s3, punching an outer frame on the inner frame which is flattened in the step S2 by using the outer cutter die 7, similarly, the outer cutter die 7 is contacted with the punched inner frame, a tensioning mechanism arranged on the mounting seat 5 where the outer cutter die 7 is arranged is firstly contacted with the surface of the aluminum foil, then the aluminum foil is tensioned along with the descending of the mounting seat 5, and then the punching process is carried out;
and S4, repeatedly rolling the punched outer frame surface by using a flattening mechanism, thereby further ensuring that the high-temperature adhesive and the aluminum foil piece are adhered more precisely.
The working principle is as follows: when punching, the aluminum foil coated with high-temperature glue firstly passes through the inner cutter die 6, then the first hydraulic cylinder 3 extends to enable the mounting seat 5 provided with the inner cutter die 6 to descend until the tensioning mechanism on the mounting seat 5 is firstly contacted with the aluminum foil coated with high-temperature glue, at the moment, along with the continuous descending of the mounting seat 5, the connecting rod 13 in the tensioning mechanism gradually expands outwards so as to drive the tensioning roller 14 to roll on the surface of the aluminum foil, so that the aluminum foil is stretched outwards and tensioned, the rotating shaft 16 rotates along with the connecting rod 13 in the outward tensioning process, one end of the positioning column 21 positioned in the mounting frame 15 also slides on the surface of the abutting wheel 19, the positioning column 21 gradually moves towards the inside of the mounting frame 15 under the action of the elastic sheet 23, and when the other end of the positioning column 21 exits to the outside of the positioning hole 20, the connecting rod 13 is abutted against the inner wall of the top of the mounting frame 15 to be incapable of continuously rotating, at this time, the torsion spring 34 is also twisted tightly, the mounting frame 15 starts to move upwards as the mounting base 5 continues to descend, the return spring starts to be compressed, the aluminum foil is tensioned and does not continue to be tensioned as the mounting base 5 descends, until the aluminum foil is punched by the inner cutting die 6, after punching is completed, the first hydraulic cylinder 3 contracts, the mounting base 5 moves upwards, the mounting frame 15 starts to move downwards under the action of the return spring 18, the tensioning roller 14 throws away and abuts against the surface of the aluminum foil, so that the aluminum foil is prevented from being adhered to the inner cutting die 6 until the bottom of the mounting frame 15 abuts against the bottom of the mounting groove 17, then as the mounting base 5 continues to move upwards, the bottom of the abutting column 8 abuts against the top surface of the connecting rod 13, so that as the mounting base 5 moves upwards, the connecting rod 13 is abutted by the abutting column 8 and rotates downwards until the abutting wheel 19 abuts against the positioning hole 20 from one end of the positioning column 21, and when the inner frame is punched, the flattening mechanism installed on the installation base 5 works simultaneously, the installation base 5 moves downwards to drive the fixing plate 25 in the flattening mechanism to move downwards, so that the fixing base 10 descends, the pressing roller 9 presses the surface of the inner frame punched in the upward moving step while the fixing base 10 moves downwards, then in the process of continuing descending of the fixing base 10, the gear 30 moves downwards in the fixing frame 11, so that the gear 30 is respectively meshed with the racks 24 on the inner walls of the two sides of the fixing frame 11, the gear 30 can rotate in different directions in the descending process, the threaded column 29 is driven to rotate in different directions, the moving plate 26 moves left and right in a reciprocating manner, and finally the pressing roller 9 rolls on the surface of the inner frame in a reciprocating manner, so that the bonding between the aluminum foil and the high-temperature adhesive is more compact, and then the installation base 5 provided with the outer cutting die 7 descends to perform outer frame punching, and after the outer frame is punched, the flattening mechanism arranged on the mounting seat 5 flattens the outer frame part, and the steps are the same as the steps for flattening the inner frame.
