ABSTRACT:
A press for producing machine elements, such as balls, rivets and the like, especially machine elements of relatively small dimensions, e.g. balls having a diameter of 1 mm, from wire sections, which includes a wire intake device, a device for shearing off the wire, a device for conveying the wire sections to and in front of a stationary matrix, and a punch associated with the matrix and adapted to be reciprocated back and forth in axial direction with regard to the matrix. If desired, there may also be provided ejectors for the punch or the matrix. The punch is, axially with regard to the matrix, movably guided in a tool carrier which in pressing direction is stationarily arranged in the machine frame. Furthermore, the punch is drivingly connected to a rotatable cam disc through the intervention of a pick-up roller.
