Description
(54) УСТРОЙСТВО ДЛЯ ОГРАНИЧЕНИЯ КРИВИЗНЫ ТРУБ ПРИ ВОЛОЧЕНИИ(54) DEVICE FOR RESTRICTING PIPE CURVATURE DURING TRIMMING
основна деформаци , в результате которой труба 18 приобретает круглое сечение заданных размеров. В момент начала волочени включаетс электродвигатель 7, который приводит во вращение вал 3. Вращательное движение вала 3 с помощью шатуна 5 преобразуетс в качательное движение волокодержател 9. Таким образом, труба 18 в волоке 10 подвергаетс дополнительно знакопеременному кручению, причем передача крут щего момента трубе 18 обеспечиваетс благодар наличию щпонки 19 и выполнению волоки 10 с каналом некруглой формы.the main deformation, as a result of which the pipe 18 acquires a circular cross section of a given size. At the beginning of the drawing, the electric motor 7 is turned on, which drives the shaft 3 to rotate. The rotational movement of the shaft 3 by means of the connecting rod 5 is converted into the swinging movement of the fiber holder 9. Thus, the tube 18 in the die 10 is subjected to alternating alternating torsion, and torque transmission to the tube 18 This is ensured by the presence of a pin 19 and the execution of a die 10 with a channel of non-circular shape.
Дл получени оптимальных результатов необходимо производить настройку устройства в зависимости от размеров и материала прот гиваемых труб, величин деформации и скорости волочени . Регулируемые параметры: частота качаний волокодержател 9 и угол его поворота.In order to obtain optimal results, it is necessary to adjust the device depending on the size and material of the pipes being drawn, the values of deformation and the speed of drawing. Adjustable parameters: frequency of oscillations of fiber hanger 9 and its angle of rotation.
Частота качаний регулируетс путем изменени числа оборотов электродвигатеЛЯ 7. Величина угла новорота регулируетс винтом 17.The frequency of oscillations is adjusted by changing the number of revolutions of the electric motor 7. The magnitude of the angle of rotation is controlled by the screw 17.
Устройство позвол ет уменьщить кривизну прот гиваемых труб.The device makes it possible to reduce the curvature of the drawn pipes.
