When the crankshaft rotates 180 degrees, the punching head descends to the lowest point. Subsequently, the crankshaft continues to rotate, and the punching head starts to move upward. As the crankshaft rotates, when the contact block contacts the elastic contact piece, the solenoid valve is turned on. Under the action of the second spring, drive the first piston to move upward, inject the air in the push cylinder into the through groove, and spray it onto the surface of the punching head through the spray holes to dissipate heat from the punching head.

[0015] A steel structure stamping equipment and its stamping method for wind power processing provided by the present invention have the following beneficial effects: 1. By setting up a stamping mechanism, the punching head can be driven to descend through the motor to punch the steel structure on the surface of the placement plate. At the same time, drive the drive plate to move downward synchronously to extrude the extrusion plate. The first clamping block moves towards the surface of the steel structure, and drives the second clamping block to move towards the surface of the steel structure synchronously through the first gear and the first toothed plate to perform lateral positioning on the steel structure. And drive the second piston to move downward synchronously, inject the air in the hollow part of the support rod into the push cylinder through the first one-way valve, push the first piston to drive the pressing block to move downward and tightly press on the surface of the steel structure to perform longitudinal positioning on the steel structure, ensuring the stability of the steel structure and improving the stamping efficiency.

[0016] 2. By setting up a heat dissipation mechanism, when the crankshaft rotates 180 degrees, the stamping head descends to the lowest point to punch the steel structure. Subsequently, as the crankshaft continues to rotate, the stamping head starts to move upward. As the crankshaft rotates, when the contact block contacts the elastic contact piece, the solenoid valve is turned on. Under the action of the second spring, the first piston is driven to move upward, injecting the air in the push tube into the through groove and spraying it out from the spray holes onto the surface of the stamping head to dissipate heat from the stamping head, reducing the working temperature of the stamping head, slowing down the process of material annealing and wear, and thus extending the service life of the stamping head.

[0017] 3. By setting up a blanking mechanism, the waste material falls into the blanking groove and impacts the baffle, driving the baffle to rotate clockwise and driving the second gear to rotate synchronously. Thereby, the second toothed plate is driven to move upward, driving the contact rod to move upward synchronously, and inserting the contact rod into the contact cylinder. Then the liquid extraction pump starts to work, spraying the heat dissipation liquid from the spray pipe onto the surface of the stamping head to dissipate heat from the stamping head.

The first gear 412 meshes with the two first toothed plates 411 for driving the first clamping blocks 409 and the second clamping blocks 410 to move relatively. Place the steel structure to be punched on the surface of the placement plate 3. By driving the crankshaft 401 to rotate through the motor 402, the stamping head 405 can be driven to descend through the connecting rod 403 and the driving rod 404 to punch holes in the steel structure on the surface of the placement plate 3. At the same time, the driving plate 406 is driven to move downward synchronously to extrude the extrusion plate 407. The first spring 408 contracts. The first clamping blocks 409 move towards the surface of the steel structure and drive the second clamping blocks 410 to move towards the surface of the steel structure synchronously through the first gear 412 and the first toothed plates 411 to perform lateral positioning on the steel structure.

[0024] Referring to Figures 1 - 6As shown, in a preferred embodiment, a support base 413 is fixedly installed at the bottom of the frame 2. Symmetrically fixed to the bottom of the support base 413 are support rods 414. Fixed to the bottom of the support rods 414 is a push cylinder 415.

Fixed to the bottom of the support rod 417 is a second piston 418. The support rod 414 is hollow. The second piston 418 is slidably installed in the hollow part of the support rod 414. A second spring 421 is installed in the inner cavity of the push cylinder 415. One end of the second spring 421 is fixedly connected to the push cylinder 415, and the other end of the second spring 421 is fixedly connected to the first piston 419, which is used to drive the first piston 419 to move upward.

A second one-way valve 424 is installed on the side wall of the support rod 414. The second one-way valve 424 conducts unidirectionally towards the inner cavity of the hollow part of the support rod 414 for air intake. When the stamping head 405 descends to punch holes in the steel structure, it drives the second piston 418 to move downward synchronously, injecting the air in the hollow part of the support rod 414 into the push cylinder 415 through the first one-way valve 423, pushing the first piston 419 to drive the pressing block 420 to move downward and tightly press on the surface of the steel structure, longitudinally positioning the steel structure, ensuring the stability of the steel structure, and improving the stamping efficiency.

