Description

Technical Field

[0001] This utility model relates to the field of roll cooling technology, and in particular to a roll cooling device with adjustable distance. Background Technology

[0002] The cooling devices commonly used in steel rolling mill rolls are all integral structures, mainly consisting of a fixing device, an arc-shaped cooling nozzle, and a connecting structure between the two. While the connecting structure is fixed, the roll diameter decreases with processing and grinding, causing changes in the distance between the cooling device and the roll. When the cooling device is too far from the roll surface, the cooling effect is affected, leading to overheating of the roll groove surface, causing blackening and wear, and potentially even surface chipping and roll breakage. Therefore, this invention proposes an adjustable-distance roll cooling device to address the shortcomings of existing technologies. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide an adjustable distance roll cooling device. This device involves setting a first adjustment groove on a first connecting plate and a second adjustment groove on a second connecting plate, with fastening bolts and nuts connecting the first and second connecting plates within the first adjustment groove. When the roll diameter decreases due to wear, the installation position of the second connecting plate on the first connecting plate is moved to adjust the arc-shaped cooling mounting seat closer to the roll, maintaining a constant distance between the cooling nozzles on the arc-shaped cooling mounting seat and the outer wall of the roll.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An adjustable-distance roll cooling device includes an arc-shaped cooling mounting base, an adjustable connector, and a fixed slot seat. The arc-shaped cooling mounting base has an arc-shaped plate on its inner side, a groove on the arc-shaped plate, and a cooling nozzle within the groove. A cooling main pipe is located inside the arc-shaped cooling mounting base, and the cooling nozzle is connected to the cooling main pipe. The adjustable connector includes a first connecting plate and a second connecting plate. The first connecting plate is fixed to a mounting base via the fixed slot seat. The second connecting plate is disposed on the outer wall of the arc-shaped cooling mounting base. The first connecting plate has a first adjustment groove, and the second connecting plate has a second adjustment groove. A fastening bolt is located within the first adjustment groove, and one end of the fastening bolt passes through the second adjustment groove and is connected to a nut.

[0006] A further improvement is that a water inlet pipe is provided on the upper side wall of the arc-shaped cooling mounting base, and one end of the water inlet pipe is connected to the main cooling pipe.

[0007] A further improvement is that the fixed card slot is provided with an installation groove, and one end of the first connecting plate is detachably installed in the installation groove.

[0008] A further improvement is that: a locking bolt is provided on the fixing slot seat at the mounting groove, a locking hole is provided on the first connecting plate, and multiple locking holes are provided. A mating hole adapted to the locking hole is provided on the inner wall of the mounting groove, and one end of the locking bolt passes through the locking hole and connects with the mating hole.

[0009] A further improvement is that the second connecting plate is provided with a T-shaped slider, the first connecting plate is provided with a T-shaped groove, and the second connecting plate is slidably connected to the T-shaped slider and the T-shaped groove.

[0010] A further improvement is that a lever is provided at the top of the end of the second connecting plate away from the arc-shaped cooling mounting base.

[0011] A further improvement is that both the first adjustment groove and the second adjustment groove are inclined, and the first adjustment groove and the second adjustment groove have the same size.

[0012] The beneficial effects of this utility model are as follows: This utility model sets the adjustable connecting part of the connecting arc-shaped cooling mounting base and the fixed slot base to be composed of a first connecting plate and a second connecting plate. A first adjustment groove is set on the first connecting plate, a second adjustment groove is set on the second connecting plate, and a fastening bolt and nut are set in the first adjustment groove to connect the first connecting plate and the second connecting plate. When the roll diameter decreases due to wear, the installation position of the second connecting plate on the first connecting plate is moved to adjust the arc-shaped cooling mounting base closer to the roll, keeping the distance between the cooling nozzle on the arc-shaped cooling mounting base and the outer wall of the roll constant. This allows the cooling device to perform cooling operations stably and efficiently, thereby improving the service life of the roll. Attached Figure Description
