Description

Technical Field

[0001] The invention relates to the technical field of marine flange processing, and in particular to a processing device for processing marine flange forgings. Background Art

[0002] Marine flange forgings are indispensable components in the shipbuilding industry and marine engineering. They are mainly used to connect pipes, pipe fittings or equipment to ensure the stability and sealing of the structure. In the manufacturing process of flange forgings, punching is a basic forging process used to make through holes in the blank. This is part of the forging process and is used to form a specific shape and structure of the flange to facilitate connecting two flanges together to achieve fixation and sealing between pipes or equipment.

[0003] The thickness and size of the marine flange are larger than those of the conventional flange. Therefore, the drilling method is generally used to process the circular holes on the flange. During the drilling process, a large amount of metal debris will be generated after the high-speed rotating drill bit contacts the flange, and splashes around the equipment, causing pollution to the surrounding environment of the processing device and endangering the health of the workers. After the drilling process is completed, a large amount of metal debris will remain on the top of the chuck and the outside of the flange. There is a risk of scratches when the workers collect the processed flange, and when placing a new flange for processing, it is also easily affected by the debris remaining on the chuck, resulting in the flange being placed not flat enough, indirectly affecting the subsequent processing quality of the flange. Therefore, the present application provides a processing device for processing marine flange forgings to meet the needs. Summary of the invention

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting a shielding component, the side baffles can move with the displacement of the drilling rig and form a shield on both sides of the drill bit. Then, when the drill bit processes holes on the flange, the flying debris can be blocked by the side baffles, thereby reducing the metal debris flying to the outside of the device during the processing process and providing a better working environment for the staff.

[0018] By providing the supporting feet in the shielding assembly and the flange supporting plate on the base of the clamping jaw, when the shielding assembly moves down with the drill bit to drill a hole, the supporting feet at the bottom end of the side baffle plate contact the flange before the drill bit, so that the supporting feet can squeeze the top of the flange, cooperate with the flange supporting plate on the clamping jaw to support the bottom of the flange, form a vertical clamp on the flange, and then cooperate with the clamping jaw to clamp and fix the flange in the horizontal direction, thereby further enhancing the fixing effect of the flange during the processing process and improving the stability of the flange during the processing process.

[0019] By setting up a chip removal assembly, when the drill bit is performing flange drilling processing, the chip removal assembly can form a circular air curtain outside the drill bit. On the one hand, it can cooperate with the side baffle plate to form a shield for the debris, reduce the flying metal debris, and reduce the workload of the shielding assembly. On the other hand, it can also quickly reduce the outer surface temperature of the debris generated during the processing, avoiding the debris generated during the processing from carrying high temperature and causing safety hazards.

[0020] By setting the chip removal assembly and the guide groove of the jaw base, the jaws on the electric chuck can not only fix and stabilize the flange to be processed, but also maintain a certain gap between the flange and the top of the electric chuck, reserving space for the drilling process of the drill bit, and the debris generated by drilling at the guide groove can accumulate in the guide groove. After the drilling process is completed, the air flow curtain generated by the chip removal assembly can quickly complete the cleaning of the flange and the upper surface of the electric chuck, thereby facilitating the subsequent flange processing.

[0021] By setting up the transmission component, when the drill bit follows the drilling rig to move down and drill a hole, the side baffle will move down and deform synchronously with the drilling rig, thereby causing the pressure block to squeeze the pressure block, causing the connecting frame to bend and deform and drive the annular tube to shift, thereby concentrating the range of the airflow to the working area of ​​the drill bit, providing a good heat dissipation environment for the drill bit, and after the drive seat has completed drilling and is away from the flange, the transmission component drives the chip removal component to reset and perform chip removal work normally, so that the structures of the chip removal component and the shielding component cooperate with each other and complement each other in function, making the technical solution of the entire device more complete.

[0036] The following is a detailed description of a processing device for processing a marine flange forging provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods to implement some known technologies; and the accompanying drawings are only for a more specific description of the embodiments, and are not intended to specifically limit the present invention.

Spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially relative descriptors used herein may be similarly interpreted accordingly.

