[0018] Preferably, the support frame is in a Y-shape, and the two support frames are symmetrically arranged.

[0019] Preferably, the method for using the copper-aluminum composite plate and strip pressing device comprises the following steps:

[0020] S1: Two copper strips are conveyed by two conveying racks. When the copper strips are conveyed between the auxiliary pressure roller and the hollow tube, the rotating shaft is driven to rotate by the driving motor. When the arc-surface pressing plate on the rotating shaft is squeezed by the angle cut at the end of the arc-shaped card plate, the arc-surface pressing plate pulls the pressing plug to move in the negative pressure adsorption sleeve, and cooperates with the sealing adsorption ring to adsorb the bottom of the copper strip, so that one end of the copper strip moves with the negative pressure adsorption sleeve, so that one end of the copper strip moves downward between the two sealing plates;

[0021] When the arc-shaped clamping plate is separated from the inner arc surface of the arc-surface pressure plate, the arc-surface pressure plate is reset under the action of the reset force of the spring telescopic plate, and drives the pressure plug to reset in the negative pressure adsorption sleeve, so that the sealing adsorption ring at the end of the negative pressure adsorption sleeve is separated from the copper belt, and the negative pressure adsorption sleeves on the multiple groups of arc-surface pressure plates are operated alternately, so that the copper belt is bent and transported downward;

[0022] S2: Then the aluminum liquid is transported to between the two copper belts through the conveying pipe, and when the hollow tube rotates, the driving gear drives the driven gear and the driving turntable thereon to rotate, so that the connecting rod pulls the upper rectangular sliding frame to move up and down on the two sealing plates, and when the upper rectangular sliding frame moves up and down, the upper transmission tooth plate drives the rotating gear to rotate, so that the lower rectangular sliding frame moves up and down under the action of the lower transmission tooth plate;

[0023] When the two rectangular sliding frames slide on the two sealing plates, the copper strips are rolled and pressed by the pressing rollers at the ends of the deflection pressing plates to ensure the effect of the two copper strips and the aluminum liquid being pressed together;

[0024] When the two rectangular sliding frames move toward each other, the second hinged cooling tube and the first hinged cooling tube are driven to fold, and the surface of the copper strip is cooled by cooling water inside the first hinged cooling tube and the second hinged cooling tube;

[0025] S3: During the deflection of the first hinged cooling pipe, the push plate is pushed to deflect, thereby driving the sliding block to slide in the water absorption jacket, and the cooling water in the upper first hinged cooling pipe and the upper second hinged cooling pipe is sucked into the interior of the water absorption jacket through the one-way delivery pipe, and the cooling water in the cold water tank is replenished into the upper first hinged cooling pipe and the upper second hinged cooling pipe;

[0026] Then, when the two rectangular sliding frames move back to back, the second articulated cooling tube and the first articulated cooling tube are driven to expand, so as to cool down the surface of the copper strip, and when the first articulated cooling tube on the lower side is deflected, the cooling water in the water absorption jacket is transported to the first articulated cooling tube on the lower side and the second articulated cooling tube on the lower side, so as to replace the coolant in the first articulated cooling tube on the lower side and the second articulated cooling tube on the lower side, and the coolant in the first articulated cooling tube on the lower side and the second articulated cooling tube on the lower side is transported to the water storage tank through the connecting water delivery rack, so as to complete the circulation of cooling water.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] In the present invention, the rotating shaft is driven to rotate by a driving motor. When the arc-surface pressure plate on the rotating shaft is squeezed by the angle cut of the end portion of the arc-shaped clamping plate, the arc-surface pressure plate pulls the pressing plug to move in the negative pressure adsorption sleeve, and cooperates with the sealing adsorption ring to adsorb the bottom of the copper belt, so that one end of the copper belt moves with the negative pressure adsorption sleeve, and one end of the copper belt moves downward between the two sealing plates, thereby ensuring stable downward transportation of the copper belt and facilitating the conveying pipe to convey the aluminum liquid between the two copper belts, so as to facilitate the subsequent pressing of the copper and aluminum plates by the device.

