Abstract

The invention discloses a finned pipe bending machine. The machine comprises a machine seat, a feeding device and a bending device; the feeding device can fix, push or rotate pipes; and the bending device is provided with a variable-R mechanism, a deflection mechanism and a rotating piece. According to the machine, the variable-R mechanism is arranged, so that the distance between a screw rod andthe axis of a base is adjusted, any bending radius can be adjusted, and different pipe bending radius requirements can be met; the deflection mechanism is arranged, the self-adaptive force of the pipes cooperates with the inside structure of the deflection mechanism during pipe bending, and deflection in the opposite direction of the rotating direction of the rotating piece is performed, so that pipe surface dents produce during pipe bending are reduced, subsequent bent pipe and fin connection positions are not prone to loosening, and the stability of the performance of a heat exchanger is kept.

Description

technical field [0001] The invention belongs to the technical field of pipe bending, and in particular relates to a finned pipe bending machine. Background technique [0002] In order to improve the heat exchange efficiency of the heat exchanger, it is usually necessary to bend the heat exchange tube into multiple bends, and cover the surface of the heat exchange tube with multiple fins. This requires that when processing finned tubes, the tubes should be bent first. [0003] Existing pipe bending equipment realizes bending by clamping the two ends of the pipe and making one end rotate together with the clamp. During the whole process, the force exerted by the side of the clamp on the pipe is always greater than the force exerted by the inside of the clamp on the pipe, so that the surface of the bent pipe is easy to form dents where it contacts the side of the clamp. When the fins are connected, the larger the connection gap, the connection between the elbow and the fins i...
