Description

Technical Field

[0001] This invention belongs to the technical field of material processing equipment, and specifically relates to a wire safety annealing device. Background Technology

[0002] In the production of wires and cables, copper wires or other metal conductors purchased externally typically require a series of processing steps to meet product specifications. First, a stretching process is used to thin the copper wire to the required diameter. However, this process generates significant residual stress within the copper wire, severely impacting its mechanical properties and subsequent processing. Therefore, stress-relief annealing is essential to effectively eliminate this residual stress. Annealing not only improves the material's mechanical properties but also enhances the wire's abrasion resistance, fatigue strength, and toughness to a certain extent, thereby ensuring the quality and service life of the wires and cables.

[0003] Traditional hot box annealing devices typically rely on a single heat source, which is insufficient to meet the demands of modern high-quality wire and cable production. Specifically, firstly, due to the reliance on a single heat source, heat tends to concentrate in the upper part of the chamber, resulting in insufficient heating of the lower monofilaments, leading to uneven grain refinement and significant differences in monofilament toughness. Secondly, during the cooling stage, most devices employ direct water cooling or sudden cooling with strong airflow. This method not only causes a sharp increase in metal lattice stress but also reduces cable elongation and easily induces microcracks on the surface, resulting in poor wire quality after annealing. Therefore, it is necessary to design a safe annealing device for wires to address the shortcomings of existing technologies. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, a wire safety annealing device is provided, which improves the quality of the wire after annealing by performing a gradient-decreasing heating annealing process on the copper wire in the wire.

[0005] The technical solution of this invention is: a wire safety annealing device, comprising: a base, which is the load-bearing carrier of the annealing device; a mounting frame, vertically fixedly connected to the top of the base; a placement plate, fixedly installed on the upper side of the mounting frame, the placement plate having a slot for mounting a winding reel, the winding reel being used to load hard copper wire that has undergone a stretching process but has not been annealed; further comprising: guide tubes, three sets of which are evenly spaced and fixedly installed on the mounting frame, each set of guide tubes having multiple tubes; a first heating tube, fixedly connected to one end of the upper guide tube, the first heating tube bending upwards in a "C" shape to the winding reel; a second heating tube, fixedly connected between the upper and middle guide tubes; and a third heating tube, fixedly connected to the middle guide tube. Between the upper and lower guide tubes; induction heating coils, spirally wound around the first, second, and third heating tubes respectively, the first, second, and third heating tubes, together with the guide tubes, form a continuous bending annealing pipe for copper wire; a temperature control module, installed on the first, second, and third heating tubes, the temperature control module is used to monitor the temperature inside the first, second, and third heating tubes and control the corresponding heating coils, the annealing temperature inside the first, second, and third heating tubes decreases sequentially in a certain gradient; a cooling pool, set on the base and used to cool the copper wire extending from the lower guide tube; a conveying mechanism, set on the top of the mounting frame and used to transport the copper wire to be annealed.

[0006] Furthermore, the cooling pool includes a water storage frame fixedly installed on one side of the top of the base. The top of the water storage frame is open and the inside stores water for cooling copper wires. The water storage frame is connected to multiple inlet pipes on the side facing the mounting frame. The inlet pipes are respectively connected to the guide pipes at the bottom. The inside of the water storage frame is a cooling pipe connected to the inlet pipes. The cooling pipe is a pipe with an open upper half and multiple through holes on the bottom wall of the cooling pipe. The water level of the cooling water in the water storage frame is higher than that of the cooling pipe.

[0007] Furthermore, a discharge frame is fixedly installed on the side of the water storage frame away from the inlet pipe, the refrigeration pipe is connected to the discharge frame, and a guide plate is fixedly connected at an inclination inside the discharge frame. The guide plate is inclined downward toward the refrigeration pipe and is used to guide the cooled copper wire inside the refrigeration pipe.

[0008] Furthermore, the conveying mechanism includes two fixed plates symmetrically fixedly connected to the top of the mounting frame. Two sets of roller conveyor belts are symmetrically mounted on the upper and lower sides of the ends of the fixed plates. The upper and lower sets of roller conveyor belts are parallel to each other and can jointly clamp copper wires and drive them forward. A gear is fixedly connected to one of the rollers in the roller conveyor belt. The gears on the upper and lower sets of roller conveyor belts mesh with each other. A first motor is fixedly mounted on one of the fixed plates. The output shaft of the first motor is connected to the roller of one of the roller conveyor belts.

