Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing, and in particular to a cooling roll device for steel pipe processing. Background Technology

[0002] Cooling roll units are an important component of steel pipe processing production lines. They reduce the heat generated by the work rolls during rolling by spraying cooling water or other coolants onto them, thereby maintaining the stability of the work rolls and extending their service life. During steel pipe processing, the work rolls generate a significant amount of heat due to friction and deformation. To maintain the stability of the work rolls and extend their service life, cooling roll units are needed to cool them. Coolant is delivered to nozzles through cooling manifolds and then sprayed onto the work rolls at a specific angle and spray volume.

[0003] Existing cooling roll devices for steel pipe processing typically include a roll body, cooling nozzles, and a water tank. The water tank is usually located above the roll body, and multiple nozzles are usually installed at the bottom of the water tank. The roll body usually consists of two rolls, each with a pulley on one side. The two pulleys are connected by a belt. The steel pipe is processed by the rolls, and the nozzles cool the rolls during processing to achieve cold rolling of the steel pipe. However, in the use of existing equipment, when water impacts the rolls, it can splash out of the equipment. The splashed water may splash onto the operators or the equipment, posing a certain safety hazard. Utility Model Content

[0026] Reference Figure 1-5The present invention provides a cooling roll device for steel pipe processing, including a roll body and a cooling assembly disposed on the roll body. Isolation plates 2 are provided on opposite sides of the roll body. The two isolation plates 2 are respectively connected to the roll body through fixing assemblies. Guide plates 16 are fixedly connected to the side of the two isolation plates 2 close to the roll body. The two guide plates 16 are both arc-shaped.

[0027] The fixing assembly includes a fixing frame 5, a connecting plate 4, and a locking assembly. One side of the fixing frame 5 is fixedly connected to one side of the roll body. There are two locking assemblies. The two locking assemblies are used to fix the fixing frame 5 and the isolation plate 2. The side of the two locking assemblies away from the fixing frame 5 is fixedly connected to one side of the connecting plate 4.

[0028] Specifically, by setting up the isolation plate 2, when water from the cooling components splashes out of the equipment during use, the isolation plate 2 can block that part of the water, preventing hot water from splashing out of the equipment, ensuring the safety of the operators and reducing potential safety hazards in the use of the equipment.

[0029] By setting the guide plate 16, when the splashed water comes into contact with the isolation plate 2, due to the distance caused by gravity, this part of the water will flow back to the roll 11 with the guide plate 16, which realizes secondary cooling of the roll 11, improves the cooling efficiency of the roll 11, and extends the service life of the roll 11 to a certain extent.

[0030] By setting up the card assembly, some dirt, scale or other impurities may accumulate on the isolation plate 2 during long-term use. These will affect its isolation effect and cooling efficiency. By opening the card assembly and removing the isolation plate 2 for cleaning, the isolation plate 2 is kept in the best working condition at all times.

[0031] The locking assembly includes a locking post 15, one end of which penetrates through the fixing frame 5. A mounting hole 10 is provided on one side of the isolation plate. The end of the locking post 15 near the fixing frame 5 extends into the mounting hole 10 provided on one side of the isolation plate 2. A spring 14 is provided on the outer wall of the locking post 15 away from the mounting hole 10. One end of the spring 14 is fixedly connected to one side of the fixing frame 5, and the end of the spring 14 away from the fixing frame 5 is fixedly connected to one side of the connecting plate 4.

[0032] When it is necessary to disassemble the fixed frame 5 and the isolation plate 2, the connecting plate 4 can be pulled away from the fixed frame 5. The movement of the connecting plate 4 drives the locking column 15 to move, so that the locking column 15 can be disengaged from the mounting hole 10. At this time, the separation and disassembly of the fixed frame 5 and the isolation plate 2 can be achieved.

[0033] When it is necessary to install the fixed frame 5 and the isolation plate 2, pull the connecting plate 4 again. During this process, the movement of the connecting plate 4 will stretch the spring 14, put the bottom of the isolation plate 2 into the interior of the fixed frame 5, and then release the connecting plate 4. The connecting plate 4 will be reset due to the movement of the spring 14, so that the locking post 15 re-enters the interior of the mounting hole 10, and completes the connection and installation between the isolation plate 2 and the fixed frame 5.

