[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-6 A mandrel for a seamless tube piercing machine includes a seamless tube piercing machine housing 1, a transverse mandrel 3 slidably connected inside the seamless tube piercing machine housing 1, a piercing drill bit 2 mounted at one end of the transverse mandrel 3, a moving mechanism for moving the transverse mandrel 3 inside the seamless tube piercing machine housing 1, and a driving mechanism for rotating the transverse mandrel 3 inside the seamless tube piercing machine housing 1.

[0023] The moving mechanism includes a first drive motor 5. The first drive motor 5 is bolted to one end of the seamless tube perforation machine box 1. A transverse threaded rod 7 is fixed to the output end of the first drive motor 5. A transverse sliding plate 8 is threaded to the outside of the transverse threaded rod 7. The transverse sliding plate 8 is sleeved on the outside of the transverse spindle 3 and is rotatably connected to the transverse spindle 3 through a bearing.

[0024] A transverse water pipe 6 is provided at one end of the seamless tube piercing machine box 1. The transverse water pipe 6 is installed inside the transverse sliding plate 8 and is connected to the transverse mandrel 3. With the setting of an external water pump, liquid can be injected into the interior of the transverse mandrel 3 through the transverse water pipe 6 and sprayed by the piercing drill bit 2.

[0025] A dovetail slider is fixed to the top of the horizontal sliding plate 8, and a dovetail groove is opened inside the seamless tube piercing machine box 1. The horizontal sliding plate 8 and the seamless tube piercing machine box 1 are slidably connected by the cooperation of the dovetail slider and the dovetail groove. By setting the dovetail slider and the dovetail groove, the horizontal sliding plate 8 can move laterally inside the seamless tube piercing machine box 1. The movement of the horizontal sliding plate 8 can then make the horizontal mandrel 3 move.

[0026] Here, the operation of the first drive motor 5 causes the transverse threaded rod 7 to rotate. The rotation of the transverse threaded rod 7 causes the transverse sliding plate 8 to move laterally inside the seamless tube piercing machine box 1. The movement of the transverse sliding plate 8 causes the transverse mandrel 3 to move laterally inside the seamless tube piercing machine box 1, and then the transverse mandrel 3 to move laterally inside the transverse mounting tube 14. At the same time, the transverse mandrel 3 can move laterally inside the circular rotating ring 4. The movement of the transverse mandrel 3 causes the piercing drill bit 2 to move, and then the piercing drill bit 2 can pierce the inside of the seamless tube.

[0027] The drive mechanism includes a horizontal mounting plate 10, which is fixed inside the seamless tube piercing machine housing 1 and fixedly connected to the seamless tube piercing machine housing 1. A second drive motor 11 is fixed to the bottom of the horizontal mounting plate 10 by bolts. A first bevel gear 12 is fixed to the output end of the second drive motor 11. A second bevel gear 13 is meshed with the top end of the first bevel gear 12. A horizontal mounting tube 14 is fixed inside the second bevel gear 13. The horizontal mounting tube 14 is sleeved on the outside of the horizontal spindle 3 and slidably connected to the horizontal spindle 3. A vertical support plate 9 is rotatably connected to the outside of the horizontal mounting tube 14 through a bearing. The bottom of the vertical support plate 9 is fixedly connected to the seamless tube piercing machine housing 1.

[0028] Multiple horizontal rectangular sliders are evenly distributed and fixed on the outer side of the horizontal spindle 3. A first horizontal rectangular groove is opened inside the horizontal mounting tube 14. The horizontal spindle 3 and the horizontal mounting tube 14 are slidably connected by the cooperation of the horizontal rectangular sliders and the first horizontal rectangular groove. The setting of the horizontal rectangular sliders and the first horizontal rectangular groove allows the horizontal spindle 3 to slide horizontally inside the horizontal mounting tube 14. The rotation of the horizontal mounting tube 14 allows the horizontal spindle 3 to rotate, and the rotation of the horizontal spindle 3 allows the drilling bit 2 to rotate.

[0029] The seamless tube piercing machine housing 1 is also connected to a circular rotating ring 4 via bearings. The circular rotating ring 4 has a second horizontal rectangular slide groove adapted to the horizontal rectangular slider. The circular rotating ring 4 and the horizontal spindle 3 are slidably connected through the cooperation of the horizontal rectangular slider and the second horizontal rectangular slide groove. The horizontal rectangular slider and the second horizontal rectangular slide groove enable the rotation of the horizontal spindle 3 to rotate the circular rotating ring 4, thereby enabling the circular rotating ring 4 to rotate inside the seamless tube piercing machine housing 1, and the horizontal spindle 3 to move laterally inside the circular rotating ring 4.

[0030] Here, the operation of the second drive motor 11 causes the first bevel gear 12 to rotate, the rotation of the first bevel gear 12 causes the second bevel gear 13 to rotate, the rotation of the second bevel gear 13 causes the transverse mounting tube 14 to rotate, the rotation of the transverse mounting tube 14 causes the transverse mandrel 3 to rotate, the transverse mandrel 3 can rotate inside the transverse sliding plate 8, and the rotation of the transverse mandrel 3 causes the piercing drill bit 2 to rotate, so that the transverse mandrel 3 can rotate while moving, so that the piercing drill bit 2 can pierce the inside of the seamless tube.

[0031] The design of the drive mechanism enables the transverse spindle 3 to achieve precise axial movement while maintaining high-speed rotation, making the piercing process more continuous and stable. This solves the technical problem that rotation and feed motion cannot be synchronized in traditional equipment, simplifies the processing flow, shortens the processing time per piece, improves the degree of automation, and reduces manual intervention.

[0032] Working principle: The operation of the first drive motor 5 enables the transverse threaded rod 7 to rotate. The rotation of the transverse threaded rod 7 enables the transverse sliding plate 8 to move laterally inside the seamless tube piercing machine box 1. The movement of the transverse sliding plate 8 enables the transverse mandrel 3 to move laterally inside the seamless tube piercing machine box 1, and then enables the transverse mandrel 3 to move laterally inside the transverse mounting tube 14. At the same time, the transverse mandrel 3 can move laterally inside the circular rotating ring 4. The movement of the transverse mandrel 3 enables the piercing drill bit 2 to move, and thus enables the piercing drill bit 2 to pierce the inside of the seamless tube.

[0033] The operation of the second drive motor 11 causes the first bevel gear 12 to rotate. The rotation of the first bevel gear 12 causes the second bevel gear 13 to rotate. The rotation of the second bevel gear 13 causes the transverse mounting tube 14 to rotate. The rotation of the transverse mounting tube 14 causes the transverse mandrel 3 to rotate. The transverse mandrel 3 can rotate inside the transverse sliding plate 8. The rotation of the transverse mandrel 3 causes the piercing drill bit 2 to rotate. Thus, the transverse mandrel 3 can move and rotate at the same time, so that the piercing drill bit 2 can pierce the inside of the seamless tube.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
