The lubricating fluid is pumped from the liquid storage cylinder to the spray cylinder between the two reciprocating plates through a vacuum pump and a pipeline. The electric cylinder B drives the baffle plate to move to the right, so that the spray holes on the baffle plate are communicated with the spray holes on the spray cylinder. As the vacuum pump continuously transports the lubricating fluid into the spray cylinder, the pressure in the spray cylinder between the two reciprocating plates increases, and the lubricating fluid is sprayed on the position of the steel strip where punching is about to be performed through the spray holes, reducing the friction between the upper die base and the steel strip and reducing the surface wear of the steel strip.

[0020] 2. Process the burrs generated at the punching position of the steel strip to prevent the burrs from having an adverse impact on the staff.

The second spring pushes the cleaning plate to move outwards, so that the cleaning plate contacts the edge of the punching position. The rotating motor drives the cleaning plate to rotate through the rotating plate, and the cleaning plate cleans the burrs at the punching position, realizing the cleaning of the steel strip surface for the subsequent processing of the steel strip.

[0021] 3. The punching process can be carried out at different positions of the steel strip to meet different usage occasions. According to the punching position data stored internally, the control system drives the sliding plate to move through the electric cylinder C, the sliding plate drives the hydraulic cylinder to move, and the hydraulic cylinder drives the upper die base to move, so that the upper die base is located directly above the punching position of the steel strip; at the same time, the control system drives the lower die base to move through the electric cylinder D, so that the lower die base is located directly below the punching position of the steel strip.

[0040] Both groups of conveying units are composed of two groups of conveying wheels 19. The two groups of conveying wheels 19 are both installed on the frame 11. The two groups of conveying wheels 19 are of the structure of electric rollers inside. Grooves are provided on the circumferences of the two groups of conveying wheels 19. The two groups of conveying wheels 19 are located on both sides of the frame 11. Encoders and displacement sensors are installed inside the conveying wheels 19; The position data of the punching of the steel strip 17 is stored in the control system. The punching diameter of the steel strip 17 is The distance that the reciprocating plate 121 on the left is driven by the electric cylinder A122 on the left to move is The distance that the reciprocating plate 121 on the right is driven by the electric cylinder A122 on the right to move is The length of the spray cylinder 12 is ; The range where the spray cylinder 12 sprays the lubricating liquid through the spray holes forms a rectangle. The width distance of the rectangle is The length distance of the rectangle is The spraying range of the lubricating liquid or the area of the rectangle is , and ;

[0041] The control system calculates the width distance of the rectangle according to the calculation formula. The calculation formula is as follows:

[0042] ;

[0043] The encoder inside the conveying wheel 19 monitors the moving speed of the steel strip 17 and uploads it to the control system. The time for the spray cylinder 12 to spray the lubricating liquid at the punching position. The control system calculates the length distance of the rectangle according to the moving speed of the steel strip 17 and the time , the calculation formula is as follows:

[0044] ;

[0045] The control system calculates the spraying range of the lubricating fluid or the area of the rectangle according to the calculation formula , and substitutes and into it. The calculation formula is as follows:

[0046] ;

[0047] ;

[0048] The control system adjusts the spraying time of the lubricating fluid , the distance that the left electric cylinder A122 drives the left reciprocating plate 121 to move and the distance that the right electric cylinder A122 drives the right reciprocating plate 121 to move , to realize the adjustment of the spraying area of the lubricating fluid .

[0049] Working principle: Press the start button on the control panel 1, and the device starts. The staff puts the steel belt 17 from the feeding port 111 into the position between the two groups of conveying wheels 19 on the left. The steel belt 17 is located in the grooves of the two groups of conveying wheels 19, and the two groups of conveying wheels 19 drive the steel belt 17 to move to the right;

[0050] During the process of the steel belt 17 moving to the right, the control system adjusts the extended distances of the two side electric cylinders A122 respectively according to the data of the punching positions of the steel belt 17 stored inside, so that the position between the two side reciprocating plates 121 is exactly opposite to the position where the steel belt 17 is about to be punched;

[0051] If the punching position of the steel belt 17 is on the left, the distance that the left electric cylinder A122 drives the left reciprocating plate 121 to move is less than the distance that the right electric cylinder A122 drives the right reciprocating plate 121 to move; if the punching position of the steel belt 17 is on the right, the distance that the right electric cylinder A122 drives the right reciprocating plate 121 to move is less than the distance that the left electric cylinder A122 drives the left reciprocating plate 121 to move.