[0041] like Figures 1 to 10As shown, an embodiment of the present invention provides a processing device for processing marine flange forgings, including a processing table 1, a fixing frame 5 is fixedly connected to the processing table 1, and a servo motor 2 is installed on the inner side of the processing table 1, the driving shaft of the servo motor 2 extends to the top of the processing table 1 and is fixedly connected to an electric chuck 3, and the electric chuck 3 is provided with evenly distributed clamping jaws 4, the processing table 1 and the fixing frame 5 are used to provide installation and fixing positions for various equipment and structures in the processing device, to ensure that the equipment and structures of the entire processing device can have a stable working environment, and can be close to each other to form a matching relationship, and cooperate to complete the punching processing of the flange, the electric chuck 3 and the clamping jaw 4 are used to clamp and fix the flange to be processed, when the electric chuck 3 is working, the clamping jaw 4 can be displaced in the electric chuck 3, so that the inner ring of the flange is squeezed and clamped, and the flange is clamped and fixed, when the servo motor 2 is working, it can drive the electric chuck 3 to rotate as a whole through its driving shaft, and indirectly drive the flange fixed by the electric chuck 3 and the clamping jaw 4 to rotate. , the relative position relationship between the conversion flange and the punching structure is such that the punching device can perform punching processing at different positions on the flange. A hydraulic telescopic rod 6 is fixedly connected to the outside of the top of the fixing frame 5, and the end of the driving rod of the hydraulic telescopic rod 6 is fixedly connected to a driving seat 7. A drilling rig 8 is installed below the driving seat 7, and a drill bit 17 is arranged at the bottom of the drilling rig 8. The hydraulic telescopic rod 6, the driving seat 7, the drilling rig 8 and the drill bit 17 cooperate to form the punching structure of the processing device. When the hydraulic telescopic rod 6 is working, the driving seat 7 and the structure outside the driving seat 7 can be displaced in the vertical direction by the extension and contraction of its driving shaft, and the driving seat 7 can drive the drilling rig 8 to move in the horizontal direction, changing the position of the drill bit 17 above the flange. When the drilling rig 8 is working, the drill bit 17 can be driven to rotate quickly, and the downward pressure brought by the hydraulic telescopic rod 6 can make the drill bit 17 punch corresponding holes on the flange. The hydraulic telescopic rod 6, the driving seat 7 and the drilling rig 8 are all prior art, and their installation methods and working principles are the same as those of the prior art, which will not be described in detail here.

[0042] The shielding component is used to shield the drilling area of ​​the drill bit 17 to avoid a large amount of metal debris splashing. The shielding component is connected to the drilling machine 8. The shielding component can form a certain shielding outside the drilling processing position of the device to reduce the movable space of the debris generated during the processing, indirectly reduce the splashing debris, and improve the safety of the device process; the chip removal component is used to clean the metal debris on the flange and the electric chuck 3 after the drill bit 17 completes the drilling work. The chip removal component is connected to the drilling machine 8. On the one hand, the chip removal component can blow off the debris on the flange and the electric chuck 3 through airflow after the drilling process is completed, and on the other hand, In addition, the airflow can also be used to cool down and block the flying debris during the processing, thereby further enhancing the safety of the device during the processing; the transmission component is used to drive the chip removal component to shift and change the working range of the chip removal component. The transmission component is connected to the shielding component and the chip removal component respectively. The transmission component enables the chip removal component to change the ejection direction of the airflow during the punching process, so that the ejected airflow is concentrated to the punching position, further amplifying the blocking and cooling effects of the chip removal component. After the punching process is completed, the initial state is restored to perform chip removal and cleaning, thereby further improving the function of the chip removal component.

[0043] In this embodiment, if Figures 1 to 4As shown, the outside of the processing table 1 is equipped with a controller 10, and the controller 10 is electrically connected to the servo motor 2, the electric chuck 3, the hydraulic telescopic rod 6, the drive seat 7 and the drill 8. The controller 10 can control the working status of each electrical equipment in the coordination device, so that the servo motor 2, the electric chuck 3, the hydraulic telescopic rod 6, the drive seat 7 and the drill 8 can cooperate with each other to form the entire flange drilling processing flow. The principle and usage of the controller 10 are the same as those in the prior art and will not be elaborated here. The top of the base part of the clamping jaw 4 is higher than the top of the electric chuck 3, and a guide groove 12 is provided on the base part of the clamping jaw 4. The base part of the clamping jaw 4 is symmetrically connected to a flange support plate 13 fixedly outside. The top of the flange support plate 13 is flush with the top of the base part of the clamping jaw 4. The flange is fixed on the electric chuck 3, and the electric chuck 3 is punched later. Therefore, the structure of the base part of the clamping jaw 4 is such that a certain gap is left between the bottom of the flange after it is fixed and the top of the electric chuck 3, which can facilitate the drill bit 17 to penetrate the flange for drilling operations, and at the same time, the The same is true for the guide groove 12 on the base part, which can provide sufficient space for the drill bit 17 to penetrate the flange. Secondly, the end of the guide groove 12 on the base part of the jaw 4 close to the center part of the electric chuck 3 is higher than the end close to the edge part of the electric chuck 3, so that the bottom of the guide groove 12 is inclined. The debris that leaks into the guide groove 12 during the drilling process can slide down along the inclined surface formed by the guide groove 12 and be discharged. The setting of the flange support plate 13 can increase the contact area between the base part of the jaw 4 and the bottom of the flange, thereby enhancing the stability of the flange fixed on the electric chuck 3.

