Description

Изобретение относитс к обработке металлов давлением и штамповой оснастке.The invention relates to metal forming and die tooling.

Известен штамп дл изготовлени конических деталей, содержащий пуансон , матрицу прижим и выталкиватель 1 .A stamp for making conic parts is known, comprising a punch, a pressing nip and an ejector 1.

Этот штамп не позвол ет штамповать детали с буртиком.This stamp does not allow stamping of collar parts.

Наиболее близким по технической сущности и достигаемому результату к изобретению вл етс штамп дл изготовлени конических деталей, содержащий в верхней части подвижную плиту с закрепленными на ней вырубным пуансоном с режущей кромкой, охватывающий его съемник, расположенные внутри вырубного пуансона выт жную матрицу и пуансон формовки дна, в нижней части неподвижную плиту, внутри которой расположены кольцо поддержки заготовки при выт жке и выт жной пуансон 2.The closest in technical essence and the achieved result to the invention is a stamp for making conical parts, which contains in the upper part a movable plate with a cutting punch with a cutting edge fixed on it, covering its puller, an extracting die and a punch of bottom forming, in the lower part there is a fixed plate, inside of which there is a support ring for the workpiece during drawing and a drawing punch 2.

Этот штамп не позвол ет получать . детали с буртиком, так как в нем отсутствуют пуансон и матрица фор ловки буртика.This stamp does not allow to receive. flanged parts, since there is no punch and die for the collar.

Цель изобретени - получение детале .й с буртиком.The purpose of the invention is to obtain parts with a collar.

Указанна цель достигаетс тем, что штамп дл изготовлени конических деталей, содержгиций в верхней части П9Дважв)по плиту с закрепленным на ней вырубным пуансонсм с режущей кромкой, с сватываккий его съемник, расположенные внутри вырубного пуансона выт жную матрицу и пуансон формовки дна, а а нижней части неподвижную плиту, закрепленную на ней вырубную матрицу, внутри которой расположены кольцо поддержки заготовки при выт жке и выт жной пуаНсон, снабжен матрицей и пуансоном формовкиThis goal is achieved by the fact that a stamp is used for making conic parts, contents in the upper part of D9 Dvazhv) on a plate with a cutting punch attached to it with a cutting edge, with his puller set, located inside the cutting punch of the bottom forming die and punch. the parts of the fixed plate, the die-cutting matrix fixed on it, inside of which the support ring of the workpiece is located during drawing and the exhaust tube, is provided with a die and a forming punch

15 буртика, а также кольцом обрубки15 collar as well as a chipping ring

фланца детали, при этом матрица формовки буртика размещена внутри вырубного пуансона и подпружинена в осевом направлении, кольцо обрубкиflange details, while the matrix forming the collar is placed inside the cutting punch and is spring-loaded in the axial direction, the ring of chipping

20 фланца установлено внутри вырубной матрицы с возможностью вертикального перемещени , а на вырубном пуансоне выполнена дополнительна режуща кромка, взаимодействующа с кольцом обрубки фланца.The 20 flange is installed inside the punch die with the possibility of vertical movement, and on the cutting punch there is an additional cutting edge interacting with the flange punching ring.

Claims

FIG. Figure 1 shows a stamp, a longitudinal section, to the right of the axis of symmetry in the initial position, and to the left at the moment of the end of the stamping; in fig. 2 - the detail is ready. The stamp contains in the upper part a movable plate 1 with a hollow cutting punch 2 fixed on it with a cutting edge located along the outer contour, covering its puller 3 with guides 4 and springs 5 located inside the cutting punch 2 matrix of the shoulder bead molding interacting with the ring 7, spring-loaded disc springs 8, exhaust matrix 9 with a ring 10, spring-loaded disc springs 11 sitting on guide 12, and a punch 13 forming the ridges on the bottom of the part with an ejector pin 14 and supporting the 15, in the lower part of the punch there is a fixed plate 16, a cutting matrix 17 fixed on it, inside which the clamp 18 is successively located, a ring 19 of the flange of the part, a punch 20 for shaping the flange with pushers 21 / ring 22 for supporting the workpiece when extracting from the pusher 23 and exhaust punch 24. An additional cutting edge is formed on the inner contour of the cutting punch 2, which interacts with the ring 19 of the flange of the part. The stamp works as follows. Stamped material in the form of a strip or tape (not shown) is fed into the stamp. During the working stroke, the cutting punch 2 and the die 17 are cut down a blank (not shown) in the shape of a circle. During the further course of the upper part of the punch downwards, the conical wall of the part 25 is stretched by the exhaust punch 24 and the die 9 with the assistance of the clamp 18, the punch 2 and the supporting ring 22, the bead is formed by the punch 20 according to the matrix b, the forming of the zigos on the part is punched 13 and 24 At the end of the stroke of the upper part of the stamp, the flange is cut off by an additional cutting edge of the cutting punch 2 and the ring 19 of the part flange of the part with the assistance of a clamp 18 and a die B. The use of the proposed stamp ensures that Leaf with collar in one stroke. Claim for making conical parts comprising in the upper part a movable plate with a cutting punch with a cutting edge fixed on it, enveloping its puller, an extracting die and a punch for forming the bottom, and the lower part of the fixed plate, a cutting matrix fixed on it, inside which the support ring of the workpiece is located during drawing and a drawing punch, which is characterized by the fact that, in order to obtain parts with a collar, packed with a die and a punch for forming a collar, as well as a ring for trimming the flange of the part; interacting with collar flanging.
