[0002] Rolling hardening of pipe fittings is a surface modification technology used to improve the hardness, fatigue strength, and corrosion resistance of metal pipe fittings. Rolling hardening involves rolling the surface of the fitting with a hard roller, causing plastic deformation.

DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example

[0024] like Figures 1 to 2 and Figure 5As shown, the present invention proposes a pipe joint surface strengthening device, comprising a chassis 1, and also comprising two sets of clamping mechanisms mounted on the chassis 1, the clamping mechanisms clamping guide mechanisms, the guide mechanisms being used to convey and position the pipe joint 6, the clamping mechanisms comprising support plates 2 fixedly mounted on both sides of the chassis 1, two first push rod motors 201 fixedly mounted on the support plates 2, and arc-shaped clamping blocks 202 fixedly mounted on the output shafts of the first push rod motors 201. The guide mechanism comprises a vertical rod 3 located between the two arc-shaped clamping blocks 202, the vertical rod 3 being provided with two grooves 301 corresponding to the arc-shaped clamping blocks 202, a plurality of flexible connecting pieces 302 fixedly mounted on the vertical rod 3, a tensioning rod 303 fixedly mounted on the flexible connecting piece 302, and a conveying wheel 304 rotatably mounted on the tensioning rod 303. The two first push rod motors 201 located on the same horizontal plane drive the arc-shaped clamping block 202 to move into the groove 301 to fix the vertical rod 3, and the clamping mechanisms on the upper and lower sides can clamp and fix the vertical rod 3 independently. When installing the pipe joint 6, first put the pipe joint 6 on the vertical pole 3. At this time, the upper clamping mechanism fixes the vertical pole 3. At this time, the pipe joint put on the vertical pole 3 will rest on the output shaft of the upper first push rod motor 201. After a certain number of pipe joints 6 are put on, the lower clamping mechanism can be used to fix the vertical pole, so that the output shafts of the two upper first push rod motors 201 can be retracted. At this time, the pipe joint 6 put on the vertical pole 3 will move downward under the action of gravity and rest on the output shaft of the lower first push rod motor 201. Then, the upper first push rod motor 201 is fixed to the vertical pole 3 again, and the lower first push rod motor 201 cancels the fixation on the vertical pole 3, so that the vertical pole 3 can always remain in a fixed state, and the pipe joint 6 can slide into multiple tensioning rods 303 through the vertical pole 3.

[0025] It should be noted that the maximum number of pipe joints 6 that can be mounted on the upright pole 3 at a time depends on the ratio of the distance between the two grooves 301 to the length of a single pipe joint 6 , and that circumferential positioning is performed between the grooves 301 and the arc-shaped clamping block 202 .

[0026] The guide mechanism includes an expansion assembly that adjusts the diameter of the guide mechanism. The expansion assembly comprises connecting rods 305 rotatably mounted on the upper and lower sides of the tensioning rod 303. A connecting disk 306 is rotatably mounted on multiple connecting rods 305 on the same side, and a second push rod motor 307 is fixedly mounted between the two connecting disks 306. The second push rod motor 307 is retracted and retracted to adjust the distance between the two connecting disks 306, driving the upper and lower connecting rods 305 to rotate synchronously. The rotating connecting rod 305 pushes the multiple tensioning rods 303 to contract or expand, allowing the multiple tensioning rods 303 to use the inner diameters of the pipe joint 6 of different sizes and to position the axis of the pipe joint 6.

[0027] like Figure 4 As shown, this embodiment also includes a rolling reinforcement mechanism installed on the chassis, the rolling reinforcement mechanism includes multiple rollers 404, the rolling reinforcement mechanism adjusts the diameter of the circle formed by the multiple rollers 404, and drives the multiple rollers 404 to rotate.

