Description

technical field [0001] The invention relates to the technical field of long U-tube bending equipment, in particular to a four-station long U-tube automatic bending equipment. Background technique [0002] At present, long U-tubes are mostly used in the air-conditioning manufacturing industry and are an important part of the air-conditioning heat exchanger. With the technological development of the air-conditioning and refrigeration industries, the requirements for the heat exchange performance of the heat exchange unit itself are more stringent to compensate for the performance of alternative refrigerants. low. Therefore, the heat exchanger structure (type of heat exchange tubes and fins) and the related heat exchanger forming process are important factors affecting the heat exchange performance, and are of great significance for improving the overall heat exchange performance of the heat exchanger. The existing long U pipe bending machine is to process and bend the pipe fi...

AI Technical Summary

Problems solved by technology

The existing long U pipe bending machine is to process and bend the pipe fittings to meet the requirements, but the current long U pipe bending machine generally adopts the bending method of feeding, bending and receiving materials at one time, and the production efficiency is relatively low; Some use the cutter to directly cut the pipe fittings with a set length during the feeding process. This cutting method is likely to cause irregular cuts of the pipe fittings and affect the quality of the pipe fittings.
