Description

Technical Field

[0001] The invention relates to the technical field of nickel-chromium wire drawing production, in particular to an annealing and anti-oxidation device. Background Art

[0002] Nickel-chromium wire drawing is a process commonly used to make filaments, wires or cords, which are commonly used in heating elements, resistance wires, wires, cables and various industrial and electronic applications. After the nickel-chromium wire drawing is completed, it needs to be annealed and anti-oxidation treated.

[0003] The patent with application number CN202221770792.7 provides a vacuum annealing device for nickel-chromium wire drawing production, including a bracket and a nickel-chromium wire, and also including an annealing box, a vacuum tube and a cooling cylinder. The annealing box is fixed on the bracket, and the vacuum tube is transversely arranged on the annealing box. The cooling cylinder is arranged on the right side of the annealing box. The cooling cylinder is fixedly sleeved on the vacuum tube. An air inlet interface is arranged on the vacuum tube between the annealing box and the cooling cylinder. The nickel-chromium wire is arranged in the vacuum tube. Hydrogen is introduced into the vacuum tube through the gas interface. Removing the air from the vacuum tube can prevent the nickel-chromium wire from being oxidized in the vacuum tube, thereby ensuring the quality of the product. In addition, a cooling cylinder is arranged at the right end of the vacuum tube, and coolant enters the cooling cylinder through a water inlet to cool the nickel-chromium wire, thereby accelerating the cooling rate after wire drawing annealing and improving production efficiency. However, when this device anneals the nickel-chromium wire after wire drawing, oxides will exist on the surface of the nickel-chromium wire, and some of the oxides will fall into the annealing box, thereby affecting the temperature uniformity inside the annealing box, thereby affecting the annealing effect of the nickel-chromium wire. Therefore, an annealing anti-oxidation device is proposed to solve the above-mentioned problems. Summary of the invention

The surface of the arc block after moving contacts with the surface of the inclined block. A spring is arranged between the inclined block and the fixed block. After the nickel-chromium wire passes through the wire drawing machine for wire drawing, it enters the annealing box for annealing under the guidance of the guide roller. The annealed nickel-chromium wire passes through the support plate, and the moving ring is moved before the annealing process, so that the moving ring drives the arc block to move. The arc block pushes the inclined block to move through the arc surface, and the inclined block drives the moving rod to move. The moving rod pushes the elastic scraper to move through the connecting plate. At this time, the three elastic scrapers gather and contact with the nickel-chromium. The surface of the wire is in contact with the guide plate, so that the oxide on the surface of the nickel-chromium wire can be scraped off to prevent the oxide from entering the subsequent annealing box and falling off, and also to prevent the oxide from affecting the subsequent coating of the antioxidant on the surface of the nickel-chromium wire. The scraped oxide will fall on the guide plate and fall into the bottom wall inside the box, which is convenient for the subsequent unified discharging and recycling. After that, the nickel-chromium wire will enter the annealing box for annealing. After annealing is completed, the nickel-chromium wire passes through the fixed plate and contacts the brush plate.

At this time, the through hole on the moving block connects the material box and the turntable, and the antioxidant in the material box enters the turntable through the through hole and contacts the brush plate, so that the brush plate can brush the antioxidant on the surface of the nickel-chromium wire. When the moving block is away from the turntable, the sealing rubber plate is reset and sealed under its own elastic force, so that the antioxidant in the material box no longer enters the turntable, so that the antioxidant can be discharged intermittently and then applied, preventing the antioxidant from being continuously discharged and causing dripping waste, and can also increase the service life of the antioxidant and reduce the frequency of replenishing the antioxidant. When there is less antioxidant in the material box, the material box rotates to the bottom. At this time, the moving block is located on the side away from the turntable and on the inclined plate The storage block faces upward, allowing the antioxidant to enter the storage block. When the material box rotates to the top, the moving block will be located on the side close to the turntable. At this time, the storage block faces downward, and the antioxidant inside will slide out and be discharged through the through hole for smearing. If there is no storage block, the antioxidant will flow from the arc surface of the turntable to both sides, resulting in no antioxidant being discharged from the through hole in the middle. At the same time, when there is sufficient antioxidant inside the material box, the movement of the moving block will drive the inclined plate to move, and the inclined plate is inclined when the antioxidant moves, and then a thrust can be applied to the inclined plate in the reverse direction, so that the inclined plate drives the moving block to rotate, and the rotating inclined plate can improve the fluidity of the antioxidant and improve its discharge and smearing effect.