[0009] Furthermore, each of the guide tubes is symmetrically fixedly assembled with a partition block inside its tube wall. The partition block is sealed and separated inside the guide tube. The partition block is used to support the copper wires transmitted inside the guide tube, and at the same time seals and separates the first heating tube, the second heating tube, and the third heating tube.

[0010] Furthermore, support blocks are fixedly installed at the bends of the inner walls of the first, second, and third heating tubes. The support blocks are used to support and guide the copper wires, so that the copper wires can be smoothly transmitted within the first, second, and third heating tubes.

[0011] Furthermore, a guide mechanism is provided on the top of the mounting frame near the conveying mechanism. The guide mechanism uses precision guide copper wires to guide the conveying mechanism. The guide mechanism includes two mounting plates symmetrically and fixedly connected to one side of the top of the mounting frame. A guide rod is fixedly connected between the mounting plates. Multiple guide blocks are slidably connected to the guide rod. A lead screw is rotatably connected between the mounting plates. The lead screw and the guide rod are parallel to each other. A second motor is fixedly mounted on one of the mounting plates. The output shaft of the second motor is connected to the lead screw. The guide blocks are arranged in pairs. The number of threaded segments on the lead screw and the number of guide blocks are the same and they are arranged alternately in opposite directions. Each guide block and the corresponding threaded segment on the lead screw are threadedly engaged.

[0012] Furthermore, the side of the guide block facing the winding reel is an inclined guide plate, which can correctly guide the copper wire.

[0013] The beneficial effects of this invention are: 1. This invention achieves zoned control of the induction heating coil by setting a first heating tube, a second heating tube, and a third heating tube, and cooperating with a temperature control module. This allows the annealing temperature to decrease gradually along the copper wire transmission direction, effectively reducing internal stress concentration caused by rapid temperature changes, improving the uniformity of the copper wire's grain structure, and thus enhancing its wear resistance, fatigue strength, and toughness.

[0014] 2. The present invention adopts a cooling structure that combines a water storage frame and a cooling pipe, so that the copper wire is gradually cooled down, avoiding the problems of increased lattice stress and surface microcracks caused by traditional direct water cooling, and enhancing the cooling efficiency of the copper wire.

[0015] 3. The present invention is equipped with a guiding mechanism, which realizes the synchronous guidance and alignment of multiple sets of copper wires through the linkage of the lead screw and the guide block. Combined with the inclined guide plate design, it is convenient for the copper wires to be automatically fed into the conveying mechanism, saving manual operation and improving work efficiency and accuracy.

[0027] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The technical solutions of the present invention will now be clearly and completely described in conjunction with the accompanying drawings. It should be understood that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] A wire safety annealing device, see Figures 1-5As shown, it includes: a base 1, which is the load-bearing carrier of this annealing device; a mounting frame 2, which is vertically fixed to the top of the base 1; a placement plate 3, which is fixedly installed on the upper side of the mounting frame 2, and the placement plate 3 is provided with a slot for mounting a winding reel 31, which is used to load hard copper wire 100 that has undergone stretching but has not been annealed; it also includes: guide tubes 4, which are provided in three sets and are evenly spaced and fixedly installed on the mounting frame 2, and each set of guide tubes 4 has multiple tubes; a first heating tube 5, which is fixedly connected to one end of the upper guide tube 4, and the first heating tube 5 bends upward in a "C" shape to the winding reel 31; The second heating tube 6 is fixedly connected between the upper and middle guide tubes 4; the third heating tube 7 is fixedly connected between the middle and lower guide tubes 4; the induction heating coil 8 is spirally wound around the first heating tube 5, the second heating tube 6, and the third heating tube 7 respectively. The first heating tube 5, the second heating tube 6, and the third heating tube 7, together with the guide tube 4, form a continuous bending annealing pipe of copper wire 100; the temperature control module 9 is installed on the first heating tube 5, the second heating tube 6, and the third heating tube 7. The temperature control module 9 is used to monitor the internal temperature of the first heating tube 5, the second heating tube 6, and the third heating tube 7 and control the temperature of the tubes. The annealing temperatures of the heating coil, the first heating tube 5, the second heating tube 6, and the third heating tube 7 decrease sequentially in a certain gradient. A cooling pool 11, mounted on the base 1, is used to cool the copper wire 100 extending from the lower guide tube 4. A conveying mechanism 12, located on the top of the mounting frame 2, is used to transport the copper wire 100 to be annealed. Multiple winding reels 31 with the copper wire 100 wound on them are assembled onto the placement plate 3, and then the conveying mechanism 12 transports the copper wire 100 wound on each winding reel 31 into the corresponding first heating tube 5, so that the copper wire 100 passes sequentially through the first heating tube 5, the second heating tube 6, and the third heating tube 7. During annealing, the three heating tubes 7 monitor and control the induction heating coils 8 through the temperature control module 9, so that the annealing high temperature inside the first heating tube 5, the second heating tube 6 and the third heating tube 7 decreases in a gradient. By gradually reducing the temperature, the copper wire 100 is annealed, which can effectively reduce the stress concentration phenomenon caused by rapid temperature changes inside the material and improve the physical and mechanical properties of the wire. The copper wire 100 is gradually cooled to a suitable temperature and then enters the cooling pool 11 from the lower guide tube 4 for cooling. Finally, a copper wire 100 with high wear resistance, fatigue strength and toughness is obtained.

