НА СТЕРЖНЯХON THE RODS

Изобретение относитс к обработке металлов давлением, в частности, к штампу дл однопереходной высадки утолщеиий на стержн х .The invention relates to the processing of metals by pressure, in particular, to a stamp for the single junction of the thickening of the rods.

Известен штамп дл однопереходной высадки утолщений (ka стержн х при длине высаживаемой части, превышающей критическую , содержащий верхнюю и ннжиюю плиты с соответственно закрепленными пуансоном и матрицей, а также размещенный между плитами поддерживающий инструмент, выполненный в виде раздвижных в плоскости, перпендикул рной к движению пуансона, секций с клином 1.A stamp is known for a single junction of setting up the bulges (ka rods with a length exceeding the critical part, containing upper and lower plates with respectively fixed punch and die, as well as a supporting tool placed between the plates, made in the form of sliding in a plane perpendicular to the movement of the punch , sections with a wedge 1.

Недостатком известного штампа вл етс быстрый износ секций поддерживающего инструмента .A disadvantage of the known stamp is the rapid wear of the supporting tool sections.

Цель изобретени - уменьшение износа секций поддерживающего инструментаThe purpose of the invention is to reduce wear of the supporting tool sections.

Указанна цель достигаетс тем, что в штампе дл одиопереходной высадки утолщеиий на стержн х при длине высаживаемой части, превышающей критическую, содержащем верхнюю и нижнюю шшты с соответственно закрепленными на них пуансоном и матрицей, а также размещенный между плитами поддерживающий инструмент, выполненный в виде раздаижных в плоскости, перпендикул рной движению пуансона, секций к механизма зажима секций с клином, механизм зажима секций выполнен в виде подпружиненного и щарнирно закрепленного на иижней плите одноплечего рьпага с пазом на его свободном конце, клиновых сменных гу This goal is achieved by the fact that in the stamp for odiotransitional landing of thickening on the rods with the length of the disembarked part exceeding the critical one, containing the upper and lower shshty with a punch and die fixed to them, and a supporting tool placed between the plates the plane perpendicular to the movement of the punch, sections to the mechanism for clamping sections with a wedge, the mechanism for clamping sections is designed as a spring-loaded and hingedly mounted on the bottom plate of one shoulder Pag with a groove at its free end, the V-replaceable gu

to бок, жестко закрепленных в пазу рычага, и ролика, размещенного на рычаге, при зтом КЛ1Ш жестко закреплен на верхней плите с возможностью взаимодействи с роликом.To the side, rigidly fixed in the groove of the lever, and the roller placed on the lever, with this CL-1, are rigidly fixed on the upper plate with the possibility of interaction with the roller.

На фиг. 1 представлен штамп с сомкну15 тыми секци ми; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - штамп с разомкнутыми секци ми; на фщ-. 4 - разрез В-В на фиг. 3. . FIG. 1 shows a stamp with closed sections; in fig. 2 shows section A-A in FIG. one; in fig. 3 — stamp with open sections; on fng. 4 shows a section B-B in FIG. 3..

Claims

The stamp for single junction stripping of rods on rods contains a punch 2 fixed on the top plate 1 and an array 4 mounted on the bottom plate 3, as well as a supporting tool including seconi 5 pivotally mounted by means of an axis 6 on the bottom plate 3c with the sleeves 7 interacting with a sliding 8 fixed on the top plate 1 and a return spring 9. The stamp also includes a section clamping mechanism, made in the form of a single-arm lever 10, hinged on the bottom plate 3 and interacting with a “cut fixed on it is a roller And with a wedge 12 mounted on the top plate 1. At the free end of the single-arm lever 10 there are wedge replaceable jaws 13 fixed in a groove with a wedge l4 and screw 15. A single-arm lever 10 connects to the bottom plate by a spring 16. V the bottom plate 3 mounted stand 17, in which coaxially with the matrix 4 is installed ejector 18. The stamp works as follows. The workpiece. 19 is inserted through the section 5 into the matrix 4. In the initial stage of operation of the stamp of the supporting tool section 5, the ends of the sections 5 are located in the slot of the shoulder arm 10 between the wedge jigsaw 13. The lever 10 is clamped to the ends of the 6 seconds with a spring 16. Upon further movement of the upper plate 1, the punch 2 forms the upper part of the workpiece 19, after which the wedge 12 rotates; it) lever around the axis, releasing the ends of the securing section, which, under the action of the sliding wedge 8, expands, freeing the workpiece 19. The punch 2 ends A thickening is formed on the workpiece 19, after which the top plate 1 takes up the initial position, and the workpiece 19 is pushed out of the matrix 1 4. Then the cycle repeats. The proposed stamp in comparison with the known provides high resistance; sections of the supporting tool. Claims of the Invention A stamp for single junction stripping of thickenings on rods with the length of the disembarked part exceeding the critical one, containing the upper and lower plates with respectively the punch and the matrix fixed on them, as well as the supporting tool placed between the plates, made in the form of an extension in the plane perpendicular to the movement of the punch, sections and clamping mechanism of sections with a wedge characterized in that, in order to reduce wear of the supporting tool section, the section clamping mechanism is designed as When mounted on the lower plate of a single arm with a groove at its free end, wedge replaceable jaws rigidly fixed in the groove of the lever and roller placed on the lever, the hook of the cell is rigidly fixed on. gauche with the ability to interact with the roller.
