[0002] Flanging processing is one of the key steps in the manufacture of positioning screw pipe couplings, mainly used to enhance the strength and sealing performance of the edges of positioning screw pipe couplings. Existing flanging processing devices often have complex structures, including many moving parts and precision components, such as complex transmission systems, multi-stage positioning devices, and independent die replacement mechanisms. This complexity not only increases the manufacturing cost and maintenance difficulty of the equipment, but also may lead to an increase in the failure rate during the processing, affecting production continuity and product qualification rate.

[0003] Therefore, based on the above situations in the prior art, the present application has been further designed and improved. Summary of the Utility Model

[0008] As a preferred embodiment of the present application, the pushing mechanism includes a number of push rods annularly distributed around the positioning screw pipe coupling. During pushing, the push rods push the positioning screw pipe coupling to move axially by abutting against the end face of the positioning screw pipe coupling.

[0032] Refer to Figures 1 to 9, a processing device for the production of positioning screw couplings 900, including a frame 100, on which a conveying mechanism 200 is arranged. Along the conveying path of the conveying mechanism 200, a diameter rolling station, a letter rolling station, a flanging station, and a tapping station are arranged in sequence. The conveying mechanism 200 sequentially sends the pipe fittings through each station to complete diameter rolling, letter rolling, flanging, and tapping processing. A diameter rolling mechanism 500 is assembled in the diameter rolling station, and a letter rolling mechanism 600 is assembled in the letter rolling station. A flanging mechanism 700 is assembled in the flanging station, and a tapping mechanism 800 is assembled in the tapping station.

[0033] Specifically, the conveying mechanism 200 includes an alignment track 210 and a conveying frame 220. The conveying frame 220 is connected to the frame 100 through a slide rail, and a conveying cylinder 230 is assembled on one side of the conveying frame 220. Along the conveying path on the conveying frame 220, a first conveying seat 221, a second conveying seat 222, a third conveying seat 223, and a fourth conveying seat 224 are arranged in sequence. Grooves for placing the positioning screw couplings 900 are provided on the first conveying seat 221, the second conveying seat 222, the third conveying seat 223, and the fourth conveying seat 224. The first conveying seat 221 is used to convey the pipe fittings from the alignment track 210 to the diameter rolling station, the second conveying seat 222 is used to convey the pipe fittings from the diameter rolling station to the letter rolling station, the third conveying seat 223 is used to convey the pipe fittings from the letter rolling station to the flanging station, and the fourth conveying seat 224 is used to convey the pipe fittings from the flanging station to the tapping station. The alignment track 210 is a ramp slideway structure, and a blanking port 211 is provided at the end of the alignment track 210. A stop frame 212 is provided on one side of the blanking port 211. A stop plate 225 is provided on the side of the first conveying seat 221 facing the alignment track 210.

[0034] Feeding mechanisms 300 are assembled in the diameter rolling station, the letter rolling station, the flanging station, and the tapping station. The feeding mechanisms 300 are used to send the positioning screw couplings 900 located on the conveying mechanism 200 into the corresponding stations. Pushing mechanisms 400 are assembled in the diameter rolling station, the letter rolling station, and the flanging station. The pushing mechanisms 400 are used to push the processed positioning screw couplings 900 in the stations to the conveying mechanism 200. A blanking channel 120 is assembled in the tapping station, and the pipe fittings that have completed tapping processing fall into the blanking channel 120 through the pushing mechanism 400.

[0035] The conveying rack 220 described in this application is driven by a conveying cylinder 230 to move reciprocally, and its working principle is as follows: During the conveying process, the positioning screw coupling joint 900 located at the blanking port 211 is blocked by the material baffle 225 and the material blocking rack 212. When the first conveying seat 221 moves below the blanking port 211, the positioning screw coupling joint 900 falls into the groove of the first conveying seat 221. When the conveying rack 220 moves back, it takes the positioning screw coupling joint 900 away from the blanking port 211 and conveys it to the rolling diameter station. The feeding mechanism 300 at the rolling diameter station pushes the positioning screw coupling joint 900 to the rolling diameter mechanism 500 for rolling diameter processing. After the processing is completed, the pushing mechanism 400 at the rolling diameter station pushes the positioning screw coupling joint 900 that has completed the rolling diameter processing back to the conveying mechanism 200. At the same time, the conveying rack 220 moves towards the arranging track 210, and the positioning screw coupling joint 900 that has completed the rolling diameter processing falls onto the second conveying seat 222. The conveying methods at the rolling character station, flanging station, and tapping station are similar to the above process.

[0036] Specifically, the feeding mechanism 300 includes a feeding push block 310. During feeding, the feeding push block 310 abuts against the end face of the positioning screw coupling joint 900 to push the positioning screw coupling joint 900 to move axially. The feeding push block 310 is driven by a feeding cylinder 320. The pushing mechanism 400 includes a number of push rods 410 that are annularly distributed around the positioning screw coupling joint 900. During pushing, the push rods 410 push the positioning screw coupling joint 900 to move axially by abutting against the end face of the positioning screw coupling joint 900. The number of push rods 410 is assembled on a pushing block 420, and the pushing block 420 is driven by a pushing cylinder 430. A vertical plate 110 is assembled on the frame 100, and the push rods 410 are slidably assembled and connected with the vertical plate 110.

