[0045] The classification plate 4 is a disc plate, and the output shaft of the classification motor 41 is connected to the middle of the classification plate 4. The classification motor 41 is installed on the table 111. Two groups of classification rods 42 are arranged on the classification plate 4. The two groups of classification rods 42 are perpendicular to each other. A number of detection plates 43 are slidably installed on one side of the classification rod 42, and a coil 44 is arranged on the other side of the classification rod 42; the several detection plates 43 are connected to the classification rod 42 through springs, one side of the detection plate 43 is made of nylon, and a metal block is arranged on the other side of the detection plate 43, the metal block is in contact with the coil 44, and the metal block and the coil 44 are electrically connected to the control system, the angular bisectors of the two groups of classification rods 42 are opposite to the outlet of the conveyor belt 151, and the transplanting robot is located at the inlet of the conveyor belt 151.

[0046] Working principle: Place the plate 12 in the loading slot and position the plate 12 with the loading slot. At this time, the position where the plate 12 needs to be punched contacts the positive electrode ring 201. Then, press the start button on the control panel 1 to start the punch press. The control system draws the air in the adsorption chamber outward through the negative pressure system, so that the adsorption port 221 adsorbs and positions the plate 12. After the plate 12 is adsorbed and positioned, the negative pressure system feeds back the pressure signal to the control system. The control system drives the screw rod 211 to rotate through the driving motor 212. The screw rod 211 rotates and drives the loading plate 21 to move to the left. The loading plate 21 drives the lower die base 2, the adsorption plate 22, the plate 12 and the pressure plate 23 to move to the left, so that the lower die base 2 and the plate 12 are located below the upper die base 3.

[0047] When the lower die base 2 and the plate 12 are located below the upper die base 3, the encoder in the drive motor 212 feeds back data to the control system. The control system drives the upper die base 3 to move downward through the servo electric cylinder 34, and the positive electrode ring 201 and the negative electrode ring 323 are respectively connected to the positive and negative electrodes of the power supply. The upper die base 3 drives the punch 31 and the reciprocating cylinder 32 to move downward, so that the negative electrode ring 323 on the lower side of the reciprocating cylinder 32 contacts the position of the plate 12 where a hole needs to be punched. At this time, current will flow through the plate 12 between the negative electrode ring 323 and the positive electrode ring 201. The current causes the position of the plate 12 where a hole needs to be punched to heat up and produce plastic deformation, thereby reducing the stress during the stamping process.

[0048] When the negative electrode ring 323 and the positive electrode ring 201 heat the punching position of the plate 12 to the set time, the control system cuts off the power to the negative electrode ring 323 and the positive electrode ring 201 and energizes the two ends of the telescopic spring 331. After the two ends of the telescopic spring 331 are energized, each turn of the telescopic spring 331 generates a mutually attractive magnetic field, which causes the telescopic spring 331 to shrink as a whole, and the telescopic spring 331 pulls the follower plate 321 to move upward. Since the horizontal axis 322 in the reciprocating cylinder 32 is inserted into the spiral groove, the reciprocating cylinder 32 rotates while the follower plate 321 pulls the reciprocating cylinder 32 to move upward, and the reciprocating cylinder 32 drives the negative electrode ring 323 to move upward without contacting the plate 12. At this time, the lower end of the punch 31 emerges from the reciprocating cylinder 32.

[0049] When the lower end of the punch 31 emerges from the reciprocating cylinder 32, the displacement sensor feeds back the displacement data of the reciprocating cylinder 32 to the control system, and the control system controls the servo electric cylinder 34 to drive the upper die base 3 to continue to move downward, and the upper die base 3 drives the punch 31 to move downward, and the punch 31 punches the plate 12. The punch 31 drives the punched circular waste to continue to move downward, and the circular waste drives the pressure plate 23 to move downward. The pressure plate 23 compresses the spring at the same time, and a pressurized chamber is formed between the lower side of the pressure plate 23 and the lower die base 2. As the pressure plate 23 continues to move downward, the air pressure in the pressurized chamber gradually increases, and the one-way valve in the pipeline between the air bag 142 and the lower die base 2 is pushed open by the pressurized air, and the pressurized air is transported to the air bag 142 through the pipeline for storage.

[0050] When the servo electric cylinder 34 drives the punch 31 to move to the lowermost side through the upper die base 3, the displacement sensor in the servo electric cylinder 34 feeds back the displacement data of the punch 31 to the control system, and the control system drives the upper die base 3 to move upward through the servo electric cylinder 34, and the upper die base 3 drives the punch 31 to move upward. At this time, the spring between the pressure plate 23 and the lower die base 2 is released, and the spring pushes the pressure plate 23 and the round waste to move upward. At this time, the volume of the pressurized chamber becomes larger, and the air pressure in the pressurized chamber decreases. The one-way valve in the pipeline between the lower die base 2 and the air bag 142 is closed, and the one-way valve in the pipeline connecting the lower die base 2 and the external air is opened, and the external air enters the pressurized chamber to realize the extraction of external air, so that the extracted air can be transported to the air bag 142 for storage again.

