ABSTRACT:
When power failures or breakdowns occur, an apparatus that is able to hold the upper blade in the raised position without using the drive source and increase the safety and facilitate maintenance and inspection.
The work cutting apparatus that cuts by a pair of upper and lower blades is provided with a freely rotating ram mounted with an upper blade, a ram drive device that rotates the ram and an exertion devices that applies a force in the upwards rotation direction to the ram. The rotation center shaft of the ram is positioned at a angle within the horizontal plane with respect to the sides of the pair of upper and lower blades. The exertion devices is positioned such that the horizontal component of that applied force is at right angles to the rotation center shaft. Furthermore, the exertion devices comprises a plurality of coil springs and positions these plural coil springs parallel such that the ends are each aligned with each other along one side of the upper and lower blades.
