It is mainly divided into rolling guides and sliding guides. Compared with sliding guides, rolling guides can adjust the distance between the two guide wheels, but during use, the guide wheels need to fit tightly with the rolled piece for a long time to play a more powerful clamping role on the rolled piece. Therefore, if the cooling effect of the rolling guide wheel cannot keep up, accidents such as guide wheel sticking to steel, cracking, and bearing locking will frequently occur. Therefore, a device that can improve the cooling effect of the guide wheel is urgently needed. Utility Model Content

[0005] As a preferred implementation, the length of the support tube is cut according to the height of the guide wheel.

[0006] As a preferred implementation, the distance between adjacent bottom holes is 3-5 cm.

[0007] As a preferred embodiment, the distance between the spray nozzle and the guide wheel is 3-5 cm.

[0008] As a preferred embodiment, a reducing thread and a snap-on quick-connect connector are installed at the water inlet end of the three-way valve.

[0009] Compared with the prior art, the advantages and positive effects of the utility model are:

[0010] 1. When the cooling pipeline is blocked, it is easy to repair.

[0011] 2. Choose different types of spray devices according to different specifications of guide wheels, which are easy to replace and always have the best cooling effect.

[0012] 3. The inner diameter of the cooling pipeline is enlarged from the water inlet, which increases the amount of cooling water, improves the cooling effect, and reduces the frequency of steel sticking and bearing damage accidents.

[0013] 4. The cooling water spray end is changed from cylindrical to fan-shaped, which increases the cooling area of ​​the guide wheel and makes the surface temperature of the guide wheel more uniform, avoiding cracking of the guide wheel cooling layout. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1 The utility model provides a technical solution: a spray device for improving the cooling effect of the guide wheel, comprising two support tubes 1, one end of the support tube 1 is blocked, and the other end has a G1 / 2 external thread. The support tube 1 is made by cutting DN15mm stainless steel hard pipes of different lengths according to the height of the guide wheel of different specifications. A plurality of bottom holes are evenly arranged on the support tube 1, and the diameter of the bottom hole is 11.5mm. The method for setting the bottom hole is: according to the opening width of the guide wheel hole type, the center points of the spray nozzles 2 at both ends of the support tube 1 are determined, the center distance between the two points is measured, and the center distance is evenly divided according to 3-5cm in a straight line. The bottom hole of Ф11.5mm is drilled at the fixed point and the G1 / 4 thread is processed. The thread is used to install the spray nozzle 2. The spray nozzle 2 is installed in the bottom hole. The spray nozzle 2 is a fan-shaped structure, and the spray nozzle 2 forms an angle of 10-15° with the support tube 1. The top ends of the two support pipes 1 with the spray nozzles 2 installed are respectively connected to a metal hose 3, and the two metal hoses 3 are connected to a three-way valve 4 to be combined.
