[0043] The punching device 4 includes a positioning support 42, a second fixed guide seat 41 for guiding is fixedly provided on the inner end surface of the positioning support 42, and a transmission turntable 48 is rotatably clamped on the inner end surface of the positioning support 42, a transmission rocker 46 is fixedly provided on the inner end surface of the transmission turntable 48, and fourth synchronous pulleys 47 are provided on both side ends of the transmission turntable 48, the inner end surface of the positioning support 42 is slidably clamped with a guide rail 45 through the transmission rocker 46, and a rocker guide groove 43 is opened at the center of the inner end surface of the guide rail 45, and four groups of punching tools 44 are equidistantly provided on the lower end surface of the guide rail 45.

[0044] The sides of the two groups of guide rollers 25 rotate synchronously in opposite directions through the meshing connection of the transmission gears 24, and the inner walls of the guide rollers 25 are squeezed and fitted with the outside of the aluminum ladder workpiece 1, which can effectively improve the stability of the subsequent multiple groups of guide rollers 25 in feeding the aluminum ladder workpiece 1. The feeding chute 23 is directly opposite to the supporting sleeve 31, and the supporting sleeve 31 and the feeding chute 23 are both slidably engaged with the aluminum ladder workpiece 1. The aluminum ladder workpiece 1 can be guided by the feeding chute 23 under the rolling feeding of the guide rollers 25 and finally introduced into the interior of the supporting sleeve 31, which is convenient for subsequent quick and convenient punching.

[0045] The first synchronous pulley 10 is meshed and connected with the third synchronous pulley 312 through the motor holder 5, and the second synchronous pulley 38 is meshed and connected with the fourth synchronous pulley 47 through the second synchronous belt 8, so that the material guiding device 3 and the punching device 4 can operate synchronously, thereby maximizing the coordination between the punching and feeding of the equipment, and also improving the efficiency of the power utilization of the equipment. The punching tool 44 is slidably connected to the front of the first fixed guide seat 21 through the punching guide groove 22. The punching guide groove 22 can provide sufficient guiding foundation for the punching tool 44, thereby improving the accuracy and stability of the subsequent punching of the aluminum ladder workpiece 1 inside the support sleeve 31 by the punching tool 44.

[0046] The notched disc 39 is adapted to the toggle slide 37 through the guide arm 310, thereby intermittently driving the groove wheel 36 to flip 90 degrees, and the notched disc 39 is rotationally connected with the groove wheel 36 through the groove wheel slot 35. When unloading the aluminum ladder workpiece 1 after punching, the guide arm 310 can limit the sliding position with the toggle slide 37, thereby driving the groove wheel 36 and multiple sets of adjustment chucks 32 to flip 90 degrees, which can not only make a new set of support sleeves 31 face the loading chute 23 for loading, but also automatically unload the processed aluminum ladder workpiece 1 by gravity, effectively improving the degree of automation of the equipment. When punching, the notched disc 39 can be limited for a long time by the side wall of the original disc and the groove wheel slot 35, which can provide sufficient guiding time for the punching of the punching tool 44.

[0047] The edges and corners of the four groups of limit support plates 331 are all fitted and clamped with the inner wall edges and corners of the aluminum ladder workpiece 1, and the guide slide 332 is slidably clamped in the inside of the alignment clamp 334 through the linear slide groove 335. The transmission turntable 48 is adapted to the transmission rocker 46 through the rocker guide groove 43, thereby driving the guide slide 45 to cyclically move up and down outside the second fixed guide seat 41. When the aluminum ladder workpiece 1 is limited and supported, the edges and corners of the four groups of limit support plates 331 can coincide with the internal edges and corners of the aluminum ladder workpiece 1, thereby improving the stability of the support during punching of the aluminum ladder workpiece 1. The linear slide groove 335 can provide sufficient linear guiding foundation for the guide slide 332, and at the same time, the arc guide groove 337 can provide sufficient centripetal guiding foundation for the guide slide 332, which is convenient for stepless control of the supporting side length of the limit support plate 331, thereby improving the adaptability of the equipment.

