FOUR-STRIKER FORGING MACHINE Russian patent published in 2004 - IPC

FIELD: plastic working of metals, possibly forging ingots and billets in hydraulic forging presses and radial-squeezing machines.

SUBSTANCE: two holders of upper and lower strikers and two holders of lateral strikers have respective inclined surfaces and they are kinematically coupled one with other by means of eight guides having П-shaped cross section. Each guide is fixed at one side on lateral surface of holder of upper or lower striker. At other side of guide its inclined surface is in sliding contact with inclined surface of holder of lateral striker. Strikers are secured to holders. Inclined surfaces of guides are arranged by inclination angle 0-75 degrees relative to inclined surfaces of holders of strikers. Holder of lower striker includes lengthwise grooves. In lower part of holders of lateral strikers scrapers or brushes are mounted. Working surfaces of scrapers or brushes rest upon sliding surfaces of holder of lower striker.

EFFECT: improved design, elimination of jamming of lateral striker holders in guides, prevention of scale penetration on sliding surfaces.
