Description

Изобретение относится к обработке металлов давлением, предназначено для использования в устройствах для . изготовления деталей U-образной формз! из рулонной стали проталкиванием.The invention relates to the processing of metals by pressure, is intended for use in devices for. manufacturing parts of the U-shaped molds! made of coiled steel by pushing.

В основном авт. св. Ж 935173 описано устройство для изготовления U-образных деталей из рулонного материала проталкиванием. Это устройство содержит смонтированные на станине рулонницу, узел проводки, правильные ролики, механизм подачи, отрезной штамп со смонтированным в отверстии пуансонодержателя поворотным упором и сменную разъемную в плоскости гибки гибочную матрицу, включающую шаблон, смонтированный с возможностью возвратно-поступательного перемещения в направлении подачи ленты и взаимодействующий со средствами удаления детали. Шаблон имеет рабочее отверстие .в _:виде канала, соответствующего про*· филю получаемой детали. Средства удаления готовой детали выполнены в виде установленного в шаблоне подпружиненного выталкивателя, съемника, снабженного приводом возвратнопоступательного перемещения, и толкателя , выполненного за одно целое со съемником и взаимодействующего с выталкивателем. В процессе удаления IQ детали съемник действует на концы ветвей согнутого хомута, а выталкиватель- на центральную его часть, т.е. контакт выталкивающих элементов с деталью осуществляетсятолько по трем точкам, что может вызвать 'перекос и, следовательно, заклинивание детали в шаблоне.Особенно этот недостаток сказывается при удалении хомутов больших размеров или имеющих фа20 сонный профиль.Mostly aut. St. W 935173 describes a device for manufacturing U-shaped parts from roll material by pushing. This device includes a roll mounted on the bed, a wiring unit, straightening rollers, a feed mechanism, a cutting die with a rotary stop mounted in the hole of the punch holder and a removable bending matrix detachable in the bending plane, including a template mounted with the possibility of reciprocating movement in the direction of feed of the tape and interacting with part removal tools. Template has a working hole _.in: a channel corresponding pro * · Fil part to be obtained. Means for removing the finished part are made in the form of a spring-loaded ejector installed in the template, a puller equipped with a reciprocating movement drive, and a pusher made in one piece with the puller and interacting with the ejector. In the process of removing the IQ of the part, the puller acts on the ends of the branches of the bent clamp, and the ejector acts on its central part, i.e. The contact of the pushing elements with the part is carried out only at three points, which can cause a skew and, therefore, jamming of the part in the template. This drawback is especially noticeable when removing large clamps or having a profile profile.

Целью изобретения является улучшение условий удаления деталей.The aim of the invention is to improve the conditions for removing parts.

С этой целью > устройстве для изготовления D-образных деталей гибкой ную матрицу 7 до упора 6. При нажатии ленты на упор 6 подается команда на выключение подачи 4 и привод штампа 5» прорубающего вырезы в на5 чале ленты и на конце согнутой детали 18 и отделяющего ее. После отделения согнутой детали шаблон 9 под воздействием привода 11 перемещается на позицию выталкивания де10 тали. Одновременно поднимается поворотная стенка 10. Срабатывает привод lb. Толкатель 15 воздействует на выталкиватель 14, перемещающий вкладыш 13 вместе с хомутом 18.После вывода хомута за пределы шаблона подается команда на возврат вкладыша в исходное положение. Хомут, распружиниваясь, упирается в торец наружного охватывающего элемента Г2, снимается с вкладыша и падает в тару. Подается команда на возврат шаблона на позицию гибки и опускание поворотной стенки. Цикл повторяется.To this end,> a device for manufacturing D-shaped parts, the flexible matrix 7 to the stop 6. When pressing the tape on the stop 6, a command is given to turn off the feed 4 and drive the stamp 5 ”cutting through the cutouts at the beginning of the tape and at the end of the bent part 18 and separating her. After separation of the bent part, the template 9, under the influence of the actuator 11, moves to the eject position of the part 10. At the same time, the pivot wall 10 rises. The lb drive is activated. The pusher 15 acts on the ejector 14, moving the liner 13 together with the clamp 18. After the output of the clamp outside the template, a command is issued to return the liner to its original position. The collar, springing up, abuts against the end face of the outer female element G2, is removed from the liner and falls into the container. A command is issued to return the template to the bending position and lower the pivot wall. The cycle repeats.

Технико-экономический эффект .предлагаемого устройства определяется улучшением условий его работы за счет повышения надежности работы средств удаления готовой детали.The technical and economic effect of the proposed device is determined by the improvement of its working conditions by increasing the reliability of the means for removing the finished part.

Claims
