Problems solved by technology

[0009] The existing processing method of long U-shaped copper tubes has the following disadvantages: the production efficiency of the equipment is not high, only X (such as 6) long U-tubes can be produced in one working cycle, and the equipment occupies a large amount of workshop area. In large-scale production, in order to improve efficiency, it is necessary to increase the number of bent pipes and require more equipment. The consistency and stability of the products produced in this way cannot be guaranteed due to the difference in equipment, which affects the quality of the products.

Description

technical field [0001] The invention relates to an improved long U-shaped metal pipe processing equipment and its processing method, which is suitable for the processing of long U-shaped copper pipes used in the production process of air conditioners, freezers, refrigerators and other products, and is also suitable for When processing other thin steel pipes or other metal pipes that need to be bent into a U shape. Background technique [0002] In the production process of air conditioners, freezers, refrigerators and other products, long U-shaped copper tubes are used as the main components of the internal pipes of heat exchangers. The pipe is cut into 0.4-5 meters long, and then bent and processed. Due to the requirements of production scale, the current production capacity of domestic electrical appliances manufacturers urgently needs to be continuously improved in order to reduce production costs. Simply relying on expanding the production site and increasing the number...