[0044] In this embodiment, if Figures 4 to 7As shown, the shielding assembly includes side baffles 11 symmetrically connected to both sides of the drilling rig 8, and the side baffles 11 are Z-shaped as a whole. The bottom end of the side baffle 11 extends to below the bottom end of the drill bit 17 and is fixedly connected with a support foot 26. The support foot 26 and the outside of the side baffle 11 are fixedly connected with evenly distributed reinforcing ribs. The setting of the reinforcing ribs can further enhance the structural strength of the support foot 26 and the side baffle 11, ensuring that this part of the area will not be deformed during the process of extrusion and limiting the flange. The setting position of the support foot 26 makes the support foot 26 stable during the drilling process. 26 can contact the outer surface of the flange before the drill bit 17, and as the drill bit 17 is pressed down, the pressure of the support foot 26 on the flange will gradually increase, so as to better cooperate with the clamping jaws 4 and the flange support plate 13 to assist in the clamping and fixing of the flange, and further enhance the stability of the flange fixation during the processing. The side baffles 11 are set on both sides of the drill bit 17 to form a shield, and the area outside the drill bit 17 that is not closed by the side baffles 11 is shielded to a certain extent by the fixing frame 5 and the clamping jaws 4, which can block the flying debris, thereby effectively avoiding the addition. The debris generated during the working process splashes at high speed into the space outside the device, affecting the working environment of the entire device. A deformation zone 22 is provided at the bending part of one end of the side baffle 11 close to the outside of the drilling rig 8. The thickness value at the deformation zone 22 is less than the thickness value of the side baffle 11. The outside of the side baffle 11 is fixedly connected with an extended edge 23 facing the deformation zone 22. The setting of the extended edge 23 makes the thickness values ​​of the side baffle 11 and the extended edge 23 greater than the thickness value of the deformation zone 22, thereby guiding the deformation position of the side baffle 11 and controlling the deformation position at the deformation zone 22 to avoid the side baffle 11 The whole is misaligned during the deformation process. The opening of the deformation zone 22 and the thickness of the deformation zone 22 are thinner than other areas on the side baffle 11, which makes the strength value at the deformation zone 22 weaker. When the side baffle 11 is clamped and fixed to the flange by the support feet 26, as the drill bit 17 is pressed down, the side baffle 11 will move with the drill rig 8 and cause corresponding deformation of the side baffle 11 in the deformation zone 22 to adapt to the working position of the drill rig 8 and the drill bit 17, so as to avoid the setting of the side baffle 11 hindering the normal operation of the drill rig 8 and the drill bit 17.

[0045] In this embodiment, if Figures 4 to 8As shown, the chip removal assembly includes an air pump 9 fixedly connected to the outside of the drilling rig 8 and a connecting frame 16 symmetrically connected to the outside of the drilling rig 8. The air pump 9 is electrically connected to the controller 10. The position of the connecting frame 16 corresponds to the position of the side baffle 11. A second connecting end 28 is fixedly connected to the middle of the connecting frame 16, and an annular tube 15 is fixedly connected to the end of the second connecting end 28. The bottom end of the annular tube 15 is sleeved with evenly distributed nozzles 18, and the annular tube 15 is connected to the air pump 9 through a connecting pipe 14. The air pump 9 also works under the control of the controller 10. When the air pump 9 is working, air can be input into the annular tube 15 through the connecting pipe 14, and finally sprayed out through the nozzle 18 at the bottom of the annular tube 15, forming a circle of wind curtain on the outside of the drill bit 17. On the one hand, the temperature of the chips generated in the processing process is quickly reduced by the injection of airflow, and on the other hand, it can also block the chips to a certain extent to avoid controlling the activity range of the chips.

