FORMING METHOD FOR CYLINDRICAL PRODUCT USING PLATE STOCK BY CASTING PROCESS AND FORMING PRODUCT OBTAINED THROUGH FORMING METHOD OF PLATE STOCK BY CASTING PROCESS

摘要

PROBLEM TO BE SOLVED: To provide a forming method and a forming product obtained by the forming method capable of improving a yield, unit strength, surface- roughness and dimensional accuracy, and forming a cylindrical forming product having a dimensional height which cannot be obtained through a single drawing work by a single drawing, ironing, and compression forming process. SOLUTION: The forming method to product the forming product and the forming product obtained through the forming method by drawing, ironing, and compression forming a raw material composed of metals using a plate stock obtained by the casting or forging process.
