(54) МНОГОПОЗИЦИОННЫЙ ГИБОЧНЫЙ ШТАМП(54) MULTIPOSICAL FLEXIBLE STAMP

1one

Изобретение относитс к обработке металлов давлением, а именно к штампам дл изготовлени деталей гибкой.The invention relates to the processing of metals by pressure, in particular to dies for the manufacture of flexible parts.

Известны многопозиционные гибочные штампы, содержащие закрепленный на подвижной плите пуансона, смонтированную на неподвижной плите матрицу .с жестким основанием,а также узел центрировани заготовок. Пуансон и матрица выполнены со ступенчатыми рабочими поверхност ми, причем кажда из взаимодействующих ступеней матрицы и пуансона соответствует одному типоразмеру изгибаемых деталей 1.Multiple bending dies are known that contain a matrix mounted on a movable plate of a punch mounted on a fixed plate with a rigid base, as well as a centering unit for workpieces. The punch and the die are made with stepped work surfaces, each of the interacting steps of the die and the punch corresponds to one dimension type of the bent parts 1.

Однако штампы такой конструкции предназначены дл изготовлени деталей ограниченных типоразмеров.However, stamps of this design are intended for the manufacture of parts of limited sizes.

Цель изобретени - расширение номенклатуры изготовл емых деталей.The purpose of the invention is to expand the range of manufactured parts.

С зГтой целью в гибочном штампе, содержащем закрепленный на подвижной плите пуансон со ступенчатой рабочей поверхностью, кажда из ступеней которой соответствует одному типоразмеру изгибаемых детгшей, смонтированную на неподвижной плите матрицу с жестким основанием и ступенчатой рабочей поверхностью, соответствующей ступенчатой поверхности пуансонаFor the purpose of a bending punch containing a punch mounted on a movable plate with a stepped working surface, each of the steps of which corresponds to a single dimension of bending dehtsha mounted on a fixed plate matrix with a rigid base and a stepped working surface corresponding to the stepped surface of the punch

а также узел узел центрировани заготовок , ступенчатьми выполнены бокова поверхность матрицы и соответствующа ей бокова поверхность пуансона, основание матрицы смонтировано с возможностью возвратно-поступательного перемещени в направлении хода подвижной плиты, а штгилп снабжен размещенной между основанием матригдаas well as the node for centering the workpieces, the side surface of the matrix and the corresponding side surface of the punch are made in steps, the base of the matrix is mounted with the possibility of reciprocating movement in the direction of travel of the movable plate, and the stem plate is provided with a matrix placed between the base

и неподвижной плитой с возможностью установочного перемещени в плоскости гибки опорной пластиной с опорньми выступами заданной высоты. and a fixed plate with the possibility of installation movement in the plane are flexible with a support plate with supporting protrusions of a given height.

Узел центрировани заготовки может. быть выполнен в виде несущей за готовку ползушки,установленной с воз-, можностью перемещени в направлении перпендикул рном плоскости гибки, на подвижной плите, и регулировочногоThe centering unit of the workpiece can. be made in the form of a carrier for the preparation of a slider installed with the possibility of movement in the direction perpendicular to the plane of bending, on a movable plate, and an adjusting

На фиг.1 изображей держатель с изогнутыми детал ми, вид сбоку; на фиг.2 - то же, вид в плане; на фиг.25 разрез штампа по плоскости гибки; на фиг.4 - неподвижна плита с матрицей, вид в плане.In Fig. 1, a holder with curved parts, side view; figure 2 is the same, the view in the plan; on Fig cut of the stamp on the plane are flexible; figure 4 is a fixed plate with a matrix, view in plan.

Claims

The stamp contains a punch 2 mounted on a movable plate 1 and a coulter, 0 on a fixed plate 3, a matrix 4 with a rigid base: 5. A punch 2 and a matrix 4 have stepped side surfaces b and 7, each of the steps of which correspond to one size the stamp of parts 8. The matrix 5 is based 5 installed with the possibility of reciprocating movement in the direction of travel of the movable plate 1, and between the base 5 and the fixed plate 3 there is a support plate 9 installed with the possibility of translational in the plane are flexible and having supporting lugs 10 and 11 of a given height. The support plate 9 is connected with the fixed plate 3 with the setting screw 12. On the fixed plate 3, the centering-blank assembly 13 is also made, made in the form of the slider 14 and the adjusting screw 15, connecting the slider 14 with the matrix 4, and through it . Moving plate 3 “A catcher 17 with blanks 13 is placed on the catcher x16 of the sliders 14. A wedge 18 is rigidly fixed on the movable plate 1 and mounted spring-loaded to the plate 1 with the press 19. The matrix 4 is made with the side part 20 movable in the plane of bending. zatel of a standard size of the received de-tali. The stamp works as follows. A cassette 17 with a group of direct pins - wire leads is installed on catchers 16 of the slide 14. Using the screw 15 according to the pointer of the standard size, the slide 14 is moved to the position corresponding to the specified size of the part (the blanks 13 are placed on the corresponding step side surface 6 of the matrix). When the movable plate 1 is lowered, the clamp 19 presses the blanks 13 against the matrix 4. Then the punch 2 acts on the blanks 13 and bends them, and at the end of the downward movement underneath them on the base 5. Under the influence of the wedge 18 the movable side 20 moves to direction, perpendicular to the direction of movement of the punch 2, and undercut (or flatten) the bent ends of the blanks 13. The proposed stamp allows you to manufacture parts of various sizes with high performance due to the simultaneous processing of several blanks. Claim 1. Multi-position bending stamp containing a punch fixed on a movable plate with a stepped working surface, each of the steps of which corresponds to one standard size of bend parts, mounted on a fixed plate a matrix with a rigid base and a stepped working surface corresponding to the stepped surface of the punch, as well as a node centering the workpieces, characterized in that, in order to expand the range of manufactured parts, the side surface is stepped be the matrix and its corresponding side surface of the punch, the base matrix is mounted with the possibility of reciprocating movement in the direction of the movable plate stroke and stamp is provided disposed between the base matrix and the stationary platen with the possibility of adjusting movement in the plane of bending of the base plate, with the bearing projections predetermined height.

2. Stamp POP.1, characterized in that the centering unit of the workpiece is designed as a workpiece-carrying slider mounted for movement in a direction perpendicular to the bending plane on the fixed plate, and an adjustable screw connecting the slider with the fixed plate.
