Title:
スクラップ剪断機
Document Type and Number:
Japanese Patent JP4484961
Kind Code:
B2
Abstract:
A scrap shearing machine comprising a straight-blade shear-stand (20), an open-wide feed channel (30), a side hydraulic ram (63) for squashing a metal scrap (35) sideways in the feed channel, and a feeder (40) for feeding the squashed metal scrap into the mouth of the shear-stand. In order to squash a long-rigid metal scrap by relatively small drive force, the side ram (63) is adapted to squash the scrap sideways only at a certain limited section which is shorter than the overall length of the scrap in the longitudinal direction of the feed channel (30). A downward hydraulic ram (53) is associated with the side ram (63) and is adapted to downwardly squash the scrap (35) only at the limited section prior to squashing operation of the side ram (63). A control unit (70) is associated with the respective drive systems of the shear-stand (20), of the feeder (40), of the side ram (63), and of the downward ram (53), for supervising and controlling them in a predetermined operation sequence.
