Sphere-dynamic nano-resonance materials working method

FIELD: plastic working of materials, possibly cold plastic deforming of parts with predetermined level of operational characteristics.

SUBSTANCE: method comprises steps of placing blank onto support; end upsetting of blank and then deforming it with punch; subjecting punch to complex motion in the form of circular rolling out at simultaneous cyclic axial rocking; subjecting blank at side of its support to cyclic striking pulses acting along helical path. Due to such complex motion of punch blank is deformed by value consisting of 5 - 7 % of predetermined deformation degree. Then motion of cyclic axial rocking of punch is interrupted and pulse effort is applied to punch at frequency equal to that of forced oscillations of support. Blank is subjected to finish shaping by rolling it out with use of punch without pulse efforts. Invention provides wave nature of plastic deformation, penetration of rotor to nano-level of blank material for forming in it massifs of material of "artificial intellect".

The invention relates to the field of materials processing pressure, in particular to methods and devices for cold plastic deformation and details with the specified performance level, and can be used in the manufacture of:

- a new generation of sensors for measuring physical parameters in chemically active environments, ultra-small and ultra-high pressures and at high and cryogenic temperatures;

- new generation of the defining parts of video and audio equipment (switches - magnetically operated contacts)that allows you to create on the basis of one element mutually exclusive physical characteristics: "high elasticity - corrosion resistance - high magnetic induction In5- stable maximum magnetic permeability μmax.

A device that implements the method of Besenova for torsion svetodinamichesky materials processing [1].

The disadvantage of this method is:

- the inability in the process of deformation of the workpiece to ensure penetration of the mechanisms of plasticity (mod rotational ductility) to micro-level with the aim of forming a structural-informational field in the material of the workpiece and its long-term storage in the finished product.

The present invention is to develop a method, which is allows to implement the wave nature of plastic deformation and to ensure penetration of the rotor on nanorover (10 -9m) of the workpiece material and the formation of arrays of material with "artificial intelligence".

The problem is solved in that way svetodinamichesky nonresonance processing of materials is characterized by the fact that it includes placing the workpiece on a support with the possibility of spontaneous cacheline oscillatory movements, mechanical draught of the workpiece and its subsequent deformation of the punch, which reported complex motion in the form of a circular spinning with simultaneous cyclic axial swing when exposed to the workpiece side supports periodic shock pulses in a spiral trajectory, the amount of 5-7% from the predetermined degree of deformation, and then punch relieve traffic cyclic axial swing and make impulsive force with a frequency equal to the frequency of forced oscillations of a support, and then produce the final shape of the workpiece by obkalyvanija its punch when removing impulse force.

The way svetodinamichesky nonresonance materials processing represented by the drawings, there is shown the formation process details at the stage of deformation resonance bearings.

The method is as follows:

The workpiece 6 is set in the cavity of the matrix 2 bearing - svetodinamichesky module 3, the cavity of which is placed p is Senator 4, module 3 is placed on the pusher 5. Then to the workpiece 6 fail obkatkoj punch 1, fixing the workpiece 6 in the cavity of the matrix 2, and produce a regulated end draught of the workpiece 6, after which it is deformed by the punch 1, performing a complicated movement: circular testing with simultaneous cyclic axial swing. Svetodinamichesky module 3 with a certain delay begins reactive to repeat complex movement of the punch 1, objetivas in the same direction and making forced oscillations with frequency ωmdefined damping (dissipation) properties of the workpiece material 6.

When the deformation of the forging of the workpiece 6 on the height of 5-7% from the predetermined degree of deformation energy created conditions for the implementation of the baushinger's effect (DL) [2], which is "remembering" processed material "history" of its loading, i.e. when EB is the energy storage applied to the workpiece 6 during its plastic deformation.

When the deformation of the workpiece 6 in height to a value less than 5% of a given degree of deformation of the energy conditions for the implementation of EB absent, and when the deformation of the workpiece 6 on the value of over 7%, they also do not come.

At this stage of deformation with plug 1 remove the swinging movement, and makes the pulse is violence with frequency ω pequal to the frequency ωmexperimentally defined previously.

After that, the resonator 4 module 3 converts the mode of deformation of the resonance and module 3 produces shock pulse deformation of the workpiece 6 with the resonant frequency of the beating ωR.B.increasing the law of geometrical curve having the shape of a logarithmic spiral [3]. When this is realized the wave nature of plastic deformation and the rotor penetrates nanorover (10-9m) the workpiece material 6 forming in her array of material with "artificial intelligence", i.e. the work is carried out in extreme conditions details of a given program, greatly improving the reliability of the product as a whole.

After a certain time of the processing cycle of the workpiece 6 with plug 1 remove the impulsive force and the finish is shaping parts in the mode of spinning the workpiece 6 by the punch 1.