[0029] See Figure 1 , Figure 5 and Figure 6As shown, the cooling pool 11 includes a water storage frame 111 fixedly installed on one side of the top of the base 1. The top of the water storage frame 111 is open and the inside stores water for cooling copper wires 100. The water storage frame 111 is connected to multiple inlet pipes 112 on the side facing the mounting frame 2. The inlet pipes 112 are respectively connected to the guide pipes 4 at the bottom. The inside of the water storage frame 111 is a cooling pipe 113 connected to the inlet pipes 112. The cooling pipe 113 is a pipe with an open upper half and multiple through holes are opened on the bottom wall of the cooling pipe 113. The water level of the cooling water in the water storage frame 111 is higher than that of the cooling pipe 113. The copper wires 100, after being gradually cooled and annealed, will enter the cooling pipes 113 sequentially from the inlet pipes 112 and be cooled by the cooling water in the water storage frame 111 in the cooling pipes 113.

[0030] See Figure 6 As shown, a discharge frame 114 is fixedly installed on the side of the water storage frame 111 away from the inlet pipe 112. The refrigeration pipe 113 is connected to the discharge frame 114. A guide plate 115 is fixedly connected at an inclination inside the discharge frame 114. The guide plate 115 is inclined downward toward the refrigeration pipe 113. The guide plate 115 is used to guide the cooled copper wire 100 in the refrigeration pipe 113 so that the annealed copper wire 100 can be concentrated for subsequent processing.

[0031] See Figure 4 As shown, each guide tube 4 has a symmetrically fixed partition block 41 inside its tube wall. The partition block 41 is sealed and separated inside the guide tube 4. The partition block 41 is used to support the copper wire 100 transmitted inside the guide tube 4, and at the same time seals and separates the first heating tube 5, the second heating tube 6 and the third heating tube 7 to avoid mutual temperature influence and disturbance between the first heating tube 5, the second heating tube 6 and the third heating tube 7.

[0032] See Figure 4 As shown, support blocks 10 are fixedly installed at the bends of the inner walls of the first heating tube 5, the second heating tube 6 and the third heating tube 7. The support blocks 10 are used to support and guide the copper wire 100, so that the copper wire 100 can be smoothly transmitted in the first heating tube 5, the second heating tube 6 and the third heating tube 7, reducing the risk of bending and breakage of the copper wire 100 during the heating and annealing process.

[0033] When annealing the hardened copper wire 100 after the stretching process using the device, firstly, the winding reel 31 loaded with the hardened copper wire 100 to be annealed is installed on the placement plate 3. Then, the hardened copper wire 100 is led out from the winding reel 31 and sequentially threaded into a continuous bending annealing pipe composed of the first heating tube 5, the second heating tube 6, the third heating tube 7, and three sets of guide tubes 4 connecting them. During the continuous traction of the copper wire 100, the temperature control module 9 is activated simultaneously to continuously monitor the temperature. The heating power of the induction heating coil 8, spirally wound on the first heating tube 5, the second heating tube 6, and the third heating tube 7, is controlled to ensure that a preset gradient temperature field is formed inside the tubes: the first heating tube 5 has the highest temperature, the second heating tube 6 is next, and the third heating tube 7 has the lowest temperature. This gradually decreasing gradient annealing method can effectively reduce stress concentration inside the copper wire 100 caused by rapid temperature changes. When the copper wire 100 that has completed gradient annealing is led out from the lower guide tube 4, it immediately enters the inlet pipe 112 of the cooling pool 11 and flows into the storage tank. The cooling water level inside the water frame 111 is higher than that of the cooling pipe 113, which has an upper half opening and a through hole at the bottom. Cooling water continuously flows in and soaks the copper wire 100 flowing through the cooling pipe 113, achieving rapid and uniform cooling. The cooled copper wire 100 then enters the discharge frame 114 through the cooling pipe 113 and is smoothly discharged upwards by the inclined guide plate 115 inside the discharge frame 114, facilitating centralized collection. Ultimately, high-quality copper wire 100 with high wear resistance, high fatigue strength, and high toughness is obtained. Since each guide tube 4 has a partition block 41 on its inner wall to support the copper wire 100 in transmission and seal and separate adjacent heating tube sections (such as separating the area between the first heating tube 5 and the second heating tube 6, and between the second heating tube 6 and the third heating tube 7), mutual interference between different temperature ranges can be avoided. At the same time, the support block 10 set at the corner bend of the inner wall of the first heating tube 5, the second heating tube 6 and the third heating tube 7 provides support and smooth guidance for the copper wire 100, prevents bending and damage, and improves the stability of the copper wire 100 during the annealing process.

