Description

Technical Field

[0001] This utility model relates to the field of steel rollers, and in particular to a novel composite steel roller. Background Technology

[0002] Steel rollers are mechanical components widely used in industrial fields. They are usually made of steel and are used to plastically deform metals during metal processing. Steel rollers have a wide range of applications in metallurgical engineering, used on rolling mills to cause continuous plastic deformation of metals.

[0003] Existing steel rollers are prone to wear, cracking, and peeling due to the heat generated during high-speed rotation. Furthermore, replacement is difficult due to installation and disassembly, which consumes a lot of time and manpower, leading to long equipment downtime. Moreover, their strength, cushioning, and wear resistance are not good under different working environments and conditions. Therefore, those skilled in the art have provided a new type of composite steel roller to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a novel composite steel roller. This roller uses a spiral plate and a solenoid valve to control the flow of coolant into and out of the cooling steel roller. The slide groove and the slider are slidably connected and limited by a limiting block and bolts to achieve the sliding installation and removal of the protective layer. Alloy steel, rubber, and ceramics are combined to improve the overall performance of the steel roller.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a novel composite steel roller, comprising a steel roller body, wherein an inner layer is sleeved on the inner side wall of the steel roller body, a protective layer is sleeved on the outer side wall of the steel roller body, and a cooling structure is provided inside the inner layer;

[0006] The cooling structure includes a cavity, which is located at the center of the inner layer. The inner sidewall of the cavity is provided with a bonding plate, and a spiral plate is provided at the center of the cavity. An inlet solenoid valve is provided at the upper center of one side wall of the cavity, and a drain solenoid valve is provided at the lower center of the other side wall of the cavity.

[0007] An installation auxiliary frame is provided at the center of both sides of the steel roller body, and a connection and disassembly structure is provided at the center of the outer side wall of the steel roller body and the inner side wall of the protective layer.

[0008] The above technical solution uses a spiral plate and a solenoid valve to control the flow of coolant into and out of the cooling steel roller. The slide groove and the slider are slidably connected and limited by limit blocks and bolts to achieve the sliding installation and removal of the protective layer. Alloy steel, rubber and ceramic are combined to improve the overall performance of the steel roller.

[0009] Furthermore, the connection and disassembly structure includes four sliding grooves, four sliding blocks and four limiting blocks. The four sliding grooves are arranged in a ring on the inner side wall of the protective layer, the four sliding blocks are arranged in a ring on the outer side wall of the steel roller body, and the four limiting blocks are arranged in a ring on one side wall of the steel roller body. Bolts are provided at the upper and lower positions of the center of one side wall of each of the four limiting blocks.

[0010] The above technical solution allows the protective layer to be slidably installed and removed along the outer side wall of the steel roller body via four sliders and four grooves. During installation, tightening the bolts secures the protective layer to the steel roller body via four limiting blocks. During removal, simply loosening the bolts allows the protective layer to be easily removed for replacement or repair.

[0011] Furthermore, the four sliders are slidably connected inside the four grooves respectively;

[0012] The sliding connection method, as described above, ensures the ease of installation and removal of the protective layer.

[0013] Furthermore, both of the inner sidewalls of the mounting auxiliary brackets are provided with threads;

[0014] Through the above technical solution, the thread is mainly used for threaded connection with external fixing devices or connecting parts.

[0015] Furthermore, the steel roller body is made of alloy steel;

[0016] Through the above technical solutions, alloy steel itself has high strength and toughness, and can withstand large mechanical stresses such as torsion and bending during the operation of the steel roller body. At the same time, alloy steel has good heat resistance and can maintain good mechanical properties in high-temperature environments, ensuring that the steel roller body can continue to work under high-temperature conditions without softening or failure.

[0017] Furthermore, the inner layer is made of rubber;

[0018] Through the above technical solution, rubber has good elasticity. When the steel roller body comes into contact with other components or is subjected to certain impacts and vibrations during operation, the inner layer of rubber can play a buffering role through its own elastic deformation, reducing the impact on the internal structure of the steel roller body and avoiding cracks or damage caused by instantaneous impact.

[0019] Furthermore, the protective layer is made of ceramic.

[0020] Through the above technical solution, the ceramic material has high hardness and wear resistance, forming a hard protective layer on the surface of the steel roller body. When the steel roller body comes into contact with and rubs against the material, the ceramic protective layer can withstand the wear of the material, effectively resist the scraping and wear of the material on the steel roller body, and reduce the degree of wear on the surface of the steel roller body.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the new composite steel roller uses a spiral plate inside the cavity to control the inlet and outlet of coolant in conjunction with an inlet solenoid valve and an outlet solenoid valve, which can efficiently cool the steel roller body, more effectively reduce the thermal stress generated by the high temperature during the operation of the steel roller, and improve the service life and working performance of the steel roller.

[0023] 2. In this utility model, the protective layer is slidably connected inside the slider by a sliding groove and limited by a limiting block and bolts, which realizes the sliding installation and disassembly of the protective layer, improves the replacement and maintenance of the protective layer, and effectively saves maintenance time and costs.

[0024] 3. In this utility model, alloy steel is used as the main body of the steel roller, rubber is used as the inner layer, and ceramic is used as the protective layer. Alloy steel ensures the strength and toughness of the main body, rubber provides cushioning, and ceramic is wear-resistant, thus comprehensively improving the overall performance of the steel roller and enabling it to exhibit good performance under different working environments and conditions.

