    摘要: A method of shaping the external surface of a metal billet which comprises holding the billet stationary and moving a pair of grooved rolls which are idly rotatably supported over the billet so that the billet passes through a gap between the rolls and guiding the paths of the rolls to provide the billet with the required shape. This method is preferably carried out by apparatus which comprises a pair of grooved rolls which are idly rotatably supported with a gap between them, means for holding the billet stationary, a mechanism for moving the rolls to cause them to pass along a billet held by the holder so that the billet passes through the gap between the rolls, and at least one guide track for each roll for guiding the path of the roll as it is moved by the mechanism. Preferably each grooved roll is supported on a shaft which extends axially beyond the ends of the roll and two runner rolls, each of which runs along a guide track as the grooved roll is moved, are mounted on the ends of the shaft. The guide tracks of the two rolls are preferably movable relatively to each other to adjust the paths of the grooved rolls and thus adjust the shape to which the billet is shaped.

    摘要: A drawing die includes an outer steel ring having an axial opening having three different diameters therethrough providing first and second shoulders therebetween. A cylindrical recess is provided by the maximum diameter portion of the opening for receiving a plurality of inner and outer segments arranged in matching sets. At least one wedge receiving slot is provided in each set of inner and outer segments and a wedge in each slot is adapted to bear against the first shoulder. A working bushing having an inner diameter less than the minimum diameter of the axial opening and an outer diameter substantially equal to the intermediate diameter of the axial opening bears against the second shoulder. The wedges are movable axially to force the segments of each set apart to firmly hold the bushing in place.

    摘要: Fluid-pressure operable segments surrounding rod-deforming die are controlled by wire-diameter sensing device. As die wear occurs, sensing device responds to increased wire diameter and raises fluid pressure to advance segments inwardly against die thereby to constrict die and decrease diameter of die orifice.

    摘要: An adjustable die for drawing polygonal tube, rod, bar, or the like having a casing with a polygonal recess therein, a plurality of adjusting wedges arranged one to each side of the polygonal recess, and a plurality of die blocks having a principal angle equal to the principal angle of the polygon and a forming surface disposed substantially perpendicularly to the bisection of the principal angle of the draw block. Each block is disposed in the recess to be primarily supported by an adjusting wedge, and the wedge and block assembly is disposed against a backing plate to be axially supported against the forces of drawing.