[0051] When the servo electric cylinder 34 drives the punch 31 to move to the uppermost side through the upper die seat 3, the displacement sensor in the servo electric cylinder 34 feeds back the displacement data of the punch 31 to the control system, and the control system takes out the circular waste material through the transplanting manipulator and places it on the conveyor belt 151. After the circular waste material is placed on the conveyor belt 151, the transplanting manipulator feeds back the position data of the circular waste material to the control system, and the control system controls the driving motor 212 to drive the screw rod 211 to reverse, and the screw rod 211 reverses and drives the carrier plate 21 to move to the far right. The control system cooperates with the negative pressure system and the adsorption port 221 to not adsorb the stamped sheet 12, and the staff takes down the stamped sheet 12;

[0052] When the punch 31 is located at the uppermost side, the control system opens the solenoid valve in the pipe between the air bag 142 and the air blowing port, connects the two semiconductors on the refrigeration plate 141 to the circuit, and cooperates with the dust removal box 13 and the negative pressure system. The metal plate and the two semiconductors on the refrigeration plate 141 are the refrigeration ends of the Peltier effect, and the air in the air bag 142 is cooled by the refrigeration end. The cooled air is sprayed onto the punch 31 from the air blowing port through the pipe. While the cooled air cools the punch 31, the debris or impurities on the punch are blown off. The negative pressure system and the dust removal box 13 cooperate to adsorb the impurities and debris on the filter net, and the air is discharged to the outside air through the negative pressure system, so as to realize the dust removal of the punch press and prevent impurities from having an adverse effect on the punching.

[0053] When the round waste is placed on the conveyor belt 151 by the transplanting robot, the control system drives the conveyor belt 151 to move through the roller 15, and the conveyor belt 151 drives the round waste to move forward. At this time, the forward direction of the round waste is in a coincidence with the angular bisector of the two groups of classification rods 42. The two sides of the round waste respectively push the detection plates 43 on the two groups of classification rods 42 to move, and the detection plates 43 on both sides compress the springs respectively. The metal block on the detection plate 43 contacts the coil 44. At this time, the encoder inside the roller 15 feeds back the position data of the round waste to the control system, and the control system connects one end of the coil 44 and the metal block to the circuit. The current enters from the metal block, flows through the effective number of turns of the coil 44, and then flows out from one end of the coil 44 to the control system. The control system detects the current and obtains the diameter of the round waste after calculation and processing. The effective number of turns refers to the number of turns from the metal block to one end of the coil 44.

[0054] After the control system obtains the diameter of the circular waste, it further calculates the area of ​​the circular waste; when the calculated waste area is larger than the set area, the sorting motor 41 drives the sorting plate 4 to rotate forward, and the sorting plate 4 drives the two groups of sorting rods 42 to rotate forward, and the two groups of sorting rods 42 drive the circular waste to fall from one side of the conveyor belt 151 to the waste box A45; when the calculated waste area is smaller than the set area, the sorting motor 41 drives the sorting plate 4 to reverse, and the sorting plate 4 drives the two groups of sorting rods 42 to reverse, and the two groups of sorting rods 42 drive the circular waste to fall from the other side of the conveyor belt 151 to the waste box B451, thereby realizing the classified collection of waste.

[0055] After the stamping is completed, the control system first cuts off the power of the telescopic spring 331, connects the two semiconductors on the cooling plate 326 to the circuit and energizes the electromagnet 311. The metal plate and the two semiconductors on the cooling plate 326 are the cooling end of the Peltier effect, and the lubricating fluid is cooled by the cooling end. After the telescopic spring 331 is cut off, it gradually lengthens under the action of its own elastic force. The telescopic spring 331 pushes the follower plate 321 to move downward. Since the horizontal shaft 322 in the reciprocating cylinder 32 is inserted into the spiral groove, the follower plate 321 pushes the reciprocating cylinder 32 downward. While moving, the reciprocating cylinder 32 reverses, and then the electromagnet 311 in the punch 31 faces the magnetic material on the push plate 325. The magnetic field of the electromagnet 311 and the magnetic field of the magnetic material attract each other. Under the action of the attraction, the push plate 325 moves to the side close to the electromagnet 311 and stretches the reset spring. During the movement, the push plate 325 squeezes the cooled lubricating liquid to contact the sponge 324, so that the cooled lubricating liquid enters the sponge 324, so that the punch 31 is lubricated by the lubricating liquid.

[0056] The electromagnet 311 is energized for a set time and then cuts off, pushing the plate 325 back to its original position under the action of the reset spring, after which the control system energizes the telescopic spring 331, and each turn of the telescopic spring 331 generates a mutually attractive magnetic field, which compresses the telescopic spring 331, shortening the telescopic spring 331 as a whole, and the telescopic spring 331 pulls the reciprocating cylinder 32 to move upward by following the plate 321, while the reciprocating cylinder 32 rotates forward, and the reciprocating cylinder 32 drives the sponge 324 to move upward while rotating, and the cooled lubricating liquid is applied to the punch 31 through the sponge 324, and the lubricating liquid cools the punch 31 while lubricating it, thereby reducing the friction between the punch 31 and the plate 12, preventing the punch 31 from being excessively worn, and extending the service life of the punch 31.
