Problems solved by technology
With the continuous development of manufacturing technology, the product competition in the manufacturing industry is becoming more and more fierce. It is necessary to improve the market competitiveness of hydraulic presses. The existing hydraulic presses will cause the temperature of the hydraulic oil to rise when it is working. When the temperature of the hydraulic oil rises to a certain level, it will It affects the working performance of the hydraulic machine, so it is necessary to dissipate heat from the hydraulic oil. In order to improve this situation, the methods currently used include air cooling and water cooling, but the cooling effect of these two methods is not ideal, and the heat exchange is insufficient. Low

The invention provides a hydraulic machine hydraulic oil cooling device. The hydraulic machine hydraulic oil cooling device is good in cooling effect and high in cooling efficiency. According to the hydraulic machine hydraulic oil cooling device, hydraulic oil is distributed through a main distribution pipe and is initially cooled in first radiating pipes; through combination of water cooling andair cooling, cooling water is introduced into cooling strips, fans are used for accelerating air flow between the first radiating pipes so as to accelerate heat loss of the hydraulic oil in the firstradiating pipes; a plurality of arc-shaped grooves formed in each cooling fin form multiple air channels, so that the air passes through the arc-shaped grooves to improve the cooling efficiency; cooling devices are used for secondary cooling of hydraulic oil, and the cooling time of the hydraulic oil in inner pipes is prolonged through internal and external thread structures of second radiating pipes; through the cooling fins, the heat exchange area is increased, and cooling water in outer pipes form turbulent flow to improve the cooling efficiency; and the second radiating pipes are arrangedin a box to form tertiary cooling, and the cooling reliability is greatly improved.
Description
technical field [0001] The invention relates to the technical field of hydraulic mechanical equipment, in particular to a hydraulic oil cooling device for a hydraulic machine. Background technique [0002] A hydraulic press is a machine that uses hydrostatic pressure to process various materials. It is often used in pressing processes and pressing forming processes, such as forging, stamping, cold extrusion, straightening, bending, flanging, sheet drawing, powder metallurgy, pressing Pretend to wait. From the invention of the first hydraulic press in 1795 to the present, the hydraulic press has experienced more than 200 years of improvement and innovation. Because of its "universal" processing technology, the hydraulic press is widely used in various industries of national production. With the continuous development of manufacturing technology, the product competition in the manufacturing industry is becoming more and more fierce. It is necessary to improve the market compe...
