Description

Известны способы гибки трубок, при которых трубки помещаютс  между желобчатым роликом и двум  желобчатыми поворотными матрицами .Methods are known for bending tubes, in which tubes are placed between a grooved roller and two grooved swivel matrices.

При таких способах гибки получаютс  гофры в тонкостенных трубках , загибаемых с малым радиусом.With such methods, bends are obtained corrugations in thin-walled tubes, bent with a small radius.

В отличие от известного предлагаетс  способ гибки трубок, в котором , с целью повышени  качества гибки, матрицы в процессе гибки перемещаютс  вдоль оси трубки таким образом, что изгибаема  трубка находитс  все врем  в кольцевом окружении, образованном из желобов ролика и матриц.In contrast to the known, a method of tube bending is proposed, in which, in order to improve the quality of bending, the matrices in the bending process move along the tube axis so that the bend tube is always in an annular environment formed from roll troughs and matrices.

На чертеже изображена схема гибки трубок предлол енным способом .The drawing shows a diagram of the bending of tubes in a pre-folded manner.

Трубка / закладываетс  в желоб ролика 2   с другой стороны прижимаетс  двум  полуматрицами 3 и 4. Полуматрицы вращаютс  вокруг оси 5 ролика 2 таким образом, что вокруг подлежащей изгибу трубки образуетс  кольцевое окружение 6, исключающее возможность образовани  гофра.The tube / is laid in the groove of the roller 2 on the other hand is pressed by two semi-matrixes 3 and 4. The semi-matrixes rotate around the axis 5 of the roller 2 in such a way that around the tube to be bent an annular environment 6 is formed, excluding the possibility of corrugation.

Кольцевое окружение 6 образуетс  из желоба ролика и желоба в матрицах, которые вместе дают кольцо. Причем дл  сохранени  кольцевого окружени  в процессе гибки, матрицы все врем  перемещаютс  по ходу гибки, чтобы не разорвать кольцо.The annular environment 6 is formed from a roller groove and a groove in the dies, which together form a ring. Moreover, in order to preserve the ring environment in the process of bending, the dies move all the time along the bend in order not to break the ring.

Описанный способ гибки тонкостенных трубок, примененный на одном из автозаводов, дает возможность значительно улучшить гибку трубок и качество выпускаемых изделий. В насто щий момент установка, служаща  дл  осуществлени  предлагаемого способа, налажена на производство гибки п ти наименований трубок; заказанные дополнительные установки позвол т перевести значительное количество трубок на гибку по предлагаемому способу.The described method of bending thin-walled tubes, applied at one of the car factories, makes it possible to significantly improve the bending of tubes and the quality of the products. At present, the installation serving for the implementation of the proposed method has been established for the production of five types of tubes; ordered additional installations will allow a significant number of tubes to be bend using the proposed method.
