In the embodiment of the invention, the working principle of the L-shaped profile punching device is as follows:

firstly, the L-shaped section 10 is transported to the punching platform 101, one side of the L-shaped section 10 is inserted into the limiting groove, the other side of the L-shaped section 10 is attached to the upper surface of the punching platform 101, then the electromagnet 9 is electrified, one side of the L-shaped section 10 is adsorbed on the groove wall of the limiting groove, because the width of the limiting groove is larger than that of one side of the L-shaped section 10 for facilitating the insertion of one side of the L-shaped section 10 into the limiting groove, the electromagnet 9 is arranged, thus the influence of the spacing of the limiting groove is eliminated, then, the punching cylinder 1 acts, the punching cylinder 1 drives the moving plate 2 to integrally descend, in the descending process of the moving plate 2, the pressing plate 6 firstly presses the other side of the L-shaped section 10, the L-shaped section 10 realizes the complete pressing and limiting, after the pressing plate 6 presses, the moving plate 2 continues to descend, the spring 62 is further compressed, and simultaneously, while, under the action of the left rack 51 and the right rack 52 on the upright 5, the left gear 31 and the right gear 32 in the moving plate 2 rotate around their axes, further, the right gear 32 rotates to drive the right plunger 42 to further move downwards along the moving plate 2, so that the first punch 421 on the right plunger 42 can punch the other side of the L-shaped profile 10, meanwhile, the left gear 31 rotates to drive the left plunger 41 to further move downwards along the moving plate 2, the inclined block 411 pushes the inclined slider 7 to slide upwards in the punching table 101, the rack part 72 on the inclined slider 7 drives the engaging gear 81 to rotate, the engaging gear 81 drives the rotating wheel 83 to deflect with a certain radian through the intermediate gear 82, the second punch 831 on the rotating wheel 83 punches one side of the L-shaped profile 10, thereby completing the punching of the two sides of the L-shaped profile 10, after the punching is completed, the punching cylinder 1 is reset, the pressing plate 6 moves upwards, the moving plate 2 moves upwards synchronously, the left gear 31 and the right gear 32 rotate reversely, the left plunger 41 and the right plunger 42 slide upwards synchronously along the moving plate 2, the first punch 421 leaves the L-shaped section 10, meanwhile, the inclined slider 7 loses the pushing action of the inclined block 411, the inclined slider 7 abuts against the blocking part 102 of the punching table 101 under the action of self gravity, in the downward sliding process of the inclined slider 7, the rotating wheel 83 rotates reversely under the action of the meshing gear 81 and the middle gear 82, the second punch 831 on the rotating wheel 83 also leaves the L-shaped section 10, the electromagnet 9 loses power, the punched L-shaped section 10 is taken out, and therefore the whole continuous punching process is completed.

In summary, after the L-shaped profile 10 is inserted into the limiting groove of the punching table 101, the pressing plate is firstly pressed onto the L-shaped profile to press and position the L-shaped profile 10, and then the first punch 421 punches the other side of the L-shaped profile 10, and at the same time, along with the synchronous descending of the inclined block 411, the inclined block 411 pushes the inclined slide block 7 to move upwards to drive the engaging gear 81 to rotate, the engaging gear 81 finally drives the rotating wheel 83 to rotate through the intermediate gear 82, and the second punch 831 on the rotating wheel 83 punches one side of the L-shaped profile 10, so that the automatic punching of the L-shaped profile 10 is realized, the processing efficiency of punching the L-shaped profile 10 is improved, and the processing risk is reduced.
