[0038] In the prior art, when punching, the hardware is directly placed on the base plate, and both the hardware and the base plate have smooth surfaces. If the hardware is thin-walled hardware, it is light in weight and is easily moved by external force during punching, resulting in the hardware being offset and the punching being inaccurate. Moreover, due to its light weight, it is easily lifted up by the punching machine body during punching, which is inconvenient for the next punching operation.

[0039] When the clamping mechanism provided by the present invention is in use, during the punching operation, the hardware needs to be placed on the conveying roller 11, and the handle 310 is rotated to drive the bidirectional ball screw 38 to rotate. Since a ball nut seat is provided at the connection between the bidirectional ball screw 38 and the movable plate 37, the radial movement of the movable plate 37 is ensured through the ball nut seat, and the bidirectional ball screw 38 drives the movable plate 37 to move in the opposite direction, and the movable plate 37 drives the rack 35 to move in the opposite direction, and the rack 35 drives the gear 34 to move in the opposite direction, and the gear 34 drives the rotating rod 31 to move in the opposite direction.

After the scanner 29 determines the punching position of the hardware, the signal is transmitted to the computer program, and the conveying roller 11 is controlled to stop moving by the computer program. After the punching head 28 punches a row of holes in the hardware, the conveying roller 11 will continue to be driven to transport the hardware until the scanner 29 determines the next punching position; the function of pressing and fixing hardware of different thicknesses is achieved.

[0040] like Figure 5 As shown, a reciprocating screw 22 is rotatably connected between the mounting plates 2 via bearings; a first motor 23 is fixedly connected to one side wall of the mounting plate 2, and the output shaft of the first motor 23 is fixedly connected to one end of the reciprocating screw 22; the moving block 24 is threadedly connected to the reciprocating screw 22; a first electric push rod 25 is fixedly connected to the bottom of the moving block 24; a mounting seat 26 is fixedly connected to the output end of the first electric push rod 25; a second motor 27 is fixedly connected to the mounting seat 26, and the output shaft of the second motor 27 is rotatably connected to the mounting seat 26 via bearings, and is fixedly connected to a punching head 28.

[0041] When the reciprocating screw 22 provided by the present invention is in use, the corresponding position of the punching hole is determined by the scanner 29 and the conveying roller 11, and then the first motor 23 is turned on, and the reciprocating screw 22 is driven to rotate by the first motor 23, and the moving block 24 is driven to move by the reciprocating screw 22, and the first electric push rod 25 is driven to move by the moving block 24, and the mounting seat 26, the second motor 27 and the punching head 28 are driven to move by the first electric push rod 25. Under the action of the first electric push rod 25 and the second motor 27, multiple punching holes are performed on the arranged hardware, and punching holes at different positions of the hardware in the horizontal and vertical directions has never been realized.

[0042] like Figure 1 and Figure 5As shown, a plurality of conveying rollers 11 are installed on the top of the workbench 1; a first discharge port 12 is opened on the top of the workbench 1, and the first discharge port 12 is directly opposite to the bottom of the punching head 28; a scanner 29 is fixedly connected to the center line of the side wall of the mounting seat 26, and the scanner 29 is electrically connected to the conveying rollers 11.

[0043] When the scanner 29 provided by the present invention is in use, the scanner 29 is used to scan the distance that the hardware moves under the action of the conveying roller 11, so as to determine the distance between two punching holes, and the scanner 29 is electrically connected to the conveying roller 11 to improve the stability and accuracy of the punching.

[0044] like Figure 4 As shown, two cross bars 39 are fixedly connected between the two fixed plates 36 ; and the movable plates 37 are slidably connected on the two cross bars 39 .

[0045] When the cross bar 39 provided by the present invention is in use, the movable plate 37 slides on the cross bar 39 during the movement, and the cross bar 39 limits the movable plate 37 in the horizontal direction.

[0046] like Figure 6 As shown, one end of the workbench 1 is fixedly connected to two fixed seats 5; each of the fixed seats 5 is fixedly connected to a sliding column 52; a lifting plate 51 is slidably connected to the two sliding columns 52; a cleaning brush is fixedly connected to the bottom of the lifting plate 51; the outer side of each sliding column 52 is sleeved with a first spring 53; the two ends of the first spring 53 are respectively fixedly connected between the bottom of the lifting plate 51 and the fixed seat 5.

[0047] When the lifting plate 51 provided by the present invention is in use, the punching of the hardware is completed, and the hardware waste falls through the first discharge port 12, and some debris splashes on the surface of the hardware. When the hardware is discharged, the cleaning brush cleans the debris on the surface of the hardware and drops it into the second discharge port 13; according to the different thicknesses of the hardware, when the hardware passes through the cleaning brush, the cleaning brush lifts the lifting plate 51 upward, and the lifting plate 51 slides on the sliding column 52. Under the action of the first spring 53, the lifting plate 51 is easy to quickly reset.

[0048] like Figure 1 and Figure 7 As shown, the side wall of the workbench 1 is symmetrically fixed with a second electric push rod 6, the output end of the second electric push rod 6 extends to the first discharge port 12, and is fixed with a mounting frame 61; the mounting frame 61 is rotatably connected to three limiting rollers 62 via roller shafts.