[0037] In this application, the rolling diameter mechanism 500 includes a rolling diameter sleeve 510 and a rolling diameter assembly. During feeding, the feeding mechanism 300 sleeves the positioning screw coupling joint 900 on the rolling diameter sleeve 510. A connecting shaft is assembled inside the rolling diameter sleeve 510, and the connecting shaft is connected with a rolling diameter driving unit 530 through a sprocket transmission structure 520. The rolling diameter assembly includes a rolling diameter hydraulic cylinder 540. The rolling diameter hydraulic cylinder 540 is connected with a rolling diameter frame, and a rolling diameter wheel 550 is assembled on the rolling diameter frame. During rolling diameter processing, the rolling diameter driving unit 530 drives the rolling diameter sleeve 510 to rotate, thereby driving the positioning screw coupling joint 900 to rotate. The rolling diameter hydraulic cylinder 540 drives the rolling diameter wheel 550 to press forward, and a rolling diameter groove 901 is pressed out on the side surface of the positioning screw coupling joint 900.

[0038] In this application, the rolling character mechanism 600 includes a rolling character ferrule 610 and a rolling character assembly. During feeding, the feeding mechanism 300 sleevs the positioning screw coupling joint 900 on the rolling character ferrule 610. The rolling character ferrule 610 is assembled and connected to the machine frame 100 through a bearing 450. The rolling character assembly includes a rolling character wheel 620, and the rolling character wheel 620 is connected to a rolling character driving unit 640 through a belt pulley transmission structure 630. The rolling character wheel 620 has a D-shaped structure, and the characters to be rolled on the positioning screw coupling joint 900 are arranged on the arc-shaped side surface of the D-shaped structure. In the unprocessed state, the flat side of the D-shaped structure of the rolling character wheel 620 faces the rolling character ferrule 610 to avoid interference with the action of sleeving the positioning screw coupling joint 900 on the rolling character ferrule 610. When performing rolling character processing, the rolling character driving unit 640 drives the rolling character wheel 620 to rotate, and the arc-shaped side surface of the D-shaped structure of the rolling character wheel 620 drives the positioning screw coupling joint 900 to rotate, and at the same time rolls characters on the surface of the positioning screw coupling joint 900.

[0039] To avoid wear of the positioning screw coupling joint 900 due to rotation during processing, the pusher mechanism 400 in the rolling diameter station and the rolling character station further includes a push ring 440, and the push ring 440 is fixedly assembled with the rolling diameter ferrule 510 or the rolling character ferrule 610. A rolling groove is provided on the outer peripheral side of the push ring 440, and a bearing 450 is assembled at the end of the push rod 410, and the outer ring of the bearing 450 is assembled in the rolling groove. The feeding pusher block 310 in the rolling diameter station and the rolling character station is connected to the feeding cylinder 320 through a bearing 450. The above design enables the feeding mechanism 300 and the pusher mechanism 400 to axially limit the positioning screw coupling joint 900 during rolling diameter processing and rolling character processing, and at the same time avoid relative rotation of the positioning screw coupling joint 900 relative to the feeding pusher block 310 and the push ring 440, and avoid wear of the two end faces of the positioning screw coupling joint 900.

[0040] In this application, the flanging mechanism 700 includes a cross arm 710, a pressing-down assembly and a stripping plate. The cross arm 710 is fixedly connected to the machine frame 100. During feeding, the feeding mechanism 300 sleevs the positioning screw coupling joint 900 on the cross arm 710. A number of recoiling needles 711 are arranged on the cross arm 710 in a collinear distribution. The pressing-down assembly includes a fixing plate 720, the fixing plate 720 is assembled and fixed to the machine frame 100 through a number of guiding columns 730, a pressing-down cylinder 740 is assembled on the fixing plate 720, the pressing-down cylinder 740 is connected to an upper template 750, the upper template 750 is slidably assembled with the guiding columns 730, an upper die base 760 is assembled on the upper template 750, and a punching groove corresponding to the recoiling needle 711 is provided on the upper die base 760, and the stripping plate and the upper template 750.

[0041] When flanging is carried out, the feeding mechanism 300 at the flanging station pushes the positioning screw coupling joint 900 forward until the positioning screw coupling joint 900 is sleeved on the cross arm 710. The downward pressure cylinder 740 drives the upper die base 760 to press down. Under the action of the downward pressure, the reverse punching needle 711 punches a hole 903 in the positioning screw coupling joint 900. The downward pressure bar continues to press down, causing the positioning screw coupling joint 900 to form an outward bulge 902 centered on the punched hole 903.

[0042] Furthermore, a cushion block cylinder 770 is assembled on the frame 100. The cushion block cylinder 770 is connected with a positioning cushion block 780. During the process of the feeding mechanism 300 pushing the positioning screw coupling joint 900 to the cross arm 710, the cushion block cylinder 770 drives the positioning cushion block 780 to move to the bottom of the cross arm 710. The function of the positioning cushion block 780 is to prevent the cross arm 710 from deforming when pressing down and to ensure the processing accuracy of reverse punching and flanging.

[0043] In this application, the tapping mechanism 800 includes a tapping base 810 and a tapping machine 820. A second receiving groove 811 for receiving the positioning screw coupling joint 900 is provided in the tapping base 810.

Correspondingly, a first receiving groove 226 for receiving the positioning screw coupling joint 900 is provided on the fourth conveying seat 224. A first positioning groove 227 for positioning the bulge 902 is provided at the top of the first receiving groove 226.
