    摘要: A ram-driven cut-off die set of the double-cut type in which sections of tubing are successively severed from a continuous length of tubing by a notching cut followed by a severing cut wherein improved means are provided for mounting and guiding the notching blade in its notching movement. The improved mounting means comprises an upper shaft positioned over the tube path and extending from one side to the other side of the path, a lower guide shaft positioned totally on the one side of the tube path, and a cross slide having a relatively long upper portion slidably journalled on the upper shaft and a relatively short lower portion journalled on the lower guide shaft to maximize the magnitude of the journalling support provided to the notching blade as it makes its reciprocal movement across the tube path to accomplish the notching cut.

    摘要: Single blade, single cut tubing cut-off apparatus moves a blade along a first path of travel in which a first portion of the blade pierces the tubing and a second path of travel in which a second portion of the blade completes the cut, all in a concerted process. Motion of the blade is controlled by a cam and follower. The tubing is clamped for cutting by a pair of pivotably mounted jaws opened and closed by spring biased cam action.

    摘要: A shearing apparatus for bar stock comprising a fixed die and a movable die wherein the movable die comprises a shearing ring carried by an arm at a location intermediate the ends of the arm, an eccentric fixed on a driven shaft is journalled in one end of the arm, and the other end of the arm includes a slot which receives a rotationally mounted slide block so that the slot and slide block coact to accommodate combined rotary and translatory movement of that end of the arm. The described arrangement produces an elliptical loop movement of the movable die relative to the fixed die to cleanly shear the stock. Also disclosed is a novel mandrel assembly including a pair of plug members adapted to be positioned within tubular stock to be cut wherein one of the plug members is mounted for selective radial excursion during the shearing operation to accommodate the eccentric movement of the movable die.

    摘要: A tubing cutoff die having a horizontally moving scarfing blade and a vertically moving cutoff blade. The tubing being cut off is held in clamping jaws movably mounted on the lower die shoe of the die and actuated by a cam extending from the upper die shoe. The scarfing blade is also mounted for horizontal reciprocation on the lower shoe and actuated by another cam fixed to the upper shoe. The cutoff blade is mounted on the upper die shoe. The two die shoes are reciprocably connected by post and bushing arrangements. There are three of these disposed so that the centerlines are at three of the corners of a rectangle. One of the clamping jaws is mounted on a holder reciprocably mounted on the lower die shoe and the other jaw is mounted on a second holder reciprocably mounted on the first holder. The mounting for the cutoff block provides for either of two rigidly located positions, for different tubing sizes, and the scarfing blade is also adjustable.

    摘要: A double-cut tube cutoff machine for severing steel tubing in such a way as to produce minimum deformation of the tube in the severed area. The machine comprises a base carrying opposing die jaws to clamp the tube, and a ram assembly which moves vertically and reciprocally relative to the base. The ram carries a sharp-pointed severing blade which actually cuts the tubing. A first cam arrangement synchronizes the opening and closing of the die jaws to clamp the tube during a transverse slotting operation as well as during the final severing step. A second cam arrangement synchronizes the motion of a cross slide to ram movement to drive a slotting blade transversely across the tube to notch or slot the top wall part way through prior to the severing operation. The slotting blade is carried in a blade holder which receives inserts of varying thickness so slotting blades of conversely varying thickness all pass over the workpiece in the plane of the severing blade.

    摘要: A press adapted to operate dies such as tubing cutoff dies through a lightweight ram mounted on a parallelogram linkage for oscillating motion rather than for the usual reciprocating motion on a slide. The ram linkage is operated through a crankshaft and connecting rod by a motor, clutch, brake and flywheel. The machine is compact and uses radial bearings rather than slide bearings to guide the ram. The crankshaft and drive mechanism for the ram linkage is conveniently and accessibly located.
