Изобретение относитс к фикснруюощм устройствам к вырубным штампам и может быть использовано дд . фиксации полосы на рабочей позиции штампа, работающего в автоматическом режиме.This invention relates to fixed punch die tools and dd can be used. fixing the strip on the working position of the stamp operating in automatic mode.

Известен шаговый упор к пробивному штампу , содержаищй установленный на нижней плите штампа подпружиненный стержень, в;заимодействующий с материалом и приводимый в движение прижимом-съемником t.Known step emphasis to the breakdown stamp, containing a spring-loaded rod mounted on the lower plate of the stamp, borrowed with the material and set in motion by the stripper t.

Известный шаговый упор не обеспечивает возможйостн фиксации материала на рабочей позшщи штампа, работающего .в автоматическом режиме;The well-known step support does not provide for the possibility of fixing the material on the workplace of a punch working in automatic mode;

Целью изобретени вл етс обеспечение возможности фиксации материала на рабочей позиции штампа.The aim of the invention is to provide the possibility of fixing the material at the working position of the stamp.

Цель д остигаетс тем, что в стержне выполнен паз, шаговый упор снабжен шарнирно установленным в пазу двуплечим рычагом, один конец которого подпружинен, а на другом со стороны нижней плиты выполнен скос, взаимодействуюпшй с материалом .The goal is achieved by the fact that a rod is made a groove, the step support is provided with a double-arm lever hinged in the groove, one end of which is spring-loaded, and on the other side of the bottom plate there is a bevel that interacts with the material.

Шаговый упор может быть снабжен закрепленными на прижиме-сьемга«ке толкател мн. взаимодействую1цими со стержнем.The step support can be provided with a pusher fixed to the clamping lever. interacting with the rod.

На фиг. 1 изображен предлагаемый шаговый упорв верхнем положении, общий вид; на фиг. 2 - то же, в момент опускани ; на фиг. 3 - то же, в момент вырубки детали; на фиг. 4 - то же, сечение, по А-А на фиг. 3; на фиг. 5 - то же, в момент подачи материала.FIG. 1 shows the proposed stepper stop up position, general view; in fig. 2 - the same, at the time of lowering; in fig. 3 - the same at the moment of cutting the part; in fig. 4 is the same section, along A-A in FIG. 3; in fig. 5 - the same at the time of submission of the material.

Шаговый упор к вырубному нггампу содерИогг стержень 1, на котором при помощи оси 2 1закреплен двуплечий рычаг 3.The step support to the cutting ngampa contains a rod 1, on which, using the axis 2 1, a two-armed lever 3 is fixed.

Один конец двуплечего рычага 3 опираетс на стержень 1, а другой конец подпружинен пру5КИНОЙ 4, установленной в пазу, выполненном в стержне I. Стержень 1 установлен в нижней плите 5 иггампа с возможностью вертикально|-о перемещенн и подпружинен пружиной 6. Пружина 6 удерживаетс в нижней плите 5 пробкой 7.One end of the two shoulders lever 3 rests on the rod 1, and the other end is spring-loaded with a spring 5 installed in a groove made in the rod I. The rod 1 is installed in the bottom plate 5 of the Iggamp with the possibility of vertically displaced and spring-loaded 6. The spring 6 is held in bottom plate 5 stopper 7.

Claims

The rod 1 is kept from rotation around the axis by a pin 8, one end of which is fixed in the rod 1, and the other is mounted in a groove 9 made in the bottom plate 5. The rod 1 is seated with a shoulder 10 that limits the movement of the rod 1 in the vertical direction. The end of the two shoulders lever 3, resting on the rod 1, is made with a bevel, 11. The bevel 11 is made on the side of the bottom plate 5. On the top plate 12 of the shtamp there is a cutting punch 13 and a clamp-puller 14 for the feed material 15. The presses-puller 14 is fixed on the pushers 16, interacting with the rod 1. In the bottom plate 5 of the stamp is installed matrix 17 with hitch for removing the cut-out parts 18. Feed material 15 interacts with rod 1 strap aI 19 between bores 20. 20. Two shoulders lever 3 is installed in slot 21, WY with poleine in rod 1, and rests with one end into bottom 22 of slot 21. Stepper emphasis to die cutting works leduyuschim way. In the initial position, the press-remover 14, the pushers 16 and the punch 13 are in the upper position. The rod 1 under the action of the spring 6 is raised to the upper position. The feed material 15 rests on the rod 1 and is fixed on the working posture. Two-lever lever 3 under the spring 4 takes a horizontal position. In the case of a puller 14, the pushers 16 press the rod 1, which moves the spring 6 downward, and the double-arm lever 3 slides along the material 15 with a bevel 11, rotates around the axis 2, compressing the spring 4. When the top point of the two arm 2 is slid with the bevel 11 is located below the material 15, then the spring 4 rotates the double-arm lever BOKPJTP axis 2 against the stop into the bottom 22 of the groove 21. The puller 1J presses the material 15 to the matrix 17, and the punch 13 cuts down the part, 18. Then the upper plate 12 goes up, the clamper 14 releases the material. The pushers 16 come out of interaction with the rod 1. The spring 6 lifts the rod 1 until the two shoulders 3 rest against the material 15. The punch 13 leaves the material 15, which is moved in the direction of the rod 1. When the hole 20 E1, the position above the rod 1, spring 6 Yygynima ygov upper position. Upon further movement of the material 15, the jumper 19 rests on the rod 1. The supply of the material 15 is stopped. Then the cycle is repeated. Claim 1. Stepper stop to punch die, containing spring-loaded rod mounted on the bottom plate, interacting with the material and driven by a pinch-holder, characterized in that in order to ensure the possibility of fixing the material at the working position of the string, working in ITffifoMaiiWeckoii mode , ha3 is retracted, the schagovy emphasis is supplied with a pivotally mounted1) 1 m in the groove with a two-arm lever, one end of which. podpravna relative to the rod, and on the other from the bottom plate is made bevel, interacting with the material .;

2. The stress of claim 1, which is different. the fact that en is equipped with pushers attached to the clamping puller interacting with the rod. Sources of information taken into account during the examination 1. Copyright copyright USSR № 211503 ,, кл. B 21.0 28/14, 1968.
