Description

Technical Field

[0001] This utility model relates to the field of titanium alloy bolt rolling technology, and in particular to a rolling strengthening device for forming titanium alloy bolts. Background Technology

[0002] Titanium alloy bolts are widely used in aerospace, medical devices, and high-end equipment manufacturing due to their superior properties such as high strength, lightweight, and corrosion resistance. However, titanium alloy materials have problems such as a high tendency for work hardening and poor plastic deformation capacity during the forming process. This leads to defects such as microcracks on the thread surface and insufficient fatigue life in traditional roll forming processes. Titanium alloys are extremely sensitive to roll forming parameters, and traditional equipment is difficult to achieve dynamic and high-precision adjustment, which can easily lead to over- or under-pressure, affecting the strengthening effect. Titanium alloys are also prone to adhesion to the roller material, resulting in scratches on the thread surface or material transfer, reducing service performance. Existing roll forming processes are mostly based on empirical parameters and lack precise control over the evolution of the microstructure of titanium alloys, resulting in uneven distribution of residual stress layer. Therefore, we have redesigned a roll forming strengthening device for titanium alloy bolts. Utility Model Content
