Description

Известны станки дл  вырубки отверстий при изготовлении сит из листовых материалов с шаговым относительным перемещением заготовки и инструмента в продольном, и поперечном направлени х. Однако такие станки сложны по конструкции.Known machines for cutting holes in the manufacture of sieves of sheet materials with step relative movement of the workpiece and the tool in the longitudinal and transverse directions. However, such machines are complex in design.

В описываемом станке указанный недостаток устранен тем, что дл  упрощени  конструкции вырубные инструменты - пуансон и матрица помещены на двух поворотно посаженных на ходовых винтах рычагах, из которых матричный скользит по неподвижной направл ющей, а рычаг , несущий пуансон, совершает возвратно-вращательное движение под вли нием расположенного над ним кулачкового вала и возвратной пружины .In the described machine, this drawback is eliminated by the fact that to simplify the design, the cutting tools — the punch and the die are placed on two pivotally mounted arms on the spindles, from which the matrix slides along a fixed guide, and the punch-carrying lever performs a reciprocating rotational movement the cam shaft and the return spring located above it.

На фиг. 1 изображен станок; на фиг. 2 - вид по стрелке Л на фиг. 1.FIG. 1 shows a machine; in fig. 2 is a view along arrow L in FIG. one.

Станок дл  вырубки отверстий при изготовлении сит состоит из рамы 1, кулачкового вала 2, поворотного рычага 3, несущего пуансон 4 и перемещающегос  по ходовому винту 5 с перекрестной нарезкой 6, поворотного рычага 7, несущего матрицу 8 и перемещающегос  по ходовому винту 9 с перекрестной нарезкой 10, и механизма 11 перемещени  листа 12.The machine for cutting holes in the manufacture of sieves consists of frame 1, camshaft 2, pivoting lever 3, carrying punch 4 and moving along crosshead screw 5 with cross-cutting 6, rotary lever 7 carrying matrix 8 and moving along crosscut screw 9 with cross-cutting 10, and the sheet moving mechanism 11.

Лист 12 закладываетс  между рычагами 3 и 7. При вращении вала 2, передаваемом через храповой механизм 13 и зубчатую передачу 14 ходовым винтам 5 и Я рычаги 5 и 7 совершают прерывистое возвратновращательное движение, причем во врем  их остановки кулачок 15 вала 2, нажима  на рычаг 3, пробивает в листе 12 отверстие.The sheet 12 is laid between the levers 3 and 7. When the shaft 2 is rotated through the ratchet mechanism 13 and the gear train 14 to the driving screws 5 and I, the levers 5 and 7 perform an intermittent return movement, and during their stop the cam 15 of the shaft 2 presses the lever 3, punches a hole in sheet 12.

После того, как будет пробит весь р д отверстий в листе 12, механизм 11, приводимый храповым механизмом 16, переместит лист 12 вбок на один щаг.After the entire row of holes in sheet 12 has been pierced, mechanism 11, driven by ratchet mechanism 16, will move sheet 12 sideways by one step.
