Description

Technical Field

[0001] This invention relates to the field of rolling mill auxiliary equipment technology, and specifically to a bar mill groove cooling device. Background Technology

[0002] On bar mill production lines, temperature plays a crucial role in the stability of the rolls. Poor cooling can directly reduce roll life and, in severe cases, lead to rolling accidents such as roll entanglement and breakage, causing irreparable losses to customers and workers. Therefore, forced cooling of the rolls is necessary during mill operation to prevent these unnecessary accidents. Rolls are wear-resistant consumables, so their diameter gradually changes with the number of rolling cycles. Traditional cooling water pipes only have one cooling position and cannot be adjusted in real time according to changes in roll diameter. This can result in inadequate cooling when the roll is changed from a large to a small diameter, potentially leading to rolling accidents.

[0003] For example, Chinese Patent Publication No. CN110814040A discloses the following technical solution: a three-splitting spray water pipe for a bar mill; comprising a tilting bracket and a water pipe assembly mounted on the tilting bracket; the water pipe assembly includes an inlet pipe, a connecting pipe, and splitting water pipes, with adjacent splitting water pipes connected by the connecting pipe, the outlet end of the inlet pipe inserted into the connecting pipe, the pipe body of the inlet pipe fixedly connected to the tilting bracket, and multiple downward-facing nozzles connected to the splitting water pipes; the tilting bracket includes a bracket body, which is detachably mounted on the mill crossbeam via a base; the bracket body includes a base plate fixedly connected to the base and a cover plate that mates with the base plate, the pipe body of the inlet pipe fixedly connected to the cover plate, and the cover plate being tiltably mounted above the base plate.

[0019] 1. This invention provides a bar mill groove cooling device. By setting a water-blocking device in the component, the water can be effectively blocked during the cooling process of the rolled bar. The hydraulic telescopic rod on the cover plate moves, and the hydraulic telescopic rod moves in conjunction with the roller. At the same time, the roller pushes the water-blocking plate on the adapter plate to move. The connecting spring on the fixed bar of the water-blocking plate pulls down to reset the water-blocking plate, preventing water from being reflected from the rolled steel onto the component and causing the component to rust.

[0020] 2. This invention provides a bar mill groove cooling device. By setting up a water cooling device to circulate water through the adapter plate, water is injected into the input water pipe and output through the outlet pipe in the storage tank via a corrugated pipe. This cools the bar that is in contact with the adapter plate. The device rotates with the deflector block on the connecting plate, allowing the water flow to move in coordination with the adapter plate. During the bar processing, the water dissipates excess heat from the bar, thus cooling it down.

[0021] 3. This invention provides a bar mill groove cooling device. By setting a distance adjustment device, the distance of the water cooling device is adjusted. The operation of the motor box drives the threaded rod to rotate. The nut in the fixed plate moves the threaded rod. At this time, the threaded rod pushes the sliding block to move. With the cooperation of the hinge plate and the auxiliary sliding rod, the adapter plate moves. With the cooperation of the sliding frame and the fixed block, the whole device remains stable, so that the adapter plate can fit more closely with the bar, thereby improving the cooling effect.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Example 1

[0031] like Figure 1 , 2As shown in Figures 3, 4, and 5, this invention provides a bar mill groove cooling device, including a base 1 with a groove 2 on it. A fixing plate 3 is fixedly connected to the top outer wall of the base 1, and a fixing block 4 is fixedly connected to the top outer wall of the base 1. An adapter plate 5 is provided on one side of the base 1, and a component water-blocking device 6 is provided on the adapter plate 5. The component water-blocking device 6 includes a cover plate 601, which is fixedly connected to the outer wall of the adapter plate 5. A hydraulic telescopic rod 602 is fixedly connected to the outer wall of the cover plate 601, and a roller 603 is fixedly connected to the top of the hydraulic telescopic rod 602. A roller 603 is fixedly connected to the top of the hydraulic telescopic rod 602. There is a fixing strip 604, and a connecting spring 605 is fixedly connected to the outer wall of the fixing strip 604. A water baffle 606 is hinged to the adapter plate 5 via a hinge. The water baffle 606 is fixedly connected to the connecting spring 605. A water cooling device 7 is provided on the base 1. A distance adjustment device 8 is provided on the base 1. There are two rollers 603, fixing strips 604 and connecting springs 605. The two rollers 603, fixing strips 604 and connecting springs 605 are symmetrically arranged on the adapter plate 5. By setting several rollers 603 in conjunction with fixing strips 604 and connecting springs 605, the movement of the water baffle 606 is made more stable.

