[0027] The two conveying units are composed of two conveying wheels 19, which are installed on the frame 11. The two conveying wheels 19 are internally electric roller structures.

[0028] Working principle: Press the start button on the control panel 1, the device starts, and the staff puts the steel belt 17 from the feed port 111 into the position between the two sets of conveying wheels 19 on the left. The steel belt 17 is located in the grooves of the two sets of conveying wheels 19, and the two sets of conveying wheels 19 drive the steel belt 17 to move to the right; When the steel belt 17 moves to the right, the control system adjusts the extension distance of the electric cylinder A122 on both sides according to the punching position data of the steel belt 17 stored internally, so that the position between the reciprocating plates 121 on both sides is exactly at the position where the steel belt 17 is about to be punched; If the punching position of the steel strip 17 is on the left side, the distance that the left electric cylinder A122 drives the left reciprocating plate 121 to move is smaller than the distance that the right electric cylinder A122 drives the right reciprocating plate 121 to move; if the punching position of the steel strip 17 is on the right side, the distance that the right electric cylinder A122 drives the right reciprocating plate 121 to move is smaller than the distance that the left electric cylinder A122 drives the left reciprocating plate 121 to move.

[0029] When the position between the two side reciprocating plates 121 is exactly opposite to the position where the steel strip 17 is about to be punched, the electric cylinders A122 on both sides feed back data to the control system, and the control system opens the solenoid valve in the connecting pipe of the spray barrel 12 between the two sets of reciprocating plates 121, and draws the lubricating liquid from the liquid storage cylinder 13 to the spray barrel 12 between the two sets of reciprocating plates 121 through the vacuum pump (not shown in the figure) and the pipeline, and the electric cylinder B124 drives the baffle plate 123 to move to the right, so that the spray hole on the baffle plate 123 is connected with the spray hole on the spray barrel 12, and as the vacuum pump continues to transport the lubricating liquid to the spray barrel 12, the pressure of the spray barrel 12 between the two side reciprocating plates 121 increases, and the lubricating liquid is sprayed through the spray hole on the position of the steel strip 17 that is about to be punched.

[0030] After the lubricating liquid is sprayed on the steel belt 17, the flow sensor in the spray barrel 12 feeds back data to the control system, and the control system controls the conveying wheel 19 to continue to drive the steel belt 17 to move to the right to the position between the upper die base 14 and the lower die base 15, so that the position where the steel belt 17 needs to be punched is opposite to the upper die base 14 and the lower die base 15, and the encoder inside the conveying wheel 19 feeds back data to the control system, and the control system controls the hydraulic cylinder 143 to drive the upper die base 14 to move downward, and the upper die base 14 cooperates with the lower die base 15 to punch the steel belt 17, and the waste generated after punching falls into the lower die base 15 and is discharged from the discharge chute.

[0031] After the upper die base 14 and the lower die base 15 cooperate to punch the steel strip 17, the hydraulic cylinder 143 drives the upper die base 14 to move upward, and the hydraulic cylinder 143 feeds back the displacement data of the upper die base 14 to the control system. The control system continues to drive the steel strip 17 to move rightward through the conveying wheel 19, so that the punched position of the steel strip 17 is located directly above the detection cylinder 16.

[0032] When the punched position of the steel belt 17 is located directly above the detection cylinder 16, the conveying wheel 19 feeds back the displacement data of the steel belt 17 to the control system, and the control system drives the detection cylinder 16 to move upward through the lifting electric cylinder 163, so that the upper end of the detection plate 162 is flush with the steel belt 17. After that, the control system energizes the first springs 165 on both sides, and each turn of the first spring 165 generates a mutually attractive magnetic field, which causes the first spring 165 to contract, and the first spring 165 on the left side pulls the contact ring 164 on the left side to move left, and the contact ring 164 on the left side drives the detection plate 162 on the left side to move left, and the first spring 165 on the right side pulls the contact ring 164 on the right side to move right, and the contact ring 164 on the right side drives the detection plate 162 on the right side to move right, so that the detection plates 162 on both sides are in contact with the edge of the punching position.

[0033] When the detection plates 162 on both sides contact the edge of the punching position, the pressure sensors in the detection plates 162 on both sides feed back data to the control system, and the control system connects the metal plates in the contact rings 164 on both sides to the circuit. The current enters from the metal plate on the left, flows through the effective turns of the coil 161, and then flows out from the metal plate on the right to the control system. The control system detects the current and obtains the diameter data of the punching position through calculation. The effective turns of the coil 161 refers to the turns between the metal plates on both sides. When the obtained diameter data is smaller than the set data, which is set in advance by the staff, it indicates that burrs are generated at the punching position and need to be cleaned. The conveying wheel 19 drives the steel belt 17 to continue to move to the right, so that the punching position of the steel belt 17 is located directly above the cleaning cylinder 18. The conveying wheel 19 feeds back the displacement data of the steel belt 17 to the control system, and the control system controls the second spring 183 to be energized, and the second spring 183 drives the cleaning plate 186 to move inward, so that the distance from the cleaning plate 186 to the center of the rotating plate 185 is smaller than the radius of the punching hole. After that, the control system controls the lifting electric cylinder 181 to drive the lifting plate 182 to move upward, and the lifting plate 182 drives The rotating motor 184 and the rotating plate 185 move upward, and the rotating plate 185 drives the upper end of the cleaning plate 186 to be higher than the upper side of the steel strip 17. Then, the control system cuts off the power of the second spring 183, and the second spring 183 gradually becomes longer under the action of its own elastic force. The second spring 183 pushes the cleaning plate 186 to move outward, so that the cleaning plate 186 contacts the edge of the punching position. The rotating motor 184 drives the cleaning plate 186 to rotate through the rotating plate 185. The grinding particles on the cleaning plate 186 clean the burrs at the punching position while rotating at the punching position, thereby cleaning the surface of the steel strip 17 to facilitate the subsequent processing of the steel strip 17. After the rotating motor 184 drives the cleaning plate 186 to rotate to the set number of circles, the set number of circles is set by the staff, and the control system energizes the second spring 183, and the second spring 183 pulls the cleaning plate 186 inward, so that the distance from the cleaning plate 186 to the center of the rotating plate 185 is less than the radius of the punching hole, and then the lifting cylinder 181 drives the lifting plate 182, the second spring 183, the rotating motor 184, the rotating plate 185 and the cleaning plate 186 to move downward, so that the upper end of the cleaning plate 186 is lower than the lower side of the steel belt 17, and the control system cuts off the power to the second spring 183, and the second spring 183 pushes the cleaning plate 186 outward under the action of its own elastic force, and the two sets of conveying wheels 19 on the right continue to drive the steel belt 17 to move to the right, so that the cleaned steel belt 17 is discharged from the discharge port 112.

[0034] When the diameter data obtained by the control system is equal to the set data, it means that there is no burr at the punching position and no cleaning is required. The conveying wheel 19 drives the steel belt 17 to move to the right and is discharged from the discharge port 112.

[0035] When the diameter data obtained by the control system is greater than the set data, it means that the size of the upper die seat 14 is incorrect and the upper die seat 14 needs to be replaced. The conveying wheel 19 drives the steel belt 17 to move to the left and is discharged from the feed port 111. The staff removes the upper die seat 14 on the hydraulic cylinder 143 and installs the correct upper die seat 14.
