(54) РУЧНЫЕ НОЖНИЦЫ ДЛЯ РЕЗКИ ПРОВОЛОКИ(54) MANUAL SCISS FOR WIRE CUTTING

1one

Изобретение относитс к обработке металлов давлением, в частности к ручному инструменту дл резки проволоки.The invention relates to the processing of metals by pressure, in particular to a hand tool for cutting wire.

Известны ручные ножницы дл резки проволоки, содержащие два поворотных вокруг общей оси рычага, несущих ножи с пазами, образующими зев дл ввода разрезаемой проволоки, и соединительные элементы 1 .Known manual scissors for cutting wire, containing two rotary around a common axis of the lever, carrying knives with grooves forming the mouth for entering the wire to be cut, and connecting elements 1.

, Недостатками известных ножниц вл ютс сложность их конструкции и большой вес.The disadvantages of the known scissors are the complexity of their design and the large weight.

Цель изобретени - упрощение конструкции и умоньщение веса ручных ножниц.The purpose of the invention is to simplify the design and weight of the manual scissors.

Указанн цель достигаетс тем, что в ручных ножницах, д,л резки проволоки, содержащих два поворотных вокруг общей оси рычага, несущих ножи с пазами, образующими зев дл ввода разрезаемой проволоки , и соединительные элементы, ножи выполнены в виде пластин, в из которых по окружности с центром, расположенным на оси симметрии зева, и совпадающей с осью поворота рычагов, выполнены цилиндрическое отверстие и дуговой паз, при этом цилиндрическое отверстие одной пластины расположено напротив дугового паза другой пластины, а соединительные элементы выполнены в виде сутпенчатых пальцев, расположенных одними концами в дуговых пазах и закрепленных другими концами в цилиндрических отверсти х ножевых пластин .This goal is achieved by the fact that in hand shears, d, l wire cutting, containing two rotatables around a common lever axis, carrying knives with grooves forming the jaws for insertion of the wire being cut, and connecting elements, knives are made in the form of plates a circle with a center located on the axis of symmetry of the pharynx, and coinciding with the axis of rotation of the levers, a cylindrical bore and an arc groove are made, while the cylindrical bore of one plate is located opposite the arc groove of the other plate, and the connecting lementy sutpenchatyh embodied as fingers spaced one ends in the arcuate slots and the other ends secured in cylindrical openings stab plates.

На фиг. 1 изображены ручные ножницы дл резки проволоки, общий вид; На фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - ножева пластина.FIG. 1 shows a wire shears for cutting the wire, general view; FIG. 2 shows section A-A in FIG. one; in fig. 3 - knife plate.

Ручные ножницы дл резки проволоки со10 держат два поворотных вокруг общей оси рычага 1 и 2, несущих ножи 3 и 4 с пазами, образующими зев 5 дл ввода разрезаемой проволоки, и соединительные элементы 6. Ножи 3 и 4 выполнены в виде пластин, в каждой из которых по окружности с центром, расположенным на оси симметрии зева 5 и совпадающей с осью поворота рычагов 1 и 2, выполнены, например, цилиндрическое отверстие 7 и дуговой паз 8, при этом цилиндрическое отверстие 7 одной пластины Hand shears for cutting wire co10 hold two rotary around a common axis of the lever 1 and 2, carrying knives 3 and 4 with grooves forming the jaws 5 for entering the wire being cut, and connecting elements 6. Knives 3 and 4 are made in the form of plates, in each of which are circumferentially centered on the axis of symmetry of the pharynx 5 and coinciding with the axis of rotation of the levers 1 and 2, made, for example, a cylindrical hole 7 and an arc groove 8, while the cylindrical hole 7 of one plate

20 is located opposite the arc groove 8 of the other plate, and the connecting elements 6 are made in the form of stepped fingers located at one end in the arc grooves 8 and secured by means of washers 9 and nuts 10B of cylindrical holes 7 of the knife plates. The device works as follows. When the arms 1 and 2 are divorced, a wire (not shown) is inserted in the opening 5. When approaching the levers 1 and 2, the knives 3 and 4 rotate relative to each other around the center of the circle on which the arc groove 8 and the cylindrical hole 7 lie, and the wire is cut. The arc groove 8 serves as a guide for the connecting element 6. The proposed scissors have a simple structure and a low weight. Claims of invention Hand-held scissors for cutting wire, containing two rotatable around a common axis of the lever, carrying knives with grooves, forming
