Abstract
Description
Technical Field
[0001] This utility model relates to a wire drawing machine, and more particularly to a copper wire annealing mechanism for a wire drawing machine. Background Technology
[0002] To improve the efficiency of copper wire drawing, some wire drawing machines currently perform electro-annealing on the copper wire during the drawing process. This softens the copper wire after being energized, thereby increasing its elongation during subsequent drawing. Existing annealing mechanisms in wire drawing machines, as shown in patents 200710070375.5 or 201410017336.9, include multiple electrode wheels arranged sequentially along the wire's path. These wheels are energized after the copper wire passes through, allowing for electro-annealing in a short-circuit state. Simultaneously, the copper wire is immersed in a coolant during the electro-annealing process. This prevents oxidation caused by contact with external air during annealing and also cools the wire to prevent high-temperature oxidation after it exits the annealing mechanism.
[0003] However, the existing wire drawing machine annealing mechanism has two problems when filling coolant: firstly, the utilization rate is low, meaning that manufacturers need to inject more coolant to ensure complete immersion of the copper wire; secondly, the coolant level is prone to instability during circulation, which can cause coolant to overflow from the copper wire routing hole, reducing the stability of the wire drawing machine and increasing the difficulty of cleaning.
[0004] Therefore, the existing wire drawing machine annealing mechanism has the problem of poor coolant filling effect. Utility Model Content
[0005] The purpose of this invention is to provide a copper wire annealing mechanism for a wire drawing machine. It improves the utilization rate of coolant and prevents coolant overflow during use.
[0006] The technical solution of this utility model: A copper wire annealing mechanism for a wire drawing machine includes a wire drawing frame, on which a first wire feeding wheel, a second wire feeding wheel, a first electrode wheel, and an annealing plate are respectively provided. An annealing door is hinged to one side of the annealing plate. A groove is provided on one side of both the annealing plate and the annealing door. The two grooves form an annealing chamber after they are closed together. A liquid accumulation area is formed at the bottom of the annealing chamber. A liquid outlet is provided on one side of the liquid accumulation area. A second electrode wheel is provided in the liquid accumulation area. An inlet area and an outlet area are respectively provided on both sides of the annealing chamber, which are connected to the liquid accumulation area. An inlet pipe and an outlet pipe are respectively provided in the inlet area and the outlet area. An inlet port is provided at the upper end of the inlet pipe. A drying area located in the annealing chamber is provided on the side of the outlet area away from the liquid accumulation area. An overflow port is provided on one side of the drying area. A cleaning plug is detachably connected in the drying area.
[0007] In the aforementioned copper wire annealing mechanism for wire drawing machine, a water outlet valve is fixedly connected to the annealing plate outside the liquid outlet, and a coolant tank is provided on the wire drawing machine frame below the water outlet valve.
[0008] In the aforementioned copper wire annealing mechanism for a wire drawing machine, an overflow pipe connected to the annealing plate is provided outside the overflow port, and the overflow pipe extends along the outer wall of the annealing plate to the top of the coolant tank.
[0009] In the aforementioned copper wire annealing mechanism for a wire drawing machine, water passage holes are provided at both ends of the outlet tube, and a liquid level pipe is connected to the annealing gate. The two ends of the liquid level pipe are respectively connected to the water passage holes at both ends of the outlet tube.
[0010] In the aforementioned copper wire annealing mechanism for a wire drawing machine, the cleaning plug includes a sleeve, both ends of which are threaded with cover plates. The cover plates have a round hole in the middle for the copper wire to pass through. The sleeve is filled with a cleaning part, and the inner side of the cover plates has a pressing part that matches the cleaning part.
[0011] In the aforementioned copper wire annealing mechanism for wire drawing machines, the cleaning part is in the shape of a thin sheet and is wound into shape inside a sleeve. The extrusion part consists of multiple oblique pieces arranged in a ring. The extrusion part is used to apply an inwardly inclined extrusion force to the end of the cleaning part after the cover plate is screwed in, so that the cleaning part deforms inward and fits the copper wire after extrusion.
[0012] Compared with the prior art, this utility model has the following characteristics:
[0013] (1) By limiting the structure of the annealing chamber, this utility model can effectively reduce the space occupied by the annealing chamber while achieving the copper wire immersion effect, thereby reducing the amount of coolant used; by cooperating with the outlet valve, overflow pipe and liquid level pipe, the operator can adjust the water output of the outlet valve according to the liquid level in the annealing chamber during use, so that the coolant can quickly fill the annealing chamber after injection, and facilitate the manufacturer to control the liquid level in the annealing chamber; when the coolant in the annealing chamber reaches the threshold, the coolant can also be discharged out through the overflow port and returned to the coolant tank through the overflow pipe, thereby effectively preventing the coolant from overflowing;
[0014] (2) By limiting the structure of the cleaning plug, on the one hand, the sleeve and cover plate can be used to shield the cleaning part, preventing the coolant in the annealing chamber from contacting the cleaning part after overflowing and causing the cleaning part to get wet. At the same time, it is convenient for operators to replace the cleaning part. On the other hand, after the cover plates at both ends are screwed in, they can also apply inward squeezing force to the cleaning part through the squeezing part, so that the cleaning part is in close contact with the copper wire under the squeezing force, thereby improving the wiping and drying effect of the cleaning part on the copper wire.
