Abstract

PURPOSE:To provide a surplus of pressing force of a die and prolong pressing time of the die by generating deflection deformation in members of a die, a fixed lever and an oscillating lever of a small-sized press. CONSTITUTION:A power gear 4 and an eccentric cylindrical cam 5 are rotated by a prime mover 1 through a reduction gear 2 and a pinion 3. An oscillating lever 8 is in sliding contact with the cam 5 at a power transmitting part 8' and axially connected with fulcrum shafts 11, 11. With the rotation of the cam 5, the power transmitting part 5 moves from the bottom dead center to top dead center and goes up, and before arriving at the top dead center, meshing part 14 of the die 10 comes into close contact, and makes excess movement until it reaches the top dead center. By setting as above, deflection deformation is generated in the members such as the die 10, levers 7, 8 etc.
