Description
Technical Field
[0001] The utility model relates to the technical field of pipe bending machines, in particular to a vacuum pipe bending machine. Background Art
[0002] The primary purpose of vacuum piping bending is to adapt to specific piping layouts and space constraints. In some industrial and scientific fields, vacuum piping systems require curved bending based on specific site layouts and design requirements to ensure smooth piping placement. Furthermore, bent piping can better adapt to varying spatial requirements, enabling piping systems to operate more effectively in complex engineering environments. Furthermore, bent piping reduces the need for connectors and joints, reducing the risk of leakage and improving system sealing and reliability.
[0003] However, existing vacuum pipe bending equipment usually needs to clamp and fix the vacuum pipe when bending the vacuum pipe. However, the outer wall of the softer vacuum pipe is softer, and different types of clamps will cause some deformation to the outer wall of the pipe during long-term clamping, thereby affecting the appearance of the vacuum pipe. Therefore, those skilled in the art provide a vacuum pipe bender to solve the above problems. Utility Model Content
