The upper end of the connecting suspension rod 82 movably extends to the inside of the top plate of the stamping seat 4, and its bottom end is fixedly connected to the top of the mounting suspension plate 6. A positioning ring 83 is fixedly connected to the bottom plate of the inner cavity of the positioning sleeve 81. The positioning ring 83 is movably sleeved on the outer wall of the connecting suspension rod 82, and the positioning ring 83 is movably provided with deflection limit rods 84 at even intervals. A torsion spring is provided on the side wall at the bottom of the deflection limit rod 84, and the other end of the torsion spring is connected to the bottom plate of the groove at the top of the positioning ring 83. A limiting groove 85 is provided on the outer wall of the connecting suspension rod 82 corresponding to the deflection limiting rod 84. When the torsion spring is normally relaxed, the protrusion of the deflection limiting rod 84 is suspended outside the end of the limiting groove 85. An inflation hood 86 is fixedly connected to the top of the positioning ring 83 outside the deflection limiting rod 84. The inflation hood 86 is wrapped around the outer wall of the connecting suspension rod 82 outside the deflection limiting rod 84. An adjusting air pump 87 is fixedly connected to the bottom plate of the inner cavity of the positioning sleeve 81 on one side of the inflation hood 86. A adjusting valve pipe 88 is fixedly connected to the side wall of the adjusting air pump 87. The end of the adjusting valve pipe 88 is communicated with the side wall of the inflation hood 86.

[0022] The feeding module 2 includes a mounting frame 21 fixedly connected to the top of the base 1 and an adjusting screw 22 movably arranged between the side walls at both ends of the mounting frame 21. The adjusting screw 22 is sleeved in a convex plate in a groove at the bottom of a raised support plate 23. The mounting frame 21 is a square frame structure. The two ends of the adjusting screw 22 are sleeved in bearings on the side walls at both ends of the mounting frame 21. When the raised support plate 23 is sleeved on the outer wall of the adjusting screw 22, the bottoms of the two ends of the raised support plate 23 are movably placed on the top of the mounting frame 21. A protective cover 24 is embedded on the raised side wall along the edge of the top of the raised support plate 23. A storage groove 25 is fixedly connected to the top of the protective cover 24. Clamping pieces 26 are evenly spaced and fixedly connected to the bottom plate of the storage groove 25. The clamping pieces 26 clamp the metal workpiece 3 through a pneumatic clamping arm. The storage groove 25 includes a reinforcing plate 251 fixedly connected to the top of the protective cover 24 and an isolation cover 252 fixed on the side wall at the top of the reinforcing plate 251 by a ring. The isolation cover 252 surrounds the outside of the clamping member 26 to block the flying metal chips. The clamping member 26 can be quickly disassembled and assembled. A discharge chute 253 is arranged inside the reinforcing plate 251. The bottom port of the discharge chute 253 extends to the side wall of the reinforcing plate 251, and its top port is arranged corresponding to the stamping positioning hole 261 on the bottom plate of the clamping member 26. When the stamping tool head 7 is subjected to the hydraulic rod 5 to stamp the metal workpiece 3, the stamping tool head 7 presses the stamping positioning hole 261 to squeeze the metal workpiece 3 to stamp and punch it, and the chips punched off the metal workpiece 3 fall from the stamping positioning hole 261 to slide into the discharge chute 253, and then fall into the waste box arranged on the base 1.

[0023] Specifically, the hydraulic rod 5 pushes the punching cutter head 7 to move downward to punch and cut the metal workpiece 3. The hydraulic rod 5 simultaneously drives the connecting hanger 82 by using the mounting hanger plate 6. By setting a detection device on the side wall of the punching cutter head 7, when it moves with the punching cutter head 7 and detects that the punching cutter head 7 is close to the operator's arm, a signal is transmitted to the controller. The controller controls the regulating air pump 87 to start. The regulating air pump 87 uses the regulating valve pipe 88 to evacuate the inflatable hood 86. After the inflatable hood 86 is evacuated, its volume shrinks and deforms to become smaller. After the inflatable hood 86 is shrunk, the deflection limit rod 84 is gathered to make it deflect close to the connecting hanger. 82. When the inflatable hood 86 is folded, the protrusion of the deflection limit rod 84 is engaged with the limit groove 85 on the side wall of the connecting suspension rod 82. At the same time, the top of the folded inflatable hood 86 also fits and restrains the connecting suspension rod 82. The inflatable hood 86 is wrapped and the deflection limit rod 84 restricts the limit groove 85, so that the connecting suspension rod 82 can be stopped from sliding down the positioning sleeve 81 in time, and then the connecting suspension rod 82 is used to cooperate with the installation hanger plate 6 to quickly stop the punching cutter head 7, so as to avoid the problem that the workers are distracted after working for a long time and are not responded to in time and are accidentally injured by the punching cutter head 7, thereby fully protecting the workers' operating safety.

[0024] Furthermore, in order to enhance the practicality of the punching tool head 7, it is convenient for punching holes of different sizes on the metal workpiece 3, such as Figure 3 and Figure 7-Figure 12 As shown, the following preferred technical solutions are provided: The punching cutter head 7 includes an adjusting box 71 fixedly connected to the bottom of the hydraulic rod 5 and a punching cutter 72 fixedly connected to the bottom of the adjusting box 71. Infrared detectors 73 are fixedly connected to the outer walls on both sides of the adjusting box 71. The infrared detector 73 is used to detect whether there is a worker's arm blocking the punching cutter 72. After detecting obstruction, a signal is transmitted to the controller to perform a movement stop operation. The adjusting box 71 is electrically connected to the controller on the side wall of the punching seat 4, which is used to switch and adjust the punching cutter 72.

