These Screw Presses are specially designed to make bolt heads of any kind of nuts, rivets, motor parts, axle half shaft, engine valve and non ferrous forgings.
Vincent Presses are screw presses with friction drive on which the forging blow takes place in an upward direction, that is, from bottom towards top.
On machines employing the Vincent principle, the screw nut is positioned in the top cross head of a frame type ram. Thus Ram is moved upwards in axial direction by rotation of longitudinally fixed screw.
The bottom die of the forging tools is secured to the lower crosshead of the Ram while the top die is fitted to a fixed bridge which is the part of the machine frame.
The forging forces do not act on the machine frame but are sustained by the Ram.
Ejector is provided at the lower part of the Ram.
