As an embodiment of the present invention, as shown in fig. 1 to 2, a T-shaped block 9 is fixedly connected to a position, close to the middle, of the left outer surface of the rack 595, a T-shaped groove 10 is formed in both side positions of the right outer surface of the U-shaped stamping main body 1, and the T-shaped block 9 slides inside the T-shaped groove 10.

When the solar panel works, the rack 595 is fixedly connected with the panel body 4, and the rack 595 is used for rotating the second gear 54, when the solar panel is pressed down, the rack 595 is easy to shake, and the second gear 54 can be damaged.

The using method comprises the following steps: firstly, the hydraulic rod 2 presses the upper die holder 3 downwards to move, the plate body 4 is driven to move downwards while moving, the rack 595 is fixed at the lower end of the plate body 4, the rack 595 and the second gear 54 are meshed to rotate, the connecting rod 55 also rotates when the second gear 54 rotates, and then the first gear 51 is driven to rotate, the first gear 51 is connected with the second gear 54 through the connecting rod 55, so that when the second gear 54 rotates, the first gear 51 can also rotate simultaneously, the connecting rod 55 can be supported and fixed by the supporting plate 52, the connecting rod 55 is convenient to rotate, then the pushing toothed rod 56 with meshed lower end is driven to move towards one side of the lower die holder 8 when the first gear 51 rotates, so that the pushing toothed rod 56 pushes the top plate 58 to move towards one side of the lower die holder 8, at this time, the upper die holder 3 presses the die plate on the lower die holder 8 to form, at the same time, the top plate 58 moves towards one side of the lower die holder 8 and then laterally flanging the pressed die, and then simultaneously punching and flanging the two sides of the die when the upper die holder 3 is pressed down, the structure effectively improves the working efficiency of a user and improves the production rate, the rack 595 can be clamped in the T-shaped groove 10 by using the T-shaped block 9, so that the stability of the rack 595 is effectively improved, further the damage to the second gear 54 caused by the shaking of the rack 595 can be prevented, the safety is improved, when the user needs to disassemble the top part 61 at the later stage, the fixing screw 63 is firstly twisted out from the threaded hole 62 and the threaded groove 593, then the top part 61 slides out from the sliding groove 592, so that the top part 61 is disassembled and replaced, then when the top part 61 with the T-shaped structure is installed, the top part 61 slides into the sliding groove 592 by using the T-shaped block 61, the top part 61 is fixed in the threaded groove 593 and the threaded hole 62 and the sliding groove 592, therefore, the installation of the top part 61 is realized, the installation and disassembly speed is further improved, the production efficiency is improved, by utilizing the matching between the first clamping groove 594 and the first clamping block 64, when a user slides the top part 61 into the sliding groove 592, the first clamping block 64 is attached to the outer surface of the top part 61, so that the friction force between the top part 61 and the sliding groove 592 is reduced, the installation of the top part 61 is facilitated, in the use process, the user drops protective oil on the upper end of the push rack rod 56, the protective oil can be smeared on the first gear 51 when the push rack rod 56 is meshed with the first gear 51, the service life of the protective device can be prolonged, the maintenance cost is reduced, when the fixing rod 57 slides in the second sliding groove 71, the friction force between the fixing rod 57 and the second sliding groove 71 is reduced, and then the protective oil flows into the diversion groove 73 by utilizing the first through hole 72, then, the protective oil flows to the surface of the second fixture block 76 from the guide groove 73 through the second through hole 74, so that the second fixture block 76 is coated with the protective oil, the service life is prolonged, and the maintenance cost is reduced.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
