Description

между собой шатунов 11 и 12. Шатун 12 шарнирно соединен с качающимс рычагом 8. Кривошип 9 выполнен регулируемым посредством эксцентриковой втулки 13.between the rods 11 and 12. The connecting rod 12 is pivotally connected to the swing arm 8. The crank 9 is made adjustable by means of an eccentric sleeve 13.

Механизм реза снабжен двум уравновешивател ми 14 и 15. Уравновешиватель 14 жестко соединен с валом 16 кривошипа 9, а уравновешиватель 15 - с эксцентриковой втулкой 13.The cutting mechanism is equipped with two counterbalances 14 and 15. The counterbalance device 14 is rigidly connected to the shaft 16 of the crank 9, and the counterbalance device 15 is connected with the eccentric bushing 13.

Работает механизм следующим образом.The mechanism works as follows.

От электродвигател 17 через клиноременную передачу 18 привод тс во вращение кривошипы 9 и 10, а каретка 4 механизма реза через шатун 12 получает возможность возвратно-поступательного перемещени . Через зубчатые колеса 19-21, цепной вариатор 22 и цепные передачи 23 и 24 привод тс во вращение подающие ролики 25 переднего и заднего механизмов подачи.From the electric motor 17, via the V-belt transmission 18, the cranks 9 and 10 are rotated, and the carriage 4 of the cutting mechanism through the connecting rod 12 is allowed to reciprocate. Through the gears 19-21, the chain variator 22 and the chain drives 23 and 24, the feed rollers 25 of the front and rear feed mechanisms are driven into rotation.

Материал, подлежащий обработке, протаскиваетс через вращающуюс правильную рамку 1. Выправленный материал проходит через нож 6, закрепленный на «аретке. Во врем хода каретки вперед происходит отрезка на ходу стержн заданной длины, с помощью отрезного ножа 7. Отрезанный стержень падает на транспортер механизма 5 удалени , отводитс от автомата и сбрасываетс в тару (на чертежах не показана).The material to be processed is drawn through the rotating right frame 1. The straightened material passes through the knife 6 fixed on the grid. During the advance of the carriage, a section is cut at a stroke of a given length with the help of a cutting knife 7. The cut rod falls on the conveyor of the removal mechanism 5, retracts from the machine and is dropped into the container (not shown).

Длина стержн определ етс величиной подачи материала за врем одного двойного хода каретки. Регулировка величины подачи проволоки устанавливаетс посредством цепного вариатора 22.The rod length is determined by the amount of material feed during one double carriage stroke. The adjustment of the wire feed amount is established by means of a chain variator 22.

Уравновещивание кривошипа 9 и других св занных с ним масс осуществл етс при повороте эксцентриковой втулки 13, когда происходит либо сложение, либо вычитание масс уравновещивателей 14 и 15. Это обеспечивает уравновешивание на всем диапазоне регулировки.The balancing of crank 9 and other masses associated with it is carried out by turning the eccentric bushing 13, when either the addition or subtraction of the masses of counterbalances 14 and 15 occurs. This provides balancing over the entire adjustment range.

Claims

1. The volatile mechanism for cutting the trimming machine for the manufacture of short

rods, for example, electrodes, containing two interacting carriages located on a reciprocating carriage, a knife, one of which is fixed on the carriage and the other movable during cutting, and an actuator that informs the carriage and the movable knife to move by means of two crank - crank mechanisms with synchronous and counter-rotating crankshafts, moreover, the carriage is connected to the connecting rod of one of the curved mechanisms with the help of a swinging lever mounted on it, distinguished by then, in order to reduce the inertia of the cutting mechanism and increasing the

its speed, the movable knife is mounted on a swinging arm, which is pivotally connected to the crank of one crank mechanism by the crank of another crank mechanism connected by a hinge to the crimper of the first.

2. The volatile cutting mechanism of claim 1, characterized in that, in order to ensure the coincidence of the speeds of the carriage and the material to be divided when cutting rods of different

length, one of the curvatures is made adjustable by an eccentric bushing.

3. The volatile cutting mechanism for PP. 1 and 2, characterized in that, in order to balance the rotating and reciprocating moving parts of the cutting mechanism throughout the crank adjustment range, it is equipped with two balance arms, one of which is rigidly connected to the shaft of the adjustable curvature, and the other is rigidly connected to the eccentric bushing for adjusting the crank.
