Description

Technical Field

[0001] This invention relates to the field of energy-saving equipment technology, specifically to a drive transmission component and method for hot rolling of seamless steel pipes. Background Technology

[0002] In the field of seamless steel pipe production, hot rolling is a key process that determines product performance and production efficiency. As the power core of the rolling equipment, the drive transmission component directly undertakes the important task of converting motor energy into the rotation and linear propulsion force of the rolls. However, in actual operation, the drive transmission component faces the problem of reduced lubrication. Once the lubrication effect is poor, the friction between the components inside the component will increase significantly, and the wear will also intensify. This energy loss caused by friction and sliding will directly lead to a reduction in the transmission efficiency of the drive transmission component, making it impossible to fully and effectively transfer the motor energy to the rolls, thereby affecting the normal operation of the rolls.

[0003] Referring to the patent application with publication number CN206997358U, a main drive structure for a multi-metal cold composite rolling mill with four rolls individually driven is disclosed. By setting up a main drive arrangement structure with four rolls individually driven, it can not only meet the rolling torque of the support rolls, but also solve the problem of slippage of the work rolls during the rolling process. In addition, the structure is simple, reliable and convenient for daily maintenance.

[0004] A comprehensive analysis of the above-mentioned patents reveals the following shortcomings: Existing drive transmission components and methods for hot rolling of seamless steel pipes typically require additional power to periodically add lubricating oil to the components to ensure stable transmission during long-term use, resulting in high energy consumption. Furthermore, it is difficult to utilize the heat from the high-temperature seamless steel pipe itself to trigger automatic lubrication and effectively filter the lubricating oil. Therefore, it is necessary to provide a drive transmission component and method for hot rolling of seamless steel pipes to solve the aforementioned technical problems. Summary of the Invention

[0015] This invention also provides a method for using a drive transmission assembly for hot rolling of seamless steel pipes. The method includes the following steps: Step 1: Start the energy-saving drive mechanism to drive the heat conduction frame mechanism and the transmission roller to rotate. The rotating transmission roller is used to transmit the high temperature seamless steel pipe in the hot rolling process. When a high temperature seamless steel pipe passes the surface of the heat conduction frame mechanism, the heat of the high temperature seamless steel pipe is transferred to the functional cylinder mechanism and the transmission frame mechanism through the heat conduction frame mechanism. Step 2: As the temperature rises, the functional cylinder mechanism gradually squeezes out the lubricating oil from the upper part of the inner cavity, squeezing it into the placement box and dripping onto the heat conduction frame mechanism. As the heat conduction frame mechanism rotates, the lubricating oil comes into contact with the energy-saving drive mechanism, lubricating the meshing parts of the energy-saving drive mechanism and the heat conduction frame mechanism. The lubricating oil that flows to the bottom of the placement box eventually flows into the lubricating oil collection mechanism. At the same time, the transmission frame mechanism gradually approaches the energy-saving drive mechanism and eventually comes into contact with it. As the energy-saving drive mechanism rotates, friction drives the transmission frame mechanism to rotate. The rotating transmission frame mechanism drives the lubricating oil collection mechanism to work, enabling the lubricating oil collection mechanism to self-clean and prevent blockage. Step 3: When no high-temperature seamless steel pipe passes over the top of the drive roller, as the temperature decreases, the drive frame mechanism gradually moves away from the energy-saving drive mechanism. During the rotation of the energy-saving drive mechanism, it no longer drives the drive frame mechanism to rotate, thereby stopping the self-cleaning operation of the lubricating oil collection mechanism. At the same time, the internal suction force of the functional cylinder mechanism gradually draws the filtered lubricating oil in the lubricating oil collection mechanism into the functional cylinder mechanism. So that when the high-temperature seamless steel pipe passes over the drive roller again, as the temperature rises, the functional cylinder mechanism will automatically add lubricating oil to the meshing part of the energy-saving drive mechanism and the heat conduction frame mechanism for lubrication. Beneficial effects

[0016] This invention provides a drive transmission assembly and method for hot rolling of seamless steel pipes. Compared with the prior art, it has the following advantages: 1. A drive transmission assembly and method for hot rolling of seamless steel pipes, comprising an energy-saving drive mechanism, a heat conduction frame mechanism, a functional cylinder mechanism, a transmission frame mechanism, a lubricating oil collection mechanism, and a transmission roll, wherein when a high-temperature seamless steel pipe passes over the top of the transmission roll, the heat of the high-temperature seamless steel pipe is transferred to the functional cylinder mechanism and the transmission frame mechanism through the heat conduction frame mechanism. As the temperature rises, the functional cylinder mechanism automatically adds lubricating oil to the meshing parts of the energy-saving drive mechanism and the heat conduction frame mechanism for lubrication. This automated lubrication operation not only significantly reduces frictional loss on the meshing surface and reduces additional energy consumption caused by friction, further highlighting the high efficiency and energy saving characteristics, but also effectively extends the service life of the mechanism. At the same time, the transmission frame mechanism is gradually driven until it rotates to drive the lubricating oil collection mechanism to work, enabling the lubricating oil collection mechanism to perform self-cleaning and prevent clogging, so that the lubricating oil can be properly filtered afterwards, thereby maintaining the stability of the lubrication effect of the entire transmission system and achieving a perfect integration of high efficiency and energy saving and stable operation.

