Description

technical field [0001] The invention relates to the field of mechanical engineering, in particular to a numerically controlled pipe bending simulation method and device. Background technique [0002] Elbows are widely used in complex products such as missiles, launch vehicles, satellites and aircraft, and they transport fuel, hydraulic oil, gas and other working media. The bent pipe is subject to deformation and high-frequency vibration in working condition, as well as the impact and pulsation of the fluid in the pipe, and part of it is also affected by high pressure and temperature changes. Therefore, the bending pipe production process in complex products has strict requirements, and CNC pipe bending machines are usually used for processing. NC (Numerical Control, digital control, NC for short) program effectiveness. [0003] In the existing technology, the research on the simulation of CNC pipe bending process generally relies on specific projects, most of which are aim...
