ABSTRACT:
A transverse wedge forming machine is mainly designed for producing (forming) bodies of revolution, such as stepped shafts.
The transverse wedge forming machine of the present invention comprises a housing wherein two parallel plates: a movable and a fixed one, are mounted opposite to each other. The movable plate is mounted in longitudinal slideways of said housing. Each of said plates mounts a composite-in-length wedge-shaped forming tool, the components of each of said forming tools being arranged in a single row in a direction normal to said longitudinal slideways so that the tops of the adajcent components are directed at the opposite sides. The machine comprises also a device adapted for adjusting reciprocating displacement of a part, being formed, from one component of the forming tool disposed on the fixed plate to its next component.
This results in a substantial reduction in the machine length and obviates an inefficient idle stroke of said movable plate, with the ensuing considerable increase in machine production rates.
