Abstract RU 2501625 C1

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming and can be used at four-hammer forgoing devices of hydraulic forges. Device comprises two holders of top and bottom hammers articulated with side hammer holders by eight lateral pull-away and four centering guides. Centering guides are arranged symmetrically at both sides of the device mirror plane and have axial cavities. Said cavities accommodate compression springs to displace vertically top hammer holder relative to bottom hammer holder. Antifriction plates are mounted at aforesaid inclined surfaces.

EFFECT: higher reliability, longer life, simplified design.
