圆管压弯装置
By designing a forming convex circle and slider assembly with a curvature radius greater than the inner bending radius of the pipe bend, the problems of inner concavity and dimensional deviation in the forming of round pipe bends were solved, and a stable and low-damage pipe bend forming process was achieved.

AI Technical Summary
Existing technologies often result in problems such as inner wall concavity, pipe end deformation, and dimensional deviations in the first and last straight arm sections during the forming process of round pipe bending.
A round tube bending device is used. By designing the curvature radii of the first and second forming convex circles to be greater than the inner bending radius of the bent tube, and combining the slider assembly and the tube blank positioning block, the tube blank is stably positioned and gradually bent, avoiding local buckling.
This effectively reduces the risk of internal dents in the bends, ensures the integrity of the pipe ends and the length of the straight arm sections at both ends, and improves production efficiency and product quality.
