One end of the bidirectional screw 24 is fixedly connected to the worm wheel of the worm gear 25. A micro motor 26 is fixedly connected to the worm of the worm gear 25 at the top of the punching plate 21. The output end of the micro motor 26 is fixedly connected to the top of the worm of the worm gear 25. A through groove 231 is opened at the bottom of the guide rail 23, and positioning holes 232 are evenly spaced on both side walls of the through groove 231.

The locking member 41 includes a U-shaped plate 411 fixedly connected to the top of the punch head 4, a "J"-shaped rod 412 is rotatably arranged between the inner walls of the U-shaped plate 411, a connecting rod 413 is movably sleeved on the protruding outer wall of the "J"-shaped rod 412, a moving rod 414 is movably connected to the top of the connecting rod 413, the moving rod 414 passes through the top plate of the U-shaped plate 411 and an electromagnet 415 is fixed to the rear end, both ends of the "J"-shaped rod 412 pass through and extend to the outside of the side plate of the U-shaped plate 411 and are respectively fixedly connected to the rear ends of the adjusting rods 416, a spiral groove 4161 is opened on the outer wall of the adjusting rod 416, a positioning cylinder 417 is sleeved on the outer wall of the end of the adjusting rod 416, a hemisphere 4171 engaged in the spiral groove 4161 is processed on the inner wall of one side of the port of the positioning cylinder 417, and a telescopic rod 418 is fixedly connected between the positioning cylinder 417 and the side wall of the U-shaped plate 411.

[0021] The positioning tube 417 is arranged corresponding to the positioning hole 232. When the raised end of the "X"-shaped rod 412 is vertically upward, the positioning tube 417 is completely fitted on the outer wall of the adjusting rod 416, and the end of the positioning tube 417 is suspended in the through groove 231.

On the contrary, the lower end of the electromagnet 415 rests on the top of the U-shaped plate 411, and the end of the positioning tube 417 is inserted into the positioning hole 232.

[0022] The punch head 4 includes a U-shaped holder 42 movably engaged with the outer wall of the guide rail 23 and a punch body 43 fixedly connected to the top of the U-shaped holder 42.

[0024] like Figure 1-3 As shown, a collecting cavity 101 is arranged inside the machine base 1 below the punching hole 3, and a guide plate 102 is fixedly and obliquely arranged between the side walls at both ends of the collecting cavity 101, and a guide inclined plate 103 is fixedly and obliquely arranged on the top of both sides of the bottom of the guide plate 102 in an inverted eight-shaped shape, and a discharge hopper is arranged on the side wall of one end of the collecting cavity 101 at the inclined lower end of the guide inclined plate 103. The small materials cut off from the electromechanical sheet after punching leak from the punching hole 3 into the collecting cavity 101, slide along the inclined surface of the guide plate 102, and are guided and gathered by the guide inclined plate 103 to be concentrated at the port of the discharge hopper for discharge. It only needs to place a receiving bucket at the bottom of the discharge hopper to collect and process the small materials of the punched sheet, so as to avoid the small materials of the sheet falling to the ground and affecting the environmental hygiene and production operation safety.

[0025] Slide grooves 104 are evenly spaced apart on the top of the machine base 1 adjacent to both sides of the punching hole 3, and a slider is movably arranged in the slide groove 104. A calibration angle iron 105 is fixedly connected to the top of the slider, and an electric push rod 106 is fixedly connected to the side wall of the slider away from the punching hole 3. The end of the electric push rod 106 is fixedly connected to the inner wall of the end of the slide groove 104. The electric push rod 106 is used to push the calibration angle iron 105 to fit the outer walls of both sides of the end of the electromechanical plate to be processed, and the triangular characteristics of the calibration angle iron 105 are used to limit the plate so that it can be stably maintained above the punching hole 3 without deviation.

[0026] In this embodiment, the electromechanical product sheet to be punched is placed on the top of the machine base 1 at the punching hole 3, and after being fixed, the hydraulic rod 22 is used to push the punching plate 21 downward, so that the punching plate 21 drives the punching head 4 at the bottom of the guide rail 23 to press down on the punching hole 3, so that the punching head 4 is used to punch the sheet. When it is necessary to punch holes in different parts of the same sheet, two groups of hydraulic rods 22 and the punching head 4 can be started at the same time to press down and punch. When punching holes in sheets of different specifications, the electromagnet 415 is started, and the electromagnet 415 is energized to obtain magnetic force and adsorb At the lower end of the top plate of the through slot 231 at the lower end of the guide rail 23, the electromagnet 415 drives the moving rod 414 to move upward during adsorption, and the moving rod 414 cooperates with the connecting rod 413 to drive the ""-shaped rod 412 to rotate nearly 180 degrees in the U-shaped plate 411, so that the ""-shaped rod 412 protrudes and rotates to the top. When the ""-shaped rod 412 rotates, the spiral groove 4161 on the outer wall of the adjusting rod 416 caters to the hemispherical body 4171 on the inner wall of the port side of the positioning tube 417 to rotate. When rotating, due to the restriction of the telescopic rod 418 on the positioning tube 417, it moves horizontally and is pulled out of the guide rail 23. The positioning hole 232 on the side wall is completely fitted on the outer wall of the end of the adjusting rod 416 to automatically release the restriction on the punch head 4. At this time, the micro motor 26 is started to cooperate with the worm gear 25 to drive the bidirectional screw 24 to rotate, and the bidirectional screw 24 cooperates with the positioning sleeve 44 to push the two groups of punch heads 4 to slide left and right on the outer wall of the guide rail 23, so as to adjust the operating distance of the punch head 4 to adapt to the punching processing requirements of plates of different sizes. After the punch head 4 is adjusted, the electromagnet 415 is powered off. Under the gravity of the electromagnet 415 and the "J"-shaped rod 412, the "J"-shaped rod 41 The raised part is automatically deflected downward, so that the raised part is vertically downward. When the "X"-shaped rod 412 rotates, the spiral groove 4161 cooperates with the hemispherical body 4171 to push the positioning cylinder 417 in the opposite direction, so that the positioning cylinder 417 fitted on the outer wall of the end of the adjusting rod 416 is pulled outward, so that the end is inserted into the positioning hole 232 again. The punching head 4 is automatically locked through gravity adjustment to avoid shaking and instability when punching the plate. It is convenient and quick to use, and avoids the problem of inconvenience in operation when the transmission equipment uses the moving plate to punch different parts when the plate area is too large.

