Description
ременную передачу 14 двигателем 15. В средней части водил изготовлены направл ющие 16, Б которых перемещаютс ползушки 17, к которым посредством осей 18 креп тс дорны 19. На направл ющей 16 установлен фиксатор 20, при помощи которого ползущка 17 фиксируетс во врем гибки. Дл подачи заготовки в устройство служит механизм подачи 21, состо щий из рамы 22, на которой установлена плита 23. На гтлите 23 смонтирован пневмоцилиндр 24, щток 25 которого соединен с захватом 26, снабженным опорным роликом 27.a belt drive 14 by a motor 15. In the middle part of the carrier, guides 16 are made, which sliders 17 move to, to which mandrels 19 are fixed by means of axes 18. On guide 16 there is a fixture 20, by means of which the slider 17 is fixed during bending. To feed the workpiece into the device serves as the feed mechanism 21, consisting of a frame 22 on which the plate 23 is mounted. On the plate 23 a pneumatic cylinder 24 is mounted, the brush 25 of which is connected to a gripper 26 equipped with a support roller 27.
На этой же плите 23 смонтированы направл юща 28 дл перемещени захвата 26, снабженного опорным роликом 27, и стойки 29, на которых щарнирно закреплен рычаг 30 с упором 31.On the same plate 23, a guide 28 is mounted to move the grip 26, provided with a support roller 27, and the posts 29, on which the lever 30 is pivotally fixed with an emphasis 31.
Устройство работает следующим образом .The device works as follows.
Механизм подачи заготовки находитс в исходном положении. Рычаг 30 удерживает правый дорн 19 в вертикальном положении . На правый дорн 19 подаетс предварительно нагрета заготовка, включаетс пневматический цилиндр 24 и правый дорн 19 совместно с заготовкой подаетс в гибочное устройство, при этом одновременно с перемещением происходит его поворот на оси 18. Когда правый дорн 19 займет горизонтальное положение, он перестает контактировать с рычагом 30, происходит его перемещение в полость, ограниченную матрицей 1 и гибочными секторами 3, фиксаци ползущки 17 с закрепленным на ней правым дорном 19 фиксатором 20. После этого включаетс двигатель 15, который через приводные валы 11 и шестерни 10 приводит во вращение водила 9 в противоположные направлени .The work feed mechanism is in the initial position. The lever 30 holds the right mandrel 19 in an upright position. A preform is preheated on the right mandrel 19, the pneumatic cylinder 24 is turned on and the right mandrel 19 is fed into the bending device along with the blank, and simultaneously with the movement it rotates on the axis 18. When the right mandrel 19 takes a horizontal position, it stops contacting the lever 30, it moves into the cavity bounded by the matrix 1 and the bending sectors 3, fixing the slider 17 with the right mandrel 19 fixed to it 19. After that, the engine 15 is turned on, which ivodnye shafts 11 and gear 10 rotates carrier 9 in opposite directions.
Смонтированные te нижней части водил 9 гибочные секторы 3 обкатываютс по матрице 1игнут трубную заготовку. При этом дорны 19 синхронно перемещаютс с гибочными секторами 3 и преп тствуют прогибуMounted te on the lower part of the carrier 9 bending sectors 3 roll around the die 1 and the tube billet. In this case, the mandrels 19 synchronously move with the bending sectors 3 and prevent deflection.
стенки получаемого круто изогнутого отвода . После гибки гибочные секторы 3 освобождают отвод, а дорны 19 вывод тс из его внутренней полости, и отвод падает на транспортер. Вкл10чением реверса двигател водила 9 возвращаютс в исходное положение , при этом правый дорн 19 входит в зацепление с захватом 26, расфиксируетс ползушка 17, включаетс пневматический цилиндр 24, и ползущка 17 с правым дорном 19 перемещаетс 6 исходное положение , а дорн 19, взаимодейству с рычагом 30, поворачивает последний, который, в свою очередь, поворачивает дорн 19, устанавлива в вертикальное положение. Затем -цикл повтор етс .walls of a steeply curved outlet. After bending, the bending sectors 3 release the outlet, and the mandrels 19 are withdrawn from its internal cavity, and the outlet falls onto the conveyor. By reversing the engine, the carrier 9 returns to its original position, the right mandrel 19 engages with the gripper 26, the slider 17 unlocks, the pneumatic cylinder 24 is turned on, and the slider 17 moves to the original position 6, and the mandrel 19 interacts with the lever 30, turns the latter, which, in turn, turns the mandrel 19, installed in a vertical position. Then the cycle repeats.
Применение предлагаемого устройства значительно повышает производительность за счет сокращени объема вспомогательных ручных работ.The application of the proposed device significantly improves productivity by reducing the amount of auxiliary handicrafts.

SU424243A1 (en) | INSTALLATION FOR FORMATION OF ELECTRIC MACHINE SHEET PACKAGE1 The invention relates to installations for forming a package of sheets of electric machines from a metal tape. Installations are known for forming a package of sheets of electric machines containing 5 units for punching grooves in a tape moved by the feeder, a bending unit around mandrel and heating device. The punching unit includes preliminary and final groove punching units. Pre-punching in a known dry installation is done with a press, the slider of which is moved by the drive and acts on the moving part of the permanently installed die. 15 The drive for moving the slide is not kinematically associated with the mechanisms for moving the nodes to bend and final punching. An oven for periodic annealing of the tape serves as a heating device.20 The disadvantages of the known installation are the lack of kinematic coupling between the nodes; uneven tape thickness after bending; low productivity due to discontinuous punching and formation of coils; inaccuracy of the inner diameter of the package; the inconvenience of the dimensions of the grooves and schag between them. Increasing the productivity of the process, improving the accuracy of the pitch and shape of the grooves and 30 reducing waste tape are ensured by the fact that the preliminary and final punching of the grooves, the feed mechanism and the bending unit are kinematically connected with the press drive; the preliminary punching unit is made in the form of a multi-seat chip moving back and forth along the front of the press at a speed equal to the speed of the belt moving; the final punching unit is made in the form of a multi-stamp that receives reciprocating movement around the axis of the mandrel and reciprocating movement in the direction of the axis of the mandrel from the press slide through an intermediate element, in particular a drummer located in a sector located coaxially with the mandrel and turned around its axis by means of a turning mechanism, in particular a ratchet containing a separating disc, rigidly connected to the mandrel. The bending unit can be made in the form of one or several pairs of conically rollers and interacting with them segments serving as support for the bend belt mounted in an annular groove of modular guide, n mounted on an outer surface of the transition helical guideway. The assembly guide is aligned with the mandrel. On the mandrel coaxially with her rigidly fixed disk, equipped with | |
