Application Cases of Automatic Pipe Cutting and Deburring Production Line
Case in the Automotive Manufacturing Industry
In the current booming development of new - energy vehicles, a well - known new - energy vehicle manufacturing enterprise has an extremely large and stringent demand for various metal pipes in its production process. From the frame structure that supports the entire vehicle architecture, to the brake system pipelines that are crucial for driving safety, and then to the battery cooling system pipelines that ensure the stable performance of batteries, every part relies on high - precision pipe components. To break through the bottleneck of the traditional processing mode, the enterprise resolutely introduced an advanced automatic pipe cutting and deburring production line, and since then, the production process has undergone a comprehensive and in - depth optimization.
Innovation in Pipe Processing for Frame Structure
As the "skeleton" of new - energy vehicles, the frame structure needs to have high strength and a complex shape design to meet the safety and performance requirements of vehicles under different working conditions. The automatic pipe cutting and deburring production line adopted by this enterprise has demonstrated excellent capabilities in the pipe processing link of the frame structure. Facing high - strength alloy pipes of different specifications, the automatic pipe cutting machine operates in an orderly manner based on preset procedures, relying on cutting - edge numerical control technology. Its built - in high - precision sensors and intelligent control system work closely together to monitor key parameters such as the position, speed, and cutting force of the pipes in real - time during the cutting process, ensuring that the pipes are precisely cut into the exact lengths required by the frame design. The length error is firmly controlled within a very small range, just like a precision craftsman in the millimeter - scale world, without the slightest deviation.
After the cutting is completed, the automatic deburring machine quickly "takes over". It is equipped with a variety of special grinding tools for different materials and pipe diameters. Using advanced image recognition technology, it accurately locates the sharp burrs generated at the cut ends of the pipes. While the grinding tools are rotating at high speed, they intelligently adjust the grinding force and angle according to the material characteristics of the pipes and the burr conditions, just like experienced craftsmen carefully carving. They quickly and thoroughly remove the burrs. This process not only ensures the safety of workers in the subsequent welding and assembly processes, avoiding work - related injuries caused by burr scratches, but also plays a key role in improving the welding quality. The smooth and burr - free pipe ends make the welds more uniform and firm during welding, greatly enhancing the overall stability of the frame structure and laying a solid foundation for the safe driving of new - energy vehicles on complex road conditions.
Upgrading of Brake System Pipeline Processing
As the "blood vessels" of the brake system of new - energy vehicles, the brake system pipelines have almost stringent requirements for the inner wall smoothness and pipe diameter accuracy of the pipes. The slightest defect may lead to serious problems such as brake fluid leakage and unstable brake pressure, directly endangering driving safety. The automatic pipe cutting and deburring production line has played an important role in this critical field with its intelligent control technology.
When cutting the pipes used in the brake system, the automatic pipe cutting machine precisely adjusts the cutting parameters according to the material and diameter of the pipes and the design standards of the brake system. For example, for high - strength stainless - steel brake pipeline pipes, the equipment optimizes parameters such as cutting speed, tool feed rate, and cutting temperature to ensure that the cut is flat and smooth without deformation, cracks, or other defects. Subsequently, the automatic deburring machine adopts a unique flexible grinding technology for the particularity of the inner wall of the brake pipeline pipes. The grinding tools, through a special mechanical structure, penetrate deep into the pipes. Without damaging the inner wall of the pipes, they efficiently remove the tiny burrs and impurities generated by cutting, making the smoothness of the inner wall of the pipes reach an extremely high standard. At the same time, the production line uses a high - precision pipe diameter measuring instrument to detect the pipe diameter of the cut pipes in real - time. Once it is found that the pipe diameter deviation exceeds the allowable range of the design, it immediately automatically adjusts the cutting and deburring process parameters to ensure that the pipe diameter of each brake system pipeline fully complies with the design standard.
Taking the production of the brake system pipelines of this enterprise as an example, before the introduction of the automatic pipe cutting and deburring production line, due to the difficulty of manual processing in precisely controlling the burrs and size deviations at the pipe ends, some pipelines leaked during strict pressure tests, and the product defective rate was as high as 10%. After the introduction of the production line, the defective rate was significantly reduced to less than 2%. This remarkable achievement not only greatly improves the product quality, reduces the waste of raw materials caused by defective products, but also significantly increases the production efficiency, saving the enterprise a large amount of time and labor costs for rework, and effectively promoting the efficient and high - quality development of the enterprise's brake system pipeline production.
Optimization of Battery Cooling System Pipeline Processing
The battery cooling system pipelines are crucial for maintaining the stable working temperature of the batteries in new - energy vehicles, extending the battery life, and ensuring battery performance. Different battery cooling methods, such as liquid cooling and direct cooling, have different but equally strict requirements for the processing accuracy and surface quality of the pipes.
In terms of the processing of liquid - cooled system pipelines, the automatic pipe cutting machine accurately cuts the length of the pipes according to the complex routing and connection requirements of the liquid - cooled system pipelines and ensures that the cut angles are precise, so as to achieve seamless connection with components such as cooling plates and joints in the subsequent process. The automatic deburring machine focuses on fine - grinding the inner and outer walls of the pipes. While removing burrs, it ensures the smoothness of the inner wall of the pipes, reducing the resistance of the coolant flowing in the pipes and improving the cooling efficiency. For direct - cooled system pipelines, due to their extremely high requirements for the sealing and surface finish of the pipes, the automatic pipe cutting and deburring production line adopts a more precise cutting and grinding process. The automatic pipe cutting machine ensures that the cut is flat and free of micro - defects by optimizing the cutting path and tool selection. The automatic deburring machine uses advanced electrochemical grinding technology to polish the surface of the pipes, making the surface of the pipes reach a mirror - like finish, effectively avoiding the leakage risk of the refrigerant flowing in the pipes due to uneven surfaces.
After the introduction of the automatic pipe cutting and deburring production line, the processing quality of the battery cooling system pipelines of this enterprise has been significantly improved. The battery cooling effect is more stable and reliable, and the performance and life of the batteries are effectively guaranteed. The production efficiency has also been greatly increased, enabling the enterprise to better meet the growing market demand for new - energy vehicles and winning a key advantage for the enterprise in the fierce competition in the new - energy vehicle market.
