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 rolls are crucial components on rolling mills used for rolling metals. They endure immense pressure and wear during the rolling process. The development of steel roll technology is closely related to the progress of the metallurgical industry. With continuous innovation in rolling technology, the materials, manufacturing processes, and application technologies of steel rolls are also constantly improving. Steel roll manufacturing technologies are mainly divided into two categories: casting and forging. Cast steel rolls are formed by directly pouring molten metal into shape, while forged steel rolls are shaped using a forging process. During the manufacturing process, the selection of steel roll materials, heat treatment processes, and surface treatment technologies all have a significant impact on the performance of the steel rolls.

[0003] Traditional steel roller connection methods may require more complex tools or steps, and problems such as wear, deformation, and fatigue may occur during use. Therefore, those skilled in the art have provided a novel composite steel roller to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel composite steel roller. This roller achieves rapid connection and disassembly through a combination of a locking block on the central shaft and a sliding groove on the inner wall of the outer steel roller. This design not only ensures the stability of the connection but also facilitates maintenance and component replacement. Traditional steel roller connection methods may require more complex tools or steps, while this design allows for connection and disassembly through simple rotation and sliding movements, greatly improving operational convenience and efficiency. Through multiple protective measures including a protective layer, rubber layer, support plate, elastic layer, and protective shell, this multi-layered protection design effectively prevents wear, corrosion, and external impacts, while also reducing vibration and noise, and improving the service life and operational stability of the steel roller. The elastic layer, made of silicone, possesses excellent elasticity and flexibility, effectively absorbing and dispersing impact forces to protect the steel roller from damage. The protective shell, made of stainless steel, offers high strength, corrosion resistance, and wear resistance, providing a robust outer layer of protection against harsh working environments and physical collisions. This optimized material selection not only enhances product performance but also extends its service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel composite steel roller, comprising a central shaft, connecting shafts at the center of both sides of the central shaft, four connecting blocks arranged in a ring at one side of the center of the outer sides of the two connecting shafts, an outer steel roller sleeved at the center of the outer side of the central shaft, a connecting structure on the inner side of the outer steel roller, a protective structure sleeved on the outer side of the outer steel roller, multiple support plates arranged in a ring on the outer side of the protective structure, and an elastic protective structure sleeved on the outer side of the multiple support plates;

[0006] Through the above technical solution, the steel rollers are quickly connected and disassembled by combining the locking block on the central shaft with the sliding groove on the inner side wall of the outer steel roller. This design not only ensures the stability of the connection but also facilitates maintenance and component replacement. Traditional steel roller connection methods may require more complex tools or steps, while this design can complete the connection and disassembly with simple rotation and sliding actions, greatly improving the convenience and efficiency of operation. Through multiple protective measures such as a protective layer, rubber layer, support plate, elastic layer, and protective shell, this multi-layered protection design can not only effectively prevent wear, corrosion, and external impacts but also reduce vibration and noise, improving the service life and working stability of the steel rollers. The elastic layer is made of silicone, which has excellent elasticity and flexibility, effectively absorbing and dispersing impact forces to protect the steel rollers from damage. The protective shell is made of stainless steel, whose high strength, corrosion resistance, and wear resistance provide a robust outer layer of protection for the steel rollers, resisting harsh working environments and physical collisions. This optimized material selection not only improves product performance but also extends its service life.

[0007] Furthermore, the connecting structure includes four sliding grooves and eight locking blocks. The four sliding grooves are arranged in a ring on the inner side wall of the outer steel rod, and the eight locking blocks are arranged in groups of four. The two groups of locking blocks are arranged in a ring on both sides of the center of the outer side wall of the central axis.

[0008] The above technical solution involves first fitting the outer steel rod onto the central shaft, adjusting its position to align the locking block on the central shaft with the sliding groove on the inner wall of the outer steel rod, then pushing the outer steel rod to allow the locking block to slide smoothly into the sliding groove. Once the locking block has completely passed through the sliding groove, rotating the central shaft causes the locking block and the sliding groove to misalign in the circumferential direction, thus preventing the outer steel rod from separating from the central shaft in the axial direction and achieving the connection between the two. If it is necessary to disassemble the outer steel rod, simply reverse the operation: first rotate the central shaft to align the locking block with the sliding groove, and then push the outer steel rod out axially, facilitating maintenance and component replacement.

[0009] Furthermore, the protective structure includes a protective layer and a rubber layer. The protective layer is sleeved on the outer wall of the outer steel rod, and the rubber layer is sleeved on the outer wall of the protective layer. A plurality of the support plates are arranged in a ring on the outer wall of the rubber layer.

[0010] Through the above technical solution, the protective layer provides the first layer of protection for the outer steel rod, and the rubber layer further enhances the protective effect. When the outer steel rod is in operation, the protective layer can prevent the outer steel rod from directly contacting external objects and being damaged by wear, corrosion and other damage. The rubber layer has a certain elasticity and buffering effect, which can reduce the impact of external impact on the outer steel rod, and at the same time reduce the vibration and noise generated by the outer steel rod during operation. Multiple support plates provide support and stability for the entire structure, ensuring that the outer steel rod can maintain the correct position and posture during operation.

