AI Technical Summary
In the existing cold heading process, the thread strength of the bolt is not high, or even incomplete. The thread groove of the forming mold cavity hinders the deformation of the rod body, resulting in incomplete processing.
Bolt processing equipment, including blanking components, blank preparation components and forming components, is used to form an elliptical cylinder and threaded groove through multiple cold forging processes. The second stamping die is used to push the die to perform forward stamping on the rod, so that the material is embedded in the threaded groove to form a tight connection.
It improves the strength and precision of the bolt thread, solves the problem of incomplete thread, and ensures the high strength and precise forming of the bolt.
