Abstract
An elongated piece to be cut is clamped in a vise (9) and is in abutment against a stop (10), the stop (10) being secured on a shaft (11) free to rotate in bearings. The shaft is connected to a connecting rod (19) and a rod (20) of adjustable length to an arm (4) which carries the sawing blade (6), whereby, as the cutting operation is carried out, the stop (10) rises while pivoting and loses contact with the piece being cut before the cutting operation is finished.
Claims20
An apparatus for removing a section cut to length from an elongated piece on a sawing machine comprising
- a saw blade;
- a stand for the saw blade;
- a vise mounted on the stand for holding an elongated piece;
- a movable member displaceably mounted on said stand and carrying the saw blade for performing a cutting operation advancing along a plane disposed perpendicular to the longitudinal axis of the elongated piece held in the vise;
- bearings attached to the stand;
- a frame element in part holding in the bearings;
- a stop movably mounted on the frame element and positioncontrollable on said frame element at a side opposite to the vise relative to a position of the saw blade which pivots with said frame element around an axis of said frame element disposed perpendicular relative to said plane;
- kinematic connection means for tying the movable member carrying the saw blade to the frame element carrying the stop, wherein said kinematic connection means generate a pivoting of said frame element and of the stop progressively starting from an initial position of said stop, wherein the stop is sufficiently removed from its initial position during each cutting operation and before the end of the operation such that the stop no longer remains in contact with any end section being cut and said stop is removed from all contact with the section.
An apparatus for removing a section cut from an elongated piece on a sawing machine comprising a stand (1), a vise (9) mounted on the stand (1) for holding an elongated piece, a movable member (4) diplaceably mounted on said stand (1) for performance of a cutting course in a transverse plane to the longitudinal axis of an elongated piece held in the vise (9), a saw blade (6) mounted on said movable member (4) and driven by a motor, a stop (10) movably mounted on a frame element (15) and position-controllable on said frame element (15) at an opposite side of the vise (9) relative to the saw blade (6), wherein
- bearings (17A, 17B) are attached to the stand (1) and hold said frame element (15) carrying the movable stop (10) for guiding said frame element (15) pivotingly around an axis perpendicular to said transverse plane, wherein
- kinematic connection means (19, 20) connect and tie the movable member (4) carrying the saw blade (6) to the frame element (15) carrying the stop (10), wherein said kinematic connection means (19, 20) generate the pivoting of said frame element (15) and of the stop (10) progressively starting with an initial position of said stop (10), during each cutting operation such that before the end of the operation the stop (10) is sufficiently removed from its initial position in order to be no longer in contact with any section being cut and to disengage the stop (10) from all contact with the section.
