(54) СПОСОБ СКАЛЬПИРОВАНИЯ ЗАГОТОВОК(54) METHOD OF CLIPPING PREPARATIONS
1one
Изобретение относитс к обработке металлов давлением и может быть использовано при производстве заготовок с очищенной поверхностью и точными размерами.The invention relates to the processing of metals by pressure and can be used in the manufacture of blanks with a cleaned surface and exact dimensions.
Известен способ скальпировани заготовок сн тием стружки в матрице по всему периметру заготовки 1.There is a known method for scalping blanks to remove chips in the matrix along the entire perimeter of the blank 1.
Однако, данный способ характеризуетс недостаточно высоким качеством поверхности заготовки, так как при скальпировании периодически образуетс нарост на рабочих поверхност х режущего инструмента за счет сухого трени в зоне резани ; низкой стойкостью инструмента, также св занной с наличием сухого трени и высоких удельных давлений на кромках матрицы, что приводит к ее быстрому износу. Только при переходе к полной смазке износ при трении становитс незначительным.However, this method is characterized by an insufficiently high surface quality of the workpiece, since during scalping a build-up periodically forms on the working surfaces of the cutting tool due to dry friction in the cutting zone; low tool life, also associated with the presence of dry friction and high specific pressures at the edges of the die, which leads to its rapid wear. Only when moving to full lubrication does friction wear become insignificant.
Цель изобретени - повыщение качества поверхности заготовки и стойкости инструмента .The purpose of the invention is to increase the surface quality of the workpiece and tool life.
Поставленна цель достигаетс тем, что при сн тии стружки производ т гидростатическое противодавление смазочной среды с одновременным приложением к матрице ультразвуковых колебаний.This goal is achieved by the fact that when the chips are removed, a hydrostatic counter-pressure of the lubricating medium is produced with simultaneous application of ultrasonic vibrations to the array.
На чертеже приведена схема, по сн юща предлагаемый способ.The drawing is a diagram explaining the proposed method.
Заготовку 1 выдавливают в закрытый контейнер 2 с матрицей 3, котора расположена в пучности амплитуды смещений сто чей ультразвуковой волны 4. В контейнере 2 находитс смазка 5. При выдавливании заготовки в контейнер срез осуществл етс при гидростатическом противодавлении смазочной среды. Вследствие наличи зазора , который периодически возникает под действием ультразвуковых колебаний, срезае10 мый слой изолируетс от поверхности инструмента и поверхности заготовки. Дл поддержани посто нного давлени в контейнере 2 установлен клапан.The billet 1 is extruded into a closed container 2 with a matrix 3, which is located at the antinodes of the displacement amplitude of the standing ultrasonic wave 4. The container 2 contains lubricant 5. When extruding the billet into the container, the slice is made under hydrostatic counterpressure of the lubricant medium. Due to the presence of a gap, which periodically occurs under the action of ultrasonic vibrations, the shear layer is isolated from the tool surface and the surface of the workpiece. A valve is installed in the container 2 to maintain a constant pressure.
Таким образом, ликвидируетс предпо15 сылка образовани нароста на режущемThus, the prerequisite for the formation of growth on the cutting
инструменте за счет замены сухого трени жидкостным, при котором смазочный слой, выдавливаемый из контейнера, распредел етс равномерно по периметру и перемещаетс под давлением против направлени движени металла, что ведет к улучшению качества поверхности заготовки и увеличению стойкости режущей кромки матрицы.the tool due to the replacement of dry friction with liquid, in which the lubricating layer squeezed out of the container is distributed evenly around the perimeter and moves under pressure against the direction of metal movement, which leads to an improvement in the surface quality of the workpiece and an increase in durability of the cutting edge of the die.
