摘要： Continuous extrusion apparatus (FIG. 1) including a rotatable, grooved, wheel 2 is provided with a shoe 6 mounted on a pivot 7 to be rotatable between a position engaging the wheel 2 and a dis-engaged position. The shoe 6 carries a tooling cartridge 10 including an abutment block 14, an expansion block 16, a die block 18 and an exit block 20 connected together with bolts 22 and held in position by locking keys 46 and a retaining ring 50. A reciprocable ram 60 registers with the cartridge 10 when the shoe 6 is in the dis-engaged position and is operable to raise a cartridge 10 from an associated heating chamber 56 into the shoe 6 or to lower a cartridge 10 from the shoe 6 into a storage chamber (not shown). By utilizing a cartridge 10, change-over and pre-heating of sets of dies is facilitated, enabling the apparatus to be connected directly to a continuous casting furnace (not shown).

摘要： Apparatus for the continuous extrusion of metals in which feed is introduced into two (or more) speed apart circumferential grooves in a rotating wheel (or rotating wheels) to contact an arcuate shoe portion and abutments extending into the grooves. The feed is constrained by the abutments to flow through frusto-conical exit apertures of cone angles in the range of 5.degree.-45.degree. in the shoe portion to a chamber which may also be of the divergent frusto-conical form, and is extruded as relatively thin-walled, large-cross-section products. Mixer plates are profiled to distribute flow evenly from the apertures to around the die opening. An extrusion die body for cylindrical extrusions is located and axially centered by set screws. Where an even number of grooves are utilized, an extrusion mandrel may be secured to the shoe portion by a bolt positioned centrally of the grooves and having a passage for injection of lubricant or oxidation inhibiting fluids. Since the volume feed rate is enhanced and the distance travelled by the material from the grooves is reduced, friction losses and the likelihood of discontinuities arising in extrudate products of relatively large hollow cross-section are thereby reduced.

摘要： Transfer means for transferring a continuous elongate product, such as wire, bar or tubular products associated with a continuous extrusion machine, between two stations in the production line. Axial tensioning means 8, 10 each consisting of a pair of resiliently tyred wheels 12, 14 positioned to grip the elongate product 2 and driven by a low inertia, electric, motor induce an axial tension in the elongate product 2. The elongate product forms a curve 20 of catenary form between the axial tensioning means 8, 10. A control signal indicative of the gravitational deflection of the curve is derived from an ultra-light dancer arm 22, or an optical or ultra-sonic sensor, and is utilized in combination with a signal derived from product speed sensor means 24 to control the speed of the low inertia, electric, motors and thus the tension in the elongate product. By providing the axial tensioning means 8, 10 a degree of transient tolerance is obtained between, for example, extrusion speed and spooling speed thereby avoiding axial and radial deformation of the elongate product during transfer along the product line.

摘要： The machine is provided with a set of two pairs of die halves 60, 62 (FIG. 7) mounted in a framework on hydraulically actuated piston and cylinder assemblies. The die halves 60 and 62 of each pair are relatively radially reciprocable to grip or release a workpiece 102, 104 and the two pairs of die halves are relatively axially reciprocable to effect cold pressure welding together of end portions of the workpieces 102, 104. Adjoining end faces of the die halves are formed with nose portions 100 having inner anvil edges for effecting welding flash removal from the workpieces. In operation, the die halves are moved in sequence to grip the workpieces; to urge the ends of the workpieces together to form a cold pressure weld upset zone; to release the workpieces; to grip one of the workpieces; to urge the gripped workpiece axially relative to a pair of anvil edges to clear flash material from the upset to maintain the cross-sectional area at the weld upset zone substantially constant; and to re-position the upset weld zone centrally of the nose portions to repeat the sequence. Removal of the flash material intermediate consecutive weld upsets is effected in alternate directions. The anvil edges may be staggered, angled or of helical form to enhance the shearing effect to clear the flash material from the upset weld zone.
