Claims (5)

1. Способ контроля качества отштампованной детали из ферромагнитных материалов неразрушающим методом, заключающийся в том, что измеряют амплитуду третьей гармоники тангенциально-составляющей ЭДС накладного датчика в критической точке по деформациям в двух взаимно перпендикулярных направлениях, отличающийся тем, что измеряют амплитуду третьей гармоники нормально-составляющей ЭДС накладного датчика в зоне утонения материала при деформациях, 3 - 4 мм от линии утонения, и по величине амплитуды третьей гармоники нормально-составляющей ЭДС накладного датчика судят о качестве детали и величине утонения.1. A method for controlling the quality of a stamped part from ferromagnetic materials by a non-destructive method, which consists in measuring the amplitude of the third harmonic of the tangential component of the EMF of the surface sensor at a critical point by deformations in two mutually perpendicular directions, characterized in that they measure the amplitude of the third harmonic of the normal component EMF of the surface-mounted sensor in the zone of thinning of the material during deformations, 3 - 4 mm from the thinning line, and in magnitude of the amplitude of the third harmonic of the normal component of the EMF the overhead sensor judges the quality of the part and the amount of thinning. 2. Способ по п.1, отличающийся тем, что отбирают бракованные детали с различной величиной утонения по 7 - 8 деталей для малой статистики. 2. The method according to claim 1, characterized in that the defective parts are selected with different sizes of thinning of 7 to 8 parts for small statistics. 3. Способ по пп.1 и 2, отличающийся тем, что отобранные детали испытывают на стенде на циклическую усталость (долговечность) до 200000 циклов. 3. The method according to PP.1 and 2, characterized in that the selected parts are tested on the stand for cyclic fatigue (durability) up to 200,000 cycles. 4. Способ по пп. 1 - 3, отличающийся тем, что выбирают детали, выдержавшие циклическую нагрузку, близкую к 200000 циклам, но за их пределами. 4. The method according to PP. 1 to 3, characterized in that they choose parts that withstand a cyclic load close to 200,000 cycles, but beyond. 5. Способ по пп.1 - 4, отличающийся тем, что все имеющиеся замеры по выбранным деталям, выдерживающие циклическую нагрузку 200000 циклов статически обрабатывают и назначают граничную величину амплитуды третьей гармоники для определения величины утонения и качества детали. 5. The method according to claims 1 to 4, characterized in that all available measurements on selected parts that withstand a cyclic load of 200,000 cycles are statically processed and a boundary value of the amplitude of the third harmonic is assigned to determine the amount of thinning and quality of the part.