[0011] Furthermore, the elastic protective structure includes an elastic layer and a protective shell, wherein the elastic layer is sleeved on the outer wall of a plurality of support plates, and the protective shell is sleeved on the outer wall of the elastic layer;

[0012] Through the above technical solution, the elastic layer is sleeved on the outer wall of multiple support plates. When the outer steel rod is impacted by external force during operation, the elastic layer can undergo elastic deformation to absorb and buffer part of the impact force, reducing the damage of the impact force to the internal structure of the outer steel rod and the support plates. The protective shell is sleeved on the outer wall of the elastic layer, providing the outermost protection for the entire outer steel rod structure, preventing external dust, moisture, impurities and other contaminants from entering the interior of the outer steel rod, and at the same time, it can resist external physical collisions to a certain extent.

[0013] Furthermore, the four grooves are respectively adapted to the four locking blocks;

[0014] The above technical solutions make the installation process more accurate and reliable, reducing the possibility of installation errors.

[0015] Furthermore, the elastic layer is made of silicone.

[0016] Through the above technical solution, silicone has good elasticity and flexibility. When the outer steel rod is impacted by external force, the elastic layer of silicone material can quickly deform to absorb and disperse the impact force.

[0017] Furthermore, the protective shell is made of stainless steel;

[0018] Through the above technical solutions, stainless steel has the characteristics of high strength, corrosion resistance, and wear resistance. The protective shell is made of stainless steel, which can effectively resist external physical impact, chemical corrosion and wear.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, the new composite steel roller is connected and disassembled quickly by combining the locking block on the central shaft with the sliding groove on the inner side wall of the outer steel roller. This design not only ensures the stability of the connection, but also facilitates maintenance and replacement of parts. Traditional steel roller connection methods may require more complicated tools or steps, while this design can complete the connection and disassembly through simple rotation and sliding actions, which greatly improves the convenience and efficiency of operation.

[0021] 2. In this utility model, through multiple protective measures such as protective layer, rubber layer, support plate, elastic layer and protective shell, this multi-layered protection design can not only effectively prevent wear, corrosion and external impact, but also reduce vibration and noise, and improve the service life and working stability of the steel roller.

[0022] 3. In this utility model, the elastic layer is made of silicone, which has excellent elasticity and flexibility, and can effectively absorb and disperse impact force to protect the steel roller from damage. The protective shell is made of stainless steel, which has high strength, corrosion resistance and wear resistance, providing a solid outer layer protection for the steel roller and resisting harsh working environments and physical collisions. This optimized choice of material not only improves the performance of the product, but also extends its service life. Attached Figure Description

First, the outer steel rod 5 is placed on the central shaft 1. The position is adjusted so that the locking blocks 402 on the central shaft 1 are aligned with the sliding grooves 401 on the inner wall of the outer steel rod 5. Then, the outer steel rod 5 is pushed so that the locking blocks 402 slide smoothly into the sliding grooves 401. When the locking blocks 402 have completely passed through the sliding grooves... After step 401, rotate the central shaft 1 to make the locking block 402 and the slide groove 401 misaligned in the circumferential direction, thereby preventing the outer steel rod 5 from separating from the central shaft 1 in the axial direction and realizing the connection between the two. If it is necessary to disassemble the outer steel rod 5, simply reverse the operation: first rotate the central shaft 1 to align the locking block 402 with the slide groove 401, and then push the outer steel rod 5 out axially. This facilitates maintenance and replacement of parts.

The elastic layer 801 is fitted onto the outer walls of multiple support plates 7, and the protective shell 802 is fitted onto the outer walls of the elastic layer 801. When the outer steel rod 5 is impacted by external forces during operation, the elastic layer 801 can undergo elastic deformation to absorb and buffer part of the impact force, reducing the damage to the internal structure of the outer steel rod 5 and the support plates 7. The protective shell 802, fitted onto the outer walls of the elastic layer 801, provides the outermost protective shell for the entire outer steel rod 5 structure. The outer steel rod 5 is protected by a layer of material to prevent dust, moisture, impurities and other external contaminants from entering. It can also resist external physical impacts to a certain extent. The elastic layer 801 is made of silicone, which has good elasticity and flexibility. When the outer steel rod 5 is impacted by external force, the elastic layer 801 made of silicone can quickly deform to absorb and disperse the impact force. The protective shell 802 is made of stainless steel, which has high strength, corrosion resistance and wear resistance. The protective shell 802 is made of stainless steel, which can effectively resist external physical impacts, chemical corrosion and wear.

[0034] Working principle: The central shaft 1, as the core support component of the entire steel roller, provides the installation foundation and stable central shaft line for the outer steel roller 5 and other structures. The connecting shaft 2 is used to connect the outer steel roller 5 to external equipment, transmit power or support the operation of the steel roller. The connecting block 3 cooperates with the connecting structure 4 on the inner side wall of the outer steel roller 5 to achieve a firm connection between the central shaft 1 and the outer steel roller 5. The outer steel roller 5 is fitted onto the central shaft 1, and the position is adjusted so that the locking block 402 on the central shaft 1 is aligned with the sliding groove 401 on the inner side wall of the outer steel roller 5. Push the outer steel rod 5 so that the locking block 402 can slide smoothly into the slide groove 401. After the locking block 402 has completely passed through the slide groove 401, rotate the central shaft 1 so that the locking block 402 and the slide groove 401 are misaligned in the circumferential direction, thereby preventing the outer steel rod 5 from separating from the central shaft 1 in the axial direction and realizing the connection between the two. If it is necessary to disassemble the outer steel rod 5, simply reverse the operation: first rotate the central shaft 1 to align the locking block 402 with the slide groove 401, and then push the outer steel rod 5 out in the axial direction, which is convenient for maintenance and replacement of parts.