[0028] Furthermore, the rolling reinforcement mechanism includes a first gear 4 and a second gear 401 rotatably mounted on the chassis 1, the first gear 4 and the second gear 401 are meshed with each other, a motor is fixedly mounted in the chassis 1, the output shaft of the motor is coaxially fixedly connected to the second gear 401, a support ring 402 is fixedly mounted on the first gear 4, a plurality of adjustment rods 403 are slidably mounted on the support ring 402, the roller 404 is rotatably mounted on the adjustment rod 403, a transmission rod 405 is rotatably mounted on the adjustment rod 403, an adjustment ring 406 and a third push rod motor 407 are rotatably mounted on the first gear 4, the other end of the transmission rod 405 is rotatably connected to the adjustment ring 406, and the output shaft of the third push rod motor 407 is rotatably connected to the adjustment ring 406. When rolling the pipe joint 6, first, the third push rod motor 407 drives the adjusting ring 406 to rotate, and the rotating adjusting ring 406 will drive the adjusting rod 403 to slide, and the sliding adjusting rod 403 will drive the multiple rollers 404 to move, so as to adjust the size of the circular diameter formed by the multiple rollers 404, and then make the multiple rollers 404 squeeze on the pipe joint 6, and then start the motor to drive the second gear 401 to rotate, the rotating second gear 401 will drive the first gear 4 to rotate, and the rotating first gear 4 will drive the multiple rollers 404 to rotate, so that the rollers 404 evenly roll the pipe joint 6.

[0029] A flow hole is provided in the middle of the first gear 4, through which multiple tension rods 303 extend into the interior of the chassis 1. A collection box is fixedly mounted within the chassis 1 and directly below the multiple tension rods 303. After rolling, the pipe joints 6 fall through the flow hole into the collection box for unified collection.

[0030] like Figure 3As shown, in this embodiment, a pressure-applying mechanism is installed on the chassis 1, and the applying mechanism includes a mounting base 5 fixedly installed on both sides of the chassis 1, and a fourth push rod motor 501 is fixedly installed on the mounting base 5, and a pressure ring 502 is fixedly installed on the output shaft of the two fourth push rod motors 501, and a plurality of slides 503 are fixedly installed on the pressure ring 502, and a pressure plate 504 is slidably installed in the slide 503, and a fifth push rod motor is fixedly installed in the slide 503, and the output shaft of the fifth push rod motor is fixedly connected to the pressure plate 504. During rolling, the multiple rollers 404 in the lower pipe joint 6 are squeezed and cannot be lowered. At this time, downward pressure is applied to the upper pipe joint 6 by multiple pressure plates 504, which can drive the multiple pipe joints 6 stacked on each other to move downward, thereby realizing the downward feeding of the pipe joint 6. The fifth push rod motor can drive the pressure plate 504 to extend and retract, so that the pressure plate 504 can contact the pipe joint 6, and the fourth push rod motor 501 can drive the pressure ring 502 to move downward, thereby driving multiple pipe joints 6 to move downward.

[0031] Working principle: When installing the pipe joint 6, first put the pipe joint 6 on the vertical pole 3. At this time, the upper clamping mechanism fixes the vertical pole 3. After a certain number of pipe joints 6 are put on, the lower clamping mechanism can be used to fix the vertical pole, so that the output shafts of the two first push rod motors 201 on the upper side are retracted. At this time, the pipe joint 6 put on the vertical pole 3 will move downward under the action of gravity, and then the upper first push rod motor 201 is used to fix the vertical pole 3 again, and the lower first push rod motor 201 cancels the fixation on the vertical pole 3, so that the vertical pole 3 can always remain in a fixed state, and the pipe joint 6 can slide into multiple tensioning rods 303 through the vertical pole 3, so that the pipe joint 6 can be continuously transported and installed.

[0032] The distance between the two connecting plates 306 can be adjusted by extending and retracting the second push rod motor 307, which can drive the connecting rods 305 on the upper and lower sides to rotate synchronously. The rotating connecting rods 305 will push the multiple tensioning rods 303 to contract or expand, so that the multiple tensioning rods 303 can use the inner diameters of the pipe joints 6 of different sizes and position the axial center line of the pipe joint 6.

[0033] When rolling the pipe joint 6, the third push rod motor 407 is first used to drive the roller 404 to move, so that the size of the circular diameter formed by the multiple rollers 404 can be adjusted, and then the multiple rollers 404 are squeezed on the pipe joint 6. Then the motor is started to drive the second gear 401 to rotate. The rotating second gear 401 will drive the first gear 4 to rotate. The rotating first gear 4 will drive the multiple rollers 404 to rotate, so that the rollers 404 roll the pipe joint 6 evenly.

[0034] During rolling, the multiple rollers 404 in the lower pipe joint 6 are squeezed and cannot be lowered. At this time, downward pressure is applied to the upper pipe joint 6 through the multiple pressure plates 504, which can drive the multiple pipe joints 6 stacked on each other to move downward, thereby realizing the downward feeding of the pipe joint 6.
