Description

Technical Field

[0001] The invention relates to the technical field of punching equipment, and in particular to a punching device for processing a chemical container support plate. Background Art

[0002] In the field of nuclear power generation, nuclear reactor rods are one of the core components, and their performance directly affects the safety and efficiency of nuclear reactors. In order to ensure the reliability of nuclear reactor rods under extreme conditions, they need to be rigorously tested and simulated. As a test platform, the electrothermal simulation container has a complex internal structure and requires extremely high processing accuracy for the support plate. Traditional drilling methods have problems such as excessive drill bit obstruction, overheating of drilling, poor flatness of the drilling edge, and poor drilling accuracy when the feed rate is too fast. If the feed rate is too small, it will increase the time consumption of drilling and reduce the drilling efficiency.

[0003] In summary, the traditional punching device is difficult to meet the high-precision and high-efficiency production requirements of the support plate for the nuclear reactor rod electrothermal simulation container; therefore, we propose a punching device for chemical container support plate processing to solve this problem.

[0027] The beneficial effects of the present invention are:

[0028] 1. In the present invention, a punching device for processing a support plate of a chemical container is described. The plate to be punched is placed on two support platforms, and then two knobs are manually rotated to drive two screws to rotate. The screws cooperate with the threads of the driving plate and drive two clamping plates to approach each other under the guidance of the guide plate, so that the two clamping plates abut against the two sides of the plate, and the plate is clamped and fixed. The first screw is driven to rotate by starting a first rotating motor. The first screw drives the moving frame to move forward and backward by cooperating with the threads of the square plate. The moving frame drives the moving platform and the support platform to move forward and backward, thereby adjusting the front and rear position of the plate. The second screw is driven to rotate by starting a second rotating motor. The second screw drives the moving platform to move left and right by cooperating with the threads of the slide plate, thereby adjusting the left and right position of the plate, so that the drill bit is located directly above the position to be drilled. Then, the driving motor and the first electric push rod are started. The driving motor drives the driving gear to rotate. The driving gear drives the connecting shaft and the drill bit to rotate by meshing with the driven gear. The first electric push rod drives the lifting plate to move downward, so that the high-speed rotating drill bit moves downward to achieve drilling of the plate.

[0029] 2. In the present invention, the punching device for processing the support plate of a chemical container starts a water pump and a refrigerator. The water pump provides the power of water fluid so that the water in the water supply pipe is cooled by the refrigerator and then introduced into the connecting head, and then introduced into the cavity of the drill bit through the cooling flow channel in the connecting shaft, and then guided out from multiple spiral guide ports to spray toward the reaming cutter, so as to realize the cooling of the connecting shaft, the drill bit and the reaming cutter;

[0030] 3. In the present invention, the punching device for processing the support plate of a chemical container monitors the resistance of the lifting plate moving downward through a pressure sensor, that is, the drilling resistance of the drill is monitored. When the pressure sensor detects that the pressure increases, the controller controls the working speed of the first electric push rod to decrease and controls the water pump to increase the power, thereby slowing down the speed of the drill moving downward to slow down its heating speed, and increasing the speed of the water pump to deliver water to improve the cooling effect on the drill. During the drilling process, the temperature of the plate is monitored through a temperature sensor. When the temperature sensor detects that the temperature increases, the controller controls the refrigerator to increase the power, thereby improving the cooling effect;

[0031] 4. In the present invention, the punching device for processing the support plate of a chemical container controls the first electric push rod to control the lifting plate to continue to move downward after the drill bit completes drilling, until the upper scraping edge of the reaming knife contacts the plate to scrape off the burrs on the top of the plate. At this time, the controller controls the two second electric push rods to start, and the two second electric push rods drive the two horizontal plates to move downward synchronously. The horizontal plate drives the arc frame to move downward through the vertical rod, and the arc frame drives the annular guide rail and the disc to rotate and move downward at the same time. The disc drives multiple guide frames and multiple reaming knives to move horizontally to the side away from the connecting shaft through sliding cooperation with the inclined rod, so that the reaming edge contacts the inner wall of the drilled hole of the plate to realize the reaming work. At the same time, the burrs on the bottom of the plate are scraped off by the lower scraping edge, and the chamfering of the drilled hole of the plate is realized by the upper chamfering edge and the lower chamfering edge.

[0032] 5. In the present invention, the punching device for processing a chemical container support plate, as the hole expansion work proceeds, the horizontal plate gradually approaches the lifting plate, so that the first conductive tube and the second conductive tube approach the lifting plate, so that the resistance of the first resistor bar connected to the drive motor decreases, and the speed of the drive motor increases. At the same time, the resistance of the second resistor bar connected to the second electric push rod increases, and the contraction speed of the output end of the second electric push rod slows down, thereby reducing the speed of the horizontal plate moving downward, so that the speed of the hole expansion knife moving outward slows down, so as to reduce the feed amount of the hole expansion knife per unit time, thereby achieving a more refined hole expansion, chamfering and deburring effect, thereby ensuring the flatness of the hole opening surface of the plate;

[0033] 6. In the present invention, the punching device for processing a chemical container support plate can increase the feed speed during drilling by adopting a method of drilling first and then expanding the hole, so as to shorten the overall time of the punching work, and increase the rotation speed of the expanding tool as the hole expanding proceeds, and reduce the feed speed of the expanding tool to ensure the dimensional accuracy and surface flatness of the opening, and adjust the cooling speed according to the drilling resistance and the workpiece temperature during the drilling process to avoid overheating of the drill bit and ensure the drilling quality.

