Description

Изобретение относитс к обработке металлов давлением, в частности к устройствам формировани пустотелых деталей, типа втулок, гибкой листовых заготовок.The invention relates to the processing of metals by pressure, in particular to devices for forming hollow parts, such as sleeves, flexible sheet blanks.

Известен гибочный узел устройства дл изготовлени пустотелых деталей, типа втулок, из листовых заготовок, содержащий пуансон-оправку, первого перехода гибки и матрицу второго перехода гибки. Пуансон-оправка и матрица первого перехода гибки установлены с возможностью возвратнопоступательного перемещени во взаимно перпендикул рных плоскост х 1.A device for the production of hollow parts, such as sleeves, of sheet blanks is known, which contains a mandrel punch, a first bending transition and a second bending transition matrix. The mandrel-mandrel and the matrix of the first transition are flexible with the possibility of reciprocal movement in mutually perpendicular planes 1.

Недостаток узла заключаетс в возможности прогиба пуансон-оправки на первом переходе гибки при обработке толстолистового материсша, а следовательно , низком качестве получаемых деталей.The lack of a knot lies in the possibility of deflection of the punch mandrel at the first transition, which are flexible when processing thick plate and, consequently, the low quality of the parts produced.

Цель изобретени - повьапение качества деталей при гибка толстолис- товых заготовок за счет исключени прогиба пуансон-оправки.The purpose of the invention is to improve the quality of parts when bending thick sheet blanks by eliminating the bending of the punch mandrel.

С зтой целью гибочный узел устрой .ства дл изготовлени пустотелых деталей типа втулок из листовых заготовок , содержащий пуансон-оправку и матрицу первого перехода гибки, установленные с возможностью возвратнопоступательного перемещени во взаимно перпендикул рных плоскост х, а также матрицу второго перехода гибки, снабжен упором, взаимодействующим с пуансоном-оправкой и размещенным с противоположной от нее стороны относительно матрицы первого перехода гибки, а второго перехода гибки смонтирована за матрицей первого перехода гибки в нашравлении рабочего хода пуансон-оправкн.For this purpose, a bending assembly of a device for manufacturing hollow parts such as bushings from sheet blanks, comprising a plug-mandrel and a first bending transition matrix, installed with the possibility of reciprocal movement in mutually perpendicular planes, as well as a second bending transition matrix, provided with an abutment, interacting with the punch-mandrel and placed on the opposite side relative to the matrix of the first transition are flexible, and the second transition are flexible mounted behind the matrix of the first transition flexible in the direction of the working stroke of the punch-mandrel.

На чертеже схематически изображен предлагаемый гибочный узел устройства дл изготовлени пустотелых деталей типа втулок.The figure shows schematically the proposed bending unit of the device for manufacturing hollow-type parts such as bushings.

Гибочный узел содержит пуансоноправку 1, матрицу 2 первого перехода гибки, контактирующий с последней неподвижный упор 3 и матрицу 4 второго перехода гибки. С упором 3 жестко св зан отрезной нож 5, взаимодействующий с отрезным ножом 6, размещенным на матрице 2 первого переходаThe bending unit contains a key 1, a matrix 2 of the first bending, a fixed stop 3 in contact with the last, and a matrix 4 of the second bending. A cut-off knife 5, which interacts with a cut-off knife 6 located on the matrix 2 of the first transition, is rigidly connected with the stop 3.

25 гибки. Пуансон-оправка 1 и матрица 2 первого перехода гибки св заны с механизмами (на чертеже не изображены) их возвратно-поступательного перемещени во взёшмно перпендикул рных25 bending. The mandrel-punch 1 and the die 2 of the first transition are flexibly connected with the mechanisms (not shown) of their reciprocating movement in a vertical perpendicular

Claims

30 planes. The matrix 4 of the second bend is located behind the matrix of the first bend in the direction of the working stroke of the punch-mandrel 1 and is designed as a stationary body with a closed cavity, which has a lead-in section on the input side of the workpiece, the shape of the workpiece of the first transition is flexible and on the exit side of the workpiece - calibrating area Behind the matrix 4, a punch 7 can be installed, which is associated with the mechanism (not shown) of the reciprocating movement in the direction of the longitudinal axis alibruyuschego matrix portion 4. Reference numeral 8 denotes the slab, and numeral 9 the strip material. Bending node works as follows. The straightening rollers (not shown) feed the strip 9 by the amount of sweep of the part to the bending unit. When moving the matrix 2, the knives 5 and 6 cut off the workpiece 8, and then the matrix 2 presses it along the punch. Correction 1 . Then the punch-mandrel 1 moves in the direction of the working stroke and pushes the workpiece of the first bending to bend into the matrix 4, where the final design of the sleeve and its calibration are carried out. If it is necessary to manufacture the rivet, the formation of the head of the rivet is carried out by the punch 7. After the completion of the manufacturing process of the part, the moving tools return to their original position. Then the cycle repeats, and the next part pulls the previous one out from the matrix 4 into the storage bin (not shown). Mechanisms for moving movable tools can be driven, for example, by means of a camshaft (not shown). . Using the proposed assembly, it is possible to obtain parts with a rectangular round, triangular, hexagonal profile, changing, respectively, the profile of the forming tools: a mandrel-mandrel and a second bend. The technical and economic effect from the use of this invention is determined by the expansion of technological capabilities, the use of this node for bending both thin-sheet and thick-plate blanks. The invention The bending assembly of a device for the manufacture of hollow parts of the type of sleeves from sheet blanks, comprising a plug-mandrel and a first bending transition matrix / installed with the possibility of reciprocating movement in mutually perpendicular planes, as well as a second transition bending matrix, By the fact that, in order to improve the quality of parts when bending thick plates, by eliminating the deflection of the punch, the second bend transition matrix is mounted behind the first transition matrix and bending in the direction of the working stroke of the mandrel-punch, and the node is provided with an abutment cooperating with a punch-oprakoy protivopolozhnoyot placed with its side relative to the matrix of the first transition bend.
