Description

В промышленности известны фильеры, с резко вы.раженным полууглом , например фильеры с углом 5,5° примен ютс  дл  волочени  металлов при всех обжати х, с углом 10° - дл  малых обжатии и 40°- дл  больших обжатий.Dies are known in the industry, with a sharply expressed half-angle, for example, 5.5 ° dies are used for drawing metals during all cuts, with an angle of 10 ° for low compression and 40 ° for large compression.

Особенность геометрии oniscbiBaeмого волочильного канала заключаетс  в том, что длина его рабочего конуса установлена посто нной и равной начальному диаметру подвергающегос  волочению 15здели  (пруток, труба) дл  каждой отдельной операции волочени . Причем оптимальный угол рабочего конуса фильеры определ етс  по формуле:The peculiarity of the oniscbiBae geometry of the drawing channel lies in the fact that the length of its working cone is set constant and equal to the initial diameter of the section to be drawn, 15 sections (bar, tube) for each individual drawing operation. Moreover, the optimum angle of the working cone of the spinneret is determined by the formula:

Формула дает возможность точно определ ть угол рабочего конуса, величина которого находитс  в зависимости от величины частного обжати . Причем длина рабочего конуса фильеры позвол ет легко и точно строить маршруты всл.очени The formula makes it possible to accurately determine the angle of the working cone, the magnitude of which depends on the magnitude of the particular reduction. Moreover, the length of the working cone of the spinneret allows you to easily and accurately build routes all over.

Установленна  длина рабочего конуса, равна  начальному диаметру проволоки, обеспечивает равиомерное распределение напр жений металла при волочении в очаге деформации и относительную равномерность износа по всему маршруту волочильного инструмента .any length. The established length of the working cone, equal to the initial diameter of the wire, ensures the uniform distribution of metal stresses during drawing in the deformation zone and the relative uniformity of wear along the entire route of the drawing tool.

Предмет изобретени Subject invention

Фильера дл  волочени  проволоки , прутков и труб, отличающа с  тем, что, с целью увеличени  стойкости, волочильный канал выполнен по геометрии, в которой длина рабочего конуса равна начальному диаметру проволоки (нрутка, трубы) в каждой отдельной операции волочени , а оптимальный угол рабочего конуса определ етс  по формуле:A die for drawing wire, rods and pipes, characterized in that, in order to increase durability, the drawing channel is made according to a geometry in which the length of the working cone is equal to the initial diameter of the wire (wire, pipe) in each individual drawing operation, and the optimum working angle The cone is determined by the formula:
