Description

Изобретение относитс  к производству изделий (прутки, трубы, профили) из алюминиевых сплавов методом гор чего прессовани  и может быть использовано дл  смазки прессинструмента.The invention relates to the manufacture of products (rods, pipes, profiles) of aluminum alloys by hot pressing and can be used to lubricate a press tool.

Известна смазка, используема  при гор чем прессовании алю.миниевых сплавов, содержаща  в качестве основы нефт ное масло, например минеральное масло цилиндровое 52 (ГОСТ 6411-52), и до 20 вес. % графита марки ГМГ (ТУ 21-25-2-67).A known lubricant used in hot pressing of aluminum-aluminum alloys, containing petroleum oil as a base, for example, mineral cylinder oil 52 (GOST 6411-52), and up to 20 wt. % graphite brand HMG (TU 21-25-2-67).

Примен емые смазки не позвол ют увеличить скорость прессовани , так как в результате интенсификации процессов пластической деформации происходит разрушение смазочной пленки, что приводит к налипанию прессуемого металла на инструмент и резкому ухудшению качества поверхностей прессизделий .The lubricants used do not allow for an increase in the speed of pressing, since as a result of the intensification of plastic deformation processes, the lubricating film is destroyed, which leads to sticking of the pressed metal to the tool and a sharp deterioration in the quality of the press parts.

Цель изобретени  - увеличение скорости прессовани  - достигаетс  тем, что в состав смазки ввод т сернистый натрий при следующем соотношении между компонентами (вес. %):The purpose of the invention, an increase in the speed of pressing, is achieved by the fact that sodium sulphide is added to the lubricant composition in the following ratio between the components (wt.%):

Графит15-25Graphite15-25

Сернистый натрий5-7Sodium Sulfur 5-7

Нефт ное маслоДо 100Oil oil up to 100

При гор чем прессовании алюминиевых сплавов с использованием предлагаемой смазки (НПИ-В-2) в результате сильного действи  пластических деформаций, высоких температур и давлений на контактирующих поверхност х интенсифицируетс  протекание физико-химических процессов с образованием прочно св занной с поверхностью пленки, котора  предотвращает налипание на инструмент прессуемого металла, снижает коэффициент трени  и увеличивает скорость прессовани  изделий, а следовательно, и производительность оборудовани .During hot extrusion of aluminum alloys using the proposed lubricant (NPI-V-2), as a result of strong plastic deformations, high temperatures and pressures on the contacting surfaces, physical and chemical processes are intensified to form a film strongly attached to the surface, which prevents on the tool of the pressed metal, reduces the coefficient of friction and increases the speed of pressing of products, and consequently, the productivity of the equipment.

При изготовлении смазки нефт ное масло нагревают до 120-130 С и выдерживают 1,5-2 час нрн этой температуре дл  удалени  влаги, а затем добавл ют графит и обезвоженный сернистый натрий. Полученную смесь неремешивают до получени  однородной массы.In the manufacture of lubricants, the oil is heated to 120-130 ° C and held for 1.5-2 hours at this temperature to remove moisture, and then graphite and dried sodium sulphide are added. The resulting mixture is not stirred until a homogeneous mass is obtained.

При гор чем прессовании труб из алюминневого сплава Д 16 используют смазку, содержащую (%):During hot pressing of pipes made of aluminum alloy D 16, a lubricant containing (%) is used:

Масло цилиндровое 5280Cylinder oil 5280

Графит ГМГ15HMG15 graphite

Сернистый натрий обезвоженный5Dehydrated sodium sulfide5

Дл  оценки эффективности смазки НПП- В-2 по сравнению с известной сравннвают скорости истечени , велич1П Ы удельных давлеыий в раоочем цилиндре пресса и чистоту внутренних поверхностей труб в результате прессовани  слитков при установившемс  температурном режиме 300-315° С. Смазку нанос т на поверхность иглы с помощью кисти.In order to evaluate the effectiveness of the lubricant NPP-B-2 compared to the known one, the rates of outflow are greater than the specific pressure in the cylinder of the press and the cleanliness of the internal surfaces of the pipes as a result of pressing the ingots at a steady-state temperature range of 300-315 ° C. with a brush.

Установлено, что при использовании предлагаемой смазки усилие прессовани  в течение всего цикла снижаетс  на 5-10 кг/см, а скорость прессовани  увеличиваетс  в среднем на 9,5%.It has been established that when using the proposed lubricant, the pressing force during the whole cycle decreases by 5-10 kg / cm, and the pressing speed increases on average by 9.5%.

Предмет изобретени Subject invention

Смазка дл  гор чей обработки металлов на основе нефт ного масла и графита, отличающа с  тем, что, с целью увеличени  скорости прессовани , в состав смазки введен сернистый натрий при следующем соотношении между компонентами (вес. %):Lubricant for hot processing of metals based on petroleum oil and graphite, characterized in that, in order to increase the pressing speed, sodium sulphide is added to the lubricant composition in the following ratio between the components (wt.%):