[0029] In the present invention, the aluminum liquid is transported between the two copper belts through a conveying pipe, and when the hollow tube rotates, the driving gear cooperates with the driven gear and the driving turntable thereon to rotate, so that the connecting rod pulls the upper rectangular sliding frame to perform up and down reciprocating motion on the two sealing plates, and when the upper rectangular sliding frame moves up and down, the upper transmission tooth plate cooperates with the rotating gear to rotate, so that the lower rectangular sliding frame performs up and down reciprocating motion under the action of the lower transmission tooth plate; and when the two rectangular sliding frames slide on the two sealing plates, the copper belts are rolled and pressed by the pressing roller at the end of the deflection pressure plate, thereby ensuring the effect of pressing the two copper belts with the aluminum liquid.

[0030] In the present invention, when the two rectangular sliding frames move toward each other, the second hinged cooling tube and the first hinged cooling tube are driven to fold, and the surface of the copper strip is evenly cooled by the cooling water inside the first hinged cooling tube and the second hinged cooling tube.

[0031] In the present invention, the push plate is pushed to deflect during the deflection of the first articulated cooling tube, thereby driving the sliding block to slide in the water absorption jacket, and the cooling water in the upper first articulated cooling tube and the upper second articulated cooling tube is sucked into the interior of the water absorption jacket through the one-way delivery pipe. Then, when the two rectangular sliding frames move away from each other, the second articulated cooling tube and the first articulated cooling tube are driven to unfold, so as to cool down the surface of the copper strip. When the lower first articulated cooling tube is deflected, the cooling water in the water absorption jacket is delivered to the lower first articulated cooling tube and the lower second articulated cooling tube, so as to replace the coolant in the lower first articulated cooling tube and the lower second articulated cooling tube, and the coolant in the lower first articulated cooling tube and the lower second articulated cooling tube is delivered to the water storage tank through the connecting water delivery rack, so as to complete the circulation of cooling water and ensure the uniformity of the device in cooling the copper and aluminum plates.

[0059] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown:

[0060] S1: The two copper strips are conveyed by two conveying racks 6. When the copper strips are conveyed between the auxiliary pressure roller 81 and the hollow tube 82, the rotating shaft 84 is driven to rotate by the driving motor 85. When the arc-surface pressing plate 87 on the rotating shaft 84 is squeezed by the angle cut of the end of the arc-shaped clamping plate 811, the arc-surface pressing plate 87 pulls the pressing plug 88 to move in the negative pressure adsorption sleeve 89, and cooperates with the sealing adsorption ring 810 to adsorb the bottom of the copper strip, so that one end of the copper strip moves with the negative pressure adsorption sleeve 89, so that one end of the copper strip moves downward between the two sealing plates 96;

[0061] When the arc-shaped clamping plate 811 is separated from the inner arc surface of the arc-surface pressing plate 87, the arc-surface pressing plate 87 is reset under the action of the reset force of the spring expansion plate 86, and drives the pressing plug 88 to reset in the negative pressure adsorption sleeve 89, so that the sealing adsorption ring 810 at the end of the negative pressure adsorption sleeve 89 is separated from the copper belt, and the negative pressure adsorption sleeves 89 on the multiple groups of arc-surface pressing plates 87 are operated alternately, so that the copper belt is bent and transported downward;

[0062] S2: Then the aluminum liquid is transported to between the two copper belts through the conveying pipe 7, and when the hollow tube 82 rotates, the driving gear 812 drives the driven gear 92 and the driving turntable 91 thereon to rotate, so that the connecting rod 94 pulls the upper rectangular sliding frame 99 to move up and down on the two sealing plates 96, and when the upper rectangular sliding frame 99 moves up and down, the upper transmission tooth plate 98 drives the rotating gear 97 to rotate, so that the lower rectangular sliding frame 99 moves up and down under the action of the lower transmission tooth plate 98;

[0063] When the two rectangular sliding frames 99 slide on the two sealing plates 96, the copper strips are rolled and pressed by the pressing rollers 914 at the ends of the deflection pressing plates 912, thereby ensuring the effect of the two copper strips and the aluminum liquid being pressed together;

[0064] When the two rectangular sliding frames 99 move toward each other, the second hinged cooling tube 109 and the first hinged cooling tube 106 are driven to fold, and the surface of the copper strip is cooled by the cooling water inside the first hinged cooling tube 106 and the second hinged cooling tube 109;
