Description

Technical Field

[0001] This invention relates to the field of automatic pipe threading devices, and more particularly to an automatic pipe threading production line. Background Technology

[0002] In industrial production, pipe processing and connection are fundamental processes in many industries, especially in petroleum, chemical, construction, and HVAC. Pipe connections typically require threading at both ends of the pipe to facilitate threaded connections. Traditional pipe threading methods are mostly manual or semi-automated, which have many drawbacks.

[0003] First, traditional processing methods are inefficient. After the pipes are cut, they need to be manually transported to threading equipment for secondary processing. This process is not only time-consuming and labor-intensive, but also increases potential safety risks during production. Second, due to manual operation, processing accuracy is difficult to guarantee, easily leading to problems such as thread deviation and incomplete threading, thus affecting the reliability and sealing of pipe connections. Furthermore, traditional equipment is usually single-function and cannot integrate multiple processing stages, resulting in complex production line layouts, large footprints, and high equipment investment and maintenance costs.

[0004] Furthermore, with the development of automation and intelligence in manufacturing, the market demand for efficient, precise, and integrated pipe processing equipment is becoming increasingly urgent. While some highly automated equipment has emerged, existing technologies often only allow for single tasks like cutting or threading, or require manual intervention during process transitions. These devices still fall short in achieving full-process automation and integration, failing to fundamentally solve problems such as low production efficiency, poor processing accuracy, and high production costs.

And a communication interface module, used to realize data exchange between the control host and external devices or host computers.

[0018] This invention creatively integrates multiple independent processes—such as material loading, segmented cutting, end-threading, and finished product unloading—that traditionally require multiple machines and manual handling into a single device. This integrated design eliminates unnecessary waiting and manual intervention between processes, thereby achieving automated and continuous production from raw materials to finished products.

[0019] The feeding assembly in this invention, through the coordinated action of the drive rod and the feeding plate, automatically feeds the pipe from the stockpiling area into the processing area step by step, replacing the traditional manual feeding method and ensuring production continuity from the source. During processing, the processing slide is driven by the processing drive unit on the guide rail assembly to move precisely back and forth, allowing the cutting assembly and the second wire threading assembly to move to the preset work position and work in conjunction with the fixed-end stabilizing positioning assembly and the first wire threading assembly. This mobile processing design allows segmented cutting and end-to-end wire threading to be completed on the same production line, significantly reducing the changeover time between equipment.

[0020] After all the pipe processing is completed, the top support unit in this invention precisely lifts the finished pipe from the threading station and guides it through the unloading plate, causing it to automatically roll into the storage rack, thus achieving automated collection of the finished product. The entire process is seamless and requires no manual intervention, greatly improving the overall operating efficiency of the production line. Compared with the traditional decentralized production mode, production efficiency can be increased by more than 100%.

[0021] The production base frame in this invention serves as the load-bearing foundation for all components, and the application of the leveling screw seat ensures the equipment remains stable in various ground environments, eliminating processing errors caused by unstable equipment foundations. The processing slide and sliding positioning assembly are both mounted on the guide rail assembly, and their movement is precisely controlled by the processing drive unit and the positioning drive unit. Simultaneously, displacement sensors monitor their movement position in real time and feed the data back to the control module, forming a closed-loop control system that guarantees sub-millimeter accuracy in cutting length.

[0022] The multi-clamping positioning mechanism in this invention ensures stability during the processing. In each step of cutting and threading, multiple clamping structures, including the stabilizing positioning component, the first clamping module, the second clamping module, the third clamping module, and the clamping fixing module, work together to clamp and support the pipe at multiple points. In particular, the design of the movable clamping structure ensures that the pipe will not shake or shift due to external forces during processing, fundamentally eliminating quality problems such as uneven cutting and skipped threads caused by unstable clamping, significantly improving the processing quality and connection reliability of the finished pipe.

This mechanism, through the movement of the processing slide, allows the cutting component 620 to cut the pipe at a preset position, thereby segmenting the long pipe. The stabilizing positioning component 610 and the sliding positioning component 630 position the pipe from both ends respectively, ensuring the accuracy of the cutting position. The automatic feeding mechanism 700 includes a first stable feeding component 710 disposed on the fixed base and facilitating the extension of the segmented pipe, which has undergone segmented cutting, into the automatic threading mechanism 800; and a second stable feeding component 720 disposed on the processing slide and cooperating with the first stable feeding component 710.

The system includes an automatic threading mechanism 800, comprising a first threading assembly 810 mounted on the fixed base for automatically threading one end of a segmented pipe, and a second threading assembly 820 mounted on the processing slide for automatically threading the other end of the segmented pipe. By moving the processing slide, the first threading assembly 810 and the second threading assembly 820 can respectively thread both ends of the cut pipe, thereby achieving synchronous or sequential processing at both ends.

A leveling screw seat is provided at its bottom end, and the feeding assembly 400 is installed on it. The leveling screw seat can be rotated to adjust the height of the first top support frame 211, so that the top support base frame 210 can remain horizontal even on uneven ground. The second top support frame 212 is arranged parallel to the first top support frame 211, and a leveling screw seat is provided at its bottom end; the second top support frame 212 and the first top support frame 211 work together to enhance the load-bearing capacity of the top support base frame 210; The stabilizing frame 213 is located at the bottom end of the first top support frame 211 and is used to connect the first top support frame 211 and the second top support frame 212.

A drive rod 430 is fixedly installed on the first top support frame 211, and its telescopic end is fixedly connected to the feeding plate 420. During operation, the telescopic movement of the drive rod 430 causes a variable gap to form between the feeding plate 420 and the fixed plate 410. Under gravity, the pipe falls step-by-step through the feeding chute 411, achieving automated feeding. Specifically, when the drive rod 430 telescopically extends, it causes the feeding plate 420 to slide up and down, cooperating with the fixed plate 410 to feed the pipes one by one. When the drive rod 430 extends, the feeding plate 420 rises, lifting the pipe and causing it to slide into the feeding chute 411 of the fixed plate 410.