When the material box 53 rotates upward again, the moving block 65 will move to the side close to the turntable 51 under the action of gravity. At this time, the moving block 65 will contact the sealing rubber plate 67 on the inner wall of the turntable 51 and push the sealing rubber plate 67 to open, so that the moving block 65 enters the turntable 51. At this time, the through hole 66 on the moving block 65 will connect the material box 53 and the turntable 51, and the antioxidant in the material box 53 will enter the turntable 51 through the through hole 66 and contact the brush plate 52, so that the brush plate 52 can brush the antioxidant on the surface of the nickel-chromium wire. When the moving block 65 is away from the turntable 51, the sealing rubber plate 67 is reset and sealed under its own elastic force, so that the antioxidant in the material box 53 no longer enters the turntable 51, so that the antioxidant can be discharged intermittently and then applied, to prevent the antioxidant from being continuously discharged and causing dripping waste, and also to increase the service life of the antioxidant and reduce the replenishment frequency of the antioxidant.The smearing device 6 also includes an inclined plate 671 and a receiving block 672.

[0027] Working principle: after the nickel-chromium wire passes through the wire drawing machine 2 for wire drawing, it enters the annealing box 4 for annealing under the guidance of the guide roller 3. The annealed nickel-chromium wire will pass through the support plate 21. Before the annealing process, the moving ring 27 is moved, so that the moving ring 27 drives the arc block 28 to move. The arc block 28 pushes the inclined block 25 to move through the arc surface. The inclined block 25 drives the moving rod 23 to move. The moving rod 23 pushes the elastic scraper 24 to move through the connecting plate. At this time, the three elastic scrapers 24 gather together and contact the surface of the nickel-chromium wire, so that the oxide on the surface of the nickel-chromium wire can be scraped off to prevent The oxide is prevented from entering the subsequent annealing box 4 and falling off, and the oxide is also prevented from affecting the subsequent coating of the antioxidant on the surface of the nickel-chromium wire. The scraped oxide will fall on the guide plate 29 and fall into the bottom wall inside the box 1, which is convenient for the subsequent unified discharging and recycling. After that, the nickel-chromium wire will enter the annealing box 4 for annealing. After the annealing is completed, the nickel-chromium wire passes through the fixed plate 5 and contacts the brush plate 52. At this time, the antioxidant in the material box 53 will enter the turntable 51 and contact the brush plate 52, and the brush plate 52 will apply the antioxidant on the surface of the nickel-chromium wire to prevent the surface of the nickel-chromium wire from oxidation.

[0028] When the guide roller 3 rotates driven by the motor, it will also drive the pulley set 61 to rotate, the pulley set 61 will drive the worm 62 to rotate, the worm 62 will drive the worm wheel 63 to rotate, the worm wheel 63 will drive the turntable 51 to rotate, the turntable 51 will drive the material box 53 to rotate, when the material box 53 rotates to the bottom, the moving block 65 will move on the guide column 64 to the side away from the turntable 51 under the action of gravity, when the material box 53 rotates to the top again, the moving block 65 will move to the side close to the turntable 51 under the action of gravity, at this time the moving block 65 will seal against the inner wall of the turntable 51. The rubber plate 67 contacts and pushes the sealing rubber plate 67 to open, so that the moving block 65 enters the turntable 51. At this time, the through hole 66 on the moving block 65 connects the material box 53 and the turntable 51, and the antioxidant in the material box 53 enters the turntable 51 through the through hole 66 and contacts the brush plate 52, so that the brush plate 52 can brush the antioxidant on the surface of the nickel-chromium wire. When the moving block 65 moves away from the turntable 51, the sealing rubber plate 67 resets and seals under its own elastic force, so that the antioxidant in the material box 53 no longer enters the turntable 51, so that the antioxidant can be discharged intermittently. The antioxidant can be discharged and then applied to prevent the antioxidant from being continuously discharged and causing dripping and waste. It can also increase the service life of the antioxidant and reduce the frequency of replenishing the antioxidant. When the antioxidant in the material box 53 is less, the material box 53 rotates to the bottom. At this time, the moving block 65 is located on the side away from the turntable 51 and the storage block 672 on the inclined plate 671 faces upward, so that the antioxidant enters the storage block 672. When the material box 53 rotates to the top, the moving block 65 will be located on the side close to the turntable 51. At this time, the storage block 672 faces downward, and the antioxidant inside will slide out and pass through the through hole. 66 is discharged for application. If there is no receiving block 672, the antioxidant will flow from the arc surface of the turntable 51 to both sides, resulting in no antioxidant being discharged from the middle through hole 66. At the same time, when there is sufficient antioxidant inside the material box 53, the movement of the moving block 65 will drive the inclined plate 671 to move, and the inclined plate 671 is inclined to move the antioxidant, and then a thrust can be applied to the inclined plate 671 in the reverse direction, so that the inclined plate 671 drives the moving block 65 to rotate, and the rotating inclined plate 671 can improve the fluidity of the antioxidant and improve its discharge and application effect.

