Lubricating oil filtering device inside copper pipe blanking and molding equipment

Abstract

The invention relates to the technical field of refrigeration equipment and in particular discloses a lubricating oil filtering device inside copper pipe blanking and molding equipment. The filtering device comprises an oil delivery pipeline connected with an oil tank, wherein a built-in loss prevention filtering member is arranged in the oil delivery pipeline; a gas mixing pipeline is arranged in the oil tank; a gas mixing solenoid valve and an oil delivery solenoid valve are respectively arranged on the gas mixing pipeline and the oil delivery pipeline; the gas mixing solenoid valve is used for controlling compressed gas to enter the oil tank, and the compressed gas is mixed with the oil in the oil tank so as to form a gas-oil mixture; and the oil delivery solenoid valve and the gas mixing solenoid valve are matched to adjust the delivery frequency of the gas-oil mixture. According to the built-in loss prevention filtering net structure consisting of a rigid filtering net and a flexible filtering net, impurities are separated from lubricating oil containing impurities at the filtering net, and the difficulties that small-size oil nozzles of bent processing and forming dies are blocked to cause copper pipe bending crack and a series of quality problems are solved. Meanwhile, the device is provided with an airflow recoil cleaning member, so that the filtering net is cleaned by timely and automatic blowback gas and is contained in a container.

Description

technical field [0001] The invention relates to the technical field of refrigerating equipment, in particular to a lubricating oil filtering device for cutting heat exchange copper tubes commonly used in refrigerating equipment and for forming equipment. Background technique [0002] The existing refrigeration system contains many pipeline products, which must be cut, bent and other mechanical processing, and lubrication is necessary during the processing. At the same time, the industry generally adopts the scheme of lubricating oil recycling, so the processing chips, dust and other impurities contained in it are problematic. , is a major problem in the industry. [0003] The current operation method of lubricating oil recycling: the operator simply puts the once-used lubricating oil to rest, and then directly adds it to the oil storage tank of various refrigeration system parts cutting and processing molding equipment, and then through the oil storage tank Processing oil i...

Problems solved by technology

[0015] The object of the present invention is to propose a lubricating oil filter device for copper tube blanking and forming equipment, which can be used to solve the current refrigeration system components, such as air conditioners, refrigerators, etc. (such as U-shaped elbows of metal products, hereinafter referred to as "elbows") ”) The oil used in the blanking and processing molding equipment has on-site pollution, pollution after one use, and impurities such as copper scraps and fluff in the oil are directly added to the oil storage tank of the equipment, resulting in failure of the oil supply system of the equipment. Blockage of oil passages and nozzles, resulting in failure of oil supply, poor lubrication of copper pipes during elbow bending, pipe wall cracking, dark cracks, local thinning and other quality defects
