Description
в процессе изгиба труб (фиг. 3) иопорачиваетс рама станка, при лтом ложемент 11 посредством прижимного 12 и обкатывающего 13 роликов поворачиваетс отиосгггельно ролика 8 и обкатывает трубу, укладыва ее в pyieii 9 ро.чика 8. Калибрующа оиравка поворачиваетс вместе с рамой станка вокруг ролика и постепенио выходит из деформированного конца трубы . Деформаци (изгиб) труб происходит по узкой кольцевой зоне с всесторонним обжатием деформируемой зоны труб посредством ролика, ложемента, оправки. Экономический эффект от внедрени предлагаемой оправки составит около 1 тыс. руб., суммарный экономический эффект на предпри ти х отрасли составит около 4 тыс. руб. Ф о |) м у л а и 3 о б ) е т е н и Оправка трубогибочиого стайка, содержаща дорн, св занный с держателем, отличающа с тем, что, с целью обеспечени гибки труб, вставленных одна в другую с зазором , она снабжена обоймами, расположенными концентрично дорна и с возможностью регулировочного перемещени относительно него.in the process of pipe bending (Fig. 3), the machine frame is turned, with the clamping bed 11 by means of the clamping 12 and the rolling rollers 13, the roller 8 is rotated with the aid of the bolt and the pipe is rolled in pyieii 9 of the roller 8. The calibration tool rotates with the machine frame around roller and gradually comes out of the deformed end of the pipe. The deformation (bending) of the pipes occurs along a narrow annular zone with a comprehensive compression of the deformable zone of the pipes by means of a roller, a cradle, a mandrel. The economic effect from the introduction of the proposed mandrel will be about 1 thousand rubles, the total economic effect on the enterprises of the industry will be about 4 thousand rubles. F o |) m u l a and 3 o b) e te n and a mandrel of a pipe bending bead, containing a mandrel associated with a holder, characterized in that, in order to ensure the bending of the pipes inserted one into another with a gap, provided with holders located concentric with mandrel and with the possibility of adjusting movement relative to it.