[0046] The annular tube 15 is semicircular in shape, and the connecting frame 16 is C-shaped as a whole. The connecting frame 16 is fixedly connected to the drilling rig 8 via a first connecting end 27, and the thickness of the first connecting end 27 is greater than the thickness of the connecting frame 16. There are two annular tubes 15, one of which is fixedly connected to a limiting frame 19 at one end, and the other is fixedly connected to a limiting head 20 at the other end. The inner side of the limiting frame 19 is adapted to the outer shape of the limiting head 20, and a first weakening groove 21 is provided on the outer side of the limiting frame 19. The semicircular structure of the annular tube 15 allows the two annular tubes 15 to form a whole annular shape after being spliced, and then the airflow ejected by the nozzle 18 at the bottom of the annular tube 15 can form a wind curtain that can also form a circular shape to hold the drill head 17. Surrounding, ensuring that the action range of the wind curtain corresponds to the working area of ​​the drill bit 17, the annular tube 15 and the drilling rig 8 are connected and fixed by the connecting frame 16, so as to ensure the basic position of the annular tube 15, and the connecting frame 16 and the drilling rig 8 are connected by the first connecting end 27 with a larger thickness value, which has higher strength and higher stability, ensuring the stability of the connection relationship between the annular tube 15 and the drilling rig 8, and the setting of the limit frame 19 and the limit head 20 enables the limit frames 19 and the limit heads 20 at the ends of the two annular tubes 15 to dock with each other after the two annular tubes 15 are fixed and stabilized, and at the same time, the cylindrical structure of the limit head 20 cooperates with the C-shaped open structure of the limit frame 19, so that the two annular tubes 15 can deflect around the connection center of the limit head 20 and the limit frame 19 when subjected to external force, and the deflection activity between the annular tubes 15 also drives the limit head 20 to deflect in the first weakened groove 21 until the connection between the limit head 20 and the annular tube 15 contacts the edge position of the opening outside the limit frame 19. The pressing forms a connection and limit between the ends of the two annular tubes 15, limiting the range of the annular tubes 15 when they are offset and moving. The opening of the first weakened groove 21 makes the limit frame 19 thinner and weaker at the opening of the first weakened groove 21. As a result, during the process of inserting the limit head 20 into the limit frame 19, the limit frame 19 can bend and deform at the first weakened groove 21, thereby increasing the opening size of the limit frame 19, facilitating the entry of the limit head 20 and facilitating the connection of the two annular tubes 15 during the installation process.

[0047] In this embodiment, if Figures 4 to 10As shown, the transmission assembly includes a pressure block 24 fixedly connected to the inner side of the side baffle 11 and a pressure block 30 fixedly connected to the outside of the connecting frame 16. The connecting frame 16 is provided with a second weakened groove 29 located between the first connecting end 27 and the second connecting end 28. The outer surfaces of the pressure block 24 and the pressure block 30 are in contact with each other. The second weakened groove 29 is provided on the side of the connecting frame 16 close to the annular tube 15. The outer part of the pressure block 24 is fixedly connected to the limit strip 25. The pressure block 30 is provided with a limit strip 31 that matches the shape of the limit strip 25. The limit strip 25 is sleeved in the limit strip 31. During the drilling process, the hydraulic telescopic rod 6 drives the drill rig 8 and the drill bit 17 to press down, and the drill bit 17 rotates at high speed to drill holes in the flange. During this process, the side baffle 11 will follow the drill rig. 8 moves downward synchronously, and then the side baffle 11 is bent and deformed at the deformation zone 22. After the side baffle 11 is deformed, it drives the pressing block 24 to approach the outside of the connecting frame 16, and then the pressing block 24 squeezes the pressure block 30. After being squeezed by the pressure block 30, the connecting frame 16 is also bent and deformed at the second weakened groove 29, and then the annular tube 15 is driven by the transmission of the second connecting end 28 to produce a corresponding deviation. After the annular tube 15 deviates, the sprayed liquid of the nozzle 18 The direction of the outgoing airflow changes, and the wind curtain tilts toward the contact point between the drill bit 17 and the flange, forming a concentrated airflow, so that the airflow continues to act on the drill bit 17 during the operation of the drill bit 17, assisting the rapid heat dissipation of the drill bit 17 during the operation, preventing the drill bit 17 from being rapidly aged due to long-term high-temperature operation, and further reducing the blocking area for debris, alleviating the workload of the side baffle 11. During the deformation and deviation of the side baffle 11 and the connecting frame 16, the limit bar 25 on the pressure block 24 follows the deviation of the side baffle 11 and slides in the limit groove 31 on the pressure block 30. When the limit bar 25 moves from the bottom end to the top end in the limit groove 31, the limit head 20 is also deflected in the limit frame 19 to fit the opening edge of the limit frame 19, forming a deflection of the annular tube 15 and a limitation on the deformation of the side baffle 11 and the connecting frame 16, thereby avoiding damage caused by excessive deformation of the side baffle 11 and the connecting frame 16.
