Изобретение относитс к холодной обработке металлов давлением и может найти применение при изготовлении заготовок типа стержней.The invention relates to the cold working of metals by pressure and may find application in the manufacture of workpieces such as rods.

Известен штамп дл рубки пруткового материала по основному авт. св. №31552 содержащий подвижную и неподвижную группы ножей, закрепленные на верхней и нижней плитах, при этом на боковых поверхност х ножей, закрепленных на верхней плте , предусмотрены углублени со скосами 1 . Однако в этом штампе замен ть изношенный инструмент очень сложно.Known stamp for cutting bar material on the main author. St. No.31552 contains movable and fixed groups of knives fixed on the upper and lower plates, while recesses with bevels 1 are provided on the side surfaces of the knives fixed on the upper plate. However, it is very difficult to replace a worn tool in this stamp.

Целью изобретени вл етс разработка штампа, обеспечивающего возможность замены ножей непосредственно в процессе работы.The aim of the invention is to develop a punch that provides the ability to replace knives directly in the process.

Поставленна цель достигаетс тем, что на боковых торцах ножей выполнены секторные пазы, а штамп снабжен двум скалками, кажда из которых установлена в секторных пазах соответствующей группы ножей и выполнена в виде стержн с двум лысками, расположенными во взаимно перпендикул рных плоскост х и равными по длине, по меньшей мере ширине ножей.The goal is achieved by the sector grooves at the lateral ends of the knives, and the stamp is provided with two rolling pins, each of which is installed in the sector grooves of the corresponding group of knives and made in the form of a rod with two flats located in mutually perpendicular planes and equal in length at least the width of the knives.

Верхн плита 1 штампа и обойма 2 жестко скреплены между собой. В обойме 2 устаноачены ножи 3 Г-образной формы с односторонними пазами дл удалени за-Top plate 1 stamp and the holder 2 are rigidly fastened together. In the cage 2, the knives are 3 L-shaped with one-sided grooves for removal of

готовок из межножевого пространства. В секторном пазу удерживаютс ножи скалкой 4. Нижн плита 5 несет обойму 6, где установлены ножи 7 с П-образными пазами. В секторном пазу удерживаютс cooks from the cross-breed space. In the sector slot, the knives are held with a rolling pin 4. The bottom plate 5 carries the holder 6, where the knives 7 with U-shaped slots are mounted. In the sector slot retained

ножи скалкой 4. Обойма 6 жестко соединена с нижней плитой 5, в которой выполнены наклонные пазы 8, совмешехщые с пазами 9 нижних ножей. Центрирование верхних и нижних ножей обеспечиваетс сборкой иknives with a rolling pin 4. The clip 6 is rigidly connected to the lower plate 5, in which inclined grooves 8 are made, which are combined with the grooves of 9 lower knives. The centering of the upper and lower knives is provided by the assembly and

fixed with sleeved columns. The work of the stamp is carried out in a slow manner. In the working area on the knives 7 put the workpiece. In the course of stamping knives 3, entering the grooves of 9 lower knives 7, cut the rod. The cut blanks fall into the grooves 9, and of them, along the groove 8 of the plate 5, roll into the receiving tray. The blanks remaining on the knives 7, when lifting the knives 3, are gripped by the lower surfaces of the recess 10 and roll into the same receiving tray. Tool replacement takes place directly in the working area, without disassembling or removing the stamp, as follows. The screws 11 release the knives 3 in the horizontal plane. Risks 12 are performed on the surface of the skate, the number of which is equal to half of the knives in the group. The distance between the risks is equal to the width of the j. Two flats 13 and 14 on the rolling pin 4 are circumferentially offset by 90 relative to each other; their positions correspond (in the working position mTaMnaj to the position of scratches 15 and 16. To change the tool, you need to loosen the screw 17, turn the rolling pin 4 in the direction of the arrow 18 on it, and withdraw the rock flange from the bolt with screw 17. Then, depending on the location of the Attach the knife, align the rolling pin along the axis of the rolling pin 12 with the surface 19 of the holder, turn the rolling pin around the axis in direction of arrow 18 to align the risks 15 or 16 with the risk of 20 of the holder 2, depending on the position of the knife to be replaced. cm An enamel knife, the latter freely comes out of the package. Formula for cutting a bar-shaped material according to the author St. Mb 315521, which is so that, in order to ensure a quick replacement of the knives, on their side The ends are made with pie grooves, and the stamp is provided with two rolling pins, each of which is installed in the sector grooves of the corresponding group of knives and made in the form of a rod with two flats located in mutually perpendicular planes and equal in length to at least the width of the knives.
