[0002] Flanges are widely used connecting components in machinery, pipelines, equipment and other fields. Their core function is to achieve reliable connection and sealing between different components through standardized design.

[0003] After the flange is forged, it needs to be tapped. The internal thread is processed on the flange by a tapping machine to form a mechanical fit with the external thread of the bolt or stud. Then, the helix angle and friction of the thread are used to achieve a fastening connection between the flange and pipes, valves, equipment and other components. Therefore, tapping is an important step in the processing and production of flanges.

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] like Figures 1 to 5As shown, a flange continuous tapping machine according to an embodiment of the present invention comprises a tapping machine body 1; a control assembly 11 is fixedly connected to the top of the tapping machine body 1; a hole opening assembly 12 and a tapping assembly 13 are sequentially mounted on the bottom of the control assembly 11; a conveying frame 14 is fixedly connected to the top of the tapping machine body 1; a support platform 15 is fixedly connected to the side wall of the tapping machine body 1; a telescopic cylinder 16 is fixedly connected to the top of the support platform 15; a push plate 112 is fixedly connected to the output end of the telescopic cylinder 16; a blanking plate 17 is fixedly connected to the side wall of the conveying frame 14; the blanking plate 17 is tilted; a rotating base 18 is fixedly connected to the top of the tapping machine body 1; the rotating base 18 is fixedly connected to a placing table 19 on the top; the placing table 19 is located below the hole opening component 12 and the tapping component 13; a pair of pedestals 110 are symmetrically fixedly connected to the top of the tapping machine body 1; a fixed cylinder 111 is fixedly connected to the top of the pedestal 110; a pair of fixed cylinders 111 are arranged on both sides of the placing table 19; a material box 113 is fixedly connected to the top of the tapping machine body 1. When working, the flange to be tapped is placed on the blanking plate 17, and the gravity of the flange itself is used to make the flange slide toward the inside of the conveying rack 14 in turn. At this time, the flange that slides to the inside of the conveying rack 14 will be pushed forward by the cooperation of the telescopic cylinder 16 and the push plate 112 until it is The flange is transported to the surface of the placement table 19, and then the switch of the fixed cylinder 111 is controlled to push the fixed cylinder 111 in the direction close to the flange and clamp the flange. At this time, the hole opening component 12 is controlled to perform a hole opening operation on the surface of the flange. After the hole opening is completed, the hole opening component 12 is moved away from the surface of the flange and the fixed cylinder 111 is released from the clamping of the flange. Then, the placement table 19 is driven to rotate by controlling the rotating base 18, so that the flange rotates an angle under the drive of the placement table 19, so that the position where the hole has been opened is moved to the bottom of the tapping component 13. At this time, the fixed cylinder 111 is used to fix the flange and the hole opening component is controlled. 12 is used to drill holes in new positions of the flanges, and at the same time, the tapping assembly 13 is used to tap the positions where holes have been drilled on the flanges. During this process, a cutting fluid spraying device is required to flush both the drilling and tapping operations. After the flanges have completed the tapping operation, the telescopic cylinder 16 and the push plate 112 are used to push the subsequent flanges, so that the subsequent flanges squeeze the completed flanges into the inside of the material box 113, and the subsequent flanges to be processed are sent to the placement table 19 to wait for tapping. Through the above operations, the flanges can be continuously drilled and tapped, which reduces the replacement time, speeds up the production and processing speed of the flanges, and improves production efficiency.

[0031] like Figure 2 and Figure 5As shown, a plurality of through holes 2 are opened in the middle of the placing table 19; a vacuum adsorption sponge 21 is fixedly connected inside the through hole 2; a wind collecting cover 22 is fixedly connected to the bottom of the placing table 19; the wind collecting cover 22 is sleeved on the through hole 2; a plurality of wireless electric vacuum pumps 23 are fixedly connected to the bottom of the placing table 19; an exhaust pipe 24 is fixedly connected to the output end of the wireless electric vacuum pump 23; the end of the exhaust pipe 24 is fixedly connected to the wind collecting cover 22; the exhaust pipe 24 and the through hole 2 are communicated with each other. When the flange is transported to the surface of the placing table 19 during operation, the wireless electric vacuum pump is controlled to 23 is used to evacuate air, so that the air inside the through hole 2 at the bottom of the flange is extracted through the cooperation of the vacuum adsorption sponge 21, the wind collecting hood 22 and the exhaust pipe 24, and then the vacuum adsorption sponge 21 forms a vacuum adsorption effect on the surface of the flange. At this time, when the flange is moved by the placement table 19, the flange can also be kept in a stable state, reducing the inertial movement during the rotation of the flange and causing the offset, causing the subsequent hole opening and tapping processing to deviate and cause the flange to be damaged. By improving the fixing effect of the flange, the stability of the flange during the tapping process is increased.

