Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a bending device for processing heat exchangers. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. Heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc. Many current heat exchangers need to use bending machines to process straight heat exchange tubes into spiral structures during the manufacturing process. [0003] During the use of the bending machine in the prior art, it is not convenient to disassemble and assemble the heat exchange tube, so that the processing efficiency is low, and in the bending process, only a certain angle can be bent at a time, which requires multiple times Pause makes the processing efficien...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems in the prior art that the bending machine in the prior art is inconvenient to disassemble and assemble the heat exchange tube during use, so that the processing efficiency is low, and in the bending process, a single Only a certain angle can be bent at a time, which requires multiple pauses, which makes the processing efficiency low, and it is not convenient to adjust the processing pitch of the spiral heat exchange tube, so that it is not easy to process spiral heat exchange tubes of different specifications.
