Die, device and method for forming heat exchange coil pipe

Abstract

The invention discloses a die, a device and a method for forming a heat exchange coil pipe. The die comprises a die holder and a formed spiral coil pipe which is arranged on the die holder and is fixed with the die holder, wherein the middle part of the die holder is bulged upwards, and the height of the die holder at a position farther away from a central position is lower; and the formed spiral coil pipe is in a spiral shape, the center of the formed spiral coil pipe is positioned on the middle part of the die holder, and the formed spiral coil pipe forms a formed surface of the heat exchange coil pipe. The die comprises the die holder and the formed spiral coil pipe which is arranged on the die holder and is fixed with the die holder; the die holder is in a circular shape, the middle part of the die holder is bulged upwards, and the height of the die holder at a position farther away from the central position is lower;; and the formed spiral coil pipe is in a spiral shape, is adaptive with the outline of the die holder and forms the formed surface of the heat exchange coil pipe. According to the die, the manufacturing cost of the heat exchange coil pipe is lower, and the machining efficiency is higher.

Description

technical field [0001] The invention belongs to the field of heat exchange coil processing, and in particular relates to a heat exchange coil forming die, a forming device and a forming method. Background technique [0002] The heat exchange coil is generally a copper tube, which is mainly used for heat exchange. In the processing of the existing heat exchange coil, a special heat exchange coil forming die is required. The existing heat exchange coil forming die is manufactured The high cost further increases the manufacturing cost of the heat exchange coil. [0003] On the other hand, in the process of processing heat exchange coils, it is mainly done by hand, and in the process of processing, two people usually cooperate with each other to operate. The existing manual processing method results in high labor intensity for workers and makes the There are large errors in the processed heat exchange coils, it is difficult to ensure the consistency of dimensions, and the proce...
