Изобретение относитс к области обработки металлов давлением, а именно к процессу резки труб кручением, и может быть применено в заготовительных цехах машиностроительных заводов.The invention relates to the field of metal forming, in particular, to the process of cutting pipes by torsion, and can be applied in the processing shops of machine-building plants.
Известен способ резки труб, включающий зажим трубы и отрезаемой заготовки и прилол :ение крут щего момента к отрезаемой заготовке 1.A known method of cutting pipes includes clamping a pipe and a cut piece and prilol: torque is applied to cut piece 1.
Однако при этом способе затруднена передача крут щего момента при отрезке от трубы коротких заготовок, так как происходит проскальзывание и нарушаетс процесс резки , а потому качество среза получаетс недостаточно высоким.However, this method makes it difficult to transfer the torque when cutting short pipes from the pipe, since slippage occurs and the cutting process is disturbed, and therefore the cut quality is not sufficiently high.
Цель изобретени - повыщение качества разрезаемых поверхностей.The purpose of the invention is to increase the quality of the cut surfaces.
Цель достигаетс тем, что крут щий момент прикладывают как к наружной, так и к внутренней поверхност м отрезаемой заготовки.The goal is achieved by applying a torque to both the outer and the inner surfaces of the cut piece.
На фиг. 1 дана схема резки; на фиг. 2 - разрез по А-А на фиг. 1.FIG. 1 given cutting scheme; in fig. 2 is a section along A-A in FIG. one.
Осуществл ют предлагаемый способ следующим образом.Carry out the proposed method as follows.
На трубу 1 выдавливанием или механическим путем нанос т кольцевую канавку 2 наAn annular groove 2 is applied to the pipe 1 by extrusion or mechanically.
наружной поверхности и канавку 3 на внутренней поверхности. В трубу 1 ввод т поддерлсивающую оправку 4. Трубу 1 зажимают снаружи секци ми зажима 5 и 6, а внутри - секци ми зажима 7.the outer surface and the groove 3 on the inner surface. A supporting mandrel 4 is inserted into the pipe 1. The pipe 1 is clamped outside with clamp sections 5 and 6, and inside with clamp sections 7.
Затем к наружной и внутренней поверхност м трубы через секции зажима 5-7 передают крут щий момент. Секцию зажима 5 вращают в противоположном направлении по отношению к секци м зажима 6 и 7. Крут щий момент прикладывают до отделени от трубы 1 заготовки 8.Then, a torque is transmitted to the outer and inner surfaces of the pipe through the clamp sections 5-7. The clamp section 5 is rotated in the opposite direction with respect to the clamp sections 6 and 7. A torque is applied prior to the separation of the pipe 1 from the blank 8.