[0017] 2. A drive transmission assembly and method for hot rolling of seamless steel pipes, comprising a pinion, an energy-saving motor, a heat-conducting sleeve, a heat-conducting rod, a second heat-conducting plate, a large gear, a functional cylinder mechanism, and a transmission frame mechanism, wherein when the high-temperature seamless steel pipe comes into contact with the heat-conducting sleeve, the heat of the seamless steel pipe is transferred to the heat-conducting rod and the second heat-conducting plate through the heat-conducting sleeve and the first heat-conducting plate. Then the heat-conducting rod transfers the heat to the mercury in the functional cylinder mechanism, and the second heat-conducting plate transfers the heat to the mercury in the transmission frame mechanism. The thermal expansion characteristics of the mercury trigger subsequent actions, achieving precise heat transfer and efficient utilization. This design eliminates the need for an additional power mechanism, ensuring timely and automatic lubrication and self-cleaning, thereby improving energy utilization.

[0018] 3. A drive transmission assembly and method for hot rolling of seamless steel pipes, wherein the heat-conducting rod transfers heat to the mercury in the cylinder through the cooperation of the cylinder, piston rod, piston one, mercury, and heat-conducting rod. The mercury expands when heated and pushes the lower piston one upward, and the upper piston one moves upward accordingly. During the process, the lubricating oil in the cylinder and located at the top of the upper piston one is squeezed out through the oil outlet pipe and squeezed to the top of the large gear. With the meshing rotation of the large gear and the small gear, the lubricating oil naturally diffuses to the meshing surface of the two gears, effectively reducing friction loss and extending the service life of the gears, thereby ensuring the long-term stable and efficient operation of the transmission system driven by the energy-saving motor.

[0019] 4. A drive transmission assembly and method for hot rolling of seamless steel pipes, comprising a heat-conducting bent rod, a second piston, a second friction cone disk, a first spring, a cam, a push plate, a second spring, a brush, and a filter screen, wherein the heat-conducting disk transfers heat to mercury in a hollow cylinder through the heat-conducting contact block and the heat-conducting bent rod. The mercury expands upon heating and pushes the second piston to the right, thereby pushing the second friction cone disk to the right, causing the upper sidewall of the second friction cone disk to contact the lower sidewall of the first friction cone disk. As the first friction cone disk rotates, friction drives the second friction cone disk to rotate as well. The drive shaft and cam rotate accordingly. The rotating cam, in conjunction with the second spring, causes the push plate to move up and down reciprocally, and the brush moves up and down reciprocally, automatically cleaning the filter screen. The entire process requires no manual intervention, relying solely on the heat of the steel pipe itself to trigger the cleaning, effectively preventing impurities in the lubricating oil from clogging the system and ensuring the cleanliness of the circulating lubricating oil.

[0027] Through the coordinated operation of the small gear 32, energy-saving motor 34, heat-conducting sleeve 41, heat-conducting rod 43, heat-conducting plate 44, large gear 46, functional cylinder mechanism 6, and transmission frame mechanism 7, when the high-temperature seamless steel pipe comes into contact with the heat-conducting sleeve 41, the heat from the seamless steel pipe is transferred through the heat-conducting sleeve 41 and heat-conducting plate 42 to the heat-conducting rod 43 and heat-conducting plate 44. Then, the heat-conducting rod 43 transfers the heat to the mercury in the functional cylinder mechanism 6, and the heat-conducting plate 44 transfers the heat to the mercury in the transmission frame mechanism 7. The thermal expansion properties of mercury trigger subsequent actions, achieving precise heat transfer and... This highly efficient design eliminates the need for an additional power mechanism, ensuring timely and automatic lubrication and self-cleaning, thus improving energy utilization. Through the interaction of the cylinder 61, piston rod 63, piston 64, mercury, and heat-conducting rod 43, the heat-conducting rod 43 transfers heat to the mercury in the cylinder 61. The heated mercury expands and pushes the lower piston 64 upwards, causing the upper piston 64 to move upwards as well. During this process, the lubricating oil inside the cylinder 61, located at the top of the upper piston 64, is squeezed out through the oil outlet pipe 66 and directed towards the top of the large gear 46. The meshing of the large gear 46 and the small gear 32 further facilitates this process. Rotation allows the lubricating oil to naturally diffuse to the meshing surfaces of the two gears, effectively reducing friction loss and extending gear life. This ensures the long-term stable and efficient operation of the transmission system driven by the energy-saving motor 34. Through the cooperation of the heat-conducting bent rod 710, piston 78, second friction cone disc 74, first spring 76, cam 72, push plate, second spring 86, brush 87, and filter screen 82, the heat-conducting disc 44 transfers heat to the mercury in the hollow cylinder 77 through the heat-conducting contact block 711 and heat-conducting bent rod 710. After being heated and expanding, the mercury pushes the piston 78 to the right, thereby pushing the second friction cone disc 74. The friction cone 74 moves to the right, so that the upper sidewall of the second friction cone 74 contacts the lower sidewall of the first friction cone 33. As the first friction cone 33 rotates, the friction force drives the second friction cone 74 to rotate together. The transmission shaft 71 and cam 72 rotate accordingly. The rotating cam 72 cooperates with the second spring 86 to make the push plate move up and down reciprocally. The brush 87 moves up and down reciprocally accordingly to automatically clean the filter screen 82. No manual intervention is required throughout the process. It is triggered only by the heat of the steel pipe itself, which effectively prevents impurities in the lubricating oil from clogging the 82 and ensures the cleanliness of the circulating lubricating oil.

