发明名称 DIE FOR FORGING AND METHOD FOR MANUFACTURING THE SAME
摘要 A die for forging and a manufacturing method thereof to reduce manufacturing cost is provided to minimize damage to the whole area of the die by dispersing eccentric load generated in forging into each unit member. A die(100) for forging comprises: a plurality of unit members(110) having one or more holes(112) and having a structure overlapped in a plate shape; and a joint(130) coupled through the hole of the unit member to maintain that a plurality of unit members are coupled. In the unit member, a depression part(111) is formed to bend an object to be forged. The joint comprises: a body inserted into the hole of the unit member; a fixing member(131) including a screw thread formed at both end part of the body; and a connecting member(132) which provides pressure in order that the overlapped unit members adhere closely to each other.
