摘要： A method of making a steel core brass stair rod includes placing a brass billet into a chamber of an extrusion apparatus, where the brass billet includes an aperture configured to receive a steel core. The brass billet is heated to a temperature at which the brass billet is pliable. The brass billet and the steel core are co-extruded through a die of the extrusion apparatus such that the brass billet forms a brass shell which is fused to the steel core, where there is no air gap between the brass shell and the steel core.

摘要： A method for forming a lightweight axle shaft is provided. A first tubular blank is inserted in a die defining an extrusion throat at one end. A tool is inserted into the die having a mandrel with portions of increasing diameter. The tool is moved towards the outlet end of the die to partially extrude the blank through the extrusion throat and form a hollow axle shaft having a variable inner diameter based on the varying diameter of the mandrel. The tool is then removed and a second tubular blank is inserted and placed in engagement with the first blank. The tool, or a different tool, is inserted into the die and again moved towards the outlet end of the die to complete extrusion of the first blank and produce a shaft having diameters at each end that are less than the diameter of an intermediate portion of the shaft.

A chuck is mounted on the frame for holding one end of a wire, and a drawing die is mounted on the carriage for passing the wire therethrough. An actuating device is connected to the carriage for moving it along the frame to move the die along the wire so as to reduce the cross-section of the wire. A plurality of clamp devices are mounted on the frame and spaced along the length thereof for holding the wire. A plurality of drive devices are operatively connected respectively to the clamp devices to move them into and out of an operative position in a path of travel of the carriage where the clamp devices engage the wire. A plurality of position sensors are operatively connected respectively to the drive devices and sense the approaching of the carriage toward the respective clamp devices disposed adjacent thereto to produce a sensing signal in response to which each drive devices is operated to move the clamp device associated therewith out of its operative position.
