Abstract
The sheet cutting die press includes a handle fixed to a cylindrical shaft, the longitudinal axes of which is off-set from the longitudinal axes of stub axles at either end of the shaft. Thus, as the handle is moved causing the shaft to rotate, it applies pressure through a pair of bearings to a pair of pillow blocks which in turn rests on the top surface of a top platen. A cover over the cylindrical shaft is fixed to the pillow blocks so that, as the handle is moved to a position to retract the platen, the pillow blocks are lifted by the cover.
Claims11
A sheet cutting die press including
- an upper platen,
- a lower platen,
- a support member holding the platens in a spaced, generally parallel relationship and permitting the platens to move relatively toward and away from one another, and
- means for moving the upper and lower platens relatively toward and away from one another, one of the upper and lower platens constituting a first platen, the other constituting a second platen, said means including
- a rotatable cam member adjacent to, but spaced from, the first platen,
- a bearing member of a predetermined width received about the cam member, the bearing member including an inner race attached to the cam member,
- a channel block means received between the cam member and the first platen to bear on and slide on the first platen, thereby to drive the first platen toward the second platen as the cam member rotates, the channel block means comprising a channel block having a groove formed therein to receive a portion of the outer race of the bearing member, the groove capturing the channel block between the first platen and the bearing member,
- whereby a sheet cutting die received between the platens may be employed to cut one or more sheets by causing the platens to move relatively towards one another.
