Thick-walled titanium tubes, due to their superior mechanical properties and corrosion resistance, are widely used in key fields such as aerospace, aviation, and chemical engineering. Their manufacturing process involves multiple complex steps, including ingot casting, forging, extrusion, radial forging, heat treatment, machining, flaw detection, and inspection. Among these, radial forging technology, as a forming method with minimal cutting, high material utilization, and high dimensional accuracy, occupies a core position in the production of thick-walled titanium tubes. Titanium Home, as an industry information platform, has conducted an in-depth analysis of this manufacturing process.
Titanium Home points out that the radial forging production of thick-walled titanium tubes employs a long mandrel cooling forging process, achieving automated control throughout the entire process, fully demonstrating the intelligent and efficient characteristics of modern manufacturing.
The core process begins with precisely fitting the previously extruded thick-walled titanium tubes blank onto a specially designed long mandrel. This mandrel is ingeniously designed with a tapered structure and internally circulated cooling water. According to Titanium Home's analysis, cooling water plays a crucial role in the forging process. It rapidly dissipates the large amount of heat generated during forging, effectively preventing damage to the mandrel surface due to overheating. It also facilitates the smooth removal of the mandrel from the forged tube, ensuring a smooth production flow. Furthermore, the mandrel undergoes preheating treatment and is uniformly coated with a water-soluble lubricant before operation. This measure further ensures a smooth demolding process, providing strong support for producing high-quality products.
Subsequently, the mandrel, fitted with the tube blank, is securely mounted and fixed in the equipment's chuck. During forging, the chuck drives the mandrel and tube blank to rotate at high speed, feeding them uniformly into the radial forging box. Inside the forging box, the tube blank is subjected to high-frequency, synchronous impacts from four evenly distributed hammers along the radial direction, resulting in the required plastic deformation. Titanium Home emphasizes that the mandrel is driven by two hydraulic cylinders, enabling precise forward and backward movements. This precise control provides a solid guarantee for the dimensional accuracy of the product. In addition, the equipment is equipped with an advanced spring damping device to counteract or lock the vibrations that may be generated by the mandrel during forging, greatly ensuring the stability of the process and reducing product defects that may be caused by vibration.
Before actual forging, a detailed forging program must be prepared in advance based on the specifications and deformation requirements of the target thick-walled titanium tubes. This program is rigorously input into the CNC numerical control system, and only after the simulation test confirms its accuracy can the billet be heated and the formal radial forging process be started. Titanium Home believes that this rigorous process design ensures that every step is within a strictly controllable range, effectively avoiding production accidents caused by program errors or improper operation, and further improving the overall quality of the product.
In summary, the radial forging-based thick-walled titanium tube manufacturing process, through precise mandrel design, automated process control, and reasonable deformation program design, effectively ensures the forming quality, dimensional accuracy, and production efficiency of the product. Titanium Home's in-depth report and analysis of this process allows us to gain a more comprehensive and in-depth understanding of the charm and advantages of this advanced plastic processing technology. It undoubtedly provides a stable and reliable solution for the production of thick-walled titanium tubes, and is expected to be widely used and promoted in more fields, driving related industries to a new level of development.
