Description

Technical Field

[0001] This utility model relates to the technical field of annealing equipment, specifically an automatic annealing device for nickel strip after cold rolling. Background Technology

[0002] Cold-rolled nickel strip typically requires annealing. The cold rolling process alters the grain structure of the nickel strip, increasing the material's hardness and brittleness. Annealing restores the material's plasticity and ductility, and eliminates the internal stresses generated during cold rolling.

[0003] In existing technologies, nickel strip annealing mechanisms keep the nickel strip fixed during annealing, which can easily lead to uneven heating. A fixed nickel strip may experience localized overheating or underheating during the heating process, resulting in uneven temperature distribution across different parts of the strip. This affects the annealing effect, causing uneven physical and mechanical properties of the nickel strip, thus impacting the quality and performance of the final product. Furthermore, uneven heating can lead to inconsistent annealing effects in different areas of the nickel strip, potentially preventing the effective release of internal stress in some areas, resulting in unstable performance or localized stress concentration problems in the final nickel strip. Therefore, we propose an automatic annealing device for nickel strip after cold rolling to solve the above problems. Utility Model Content

[0005] Therefore, the technical solution adopted by this utility model is as follows:

Each control component includes two drive rollers; one drive roller is rotatably connected to one end of the annealing furnace's inner cavity, and the other drive roller passes through the annealing furnace and is fixedly connected to a pulley. A rotating drum is fixedly connected to the end of each drive roller near the center of the annealing furnace. The outer ring wall of the rotating drum has multiple toothed grooves. The two ends of the annealing furnace's inner cavity... Each component is fixedly connected to an internal gear ring. Multiple rotating seats are provided between the internal gear ring and the rotating cylinder. Multiple teeth matching the tooth grooves are fixedly connected around the rotating seats. The rotating seats are meshed with the rotating cylinder and the internal gear ring. The tensioning assembly includes multiple connecting rollers. The multiple connecting rollers are respectively fixedly connected to the side of the multiple rotating seats away from the center of the annealing furnace. A fixed cylinder is sleeved on the surface of the connecting roller. A moving plate is fixedly connected to one end of the connecting roller inside the fixed cylinder. A telescopic spring is provided between the moving plate and the fixed cylinder.

[0007] Preferably, the annealing furnace has multiple closed doors on its surface, and a driving component is provided on one side of the annealing furnace. Both the driving component and the control component are equipped with pulleys at their respective ends, and the driving component drives the control component to move through the pulleys.

[0008] Preferably, the plurality of toothed grooves are evenly distributed around the axis of the rotating cylinder, and the inner toothed rings at both ends are symmetrically distributed along the axis of the annealing furnace.

[0009] Preferably, the internal toothed ring is sleeved on the surface of the rotating drum, and the inner wall of the internal toothed ring does not contact the surface of the rotating drum.

[0010] Preferably, the plurality of rotating seats are evenly distributed around the axis of the rotating cylinder, and two clamping plates are installed on the side of the rotating seat near the center of the annealing furnace.

[0011] Preferably, the two clamping plates are fixedly connected to each other at their far ends by an elastic element, and the two clamping plates are fixedly connected to each other at their near ends by a fitting seat, and the two fitting seats are fixedly connected to each other at their near ends by a nickel strip body.

[0012] Preferably, the connecting roller is slidably connected to the inner wall of the fixed cylinder, the moving plate is slidably connected to the inner wall of the fixed cylinder, and the annealing furnace has guide ring grooves at both ends near the inner cavity. The ends of the multiple fixed cylinders away from the rotating seat are slidably connected to the groove wall of the guide ring groove.

[0013] Preferably, a fixing frame is provided between the plurality of fixed cylinders and the drive roller, and a fixing ring is fixedly connected to both ends of the fixing frame. The fixing rings at both ends are respectively sleeved on the surface of the fixed cylinder and the drive roller.

