СПОСОБ ПРОИЗВОДСТВА КАЛИБРОВАННЫХ ПРУТКОВMETHOD OF MANUFACTURE OF CALIBRATED BARS

1one

Изобретение относитс  к волочильному производству.FIELD: dragging.

Известен способ производства калиброванных прутков с предварительной запрессовкой переднего конца заготовки без его предварительного острени  в волоку с последующим волочением заготовки.A known method for the production of calibrated rods with pre-pressing the front end of the workpiece without first pre-cutting it into the fiber and then dragging the workpiece.

Однако при запрессовке прутков (особенно малых диаметров, менее 18 мм) передний конец заготовки изгибаетс  и захват его зажимными губками каретки затрудн етс . Кроме того, искривленные концы приходитс  отрезать на большую длину.However, when pressing in the bars (especially small diameters, less than 18 mm), the front end of the workpiece is bent and its gripping by the clamping jaws of the carriage is difficult. In addition, the curved ends have to be cut to a greater length.

Целью изобретени   вл етс  увеличение производительности процесса и уменьшение отходов металла. Это достигаетс  тем, что по мере выхода переднего конца прутка из волоки при запрессовке перед волочением осуш,ествл ют его правку.The aim of the invention is to increase the productivity of the process and reduce the waste of the metal. This is achieved by the fact that as the front end of the die goes out during pressing, before straining it drains, it is edited.

Конец прутка 1 (см. чертеж) запрессовываетс  в волоку 2, установленную в доске волок 3. Одновременно с этим опускаетс  ползун 4, в который вставлен вал 5 с закрепленным в нем полукольцом 6, которое обхватывает конец прутка, выход щий из волоки.The end of the bar 1 (see drawing) is pressed into the fiber 2 installed in the board of the fiber 3. At the same time, the slider 4 is lowered into which the shaft 5 is inserted with the semi-ring 6 fixed in it, which embraces the end of the rod coming out of the dies.

Враща  вал 5 с помощью гидроцилиндра с зубчатыми передачами на один оборот попеременпо в противоположных направлени х, прав т конец прутка полукольцом 6, изгибающим его в различных направлени х.Rotating the shaft 5 by means of a hydraulic cylinder with gears for one turn alternately in opposite directions, the end of the rod is right by a semi-ring 6, bending it in different directions.

За врем  запрессовки вал 5 делает два - три цикла движений, после чего он останавливаетс  прорезью полукольца 6 вниз, ползун 4 поднимаетс , освобожда  место дл  каретки волочильного стана. Затем процесс повтор етс .During the pressing, the shaft 5 makes two to three cycles of movements, after which it stops by cutting the half ring 6 down, the slider 4 rises, making room for the drawing mill carriage. The process then repeats.

Предмет изобретени Subject invention

Способ производства калиброванных прутков , включающий запрессовку прутка в волоку волочильного стана и волочение, отличающийс  тем, что, с целью повыщени  производительности процесса и уменьщени  отходов, по мере выхода переднего конца прутка из волоки при запрессовке перед волочением осуществл ют его правку.A method of producing calibrated rods, which includes pressing a rod into the drawing of a drawing mill and drawing, characterized in that, in order to increase the productivity of the process and reduce waste, as the front end of the wire exits from drawing during pressing, it is straightened before drawing.
