Dragging presently remains one of basic methods of production of continuous types of simple form.
Advantages of this method before other processes of deformation consist the in a presence worked
and serially let out technological equipment, to relative simplicity of technological process, stability
of sizes of good on length after dragging. At the same time, creation of saveresources`s technologies
is an actual task.

Positive results are given by the technology of dragging, based on realization of the mode of
hydrodynamic friction. An unsolved task here is creation of terms, providing the stable mode of
hydrodynamic friction, which allows to promote firmness volok, to lower expenditures on electric
power, to obtain the even distributing of temperature on the section of wire and multiply productivity
by reduction of losses of time on replacement of the instrument worn out.

Are presently developed row of devices and methods for realization of terms of hydrodynamic friction.
So, the pressurized chamber with the two voloks, in space between which and accordingly in the hearth
of deformation greasing is given Milliken M. P. is offered under constraint. The given construction
does not provide reliable pressurization of working chamber, that multiplies the expense of greasing.
In addition, in a number of cases, for example at the serve of wire with a povishenoy roughness, the
mode of hydrodynamic friction can be violated.

The indicated failing was partly removed in the Taratuti K.V. construction, where compaction`s
voloka executes the function of piston and provides festering of greasing in a working chamber.
However the process of serve of greasing is here provided in the impulsive mode, that the smooth
increase or reduction of pressure of greasing on the entrance in the hearth of deformation at the
increase or reduction according to the roughness of initial purveyance does not enable to carry out.

Pressure under which the technological greasing is given in working voloka in indicated higher
processes must be sufficient for providing of screening layer dividing the surface of metal and
instrument. For this purpose the thickness of layer of greasing must exceed the total height of
roughnesses of metal and instrument. Because the roughness of metal in the process of dragging
can change, for example increase, the screening layer of greasing in this case must be multiplied.
On the decision of the given task and offered in the real work technology of dragging and
construction of the combined team is directed voloka for its realization.

The offered device on the picture 1 is collapsible construction consisting of corps 1, sealing 2,
pressure 3 and working 4 voloks, parted by the springs 13 and 14. Pressure voloka 3 and working
voloka 4 are inserted in containers 6 and 7 and fastened by the fixednesses 11. In the container 6
opening are foreseen 9 for overflow of greasing. Nut 10, is screwed on on a corps 1, what the
cone-shaped container 7 fixs sealing voloka 2. In the corps 1 opening are foreseen, with the set in
them valves 8. A corps is fastened on a wire-drawing figure by means timber the screw-bolts 15.

The device works as follows. A wire is skipped through sealing, pressure and working voloks,
disconnected by the springs 13 and 14. By the nut 10 smooth regulation of initial pressure of
springs is provided on working one I voloku. Working chamber 12 through the valves 8 and 9 is
filled by greasing under permanent, counted on the minimum roughness of wire by pressure which
the terms of hydrodynamic friction will be provided at. At this roughness the container 6 with
forcing voloka 3 will be found in the extreme left position, not recovering, however, opening
with the valve 8. At the increase of roughness of surface of wire and as a result – rise of
coefficient of friction in sealing voloka, the container 6 will begin to squeeze a spring and
moving on motion of dragging will be instrumental in festering of greasing in working voloka 4
multiplying the layer of greasing between surfaces voloka wire. The same the adequate serve of
greasing depending on current status of surface of wire is achieved. At a roughness equal maximal
pressure voloka will attain extreme right position, but as in the case of minimum roughness, will
not block opening with the valve 9. At reduction of roughness of wire container 6 with voloka 3
will move to initial position, and the surplus of greasing from the left part of working chamber
will overflow in right, on opening 9. Container 6 with opening 9 acts part of shock absorber and
is instrumental in smooth motion of forcing voloka 3 in both the directions. Application of
containers with the prepared outward surfaces providing their sliding on the internal surface of
corps, allows to use already existent complete sets voloks.

The thus offered technology of dragging and construction of the combined team voloks provide
the smooth change of pressure of greasing on the entrance in the hearth of deformation of
working voloks at the change of roughness of wire and accordingly smooth adjusting of thickness
of screening layer of greasing for providing of the stable mode of hydrodynamic friction.
