According to another aspect of the present invention, a method for bending a double-layer heat exchanger is provided, where the method uses the clamping mechanism in the above embodiment to bend the double-layer heat exchanger. The method comprises the following steps: step S10: the bending feeding mechanism is used for placing the anti-falling supporting plate 12 of the clamping mechanism in the clamping space, locking the anti-falling supporting plate 12 by the layered pushing cylinder 7, and placing the double-layer heat exchanger to be bent at a preset position on the workbench through the robot clamp; step S20: the lower pressure cylinder 1 is controlled to act so that the lower surface of the anti-falling sheet supporting plate 12 is abutted with the upper surface of the bottom layer heat exchanger of the double-layer heat exchanger; step S30: the clamping cylinder 5 is controlled to act to drive the layering cylinder 8 to move downwards so that the layering plate 10 is positioned below the copper pipe of the top-layer heat exchanger, the clamping cylinder 5 is controlled to act in the vertical direction to lift the top layer of the double-layer heat exchanger by a preset height, and the bending feeding mechanism is controlled to drive the clamping mechanism to act so that the anti-falling sheet supporting plate 12 is inserted between the bottom-layer heat exchanger and the top-layer heat exchanger of the double-layer heat exchanger; step S40: the layering air cylinder 8 is controlled to act so as to enable the layering plate 10 to be far away from the double-layer heat exchanger, the clamping air cylinder 5 is controlled to act so as to drive the layering air cylinder 8 and the layering plate 10 to move upwards to a preset position, and the bending mechanism is used for bending the double-layer heat exchanger.
Specifically, by adopting the clamping mechanism to process the heat exchanger, especially the double-layer condenser, the problems of cross rewinding of fins and pull damage of copper pipes of the double-layer condenser can be eliminated, an automatic working mode of the robot is realized, and the labor cost is saved.
Wherein, the condenser presss from both sides to get through the robot when coming on the conveying line and bends on the bender of bending mechanism, because double-deck condenser fin cross deformation when bending arouses the back-up, increase and prevent that the back-up layer board is U drags the device and can eliminate this problem, if increase people's station and operate just can't utilize the robot to realize the automation, and automatic put and get double-deck condenser U drags the device and can move through program control and reach the purpose that automatic put and get U drags, both practiced thrift the human cost like this, also can realize automatic mode of operation.
The automatic double-layer condenser U-shaped dragging device is added to automatically bend the double-layer condenser, the phenomenon that the fins of the condenser are rewound and the copper tubes at the end parts of the condenser are stretched and deformed during bending is eliminated, and the purpose of automatic bending of the condenser is achieved.
The double-layer condenser 13 is conveyed to a designated position through a belt conveying line, then a U-shaped bending machine is required to bend, and two working modes exist: 1. manually carrying the condenser onto a bending machine, and then manually bending the condenser by operating the bending machine; 2. the condenser is clamped onto the bending machine from the conveying line through the robot, and the control system then gives a starting signal to the U-shaped bending machine to achieve automatic bending. Because the fins are easy to rewind and the copper tubes at the end parts are stretched and deformed when the double-layer condenser is bent, the friction between the upper layer and the lower layer of the condenser is reduced by increasing U-shaped drawing, and further the fin rewinding and the copper tube stretching and deformation at the end parts are eliminated. The manual operation bender is according to 1000 per unit/people's output requirement (task output 2000 stations each day, 2 bending machines totally need to join in marriage 2 people), and every operating personnel need carry 1000 double-deck condensers 13 each day, need manual drawing U to drag 2000 times to the manual handling of condenser that bends is on the assembly line frock board chassis, makes the staff bear very heavy intensity of labour. By adding the U-shaped dragging device for automatically picking up the double-layer condenser 13, the automatic production modes of bending the condenser, assembling the bent condenser with the assembly line tooling plate and the like can be realized, the labor intensity of staff is reduced, the staff can be reduced by 2-3 persons, and the labor cost is saved.

The working principle of the clamping mechanism is as follows: the whole structure is fixed on a feeding mechanism of the bending machine, the installation height is required to be adjusted according to the condenser during installation, and the zero position of the feeding mechanism is adjusted through a program. After the program is started, the feeding mechanism of the bending machine advances to a model zero point (non-mechanical zero point), and the anti-falling supporting plate 12 is firstly placed between the layered propulsion cylinder 7 and the limiting plate 11, and the layered propulsion cylinder 7 acts to clamp the anti-falling supporting plate 12. The double-layer condenser 13 is placed on the U-shaped bending machine to be positioned well, the pressing cylinder 1 starts to act, so that the anti-falling sheet supporting plate 12 is pressed to the upper surface of the lower layer of the condenser, and the front end of the anti-falling sheet supporting plate 12 is 2-4mm away from the top of the copper pipe. The clamping cylinder 5 moves downwards to enable the layering cylinder 8 to move downwards, and then the layering cylinder 8 moves to enable the layering plate 10 to move forwards, and the distance between the layering cylinder and the top of the condenser copper pipe is 8-10mm. Then the controller controls the feeding mechanism of the bending machine to advance for 20-25mm, the copper pipe is slightly lifted up by the layering plate 10 in the advancing process, the upper layer and the lower layer of the double-layer condenser 13 generate a gap, then the anti-falling sheet supporting plate 12 is inserted between the upper layer and the lower layer of the condenser along the gap, then the layering cylinder 8 is actuated to retract, the layering plate 10 is retracted to open the copper pipe at the upper layer of the double-layer condenser 13, then the clamping cylinder 5 is actuated to drive the layering cylinder 8 and the layering plate 10 to move upwards to avoid the condenser, then the bending machine starts to actuate to bend, after bending is completed, the feeding mechanism is controlled to drive the device for automatically placing the anti-falling sheet supporting plate 12 of the double-layer condenser 13 to move to the upper side of the anti-falling sheet supporting plate 12, the lower pressing cylinder 1 is actuated to enable the connecting part to be pressed down, then the layering pushing cylinder 7 is actuated to clamp the anti-falling sheet supporting plate 12, then the bending machine is controlled to retract for a distance to pull the anti-falling sheet supporting plate 12 out of the condenser, then the lower pressing cylinder 1 is actuated to move upwards, finally the U-shaped bending machine drives the U-shaped dragging device for automatically placing the double-layer condenser 13 to move back to the zero point, the action of the lower robot is actuated to clamp the condenser to clamp the folded condenser to move to the upper layer condenser to be placed on the upper layer condenser to a machine, and the model of a heat exchanger is waiting for a heat exchange line, and a work is finished.
