Изобретение относитс к области станкостроени и общего машиностроени и может использоватьс дл размагничивани крепежных электромагнитных приспособлений,The invention relates to the field of machine tools and general engineering and can be used to demagnetize the mounting of electromagnetic devices,
В известных устройствах дл размагничивани электромагнитных приспособлений длительность и характер процесса размагничивани не завис т от степени загрузки приспособлени закрепл емыми издели ми от характеристик этих изделий (материала, формы и т.п.) ПЗ. При задании времени и характера размагничивани исход т из экстремальных условий его осуществлени . Это приводит к неоправданному увеличению времени размагничивани приспособлений при примененни многримпульсных устройств и к ухудшению качества размагничивани при использовании однопульсных размагничивающих устройств.In the known devices for demagnetization of electromagnetic devices, the duration and nature of the demagnetization process does not depend on the degree of loading of the device with fixed products on the characteristics of these products (material, shape, etc.) of the PP. When specifying the time and nature of demagnetization, it proceeds from the extreme conditions of its implementation. This leads to an unjustified increase in the time of demagnetization of devices with the use of multi-pulse devices and to a deterioration in the quality of demagnetization when using single-pulse demagnetization devices.
Изобретение устран ет указанные недостатки, использу известную св зьThe invention overcomes these drawbacks using a known connection.
между количеством и характеристиками закрепл емых с одной стороны и индуктивным сопротивлением приспособлений , а, следовательно, характером изменени ею тока с другой стороны. Это достигаетс за счет введени в устройство размагничивани блока регистрации изменени тока приспособлени и осуществлени св зи этого блока с блоком формировани размагничи10 вающих импульсов.between the quantity and characteristics of fixtures fixed on the one hand and the inductive impedance of devices, and, consequently, the nature of the current change on the other hand. This is achieved by introducing into the demagnetizing device a recording unit of the change in the current of the device and communicating this unit with the demagnetizing unit for forming pulses.
