Copper casing pipe coiler

Abstract

The invention relates to the field of a bending forming processing technology of casing pipe materials, in particular to the field of a preparing technology of a multi-layer spiral-structure copper casing pipe for a heat exchanger. The invention particularly discloses a copper casing pipe coiler. The copper casing pipe coiler comprises a rack, and a bending mechanism and a pipe coiling disc which are arranged on the rack, wherein the pipe coiling disc is driven by a speed reducer with a motor to rotate through a rotating shaft, the rotating shaft penetrates through a bearing and is supported by bearing pedestals arranged on the rack, and the speed reducer is fixed to a sliding table of the rack and can move on the surface of the rack in the axial direction of the rotating shaft through the sliding table; the bending mechanism comprises a dynamic pipe conveying wheel group arranged below the pipe coiling disc, a bending wheel arranged among the dynamic pipe conveying wheel group and a guide wheel which is positioned between the dynamic pipe conveying wheel group and the pipe coiling disc and is close to the periphery of the pipe coiling disc; and a pipe head positioning clamp is arranged on the pipe coiling disc. The copper casing pipe coiler can process the copper casing pipe and make a multi-layer spiral coiled pipe for the heat exchanger and has the advantages of being high in processing efficiency, neat and even in coiled pipe appearance and low in worker labor intensity.

Description

Technical field [0001] The invention relates to the technical field of bending and forming processing of sleeve pipes, in particular to the technical field of preparation of copper sleeves with a multilayer spiral structure for heat exchangers. Background technique [0002] The coil is used as a heat exchanger in the carbon dioxide heat pump system. The copper sleeve is bent and wound into a multi-layer spiral structure. In order to improve the heat exchange efficiency and save the space of the heat pump unit, the inner and outer sleeves of each spiral need to be tight. At the same time, because the copper sleeve is composed of an inner tube and an outer tube, the mass of the coil per unit volume is very large. The metal coil machine must adopt the coil tube to receive and carry the tube body deformed by the bending deformation mechanism. After the coil is completed , Remove the coil from the coil tray. [0003] The prior art metal coil machine cannot be directly used for the bend...

AI Technical Summary

Problems solved by technology

[0003] The metal coil machine in the prior art cannot be directly used to bend the casing, and there are the following problems: when bending, the inner tube of the casing is not in contact with the bending deformation mechanism, resulting in uneven stress on the inner and outer tubes of the casing , resulting in relative sliding, resulting in uneven and non-uniform deformation of the inner tube and the outer tube; the existing metal coil mac
