Cold header with lubricating oil circulating filtering device

Abstract

The cold header comprises a cold header body, a lubricating oil tank is arranged at the bottom of the cold header body, a vacuum oil filtering device is arranged on one side of the cold header body, the vacuum oil filtering device comprises a vacuum tank, a heating tank is arranged in the vacuum tank, and the heating tank is arranged in the vacuum tank. A centrifugal oil filtering and heating device is arranged in the heating tank, an oil inlet pipe is connected between the inner bottom of the lubricating oil tank and the centrifugal oil filtering and heating device, and a coarse filter is arranged between the two ends of the oil inlet pipe. By arranging the centrifugal oil filtering and heating device, a centrifugal oil filtering mode is matched in the vacuum filtering process of lubricating oil, the filtering effect of the lubricating oil is improved, the lubricating oil is evenly filtered in a centrifugal filter cylinder under the matching of an oil smearing cylinder, the heating rate during filtering is increased, and therefore the service life of the whole equipment is prolonged; the cyclic utilization efficiency of lubricating oil is improved, and the service life of the cold header is prolonged.

Description

technical field [0001] The invention belongs to the technical field of cold heading machines, in particular to a cold heading machine with a lubricating oil circulating filter device. Background technique [0002] The lubricating oil enters the oil suction pipe through the oil filter and is delivered by the oil pump to the transmission parts of the cold heading machine that need to be lubricated. The used lubricating oil flows back into the oil tank through the oil return pipe, and is recycled again and again. [0003] At present, a patent CN203418050U has been published for a cold heading machine with a lubricating oil circulation filter device, which uses a centrifugal oil filter to filter the lubricating oil and then re-sends it into the oil tank. This method requires centrifugal oil filtering during use. The machine is always in working condition, resulting in short service life and unable to analyze the water in the lubricating oil. After long-term centrifugal filtratio...

Problems solved by technology

[0003] At present, a patent CN203418050U has been published for a cold heading machine with a lubricating oil circulation filter device, which uses a centrifugal oil filter to filter the lubricating oil and then re-sends it into the oil tank. This method requires centrifugal oil filtering during use. The machine is always in working condition, resulting in short service life and unable to analyze the water in the lubricating oil. After long-term centrifugal filtration, it is easy to cause emulsification of the lubricating oil, and in cold weather, the fluidity of the lubricating oil is small, not easy It is beneficial to centrifugal filtration and affects the normal operation of the equipment
