The springs 381 are deformed to absorb the downward force of the upper plate 372 when it moves downwards, so as to play a role of buffering, so as to avoid excessive downward force when the elastic pressing assembly 37 moves downward to the pressing position. And cause the damage of this germ tube 10. The return elastic force accumulated by each spring 381 will be transmitted to the top 14 of the germ tube 10 through the corresponding gasket 380, the first nut 378 and the lower plate 371, so as to exert a force on the top 14 towards the carrying plate. 34 directions of stretch. In this way, the carrier plate 34 and the elastic pressing assembly 37 are elastically clamped on the germ tube 10 .

Referring to Fig. 8, Fig. 10 and Fig. 11, proceed to step S2, turn on the second control switch 63 to control the operation of the drive cylinder 423 of the mobile drive mechanism 42, so that the drive cylinder 423 drives the master mold through the sliding frame 422 41 moves forward along the front-back direction X to the working position. At this time, the female mold 41 is aligned with the male mold 51 , and the surrounding surfaces 416 of the female mold 41 abut against the outer peripheral surface 12 of the embryonic tube 10 .

Referring to FIG. 8 , FIG. 9 , FIG. 11 and FIG. 12 , then proceed to step S3 , controlling the control unit 61 to control the operation of the motor 351 of the rotary drive assembly 35 . When the motor 351 is in operation, it drives the bearing plate 34 around the first rotation direction R1 through the first gear plate 353, the transmission chain 355, the second gear plate 354 and the transmission shaft 352. The first axis A1 rotates. Since the bearing disc 34 and the elastic resisting assembly 37 of the clamping and rotating device 3 clamp the germ tube 10 with elastic force, the bearing disc 34 will simultaneously drive the germ tube 10 and the elastic tube 10 during rotation. The pressing assembly 37 rotates along the first rotation direction R around the first axis A1. Since the surrounding surfaces 416 of the female mold 41 abut against the outer peripheral surface 12 of the embryonic tube 10, the embryonic tube 10 will drive the female mold 41 along a direction opposite to the first rotation direction R1 during the rotation of the embryonic tube 10. The second direction of rotation R2 rotates around the second axis A2. Thereby, the frictional force between the embryo tube 10 and the mother mold 41 can be reduced, so that the embryo tube 10 can rotate around the first axis A1 smoothly.

Referring to FIG. 8 , FIG. 10 , FIG. 13 and FIG. 14 , proceed to step S4 , control the control unit 61 to control the power unit 524 to drive the drive cylinder 523 to operate. When the drive cylinder 523 is in operation, it will drive the male mold 51 to move along the stamping direction D1 through the movable frame 522. During the movement, the male mold 51 will apply pressure to the embryo tube through the pressing surface 514 of the annular protrusion 513. The inner peripheral surface 11 of 10 drives the embryonic tube 10 to move towards the mother mold 41 . Since the stop wall 342 blocks the outer peripheral surface 12 of the embryo tube 10, the stop wall 342 can support the bottom of the embryo tube 10 to prevent it from moving when the male die 51 presses the embryo tube 10. or out of shape. In addition, since the female mold 41 blocks the outer peripheral surface 12 of the embryonic tube 10 through the surrounding surfaces 416 respectively located at the upper and lower ends of the annular groove 415, the male mold 51 presses the embryonic tube 10 in the process of The germ tube 10 can be smoothly punched into the annular groove 415 .

When the germ tube 10 is punched to the outer peripheral surface 12 in the annular groove 415 When a part is attached to the concave surface 414 , the pressing surface 514 and the concave surface 414 jointly press the germ tube 10 to form a convex structure protruding from the outer peripheral surface 12 . At this time, the driving cylinder 523 stops driving the male die 51 to move so as to position it at the stamping position. Since the pressing surface 514 is in a convex arc and the concave surface 414 is in a concave arc, stress concentration during the process of squeezing the germ tube 10 can be reduced to avoid damage to the germ tube 10 .

Referring to 9, Fig. 13, Fig. 15 and Fig. 16, since the male die 51 is pivotally connected to the movable frame 522, the embryonic tube 10 will drive the male die 51 around the first rotation direction R1 during the rotation process. The third axis A3 rotates. Thereby, the friction force between the embryo tube 10 and the male mold 51 can be reduced, so that the embryo tube 10 can rotate around the first axis A1 smoothly. During rotation, the annular projection 513 of the male mold 51 cooperates with the annular groove 415 of the female mold 41 to continuously squeeze the clamping and rotating device 3 (as shown in FIG. 3 ) to drive the rotation. The embryonic tube 10 can continuously form the convex structure on the embryonic tube 10 . When the clamping and rotating device 3 drives the embryo tube 10 to rotate continuously by 360 degrees, the outwardly convex structure forms a ring-shaped flange 15 , so that the embryo tube 10 forms a tube 1 with the flange 15 . After the embryonic tube 10 is molded into the pipe fitting 1 with the flange 15, since the height of the pipe fitting 1 along the vertical direction Z is shorter than the height of the embryonic tube 10 along the vertical direction Z, through the elastic resistance The elastic force exerted by the bottom plate 371 of the pressing assembly 37 on the top end 14 can ensure that the bottom plate 371 can still press against the top end 14 after the embryo tube 10 is formed into the pipe fitting 1, so that the clamping rotation can be improved. The stability of the clamping of the device 3.

Referring to FIG. 8 , FIG. 9 and FIG. 12 , finally proceed to step S5 , control the control unit 61 to control the motor 351 of the rotation drive assembly 35 to stop operating, so that the clamping and rotating device 3 stops driving the pipe 1 to rotate. At the same time, the control unit 61 is controlled to control the power unit 524 (as shown in FIG. 10 ) to drive the drive cylinder 523 to operate, so as to drive the male mold 51 to move along the reset direction D2 and return to the initial position through the movable frame 522 .

Referring to Fig. 4, Fig. 7 and Fig. 16, then, close the first control switch 62, make the drive cylinder 361 of the mobile drive assembly 36 drive the elastic pressing assembly 37 to move upward and return to the original position, the The lower plate 371 of the elastic resisting assembly 37 can move away from the top end 14 of the tube 1 . Turn off the second control switch 63 to make the driving cylinder 423 of the moving drive mechanism 42 drive the female mold 41 to move backward and return to the non-working position, and the female mold 41 can move away from the outer peripheral surface 12 of the pipe 1 . Finally, the tube 1 can be taken out from the clamping and rotating device 3 .

Referring to FIG. 16 , when the pipe fitting 1 is used subsequently, concrete materials can be poured into the pipe fitting 1 to make cylindrical metal members such as barrels and pipes. By surrounding the outer periphery of the concrete material, the pipe fitting 1 can protect the concrete material to prevent external harmful substances from corroding the concrete material, so as to improve the service life of the metal component. At the same time, the pipe fitting 1 can also increase the toughness and tensile strength of the aluminum member. In addition, the flange 15 of the pipe fitting 1 can prevent the pipe fitting 1 from slipping due to the interface problem with the concrete material, and at the same time, it can be used as a tenon when the transfer equipment or the vehicle moves the metal member, and can lift the pipe fitting 1. The convenience and safety of the components in handling.
