Description

В авторском свидетельстве № 23071 описан станок, дл  изгибани  труб, снабженный приводом от гидравлического цилиндра, зажимами дл  конца трубы и поворотным рычагом дл  ее мзгибани .The author's certificate No. 23071 describes a machine for bending pipes, equipped with a drive from a hydraulic cylinder, clamps for the end of a pipe and a rotary lever for its bending.

Насто щее предложение  вл етс  дальнейшим развитием станка и состоит в том, что в трубу, в месте ее изгибани , ввод т укрепленную на станине оправку, котора  предназначена дл  выправлени  складок, образующихс  на изгибе трубы.The present proposal is a further development of the machine tool and consists in the fact that a mandrel fixed to the frame is inserted into the pipe, at the place of its bending, which is designed to straighten the folds formed on the pipe bend.

На чертеже изображено устройство оправки.The drawing shows the device mandrel.

Оправка смонтирована на станине 8 станка и состоит из двух частей: цилиндрической 13 и щарнирно прикрепленной к ней круглой головки 14. В цилиндрическую часть ввернут шток 15, второй конец которого проходит через укрепленный в бетонном фундаменте кронштейн 16 и крепитс  двум  гайками с приваренными руко тками 17. Подлежаща  изгибанию труба вводитс  в обойму 9 с вкладышем 18 и продвигаетс  в ползун 6 с вкладышем 19. К торцу трубы подводитс  упорна  шайба 20, укрепленна  на двух т гах 21, ввернутых в ползун 6. Другой конец т г скрепл етс  направл ющей планкой 22, имеющей посредине отверстие дл  передвижени  по штоку 15 во врем  изгибани  трубы. В т гах 21 имеютс  отверсти  дл  вставлени  двух штырей 23.The mandrel is mounted on the machine bed 8 and consists of two parts: a cylindrical 13 and a circular head 14 hinged to it. Screw the rod 15 into the cylindrical part, the second end of which passes through the bracket 16 fixed to the concrete foundation and fastened with two nuts with welded handles 17 The pipe to be bent is inserted into the sleeve 9 with the insert 18 and advances into the slider 6 with the insert 19. A stop washer 20 is attached to the end of the pipe, fixed on two thrusts 21, screwed into the slider 6. The other end of the clip is fastened strip 22 having a middle hole for moving the stem 15 during bending of the pipe. In the holes 21, there are holes for inserting the two pins 23.

Труба зажимаетс  в ползуне 6, и станок приводитс  в действие, причем труба, проход  через обойму 9, начинает изгибатьс . При выходе из обоймы 9 на трубе получаютс  гофры 24, которые выправл ет кругла  головка 14 оправки 13, введенна  внутрь трубы перед ее изгибанием . Во врем  изгибани  трубы оправка всегда находитс  на одном месте и продвигаетс  вперед по стрелке А лишь когда требуетс  меньший радиус изгиба.The pipe is clamped in the slider 6, and the machine is driven, and the pipe, the passage through the sleeve 9, begins to bend. When exiting the sleeve 9, corrugations 24 are produced on the pipe, which are straightened round the head 14 of the mandrel 13, inserted into the pipe before it is bent. During tube bending, the mandrel is always in the same place and moves forward in arrow A only when a smaller bend radius is required.

Кругла  головка 14 оправки имеет с одной стороны наделку 25, котора  способствует раст гиванню и выправлению лобовой части трубы. %The round head 14 of the mandrel has, on one side, an attachment 25 which contributes to stretching and straightening the frontal part of the pipe. %

Предмет из обретени .The subject of gaining.

В станке дл  изгибани  труб по авт. свил. № 23074 применение оправки 13, снабженной круглой головкой 14, шарнирно скрепленной с оправкой и служащей дл  выправлени  складок на изгибе трубы во врем  ее изгибани  в холодном состо нии без набивки трубы песком к зависимому авторскому свидетельству С. М. Бахтина 87971In a pipe bending machine according to the ed. svil. No. 23074 using a mandrel 13 provided with a round head 14 hinged to a mandrel and used to straighten wrinkles on a pipe bend during its bending in a cold state without sand filling to the dependent author's certificate S.
