Tube end forming equipment industry observation: automation, intelligence and flexible production has become the mainstream of development

In recent years, with the continuous acceleration of the pace of transformation and upgrading of China's manufacturing industry, as a pipe end forming equipment for pipe fitting processing basic equipment, it is experiencing a profound technological change. From traditional models that rely on manual operation to intelligent equipment equipped with CNC systems and automatic loading and unloading, the main theme of the development of the industry has become clear - automation, intelligence and flexible production are becoming the mainstream direction of pipe end forming equipment.

  Pipe end forming equipment is the core equipment for deep processing of pipes. Through shrinkage, expansion, pier head, rounding, flanging and other forming processes on the ends of pipes, it meets the requirements of connection, sealing and assembly between pipes, and is widely used in building water supply and drainage, fire protection, HVAC, refrigeration, automobiles, hydraulics and other fields. It can be said that all industries involving metal pipeline connections are inseparable from the support of the pipe end forming process. The scale and prosperity of the downstream industry directly determine the market space and technological evolution direction of pipe end forming equipment.

  Automation is the most intuitive change in this round of industry upgrades. With the rising labor costs in the manufacturing industry and the shortage of front-line skilled workers becoming more and more prominent, the demand for "machine substitution" in downstream pipe fitting processing enterprises is becoming more and more urgent. The integrated application of functions such as automatic feeding, automatic positioning, automatic delivery, and automatic unloading enables an operator to take care of multiple devices at the same time, which not only greatly reduces labor costs, but also makes the production beat more stable and the processing quality more consistent. Automated models such as transmission type and gantry manipulator type have been rapidly popularized in mass production scenarios such as clamping pipe fittings and automobile pipelines.

  Intelligence gives the device a “brain.” The new generation of tube end molding equipment is generally equipped with a touch screen numerical control system to support process parameterized programming and storage calls. The processing parameters of different products can be entered in advance. When switching varieties, one-click calls can be put into production. The fault self-diagnosis function can monitor key indicators such as hydraulic pressure, oil temperature, and stroke in real time. When abnormalities occur, automatic alarms and prompts for troubleshooting direction, greatly reducing downtime and maintenance time. Some high-end models can also be docked with the factory manufacturing execution system to provide real-time data support for production management, so that the equipment status and production capacity can be seen at a glance.

  The construction of flexible production capacity is the key to coping with the "multi-variety, small batch" market norm. The order structure of downstream customers is changing: the proportion of single-variety high-volume orders has declined, while multi-standard and multi-variety orders have become the norm. This requires the equipment to have the ability to quickly change production - the popularity of fast mold structure, so that the mold change time is compressed from several hours to dozens of minutes; a multi-functional composite process integration, so that the shrinkage, expansion, pier head, full circle and other processes are combined on the same equipment as required; double-station, rotary multi-station and other structural designs take into account both efficiency and flexibility, becoming the preferred configuration for medium and large batch and multi-variety production.

  The actual improvement of production switching efficiency is changing the production mode of pipe fitting enterprises. In the past, due to the time-consuming of mold change, enterprises used to centralize the production of orders of the same specifications, and emergency insertion orders often disrupted the overall rhythm. Nowadays, with the help of quick-change molds and one-click calls of parameters, most varieties can be switched within half an hour, and the freedom of production of insertion and merging orders has been significantly improved, and the utilization rate of equipment has increased. The value of flexibility is ultimately directly reflected in delivery commitments and order acceptance capabilities.

  The continuous improvement of accuracy and quality is another main line of competition in the industry. The downstream industry has continuously improved the requirements for pipe consistency and sealing reliability, especially in safety-critical scenarios such as pressure-bearing pipelines and fire protection systems, which has put forward strict standards for pipe nozzle forming accuracy. Equipment manufacturers continue to improve the basic performance of bed rigidity, guiding accuracy, hydraulic stability, etc. The configuration of high rigidity welded bed, precision linear guide rails, hydraulic servo control, etc. is gradually reduced from high-end models to mainstream models, which overall improves the industry's accuracy benchmark.

  In the quality verification process, more and more downstream enterprises have established a full-size inspection system for pipe fittings: the outer diameter of the pier head, the depth of the port, the roundness of the pipe mouth and other key dimensions are reserved according to the batch size, the sealing performance is tested according to the proportion, and the inspection data corresponds to the processing parameters of the equipment one by one. This data-based supply-demand collaboration forces the equipment to maintain stable molding consistency during long-term continuous operation, and also allows highly reliable models to gain higher premium space in the market.

  Green manufacturing ideas are also starting to permeate device design. The application of the energy-saving hydraulic system reduces the energy consumption of the whole machine, the low-noise design improves the workshop working environment, and the optimization of the maintenance convenience of the equipment prolongs the service life and reduces the waste of resources. Although greening is still in its infancy, it has shown a clear trend from "optional configuration" to "standard configuration" and is expected to become an access requirement for developed markets such as Europe in the next few years.

  From the perspective of industrial structure, the rise of domestic pipe end forming equipment is the most important change in the industry in recent years. With the continuous accumulation of technology, domestic equipment has reached the international advanced level in terms of forming accuracy, stability and automation, and has significant advantages in price, delivery time and customized response speed, and the process of import substitution is accelerating. At the same time, the pace of domestic equipment going to sea has accelerated significantly, products are exported to Europe, the Americas, Southeast Asia and other regions, and China-made pipe-end molding equipment is occupying an increasingly important position in the global market.

  At the same time, the synergy between the upstream and downstream of the industrial chain has matured, which has also provided solid support for the upgrading of the whole machine. The core supporting industries such as domestic hydraulic components, linear guide rails, and numerical control systems are becoming more and more perfect. The supply chain response is fast, the customization space is large, and the comprehensive cost is excellent. This enables equipment manufacturers to bring new technologies to the market at a faster iterative speed, and also enables domestic equipment to have a stronger systematic ability in responding to diversified customer needs, forming a benign ecology that promotes the whole machine and supporting each other.

  It is the domestic manufacturers represented by Yanruilin that are the active practitioners of this industry trend. It covers DN12 to DN390 full-specification equipment matrix, covering single-station, double-station, horizontal, vertical, five-row, transmission and other models, and develops special-purpose models for segments such as clamping pipe fittings, fire protection, and automobiles. The capabilities of automation, numerical control, and fast mold change have been applied to a variety of products, providing downstream customers with a wealth of flexible production options. It also confirms the same-frequency resonance between the industry's technical route and the company's product strategy.

  Looking ahead, the pipe end forming equipment industry will continue to evolve in the direction of automation, intelligence and flexibility, and new capabilities such as man-machine collaboration, remote operation and maintenance, and digital process management will gradually become standard. For downstream pipe fitting processing enterprises, when purchasing equipment, in addition to focusing on price and basic parameters, it is necessary to focus on the automation expansion ability, production change efficiency and process flexibility of the equipment to meet the increasingly changing market demand. For equipment manufacturers, only by continuing to be close to the industry process and penetrating into the customer site can they win in the fierce competition and stay steady.
