A machine tool with a cam gear for punching and shaping a lead-out of an integrated circuit (machine tool with curved drive, especially for stamping and shaping the connecting pins of integrated circuits)

摘要

The machine tool of the present invention has a frame (10) and a cam gear having two pairs of cam tracks having a complementary cam shape. The tool action is effected by the two levers 3a, 3b hinged to the sides of the clamping blades 8. Each of these levers has two rollers 4a, 6a, 4b, 6b on its one arm and is firmly coupled to a pair of cam tracks. The positions of the different cam tracks are coordinated in a predetermined manner to reduce the frequency of the disturbance oscillation.
