Titanium manufacturers in Baoji utilize precision forging machines to produce titanium and titanium alloy bars, which offer high production efficiency, precise dimensions, excellent surface quality, and high material utilization rates. These advantages increasingly highlight the superiority of this method in titanium bar production.
The process characteristics of titanium alloy precision forging are as follows:
① The hammerhead forging frequency is high, reaching hundreds or even thousands of strokes per minute. This loading method reduces the friction coefficient between the metal and the tool, resulting in a smooth surface and uniform internal deformation of the forged part.
② Each stroke of the hammerhead has a small displacement, minimal deformation, and a small contact area with the metal. This significantly reduces deformation force and deformation work, lowering equipment tonnage requirements and extending tool life.
③ The stroke of the hammerhead can be adjusted arbitrarily, and the hammerhead profile offers considerable adaptability to process dimensions. This eliminates the need to change hammerheads, allowing the production of forged bars within a certain size range.
④ During forging, the strokes of the four hammerheads remain unchanged, ensuring high dimensional accuracy.
⑤ The feed rate can be adjusted based on the temperature changes of the billet during deformation, enabling isothermal forging.
⑥ The metal is compressed by four hammerheads with curved grooves, allowing only axial elongation. This prevents circumferential flash and cracks, unlike flat compression in free forging.
⑦ Forging generates high triaxial compressive stresses, which can increase the metal's plasticity by three times and achieve high pass reduction ratios (6:1 for pure titanium and 4:1 for alloys).
⑧ When the feed rate and pass reduction are high, significant thermal effects occur inside the billet, raising the deformation temperature. For example, the temperature rise of TC11 alloy can reach 90°C. Excessive temperature rise may coarsen the microstructure of the forged part.
