Technical Field

[0001] This utility model relates to the field of threaded pipe production technology, specifically to an auxiliary feeding device for a three-axis thread rolling machine used in threaded pipe production. Background Technology

[0002] Threaded pipe is a type of pipe with a special structure, mainly used to enhance heat transfer efficiency or achieve pipe connection function. During the production process of threaded pipe, a three-axis thread rolling machine is needed to process the end of the round pipe to form a thread that can be connected. Existing three-axis thread rolling machines lack auxiliary feeding devices, requiring manual handling of the round pipe to insert the end into the thread rolling machine for thread rolling. During this process, the round pipe needs to be kept parallel for a long time, which not only wastes manpower and resources, but also easily causes the round pipe to tilt, affecting the processing effect of the three-axis thread rolling machine. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4This utility model provides a technical solution: an auxiliary feeding device for a three-axis thread rolling machine for producing threaded pipes, including a semi-cylindrical bearing plate 1. Guide grooves 101 extending along the length of the bearing plate 1 are provided at both ends of the bottom of the bearing plate 1. A mounting frame 14 is installed below each of the two guide grooves 101 via a hydraulic cylinder 13. A drive motor 6 and a guide bar 3 are respectively provided inside and on one side of the mounting frame 14. The guide bar 3 slides with the guide groove 101, and a push plate 4 protruding from the guide groove 101 is provided at the end of the guide bar 3. The bottom of the guide bar 3 is provided with teeth 301. A T-shaped limiting groove 302 is provided on one side of the guide bar 3. A limiting block 1401 that slides with the limiting groove 302 is provided on the mounting frame 14. A transmission gear 5 is fixedly installed at the output end of the drive motor 6. The transmission gear 5 meshes with the teeth 301 at the bottom of the guide bar 3. A rotatable and height-adjustable adjustment component is provided at the bottom center of the bearing plate 1.

[0020] In this embodiment, a semi-cylindrical cover plate 2 is provided at the top center of the support plate 1. The cover plate 2 and the edge of the support plate 1 are provided with a fixing edge 15, and fixing bolts are provided on the fixing edge 15. By providing the fixing edge 15, the cover plate 2 can be fixed on the support plate 1, and the cover plate 2 can limit and guide the round tube to prevent the round tube from warping up during processing.

[0021] In this embodiment, the inner side of the support plate 1 and the inner side of the cover plate 2 are respectively provided with directional wheels 7 that roll along the length direction of the support plate 1. The directional wheels 7 facilitate the movement of the round tube by the push plate 4, and prevent the surface of the round tube from being scratched by the support plate 1.

[0022] In this embodiment, a base plate 11 is provided at the bottom of the adjustment component, and casters 16 are installed at the bottom of the base plate 11. The casters 16 facilitate the movement of the device and make it easy to adjust the position of the device.

[0023] In this embodiment, the adjustment assembly includes an adjustment cylinder 10 fixedly connected to the base plate 11. An adjustment rod 9 is installed inside the adjustment cylinder 10. The top of the adjustment rod 9 is movably connected to the bottom of the support plate 1 through a bearing seat 8. A wrench 12 is horizontally set at the upper end of the adjustment rod 9. With this configuration, the adjustment rod 9 can be rotated by the wrench 12 during use. The overall height of the adjustment assembly can be adjusted by utilizing the threaded engagement between the adjustment rod 9 and the adjustment cylinder 10, thereby adjusting the overall height of the device. The bearing seat 8 allows the support plate 1 to rotate flexibly, making it convenient to pull out and rotate the round tube after processing one end, and continue processing the other end.

[0024] Working principle:

[0025] In practical use, the cover plate 2 is placed on the support plate 1 by the cooperation of the fixed edge 15 and bolts. The round tube passes through the cover plate 2 from one end of the support plate 1. The height and angle of the round tube are adjusted by adjusting the components and bearing seat 8 so that the round tube can be aligned with the processing position of the three-axis thread rolling machine. The hydraulic cylinder 13 at the end away from the three-axis thread rolling machine is started. The hydraulic cylinder 13 drives the drive motor 6 and the guide bar 3 to move upward until the push plate 4 protrudes upward from the guide groove 101. The drive motor 6 is started. The drive motor 6 drives the transmission gear 5 through the cooperation of the teeth 301 to move the guide plate 4 upward. The guide bar 3 moves, and the push plate 4 pushes the round tube to move until the end of the round tube is inserted into the processing station of the three-axis thread rolling machine. After the processing is completed, the hydraulic cylinder 13 is started again. The hydraulic cylinder 13 extends downward until the push plate 4 is completely submerged in the guide groove 101 and the guide bar 3 is reset. The round tube is pulled out from the processing station of the three-axis thread rolling machine. The bearing plate is rotated 180° horizontally through the bearing seat 8 so that the unprocessed end is aligned with the processing station of the three-axis thread rolling machine. The above operation is repeated until the screw at that end is processed.

[0026] 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.