[0048] Working principle: Before use, the staff can guide the multiple groups of aluminum ladder workpieces 1 to be punched into the loading chute 23 inside the first fixed guide seat 21, and then start the reduction motor 26. At this time, the reduction motor 26 can drive the multiple groups of guide rollers 25 to rotate synchronously in the opposite direction through the two groups of transmission gears 24, so as to cyclically guide the four groups of aluminum ladder workpieces 1 into the support shell 31. At the same time, the protective device 33 can support the inner wall of the aluminum ladder workpiece 1 to prevent deviation during subsequent punching, thereby improving the accuracy of subsequent punching and positioning;

[0049] When punching the aluminum ladder workpiece 1, the staff can start the dual-axis motor 7. At this time, the dual-axis motor 7 can synchronously drive the transmission guide shafts 9 at both ends to rotate. The two sets of transmission guide shafts 9 can synchronously drive the first synchronous pulleys 10 on both sides to rotate. The two sets of first synchronous pulleys 10 can synchronously drive the third synchronous pulley 312 to rotate through the first synchronous belt 6. When the third synchronous pulley 312 rotates, the third synchronous pulley 312 can synchronously drive the notched disc 39 and the second synchronous pulley 38 to rotate. When the second synchronous pulley 38 rotates, the second synchronous pulley 38 The pulley 38 can synchronously drive the fourth synchronous pulley 47 to rotate through the second synchronous belt 8. At this time, the fourth synchronous pulley 47 can drive the transmission swing rod 46 to rotate in a circle through the transmission turntable 48. At the same time, the transmission swing rod 46 can slide and limit with the guide rail 45, so that the guide rail 45 can drive the punching tool 44 to move up and down cyclically outside the second fixed guide seat 41. When the punching tool 44 moves downward, the punching tool 44 can be guided by the punching guide groove 22, and then punch the aluminum ladder workpiece 1 that is limited by the support shell 31 and the protective device 33;

[0050] When the punching tool 44 punches the aluminum ladder workpiece 1, the notched disc 39 can rotate synchronously with the second synchronous pulley 38. At this time, the disc side wall of the notched disc 39 can be limited by the groove wheel slot 35, so that during the punching process of the punching tool 44 from top to bottom, the notched disc 39 can keep the groove wheel 36, the transmission shaft 34 and the multiple groups of steering chucks 32 stationary through the groove wheel slot 35, thereby improving the stability of the post-punching. When the punching tool 44 is reset after the punching is completed, the guide inside the notched disc 39 is The guide arm 310 just rotates to the toggle slot 37 inside the groove wheel 36, and the guide arm 310 can drive the groove wheel 36 to rotate 90 degrees through the toggle slot 37, so that the groove wheel 36 can drive the multiple sets of direction adjustment chucks 32 and the aluminum ladder workpiece 1 punched therein to flip 90 degrees through the transmission clamp shaft 34. The aluminum ladder workpiece 1 punched is now at the bottom of the direction adjustment chuck 32, and then falls down by gravity. At the same time, a new set of support shells 31 is directly opposite to the feeding chute 23, which is convenient for subsequent cyclic punching.

[0051] If it is necessary to perform punching limit protection operations on aluminum ladder workpieces 1 with different side lengths, the stepper motor 336 can be started at this time. The stepper motor 336 can drive the positioning chuck 333 to rotate. The positioning chuck 333 can be limited by the arc guide groove 337 and the guide slide 332, and then synchronously drive the four groups of limit support plates 331 to perform synchronous centripetal and centrifugal displacement. The four groups of limit support plates 331 can support the inner walls of the aluminum ladder workpieces 1 with different side lengths to prevent the incision from being offset when the punching tool 44 is punching, thereby affecting the accuracy of punching.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
