    Abstract: A biaxial press molding system includes a cam apparatus having cams facing each other, and a biaxial press apparatus, disposed between the cams and installed to be capable of sliding contacting the cams, for forming a biaxial pressure to a molding object by converting rotational motion of the cams to linear reciprocating motion. Thus, a repulsive force generated during pressing concentrates only on the rotation shaft, so that an optimal design of the frame and a light system are possible. The upper and lower pressure continuously applied to a pressed object can be changed and the maximum pressure can be freely maintained, increased and decreased by forming upper and lower portions at the frictional surfaces of the cams facing each other. Also, a fine control of pressure is possible, the pressure can be appropriately distributed according to part of the pressed object, and mass production of accurate molding products is possible by controlling the pressing point of time.

  • Patent number: 6830442
    Abstract: A rotary table press having a rotatable die table, an upper punch turret and a lower punch turret is provided with a die table that is compartmentalized from the lubricated guides and punch bars to keep dust away from the parts in the die table compartment. Lubrication to the punch bars and guides in the turret is sealed off from the die table compartment. Further improvements pertain to the prior art difficulty with removal and replacement of dies, and removal of the die table. A hydraulic die removal assembly enables the operator to remove the dies, in situ, from the die table. Also, the improved apparatus enables the maintenance worker to pull out the part of the driving shaft that passes through the center of the turrets and die table, then pins are retracted, and with some related adjustments, that enables the die table to be removed from between the turrets. The procedure basically is reversed to re-install the die table.
