Description
Изобретение относится к заготовительному производству машиностроения, а именно к технологии получения трубных заготовок путем резки труб.The invention relates to the procurement of mechanical engineering, and in particular to a technology for producing pipe blanks by cutting pipes.
Известен способ резки труб, вклю- 5 чающий деформирование трубы в зоне разделения раздачей и приложение сдвигающего усилия разделения [1^].A known method of cutting pipes, including 5, deformation of the pipe in the separation zone by distribution and the application of a shear separation force [1 ^].
Недостаток известного способа состоит в невысоком качестве получае- 10 мых заготовок, обусловленном искажением их торцовых поверхностей.The disadvantage of this method is the low quality of the obtained 10 blanks due to the distortion of their end surfaces.
Целью изобретения является повышение качества резки.The aim of the invention is to improve the quality of cutting.
Поставленная цель достигается тем,15 что раздачу трубы осуществляют с ограничением течения ее материала в радиальном направлении в зоне разделения .This goal is achieved by the fact that the distribution of the pipe is carried out with the restriction of the flow of its material in the radial direction in the separation zone.
На чертеже показана схема проведе- 20 ния процесса резки трубы в штампе.The drawing shows a diagram of the process of cutting a pipe in a stamp.
Трубу при помощи толкателя 1 вводят до упора 2 через неподвижную 3 и подвижную 4 матрицы. Затем посредством формирующей оправки 5 подверга· 25 ют деформированию — раздают в радиальном направлении. Деформирование производят до соприкосновения наружной поверхности трубы с внутренними поверхностями матриц 3 и 4. При этом 30 происходит течение материала трубы в направлении вдоль ее стенок.The pipe with the help of the pusher 1 is introduced all the way through the fixed 3 and the movable 4 matrix. Then, by means of the forming mandrel 5, they are subjected to deformation - they are distributed in the radial direction. The deformation is carried out until the outer surface of the pipe comes into contact with the inner surfaces of the matrices 3 and 4. In this case, the pipe material flows in the direction along its walls.
После этого за счет матрицы 4 осуществляют приложение сдвигающего усилия, в результате чего происходит отделение заготовки от трубы. Упругий элемент 6 штампа возвращает матрицу 4 и оправку 5 в исходное положение.After that, due to the matrix 4, shear is applied, as a result of which the workpiece is separated from the pipe. The elastic element 6 of the stamp returns the matrix 4 and the mandrel 5 to its original position.
В предложенном способе за счет ограничения течения материала трубы в радиальном направлении и за счет соответственно течения материала трубы в направлении вдоль ее стенок возникает растягивающее направление, равное йлй большее предела текучести материала трубы, что обеспечивает получение заготовок без искажения в плоскости разделения, т.е. предложенный способ обеспечивает повышение качества резки.In the proposed method, due to the restriction of the flow of pipe material in the radial direction and due to accordingly the flow of pipe material in the direction along its walls, a tensile direction arises equal to or greater than the yield strength of the pipe material, which ensures the preparation of blanks without distortion in the separation plane, i.e. the proposed method provides improved cutting quality.
