Anti-reversing device for air conditioning heat exchanger core L-shaped bending machine

Abstract

The invention provides an anti-reversing device for an air conditioning heat exchanger core L-shaped bending machine and belongs to the production field of refrigeration equipment. The specific structure of the device is as follows: an electric cylinder mounting base (2) is fixed on the working bedplate (15) of the bending machine and an electric actuator (10) fixed on the electric cylinder mounting base (2) is fixed with an electric cylinder connecting plate (8); the lower end of a connecting plate (7) is fixed with the electric cylinder connecting plate (8), while the upper end of the connecting plate (7) is fixed with an air cylinder mounting plate (6), and the side surface of the connecting plate (7) is fixed with a lower plate (9); an air cylinder (4) is fixed with an upper plate (13) by use of a mounting base (3); the upper plate (13) is connected with the lower plate (9) in a sliding manner and the lower plate (9) is connected with the working bedplate (15) in a sliding manner; during working, the electric actuator (10) drives the lower plate (9) to slide and the air cylinder (4) drives the upper plate (13) to slide. The device is capable of effectively avoiding fin reversing; the quality and the yield of the heat exchange products are improved.

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 ...

AI Technical Summary

Problems solved by technology

Since the fins of the heat exchanger core are very thin, it is very easy to flip the fins under external force bending

The existing bending equipment does not have any measures to protect the fins, so it is difficult to meet the quality requirements of the product, and the product qualification rate is not ideal
