Description

Technical Field

[0001] The utility model relates to the technical field of dipped support rollers, in particular to a lubricating device for a lower support roller of a rolling mill. Background Art

[0002] The lower support roller of the hot strip finishing mill is mainly used to receive and convey the strip. Applying lubricating liquid to the surface of the lower support roller can increase the service life of the entire lower support roller and improve the lubrication effect of the transmission between the lower support roller and the hot rolled strip. At present, the work of applying lubricating oil to the lower support roller generally adopts a nozzle to directly spray it to the surface of the lower support roller, or uses an oil absorption strip to apply it to the surface of the lower support roller. However, in this operation, the lubricating oil on the surface of the lower support roller will drip on the lower support roller, and the dripping lubricating liquid directly dripping onto the equipment will not only easily cause a waste of lubricating liquid, but also pollute the equipment. When recycling it using a recovery tank, the lubricating liquid will be mixed with some impurities and needs to be filtered before it can be reused. All of these bring great inconvenience to the lubrication work of the lower support roller. Utility Model Content

[0018] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figure 1-4As shown, the present embodiment describes a lubricating device for the lower support roller of a rolling mill, comprising a support roller 1 and a receiving groove 2 arranged below the support roller 1, the upper part of the support roller 1 extends out from the receiving groove 2, a plurality of nozzles 3 are evenly distributed in the receiving groove 2 at positions corresponding to one side of the support roller 1, the nozzles 3 are provided with oil pipes 4 extending out of the receiving groove 2, the oil pipes 4 are externally connected to an oil pump and an oil tank, a cleaning assembly 5 is provided at the top of the receiving groove 2 at a position corresponding to the other side of the support roller 1, a liquid outlet pipe 6 is provided at the bottom of the receiving groove 2, and a detachable filter head 7 is provided in the liquid outlet pipe 6.

[0021] A retaining plate 8 is horizontally placed on the side wall of the receiving groove 2 , and the nozzles 3 are arranged side by side on the retaining plate 8 , with the nozzles of the nozzles 3 facing one side of the supporting roller 1 .

[0022] The oil pump pumps the lubricating liquid out of the oil tank and transports it to the spray head 3 through the oil pipe 4 , and finally sprays the lubricating liquid onto the surface of the support roller 1 through the nozzle on the spray head 3 .

[0023] The cleaning assembly 5 includes a mounting frame 5a arranged on the top of the receiving groove 2, and a scraper 5b extending toward one side of the support roller 1 is arranged on the mounting frame 5a. The end of the scraper 5b contacts the surface of the support roller 1, and the two are arranged in a close fit. When the support roller 1 rotates, the end of the scraper 5b will scrape the surface of the support roller 1.

[0024] Preferably, the scraper 5b is made of rubber.

[0025] A mounting transverse plate 9 is disposed on the top of the receiving groove 2 , and the mounting frame 5 a is fixedly disposed above the mounting transverse plate 9 .

[0026] The scraper 5 b is provided with a scraping edge at one end that contacts the backup roller 1 .

[0027] The filter head 7 comprises a filter cartridge 7a, and a filter screen 7b is arranged at the opening at the bottom of the filter cartridge 7a. The filter screen 7b can filter the recovered lubricating fluid, thereby filtering out impurities in the lubricating fluid.

[0028] The filter cartridge 7 a is provided with an external thread on the outer side of the upper end thereof, and the interior of the liquid outlet pipe 6 is provided with an internal thread, and the filter cartridge 7 a is threadedly connected in the liquid outlet pipe 6 .

[0029] An annular rim 7c is arranged in the middle of the filter cartridge 7a, an external thread is arranged on the upper part of the filter cartridge 7a, and the annular rim 7c abuts against the edge of the liquid outlet pipe 6.

[0030] The bottom of the receiving tank 2 is a constricted structure, and the liquid outlet pipe 6 is arranged at the lowest end of the constricted structure.

[0031] The working principle of the utility model is as follows: when the support roller 1 is coated with lubricating oil, the oil pump first pumps out the lubricating liquid in the oil tank, and finally sprays it onto the surface of the rotating support roller 1 through the nozzle 3. During the rotation of the support roller 1, the end of the scraper 5b will scrape the surface of the support roller 1. The scraper 5b can not only evenly apply the lubricating liquid to the surface of the support roller 1, but also scrape off the metal debris, particles and other impurities adhered to the surface of the support roller 1, thereby ensuring the smoothness of the surface of the support roller 1, and the excess lubricating liquid sprayed onto the surface of the support roller 1 is removed. The lubricating fluid will drip on the supporting roller 1, and the dripping lubricating fluid and impurities will be collected by the receiving tank 2. At the same time, the lubricating fluid will flow down along the liquid outlet pipe 6. In the process of flowing down, the lubricating fluid will be filtered by the filter head 7 installed thereon, and the impurities will be blocked by the filter screen 7b, while the lubricating fluid will flow down and fall into the oil tank. The lubricating fluid recovered in the oil tank can be reused. After working for a period of time, the filter head 7 can be removed, and the impurities filtered out in the filter head 7 can be cleaned, and finally the filter head 7 can be reinstalled.

[0032] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms.
