Description

(54) ПЛАЗМЕННЫЙ РЕЗАК(54) PLASMA CUTTER

Изобретение относитс  к плаэман:но дуговой резке металлов.This invention relates to a plaeman: but arc cutting of metals.

Известен плазменный резак с вихревой подачей плазмообразукнцего газа| содержащий электрододержатель с тугоплавкой вставкой, имегошей тороидальную торцовую поверхность, и сипло с внутренней поверхностью, выполненной в виде конуса, плавно переход щего в цилиндр. Степень обжати  и пространственной стабилизации столба дуги, заключенного внутри. формирук цей камеры , мен етс  в зависимости от эпюры вихревого газового потока, определ емой формой поверхности электрода и сопла и размерами формирующей дугу камеры плазменного резака. Дл  увеличени  ресурса работы электрода и сопла и улучшени  формировани  плазмениой дуги радиус кривизны образующей тороидальной поверхности электрода рагвеи О,5-0,7 диаметра его торца, радиус образующей переходкой поверхности конуса в цилиндр равен высоте цилиндра , а рассто ние по оси резака междуKnown plasma cutter with a vortex flow of plasma gas | containing an electrode holder with a refractory insert having a toroidal end surface, and hoarsely with an inner surface made in the form of a cone, smoothly passing into the cylinder. The degree of compression and spatial stabilization of the arc column enclosed inside. forming the chamber, varies depending on the plots of the vortex gas flow, determined by the shape of the surface of the electrode and the nozzle and the size of the arc-forming chamber of the plasma cutter. To increase the life of the electrode and the nozzle and improve the formation of the plasma arc, the radius of curvature of the torus-shaped electrode surface O, 5–0.7 of the diameter of its end, the radius forming the transition of the cone surface to the cylinder is equal to the height of the cylinder

торцом электрода и торцом сопла равно полутора диаметрам торца электрода. На чертеже схематически изображена формирующа  камера плазменного резака .the end of the electrode and the end of the nozzle is one and a half the diameters of the end of the electrode. Fig. 1 shows schematically a forming chamber of a plasma cutter.

Камера образована поверхност ми электрододержатеп  1 с тугоплавкой вставкой 2 и сопла 3, Кроме того, на чертеже прин ты следующие обозначени :The chamber is formed by electrode-bearing surfaces Step 1 with a refractory insert 2 and nozzle 3. In addition, the following symbols are used in the drawing:

da - диаметр поперечника электрода;da is the diameter of the electrode diameter;

d, - диаметр плоского торца электрода;d, is the diameter of the flat end of the electrode;

RB - радиус плавного перехода от боковой поверхности электрода к его плоскому торцу;RB is the radius of the smooth transition from the side surface of the electrode to its flat end;

$ - величина кольцевого зазора электрод-сопло;$ - the size of the annular gap electrode-nozzle;

dtc - диаметр цилиндрического канала сопла;dtc is the diameter of the cylindrical channel of the nozzle;

RC - радиус плавного перехода от внутренней конической поверхности сопла к его цилиндрическому каналу;RC is the radius of the smooth transition from the inner conical surface of the nozzle to its cylindrical channel;

t - длина цилиндрического канала сопла;t is the length of the cylindrical channel of the nozzle;
