[Scope of utility model registration request]

This is a forging product trimming device for removing burrs from a forged product where a burr is integrally formed around the product part, which is a forged product, and includes a lower die and an upper die that move toward and away from each other under pressure. The lower die has a first part whose upper surface serves as a forged product receiving surface for receiving the product part of the forged product, and which is always urged in an upwardly protruding direction by a first urging member. a receiving member, the upper surface of which is located on the outside of the first receiving member is a cutting edge portion corresponding to the burr portion of the forged product, and is always urged by a second urging member so as to protrude upward; a first deburring member configured such that the cutting edge portion at the protruding position is located below the forged product receiving surface of the first receiving member at the maximum retracted position;
a second receiving member, which is disposed so as to be movable in the vertical direction at a substantially coaxial position with the receiving member, is always urged to protrude downward by a third urging member, and has a lower surface thereof as a forging pressing surface; , the second above
The receiving member is fixedly disposed on the upper mold so as to face the first deburring member at an outer position of the receiving member, and has a lower surface thereof as a cutting edge portion corresponding to the burr portion of the forged product, and the cutting edge portion is connected to the second deburring member. and a second deburring member positioned above the forged product pressing surface when the receiving member is at its maximum protrusion, and the biasing force of each of the biasing members is set such that the biasing force of the first biasing member is the smallest. A trimming device for a forged product, characterized in that the biasing force of the third biasing member is relatively set to be the largest.
