The invention also provides a forming method of the copper-aluminum composite strip forming device, which specifically comprises the following steps:
S1, passing the copper strip 11 between the first guide roller 82 and the second guide roller 83, passing the aluminum strip 12 between the third guide roller 84 and the fourth guide roller 85, and then passing the rear ends of the copper strip 11 and the aluminum strip 12 between the upper rolling roller 64 and the lower rolling roller 72 respectively;
S2, a servo motor 65 drives an upper rolling roller 64 to rotate, the upper rolling roller 64 drives a cleaning mechanism 9 to rotate through a belt 10, so that brushes 942 on the cleaning mechanism 9 are in contact with the lower end surface of a copper strip 11 and the upper end surface of an aluminum strip 12 for cleaning, meanwhile, high-pressure gas is filled into an air inlet ring seat 962 through an air inlet hose 962, sequentially enters a channel in the H-shaped frame 911 through an air inlet hole 9643, an air collection cavity 9644 and a plug tube 9640, and finally is sprayed out through a spray head 912, so that the lower end surface of the copper strip 11 and the upper end surface of the aluminum strip 12 are cleaned again;
S3, the servo motor 65 drives the upper rolling roller 64 to rotate, so that the copper strip 11 and the aluminum strip 12 are rolled into a copper-aluminum composite strip through the upper rolling roller 64 and the lower rolling roller 72.
Specifically, in use, the cleaning mechanism 9 is positioned between the left side of the copper strip 11 and the aluminum strip 12, so that the brushes 942 on the cleaning mechanism 9 contact the lower end surface of the copper strip 11 and the upper end surface of the aluminum strip 12;
The copper strip 11 is then passed between the first guide roller 82 and the second guide roller 83, the aluminum strip 12 is passed between the third guide roller 84 and the fourth guide roller 85, and then the rear ends of the copper strip 11 and the aluminum strip 12 are passed between the upper rolling roller 64 and the lower rolling roller 72, respectively;
Since the second rotating shafts 69 at the two ends of the upper rolling roller 64 are movably connected to the lower side between the rear vertical parts of the rotating arms 61, the third gear 63 (the third gear 63 is positioned at the inner side of the right rotating arm 61) fixed at the right end of the second rotating shaft 69 is meshed with the fourth gear 62 at the output end of the servo motor 65, and then the servo motor 65 drives the upper rolling roller 64 and the second rotating shaft 69 to rotate anticlockwise through the fourth gear 62 and the third gear 63;
Because the left end of the second rotating shaft 69 is fixedly connected with the first belt pulley 70 after penetrating and extending through the arc-shaped groove 101, the second belt pulley 961 is connected with the first belt pulley 70 through the belt 10, the upper rolling roller 64 rotates, the upper rolling roller 64 drives the cleaning mechanism 9 to rotate through the belt 10, so that brushes 942 on the cleaning mechanism 9 are in contact with the lower end surface of the copper strip 11 and the upper end surface of the aluminum strip 12 for cleaning, meanwhile, high-pressure gas is filled into the air inlet ring seat 962 through the air inlet hose 962, and sequentially enters a channel in the H-shaped frame 911 through the air inlet hole 9643, the air collecting cavity 9644 and the plug tube 9640, and finally the high-pressure gas is sprayed out through the spray head 912, so that the lower end surface of the copper strip 11 and the upper end surface of the aluminum strip 12 are cleaned again;
removing oxides, dirt and impurities on the lower end surface of the copper strip 11 and the upper end surface of the aluminum strip 12 to ensure the joining quality;
The servo motor 65 drives the upper rolling drum 64 to rotate so that the copper strip 11 and the aluminum strip 12 are rolled into a copper-aluminum composite strip by the upper rolling drum 64 and the lower rolling drum 72. (copper strip 11 and aluminum strip 12 are heated and then hot rolled using upper and lower rolls 64 and 72 to laminate copper strip 11 and aluminum strip 12 together.)
The piston rod at the output end of the hydraulic cylinder 77 is extended, so that the movable frame 71 moves backwards along the guide rail 32, at this time, since the first gear 76 is meshed with the tooth 74 on the horizontal part at the front end of the movable frame 71, the first gear 76 rotates anticlockwise, and since the second gear 67 is meshed with the upper end of the corresponding first gear 76, the second gear 67 rotates clockwise under the drive of the first gear 76;
Because the second gear 67 is fixed on the outer side of the front end of the rotating arm 61, and the first rotating shaft 68 fixed in the middle of the outer side of the second gear 67 is movably connected to the inner wall of the corresponding vertical plate 1, when the second gear 67 rotates clockwise with the first rotating shaft 68 as the center of a circle, the rotating arm 61 drives the upper rolling roller 64 to rotate clockwise with the first rotating shaft 68 as the center of a circle, so that the position of the upper rolling roller 64 is adjusted in a rotating way (at this time, the second rotating shaft 69 slides correspondingly in the arc-shaped groove 101), the distance between the upper rolling roller 64 and the lower rolling roller 72 is reduced, the rolling pressure of the upper rolling roller 64 and the lower rolling roller 72 on the copper strip 11 and the aluminum strip 12 is increased, and the copper strip 11 and the aluminum strip 12 are stacked after hot rolling;
Because the second rotating shaft 69 correspondingly slides in the arc-shaped groove 101, the distance between the first belt pulley 70 and the second belt pulley 961, which are fixed at the left end of the second rotating shaft 69, is changed, so that the belt 10 between the first belt pulley 70 and the second belt pulley 961 is not tensioned any more, and the transmission between the first belt pulley 10 and the second belt pulley 961 is affected;
At this time, by the arrangement of the tensioning mechanism 2, the sliding seat 24 on the tensioning mechanism moves under the action of the elastic force of the second spring 27, so that the upper tensioning wheel 25 and the lower tensioning wheel 25 are clung to the inner wall of the middle part of the belt 10, the belt 10 is always in a tensioning state, and the cleaning mechanism 9 is rotated while the servo motor 65 is ensured to drive the upper rolling roller 64 to rotate.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
