Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe processing equipment, and in particular to a device for simultaneous cold drawing and forming of internally threaded steel pipes. Background Technology

[0002] Internally threaded steel pipes have wide applications in petroleum, chemical, and machinery manufacturing industries. The traditional method for processing internally threaded steel pipes typically involves first cold-drawing the steel pipe to the required outer diameter, and then machining the inner surface with threads through a separate process.

[0003] This processing method has many disadvantages. For example, the processing steps are complicated, requiring a lot of manpower and time. The steel pipe is easily damaged during multiple processing steps, affecting product quality. Moreover, due to the separation of processing steps, it is difficult to accurately control the matching degree between the thread and the overall size of the steel pipe, resulting in poor product consistency.

[0004] With the increasing demand for efficient and high-precision processing in industrial production, developing a device that can simultaneously perform cold drawing and internal thread forming of internally threaded steel pipes is of great practical significance.

[0005] Therefore, this utility model proposes a device for simultaneous cold drawing and forming of internally threaded steel pipes. Utility Model Content

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a synchronous cold drawing forming device for internally threaded steel pipes, comprising a thread drill bit, and further comprising:

[0008] A drill bit drive assembly consists of a drill bit mounting seat located on top of a threaded drill bit, an arc-shaped mounting plate, and a drive frame. The drive frame is rotatably connected between the drill bit mounting seat and a connecting shaft. The connecting shaft is provided with anti-torsion reinforcing ribs. Both sides of the drive frame are provided with screw sleeves.

[0009] The mounting assembly consists of a lead screw threaded onto a lead screw sleeve, an upper mounting plate, and a lower connecting mounting bracket. The bottom of the upper mounting plate and the top of the lower connecting mounting bracket are both provided with lead screw swivel seats, and the lead screw is rotatably connected within the lead screw swivel seats.

[0010] Furthermore, a first drive motor is provided on the top of the drive frame, the output end of the first drive motor is connected to the connecting shaft, and the bottom of the connecting shaft is connected to the threaded drill bit.

[0011] The beneficial effects of adopting the above-mentioned further solution are: the design makes the thread drill bit operation more efficient, the first drive motor is set at the top of the drive frame to ensure stable installation of the motor, the motor output end is connected to the connecting shaft, the power transmission is direct and efficient, the thread drill bit is connected to the bottom of the connecting shaft, the motor power can be accurately transmitted to the drill bit to achieve stable drilling. This design improves drilling accuracy and efficiency, reduces power loss, and is suitable for various working scenarios that require drilling.

[0012] Furthermore, each of the two lead screw sleeves is provided with an auxiliary connecting plate on the side that is close to each other, and both auxiliary connecting plates are inclined structures, with the inclination of the auxiliary connecting plates increasing sequentially from the side closer to the first drive motor to both sides.

[0015] The beneficial effects of adopting the above-mentioned further solution are as follows: the five arc-shaped mounting plates are distributed in a ring with adjacent included angles being equal. This design has many advantages. The uniform ring layout can make the overall structure more evenly stressed, avoid excessive local pressure, and enhance stability.

The second mounting hole opened at the horizontal end of the upper mounting plate plays a significant role. It can be used to install other related components, which facilitates the functional expansion and upgrading of the equipment. Through the second mounting hole, the components can be connected more tightly and positioned more accurately, making the equipment run more smoothly, improving the overall performance, reducing the installation difficulty, and improving the installation efficiency.

[0020] Furthermore, a processing sleeve is provided on the lower connecting mounting bracket below the drill bit drive assembly, and a first mounting hole is provided at each of the opposite ends of the lower connecting mounting bracket.

The bracket has first mounting holes at both ends, which facilitates the stable connection of the equipment with other structures, ensures convenient installation and accurate positioning, enhances the stability of the overall structure, meets the needs of different installation scenarios, makes the equipment more reliable during operation, and reduces shaking and displacement.

[0022] Furthermore, both sides of the bottom of the upper mounting plate are provided with lower connecting mounting brackets, and a clamping mechanism is provided between the two lower connecting mounting brackets.

[0023] The beneficial effects of adopting the above-mentioned further solution are as follows: This design enhances the practicality and functionality of the equipment. The lower connecting mounting brackets are installed on both sides of the bottom of the upper mounting plate, making the lower connecting mounting brackets more stable and improving the overall structural stability. The clamping mechanism between the two mounting components can effectively clamp and fix the workpiece, preventing the workpiece from shifting during drill bit operation and ensuring processing accuracy.
