Description

technical field

[0001] The invention belongs to the technical field of mechanical equipment for refrigeration equipment production, and in particular relates to an anti-reversal device for an L-shaped bending machine for an air-conditioning heat exchanger core. Background technique

[0002] The heat exchanger is the core device in the refrigeration equipment, and its structure includes copper tubes, fins and end plates. The fins and the end plates are provided with round holes, and the copper tubes pass through the round holes. After being expanded by the tube expansion equipment, the copper tubes, fins and end plates are integrated to form a heat exchanger core. According to the actual needs of the heat exchanger, the copper tubes and fins used to make the heat exchanger are usually bent into a certain shape. The bending process of the heat exchanger core is as follows: clamp one end of the heat exchanger core, rotate the bending roller for bending, and slide the free end ...
