Description
Устройство содержит матрицу 1, верхний и нижний пуансоны 2 и 3 соответственно , систему 4 соленоидов, центральный знак 5 и магнитопроводы 6.The device contains a matrix 1, the upper and lower punches 2 and 3, respectively, a system of 4 solenoids, a central sign 5 and magnetic circuits 6.
Количество соленоидов, необходимых дл создани равномерного радиально направленного текстурующего пол , должно быть таким, чтобы потоки, создаваемые р дом сто щими соленоидами, перекрывались на 4-6°С.The number of solenoids necessary to create a uniform radially directed texture field should be such that the flows created by the nearby solenoids overlap by 4-6 ° C.
Устройство работает следующим образом .The device works as follows.
В рабочую полость матрицы 1 загружают порцию порошка прессуемого материала, затем на знак 5 устанавливают верхний пуансон 2, после чего монтируетс верхн часть магнитопровода 6.A portion of the powder of the material to be pressed is loaded into the working cavity of the matrix 1, then the top punch 2 is installed on the sign 5, after which the upper part of the magnetic circuit 6 is mounted.
С помощью системы 4 соленоидов, расположенных симметрично и включенных однопол рно на матрицу, создают равномерное радиально направленное текстурующее магнитное поле в рабочем зазоре матрицы, а магнитопроводы замыкают магнитные потоки встречно, на центральный знак. Магнитный поток, проход по магнитопроводам 6, ориентирует прессуемый порошок в рабочей полости /матрицы перпендикул рно цилиндрическим поверхност м рабочей полости равномерно по высоте порошка. К верхнему и нижнему пуансонам 2 и 3 прикладывают необходимое усилие прессований . Магнитное поле снимаетс после полного завершени процесса прессовани . Спрессованное изделие выталкиваетс из матрицы 1 нижним пуансоном 3 при отведении вверх пуансона 2 и верхней части магнитопровода 6.Using a system of 4 solenoids, located symmetrically and turned on unipolarly on the matrix, they create a uniform radially directed texture magnetic field in the working gap of the matrix, and the magnetic circuits close the magnetic flux in the opposite direction to the central sign. The magnetic flux, the passage along the magnetic cores 6, orients the pressed powder in the working cavity / matrix perpendicularly to the cylindrical surfaces of the working cavity evenly along the height of the powder. The required pressing force is applied to the upper and lower punches 2 and 3. The magnetic field is removed after the complete extrusion process. The compressed product is pushed out of the matrix 1 by the lower punch 3 while leading up the punch 2 and the upper part of the magnetic circuit 6.
Предложенное устройство позвол ет изготавливать цельные .радиально-анизотропные кольцевые посто нные магниты с магнитной энергией 60-64 кДж/м, позвол ет повысить равномерность распределени магнитных свойств по высоте получаемых магнитов и уровень магнитных свойств на 10- 15%. The proposed device makes it possible to manufacture one-piece radially-anisotropic ring permanent magnets with magnetic energy of 60-64 kJ / m, improves the uniformity of distribution of magnetic properties along the height of the resulting magnets and the level of magnetic properties by 10-15%.
