These screw presses are specially designed to make bolt head of any kinds of nuts, rivets, motor parts, axle half shaft, engine valve and nonferrous forgings. Vincent presses are screw presses with friction drive on which the forging blow takes place in an upward direction i.e. 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 being moved upwards in axial direction by rotation of longitudinally fixed screw. The bottom die of the forging tools is secured to the lower cross head of the ram while the top die is fitted to a fixed bridge which is the part of the machine frame be employing this design, the forging forces do not act on the machine frame but are sustained by the ram. Ejector is provided at lower part of the ram.
