(54) ШТАМП ДЛЯ ОБРАБОТКИ ПОЛОСОВОГО И ЛЕНТОЧНОГО МАТЕРИАЛА(54) STAMP FOR TREATMENT OF STRIP AND BELT MATERIAL

1one

Изобретение относитс к холодной обработке металлов давлением и может быть использовано дл обработки полосового и ленточного материала.The invention relates to the cold working of metals by pressure and can be used to process strip and strip material.

Известен штамп дл обработки полосового и ленточного материала, содержащий закрепленные на верхней плите пробивные пуансоны и отрезной нож, смонтированный на нижней плите шаговый упор, направл ющие дл , перемещени материала, съемник и сбрасыватель 1 .A stamp for processing strip and tape material is known, comprising punched punches fixed to the upper plate and a cutting knife mounted on the lower plate with a stepping stop, guides for moving the material, a puller and a resetter 1.

Однако известный штамп имеет сложную ,Q конструкцию.However, the well-known stamp has a complex, Q design.

Цель изобретени - упрощение конструкции штампа.The purpose of the invention is to simplify the stamp design.

Поставленна цель достигаетс тем, что в штампе дл обработки полосового и ленточного материала, содержащем закреплен- is ные на верхней плите пробивные пуансоны и отрезной нож, смонтированные на нижней плите шаговый упор, направл ющие дл перемещени материала, съемник и сбрасыватель , отрезной нрж расположен перед пробивными пуансонами, а шаговый упор 20 расположен за пробивными пуансонами по ходу подачи материала, съемник закреплен консольно, а сбрасыватель выполненThe goal is achieved by the fact that in the stamp for processing strip and tape material, containing punch punches fixed to the top plate and a cutting knife, a stop stop mounted on the bottom plate, material transfer guides, a puller and a resetter, the cutting edge is located punch punches, and the step support 20 is located behind the piercing punches in the course of the material feed, the puller is fixed console, and the resetter is made

в виде по меньшей мере одной подпружиненной в направлении, перпендикул рном направлению подачи материала, планки, на которой со стороны нижней плиты выполнен скос, взаимодействующий с материалом. На фиг. 1 изображен штамп, общий вид в разрезе; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - разрез Б-Б на фиг. 2; на фиг. 4 - второй вариант исполнени сбрасывател .in the form of at least one spring-loaded in the direction perpendicular to the direction of the material supply, a bar on which a bevel is made interacting with the material from the bottom plate side. FIG. 1 shows a stamp, a general view in section; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows a second embodiment of the resetter.

Штамп дл обработки полосового и ленточного материала содержит нижнюю плиту 1 и установленную на ней матрицу 2. На матрице 2 закреплены направл ющие 3 и 4. В пазах направл ющей 4 установлен сбрасыватель, вьнюлненный в виде планок 5, свободно установленных на внешних винтах 6, ввернутых в съемник 7, закрепленный на направл ющей 4 консольно. На винтах 6, между головками 8 и планками 5 установлены пружины 9.The stamp for processing the strip and tape material contains the bottom plate 1 and the matrix 2 mounted on it. On the matrix 2, the guides 3 and 4 are fixed. In the slots of the guide 4 there is a reset device installed in the form of bars 5, freely mounted on external screws 6 screwed puller 7 mounted on guide 4 console. On the screws 6, between the heads 8 and the strips 5 installed spring 9.

Claims

At the end of the strip 5 from the side of the matrix 2 is made a bevel 10, interacting with the material 11 (strip or tape). A bottom plate 13, a punch holder 14 with punch punches 15 and a cutting knife 16 are fixed on the upper plate 12. A step support 17 is fixed on the matrix. A roller 18 can be fixed on the bar 5, which is a clamp. The stamp for processing strip and tape material works as follows. The material 11 (strip or ribbon) is fed to the stepper stop 17. When the upper plate 12 moves down, the punch punches 15 pierce the holes in the material 11, and the cutting knife 16 cuts the workpiece from the material 11. During the upper plate 12 moves up, the cutting punches 15 carry the workpiece up and it, resting against the bevels 10, moves the strips 5, compressing the spring 9. At the moment of contact with the puller 7 and the punch output from the workpiece, the screws 6 under the action of the springs 9 move to the left (Fig. 3) and throw the workpiece out of the working area of the stamp through the gap between guide 3 and puller 7. Then the cycle is repeated. The bars 5 simultaneously press the material 11 against the guide 3. When mounting the roller 18 on the bar 5, the material 11 is pressed against the guide with this roller. The proposed die made allows us to simplify the construction of the known stamps of the same purpose and to ensure greater safety of operation. Claims for processing strip and band material containing punched punches mounted on the top plate and a cutting knife mounted on the bottom plate a step support, material transfer guides, pullers and a resetter, characterized in that, to simplify the design, the cutting knife is located in front of the piercing punches, and the step support is located behind the piercing punches in the course of the material feed, the puller is fixed console, and the resetter is made in at least one spring loaded in the direction perpendicular to the feeding direction of the material strips, which is formed by the bevel of the lower plate, which interacts with the material.
