Description

(54) СПОСОБ КОНТРОЛЯ КАЧЕСТВА ИЗГОТОВЛЕНИЯ СЕГМЕНТОВ АКТИВНОЙ СТАЛИ СТАТОРОВ ЭЛЕКТРИЧЕСКИХ(54) METHOD FOR MONITORING THE QUALITY OF MANUFACTURING THE SEGMENTS OF ACTIVE STEEL ELECTRIC STATORS

МАШИНCARS

.. ; fi-iiff f А Г ., Контроль осучюстБл етс  следующим обр аом. Листы электротехнической стали поступают на штампы, прохсад т операции гратосьема и лакирсФки. Готовые сегменты по- .даютс  в контрольный станок и проход т между врашаюшимис  датчиками. Сигналы от датчиков поступают в электронный .блок который обрабатывает полученную информа ,цию, сравнивает ее с установкой и выдает команду устройству разделени  сегментсв на годные и,брак. Условием годности  вл етс  непревыше ние сигнала, полученного при контроле сегм та, относительно уставки, котора  вводитс  в электронно-аналитический блок на ос- Ковании технологических норм. Одновременно с процессом ра1збракс ки ведетс  счет бракованных сегментов раздельно по двум каналам, полученные показа ни  используютс  дл  корректировки штам повки, гратосъема, с одной стороны, и режима лакировальной машины, с другой. Внедрение изобретени , согласно утверж денному .расчету, составит экономию 65,0 тыс. руб. в год...; fi-iiff f A G., The control is affected by the following procedure. Sheets of electrical steel are supplied to the dies, and the gratchem and lacqueFer operation is taken. The finished segments appear in the control machine and pass between the sensors. The signals from the sensors are sent to an electronic block that processes the information received, compares it with the installation, and issues a command to the device for dividing the segment into suitable and defective. The validity condition is the non-exceedance of the signal obtained by monitoring the segment with respect to the setpoint, which is inserted into the electronic analytical unit on the installation of technological standards. Simultaneously with the process of scrubbing, the counting of defective segments is carried out separately through two channels, the results obtained are used to adjust the straightening strain, grab removal, on the one hand, and the coating machine mode, on the other. The implementation of the invention, according to the approved calculation, will amount to a saving of 65.0 thousand rubles. in year.