[0032] like Figure 2 and Figure 4 As shown, the output end of the fixed cylinder 111 is symmetrically fixed with a pair of fixed protrusions 3; the fixed protrusions 3 are arranged in an arc shape. During operation, by fixing the fixed protrusions 3 to the end of the fixed cylinder 111, when the fixed cylinder 111 is moved to a position close to the flange, the fixed protrusions 3 at the end of the fixed cylinder 111 will first contact the arc surface of the flange. When the position of the flange on the placement table 19 is offset, the pair of fixed protrusions 3 are used to push the edge of the flange and the arc surface of the fixed protrusions 3 to slide, so that the flange is moved closer to the center position, thereby achieving the effect of correcting the position of the flange. At the same time, the pair of fixed protrusions 3 are used to clamp the arc surface of the flange, which is more stable than single-point fixation, so that the problem of sliding will not occur during the processing of the flange.

[0033] like Figure 1 、 Figure 6 and Figure 7As shown, a support frame 4 is fixedly connected to the top of the tapping machine body 1; a dry ice cleaner 41 is fixedly connected to the top of the tapping machine body 1; a delivery pipe 42 is fixedly connected to the output end of the dry ice cleaner 41; the delivery pipe 42 passes through the side wall of the support frame 4 and is fixedly connected to the support frame 4; a cleaning nozzle 43 is fixedly connected to the end of the delivery pipe 42; the cleaning nozzle 43 is arranged facing the surface of the conveying frame 14. When working, by turning on the switch of the dry ice cleaner 41 when the flange plate moves to the surface of the conveying frame 14, the cleaning nozzle 43 sprays dry ice particles onto the surface of the flange plate. After the dry ice particles come into contact with oil stains, they will quickly sublimate and expand in volume, generating a strong impact force, causing the oil stains to shrink, loosen and fall off from the surface of the flange plate, reducing the processing oil stains on the surface of the flange plate, making the subsequent tapping process of the flange plate less susceptible to influence.

[0034] like Figure 7 As shown, the inner wall of the cleaning nozzle 43 is provided with a plurality of spray holes 5; the spray holes 5 are arranged at an angle. When in operation, by providing a plurality of obliquely arranged spray holes 5 on the end face of the cleaning nozzle 43, the dry ice particles can be sprayed in a fan shape, thereby expanding the coverage area of ​​the dry ice particles, increasing the cleaning range of the flange, and improving the cleaning effect.

[0035] like Figure 1 and Figure 6 As shown, a fan 6 is fixedly connected to the top of the support frame 4; an air duct 61 is fixedly connected to the output end of the fan 6; the air duct 61 passes through the side wall of the support frame 4, and an annular air pipe 62 is fixedly connected to the end thereof; a plurality of fixing rods 63 are fixedly connected between the middle part of the annular air pipe 62 and the side wall of the support frame 4; a plurality of auxiliary nozzles 64 are fixedly connected to the middle part of the annular air pipe 62. When working, an annular auxiliary airflow is set around the cleaning nozzle 43 by using the cooperation of the annular air pipe 62 and the auxiliary nozzles 64, and the dry ice particles are pushed outward by the high-pressure auxiliary airflow, thereby increasing the spray range of the dry ice particles, making the dry ice particles more evenly distributed, and improving the effect of dry ice cleaning.

[0036] like Figure 2 and 3 As shown, a buffer groove is provided on the side wall of the conveying frame 14; a plurality of buffer plates 7 are fixedly connected to the inner side wall of the buffer groove; a spring damper 71 is fixedly connected to the end of the buffer plate 7; the spring damper 71 and the buffer groove are slidably connected. When working, the falling flange is buffered by utilizing the spring damper 71 and the buffer plate 7, thereby reducing the possibility of the flange plate impacting and colliding with the side wall of the conveying frame 14 during the falling process, causing the flange plate surface to be deformed and damaged, thereby improving the protection effect of the flange plate.

[0037] like Figure 3As shown, the side wall of the spring damper 71 is fixed with a sponge pad 8; the sponge pad 8 is located on the side of the spring damper 71 close to the blanking plate 17. During operation, by arranging the sponge pad 8 on the side wall of the spring damper 71, when the flange and the spring damper 71 come into contact, the hard collision between the flange and the spring damper 71 is converted into flexible contact, thereby reducing the wear on the surface of the flange.

[0038] like Figure 3 As shown, an elastic cloth 9 is fixed to the top of the buffer groove; the end of the elastic cloth 9 is fixed to the side wall of the spring damper 71. When working, by arranging the elastic cloth 9 on the top of the buffer groove, the elastic effect of the elastic cloth 9 can be utilized to protect the buffer plate 7 inside the buffer groove, reduce the problem of external impurities contacting the buffer plate 7 and causing corrosion to the buffer plate 7, and improve the service life of the buffer plate 7.

[0039] like Figure 3 As shown, a plurality of rollers 10 are rotatably connected to the middle of the blanking plate 17; the plurality of rollers 10 are arranged in an array on the blanking plate 17. During operation, by providing a plurality of rollers 10 on the blanking plate 17, when the flange slides from the blanking plate 17 to the surface of the conveying rack 14, the rolling effect of the rollers 10 is utilized to reduce the problem of the flange getting stuck on the blanking plate 17 and being unable to fall, thereby improving the stability of the flange conveying.

