Description

Известно волочение труб в бухтах при помощи самоустанавливающейс  (плавающей) короткой оправки, котора  вводитс  внутрь трубы и благодар  своей форме удерживаетс  в равновесии в очаге деформации . Така  оправка состоит из цилиндрической части, равной внутреннему диаметру трубы иосле волочени  и конической части, меньшее основание которой равно диаметру цилиндрической части и плотно соприкасаетс  с ней, а большее основарше несколько меньше внутреннего диаметра трубы до волочени . Недостатком известной оправки  вл етс  невозможности применени  механизированной шлифовки из-за врезани  шлифовального круга при осевом перемещении в тело оправки.It is known to draw pipes in coils by means of a self-adjusting (floating) short mandrel, which is inserted into the interior of the pipe and, due to its shape, is kept in balance in the deformation zone. Such a mandrel consists of a cylindrical part equal to the inner diameter of the pipe and after the drawing and a conical part, the smaller base of which is equal to the diameter of the cylindrical part and in close contact with it, and the larger base is somewhat smaller than the internal diameter of the pipe before drawing. A disadvantage of the known mandrel is the impossibility of using mechanized grinding due to the embedding of the grinding wheel during axial movement into the body of the mandrel.

Предлагаема  форма самоустанавливающейс  оправки позвол ет примен ть шлифовку на шлифовальных станках, упрошает получение сборных оправок и повышает устойчивость процесса.The proposed shape of the self-aligning mandrel allows grinding on grinding machines, facilitates the production of precast mandrels and improves process stability.

На чертеже изображена схема волочени  трхбы на оправках предлагаемой формы.The drawing shows the scheme of drawing trchby on the mandrel of the proposed form.

Оправки } введены внутрь трубы 2. Волочение производитс  в матрице 3. Оправки J имеют переходную зону между конической и цилиндрической частью либо в виде выемки 4, либо в виде уступа 5, котора  дает выход дл  шлифовального круга при. его осевом перемещении в процессе шлифовани .Mandrels} are inserted into the pipe 2. The drawing is performed in the matrix 3. The mandrels J have a transition zone between the conical and cylindrical part, either in the form of a notch 4 or in the form of a step 5, which provides an outlet for the grinding wheel at. its axial movement during grinding.

Предмет н з о б р е т е н и ;Subject matter of the reference;

1.Самоустанавливаюша с  оправка дл  волочени  груб, отличающа с  тем, что, с целью механизации процесса изготовлени  оправок и упрощени  получени  сборного инструмента, оправка имеет такую форму, при которой очаг деформации трубы, возникающий на конической и цилиндрической част х оправки, сЬстоит из двухотЬ:ельиых очагов, разделенных зоной свободной осадки.1. A self-aligning mandrel for dragging is coarse, characterized in that, in order to mechanize the process of manufacturing mandrels and simplify the production of the assembly tool, the mandrel has such a shape that the deformation area of the tube arising on the conical and cylindrical parts of the mandrel is of two : spruces, separated by a free fall zone.

2.Форма оправки по m 1, отличающа с  тем, что меньшее ч)снование конической частибольше, чем диаметр цилиндрической части и переходит в нее по радиусу или через дополнительный конус.2. The shape of the mandrel is m 1, characterized in that the smaller h is warped with a conical part greater than the diameter of the cylindrical part and passes into it radially or through an additional cone.
