    摘要： A process for drawing stretched metal workpieces, especially tubes, for the purpose of cross-sectional reduction in more than one drawing step using at least two sequential drawing aggregates. The aggregates grip the workpiece on the outer periphery, with two alternately-moved clamping carriages, which draw the workpiece continuously through respective drawing rings associated with the respective aggregates and arranged in respective drawing-ring holders. The drawing aggregates can be driven independently of one another in a power-regulated and/or moment-regulated manner. Furthermore, during the drawing process, a defined prestress force, which prevents deflection of the workpieces from a straight line, is maintained at all times in the section of the workpiece located between the drawing aggregates.

    摘要： A single carriage of the drawing apparatus for pulling a continuous metal workpiece through a drawing die is displaceable back and forth by a linear electronic motor drive. A coil forms a supply upstream of the die which can pay off a length of the workpiece to form a loop adapted to be drawn through the die without tensioning it against the coil.

    摘要： An apparatus for reforming rod-shaped, electrically conductive and/or magnetizable materials, in particular for drawing and extruding, having the following features: the apparatus has a female mold having a die, which forms the tool for reforming; the apparatus has an inductor of an electric linear motor, by means of which a traveling electric field can be produced; the inductor includes at least one first group at least with first coils; the first coils in the first group are arranged axially next to one another and thus form a channel; using the inductor it is possible to produce a traveling field in the channel which has a magnetic flux density having a gradient in the axial direction of the channel, which has an amplitude of greater than B=1 T.

    摘要： Method of straight-line drawing for reducing the cross section of round material, tubing, solid and hollow profiles in at least two drawing stages, which includes feeding material to be drawn with a leading end to a first drawing machine for a first drawing stage, feeding the material to be drawn with the leading end in a straight line downstream of the first drawing machine. Subsequently the material to be drawn is fed with the leading end to at least one second drawing machine having a linearly movable intermittently operable drawing carriage operating at a discontinuous speed at the beginning of the drawing while said first drawing machine is already operating continuously, being disposed downstream of the straight line for at least one second drawing stage. Next, the material to be drawn from the straight line upstream of the second drawing machine is deflected as soon as the leading end of the material to be drawn has reached the second drawing machine, and the length of the deflected material is varied for equalizing differences in feeding speed between said first and second machine.
