In a first embodiment, the bandsaw blade is fed into the workpiece and a continuously operating control motor is used to control a flow valve to alternate the speed at which the bandsaw blade is fed into the workpiece. In a second embodiment, the workpiece is fed into the bandsaw blade and a continuously operating control motor is used to control a flow control valve to alternate the speed at which the workpiece is fed into the bandsaw blade. In a third embodiment, the bandsaw blade is fed into the workpiece and a continuously operating servo motor is used to drive a lead screw to alternate the speed at which the bandsaw blade is fed into the workpiece. In a fourth embodiment, the workpiece is fed into the bandsaw blade and a servo motor is continuously used to drive a lead screw to alternate the speed at which the workpiece is fed into the bandsaw blade.

摘要： A band saw machine which comprises a generally elongated frame structure including an endless band saw trained between and adapted to travel over a pair of spaced guide wheels and having cutting and return reaches therebetween, a positioning mechanism for fixedly supporting a stock to be cut, and a rocking mechanism including a pair of spaced reciprocating drives for rocking the endless band saw through a predetermined angle in the opposite directions generally about the stock to be cut, with the opposite ends of the frame structure alternately upwardly and downwardly shifted. The frame structure is supported for movement relative to the positioning mechanism between inoperative and cutting positions in a direction generally perpendicular to the stock. The rocking mechanism is operable at least during the cutting operation performed by the cutting reach of the endless band saw.

摘要： A severing machine including a feed device for cutting tool arranged to advance continuously to effect cutting of a workpiece, a machine stand with a workpiece supporting table and clamping jaws, and a machine head containing the tool movable relative to the table during cutting. The feed device controls the relative movement of the head in the feed direction and comprises: a ball roller spindle rotatably supported by the stand and provided with outer helical threads, the spindle having a length greater than the maximum feed displacement of the portion of the head in the region of the spindle; two spaced-apart axial bearings carried by the head; a freewheel coupling positioned between the axial bearings and composed of an inner race in threaded engagement with the spindle and having a thread pitch outside of the range of self-locking with the spindle thread, an outer race carried by, and rotatable freely relative to, the inner race, and a coupling mechanism coupling the races together in a manner to permit the outer race to rotate freely relative to the inner race in the direction of rotation of the inner race relative to the spindle during movement of the head in the feed direction, the outer race being driven in that direction of rotation at a rate which is a function of the tool advance; a braked drive motor connected for rotating the spindle; and a unit for adjusting the weight loading by the head on the freewheel coupling.