[0034] See Figure 1 , Figure 7 and Figure 8As shown, the conveying mechanism 12 includes two fixed plates 121 symmetrically fixedly connected to the top of the mounting frame 2. Two sets of roller conveyor belts 122 are symmetrically mounted on the upper and lower sides of the ends of the fixed plates 121. The upper and lower sets of roller conveyor belts 122 are parallel to each other and can jointly clamp the copper wire 100 and drive it forward. A gear 123 is fixedly connected to one of the rollers in the roller conveyor belt 122. The gears 123 on the upper and lower sets of roller conveyor belts 122 mesh with each other. A first motor 124 is fixedly installed on one of the fixed plates 121. The output shaft of the first motor 124 is connected to the roller of one set of roller conveyor belts 122, which pulls the copper wire 100 on the winding reel 31 between the two sets of roller conveyor belts 122. The first motor 124 then drives the upper and lower sets of roller conveyor belts 122 through the meshing of the gear 123 to drive the copper wire 100 into the first heating tube 5 for annealing.

[0035] See Figure 1 , Figure 7 and Figure 9 As shown, a guide mechanism 13 is provided on the top of the mounting frame 2 near the conveying mechanism 12. The guide mechanism 13 is connected to the conveying mechanism 12 by a precision guide copper wire. The guide mechanism 13 includes two mounting plates 131 symmetrically and fixedly connected to one side of the top of the mounting frame 2. A guide rod 132 is fixedly connected between the mounting plates 131. Multiple guide blocks 133 are slidably connected to the guide rod 132. A lead screw 134 is rotatably connected between the mounting plates 131. The lead screw 134 and the guide rod 132 are parallel to each other. One side of the mounting plate 131 is fixedly mounted with... There is a second motor 135, the output shaft of the second motor 135 is connected to the lead screw 134, and the guide blocks 133 are arranged in pairs. The number of threaded sections on the lead screw 134 and the guide blocks 133 are the same and arranged in opposite directions. Each guide block 133 is threadedly engaged with the corresponding threaded section on the lead screw 134. The second motor 135 drives the lead screw 134 to rotate, so that the lead screw 134 can synchronously drive multiple sets of guide blocks 133 to limit the corresponding copper wires 100, so that the copper wires 100 can be accurately transmitted to the corresponding first heating tube 5.

[0036] See Figure 7 and Figure 9 As shown, the side of the guide block 133 facing the winding reel 31 is an inclined guide plate. The inclined guide plate of the guide block 133 can correctly guide the copper wire 100, saving the manual alignment operation required when initially pulling the copper wire 100.

[0037] To improve the transmission accuracy and efficiency of the copper wire 100, the guide mechanism 13 and the conveying mechanism 12 on the mounting frame 2 can be used. First, the second motor 135 of the guide mechanism 13 is activated. The second motor 135 drives the lead screw 134 to rotate. The rotating lead screw 134 can synchronously drive multiple sets of guide blocks 133 to move on the guide rod 132. Each guide block 133 precisely limits the corresponding copper wire 100 towards the inclined guide plate of the winding reel 31, guiding the copper wire 100 to the entrance of the conveying mechanism 12. Then, the copper wire 100 is fed into the upper and lower sets of parallel roller conveyor belts 122 of the conveying mechanism 12. Then, the first motor 124 is activated, which drives the rollers of one set of roller conveyor belts 122 to rotate. Since the gears 123 fixedly connected to one of the rollers in the upper and lower sets of roller conveyor belts 122 mesh with each other, the power of the first motor 124 is synchronously transmitted to the other set of roller conveyor belts 122 through the meshing of the gears 123, so that the upper and lower sets of roller conveyor belts 122 rotate synchronously in opposite directions, together clamping the copper wire 100 and providing a stable forward traction force, and finally accurately and continuously conveying the copper wire 100 into the corresponding first heating tube 5, and then the continuous annealing and cooling process can begin.
