Abstract

Изобретение относитс к обработке металлов давлением. Цель изобретени - повышение производительности. При повороте кулачка 7 против часовой стрелки рычаг 6 выходит из контакта с кулачком 7, ползун 3 под действием пружины 5 перемещаетс вниз и отрезает необходимую часть от заготовки 15 с помощью ножа 4. Выступ 12 ножа 4 обеспечивает вместе с поверхностью в паза 13 разворот ножа 4 относительно оси 11. Нижн часть ножа 4 выполнена Г-образной и способствует беспреп тственной подаче в зону резки заготовки 15. Благодар такому выполнению при обратном перемещении (вверх) нож 4 не перекрывает направление подачи заготовки 15 на обработку. 1 з.п. ф-лы, 4 ил.The invention relates to the processing of metals by pressure. The purpose of the invention is to increase productivity. When turning the cam 7 counterclockwise, the lever 6 comes out of contact with the cam 7, the slider 3 under the action of the spring 5 moves down and cuts the necessary part from the workpiece 15 with the help of the knife 4. The protrusion 12 of the knife 4 provides, together with the surface, into the groove 13 of the knife 4 with respect to axis 11. The lower part of the knife 4 is made L-shaped and facilitates unhindered feeding of the workpiece 15 to the cutting zone. Due to this design, when moving back (up) the knife 4 does not obstruct the feed direction of the workpiece 15 for processing. 1 hp f-ly, 4 ill.

Claims

Claim;

1. Cutting device, comprising a housing, a fixed knife mounted therein, a slider with movable knife, spring-loaded relative to the housing, a cam-lever mechanism for moving the slide, and the rest of it in order to increase productivity , it is equipped with a spring, one end of which. the swivel is pivotally mounted on the slider, and the other is pivotally mounted on the movable knife, with a stop placed on the slider to interact with the movable knife, the movable knife is made with two protrusions forming a two-arm lever and located on the end opposite to its cutting edge, and installed in the slider with the possibility of rotation on an axis perpendicular to the cutting plane, and the possibility of interaction with one of its protrusions with the said spring, and the other with a groove made in the housing.

2. The device according to π. I, characterized in that the lower part of the movable knife is made L-shaped.
