Description

Правка знакопеременным изгибом тонкостенных труб осуществл гтс  обычно вводом е полость выправл емой трубы вращающегос  инструмента , продвигаемого вдоль трубы. Инструменты дл  правки выполн ютс  в виде кулачка или изогнутой штанги. Однако эти инструменты снижают качество правки тонкостенных труб большого диаметра из-за значительного скольжени  трубы но оправке. Кроме того, все известные инструменты подобного рода очень громоздки.Editing with an alternating bending of thin-walled pipes usually involves entering the cavity of the straightened pipe of a rotating instrument that is pushed along the pipe. The straightening tools are in the form of a cam or a bent rod. However, these tools reduce the quality of straightening thin-walled large-diameter pipes due to significant pipe slip on the mandrel. In addition, all known tools of this kind are very cumbersome.

Отличительной особенностью описываемой оп эавки  вл етс  выполпение ее -в виде многоэксцентрикового вала, па эксцентриковых шейках которого посажены ролики, установленные на подшипниках качени .A distinctive feature of the described equipment is its fulfillment in the form of a multi-eccentric shaft, the eccentric shaft of which has rollers mounted on rolling bearings placed on the eccentric shaft.

Такое вьшолненне оправки устран ет скольжение по ней трубы и тем самым позвол ет повысить качество правки труб, особенно тонкостенных большого диаметра.Such a mandrel eliminates slipping of the pipe along it and thus improves the quality of the straightening of pipes, especially thin-walled ones of large diameter.

На чертеже показана в общем виде оправка, введенна  в трубу.The drawing shows in general the mandrel inserted into the pipe.

Оправка выполнена в виде вращаемой и продвигаемой пост пательно по трубе / штанги 2, конец которой жестко св зан с серией валиков 3, 4 и т. -1. с эксцентричными цапфами 5. Кажда  цапфа соединена с носледующим валиком резьбой и стопоритс  винтом 6.The mandrel is designed as a rotatable and push-fit post-pipe / rod 2, the end of which is rigidly connected with a series of rollers 3, 4, and so on. -1. with eccentric trunnions 5. Each trunnion is connected to the shaft with the next roller by a thread and is locked with a screw 6.

На цапфе каждого валика устанавливаетс  подшипник качени  7 и распорные кольца 8. На подшипнике посажена цанга 9 с нарул ньгм конусным по сом, па который надеваетс  ролик 10 с резиновым правпльным бандажом JL Ролик закрепл етс  гайками 12.A roller bearing 7 and spacer rings 8 are mounted on the pin of each roller. A collet 9 is seated on the bearing, and the roller cone 10 with rubber right wheel band JL is attached to the roller cone.

Выправл ема  труба вводитс  в цилиндрическую полость обрезиliCHHoro изнутри желоба 13 п зантемл етс  роликами 10, 14, 15 и т. д,The straightened pipe is introduced into the cylindrical cavity of the cut-off line from the inside of the gutter 13 and is immersed by the rollers 10, 14, 15 and so on,
