[0040] In use, the plate to be punched is placed on the top of the lower die 6 below the upper die 4, and then the two servo motors 805 are started to rotate the two lead screws 806, thereby moving the L-shaped sliding block 804 and the oil collecting box 8 away from the servo motor 805 along the lead screw 806, moving the brush 803 on one side of the oil collecting box 8 from one side of the workpiece to the other side, thereby sweeping the impurities on the surface of the workpiece, then moving the oil collecting box 8 to the surface of the workpiece, then starting the electric telescopic rod 201 to move the pressing plate 202 downward, pushing the positioning block 303 to press the spring 304, causing the spring 304 to elastically deform, and moving the connecting rod 305, the mounting plate 306 and the upper die 4 downward, causing the bottom of the upper die 4 to approach the oil collecting box 8, then stopping the extension of the electric telescopic rod 201, and starting the oil pump 701 to extract the lubricating oil in the oil tank 7, causing the lubricating oil to pass through the oil extraction pipe 702 and the oil outlet hose 703, enter the inside of the oil collecting box 8, and be sprayed from the multiple spray heads a801 and the multiple spray heads b802 onto the upper die 4 and the lower die 6 respectively, then reversing the servo motor 805 to reset the oil collecting box 8 and the brush 803, and continuing to control the electric telescopic rod 201 to move the upper die 4 downward until the upper die 4 punches the workpiece.

[0041] The working principle is as follows:

[0042] In use, the plate to be punched is placed on the top of the lower die 6 below the upper die 4, and then the two servo motors 805 are started to rotate the two lead screws 806, thereby moving the L-shaped sliding block 804 and the oil collecting box 8 away from the servo motor 805 along the lead screw 806, moving the brush 803 on one side of the oil collecting box 8 from one side of the workpiece to the other side, thereby sweeping the impurities on the surface of the workpiece, then moving the oil collecting box 8 to the surface of the workpiece, then starting the electric telescopic rod 201 to move the pressing plate 202 downward, pushing the positioning block 303 to press the spring 304, causing the spring 304 to elastically deform, and moving the connecting rod 305, the mounting plate 306 and the upper die 4 downward, causing the bottom of the upper die 4 to approach the oil collecting box 8, then stopping the extension of the electric telescopic rod 201, and starting the oil pump 701 to extract the lubricating oil in the oil tank 7, causing the lubricating oil to pass through the oil extraction pipe 702 and the oil outlet hose 703, enter the inside of the oil collecting box 8, and be sprayed from the multiple spray heads a801 and the multiple spray heads b802 onto the upper die 4 and the lower die 6 respectively, then reversing the servo motor 805 to reset the oil collecting box 8 and the brush 803, and continuing to control the electric telescopic rod 201 to move the upper die 4 downward until the upper die 4 punches the workpiece.

[0043] After the stamping of the workpiece is completed, the electric telescopic rod 201 is controlled to retract, so that the bottom of the pressing plate 202 is separated from the top of the positioning block 303. At this time, the spring 304 which is elastically deformed exerts a reverse force on the positioning block 303, so that the positioning block 303 drives the mounting plate 306 to reset together with the upper die 4, thereby separating the upper die 4 from the surface of the workpiece.

[0044] In addition, through the arrangement of the counterweight 704, when the oil collecting box 8 pulls the oil outlet hose 703 to move, the oil outlet hose 703 is pulled at one end, so that the oil outlet hose 703 is always kept in a taut state, and the problem of the oil outlet hose 703 being stuck at the bottom of the oil collecting box 8 is reduced.

[0045] Further, when the upper die 4 and the lower die 6 need to be replaced, the threaded screw rod a310 is rotated by the servo motor a309, the die changing block 3 is driven to move away from the servo motor a309, the upper die 4 is moved, until the positioning block 303 above the other upper die 4 moves below the position sensor b203. At this time, the position sensor b203 detects the positioning block 303 above the other upper die 4, generates an electric signal, and transmits it to the control terminal. The control terminal is closed to complete the replacement of the upper die 4. After the replacement of the upper die 4 is completed, the threaded screw rod b505 is rotated by the servo motor b504, the two sliding blocks 5 are driven to move away from the servo motor b504, so that the lower die 6 is moved, until the other lower die 6 moves below the upper die 4. At this time, the position sensor a102 inside the limiting sliding groove 101 detects the protrusion 501, generates an electric signal, and transmits it to the control terminal. The control terminal is closed to complete the replacement of the lower die 6.

[0046] If the upper die 4 installed at the bottom of the mounting plate 306 needs to be replaced, the fixed bolts 402 on both sides of the pressing cavity 301 are unscrewed, the upper die 4 is disassembled, and then the replaced upper die 4 is fixed on the mounting plate 306 by the fixed bolts 402. Similarly, when the lower die 6 installed between the two sliding blocks 5 needs to be replaced, the positioning bolts 506 on one side of the two sliding blocks 5 are unscrewed, the lower die 6 is pulled out along the limiting groove 503, and the replaced lower die 6 is fixed between the two sliding blocks 5 by the positioning bolts 506.

[0047] In addition, the control panel is arranged on one side of the base 1. The control panel can control the on-off of the electric telescopic rod 201, the position sensor a102, the position sensor b203, the servo motor a309, the servo motor b504, the oil pump 701 and the servo motor 805.
