In the aerospace industry at altitudes of tens of thousands of meters, in the deep-sea realm of ocean engineering, and in the precise implant sector of biomedical applications, titanium and titanium alloys have become the preferred materials for critical structural components due to their strong corrosion resistance, high specific strength, and excellent biocompatibility. The internal quality of titanium rings and titanium alloy forged parts directly determines the performance and safety of the final products. Nowadays, the precision forging production process, with its remarkable efficiency and high accuracy, is gradually becoming the mainstream solution for producing titanium and titanium alloy bars.
The precision forging process revolves around the core principle of 'high frequency, small deformation,' achieving comprehensive upgrades from production efficiency and product accuracy to material performance:
1. High-frequency forging with low friction, meeting standards both on the surface and internally: The hammer head can strike hundreds to over a thousand times per minute. The high-frequency impact greatly reduces the friction coefficient between the metal and the tool, not only significantly lowering the surface roughness of the forgings but also making internal deformation more uniform, thus reducing surface cracks caused by friction from the source.
2. Small Deformation, Low Energy Consumption, Win-Win for Molds and Quality: Each stroke is short with minimal deformation, and the contact area between the hammer and the metal is limited. This not only reduces the tonnage and energy consumption required for production, extending the mold's service life, but also prevents internal defects caused by local overloads.
3. Flexible Adaptation, High Precision, Mold-Saving and Worry-Free: The hammer stroke can be flexibly adjusted and, combined with the curved groove design, allows production of forged bars within a certain size range without frequent mold changes. More importantly, the synchronized movement of the four hammers keeps the stroke consistent, ensuring strictly controlled size tolerances of the forgings and providing a stable foundation for subsequent processing.
4. Isothermal Forging, Axial Extension, Say Goodbye to Corner Cracks: By monitoring the billet temperature in real time and precisely adjusting the feed rate, the temperature in the deformation zone is kept uniform, avoiding uneven microstructure caused by temperature gradients. Meanwhile, under the constraint of the curved grooves, the metal extends only axially, completely eliminating circumferential corners and cracks that tend to occur during free forging with flat anvil compression.
5. Triaxial Compressive Stress, High Plasticity, Superior Grain Structure: The triaxial compressive stress generated during forging can increase the metal's plasticity threefold, achieving high deformation ratios of 6:1 for pure titanium and 4:1 for alloys. This effectively refines grains, optimizes internal structure, and enhances the mechanical properties of the forged parts.