[0028] This invention also provides a method for using a drive transmission assembly for hot rolling of seamless steel pipes. The method includes the following steps: Step 1: Start the energy-saving motor 34. The horizontal shaft 31, the pinion 32 and the first friction cone disk 33 rotate. Since the pinion 32 meshes with the large gear 46, the large gear 46, the right rotating shaft 45, the second heat-conducting disk 44, the heat-conducting sleeve 41 and the transmission roller 9 rotate accordingly. The rotating transmission roller 9 is used to transmit the high-temperature seamless steel pipe in the hot rolling process. When a high-temperature seamless steel pipe passes the surface of the heat-conducting sleeve 41, the heat of the high-temperature seamless steel pipe is transferred to the heat-conducting rod 43 and the second heat-conducting disk 44 through the heat-conducting sleeve 41 and the first heat-conducting disk 42. Then the heat-conducting rod 43 transfers the heat to the mercury in the functional cylinder mechanism 6, and the second heat-conducting disk 44 transfers the heat to the mercury in the transmission frame mechanism 7. Step 2: As the temperature rises, the heat-conducting rod 43 transfers heat to the mercury in the cylinder 61. The mercury expands due to heat, pushing the lower piston 64 upwards. The upper piston 64 moves upwards accordingly, squeezing the lubricating oil inside the cylinder 61 and located at the top of the upper piston 64 through the oil outlet 66. This oil is then forced towards the top of the large gear 46. The meshing rotation of the large gear 46 and the small gear 32 allows the lubricating oil to naturally diffuse to the meshing surfaces of the two gears, effectively reducing friction loss and extending gear life. The lubricating oil that flows to the bottom of the inner cavity of the placement box 2 eventually flows back into the collection box 81 through the oil drain. Simultaneously, the transmission frame mechanism 7 gradually approaches the energy-saving drive mechanism 3. During this process, the heat-conducting plate 44 transfers heat through the heat-conducting contact block 7. The mercury in the hollow cylinder 77 is transferred to the heat-conducting bent rod 710. After the mercury expands due to heat, it pushes the piston 78 to the right, thereby pushing the second friction cone disk 74 to the right. The first spring 76 is compressed, so that the upper side wall of the second friction cone disk 74 contacts the lower side wall of the first friction cone disk 33. As the first friction cone disk 33 rotates, the friction force can drive the second friction cone disk 74 to rotate together. The transmission shaft 71 and cam 72 rotate accordingly. The rotating cam 72 cooperates with the second spring 86 to make the push plate move up and down reciprocally. The brush 87 moves up and down reciprocally accordingly to automatically clean the filter screen plate 82, effectively preventing impurities in the lubricating oil from clogging the filter screen plate 82 and ensuring the cleanliness of the circulating lubricating oil. Step 3: When no high-temperature seamless steel pipe passes over the top of the transmission roller 9, as the temperature decreases, the mercury in the hollow cylinder 77 contracts. Under the elastic action of the first spring 76, the second friction cone disk 74 gradually returns to its original position and separates from the first friction cone disk 33, preventing the brush 87 from constantly cleaning the filter screen 82 and reducing the wear of the brush 87. At the same time, the mercury in the cylinder 61 also contracts. Under the action of the weight of the piston rod 63 and piston 64, piston 64 moves with the mercury... As the upper piston 64 moves downward, the inner cavity of the cylinder 61, located above the upper piston 64, generates a suction force. Through the oil inlet pipe 65 and each branch pipe 83, the lubricating oil in the collection box 81 is drawn into the cylinder 61. This ensures that when the high-temperature seamless steel pipe passes through the transmission roller 9 again, as the temperature rises, the functional cylinder mechanism 6 will automatically apply lubricating oil to the meshing parts of the energy-saving drive mechanism 3 and the heat conduction frame mechanism 4 to reduce energy consumption during the drive process.