[0027] According to another embodiment of the present invention, Figure 1 , Figure 2 -and Fig.10 An extended support plate is integrally formed on the side wall of the machine base 1 outside the four-column bracket 2, and a plate arrangement box 5 is fixedly arranged on the top of the extended support plate. The electromechanical product plates to be processed are stacked inside the plate arrangement box 5, and a pneumatic push rod 6 is fixedly arranged on the top of the extended support plate outside the plate arrangement box 5. A feeding push plate 7 is fixedly connected to the end of the pneumatic push rod 6. A through opening is arranged at the bottom of the plate arrangement box 5 corresponding to the feeding push plate 7, and the bottom plate of the plate arrangement box 5 in the through opening is an open structure.

[0028] Deflection pressure rods 51 are movably connected to the inner walls of both sides of the plate arrangement box 5 at even intervals, and strip holes 52 are opened on the side walls of the deflection pressure rods 51. Limit rods 53 are movably engaged in the strip holes 52. The ends of the limit rods 53 on the same side of the plate arrangement box 5 are fixedly connected to the same counterweight rod 54. The gravity of the counterweight rod 54 is much greater than the total gravity of the plates. Rotating drums 55 are movably arranged on the inner walls of both sides of the plate arrangement box 5 between the counterweight rods 54 at even intervals, and loading plates 56 are fixedly connected to the side walls of the rotating drum 55 at even intervals. The loading plates 56 on both sides of the plate arrangement box 5 are horizontally layered to carry the materials to be loaded. The electromechanical product plate of the worker, and the bottom of the counterweight rod 54 is fixedly connected to the limit plate 57, and the inner wall of the inner groove port at the bottom of both sides of the plate arrangement box 5 is fixedly connected with a convex plate supporting the limit plate 57, and a self-locking stepper motor 58 is fixedly installed on the inner groove bottom plate below the convex plate, and a cam 581 is fixedly connected to the output end of the self-locking stepper motor 58. The model and power of the self-locking stepper motor 58 are exactly the same. The rotation drive directions of the two groups of self-locking stepper motors 58 are opposite, and they run synchronously under the action of the controller to ensure the synchronous rotation of the rotating drums 55 on both sides of the plate arrangement box 5.

[0029] When the end of the deflection pressure rod 51 is tilted and rests on the top of the end of the horizontal loading plate 56 of the rotating drum 55, the limiting rod 53 is engaged with the end of the inclined lower end of the strip hole 52. At this time, the lower end of the limiting plate 57 is attached to the top of the convex plate on the inner wall of the inner groove port at the bottom of both sides of the plate arrangement box 5.

[0030] In this embodiment, the electromechanical product plates to be processed are stacked in sequence on the loading plates 56 between the side walls of the rotating drum 55 in the plate arrangement box 5. The loading plates 56 on the outside of the rotating drum 55 lift the bottoms of the two ends of the electromechanical product plates to be processed so that they are stacked in layers. When processing is required, the controller intermittently starts the self-locking stepper motor 58 to rotate, and the self-locking stepper motor 58 drives the cam 581 to rotate intermittently. When the cam 581 rotates, it pushes the limit plate 57 upward, and the limit plate 57 pushes the counterweight rod 54 to move upward. The counterweight rod 54 uses the limit rod 53 and the strip hole 52 to push the deflection pressure rods 51 on the inner walls on both sides of the plate arrangement box 5 to rotate counterclockwise and clockwise respectively, so as to simultaneously release the restrictions of the horizontal loading plates 56 on the side walls of the rotating drum 55 on both sides of the plate arrangement box 5. The rotating drum 5 The plates between the loading plates 56 automatically rotate inwards under the gravity of the plates. After the drum 55 rotates 90 degrees, the upper plates automatically fall onto the next loading plate 56 at the lower layer. As the plates fall, the counterweight rod 54 moves downward again under the gravity, thereby driving the deflection pressure rod 51 to deflect and move downward in the opposite direction, so that it can press the horizontal loading plate 56 that receives the plates again, preventing the drum 55 from excessively rotating and continuing to unload the plates. The plates on the initial lower loading plate 56 fall onto the top of the frame through the bottom port of the loading plate 56. The pneumatic push rod 6 extends and pushes the feeding push plate 7 to push the fallen plates, so that they slide to the punching hole 3 for punching. In this way, the stacked plates are unloaded intermittently and uniformly in turn, realizing the continuous automatic feeding process of the electromechanical product plate punching processing, which is convenient to use.

[0031] The technical scope of the present invention is not limited to the contents in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
