Description

Technical Field

[0001] This utility model relates to the field of finishing mill equipment technology, and in particular to an anti-loosening mechanism for the lead screw of the finishing mill roll box. Background Technology

[0002] The finishing mill roll box is a key component of the finishing mill. It consists of roll bearing housings, axial and radial adjustment devices, and a lubrication system. It is used to install and support the rolls, and can precisely adjust the position and gap of the rolls to ensure that the rolled material can achieve the required thickness accuracy and good surface quality during the rolling process, thereby guaranteeing product quality and improving production efficiency.

[0003] When it is necessary to adjust the roll gap, position the rolls, and balance the axial force, the lead screw is used in the finishing mill roll box. The lead screw is a transmission element in the finishing mill roll box components, consisting of a lead screw shaft and a nut. The lead screw shaft is a slender shaft with threads, which are high-precision trapezoidal threads or ball threads. The nut is connected to the roll adjustment mechanism inside the roll box.

[0004] The finishing mill generates significant vibration and impact during operation, which can cause the lead screw to loosen easily. Loosening of the lead screw in the finishing mill roll box can lead to problems such as unstable roll gap, roll vibration, and reduced roll positioning accuracy. This results in products that do not meet quality standards, affecting their appearance and reducing their added value. Once loosened, the machine needs to be stopped for inspection and repair, which seriously affects production efficiency. The additional maintenance costs also increase production costs.

The bottoms of the two hydraulic rods 8 are fixedly connected to the top of the slide rod 5. Multiple limiting holes 9 are equidistantly provided on the lower front side of the outer casing 3 and the front side of the slide rod 5 to control the distance between the clamping arc plates 7. Bolts 10 are threaded inside the multiple limiting holes 9 to fix the clamping arc plates 7. Rollers 11 are rotatably connected to the bottom right side of the roller box housing 1 for rolling. A lead screw component 12 is rotatably connected to the front side of the roller box housing 1 to adjust the gap of the rollers 11. A lubrication mechanism 2 is provided inside the roller box housing 1 to lubricate the lead screw component 12 to improve the service life of the equipment.

[0034] Reference Figure 2 and Figure 5The lubrication mechanism 2 includes an oil tank 201, the bottom of which is fixedly connected to the top left side of the roller box housing 1 for storing lubricating oil. A water pump 202 is connected to the upper right side of the oil tank 201 to control the flow rate of the lubricating oil. A hose 203 is connected to the right end of the water pump 202 for guiding the flow. A discharge rod 204 is fixedly connected to the right end of the hose 203 to increase the discharge area. Discharge holes 205 are evenly spaced at the bottom of the discharge rod 204 for the lubricating oil to flow out. A slider 206 is fixedly connected to the rear end of 204 to drive the liquid outlet rod 204 to slide up and down. A motor 208 is fixedly connected to the rear side of the roller box housing 1 to provide power. The output end of the motor 208 passes through the outer wall of the roller box housing 1 and is rotatably connected to a half gear 207. Rotation drives the slider 206 to move up and down. The half gear 207 is rotatably connected inside the slider 206. A sponge 209 is fixedly connected to the bottom of the liquid outlet rod 204 to contact the lead screw component 12 for lubrication.

[0035] Reference Figure 3 and Figure 4 Multiple rubber pads 13 are fixedly connected to the inner sides of multiple clamping arc plates 7. These rubber pads 13 are all arc-shaped to increase friction. An inlet 14 is provided on the top front side of the oil tank 201 for adding lubricating oil. A pipe 15 is fixedly connected inside the inlet 14; its regular shape helps to increase the sealing of the oil tank 201. A lamp holder 16 is fixedly connected to the top front side of the roller box housing 1 to support the lamp. A lighting lamp 17 is rotatably connected to the top of the lamp holder 16 for illumination.

[0036] Reference Figure 1 , Figure 3 and Figure 4 A frame 18 is fixedly connected to the left side of the roller box housing 1 for fixing a reflector 19. The reflector 19 is also fixedly connected to the left side of the frame 18 to warn of safety. A control panel 20 is fixedly connected to the front of the roller box housing 1 for issuing commands. Multiple buttons 21 are equidistantly slidably connected to the front of the control panel 20 for operation. A vibration sensor 22 is fixedly connected to the lower rear part of the roller box housing 1. The vibration sensor 22 is electrically connected to the control panel 20 to monitor vibration.

[0037] Working principle: When using the anti-loosening mechanism of the screw of the finishing mill roll box, depending on the thickness of the screw component 12, the clamping arc plate 7 is manually slid left and right inside the second groove 6. When the bottom clamping arc plate 7 is tightly attached to the screw component 12 on both sides, the top clamping arc plate 7 is adjusted to the same distance. Then, the clamping arc plate 7 is fixed by bolts 10 through the corresponding limit holes 9. The screw component 12 can be fixed left and right. At this time, the hydraulic rod 8 is controlled to extend downward through the control panel 20. The extension of the hydraulic rod 8 drives the slide rod 5 to slide downward inside the second groove 6 until it can no longer slide down. The screw component 12 can be fixed up and down, thus completing the fixation of the screw component 12.

[0038] Furthermore, when lubrication of the lead screw component 12 is required, the water pump 202 is first started via the control panel 20. The water pump 202 draws lubricating oil from the oil tank 201, which then enters the outlet rod 204 through the hose 203. The lubricating oil in the outlet rod 204 enters the sponge 209 through the outlet hole 205. When there is enough lubricating oil in the sponge 209, the control panel 20 starts the motor 208. The motor 208 drives the half gear 207 to rotate, which in turn drives the slider 206 to slide downward. The downward sliding of the slider 206 causes the outlet rod 204 and the sponge 209 to slide downward together. The downward sliding stops when the sponge 209 contacts the lead screw component 12, at which point lubrication is achieved. When lubrication is not required, the motor 208 drives the half gear 207 to rotate in the opposite direction, which in turn drives the slider 206 to slide upward. The upward sliding of the slider 206 causes the outlet rod 204 and the sponge 209 to slide upward together away from the lead screw component 12.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
