Description

Technical Field

[0001] The utility model belongs to the technical field of rolling diameter processing of positioning screw pipe joints, and particularly relates to a rolling diameter processing device for the production of positioning screw pipe joints. Background Art

[0002] In the manufacturing industry of positioning screw pipe joints, rolling diameter processing is a basic and crucial process step. Traditional processing means, especially those devices that use a rolling diameter wheel as the active rotating component to directly act on the surface of the positioning screw pipe joint, have exposed several defects in practical applications:

[0003] 1. Energy consumption and wear problems: Under continuous operation, the actively rotating rolling diameter wheel not only has high energy consumption, but also has a large frictional force between the roller and the positioning screw pipe joint, resulting in a fast wear rate of the roller, requiring frequent maintenance and replacement, increasing the operating cost and downtime.

[0004] 2. Processing stress concentration: The actively rotating roller directly acts on the surface of the positioning screw pipe joint, which may cause local stress concentration. Especially when processing materials with high hardness or uneven thickness, it is easy to cause deformation or cracks in the positioning screw pipe joint, affecting the quality of the finished product.

[0005] In view of the above disadvantages, a new design of the rolling diameter processing device is explored, aiming to solve problems such as energy consumption and processing quality of the traditional processing method through an optimized structural design and power transmission method, and promoting the progress of the production technology of positioning screw pipe joints.

[0008] As a preferred embodiment of the present application, the feeding mechanism includes a feeding push block. When feeding, the feeding push block abuts against the end face of the positioning screw pipe joint to push the positioning screw pipe joint to move axially.

[0033] Referring to Figures 1 to 9 , a processing device for the production of a positioning screw union joint 900, comprising a frame 100, a conveying mechanism 200 is arranged on the frame 100, a rolling diameter station, a rolling character station, a flanging station and a tapping station are arranged in sequence along the conveying path of the conveying mechanism 200, and the conveying mechanism 200 sequentially sends the pipe fittings through each station to complete the rolling diameter, rolling character, flanging and tapping processes. A rolling diameter mechanism 500 is assembled in the rolling diameter station, and a rolling character mechanism 600 is assembled in the rolling character station. A flanging mechanism 700 is assembled in the flanging station, and a tapping mechanism 800 is assembled in the tapping station.

[0034] Specifically, the conveying mechanism 200 includes an arranging 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.

Grooves for placing the positioning screw union joint 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 fitting from the arranging track 210 to the rolling diameter station, the second conveying seat 222 is used to convey the pipe fitting from the rolling diameter station to the rolling character station, the third conveying seat 223 is used to convey the pipe fitting from the rolling character station to the flanging station, and the fourth conveying seat 224 is used to convey the pipe fitting from the flanging station to the tapping station. The arranging track 210 is a ramp slideway structure, a blanking port 211 is arranged at the end of the arranging track 210, and a material blocking frame 212 is arranged on one side of the blanking port 211. A material blocking plate 225 is arranged on the side of the first conveying seat 221 facing the arranging track 210.

[0035] A feeding mechanism 300 is assembled in each of the rolling diameter station, the rolling character station, the flanging station and the tapping station. The feeding mechanism 300 is used to send the positioning screw union joint 900 located on the conveying mechanism 200 into the corresponding station. A pushing mechanism 400 is assembled in each of the rolling diameter station, the rolling character station and the flanging station. The pushing mechanism 400 is used to push the processed positioning screw union joint 900 in the station to the conveying mechanism 200. A blanking channel 120 is assembled in the tapping station. The pipe fittings completed with tapping are dropped into the blanking channel 120 through the pushing mechanism 400.

[0036] The conveying frame 220 of the present application is driven by a conveying cylinder 230 to move reciprocally. Its working principle is as follows: During the conveying process, the positioning screw union joint 900 located at the blanking port 211 is blocked by the baffle plate 225 and the baffle frame 212. When the first conveying seat 221 moves below the blanking port 211, the positioning screw union joint 900 falls into the groove of the first conveying seat 221. When the conveying frame 220 moves back, it takes the positioning screw union joint 900 away from the blanking port 211 and conveys it to the rolling diameter station. The feeding mechanism 300 of the rolling diameter station pushes the positioning screw union joint 900 to the rolling diameter mechanism 500 for rolling diameter processing. After the processing is completed, the pushing mechanism 400 of the rolling diameter station pushes the positioning screw union joint 900 completed with rolling diameter processing back to the conveying mechanism 200. At the same time, the conveying frame 220 moves towards the arranging channel 210, and the positioning screw union joint 900 completed with rolling diameter processing falls onto the second conveying seat 222. The conveying methods at the rolling character station, the flanging station and the tapping station are similar to the above process.

[0037] 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 union joint 900 to push the positioning screw union 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 annularly distributed with the positioning screw union joint 900 as the center. During pushing, the push rods 410 push the positioning screw union joint 900 to move axially by abutting against the end face of the positioning screw union joint 900. The number of the push rods 410 is assembled on a pushing push block 420. The pushing push block 420 is driven by a pushing cylinder 430. A vertical plate 110 is assembled on the frame 100. The push rods 410 are slidably assembled and connected with the vertical plate 110.

[0038] In this application, the rolling diameter mechanism 500 includes a rolling diameter collar 510 and a rolling diameter assembly.

[0039] In this application, the rolling character mechanism 600 includes a rolling character collar 610 and a rolling character assembly. During feeding, the feeding mechanism 300 sleeved the positioning screw coupling joint 900 on the rolling character collar 610.

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 is of 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 collar 610 to avoid interference with the action of sleeving the positioning screw coupling joint 900 on the rolling character collar 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 the characters on the surface of the positioning screw coupling joint 900.

[0040] 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 collar 510 or the rolling character collar 610.

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.

[0041] In this application, the flanging mechanism 700 includes a crossbar 710, a downward pressing assembly, and a stripping plate. The crossbar 710 is fixedly connected to the frame 100.

The downward pressing cylinder 740 drives the upper die base 760 to press down. Under the action of the downward pressure, the recoiling pins 711 punch holes 903 in the positioning screw union joint 900. The downward pressing bar continues to press down, causing the positioning screw union joint 900 to form an outward bulge 902 centered on the punching hole 903.

[0043] Further, a cushion block cylinder 770 is assembled on the frame 100. The cushion block cylinder 770 is connected to a positioning cushion block 780. During the process of the feeding mechanism 300 pushing the positioning screw union joint 900 to the crossbar 710, the cushion block cylinder 770 drives the positioning cushion block 780 to move to the bottom of the crossbar 710. The function of the positioning cushion block 780 is to prevent the crossbar 710 from deforming during pressing and ensure the processing accuracy of the recoiling and flanging.

[0044] In this application, the tapping mechanism 800 includes a tapping seat 810 and a tapping machine 820.
