PROCESS FOR INCREASING THE FATIGUE STRENGTH OF COMPONENT PARTS WITH VARIOUS FORMS |
摘要 |
The fatigue strength of high stress areas of components of diverse shapes is increased by cold forming by clamping the component resiliently between a base and a clamp member urged resiliently toward the base, and impacting the component area with a complementary shaped reciprocative snap die driven by a percussion piston. Two diverging dies may be driven by the same percussion piston to impact two spaced component areas such as opposed fillets of a crankshaft throw. |
