Description

Известны приборы дл  записи разрывных диаграмм на разрывных машинах, например ма тниковых динамометрах, с применением электрической схемы, в которую включены трансформатор переменного тока , выпр митель, делитель напр жени  и записываюш.ее устройство. Однако в таких приборах нет автоматической записи.Instruments are known for recording discontinuous diagrams on discontinuous machines, such as a mapping dynamometer, using an electrical circuit in which an AC transformer, rectifier, voltage divider and recording device are included. However, in such devices there is no automatic recording.

Описываемый прибор дл  более полной автоматизации записи, а также дл  использовани  прибора на разрывных машинах различной конструкции снабжен реостатным датчиком, движок которого установлен на оси ма тника. При повороте этой оси движок перемешаетс  по реохорду, измен   сопротивление между клеммами датчика, импульсы которого передаютс  электровно-занисывающему устройству с плоской ленточной диаграммой.The described device for more complete automation of the recording, as well as for using the device on tensile machines of various designs, is equipped with a rheostat sensor, the slider of which is mounted on the axis of the continuous body. When this axis is rotated, the slider is mixed along the reichord, changing the resistance between the terminals of the sensor, the pulses of which are transmitted to an electronic spreading device with a flat band diagram.

На фиг. 1 изображена схема прибора; на фиг. 2 - ось ма тника с датчиком.FIG. 1 shows a diagram of the device; in fig. 2 - axis of the tandem with the sensor.

Прибор дл  записи разрывных диаграмм на разрывных машинах состоит из корпуса, реостатного датчика /, движок 2 которого установлен на оси 3 ма тникового динамометра, трансформатора 4, полупроводникового выпр мител  5, стабилизатора 6, делител  7 напр жени  и электронио-записываюшего устройства 8.A device for recording discontinuous diagrams on discontinuous machines consists of a housing, a rheostat sensor /, the slider 2 of which is installed on the axis 3 of the main dynamometer, the transformer 4, the semiconductor rectifier 5, the stabilizer 6, the voltage divider 7 and the electron-recording device 8.

При нроведении испытаний в момент разрыва образца ось 3 динамометра вместе с указателем 9 и движком 2 датчика / поворачиваетс  на некоторый угол, движок 2 скользит по реохорду 10, измен   сопротивление между клеммами // и 12 датчика /, к которым подаетс  напр жение от трансформатора 4 через выпр митель 5, стабилизатор 6 и делитель 7. При помоши последнего напр жение довод т до нужной величины в зависимости от сопротивлени  датчика / и тарировки прибора.When testing is carried out at the moment of sample rupture, the axis 3 of the dynamometer together with the pointer 9 and the slider 2 of the sensor / turns through a certain angle, the slider 2 slides along the rheochord 10, changing the resistance between the terminals // and 12 of the sensor / to which the voltage from the transformer 4 through rectifier 5, stabilizer 6 and divider 7. With the aid of the latter, the voltage is adjusted to the required value depending on the resistance of the sensor / and the calibration of the device.

Каждому разрывному усилию соответствует свой угол поворота оси 3 и, следовательно, определенное сопротивление между клеммам;1Each breaking strength corresponds to its angle of rotation of axis 3 and, therefore, a certain resistance between the terminals; 1