[0025] In a preferred embodiment, during use, the steel structure to be punched is placed on the surface of the placement plate 3. The motor 402 can drive the crankshaft 401 to rotate, thereby driving the stamping head 405 to descend through the connecting rod 403 and the driving rod 404 to punch holes in the steel structure on the surface of the placement plate 3. At the same time, it drives the driving plate 406 to move downward synchronously, squeezing the extrusion plate 407. The first spring 408 contracts, and the first clamping block 409 moves towards the surface of the steel structure, and drives the second clamping block 410 to move towards the surface of the steel structure synchronously through the first gear 412 and the first toothed plate 411, laterally positioning the steel structure. Moreover, when the stamping head 405 descends to punch holes in the steel structure, it drives the second piston 418 to move downward synchronously, injecting the air in the hollow part of the support rod 414 into the push cylinder 415 through the first one-way valve 423, pushing the first piston 419 to drive the pressing block 420 to move downward and tightly press on the surface of the steel structure, longitudinally positioning the steel structure, ensuring the stability of the steel structure, and improving the stamping efficiency.

[0026] Refer to Figures 1 - 9As shown, in a preferred embodiment, a heat dissipation mechanism 5 is installed on the surface of the machine base 1 for dissipating heat from the stamping head 405, reducing the working temperature of the stamping head 405, slowing down the material annealing and wear processes, thereby extending the service life of the stamping head 405. The heat dissipation mechanism 5 includes a connecting block 501 and spray holes 503. The connecting block 501 is fixedly installed between two push cylinders 415. The connecting block 501 is arc-shaped. A through groove 502 is formed in the inner cavity of the connecting block 501, and spray holes 503 are formed in the side wall of the connecting block 501. The through groove 502 communicates with the inner cavity of the push cylinder 415, and a solenoid valve 504 is installed in the through groove 502 for controlling the conduction between the through groove 502 and the push cylinder 415. An annular groove 505 is formed in the inner cavity of the frame 2, and an elastic contact piece 506 is installed in the inner cavity of the annular groove 505. A contact block 507 is fixedly installed on the surface of the crankshaft 401 for controlling the conduction of the solenoid valve 504.

[0027] In a preferred embodiment, during use, the motor 402 drives the crankshaft 401 to rotate clockwise to drive the stamping head 405 to perform stamping. When the crankshaft 401 rotates 180 degrees, the stamping head 405 descends to the lowest point to punch the steel structure. Subsequently, the crankshaft 401 continues to rotate, and the stamping head 405 begins to move upward. As the crankshaft 401 rotates, when the contact block 507 contacts the elastic contact piece 506, the solenoid valve 504 is turned on. Under the action of the second spring 421, the first piston 419 is driven to move upward, injecting the air in the push cylinder 415 into the through groove 502 and spraying it onto the surface of the stamping head 405 through the spray holes 503 to dissipate heat from the stamping head 405, reducing the working temperature of the stamping head 405, slowing down the material annealing and wear processes, thereby extending the service life of the stamping head 405.

[0028] Refer to Figures 1 - 11 As shown, in a preferred embodiment, a blanking mechanism 6 is installed on the surface of the machine base 1 for blanking the punching waste. The blanking mechanism 6 includes a blanking groove 601 and a retaining piece 602. The blanking groove 601 is formed in the machine base 1 and the inner cavity of the placement plate 3. The retaining piece 602 is rotatably installed in the inner cavity of the blanking groove 601. A second gear 603 is fixedly installed on the side wall of the retaining piece 602. A second toothed plate 604 is slidably installed in the inner cavity of the machine base 1. The second toothed plate 604 meshes with the second gear 603. A third spring 605 is fixedly installed in the inner cavity of the machine base 1. One end of the third spring 605 is fixedly connected to the machine base 1, and the other end of the third spring 605 is fixedly connected to the second toothed plate 604 for driving the second toothed plate 604 to move downward. When the stamping head 405 punches the steel structure, the waste falls into the blanking groove 601 and impacts the retaining piece 602, driving the retaining piece 602 to rotate clockwise and driving the second gear 603 to rotate synchronously, thereby driving the second toothed plate 604 to move upward.

[0029] Refer to Figures 1 - 11As shown, in a preferred embodiment, a contact rod 606 is fixedly installed on the surface of the second toothed plate 604, and a contact cylinder 607 is fixedly installed in the inner cavity of the machine base 1 for controlling the operation of the liquid extraction pump 609. A solution cavity 608 is provided in the inner cavity of the machine base 1 for storing the heat dissipation liquid. A liquid extraction pump 609 is installed in the solution cavity 608. Nozzles 610 are symmetrically and fixedly installed on the inner wall of the blanking chute 601 for spraying the heat dissipation liquid onto the surface of the punching head 405. A water pipe is connected between the liquid outlet end of the liquid extraction pump 609 and the nozzles 610. When the second toothed plate 604 moves upward, it drives the contact rod 606 to move upward synchronously, causing the contact rod 606 to insert into the contact cylinder 607, then the liquid extraction pump 609 starts to work, spraying the heat dissipation liquid from the nozzles 610 onto the surface of the punching head 405 to dissipate heat from the punching head 405. Until the waste material falls off the surface of the baffle 602, the contact rod 606 disengages from the contact cylinder 607, and then the liquid extraction pump 609 stops working.