When the movable ring 27 moves, it will drive the inner cylinder 72 to move on the inner wall of the outer cylinder 71, and the inner cylinder 72 and the outer cylinder 71 can block the annealed nickel-chromium wire, which can reduce the contact between air and the annealed nickel-chromium wire and prevent it from being oxidized again; the protective device 7 also includes a mounting plate 731, a brush rod 732 and a push plate 733. The mounting plate 731 is fixedly connected to the inner wall of the inner cylinder 72.

When the turntable 51 rotates, the push plate 733 will be driven to rotate, and the push plate 733 will push the transmission plate 73 to rotate, and the push plate 733 will drive the inner cylinder 72 to rotate, and the inner cylinder 72 will drive the mounting plate 731 to rotate, and the mounting plate 731 will drive the brush rod 732 to brush the annealed nickel-chromium wire again, and further brush off the residual oxide on the surface of the annealed nickel-chromium wire, to ensure that there is no oxide residue on the surface of the nickel-chromium wire when the antioxidant is subsequently applied.

[0030] The discharging device 8 includes a fixed ring 81, a clamping plate 82, a clamping rod 83, a rotating plate 84, an arc plate 85 and a support block 86. The fixed ring 81 is movably connected to the inner wall of the inner cylinder 72, the clamping plate 82 is fixedly connected to the inner surface of the fixed ring 81, the clamping rod 83 is fixedly connected to the left side of the clamping plate 82, the rotating plate 84 is rotatably connected to the inner wall of the fixed ring 81 through a torsion spring, and the support block 86 is fixedly connected to the right side of the fixed ring 81. When the push plate 733 rotates, it will contact the arc plate 85 and push the arc plate 85 to rotate through the arc surface. The arc plate 85 will push the rotating plate 84 to rotate, and the rotating plate 84 will push the oxide on the inner wall of the inner cylinder 72 to move to the left, so that the oxide passes through the movable ring The guide plate 29 below 27 is discharged to prevent the oxide from accumulating on the inner wall of the inner cylinder 72, and then the oxide is driven to fall on the surface of the nickel-chromium wire again when the inner cylinder 72 rotates. When the inner cylinder 72 drives the brush rod 732 to rotate, the brush rod 732 will contact the clamping rod 83 on the clamping plate 82, and the clamping rod 83 will knock off the oxide adhered to the surface of the brush rod 732, thereby realizing the self-cleaning of the brush rod 732; the discharging device 8 also includes an inner plate 861, a clamping disc 862 and an elastic rod 863. The inner plate 861 is slidably connected to the inner wall on the left side of the rotating plate 84 through an elastic member, and the clamping disc 862 is rotatably connected to the left side of the fixing ring 81 through a torsion spring. The elastic rod 863 is fixedly connected to the clamping disc 86 2; one end of the elastic rod 863 away from the chuck 862 contacts with the left side of the rotating plate 84, the bottom of the rotating plate 84 and the inner plate 861 contact with the inner wall of the inner cylinder 72, and the side of the support block 86 away from the fixed ring 81 is fixedly connected to the left side of the fixed plate 5. When the rotating plate 84 rotates, the bottom of the inner plate 861 inside it will no longer be blocked by the inner cylinder 72. At this time, the inner plate 861 is pushed out of the rotating plate 84 by the elastic member, thereby increasing the length of the rotating plate 84, thereby increasing the pushing distance of the oxidant and improving the discharge effect of the oxide. When the mounting plate 731 rotates, it will contact with the chuck 862 and drive the chuck 862 to rotate, and the chuck 862 will drive The elastic rod 863 rotates, and the elastic rod 863 will no longer contact the rotating plate 84. At this time, the mounting plate 731 passes over the rotating plate 84, and the push plate 733 contacts the arc plate 85 and pushes the rotating plate 84 to rotate. Since the elastic rod 863 does not block the rotating plate 84, the rotating plate 84 will be pushed to rotate, and then the torsion spring will drive the chuck 862 to reset, and the elastic rod 863 will deform and fall back to the left side of the opened rotating plate 84. The rotating plate 84 is driven to rotate and reset under the elastic force of the elastic rod 863 and the rotating plate 84's own torsion spring, so that the extended inner plate 861 slides on the inner cylinder 72 and is pushed back into the rotating plate 84, ensuring that the rotating plate 84 can be reset.

