Description

Technical Field

[0001] The invention relates to the technical field of bearing ring processing auxiliary equipment, and in particular to a multi-system integrated centralized supply circulation optimization device and method. Background Art

[0002] As the core component of the bearing, the machining accuracy and surface quality of the bearing ring directly affect the overall performance and life of the bearing. In the production process of bearing rings, the ring rolling machine plays a vital role. However, traditional ring rolling machines have many shortcomings in cold rolling oil management, hydraulic system control, and workpiece cleaning, which limits the further improvement of bearing ring production efficiency and quality.

[0003] Insufficient cold rolling oil circulation supply system: In the ring rolling process of bearing rings, due to the lack of effective filtering and recycling mechanism, the waste of cold rolling oil is serious, which increases production costs and does not meet the requirements of resource conservation and environmental protection.

[0004] Stability and reliability of hydraulic system: The hydraulic system is the power source of the ring rolling machine, and its stability and reliability directly affect the operating efficiency and processing quality of the equipment. However, traditional hydraulic systems are prone to problems such as excessive oil temperature and deterioration of oil quality under high temperature and high pressure environments, resulting in increased wear and frequent failures of hydraulic components. In addition, tiny particles in the hydraulic system will also aggravate the wear and blockage of components, affecting the normal operation of the hydraulic system, which not only increases the maintenance cost of the equipment, but also reduces production efficiency and processing quality.

[0005] Insufficient workpiece cleaning: Bearing rings need to be thoroughly cleaned after ring rolling to remove surface oil and metal debris.

[0055] By adopting the above technical solution, the water returning to the water reservoir 101 can be used to remove floating oil by the oil skimmer 107, and then pumped into the first filter 103 for filtration through the first circulation pump 102. The filtered water flows back into the high-pressure cleaning device to clean the workpiece.

[0056] The drain outlet of the oil skimmer 107 is connected to an oil drain pipe 1071, which can discharge the oil skimmed by the oil skimmer into a collection box for centralized collection.

[0057] The water outlet of the first circulation pump 102 is connected with a first bypass pipe 105, and the water outlet of the first bypass pipe 105 is connected with the inside of the water reservoir 101. The first bypass pipe 105 is installed with a first safety valve 1051. When the water pressure in the first filter 103 is too high, the first safety valve 1051 is opened to re-introduce the water pumped out by the first circulation pump 102 into the water reservoir 101 to prevent the first filter 103 from being damaged due to excessive water pressure.

[0058] A second sedimentation hopper 2011 is installed at the lower end of the hydraulic oil pool 201. The sewage outlet of the second sedimentation hopper 2011 is connected to a second sewage pipe 20111. A second sewage valve 20112 is installed on the second sewage pipe 20111.

[0060] An electric heating rod 106 for heating the water inside the water reservoir 101 is fixedly installed inside the water reservoir 101. When the temperature is low, the water in the water reservoir 101 can be heated and then the heated clean water is filtered through the first filter 103 by the first circulation pump 102 and then sent to the high-pressure cleaning device to ensure the normal operation of the cleaning operation.

[0062] A temperature sensor is installed at the hydraulic oil supply port 2042, which can monitor the temperature of the hydraulic oil pumped out of the hydraulic oil supply port 2042 in real time. When the temperature of the hydraulic oil pumped out of the hydraulic oil supply port 2042 is lower than the set temperature, the controller will control the temperature control valve 20411 to reduce the opening. When the temperature of the hydraulic oil pumped out of the hydraulic oil supply port 2042 is higher than the set temperature, the controller will control the temperature control valve 20411 to increase the opening, so as to ensure that the temperature of the hydraulic oil pumped out of the hydraulic oil supply port 2042 remains within the set threshold.
