The present invention also discloses a force increasing self-locking drill chuck with said self-locking mechanism. The self-locking mechanism according to the present invention can be used in drill chucks of multiple structures, and provides a brand-new thought for the designs of the self-locking mechanisms of drill chucks.

An axial force control nut assembly 10 includes a seat member 11, a fastening nut 12 rotatable relative to the seat member and a ring assembly 13 disposed between the seat member and the fastening nut. The ring assembly 13 can include one or more rings. At least one of the rings is an axial force control ring 20 is freely rotatable before a bolt axial force reaches the proper axial force and is restricted in rotation after the bolt axial force is equal to or greater than proper axial force. Alternatively or in addition, the ring assembly 13 can include an elastic deformation ring 21. A gap is defined between a radially outer portion of the elastic deformation ring 21 and the seat member 11 before the bolt axial force reaches the proper axial force. The gap between the radially outer portion of the elastic deformation ring 21 and the seat member 11 becomes zero after the bolt axial force is equal to or greater than the proper axial force.

The invention discloses a roll-forming method of a TC17 titanium alloy complex deformed section ring unit. The method is used for rolling of complex deformed section ring units which are complete in appearance, high in accuracy of size, excellent in structure and performance, and distributed along the outline of a part. According to the technical scheme, TC17 titanium alloy bars blanked by specification are heated and then treated with jumping-up, punching and twice small deformation ring rolling to form rectangular pre-rolled compact, heated rectangular pre-rolled compact is rolled in a pre-rolled section groove by a pre-rolled inner pattern module and a pre-rolled outer pattern module to form deformed pre-rolled compact which is in a structural shape contrary to that of the finally rolled deformed section ring unit, and heated deformed pre-rolled compact is rolled in a finally rolled section groove by a finally rolled inner pattern module and a finally rolled outer pattern module to form the deformed section ring unit. During the rolling, the deformed pre-rolled compact widens along the radial direction in the finally rolled section groove and metal inside flows from places with more metal to places with less metal according to a predetermined volume flow rate. The ring unit is mainly used for revolving body components like a cylindrical shell used in fields like aerospace.