[0031] 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.

[0032] Reference Figure 1-4 This utility model provides an embodiment of a novel composite steel roller, comprising a steel roller body 1, an inner layer 2 sleeved on the inner wall of the steel roller body 1, a protective layer 3 sleeved on the outer wall of the steel roller body 1, and a cooling structure 6 inside the inner layer 2. The steel roller body 1 is made of alloy steel, which has high strength and toughness and can withstand large mechanical stresses such as torsion and bending during operation. Furthermore, alloy steel has good heat resistance and can maintain good mechanical properties at high temperatures, ensuring that the steel roller body 1 can continue to work under high-temperature conditions without softening or failure. The inner layer 2 is made of rubber, which has good... With good elasticity, when the steel roller body 1 comes into contact with other components or is subjected to certain impacts and vibrations during operation, the rubber inner layer 2 can play a buffering role through its own elastic deformation, reducing the impact on the internal structure of the steel roller body 1 and avoiding cracks or damage caused by instantaneous impact. The protective layer 3 is made of ceramic, which has high hardness and wear resistance, forming a hard protective layer 3 on the surface of the steel roller body 1. When the steel roller body 1 comes into contact with and rubs against the material, the ceramic protective layer 3 can withstand the wear of the material, effectively resisting the scraping and wear of the material on the steel roller body 1, and reducing the degree of wear on the surface of the steel roller body 1.

[0033] The cooling structure 6 includes a cavity 601 located at the center of the inner layer 2. The inner wall of the cavity 601 has a bonding plate 605, and a spiral plate 602 is located at the center of the cavity 601. An inlet solenoid valve 603 is located near the upper center of one side wall of the cavity 601, and a drain solenoid valve 604 is located near the lower center of the other side wall. Coolant enters the cavity 601 through the inlet solenoid valve 603 and flows spirally along the spiral plate 602 within the cavity 601, fully contacting the inner layer 2 for heat exchange and absorbing heat from the inside of the steel roller body 1. The coolant is then discharged through the drain solenoid valve 604, thus cooling the steel roller body 1.

[0034] The steel roller body 1 has an auxiliary mounting frame 4 at the center of both side walls. The outer side wall of the steel roller body 1 and the inner side wall of the protective layer 3 have a connection and disassembly structure 5 at the center. The inner side walls of the two auxiliary mounting frames 4 are threaded, which are mainly used for threaded connection with external fixing devices or connecting parts.

[0035] like Figure 1 , 4 As shown, the connection and disassembly structure 5 includes four sliding grooves 501, four sliding blocks 502, and four limiting blocks 503. The four sliding grooves 501 are arranged in a ring on the inner wall of the protective layer 3, the four sliding blocks 502 are arranged in a ring on the outer wall of the steel roller body 1, and the four limiting blocks 503 are arranged in a ring on one side wall of the steel roller body 1. Bolts 504 are provided at the upper and lower positions of the center of the side wall of each of the four limiting blocks 503. Through the four sliding blocks 502 and the four sliding grooves 501, the protective layer 3 can be slidably installed and disassembled along the outer wall of the steel roller body 1. During installation, tightening the bolts 504 and using the four limiting blocks 503 can firmly fix the protective layer 3 to the steel roller body 1. During disassembly, simply loosening the bolts 504 allows the protective layer 3 to be easily removed for replacement or maintenance. The four sliding blocks 502 are slidably connected inside the four sliding grooves 501, and the sliding connection method ensures the convenience of installing and disassembling the protective layer 3.

[0036] Working principle: During operation, the steel roller body 1 operates in a high-temperature environment. Coolant enters the cavity 601 at the center of the inner layer 2 through the inlet solenoid valve 603. The coolant flows spirally along the spiral plate 602 within the cavity 601, increasing the contact area between the coolant and the inner layer 2 of the steel roller body 1, allowing for more thorough heat exchange. The coolant absorbs heat from inside the steel roller body 1 and carries it away. After heat exchange, the coolant is discharged through the outlet solenoid valve 604, thus cooling the steel roller body 1 and preventing deformation or reduced hardness due to high temperatures, which could affect its performance. Regarding the performance and service life, four sliders 502 are slidably connected to the four grooves 501 respectively, allowing the protective layer 3 to be slidably installed and removed along the outer side wall of the steel roller body 1. During installation, the sliders 502 are pushed to slide into place within the grooves 501, and then the bolts 504 on the four limit blocks 503 are tightened to firmly fix the protective layer 3 to the steel roller body 1. The protective layer 3 can effectively protect the surface of the steel roller body 1 from material wear, erosion by high-temperature molten materials, and corrosion by corrosive substances, thus extending the service life of the steel roller body 1.

[0037] In addition, the alloy steel material of the steel roller body 1 has high strength and good wear resistance and heat resistance, which can withstand the large mechanical stress and high temperature environment during the working process, maintain a stable working state throughout the working process, ensure the normal operation and production efficiency of the equipment, and the inner wall of the installation auxiliary frame 4 is threaded to connect with the external fixing device through the thread, so that the steel roller body 1 is installed more stably in the equipment, preventing shaking or displacement during operation, and ensuring the safety and reliability of the equipment.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
