Съемники 13 снимают готовые издели с оправок 6.FIG. 1 shows the bending device in the initial position; in fig. 2 - the same, after separation by semi-matrices, with departure to the initial position. The pullers 13 remove the finished products from the mandrels 6.

Заходна часть 17 ограничител 8 обеспечивает надежный захват подаваемого материала 7.The entry part 17 of the stopper 8 provides a secure grip on the feed material 7.

Устройство позвол ет изготавливать несколько типоразмеров изделий, дл чего необходимо рассчитать гнезда дл размещени ограничителей и обоймы дл оправок, задаваемых диаметром. Переналадка заклюрезными кромками заготовки; на фиг. 3 - 10 чаетс в замене блока оправок, съемнисечение А-А на фиг. 1 (гибочный узел).The device makes it possible to manufacture several sizes of products, for which it is necessary to calculate the sockets for accommodating the stops and the sleeves for mandrels given by the diameter. Changing the zaklureznymi edges of the workpiece; in fig. 3 to 10 in the replacement of the block of mandrels, the removal of A-A in FIG. 1 (bending unit).

Гибочное устройство содержит ползуны 1 и 2, несущие соответственно полуматрицы 3 первого перехода гибки и полуматрицы 4 второго перехода гибки, установленные на упорах 5 оправки 6. Дл точного направлени подаваемого материала 7, например ленты, предусмотрены ограничители 8, выполненные поворотными, которые утапликов , ползунов с полуматрицами, упоров и ограничителей.The bending device contains sliders 1 and 2, carrying respectively semi-matrix 3 first bending and semi-matrix 4 second bending, mounted on the stops 5 of the mandrel 6. For precise direction of the feed material 7, for example, tapes, limiters 8 are provided, pivoted, which are treads, sliders with semi-matrices, stops and limiters.

Использование одного многопозиционного автомата, имеющего, например, восемь гибочных позиций вместо однопозиционных гибочных автоматов, имеющих равнозначную производительность при изготовлении однотипных деталей, позвол ет заменить линию, состо щую из восьми автоматов, одним, что значительно сокращает парк имеющихс The use of one multi-position automatic machine, which has, for example, eight bending positions instead of single-position automatic bending machines having equivalent performance in the manufacture of similar parts, allows replacing a line consisting of eight automatic machines with one, which significantly reduces the stock of existing

For the spacer, eni-automatic machines, to release up to 70-80% of manufactured products, the clips 10 are installed. The material supply step 7 is limited by the stop 11.

Ползуны 1, оправки 6, ограничители 8, гнезда 9, обоймы 10 и упор 11 смонтированы на монтажной плите 12. Каждый узел гибки, помимо ограничител 8, имеет съемник 13, ось поворота 14 ограничител 8 и поворотный рычаг 15, закрепленный на оси 14 и несущий соединительное звено 16. Ограничитель 8 имеет заходную часть 17 и боковой выступ. Полуматрицы 3 имеют отрезные кромки 18, а полуматрицы 4 - выемки 19 дл захода отогнутых концов.Slides 1, mandrels 6, limiters 8, slots 9, clips 10 and stop 11 are mounted on mounting plate 12. Each unit is flexible, in addition to the limiter 8, has a puller 13, the axis of rotation 14 of the limiter 8 and the swivel lever 15 fixed on the axis 14 and bearing connecting link 16. Limiter 8 has a lead-in part 17 and a lateral protrusion. The semi-matrices 3 have cutting edges 18, and the semi-matrices 4 have recesses 19 for approaching bent ends.

Гибочное устройство работает следующим образом.The bending device operates as follows.

Под действием рычагов 15 ограничители 8 Г-образной формы устанавливают в рабочее положение и устанавливают съемники 13. Ленту подают до упора 11 с одновременной установкой упоров 5. Затем ограничители 8 устанавливают в гнездах 9. Певодственных площадей и использовать их дл других хоз йственных нужд, уменьшить число лиц обслуживающего персонала, а также значительно снизить металлоемкость и расход энергетических ресурсов.Under the action of the levers 15, L-shaped limiters 8 are installed in the working position and pullers 13 are installed. The tape is fed up to the stop 11 with simultaneous installation of the stops 5. Then the limiters 8 are installed in the slots 9. The area and use them for other household needs, reduce the number of persons serving staff, as well as significantly reduce the intensity of metal consumption and the consumption of energy resources.