[0034] The main body of the rolling mill includes a rolling mill 11, a support frame 1, and a drive assembly. Two rolling mill 11s are provided, both installed inside the support frame 1. The drive assembly is used to synchronously drive the two rolling mill 11s. The drive assembly includes pulleys 8, a motor 6, and a support plate 9. Two pulleys 8 are provided, each installed on one side of one of the two rolling mill 11s and connected by a belt 7. The output end of the motor 6 is connected to one side of one of the pulleys 8. The motor 6 is fixedly mounted on the support plate 9, and one side of the support plate 9 is fixedly connected to one side of the support frame 1. The cooling assembly includes a water tank 12 and a nozzle 13. The water tank 12 is installed inside the support frame 1, and the nozzle 13 is installed at the bottom of the water tank 12. The rolling mill 11 is used to process the steel pipe, and during processing, the nozzle 13 cools the rolling mill 11, achieving cold rolling of the steel pipe.

[0035] A through groove 3 is provided on one side of the isolation plate 2. The through groove 3 is designed to ensure that the sensor can smoothly enter the interior of the equipment.

[0036] A water receiving frame 17 is provided at the bottom of the support frame, and a filter screen 23 is provided at the upper end of the water receiving frame 17. A handle 22 is fixedly connected to the upper end of the filter screen 23, and an installation block 21 is fixedly connected to the opposite side of the filter screen 23. The two installation blocks 21 extend into the installation groove provided on the water receiving frame 17. A lower connecting pipe 18 is connected to one side of the water receiving frame 17. A water pump 19 is fixedly provided at the end of the lower connecting pipe 18 away from the water receiving frame 17. One side of the water pump 19 is fixedly connected to one side of the support frame 1. An upper connecting pipe 20 is fixedly connected at the end of the water pump 19 away from the lower connecting pipe 18. The end of the upper connecting pipe 20 away from the water pump is connected to the water tank 12.

[0037] Specifically, after the water passes through the two rollers 11, it will eventually fall into the water receiving frame 17 due to gravity. The filter screen 23 installed inside the water receiving frame 17 will filter this part of the water. The filtered water will eventually enter the water receiving frame 17. The water pump 19 can then re-input the filtered water into the water tank 12, completing the overall water circulation process and reducing water waste.

[0038] The filter screen 23 can be detached from the water receiving frame 17 by pulling the handle 22, making it easy to clean the filter screen 23.

[0039] Working principle: When the device is in use, when it is necessary to disassemble the fixed frame 5 and the isolation plate 2, the connecting plate 4 can be pulled away from the fixed frame 5. The movement of the connecting plate 4 drives the locking column 15 to move, so that the locking column 15 can be disengaged from the mounting hole 10. At this time, the separation and disassembly of the fixed frame 5 and the isolation plate 2 can be achieved.

[0040] When it is necessary to install the fixed frame 5 and the isolation plate 2, pull the connecting plate 4 again. During this process, the movement of the connecting plate 4 will stretch the spring 14, put the bottom of the isolation plate 2 into the interior of the fixed frame 5, and then release the connecting plate 4. The connecting plate 4 will be reset due to the movement of the spring 14, so that the locking post 15 re-enters the interior of the mounting hole 10, and completes the connection and installation between the isolation plate 2 and the fixed frame 5.

[0041] By setting up the isolation plate 2, when water from the cooling components splashes out of the equipment during use, the isolation plate 2 can block the water from splashing out of the equipment, thus ensuring the safety of the operators and reducing potential safety hazards in the use of the equipment.

[0042] By setting the guide plate 16, when splashed water comes into contact with the isolation plate 2, due to gravity moving away, this part of the water will flow back to the roll 11 with the guide plate 16, which realizes secondary cooling of the roll 11, improves the cooling efficiency of the roll 11, and extends the service life of the roll 11 to a certain extent.