[0015] In this invention, the driving component drives the control assembly via a pulley, and the drive roller in the control assembly drives the rotating drum to rotate. The toothed grooves on the rotating drum mesh with the inner toothed ring, ensuring stable rotation. The rotating seat, through the meshing of its teeth with the rotating drum and the inner toothed ring, ensures that the nickel strip rotates along the axis within the annealing furnace and maintains its own rotation. This design ensures that the nickel strip rotates uniformly around the annealing furnace axis during heating, maintaining consistent temperature throughout. The device also includes a coordinated design of connecting rollers, a fixed cylinder, and a moving plate. The fixed cylinder slides within the guide ring groove, and the moving plate slides on the inner wall of the fixed cylinder, providing stable support and sliding connection. The elasticity of the telescopic spring allows the rotating seat to move at both ends of the annealing furnace cavity, thereby stretching the nickel strip and preventing it from bending or overlapping during annealing. Through the structural design of the rotating drum and rotating seat, the nickel strip rotates uniformly within the annealing furnace, avoiding localized overheating or underheating. This process ensures consistent annealing effects in different areas of the nickel strip, improving overall production quality. The stretching assembly effectively prevents the nickel strip from bending or overlapping, further improving production efficiency and product quality. In addition, multiple components such as the drive unit, control unit and rotary drum can work automatically in coordination, which improves the automation level of the production process, reduces the possibility of human intervention and operational errors, and improves the uniformity and production efficiency of the nickel strip annealing process, thus ensuring high-quality production results.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figures 1-6 As shown, this utility model provides an automatic annealing device for nickel strip after cold rolling, including a workbench 1, an annealing furnace 101 installed on the top of the workbench 1, multiple closed doors 102 opened on the surface of the annealing furnace 101, control components 2 installed at both ends of the inner cavity of the annealing furnace 101, a stretching component 3 provided on the side of the control component 2 away from the center of the annealing furnace 101, a driving component 103 provided on one side of the annealing furnace 101, and pulleys 104 installed at the ends of the driving component 103 and the control component 2 that are close to each other. The driving component 103 drives the control component 2 to move through the pulleys 104. With the cooperation of multiple components, the driving component 103 can drive the driving roller 201 in the control component 2 to rotate, so that the nickel strip body 210 can move in the annealing furnace 101 in the subsequent process.

[0025] Furthermore, the control component 2 includes two drive rollers 201. One drive roller 201 is rotatably connected to one end of the inner cavity of the annealing furnace 101, and the other drive roller 201 passes through the annealing furnace 101 and is fixedly connected to the pulley 104. A rotating drum 202 is fixedly connected to one end of the drive roller 201 near the center of the annealing furnace 101. The outer ring wall of the rotating drum 202 has multiple toothed grooves 203, which are evenly distributed around the axis of the rotating drum 202. Both ends of the inner cavity of the annealing furnace 101 are also connected to the rotating drum 201. An internal gear ring 204 is fixedly connected, with both ends of the internal gear ring 204 symmetrically distributed along the axis of the annealing furnace 101. The internal gear ring 204 is sleeved on the surface of the rotating cylinder 202, but the inner ring wall of the internal gear ring 204 does not contact the surface of the rotating cylinder 202. Multiple rotating seats 205 are provided between the internal gear ring 204 and the rotating cylinder 202, and the multiple rotating seats 205 are evenly distributed around the axis of the rotating cylinder 202. Multiple teeth 206 that match the tooth grooves 203 are fixedly connected around the rotating seats 205. The rotating seats 205 and the rotating cylinder 202 are connected to the rotating cylinder 202. The cylinder 202 is engaged with the rotating seat 205 and the internal gear ring 204. Two clamping plates 207 are installed on the side of the rotating seat 205 near the center of the annealing furnace 101. The end faces of the two clamping plates 207 that are far apart from each other are fixedly connected to elastic elements 208. The end faces of the two clamping plates 207 that are close to each other are fixedly connected to fitting seats 209. The end faces of the two fitting seats 209 that are close to each other are fixedly connected to nickel strip bodies 210. The drive roller 201 drives the rotating cylinder 202 to rotate, while its internal gear ring 204 remains stationary. This allows multiple rotating seats 205 around the annealing furnace 101 to rotate around the axis of the annealing furnace 101 while maintaining their own rotation. Consequently, the nickel strip bodies 210 fixed on one side of the rotating seat 205 move synchronously. This allows multiple nickel strips to rotate around the axis of the annealing furnace 101 while maintaining their own rotation during annealing. This prevents local overheating or underheating during the heating process, resulting in a more uniform temperature distribution in all parts of the nickel strip.

