Description
Technical Field
[0001] This utility model relates to the field of casting equipment technology, specifically to a constant-temperature casting equipment for thin strip steel continuous casting. Background Technology
[0002] The constant temperature casting thin strip steel continuous casting equipment is a high-efficiency metal casting equipment, mainly used for the production of thin strip steel. The core of this equipment is that it can maintain the temperature of the molten metal during the casting process, thereby improving the consistency of the cast strip, ensuring the production quality of the cast strip and improving the production efficiency of the cast strip.
[0003] In the constant temperature casting of thin strip steel, the support guide roller can effectively support the high temperature thin strip steel that has just been extruded from the gap of the casting roller, preventing it from sagging or deforming under its own weight or the traction force of the subsequent equipment, ensuring that the casting strip can be smoothly transported forward and maintain its good shape and dimensional accuracy.
[0004] During the transport of the cast strip, the cast strip applies a certain pressure to the support guide roller. Due to the slag on the surface of the cast strip, when the cast strip passes through the guide roller, the presence of slag will change the contact state between the cast strip and the guide roller, causing the local pressure of the guide roller to increase or decrease. This uneven pressure distribution will cause wear or deformation on the surface of the guide roller, thus affecting the support effect of the guide roller. If the guide rail is not replaced or repaired in time, it will affect the transport quality and shape accuracy of the cast strip. Therefore, a constant temperature casting thin strip continuous casting device is proposed to address the above problems. Utility Model Content

[0024] 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.
[0025] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0026] Please see Figure 1-7 This utility model provides a technical solution:
[0027] A constant-temperature casting device for thin strip steel includes a support block 1 and a support guide roller frame 2. A guide roller 3 is installed inside the support guide roller frame 2. An early warning mechanism 4 is fixedly connected to the upper end of the support block 1. A transmission mechanism 5 is fixedly connected to the upper end of the support block 1. The early warning mechanism 4 includes a column 41. A fixed shaft 42 is fixedly connected to the inner side of the column 41. A half gear 43 is rotatably connected to the outer side of the fixed shaft 42. A spring 44 is fixedly connected to the inner side of the half gear 43. The transmission mechanism 5 includes a mounting frame 51. A cavity 52 is opened inside the mounting frame 51. A round hole 53 is opened at the upper end of the mounting frame 51. A partition 54 is fixedly installed inside the mounting frame 51. A transmission component 55 is installed inside the mounting frame 51.
[0028] As a further implementation of this solution, two circular holes 53 are provided, which are symmetrically distributed on the upper end of the mounting bracket 51. The partition plate 54 is rectangular in shape, and the outer side of the partition plate 54 is closely fitted with the inner side of the cavity 52. Several transmission components 55 are provided, which are evenly and equidistantly distributed on the inner side of the cavity 52. This arrangement facilitates the injection of lubricating fluid into the cavity 52 through the circular holes 53, so that the lubricating fluid enters the cavity 52 more evenly and avoids the situation of uneven distribution of lubricating fluid due to a single injection port.
[0029] As a further implementation of this scheme, two columns 41 are provided, which are symmetrically distributed on the upper end of the support block 1. The included angle between the fixed shaft 42 and the columns 41 is 90°. The central axis of the fixed shaft 42 and the central axis of the half gear 43 are on the same straight line. Several half gears 43 are provided, which are evenly and equidistantly distributed on the outside of the fixed shaft 42. The number of springs 44 corresponds to the number of half gears 43. This arrangement can strengthen the mutual support between components, improve the stability of the device, and make the components evenly distributed, which is convenient for observing the working status of the components.
[0030] As a further implementation of this solution, the transmission assembly 55 includes a return spring 551, a transmission block 552 fixedly connected to the bottom end of the return spring 551, a curved groove 553 opened at the upper end of the transmission block 552, a transmission column 554 fixedly connected to the inner side of the transmission block 552, a ball bearing 555 installed on the inner side of the transmission column 554, a through hole 556 opened on the outer side of the transmission column 554, a sponge strip 557 provided on the inner side of the transmission column 554, and a toothed block 558 fixedly connected to the lower end of the transmission block 552. The curved groove 553 can collect the dripping lubricating fluid, which adheres to the surface of the return spring 551 during the deformation process, preventing the return spring 551 from rusting and avoiding the waste of lubricating fluid.
