Description

1one

Известен способ смазки ири обработке металлов давлением, при котором в качестве смазки примен ют легкоплавкий расплавленный металл.There is a known method of pressure lubrication and metal processing, in which a low-melting molten metal is used as a lubricant.

Однако при этом способе необходимы операции предварительной обработки поверхности деформируемого издели  и нанесени  смазки.However, this method requires pre-treatment of the surface of the deformable product and the application of lubricant.

Предлагаемый способ отличаетс  тем, что поверхностный слой деформируемого металла нагревают в очаге деформации до расплавленного состо ни .The proposed method is characterized in that the surface layer of the deformable metal is heated in the deformation zone to the molten state.

Расплавление поверхностного сло  деформируемого металла можно производить путем нагрева рабочего инструмента, например волоки , токами высокой частоты до темтаературы выше, чем температура плавлени  деформируемого металла.The melting of the surface layer of the deformable metal can be carried out by heating the working tool, for example dies, with high frequency currents up to temperaturaura higher than the melting point of the deformable metal.

Подвод тепла к очагу деформации можно осуществл ть и другими способами.Heat can be applied to the deformation site in other ways.

Мощность теплового потока к поверхности деформируемого металла должна быть подобрана с таким расчетом, чтобы обеспечить расплавление тонкого приконтактного сло  со скоростью, определ емой временем нахождени  металла в очаге деформации.The heat flux rate to the surface of the deformable metal must be chosen so as to ensure the melting of the thin contact layer with a speed determined by the time the metal is in the deformation zone.
