Description

Technical Field

[0001] The utility model relates to a metal oil pipe bending tool for a hydraulic station. Background Art

[0002] The hydraulic station is an independent hydraulic device. It supplies oil according to the requirements of the drive device (host) and controls the direction, pressure and flow of the oil flow. It is suitable for various hydraulic machines where the host and the hydraulic device can be separated. The motor drives the oil pump to rotate, and the pump sucks oil from the oil tank and pumps oil to convert mechanical energy into the pressure energy of hydraulic oil. The oil pipe of the hydraulic station is used to connect the hydraulic pump, hydraulic valve and other hydraulic components to form a complete hydraulic system. The oil pipe is usually made of metal material and has certain pressure resistance and corrosion resistance. In order to match the structure, size and layout of the oil tank of the hydraulic station, some metal oil pipes need to be formed into a continuously wound coil structure. However, the existing bending equipment cannot bend the coil structure on the metal oil pipe in one go according to the designed established shape, but must divide the bending process into multiple steps and perform them in sequence. After completing the previous bending step, it is necessary to pause and manually adjust the position of the metal oil pipe to ensure the position and dimensional accuracy of the next bending step. Therefore, the operation steps are relatively cumbersome, and multiple pauses waste a lot of time, which leads to low processing efficiency and needs further improvement. Utility Model Content
