Description

Technical Field

[0001] This invention relates to the field of riser processing equipment technology, specifically an eight-station riser processing unit. Background Technology

[0002] As a key pressure-bearing component in fields such as petrochemicals, building water supply and drainage, and marine engineering, the structural integrity, dimensional accuracy, and connection reliability of risers directly affect the operational safety and service life of the entire system. With the development of industrial equipment towards larger scale, higher pressure, and greater integration, more stringent requirements are being placed on the processing quality (such as wall thickness uniformity, end face flatness, thread accuracy, and weld joint strength) and production efficiency of risers. Currently, the processing flow of risers typically includes multiple core processes such as pipe cutting, end face turning, inner and outer wall polishing, thread processing, weld beveling preparation, flange assembly, sealing testing, and marking. The existing processing methods mainly suffer from the following technical defects: The fragmented processing steps result in low production efficiency: Traditional riser processing often employs single-station, independent equipment for step-by-step operations. This means that the pipe material needs to be transferred, positioned, and clamped multiple times between different machines such as cutting machines, lathes, polishing machines, threading machines, and beveling machines. This model not only increases auxiliary operation time but also makes it difficult to coordinate the production rhythm between different machines, resulting in low overall processing efficiency and an inability to meet the needs of large-scale production. Especially for risers with large length-to-diameter ratios and heavy weights, the transfer process also poses safety hazards.

[0003] Low level of automation and reliance on manual operation: In the existing processing flow, many steps such as material transfer, clamping and adjustment, process switching, and quality inspection rely on manual labor. This not only results in high labor intensity and labor costs, but also makes it easy for human error to affect the stability of processing quality. At the same time, manual operation makes it difficult to achieve real-time optimization and closed-loop control of processing parameters, and cannot meet the requirements of high-precision and high-consistency processing.

[0004] Existing riser processing technology suffers from numerous problems, including fragmented processes, low efficiency, poor precision, low automation, and limited adaptability, making it difficult to meet the modern industrial demand for high precision, high efficiency, high flexibility, and low cost in riser processing.

A vertical pipe clamping mechanism is installed on the outer periphery of the top of the processing rotating table. A processing unit is fixedly installed on the top of the processing machine table. The processing unit is located outside the processing rotating table. The output of the processing unit is in contact with the vertical pipe clamping mechanism. The number of processing units is eight. The eight processing units are distributed at equal intervals on the outside of the processing rotary table. The eight processing units are divided into four different processing units, with each pair of processing units corresponding to the other. The number of pipe clamping mechanisms is also eight. The eight pipe clamping mechanisms correspond to the eight processing units, and the eight pipe clamping mechanisms have the same structure.

[0007] The selected support feet consist of nine sets, which are distributed at the bottom of the eight-station riser processing unit in a manner of three sets each on the length, width, and diagonal.

[0008] Specifically, the eight-station riser processing unit has a preset platform on the right side, a test power source is installed on the top of the preset platform, and a riser clamping device is installed on the top of the preset platform, with the riser clamping device located to the right of the test power source.

[0009] The selected eight processing units are each equipped with a different motor, and the output end of each processing unit is provided with a different processing end, which includes turning, drilling, threading and polishing.

Simultaneously, the coordinated control of each workstation ensures synchronized production cycles. Especially for risers with large length-to-diameter ratios and heavy weights, this not only avoids safety hazards during transfers but also increases overall processing efficiency by more than 50% compared to traditional decentralized processing, meeting the needs of large-scale production.

[0016] 2. Multiple processes completed in a single clamping, ensuring machining accuracy and component quality: This invention adopts an overall positioning datum design, allowing the riser to complete all machining processes in a single clamping, effectively eliminating the cumulative errors caused by positioning errors and datum inconsistencies resulting from traditional multiple clamping. Through coordinated precision control at each station, surface damage to the riser caused by multiple clamping is avoided, significantly enhancing the component's pressure-bearing capacity and corrosion resistance, and reducing risks in later use.

[0017] 3.

Through a PLC control system, it achieves fully automated or minimally automated operation, significantly reducing labor intensity and costs. Simultaneously, automated control avoids human error and enables real-time optimization and closed-loop control of processing parameters, ensuring the consistency and stability of batch-processed product quality and meeting the requirements for high-precision and high-consistency processing.

It achieves the goals of high precision, high efficiency, high flexibility, and low cost in riser processing, providing a reliable riser processing solution for fields such as petrochemicals, building water supply and drainage, and marine engineering.
