Description

Technical Field

[0001] The utility model relates to the technical field of cooling and lubricating devices, in particular to a cooling and lubricating device for a finishing mill used in the production of spring steel. Background Art

[0002] During the production process of the finishing mill, the temperature of the rolls will rise due to the heat of rolling deformation, the heat generated by the metal friction between the workpiece rolls and the workpiece, the heat generated by the friction between the working rolls and the support rolls, and the heat of the workpiece itself. The rolling accuracy of the workpiece will be greatly affected due to the thermal expansion and contraction characteristics of the metal, resulting in an unstable rolling process, poor plate shape after rolling, and even affecting normal rolling production. Therefore, lubricants must be used for lubrication and cooling during the rolling process. However, after the current cooling and lubrication device lubricates the working rolls and support rolls, the dripping lubricating cooling oil is mixed with some processing debris on the workpiece, which drips directly into the oil storage tank, causing the lubricating cooling oil to be mixed with the processing debris and directly participate in the cooling and lubrication cycle, resulting in blockage of the oil outlet channel of the working roll or support roll, resulting in poor cooling and lubrication effect, low efficiency, and more troublesome cleaning.

When the finishing mill needs to be cooled and lubricated, the output shaft of the motor of the linear slide is started to rotate, and the screw rod is driven to rotate by the rotation of the output shaft of the motor of the linear slide. Due to the threaded connection between the slider of the linear slide and the screw rod and the guide and limit of the slider of the linear slide by the slide rail of the linear slide The rotation of the screw rod drives the slider of the linear slide to slide along the slide rail of the linear slide with the oil storage tank 300 until the oil storage tank 300 is brought to the bottom of the finishing roller 102 of the finishing mill, and then the finishing mill is started to work, and the circulating pump of the cooling and lubricating device is started to work, and the cooling and lubricating liquid is drawn into the finishing roller 102 on the finishing mechanism 100 for cooling and lubrication. The lubricated cooling and lubricating liquid will drip into the oil collecting tank through the oil outlet on the finishing roller 102, and the impurities will be filtered out by the filtering effect of the filter plate 401. The filter assembly 400 is blocked on the filter plate 401, and the filtered cooling lubricating oil re-enters the engine oil tank.