[0026] Furthermore, the stretching assembly 3 is provided with multiple connecting rollers 301, which are respectively fixedly connected to the side of multiple rotating seats 205 away from the center of the annealing furnace 101. A fixed cylinder 302 is sleeved on the surface of the connecting roller 301, and the connecting roller 301 is slidably connected to the inner wall of the fixed cylinder 302. A moving plate 303 is fixedly connected to one end of the connecting roller 301 inside the fixed cylinder 302, and the moving plate 303 is slidably connected to the inner wall of the fixed cylinder 302. Guide ring grooves 305 are opened at both ends near the inner cavity of the annealing furnace 101. The ends of the multiple fixed cylinders 302 away from the rotating seats 205 are slidably connected to the groove wall of the guide ring grooves 305. A telescopic spring is provided between the moving plate 303 and the rotating seat 205. A spring 304 is used, and a fixing frame 306 is provided between multiple fixing cylinders 302 and the drive roller 201. Fixing rings 307 are fixedly connected to both ends of the fixing frame 306. The two fixing rings 307 are respectively sleeved on the surface of the fixing cylinders 302 and the drive roller 201. The fixing cylinders 302 and the inner wall of the fixing rings 307 are slidably connected, and the drive roller 201 and the inner wall of the fixing rings 307 are slidably connected. Under the elastic force of the telescopic spring 304, its rotating seat 205 will move towards both ends of the inner cavity of the annealing furnace 101 to stretch multiple nickel strip bodies 210, preventing the nickel strips from bending and overlapping during the annealing process, further ensuring that the annealing effect of different areas of the nickel strip is consistent and improving the overall production quality.

[0027] Working principle: The drive component 103 in the device drives the control component 2 to move through the pulley 104. The drive roller 201 in the control component 2 drives the rotating drum 202 to rotate. The meshing of the toothed groove 203 on the rotating drum 202 with the inner toothed ring 204 ensures that the rotating drum 202 can rotate stably. The rotating seat 205 meshes with the rotating drum 202 and the inner toothed ring 204 through the teeth 206, ensuring that the nickel strip maintains its own rotation while rotating along the axis in the annealing furnace 101. In this way, the nickel strip can rotate evenly around the axis of the annealing furnace 101 during the heating process, ensuring that all parts of the nickel strip are heated evenly. The connecting roller 301 cooperates with the moving plate 303 through the fixed cylinder 302. The fixed cylinder 302 slides in the guide ring groove 305, and the moving plate 303 slides on the inner wall of the fixed cylinder 302. The fixing frame 306 between the fixed cylinder 302 and the drive roller 201 is sleeved by the fixing ring 307, providing a stable connection. The support and sliding connection, the elastic force of the telescopic spring 304 allows the rotating seat 205 to move at both ends of the inner cavity of the annealing furnace 101, thereby stretching the nickel strip and preventing it from bending or overlapping during the annealing process. Through the structural design of the rotating drum 202 and the rotating seat 205, the nickel strip can rotate evenly in the annealing furnace 101, avoiding the problem of local overheating or underheating, and achieving a uniform temperature distribution in all parts of the nickel strip. By maintaining the uniform rotation and stretching of the nickel strip during the annealing process, the annealing effect of the nickel strip in different areas is ensured to be consistent, thereby improving the overall production quality. The design of the stretching component 3 prevents the nickel strip from bending or overlapping during the annealing process, ensuring the stability and consistency of the nickel strip, further improving production efficiency and product quality. Multiple components in the device, such as the drive component 103, the control component 2, the rotating drum 202, etc., can work automatically in coordination, improving the automation level of the production process.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