[0049] When the limiting roller 62 provided by the present invention is in use, when placing hardware, it is necessary to simultaneously open the two second electric push rods 6, drive the mounting frame 61 to move through the second electric push rods 6, drive the limiting roller 62 to move through the mounting seat 26, and fix the hardware in the center position through the limiting roller 62, so as to facilitate the scanning of the hardware by the scanner 29 and the accurate punching of the punching head 28.

[0050] like Figure 3 and Figure 8 As shown, the workbench 1 is provided with two slide grooves 72 ; the slide grooves 72 are connected to the first discharge port 12 ; the slide blocks 7 are slidably connected in the slide grooves 72 ; four second springs 71 are fixedly connected between the slide blocks 7 and the side walls of the slide grooves 72 .

[0051] When the slider 7 provided by the present invention is in use, the punching head 28 squeezes the slider 7 to both sides during the punching process, and the slider 7 slides in the slide groove 72 to compress the second spring 71. The slider 7 can not only serve as a supporting force for the bottom of the hardware, but also the punching waste can easily fall from between the sliders 7 without causing waste accumulation.

[0052] like Figure 3 As shown, the bottom of the workbench 1 is connected and fixedly connected with a first lower hopper 4 ; the first lower hopper 4 cooperates with the first discharge port 12 ; and a collection box 41 is provided below the first lower hopper 4 .

[0053] When the first lower hopper 4 provided by the present invention is in use, waste materials punched out by the hardware parts fall through the first lower hopper 4 and are then collected in the collection box 41 for easy recycling.

[0054] like Figure 3 As shown, a second discharge port 13 is provided at one end of the workbench 1, and the second discharge port 13 cooperates with a cleaning brush.

[0055] When the second discharge port 13 provided by the present invention is in use, the cleaning brush cleans the surface of the hardware and sweeps the debris on the surface of the hardware into the second discharge port 13 to prevent the debris from falling onto the workbench 1 and the ground to affect the working environment.

[0056] like Figure 3 As shown, the bottom of the workbench 1 is connected and fixedly connected with a second lower hopper 43 , the second lower hopper 43 cooperates with the second discharge port 13 , and a drainage trough 42 is connected and fixedly connected between the bottom of the second lower hopper 43 and the collecting box 41 .

[0057] When the drainage trough 42 provided by the present invention is in use, hardware debris falls into the second lower hopper 43 through the second discharge port 13, flows to the drainage trough 42 through the second lower hopper 43, and flows into the collection box 41 through the drainage trough 42, so as to collect hardware waste in a unified manner.

[0058] Working principle: When punching, the hardware needs to be placed on the conveying roller 11, and the handle 310 is rotated to drive the bidirectional ball screw 38 to rotate. Since a ball nut seat is provided at the connection between the bidirectional ball screw 38 and the moving plate 37, the ball nut seat ensures the radial movement of the moving plate 37. The bidirectional ball screw 38 drives the moving plate 37 to move in the opposite direction, and the moving plate 37 drives the rack 35 to move in the opposite direction, and the rack 35 drives the gear 34 to move in the opposite direction, and the gear 34 drives the rotating rod 31 to move in the opposite direction, and the rotating rod 31 drives the rotating rod 31 to move in the opposite direction. 1 drives the rotating frame 33 to move in the opposite direction, and drives the pressing roller 32 to move in the opposite direction through the rotating frame 33 until the pressing roller 32 contacts the surface of the hardware and stops rotating; the hardware is transported by the conveying roller 11, and scanned by the scanner 29. After the scanner 29 determines the punching position of the hardware, the signal is transmitted to the computer program, and the conveying roller 11 is controlled by the computer program to stop moving. After the punching head 28 punches a row of holes in the hardware, the conveying roller 11 will continue to be driven to transport the hardware until the scanner 29 determines the next punching position; the function of pressing and fixing hardware of different thicknesses is achieved;

[0059] The corresponding position of the punching hole is determined by the scanner 29 and the conveying roller 11, and then the first motor 23 is turned on, the reciprocating screw rod 22 is driven to rotate by the first motor 23, the moving block 24 is driven to move by the reciprocating screw rod 22, the first electric push rod 25 is driven to move by the moving block 24, and the mounting seat 26, the second motor 27 and the punching head 28 are driven to move by the first electric push rod 25. Under the action of the first electric push rod 25 and the second motor 27, multiple punching holes are performed on the arranged hardware, and punching holes at different positions of the hardware in the horizontal and vertical directions is never achieved;

[0060] During the punching process, the punching head 28 squeezes the slider 7 to both sides, and the slider 7 slides in the slide groove 72 to compress the second spring 71. The slider 7 can not only serve as a supporting force for the bottom of the hardware, but also the punching waste can easily fall from between the sliders 7. The waste punched by the hardware falls through the first lower hopper 4 and is then collected in the collection box 41 for easy recycling.

[0061] After the punching of the hardware is completed, the hardware waste falls through the first discharge port 12, and some debris splashes on the surface of the hardware. When the hardware is discharged, the cleaning brush cleans the debris on the surface of the hardware and drops it into the second discharge port 13; according to the different thicknesses of the hardware, when the hardware passes through the cleaning brush, the cleaning brush pushes up the lifting plate 51, and the lifting plate 51 slides on the sliding column 52. Under the action of the first spring 53, the lifting plate 51 is easy to quickly reset; the hardware debris falls into the second lower hopper 43 through the second lower hopper 43, flows to the drainage trough 42 through the second lower hopper 43, and flows into the collection box 41 through the drainage trough 42, so as to facilitate the unified collection of hardware waste.