[0025] The adjusting box 71 includes a connecting knife disc 711 and a mounting shell 712 fixedly connected to the side wall of the connecting knife disc 711, a driving gear 713 is movably provided at the middle part of the upper end of the connecting knife disc 711, a telescopic shaft rod 714 is movably penetrated and sleeved in the limiting hole 7131 in the middle of the driving gear 713, the lower end of the telescopic shaft rod 714 penetrates the connecting knife disc 711 and extends into the punching knife 72, and driven gears 715 are movably provided on the upper ends of the connecting knife discs 711 on both sides of the driving gear 713, and the driven gears 715 are meshed with the driving gear 713, an annular groove is provided on the top of the connecting knife disc 711, and the driving gear 713 and the bottom bosses of the driven gear 715 are movably engaged in the annular groove, and a moving screw rod 716 is movably sleeved in the threaded hole in the middle of the driven gear 715, and the lower end of the moving screw rod 716 penetrates the connecting knife disc 711 and is connected to the punching knife 72.

[0026] A partition plate 718 is fixedly connected between the inner wall of the mounting shell 712 at the upper end of the movable screw 716, a rotating motor is fixedly connected to the top of the partition plate 718, the bottom output end of the rotating motor is fixedly connected to the top of the telescopic shaft 714, and a power supply control module is provided on the upper end of the partition plate 718 on one side of the rotating motor, and the power supply control module is electrically connected to the rotating motor.

[0027] The telescopic shaft 714 includes a limiting sleeve 7141 movably sleeved in the limiting hole 7131 in the middle of the driving gear 713 and a moving clamping rod 7142 movably sleeved in the limiting sleeve 7141. The bottom of the moving clamping rod 7142 is provided with a limiting sleeve hole 7143. The moving clamping rod 7142 extends through and into the punching knife 72. The movable clamping sleeves on the side walls below the protrusions on both sides of the moving clamping rod 7142 are provided with limiting rings 7144. A connecting strip 7145 is fixedly connected to the outer wall of one side of the limiting ring 7144. The top of the connecting strip 7145 is fixedly connected to an electric lifting rod 7146. The top of the electric lifting rod 7146 is fixedly connected to the lower end of the connecting knife disc 711. When the electric lifting rod 7146 remains in a retracted state, the protrusions on both sides of the moving clamping rod 7142 are engaged in the limiting hole 7131 in the middle of the driving gear 713.

[0028] The punching knife 72 includes a first knife cylinder 721 fixedly connected to the bottom of the connecting knife disc 711 and a second knife cylinder 722 movably sleeved in the first knife cylinder 721. The two ends of the top of the second knife cylinder 722 are fixedly connected to the bottom of the moving screw 716. The thread rotation direction of the moving screw 716 is opposite, and the second knife cylinder 722 is synchronously pushed up and down. A third knife cylinder 723 is movably engaged in the sliding groove on the inner wall of the second knife cylinder 722. A fixing plate 724 is fixedly connected between the inner walls of the third knife cylinder 723. The fixing plate 724 is movably connected to the driving member 717 at the lower end of the connecting knife disc 711.

[0029] The driving member 717 includes a positioning screw 7171 that is movably inserted through the fixed plate 724 and a mounting ring 7172 that is movably clamped on the outer wall at the top of the positioning screw 7171.

The outer wall of one side of the mounting ring 7172 is fixedly connected to the elastic telescopic rod 7173, and the top of the elastic telescopic rod 7173 is fixedly connected to the bottom of the connecting knife disc 711.

[0030] Specifically, when it is necessary to perform punching operations of different sizes on the metal workpiece 3, when the hydraulic rod 5 drives the punching knife 72 to move directly downward, the diameter of the first knife cylinder 721 is the diameter of the punching hole of the metal workpiece 3. When it is necessary to punch a small hole on the metal workpiece 3, the rotating motor is started to drive the telescopic shaft 714 to rotate. The protruding portion of the moving clamping rod 7142 of the telescopic shaft 714 is engaged in the limiting hole 7131 in the middle of the driving gear 713, thereby driving the driving gear 713 to rotate. The driving gear 713 is simultaneously engaged to drive the two driven gears 715 to rotate. When the two driven gears 715 rotate, the threads drive the two moving screws 716 to move downward synchronously. The moving screws 716 push the second knife cylinder 722 to slide out of the port of the first knife cylinder 721. At this time, the diameter of the exposed second knife cylinder 722 is the diameter of the punching hole of the metal workpiece 3. When the second knife cylinder 722 slides out, the sliding groove on the inner wall presses and drives the third knife cylinder 723 to move downward synchronously to stretch the elastic telescopic rod 717. 3, so that the third knife cylinder 723 shrinks in the first knife cylinder 721 and moves downward synchronously. When it is necessary to punch a smaller diameter hole on the metal workpiece 3, the electric lifting rod 7146 is started to cooperate with the limiting ring 7144 and the connecting strip 7145 to drive the moving clamping rod 7142 in the limiting sleeve 7141 to move downward, and the moving clamping rod 7142 protrudes downward and disengages from the limiting hole 7131 in the middle of the driving gear 713, so as to fit on the top of the positioning screw 7171. When the rotating motor rotates, the positioning screw 7171 is driven to rotate by the cooperation of the limiting sleeve 7141 and the moving clamping rod 7142, so as to push the fixing plate 724 to drive the third knife cylinder 723 to slide out of the bottom port of the second knife cylinder 722, so as to complete the adjustment of the small-diameter knife cylinder. By switching and adjusting the knife cylinders of different diameters of the punching cutter 72, the punching operation of different diameters of the metal workpiece 3 is realized, avoiding the trouble of disassembling and replacing the knife head for punching holes in traditional equipment, saving the time of disassembling and assembling a large number of spirals during disassembly and assembly, and being convenient and fast.
