Description
(54) УСТРОЙСТВО ДЛЯ РАЗДАЧИ ТРУБ(54) DEVICE FOR DISTRIBUTING PIPES
II
Изобретение относитс к методам изменени диаметра труб обработкой давлением.The invention relates to methods for changing the diameter of pipes by pressure treatment.
Известно устройство дл раздачи труб, со . держащее установленную в корпусе оправку с навитой на нее эластичной трубкой, один конец которой заглушен, а другой соединен с гидросистемой 1.A device for dispensing pipes is known. holding mandrel mounted in the housing with an elastic tube wound on it, one end of which is plugged and the other is connected to the hydraulic system 1.
Однако при раздаче известным устройством на внутренней поверхности труб могут образоватьс выступы в месте контакта трубы с участком сопр жени двух витков эластичной трубки.However, when dispensing with a known device, protrusions may form on the inner surface of the pipes at the point of contact of the pipe with the interface of two turns of the elastic pipe.
Цель изобретени - повышение качества издели путем обеспечени возможности перемещени оправки на половину шага витков .трубки дл повторной раздачи трубы в месте, где имеютс выступы.The purpose of the invention is to improve the quality of the product by allowing the mandrel to be moved by half the pitch of the turns of the tube for re-dispensing the pipe in the place where the projections are located.
Поставленна цель достигаетс тем, что устройство , содержащее установленную в корпусе оправку с навитой на нее эластичной трубкой, один конец которой заглушен, а другой соединен с гидросистемой, снабжено жестко закрепленной в корпусе по оси устроства штангой , на которой подвижно в осевом направ ,лешш смонтирована оправка, и приводом перемещени оправки .The goal is achieved by the fact that the device containing a mandrel mounted in the housing with an elastic tube wound on it, one end of which is plugged and the other connected to the hydraulic system, is equipped with a rod fixedly mounted in the housing axially on which is movable in the axial direction, the shaft is mounted mandrel; and driven displacement mandrel.
При этом привод перемещени оправки может быть вьшолнен в виде жестко св занного с оправкой поршн и размещенного в корпусе цилиндра.In this case, the drive of the movement of the mandrel may be implemented in the form of a piston rigidly connected with the mandrel and a cylinder placed in the housing.
На фиг. 1 показано устройство, продольный разрез; на фиг. 2 - разрез А-А на фиг. 1.FIG. 1 shows a device, a longitudinal section; in fig. 2 shows section A-A in FIG. one.
Устройство состоит из штанги 1, оправки 2, эластичной трубки 3, размещенной на оправке между регулируемыми упорами 4 и 5, полуматриц 6 с механизмом их запирани (не показан). Привод оправки вьшолнен в виде неподвижного цилиндра 7 с порщнем 8, шток которого соединен с оправкой 2. Один конец The device consists of a rod 1, a mandrel 2, an elastic tube 3 placed on a mandrel between adjustable stops 4 and 5, semi-matrix 6 with a mechanism for locking them (not shown). The drive of the mandrel is made in the form of a stationary cylinder 7 with a piston 8, the rod of which is connected to the mandrel 2. One end
15 9 злacти шoй трубки заглушен и подпружинен с оправкой посредством пружины 10, второй 11 - закреплен на оправке и соединен с гидросистемой высокого давлени . Оправка имеет возможность перемещатьс до joiopa 12, а в другую сторону до корпуса 13.15 9 the best of the tube tube is plugged and spring-loaded with the mandrel by means of a spring 10, the second 11 is fixed on the mandrel and connected to a high-pressure hydraulic system. The mandrel has the ability to move up to joiopa 12, and in the other direction to the body 13.
Трубна заготовка 14 установлена неподвижно.Pipe blank 14 is fixed.
