Description
два участка: участок 4 предварительрюй калибровки и участок 5 окончательной калибровки.two sections: section 4, preliminary calibration and section 5 of the final calibration.
.Между йнструменталт помещают заготовку. Основани 1 перемещают навстречу друг другу. Формующие клинь 2 внедр ютс в заготовку, вызыва ее вращение. Боковыми наклонными гран ми 3 избытки металла перемещаютс .по направлению к торцам. Оставша с между инструментами часть металла предварительно калибруетс участком 4 инструмента, образующим микронеровности на прокатываемой поверхности заготовки. В процессе окончательной калибровки участком 5 инструмента деформаци металла локализуетс в поверхностном слое, при этом происходит интенсивна деформадн микронеровностей, способствующа увеличению чистоты поверхности.. Between the tool place the workpiece. The bases 1 move towards each other. Forming wedges 2 are inserted into the workpiece, causing it to rotate. With side oblique faces 3, the excess metal moves towards the ends. The remaining part of the metal between the tools is pre-calibrated by the tool section 4, which forms microscopic irregularities on the rolled surface of the workpiece. In the process of final calibration by the instrument section 5, the deformation of the metal is localized in the surface layer, and an intense deformation of the asperities takes place, contributing to an increase in the surface cleanliness.
Интенсивность деформации и ее локальность- завис т от размеров микронеровностей: при большой величине микронеровностей деформаци не лока-: лизуетс в поверхностном слое, при малой величине снижаетс интенсивность деформации. :The intensity of deformation and its locality depend on the size of asperities: with a large value of asperities, the deformation is not localized: it is located in the surface layer, and at a small value the intensity of deformation decreases. :
Экспериментально установлено, что эффект повышени чистоты поверхности изделий про вл етс предварительной калибровкой инструмента с чистотой поверхности от Rj 80 до R 320.It has been established experimentally that the effect of increasing the purity of the surface of the products is a preliminary calibration of the instrument with a surface purity of Rj 80 to R 320.
Так при прокатке заготовки из стали 4 диаметром 20 мм,, нагретой до liob С, инструментом с параметрами р 6°20, jL 30, а также чистотой поверхности участка предварительной калибровки R.j; 160, участка окончательной калибровки 1,25 получена чистота поверхности издели 2,5. В то же врем при известном способе с аналогичными параметрами, но безSo when rolling a billet of steel 4 with a diameter of 20 mm, heated to liob C, a tool with parameters p 6 ° 20, jL 30, and the surface cleanness of the preliminary calibration section R.j; 160, final calibration section 1.25, the product surface finish is 2.5. At the same time, with the known method with similar parameters, but without
предварительной калибровки достига80 .preliminary calibration is reached80.

Предлагаемое изобретение позвол ет исключить операцию чистового точени высоким экономическим эффектом только от снижени производственной заработной платы.The present invention eliminates the finishing operation with a high economic effect only from lowering production wages.
