  • Joining of two components in a hot forming process
    Patent number: 7124490
    Abstract: A bushing can be anchored in a sheet steel blank for a cross beam for a vehicle chassis by inserting the bushing into a hole precisely provided in the steel blank, hot forming the steel blank in a die and hardening the hot formed shape steel body in the die. The cooling of the hardening step shrinks the sheet steel into a groove formed in the circumference of the bushing.