[0031] Working principle: when the moving ring 27 moves, it will drive the inner cylinder 72 to move on the inner wall of the outer cylinder 71, and the inner cylinder 72 and the outer cylinder 71 can block the annealed nickel-chromium wire, which can reduce the contact between air and the annealed nickel-chromium wire and prevent it from being oxidized again. At the same time, when the turntable 51 rotates, it will drive the push plate 733 to rotate, and the push plate 733 will push the transmission plate 73 to rotate, and the push plate 733 will drive the inner cylinder 72 to rotate, and the inner cylinder 72 will drive the mounting plate 731 to rotate, and the mounting plate 731 will drive the brush rod 732 to brush the annealed nickel-chromium wire again, and further brush off the residual oxide on the surface of the annealed nickel-chromium wire to ensure that there is no oxide residue on the surface of the nickel-chromium wire when the antioxidant is applied later.

[0032] When the push plate 733 rotates, it will contact the curved plate 85 and push the curved plate 85 to rotate through the curved surface. The curved plate 85 will push the rotating plate 84 to rotate. The rotating plate 84 will push the oxide on the inner wall of the inner cylinder 72 to move to the left, so that the oxide is discharged through the guide plate 29 under the moving ring 27, to prevent the oxide from accumulating on the inner wall of the inner cylinder 72, and then drive the oxide to fall on the surface of the nickel-chromium wire again when the inner cylinder 72 rotates. When the inner cylinder 72 drives the brush rod 732 to rotate, the brush rod 732 will contact the clamping rod 83 on the clamping plate 82, and the clamping rod 83 will knock off the oxide adhered to the surface of the brush rod 732, thereby realizing the self-cleaning of the brush rod 732. When the rotating plate 84 rotates, the bottom of the inner plate 861 inside it will no longer be blocked by the inner cylinder 72. At this time, the inner plate 861 is pushed out of the rotating plate 84 by the elastic member, thereby increasing the length of the rotating plate 84. This will increase the pushing distance of the oxidant and improve the discharge effect of the oxide. When the mounting plate 731 rotates, it will contact the chuck 862 and drive the chuck 862 to rotate. The chuck 862 will drive the elastic rod 863 to rotate. At this time, the elastic rod 863 will no longer contact the rotating plate 84. At this time, the mounting plate 731 passes over the rotating plate 84, and the push plate 733 contacts the arc plate 85 and pushes the rotating plate 84 to rotate. Since the elastic rod 863 does not block the rotating plate 84, the rotating plate 84 will be pushed to rotate, and then the torsion spring will drive the chuck 862 to reset, and the elastic rod 863 will deform and fall back to the left side of the opened rotating plate 84. The rotating plate 84 is driven to rotate and reset under the elastic force of the elastic rod 863 and the rotating plate 84's own torsion spring, so that the extended inner plate 861 slides on the inner cylinder 72 and is pushed back into the rotating plate 84 to ensure that the rotating plate 84 can be reset.
