[0023] Optionally, the pushing assembly includes a second cylinder mounted on the side of the connecting plate away from the receiving plate and a push plate fixed to the piston rod of the second cylinder; the push plate can abut against the side of the intermediate plate near the connecting plate.

[0024] By adopting the above technical solution, when it is necessary to separate the second insert plate from the second slot, the second cylinder is first activated. At this time, the piston rod of the second cylinder drives the push plate to move away from the second slot. The movement of the push plate away from the second slot drives the intermediate plate to move away from the second slot. The movement of the intermediate plate away from the second slot drives the fourth sliding sleeve to move away from the second slot. The movement of the fourth sliding sleeve away from the second slot causes the second insert plate to move away from the second slot, thereby separating the second insert plate from the second slot. In summary, the push assembly facilitates the separation of the second insert plate from the second slot.

[0025] In summary, this application includes at least one of the following beneficial technical effects: Intermediate annealing can improve the performance stability of finished copper wire, as well as its elongation and breaking strength, thus reducing quality problems in the copper wire.