[0040] During operation, the flange to be tapped is placed on the blanking plate 17, and the flange is slid toward the inside of the conveying rack 14 in sequence by its own gravity. At this time, the flange that slides to the inside of the conveying rack 14 will be pushed forward by the cooperation of the telescopic cylinder 16 and the push plate 112 until the flange is conveyed to the surface of the placement table 19, and then the switch of the fixed cylinder 111 is controlled to push the fixed cylinder 111 in the direction close to the flange and clamp the flange. At this time, the hole opening component 12 is controlled to perform a hole opening operation on the surface of the flange. After the hole opening is completed, the hole opening component 12 is moved away from the surface of the flange and the fixed cylinder 111 is released to clamp the flange, and then the placement table 19 is driven to rotate by controlling the rotating base 18, so that the flange rotates an angle driven by the placement table 19, so that the flange is After the hole is opened, it moves to the bottom of the tapping assembly 13. At this time, the fixing cylinder 111 is used to fix the flange, and the hole opening assembly 12 is used to open a hole in the new position of the flange. At the same time, the tapping assembly 13 is used to tap the position where the flange has been opened. In this process, a cutting fluid spray device is required to flush both the hole opening and the tapping. After the flange completes the tapping operation, the telescopic cylinder 16 and the push plate 112 are used to push the subsequent flange, so that the subsequent flange squeezes the completed flange into the inside of the material box 113, and the subsequent flange to be processed is sent to the placement table 19 to wait for tapping. Through the above operations, the flange can be continuously opened and tapped, which reduces the replacement time, speeds up the production and processing speed of the flange, and improves production efficiency.

[0041] When the flange is transported to the surface of the placement table 19, the wireless electric vacuum pump 23 is controlled to evacuate the air, so that the air inside the through hole 2 at the bottom of the flange is extracted through the cooperation of the vacuum adsorption sponge 21, the wind collecting hood 22 and the exhaust pipe 24, and then the vacuum adsorption sponge 21 forms a vacuum adsorption effect on the surface of the flange. At this time, when the flange is driven to move by the placement table 19, the flange can also be kept in a stable state, reducing the inertial movement during the rotation of the flange and causing the offset, causing the subsequent hole opening and tapping processing to deviate and cause the flange to be damaged. By improving the fixing effect of the flange, the stability of the flange during the tapping process is increased.

[0042] By fixing a fixed protrusion 3 to the end of the fixed cylinder 111, when the fixed cylinder 111 moves to a position close to the flange, the fixed protrusion 3 located at the end of the fixed cylinder 111 will first contact the curved surface of the flange. When the position of the flange on the placement table 19 is offset, the edge of the flange and the curved surface of the fixed protrusion 3 are pushed forward to slide, so that the flange is moved closer to the center position, thereby achieving the effect of correcting the position of the flange. At the same time, the curved surface of the flange is clamped by a pair of fixed protrusions 3, which is more stable than single-point fixation, so that the problem of sliding will not occur during the processing of the flange.

[0043] When the flange moves to the surface of the conveyor rack 14, the dry ice cleaner 41 is turned on, so that the cleaning nozzle 43 sprays dry ice particles onto the surface of the flange. After the dry ice particles come into contact with oil, they will quickly sublime and expand in volume, generating a strong impact force, causing the oil to shrink, loosen, and fall off from the surface of the flange, thereby reducing the processing oil on the surface of the flange and making the flange less susceptible to being affected during subsequent tapping processing.

[0044] By providing a plurality of obliquely arranged spray holes 5 on the end face of the cleaning nozzle 43, the dry ice particles can be sprayed in a fan shape, thereby expanding the coverage area of ​​the dry ice particles, increasing the cleaning range of the flange, and improving the cleaning effect.

[0045] By using the annular air pipe 62 and the auxiliary nozzle 64, an annular auxiliary airflow is provided around the cleaning nozzle 43. The high-pressure auxiliary airflow pushes the dry ice particles outward, thereby increasing the spray range of the dry ice particles, making the dry ice particles more evenly distributed, and improving the dry ice cleaning effect.

[0046] By utilizing the spring damper 71 and the buffer plate 7 to cushion the falling flange, the possibility of the flange impacting and colliding with the side wall of the conveyor frame 14 during the falling process, which may cause deformation and damage to the flange surface, is reduced, thereby improving the protection effect of the flange.

[0047] By arranging the sponge pad 8 on the side wall of the spring damper 71, when the flange and the spring damper 71 come into contact, the hard collision between the flange and the spring damper 71 is transformed into a flexible contact, thereby reducing the wear on the flange surface.

[0048] By arranging elastic cloth 9 on the top of the buffer groove, the elastic effect of the elastic cloth 9 can be utilized to protect the buffer plate 7 inside the buffer groove, reducing the problem of external impurities contacting the buffer plate 7 and causing corrosion to the buffer plate 7, thereby improving the service life of the buffer plate 7.

[0049] By providing multiple rollers 10 on the blanking plate 17, when the flange slides from the blanking plate 17 to the surface of the conveying frame 14, the rolling effect of the rollers 10 is utilized to reduce the problem of the flange getting stuck on the blanking plate 17 and unable to fall, thereby improving the stability of the flange conveying.
