Abstract
Изобретение относитс к области порошковой металлургии, в частности к конструкции пресс-форм дл прессовани материалов с высоким коэффициентом трени . Цель изобретени - повышение удобства эксплуатации и сокращение трудозатрат на изготовление пресс-формы. Цель достигаетс за счет того, что коэффициент трени обоймы и вставки друг о друга ниже, чем спрессованного брикета и вставки и, следовательно , последн легко выдавливаетс из обоймы вместе с брикетом. Дл этого вставка выполнена в виде кольца из упругой стальной полосы толщиной 0,003-0,005 и длиной 1,01 -1,05 длины окружности поперечного сечени полости обоймы. 1 ил. со о со 4:: со OiThe invention relates to the field of powder metallurgy, in particular to the design of molds for pressing materials with a high coefficient of friction. The purpose of the invention is to increase the convenience of operation and reduce labor costs for the manufacture of the mold. The goal is achieved due to the fact that the coefficient of friction of the yoke and the insertion of each other is lower than that of the compressed briquette and the yoke and, therefore, the latter is easily squeezed out of the yoke together with the briquette. For this, the insert is made in the form of a ring of an elastic steel strip with a thickness of 0.003-0.005 and a length of 1.01-1.05 of the circumference of the cross-section of the cavity of the cage. 1 il. co o co 4 :: co Oi
Description
Изобретение относитс к порошковой металлургии, в частности к конструкции пресс-форм дл прессовани материалов с высоким коэффициентом трени .The invention relates to powder metallurgy, in particular, to the design of molds for pressing materials with a high coefficient of friction.
Цель изобретени - повышение удобства эксплуатации и сокращение трудозатрат на изготовление пресс-формы.The purpose of the invention is to increase the convenience of operation and reduce labor costs for the manufacture of the mold.
На чертеже показан обший вид пресс- формы.The drawing shows a general view of the mold.
Пресс-форма содержит пуансоны 1 и 2, а также матрицу в виде кольцевой обоймы 3, и размещенной в ее цилиндрической полости 4 разъемной вставки 5. Последн выполнена в виде кольца из упругой стальной полосы толщиной 0,003-0,005 и длиной 1,01 -1,05 длины окружнности поперечного сечени полости 4.The mold contains punches 1 and 2, as well as a matrix in the form of an annular holder 3, and a detachable insert 5 placed in its cylindrical cavity 4. 05 circumference of the cross section of the cavity 4.
Пресс-форма работает следующим образом .The mold works as follows.
В полость вставки 5 на пуансон 2 засыпаетс порошок. Прессование производитс посредством приложени усили к пуансону 1.Powder is poured into the cavity of the insert 5 on the punch 2. The pressing is done by applying force to the punch 1.
После окончани процесса прессовани матрица устанавливаетс на упор (на чертеже не показан) и далее к одному из пуансонов прикладываетс усилие выталкивани . При этом, так как коэффициент трени обоймы и вставки друг о друга ниже, чем спрессованного брикета и вставки, то последн легко выдавливаетс из обоймы вместе с брикетом .After the extrusion process is completed, the die is placed on the anvil (not shown in the drawing) and then an ejection force is applied to one of the punches. In this case, since the coefficient of friction of the cage and the insert against each other is lower than that of the compressed briquette and the insert, the latter is easily squeezed out of the cage together with the briquette.
Технико-экономический эффект от внедрени изобретени обеспечиваетс повышением удобства в эксплуатации и сокращением трудозатрат при изготовлении пресс-формы.The technical and economic effect of the implementation of the invention is provided by an increase in ease of operation and a reduction in labor costs in the manufacture of the mold.
