[0051] When the movable frame 40 moves toward a T-shaped block 43, the top shaft 403 on the rotating frame 401 slides into the inclined groove 45. When the top shaft 403 moves to the innermost end of the inclined groove 45, the movable frame 40 continues to be translated, and the rotating frame 401 rotates.

[0055] An inner roller 1 36 is fixedly provided on the rotating plate 35.

At the same time, an outer roller 38 is rotatably provided on the rotating plate 35 and located on one side of the inner roller 2 37. The two outer rollers 38 are symmetrically arranged on the rotating plate 35.

[0056] A motor 4 is fixedly provided on the rotating plate 35, and the motor 4 is not shown in the drawing. The output end of the motor 4 is fixedly connected to the axis of the outer roller 38 to control the rotation of the outer roller 38. The stainless steel pipe fitting is located between the inner roller 2 37 and the outer roller 38, so that the inner roller 2 37 and the outer roller 38 grind the inner and outer sides of the stainless steel pipe wall.

[0057] A driving assembly 30 is provided on the rotating plate 35. The driving assembly 30 includes two levers 301. One end of the lever 301 is sleeved on the driving shaft 344. The two levers 301 are symmetrically arranged, and one side of the lever 301 is slidably connected to the driven shaft 372. The rotation of the lever 301 can move the driven shaft 372. A convex rod 306 is fixedly connected to the lever 301.

[0058] The driving assembly 30 also includes a telescopic rod, which includes an outer tube 302 and an inner rod 303. A fixed plate 310 is fixedly provided on the rotating plate 35. The outer tube 302 is slidably arranged on the fixed plate 310. The inner rod 303 is slidably installed in the outer tube 302. One side of the inner rod 303 and the outer tube 302 are fixedly connected with a side block 308.

The output end of the motor 5 309 is fixedly connected with a bidirectional lead screw 307, and the bidirectional lead screw 307 is threadedly connected to the side block 308.

[0059] The two side blocks 308 are symmetrically arranged on the bidirectional screw 307. The bidirectional screw 307 is driven to rotate by the motor 309 to control the two side blocks 308 to move toward or in the opposite direction, so that the outer tube 302 and the inner rod 303 can slide alternately, so as to realize the extension or shortening movement of the telescopic rod. The end of the inner rod 303 away from the outer tube 302 is fixedly connected with a pull plate 304, and the pull plate 304 is provided with symmetrically distributed straight grooves 305, which are slidably connected to the protruding rod 306.

[0060] The two driven shafts 372 are controlled to rotate synchronously by the pull plate 304, and the two driven shafts 372 drive the two sliders 371 to move, and drive the two sliders 371 to move smoothly, and adjust the two inner rollers 37 to fit the inner wall of the stainless steel pipe fitting. A cylinder four 39 is fixedly connected to the end of the outer tube 302 away from the inner rod 303, and a driving motor 390 is fixedly connected to the output end of the cylinder four 39, and a cutting tool 391 is fixedly connected to the output end of the driving motor 390.

[0061] Cylinder four 39 pushes the cutting tool 391 to move horizontally, so that the cutting tool 391 extends toward the stainless steel pipe fitting. The cutting tool 391 is located between the two inner rollers 2 37. When the cutting tool 391 processes the stainless steel pipe fitting, the inner roller 2 37 is located inside the stainless steel pipe fitting, which helps to support the thin-walled stainless steel pipe and avoid deformation of the thin-walled stainless steel pipe fitting.

[0062] Here’s how it works:

[0063] The produced long thin-walled stainless steel pipe fittings are cut into thin-walled stainless steel pipe fittings of required length, and then the thin-walled stainless steel pipe fittings are moved horizontally toward the tooling seat 2, and the thin-walled stainless steel pipe fittings are smoothly moved into the V-shaped groove 21. When the thin-walled stainless steel pipe fittings are located in the V-shaped groove 21, the ends of the two thin-walled stainless steel pipe fittings are located at the two ends of the tooling seat 2. Thereafter, the cylinder three 28 controls the pressing plate 26 to move toward the thin-walled stainless steel pipe fittings, and the pressing plate 26 moves to press and fix the thin-walled stainless steel pipe fittings.

[0064] Then, the rack 16 moves, and the gear 25 is used to control the tooling seat 2 to rotate, so that the tooling seat 2 can rotate and adjust the angle of the thin-walled stainless steel pipe fittings, so that the thin-walled stainless steel pipe fittings can be rotated 90 degrees. Then, the thin-walled stainless steel pipe fittings need to be supported and fixed. Specifically, when the mobile frame 40 moves toward a T-shaped block 43, the top shaft 403 on the rotating frame 401 slides into the inclined groove 45. When the top shaft 403 moves to the innermost end of the inclined groove 45, the mobile frame 40 continues to be translated, and the rotating frame 401 rotates. At this time, the top shaft 403 moves upward, lifts up the T-shaped block 43, and supports the T-shaped block 43. If the mobile frame 40 is translated in the opposite direction, the top shaft 403 moves in the opposite direction. At this time, the T-shaped block 43 moves downward, and when the rotating frame 401 is reset by the torsion spring 404, the rotating frame 401 contacts the limit block 402 to support the rotating frame 401.

[0065] Then, the lead screw 32 is rotated to control the moving plate 34 to move downward, so that the moving plate 34 moves the inner roller 1 36 and the inner roller 2 37 downward, so that the inner roller 1 36 and the inner roller 2 37 are moved into the stainless steel pipe fitting, and then the two-way lead screw 307 is rotated to control the two side blocks 308 to move toward each other, retract the telescopic rod, pull the pull plate 304 to move, control the two levers 301 to rotate toward each other, and push the inner roller 2 37 to move toward the cutting tool 391 until the inner roller 2 37 fits against the inner wall of the thin-walled stainless steel pipe fitting, and the cutting tool 391 moves with the outer tube 302 and gradually moves toward the thin-walled stainless steel pipe fitting.

[0066] Then, the motor three 343 is used to control the rotation of the rotating plate 35, and the inner roller one 36 and the inner roller two 37 are used to grind the inner wall of the thin-walled stainless steel pipe fitting. According to actual needs, the cylinder four 39 is started to control the cutting tool 391 to move toward the thin-walled stainless steel pipe fitting, and the thin-walled stainless steel pipe fitting is cut. The thin-walled stainless steel pipe fitting is automatically processed, and the forming process is stable and reliable.

[0067] After processing one end of the thin-walled stainless steel pipe fitting, rotate the fixture seat 2, rotate 180 degrees, so that the position of the end of the thin-walled stainless steel pipe fitting is interchanged, and then use the processing mechanism on another rotating plate 35 to process the end of the thin-walled stainless steel pipe fitting, and the processing method is the same as above.

[0068] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