[0030] In a preferred solution, during use, when the punching head 405 punches a hole in the steel structure, the waste material falls into the blanking chute 601 and impacts the baffle 602, driving the baffle 602 to rotate clockwise and driving the second gear 603 to rotate synchronously, thereby driving the second toothed plate 604 to move upward, driving the contact rod 606 to move upward synchronously, causing the contact rod 606 to insert into the contact cylinder 607, then the liquid extraction pump 609 starts to work, spraying the heat dissipation liquid from the nozzles 610 onto the surface of the punching head 405 to dissipate heat from the punching head 405. Until the waste material falls off the surface of the baffle 602, the contact rod 606 disengages from the contact cylinder 607, and then the liquid extraction pump 609 stops working.

[0031] Specifically, the working principle of the steel structure punching equipment for wind power processing is as follows: During use, the steel structure to be punched is placed on the placement plate 3. The motor 402 can drive the crankshaft 401 to rotate, thereby driving the punching head 405 to descend through the connecting rod 403 and the driving rod 404 to punch holes in the steel structure on the surface of the placement plate 3. At the same time, it drives the driving plate 406 to move downward synchronously, squeezing the extrusion plate 407. The first spring 408 contracts, and the first clamping block 409 moves towards the surface of the steel structure, and drives the second clamping block 410 to move towards the surface of the steel structure synchronously through the first gear 412 and the first toothed plate 411 to perform lateral positioning on the steel structure. When the punching head 405 descends to punch a hole in the steel structure, it drives the second piston 418 to move downward synchronously, injecting the air in the hollow part of the support rod 414 into the push cylinder 415 through the first one-way valve 423, pushing the first piston 419 to drive the pressing block 420 to move downward and tightly press on the surface of the steel structure to perform longitudinal positioning on the steel structure, ensuring the stability of the steel structure and improving the punching efficiency.

[0032] When the stamping head 405 punches the steel structure, the waste material falls into the blanking chute 601 and impacts the baffle 602, driving the baffle 602 to rotate clockwise, driving the second gear 603 to rotate synchronously, thereby driving the second toothed plate 604 to move upward, driving the contact rod 606 to move upward synchronously, so that the contact rod 606 is inserted into the contact cylinder 607, then the liquid extraction pump 609 starts to work, spraying the heat dissipation liquid from the spray pipe 610 onto the surface of the stamping head 405 to dissipate heat from the stamping head 405. Until the waste material falls off the surface of the baffle 602, the contact rod 606 disengages from the contact cylinder 607, and then the liquid extraction pump 609 stops working.

[0033] The crankshaft 401 is driven by the motor 402 to rotate clockwise to drive the stamping head 405 to perform stamping. When the crankshaft 401 rotates 180 degrees, the stamping head 405 descends to the lowest point to punch the steel structure. Subsequently, the crankshaft 401 continues to rotate, and the stamping head 405 starts to move upward. As the crankshaft 401 rotates, when the contact block 507 contacts the elastic contact piece 506, the solenoid valve 504 is turned on. Under the action of the second spring 421, the first piston 419 is driven to move upward, injecting the air in the push cylinder 415 into the through groove 502 and spraying it onto the surface of the stamping head 405 through the spray holes 503 to dissipate heat from the stamping head 405, reducing the working temperature of the stamping head 405, slowing down the process of material annealing and wear, thereby prolonging the service life of the stamping head 405.

[0034] A stamping method for steel structures used in wind power processing, applicable to the above-mentioned stamping equipment for steel structures used in wind power processing, includes the following steps: S1: Stamping. Place the steel structure to be punched on the placement plate 3, drive the stamping head 405 to descend through the motor 402 to punch the steel structure on the surface of the placement plate 3. At the same time, drive the drive plate 406 to move downward synchronously to extrude the extrusion plate 407. The first clamping block 409 moves towards the surface of the steel structure, and drives the second clamping block 410 to move towards the surface of the steel structure synchronously through the first gear 412 and the first toothed plate 411 to perform lateral positioning on the steel structure, and drives the second piston 418 to move downward synchronously, injecting the air in the hollow part of the support rod 414 into the push cylinder 415 through the first one-way valve 423, pushing the first piston 419 to drive the pressing block 420 to move downward and tightly press on the surface of the steel structure to perform longitudinal positioning on the steel structure. S2: Blanking.

S3: Heat dissipation. The crankshaft 401 is driven by the motor 402 to rotate clockwise to drive the stamping head 405 to perform stamping. When the crankshaft 401 rotates 180 degrees, the stamping head 405 descends to the lowest point. Subsequently, the crankshaft 401 continues to rotate, and the stamping head 405 starts to move upward. As the crankshaft 401 rotates, when the contact block 507 contacts the elastic contact piece 506, the solenoid valve 504 is turned on. Under the action of the second spring 421, the first piston 419 is driven to move upward, injecting the air in the push tube 415 into the through groove 502 and spraying it onto the surface of the stamping head 405 through the spray hole 503 to dissipate heat from the stamping head 405.
