Zusammenfassung:The utility model discloses an upsetting tool for an ultrahigh-diameter-ratio large alloy steel ingot free forging press, a longitudinal through hole is arranged in the middle of the upsetting tool, a hoisting counter bore is arranged at the upper part of the outer wall of the upsetting tool, the longitudinal through hole is divided into three sections, namely a first cone frustum at the bottom, a second cone frustum in the middle and a horn-mouth-shaped arc-shaped ring surface platform at the upper part, and the first cone frustum and the second cone frustum are cone frustum-shaped. The upsetting die is used in cooperation with a large alloy steel ingot free forging press with the ultrahigh diameter ratio, the problems that a round steel ingot blank with the height-diameter ratio larger than 4.0 is unstable or cracks are generated and a high-alloy steel ingot is segregated in the upsetting process are solved, and the mechanical property and isotropy of a forged piece are remarkably improved. 本实用新型公开了一种超高径比大型