[0031] As a further implementation of this solution, a partition 54 is fixedly connected to the upper end of the return spring 551. The central axis of the return spring 551 and the central axis of the transmission column 554 are on the same straight line. The angle between the transmission column 554 and the mounting bracket 51 is 90°. The transmission column 554 slides inside the mounting bracket 51. This arrangement enables the return spring 551 to provide an upward elastic force to the transmission block 552, so that the transmission block 552 can drive the transmission column 554 to quickly return to the initial position when it is not subjected to external force.
[0032] As a further implementation of this solution, the vertical projection of the transmission block 552 is elliptical. The transmission block 552 and the transmission column 554 are on the same axis. The curved groove 553 is located below the partition plate 54, and the through hole 556 is located above the partition plate 54. Several through holes 556 are provided. The through holes 556 are evenly and equidistantly distributed in a ring array on the outside of the transmission column 554. This ensures that the transmission block 552 can move vertically up and down while minimizing the friction between it and the mounting bracket 51.
[0033] As a further implementation of this solution, the upper end of the sponge strip 557 is attached to the outer side of the ball 555, the outer side of the ball 555 is attached to the outer side of the guide roller 3, the position of the toothed block 558 corresponds one-to-one with the position of the half gear 43, and one side of the toothed block 558 meshes with one side of the half gear 43. This arrangement allows the lubricant in the sponge strip 557 to be applied to the surface of the ball 555, thereby reducing the surface friction of the ball 555 and preventing excessive friction when the ball 555 contacts the guide roller 3.
[0034] Workflow: Before using the device, first inspect it to ensure the mechanical structure is intact and all components are securely installed without looseness. Then, adjust the position of the support guide roller frame 2 according to the width, thickness, and other specifications of the thin strip steel, ensuring the inlet of the support guide roller frame 2 matches the running trajectory of the strip steel. This ensures the strip steel can smoothly enter the support guide roller frame 2. When the cast strip enters the support guide roller frame 2, several guide rollers 3 installed on the inner side of the support guide roller frame 2 will guide and support the cast strip, ensuring the strip steel can pass through the support guide roller frame 2 smoothly and accurately. During prolonged use, the guide rollers 3 will also rotate due to the friction from the cast strip when supporting and clamping it. When the cast strip... When slag scratches the guide roller 3, it will cause uneven scratches on the surface of the guide roller 3. Since the outer side of the guide roller 3 is in contact with the outer side of the ball 555, when the guide roller 3 rotates, the scratches on the surface will exert varying degrees of pressure on the ball 555. When the guide roller 3 exerts more pressure on the ball 555, when the ball 555 moves downward, it will drive the toothed block 558 to move downward through the transmission block 552 fixedly connected to the outer side of the transmission column 554. The downward movement of the toothed block 558 will drive the half gear 43 meshing on one side to rotate. When the half gear 43 rotates, it will drive the fixedly connected spring 44 to move. Since the spring 44 has good elasticity, it will vibrate while moving. When the roller 3 compresses the ball 555 less, the return spring 551 recovers its deformation, causing the transmission block 552 to move quickly toward the partition 54. The movement of the transmission block 552 will cause the toothed block 558 fixedly connected at the bottom to move upward. The upward movement of the toothed block 558 will cause the half gear 43 meshing on one side to quickly return to its original position. During the return process of the half gear 43, the vibration of the fixedly connected spring 44 will be intensified, making it easier for the staff to notice and quickly identify the damaged part. When the device is used for a long time, lubricating fluid can be injected into the cavity 52 through the round hole 53. The lubricating fluid in the cavity 52 will enter the transmission column 554 through the through hole 556 and soak into the cavity. In the sponge strip 557, when the ball 555 rotates, the lubricant in the sponge strip 557 will be applied to the surface of the ball 555 to reduce the surface friction of the ball 555 and prevent excessive friction when the ball 555 contacts the guide roller 3. At the same time, the lubricant inside the cavity 52 will make the sliding of the transmission column 554 in the mounting bracket 51 and the partition 54 smoother. Due to the curved groove 553 opened at the upper end of the transmission block 552, even if the lubricant drips, it will be collected by the transmission block 552 and adhere to the surface of the return spring 551 during the deformation process of the return spring 551, preventing the return spring 551 from rusting, avoiding the waste of lubricant, and extending the service life of the device components.