[0067] In this embodiment, when in use, the plate to be punched is placed on the two support platforms 5, and then the two knobs 505 are manually rotated to drive the two screw rods 506 to rotate. The screw rods 506 cooperate with the threads of the drive plate 507 and drive the two clamping plates 502 to approach each other under the guidance of the guide plate 503, so that the two clamping plates 502 abut against the two sides of the plate, thereby clamping and fixing the plate. The first rotating motor 203 is started to drive the first screw rod 202 to rotate. The first screw rod 202 cooperates with the threads of the square plate 201 to drive the moving frame 2 to move forward and backward. The moving frame 2 drives the moving platform 4 and the support platform 5 to move forward and backward, thereby The front and rear positions are adjusted, and the second screw rod 402 is driven to rotate by starting the second rotating motor 403.

Then, the driving motor 903 and the first electric push rod 602 are started. The driving motor 903 drives the active gear 902 to rotate. The active gear 902 drives the connecting shaft 9 and the drill bit 7 to rotate by meshing with the driven gear 901. The first electric push rod 602 drives the lifting plate 6 to move downward, so that the high-speed rotating drill bit 7 moves downward to achieve drilling of the plate.

[0068] By starting the water pump 11 and the refrigerator 12, the water pump 11 provides the power of water fluid so that the water in the water supply pipe is cooled by the refrigerator 12 and then introduced into the connector 10, and then introduced into the cavity 701 of the drill bit 7 through the cooling channel 904 in the connecting shaft 9, and is exported from the multiple spiral outlets 702 to the reaming cutter 8, so as to realize the cooling of the connecting shaft 9, the drill bit 7 and the reaming cutter 8;

[0069] The resistance of the lifting plate 6 to move downward is monitored by the pressure sensor 603, that is, the drilling resistance of the drill bit 7 is monitored. When the pressure sensor 603 detects that the pressure increases, the controller 28 controls the working speed of the first electric push rod 602 to decrease, and controls the water pump 11 to increase the power, thereby slowing down the speed of the drill bit 7 moving downward to slow down its heating speed, and increasing the speed of the water pump 11 to deliver water to improve the cooling effect of the drill bit 7. During the drilling process, the temperature of the plate is monitored by the temperature sensor 509. When the temperature sensor 509 detects that the temperature increases, the controller 28 controls the refrigerator 12 to increase the power, thereby improving the cooling effect;

[0070] After the drill bit 7 completes drilling, the first electric push rod 602 is controlled to control the lifting plate 6 to continue to move downward until the upper scraping edge 801 of the reaming knife 8 contacts the plate to scrape off the burrs on the top of the plate. The controller 28 controls the two second electric push rods 14 to start, and the two second electric push rods 14 drive the two horizontal plates 15 to move downward synchronously. The horizontal plate 15 drives the arc frame 17 to move downward through the vertical rod 16. The arc frame 17 drives the annular guide rail 18 and the disc 19 to rotate and move downward at the same time. The disc 19 drives multiple guide frames 22 and multiple reaming knives 8 to move horizontally to the side away from the connecting shaft 9 through sliding cooperation with the inclined rod 20, so that the reaming edge 803 contacts the inner wall of the drilled hole of the plate to realize the reaming work. At the same time, the burrs on the bottom of the plate are scraped off by the lower scraping edge 805, and the chamfering of the plate drilled hole is realized by the upper chamfering edge 802 and the lower chamfering edge 804.

[0071] It should be noted that the start timing of the second electric push rod 14 is controlled by the pressure sensor 603 sensing the pressure increase instantly, and at the same time, the controller 28 controls the first electric push rod 602 to stop working, so that the connecting shaft 9 and the drill bit 7 stop moving downward;

[0072] As the hole expansion work proceeds, the cross plate 15 gradually approaches the lifting plate 6, so that the first conductive tube 25 and the second conductive tube 26 approach the lifting plate 6, so that the resistance of the first resistor bar 24 connected to the drive motor 903 decreases, and the rotation speed of the drive motor 903 increases. At the same time, the resistance of the second resistor bar 27 connected to the second electric push rod 14 increases, and the contraction speed of the output end of the second electric push rod 14 slows down, thereby reducing the speed at which the cross plate 15 moves downward, and the speed at which the hole expansion knife 8 moves outward is slowed down, so as to reduce the feed amount of the hole expansion knife 8 per unit time, thereby achieving a more refined hole expansion, chamfering and burr removal effect, thereby ensuring the flatness of the opening surface of the plate.
