DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides two technical solutions:

[0022] Figure 1-4The first embodiment is shown: a steel pipe processing shrinking machine comprises an installation box 1, a mounting frame 2 is fixedly connected to the top of the installation box 1, connecting holes 3 are penetrated on both sides of the installation frame 2, a shrinking component 6 is arranged inside the installation frame 2, a guide groove 9 is arranged on the end face of the shrinking component 6, the guide groove 9 is rotatably connected to the inner wall of the installation frame 2 through a guide ring, and the guide ring is fixedly connected to the inner wall of the installation frame 2, a movable plate 7 is slidably connected to the top of the installation box 1, a chuck 8 for fixing the steel pipe is arranged on the top of the movable plate 7, a driving mechanism 4 for driving the shrinking component 6 to move is arranged between the installation box 1 and the shrinking component 6, the driving mechanism 4 drives the movable plate 7 and the chuck 8 to move together, a supporting mechanism 5 for supporting the steel pipe is arranged on the top of the installation box 1 and on the other side of the installation box 1, the supporting mechanism 5 comprises two supporting plates 51, the two supporting plates 51 are fixedly connected to the top of the installation box 1, and a supporting roller 52 is rotatably connected between the two supporting plates 51 through a rotating shaft.

[0023] Through the coordination among the chuck 8, the driving mechanism 4 and the shrinking assembly 6, the centering and limiting of the steel pipe is facilitated, which not only facilitates the shrinking of the steel pipe by the shrinking assembly 6, but also effectively improves the shrinking quality of the steel pipe.

[0024] Figure 1 and 2 A second embodiment is shown, which mainly differs from the first embodiment in that a driving mechanism 4 includes a driving motor 41, which has the function of forward and reverse rotation and is connected to a control system and a power supply through a wire. A threaded rod 42 is fixedly connected to the output end of the driving motor 41, and an end of the threaded rod 42 away from the driving motor 41 passes through the installation box 1 and extends to the interior of the installation box 1. A driving gear 43 is fixedly connected to the surface of the threaded rod 42, and a driving gear ring 44 matched with the driving gear 43 is fixedly connected to the surface of the necking component 6. A threaded sleeve 45 is threadedly connected to the surface of the threaded rod 42, and a connecting block 46 is fixedly connected to the surface of the threaded sleeve 45. The connecting block 46 passes through the installation box 1 and is fixedly connected to the bottom of the movable plate 7. A movable hole 10 is opened through the top of the installation box 1, and the connecting block 46 passes through the installation box 1 through the movable hole 10 and is slidably connected to the movable hole 10.

[0025] Through the setting of the driving mechanism 4, the driving motor 41 drives the steel pipe to move toward the shrinking component 6, and at the same time drives the driving gear ring 44 and the shrinking component 6 to rotate together to shrink the steel pipe.

[0026] When in use, place one end of the steel pipe to be processed on the supporting roller 52, and the other end of the steel pipe passes through the chuck 8 so that the end of the steel pipe to be shrunken passes through the chuck 8. Adjust the chuck 8 to fix the steel pipe, and turn on the drive motor 41 through the control panel. The drive motor 41 drives the threaded rod 42 to rotate, and the threaded rod 42 rotates and moves together with the threaded sleeve 45 and the movable plate 7. The movable plate 7 moves through the chuck 8 to drive the steel pipe to move toward the shrinking component 6. The threaded rod 42 rotates and drives the gear 43 to rotate together. The drive gear 43 rotates and drives the drive gear ring 44 and the shrinking component 6 to rotate together through the meshing action. The steel pipe moves toward the shrinking component 6 and cooperates with the rotation of the shrinking component 6 to shrink the steel pipe.
