Zusammenfassung:	The invention discloses a cold forming method for forming power pins and a power pin formed thereof. The cold forming method for forming power pins comprises the following steps: step 1: cutting blank out; step 2: pre-forming the power pin body by necking; step 3: trimming the pre-formed power pin body, and pre-forming a pin fixing disk; step 4: forming the pin fixing disk and a staggered weld leg of pin. The invention also discloses a power pin formed by the cold forming method, composed of a power pin body, a pin fixing disk and a staggered weld leg of pin which are integrally formed into one piece by the cold forming method. The invention achieves high-speed automatic production and high production efficiency with a simple process, and improves material utilization and strength.
