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, transition simplicity from one size of type on other, enough
high performance and comparatively low cost of unit of instrument. However and is here present row
of tasks requiring the decision, namely abbreviation of number of transitions, rise of firmness of
wire-drawing instrument, decline of expense of metal, electric power materials and other.

The row of directions of rise of efficiency of process of dragging is known:
voloks application of vibrations or the metal stretched out, the use antitension of metal, creation
in the hearth of deformation of hydrodynamic terms of friction due to application of the special
constructions of wire-drawing instrument.

Actuality of the given work consists in the theoretical ground technological parameters of process
of dragging from a antitension of wire in the conditions of hydrodynamic friction in the hearth of
deformation, and also perfection of construction of wire-drawing instrument, that will allow in
eventual result to lower the prime price of the metal stretched out and promote him quality.

Purpose and tasks of work:
Development of scientific bases of improvement and mastering of technology of dragging from a
antitension of wire, and also development of constructions for creation antitension of wire and
wire-drawing instrument providing hydrodynamic terms of friction in the hearth of deformation.
For achievement the put purpose must decide next tasks:
1. To develop methods and devices providing the conduct of process of dragging from a antitension
of wire.
2. To perfect a wire-drawing instrument in the direction of rise of pressure greasing in a deformation
area with the purpose of creation of hydrodynamic terms of friction.
3. To explore influencing of deformation parameters and antitension of wire on tension of dragging
and coefficient of friction. To perfect a method experimental determination of coefficient of friction.

Research object:
Process of dragging with a antitension of wire.

The article of research:
Theoretical and practical ground of parameters of technology and equipment providing the conduct
of process of dragging in the conditions of hydrodynamic one frictions in the hearth of deformation.
Design of process of dragging of provodilost by a software product "Ansys".