[0015] (3) Through the connection structure of the annealing plate and the annealing door, the operator can also open the annealing door and complete the operation of each component in the annealing chamber, thereby improving the operator's ease of operation;
[0016] Therefore, this invention can improve the utilization rate of coolant and prevent coolant from overflowing during use. Attached Figure Description

Detailed Implementation
[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0022] Example. A copper wire annealing mechanism for a wire drawing machine, configured as follows: Figure 1 As shown, the drawing machine includes a wire drawing frame 1, on which a first wire guide wheel 2, a second wire guide wheel 3, a first electrode wheel 4, and an annealing plate 5 are respectively provided. The annealing plate 5 is detachably connected to the wire drawing frame 1. The second wire guide wheel 3 is located inside the annealing plate 5. The first wire guide wheel 2 and the first electrode wheel 4 are both set on the wire drawing frame 1 above the annealing plate 5. The first wire guide wheel 2 is provided with two wire guide grooves side by side. The two wire guide grooves are used to guide and guide copper wires, respectively.
[0023] Annealing plate 5 is hinged to one side with annealing door 6. Both annealing plate 5 and annealing door 6 have grooves on one side. The two grooves enclose each other to form annealing chamber 7. The bottom of annealing chamber 7 forms liquid accumulation area 701. Liquid accumulation area 701 has liquid outlet 702 on one side. Liquid accumulation area 701 has a second electrode wheel 8. The inner end of the first electrode wheel 4 passes through annealing plate 5 and is rotatably connected to wire drawing frame 1. The two sides of annealing chamber 7 are respectively provided with inlet area 703 and outlet area 704 that connect to liquid accumulation area 701. Inlet pipe 9 and outlet pipe 10 are respectively provided in inlet area 703 and outlet area 704. Inlet pipe 9 has liquid inlet 901 at the upper end. On the side of outlet area 704 away from liquid accumulation area 701, there is a drying area 705 located in annealing chamber 7. The side of drying area 705 has overflow port 706. Cleaning plug 11 is detachably connected in drying area 705.
[0024] The outlet 702 is provided with a water outlet valve 12 fixedly connected to the annealing plate 5. The water outlet valve 12 is vertically downward. A coolant tank 13 is provided on the wire drawing frame 1 below the water outlet valve 12. The coolant tank 13 is connected to a circulation pipeline. The coolant in the coolant tank 13 is collected through the circulation pipeline and then pumped back into the annealing chamber 7.
[0025] The liquid inlet 901 is externally connected to a liquid inlet pipe fixed on the annealing door 6, and the external connection of the liquid inlet pipe is a circulation pipeline.
[0026] The overflow port 706 is provided with an overflow pipe 14 connected to the annealing plate 5 on the outside. The overflow pipe 14 extends along the outer wall of the annealing plate 5 to the top of the coolant tank 13.
[0027] The outlet pipe 10 has water passage holes at both ends, and the annealing door 6 is connected to a liquid level pipe 15. The two ends of the liquid level pipe 15 are respectively connected to the water passage holes at both ends of the outlet pipe 10. The liquid level pipe 15 is used to display the liquid level height in the annealing chamber 7.
[0028] The annealing plate 5 and the annealing door 6 are connected to each other via a latch lock on the side away from the hinge. After the latch lock is locked, it squeezes and limits the annealing plate 5 and the annealing door 6, so that the grooves on both sides are completely fitted together to form a closed annealing cavity 7.
[0029] The cleaning plug 11 includes a sleeve 111, both ends of which are threadedly connected to a cover plate 112. The cover plate 112 has a round hole in the middle for copper wires to pass through. The sleeve 111 is filled with a cleaning part 113, and the inner side of the cover plate 112 has a squeezing part 114 that cooperates with the cleaning part 113.
[0030] The cleaning part 113 can be made of felt or sponge and wound into shape inside the sleeve 111. The extrusion part 114 consists of multiple oblique pieces arranged in a ring. The extrusion part 114 is used to apply an inward extrusion force to the end of the cleaning part 113 after the cover plate 112 is screwed in, so that the cleaning part 113 deforms inward and fits the copper wire after extrusion.
[0031] The working principle of this utility model is as follows: During the annealing process, the copper wire passes through the first wire guide wheel 2, the second wire guide wheel 3, the first electrode wheel 4, the second electrode wheel 8 and the first wire guide wheel 2 in sequence. After the copper wire passes through, the first electrode wheel 4 and the second electrode wheel 8 apply a voltage of about 26V to it. The voltage value is adjusted according to the diameter of the copper wire, so that the copper wire forms a short circuit annealing at this position, thereby achieving the annealing effect.
[0032] During the wire routing process, coolant enters through inlet 901 and sequentially fills the accumulation area 701, wire inlet area 703, and wire outlet area 704, keeping the copper wire submerged during annealing. This prevents oxidation caused by contact with external air during annealing and cools the copper wire, preventing oxidation due to excessive temperature after it extends from cleaning plug 11. Operators can observe the coolant level in annealing chamber 7 through level pipe 15 and adjust the water flow rate of outlet valve 12 accordingly to maintain the coolant level within a stable range. When the coolant level in annealing chamber 7 exceeds the range, it can be discharged through overflow port 706 and overflow pipe 14 and flow back into the coolant tank 13 below, preventing coolant overflow and ensuring the cleaning effect of cleaning plug 11.
[0033] After the copper wire extends from the outlet tube 10, its surface can be wiped by the cooperation of the cleaning plug 11 and the cleaning part 113, thereby removing the coolant residue on the surface of the copper wire. During installation, the cleaning part 113 can be installed in the sleeve 111 by winding, and its two ends are fixed by the cover plate 112. On the one hand, the cover plate 112 shields the cleaning part 113 to prevent the coolant from contacting the cleaning part 113 and wetting it when it overflows. On the other hand, the cooperation of the cover plate 112 and the pressing part 114 presses the ends of the cleaning part 113 inward, so that the cleaning part 113 tightly wraps the copper wire, ensuring its cleaning effect and the stability of the copper wire routing.
