Wire drawing apparatus employs a wire take-up device, a rotatable pay-off device and, located therebetween, a rotating wire drawing die. Mounted on the pay-off device is a coil of material from which wire is drawn by the apparatus. This material may be in the form of rod, for example, and, for the sake of simplicity, will be referred to as such hereinafter. The axis of the pay-off device and rod coil thereon, the axis of the take-up device and the wire coil formed thereon and the axis of rotation of the rotating die all are parallel to each other and preferably, but not necessarily, coaxial. A differential speed compensating drive is connected to and drives the pay-off device in the same direction as the die to compensate for the elongation of the rod as it is drawn into wire. The rod is maintained and transferred in substantially the form of a coil between the pay-off device and the take-up device and passes through the die, which rotates in a plane between the pay-off and take-up devices.

In the case of a caterpillar track drawing machine having a drawing die and a caterpillar track disposed behind the drawing die, which track comprises two drawing chains having drawing tools disposed on chain links of the drawing chains, it should be possible to align the drawing tools of at least one of the two drawing chains jointly with the respective chain link, perpendicular to the drawing line, so that the caliber range can be changed, in simple and operationally reliable manner, between two drawing recesses having different caliber ranges. The latter is also possible if two different drawing recesses of the second one of the two drawing chains are intended for a first caliber range for which the first drawing recesses for at least one of the two drawing chains are intended, or if the drawing recesses of a first one of the two drawing chains deviate from the drawing recesses of a second one of the two drawing chains.
摘要:
The invention discloses electric conductor combined by composite conductor and its manufacturing method; the electric conductor forms interface with same or different characteristics among each layer contact surfaces with same or different properties, such as mixture, crystals, alloy, oxysome, etc. When it is electrified, it produces kinds of same or different current effect, such as skin effect, eddy current, ring current, magnetic effect, heat effect, crowding effect, or combined effect which combines each above-mentioned effect; it will play special role and effect if applied on reserved equipment.
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.