[0032] In this embodiment, the water-blocking device 6 is set up to effectively block the water flow during the cooling process of the rolling bar. The hydraulic telescopic rod 602 on the cover plate 601 moves, and the hydraulic telescopic rod 602 moves in conjunction with the roller 603. At the same time, the roller 603 pushes the water-blocking plate 606 on the adapter plate 5 to move. The connecting spring 605 on the fixing bar 604 pulls down the water-blocking plate 606 to reset it, preventing water from being reflected onto the component through the rolling bar and causing the component to rust.

[0033] Example 2

[0034] like Figure 1 , 2As shown in Figure 3, based on Embodiment 1, the present invention provides a technical solution: Preferably, the water cooling device 7 includes an adapter groove 701, which is formed on the base 1. A fixing clamp 702 is fixedly connected to the outer wall of the base 1. An input water pipe 703 is fixedly connected to the fixing clamp 702.

A circular through groove is provided on the steering block 706, and the circular through groove is the same size as the connecting corrugated pipe 704. The connecting corrugated pipe 704 passes through the steering block 706 and is connected to the adapter plate 5. By setting the steering block 706, the direction of the connecting corrugated pipe 704 can be changed in conjunction with the adapter plate 5, so that the connecting corrugated pipe 704 can better carry out water conveyance operations.

[0035] In this embodiment, water is supplied to the adapter plate 5 by setting up a water cooling device 7. Water is injected into the input water pipe 703 and output through the outlet pipe 708 in the storage tank 707 via the corrugated pipe 704. This cools down the rolling bar that is in contact with the adapter plate 5 and rotates with the deflector block 706 on the connecting plate 705. This allows the water flow to move in coordination with the adapter plate 5. During the processing of the rolling bar, the water is used to dissipate excess heat from the rolling bar, thus cooling it down.

A motor housing 804 is fixedly connected to the outer wall of the sliding frame 801. The distance adjustment device 8 also includes a threaded rod 805, which is fixedly connected to the motor in the motor housing 804 via a coupling and a rotating shaft. The threaded rod 805 is threadedly connected to the nut 803 and passes through the fixed plate 3 away from the sliding frame 801. One end of 01 is rotatably connected to a sliding block 806. The sliding block 806 is slidably connected to the base 1 through a groove on the base 1. A hinge plate 807 is hinged to the sliding block 806. The hinge plate 807 is hinged to the adapter plate 5 through the hinge block. An auxiliary sliding rod 808 is fixedly connected to the connecting block 802. The auxiliary sliding rod 808 passes through the fixed plate 3 and is fixedly connected to the sliding block 806. There are two hinge plates 807. The two hinge plates 807 are symmetrically arranged on both sides of the sliding block 806, and the hinge plates 807 are adapted to the groove 2. By setting two symmetrical hinge plates 807, the hinge plates 807 can drive the adapter plate 5 to move.

[0038] In this embodiment, the distance of the water cooling device 7 is adjusted by setting the distance adjustment device 8. The operation of the motor housing 804 drives the threaded rod 805 to rotate. The nut 803 in the fixed plate 3 moves the threaded rod 805. At this time, the threaded rod 805 pushes the sliding block 806 to move. With the cooperation of the hinge plate 807 and the auxiliary sliding rod 808, the adapter plate 5 is moved. With the cooperation of the sliding frame 801 and the fixed block 4, the device as a whole remains stable, so that the adapter plate 5 can fit more closely with the rolling bar, thereby improving the cooling effect.

[0039] The working principle of a bar mill groove cooling device will be explained in detail below.

[0040] like Figure 1-6As shown, the hydraulic telescopic rod 602 on the cover plate 601 moves, and the hydraulic telescopic rod 602 moves in conjunction with the roller 603. At the same time, the roller 603 pushes the water baffle 606 on the adapter plate 5 to move. The connecting spring 605 on the fixing bar 604 pulls down the water baffle 606 to reset it, injecting water into the input water pipe 703, and outputting the water through the outlet pipe 708 in the storage tank 707 through the connecting corrugated pipe 704. This cools the rolling bar that is in contact with the adapter plate 5 and causes the rotating rod on the connecting plate 705 to cool down. The rotating block 706 allows the water flow to move in tandem with the fitting plate 5. During the processing of the rolling bar, the operation of the motor housing 804 drives the threaded rod 805 to rotate. The nut 803 in the fixed plate 3 moves the threaded rod 805, which pushes the sliding block 806 to move. With the cooperation of the hinge plate 807 and the auxiliary sliding rod 808, the fitting plate 5 moves. With the cooperation of the sliding frame 801 and the fixed block 4, the entire device remains stable, allowing the fitting plate 5 to fit more closely with the rolling bar.
