Description

Известны устройства дл  контрол  процесса точечной контактной сварки в зависимости от количества электроэнергии, затрачиваемой при сварке одной точки.Devices are known for controlling the resistance spot welding process depending on the amount of electric power consumed during welding of a single point.

Недостатком таких устройств  вл етс  неточность их работы и сложность схем.The disadvantage of such devices is the inaccuracy of their operation and the complexity of the schemes.

Предлагаетс  схема электронного управлени  прерывателем сварочного тока, в которой врем  протекани  сварочного тока автоматически регулируетс  в зависимости от силы протекающего тока и умен):,шаетс  возможность брака от непроваров и пережогов.An electronic control circuit for a welding current interrupter is proposed, in which the welding current flow time is automatically adjusted depending on the strength of the flowing current and smart): the possibility of rejecting from penetration and burns is possible.

Это достигаетс  тем, что в схеме электронного прерывател  применен конденсатор, зар жаемый через электронную лампу. Анодна  цепь лампы включена через трансформатор тока в сварочную цепь, а цепь управл ющей сетки подключена к электродам сварочной машины. Такой прерыватель обеспечивает лучшее качество сварки, так как обеспечивает (в обратной зависимости) св зь величины сварочного тока и врем  сварки, что позвол ет с большой точностью соблюсти условие одинакового расходовани  энергии на каждую сварочную точку.This is achieved by using a capacitor charged through an electron tube in the circuit breaker circuit. The anodic circuit of the lamp is connected through a current transformer to the welding circuit, and the control grid circuit is connected to the electrodes of the welding machine. Such an interrupter provides the best welding quality, as it provides (in inverse relationship) the relationship between the welding current and the welding time, which allows a high accuracy to meet the condition of equal energy consumption per welding point.

На чертеже изображена схема электронного прерывател .The drawing shows an electronic circuit breaker circuit.

Электронный прерыватель состоит из трансформатора тока 1, включенного в контур вторичного витка сварочной машины, полупроводникового выпр мител  2, электронной лампы-триода 3, конденсатора 4, управл ющего реле 5, переменных и посто нных сопротивлений ь R, R и .The electronic chopper consists of a current transformer 1, included in the circuit of the secondary coil of the welding machine, semiconductor rectifier 2, electron tube triode 3, capacitor 4, control relay 5, variable and constant resistances R, R and.

При прохождении сварочного тока через вторичный виток сварочной машины в трансформаторе тока / индуктируетс  э.д.с., величина которой пропорциональна силе сварочного тока.When the welding current passes through the secondary turn of the welding machine in the current transformer, an emf is induced, the value of which is proportional to the strength of the welding current.

Напр жение, получаемое во вторичной обмотке трансформатора тока /, выпр мл етс  полупроводниковым выпр мителем 2 и подаетс  на анодный контур электронной лампы-триода 3.The voltage received in the secondary winding of the current transformer, is rectified by a semiconductor rectifier 2 and is applied to the anode circuit of the electron tube-triode 3.

Анод лампы-триода 3 присоединен к выпр мителю через включенные параллельно конденсатор 4 и управл ющее реле 5. Катушка реле зашунтирована переменным сопротивлением R, а контакты реле 5  вл ютс  контактами прерывател , коммутирующего первичную обмотку трансформатора сварочной мащины.The anode of the lamp-triode 3 is connected to the rectifier through parallel-connected capacitor 4 and control relay 5. The relay coil is bounded by variable resistance R, and the contacts of relay 5 are the contacts of the chopper switching the primary winding of the welding machine transformer.
