The invention relates to the field of metal and can be used in engineering and other industries.

A known method of manufacturing parts by stamping materials using magnetic-pulse treatment of a metal workpiece (SU 758623, B 21 D 22/74), where the workpiece material is deformed by the interaction of the magnetic fields arising when connecting the magnetic coil to the generator named the config as a prototype method, in which the workpiece is deformed by the movement of the transmission medium, which affect power pulses adapter, roaming, for example, the electromagnetic field of the inductor (SU 3279228, B 21 D 26/14, 1998). The disadvantage of this method is that when deep stamping parts of complex configuration may cause bumps leading to marriage.

The problem on which this invention is directed, is to reduce the complexity of the tooling and improving the quality of manufactured products.

This goal is achieved by the fact that in the known method of manufacturing parts by stamping materials, which consists in the fact that the workpiece is deformed by the movement of the transmission medium, which affect power pulses adapter, roaming, for example, the electromagnetic field of the inductor, medium expel from the Central zone of the workpiece to its periphery by introducing into the medium a shaped solid body affected by moving the adapter, with the material transmission medium pre-enclosed in a thin elastic shell.

The drawing shows one of the practical options proposed with field results in movement of the adapter 2. Moving the adapter 2 dispersed shaped solid body 3, which is implemented in medium 4 so that displace it from the Central zone of the workpiece 5 to the periphery. At the same time Vistanova necessary detail and looks the part material, shaping its final form by the matrix 6. The matrix 6 is fixed to the housing 7 by means of screws 8, and the environment limit from the extrusion zone of the workpiece using a restrictive bushing 9.

Example. For experimental verification were made pipes of aluminium alloys, of a thickness of 0.1 - 1 mm Movement of the adapter affecting the environment, was carried out by using a flat coil, powered by magnetic pulse generators with stored energy discharge from 1 to 5 kJ.

The nozzles had a variable cross-section, the transition areas to ensure the rigidity of the parts in the radial direction of the planned local protrusions and depressions.

Nevertheless manufactured using the proposed method the details of the shape and dimensions comply with the drawings. This matrix was used simplified in construction and, therefore, cheaper.

Thus, the th production of tooling and virtually eliminate the occurrence of defective products due to the directional displacement of environment, which smoothes the workpiece and eliminates the education is not provided documentation dents, protrusions, bumps and other defects.

1. A method of manufacturing parts by stamping materials, which consists in the fact that the workpiece is deformed by means of a transmission medium, which affect power pulses adapter, roaming, for example, the electromagnetic field of the inductor, wherein the medium expel from the Central zone of the workpiece to its periphery by introducing into the medium a shaped solid that is dispersed by the adapter.

2. The method according to p. 1, characterized in that the material of the transmission medium pre-enclosed in a thin elastic shell.
