Abstract
A method for manufacturing a forged component includes: performing hot forging on a material; heating the hot forged material to a first set temperature; and performing warm coining to correctly shape the heated material. The material may be heated to a second set temperature before hot forging. The material heated to the second set temperature may be hot forged. The second set temperature may be higher than the first set temperature. The hot forged material may be subjected to controlled cooling to a third set temperature at a predetermined cooling rate. The controlled cooled material may be heated to the first set temperature. The third set temperature may be lower than or equal to the first set temperature.
Claims7
A method for manufacturing a forged component, the method comprising:
- heating a material to a second set temperature;
- performing hot forging on the material after heating the material;
- cooling the hot forged material to a third set temperature at a predetermined cooling rate after performing hot forging on the material;
- reheating the hot forged material to a first set temperature after cooling the hot forged material;
- and
- performing warm coining to correctly shape the reheated material after reheating the cooled material,
- wherein the third set temperature is lower than or equal to the first set temperature.