[0052] When the position between the two reciprocating plates 121 is directly opposite to the position where the steel strip 17 is about to be punched, the two electric cylinders A 122 feedback data to the control system. The control system opens the solenoid valve in the connecting pipe of the spray cylinder 12 between the two groups of reciprocating plates 121, and extracts the lubricating liquid from the liquid storage cylinder 13 into the spray cylinder 12 between the two groups of reciprocating plates 121 through a vacuum pump (not shown in the figure) and the pipe. The electric cylinder B 124 drives the baffle plate 123 to move to the right, so that the spraying holes on the baffle plate 123 are communicated with the spraying holes on the spray cylinder 12. As the vacuum pump continuously transports the lubricating liquid into the spray cylinder 12, the pressure in the spray cylinder 12 between the two reciprocating plates 121 increases, and the lubricating liquid is sprayed on the position of the steel strip 17 where punching is about to be performed through the spraying holes.

[0053] After the lubricating liquid is sprayed on the steel strip 17, the flow sensor in the spray cylinder 12 feedbacks data to the control system. The control system controls the conveying wheel 19 to continue driving the steel strip 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 strip 17 needs to be punched is directly opposite to the upper die base 14 and the lower die base 15. The encoder inside the conveying wheel 19 feedbacks data to the control system. The control system controls the hydraulic cylinder 143 to drive the upper die base 14 to move downward, and the upper die base 14 and the lower die base 15 cooperate to punch the steel strip 17. The waste generated after punching falls into the lower die base 15 and is discharged from the blanking chute.

[0054] 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. The hydraulic cylinder 143 feedbacks 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 to the right through the conveying wheel 19, so that the position where the steel strip 17 is punched is directly above the detection cylinder 16.

[0055] When the position where the steel strip 17 is punched is directly above the detection cylinder 16, the conveying wheel 19 feedbacks the displacement data of the steel strip 17 to the control system. 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 strip 17. Then, the control system energizes the first springs 165 on both sides. Each turn of the first spring 165 generates a magnetic field that attracts each other, and this magnetic field causes the first spring 165 to contract. The left first spring 165 pulls the left contact ring 164 to move to the left, and the left contact ring 164 drives the left detection plate 162 to move to the left. The right first spring 165 pulls the right contact ring 164 to move to the right, and the right contact ring 164 drives the right detection plate 162 to move to the right, so that both detection plates 162 are in contact with the edge of the punching position.

[0056] When the detection plates 162 on both sides come into contact with the edges of the punching positions, the pressure sensors in the detection plates 162 on both sides feed the data back to the control system. 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 number of turns of the coil 161, and then flows out from the metal plate on the right to the control system. The control system detects this current and calculates the diameter data of the punching position through calculation. The effective number of turns of the coil 161 refers to the number of turns between the metal plates on both sides;

[0057] When the obtained diameter data is less than the set data, which is set in advance by the staff and indicates that burrs have occurred at the punching position and need to be cleaned, the conveying wheel 19 drives the steel belt 17 to continue moving to the right, so that the punching position of the steel belt 17 is directly above the cleaning cylinder 18. The conveying wheel 19 feeds the displacement data of the steel belt 17 back to the control system. 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 less than the radius of the punching. Then, the control system controls the lifting electric cylinder 181 to drive the lifting plate 182 to move upward. The lifting plate 182 drives the rotating motor 184 and the rotating plate 185 to move upward. The rotating plate 185 drives the upper end of the cleaning plate 186 to be higher than the upper side of the steel belt 17. Then, the control system cuts off the power supply of the second spring 183. The second spring 183 gradually elongates under its own elastic force. The second spring 183 pushes the cleaning plate 186 to move outward, so that the cleaning plate 186 comes into contact with the edge of the punching position. The rotating motor 184 drives the cleaning plate 186 to rotate through the rotating plate 185. The abrasive particles on the cleaning plate 186 clean the burrs at the punching position while rotating at the punching position, realizing the cleaning of the surface of the steel belt 17 for the subsequent processing of the steel belt 17;

[0058] After the rotating motor 184 drives the cleaning plate 186 to rotate to the set number of turns, which is set by the staff, the control system energizes the second spring 183. The second spring 183 pulls 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 less than the radius of the punching. Then, the lifting electric 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. The control system cuts off the power supply of the second spring 183. The second spring 183 pushes the cleaning plate 186 to move outward under its own elastic force. The two groups 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.

[0059] When the diameter data obtained by the control system is equal to the set data, it means that there are no burrs 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.

[0060] When the diameter data obtained by the control system is greater than the set data, it indicates that the size of the upper die holder 14 is incorrect and the upper die holder 14 needs to be replaced. The conveying wheel 19 drives the steel belt 17 to move leftward and discharge from the feed port 111. The staff removes the upper die holder 14 on the hydraulic cylinder 143 and installs the correct upper die holder 14.
