Abstract

A cooling-lubricating paste comprises water, a bentonite having a grain size of at most 70 microns, e.g., 5.0 to 30.0% by weight and optionally an oil conventionally used in combination with water-based cooling-lubricating liquids, in a conventional quality and amount and optionally further additives, preferably improving lubrication. The properties of cooling-lubricating liquids conventionally employed during shaping and cutting metals and other materials are improved by admixing 0.1 to 20% by weight of additives liable to precipitation from the above liquids, e.g. disinfectants and aroma materials with 30.0 to 80.0% by wt. of water, 5.0 to 30.0% by wt. of the above bentonite and 30.0-50.0% by wt. of the above oil.

Description

Изобретение относитс  к смазочно- охлаждающим композици м дл  холодной обработки металлов, в частности, используемым при глубокой выт жке металлов и в процессах резани , т.е. при обработке металлов со сн тием и без сн ти  стружки.This invention relates to coolant-cooling compositions for cold working of metals, in particular, used in the deep drawing of metals and in cutting processes, i.e. when processing metals with and without shavings.

Целью изобретени   вл етс  повышение стойкости инструмента.The aim of the invention is to increase tool life.

Дл  приготовлени  смазочно-охлаж- дающей композиции используют фракцию бентонита с размером частиц от менее 70 до 1 мкм,For the preparation of a lubricant-cooling composition, a fraction of bentonite with a particle size of less than 70 microns is used.

Бентонит ввиду своей способности к набуханию в жидкост х на водной основе может образовывать пасту, котора  эффективна при применении в качестве охлаждаюцей и смазочной композиции при высоких скорост х обработки . Качество и гомогенность пасты зависит от размера частиц бентонита. Если измельченпа  Г 1;зсса бентонита имеет частички размером более 70 мкм, то не обеспечиваетс  необходима  гладка  поверхность при обработке металлов из-за плохой способности к набуханию слишком крупных частичек. Размер частиц 1 мкм - это минимально допустимый размер частиц, обеспечивающий требуемую скорость инструмента.Due to their ability to swell in water based fluids, bentonite can form a paste that is effective when used as a cooling and lubricating composition at high processing speeds. The quality and homogeneity of the paste depends on the size of the particles of bentonite. If the crushed carbon dioxide of the bentonite has particles larger than 70 microns in size, then a smooth surface is not ensured when processing metals because of the poor ability to swell too large particles. The particle size of 1 micron is the minimum allowable particle size that provides the required tool speed.

Дл  приготовлени  смазочно-охлаж- дающей композиции используют также минеральное масло (малов зкое) или его смесь с растительным маслом или полидиметилсилоксановую жидкость (ПМС). В качестве смеси минерального и растительного масел используют продукт К-22, представл ющий собой смесь 84,0 мас.% малов зкого минерального масла с 10 мас.% ра)1сового.Mineral oil (low viscosity) or its mixture with vegetable oil or polydimethylsiloxane fluid (PMS) is also used to prepare the lubricant-cooling composition. As a mixture of mineral and vegetable oils, the product K-22 is used, which is a mixture of 84.0% by weight of low-viscosity mineral oil with 10% by weight of ra) 1 s.

Дл  повышени  смазочных свойств смаэочно-охлаждающей композиции целесообразно в ее состав вводить стеа- рат кальци  и/или стеарат цинка в количестве 1-10 мас.%.To increase the lubricating properties of the cooling-cooling composition, it is advisable to introduce calcium stearate and / or zinc stearate in its amount in an amount of 1-10 wt.%.

Смазочно-охлаждающую композицию готов т либо путем одновременного перемещени  всех комг,онентов (в этом случае целесообразно использовать вращающуюс  лопастную мешалку с 1АОО об/мин), либо добавл   бентонит в водомасл ную эмульсию. При этом образуетс  однородна  паста без перемешивани , так как бентонит обладает значительной водопоглощающей спо- собностыо.The cooling lubricant composition is prepared either by simultaneously moving all comgs, onents (in this case it is advisable to use a rotating paddle mixer with 1AOO rpm), or by adding bentonite to the water-oil emulsion. This forms a homogeneous paste without mixing, since bentonite has a significant water-absorbing capacity.

Составы приготовленных смазочно- охлаждающих композиций приведены в таблице.The compositions of the prepared coolant compositions are given in the table.

Составы смазочных композиций 1-6 испытывают в процессе глубокой выт жки стальной пластины толщиной 2 мм. Необходимо изготовить деталь в форме стакана с диаметром 70 мм и высотой 40 мм. Дл  прессовани  примен етс  скорость 0,1 мм/с.The compositions of lubricating compositions 1-6 are tested in the process of deep drawing of a steel plate 2 mm thick. It is necessary to make a piece in the form of a glass with a diameter of 70 mm and a height of 40 mm. A speed of 0.1 mm / s is used for pressing.

В (Случае применени  известной смазочной композиции, представл ющей собой эмульсию нефт ного масла в во- да, содержащую э -гулъга тор, поверхность стальной пластины перед глубокой выт жкой необходимо фосфатиро- вать, чтобы предотвратить обламывание пластины, образование складок на поверхности издели , а также неравномерность толщины получаемых стенокIn (The case of application of a known lubricant composition, which is an emulsion of petroleum oil into water containing e-gas, the surface of the steel plate must be phosphated before deep drawing to prevent the plate from breaking, also uneven thickness of the resulting walls

С использованием составов 1-6 пластину подвергают глубокой иыт жке без предварительного фосфатировани  Поверхности. При этом получают стакан с равномерной толщиной стенок и гладкой поверхностью. Причем добавка стеаратов кальци  и цинка повьшает смазочные свойства композиции, каче- ство поперхности издели  при этом заметно улучшаетс . IUsing compositions 1-6, the plate is subjected to deep testing without prior phosphating of the surface. You get a glass with a uniform wall thickness and a smooth surface. Moreover, the addition of calcium stearates and zinc increases the lubricating properties of the composition, and the quality of the surface of the product is noticeably improved. I

Составы смазочно-охлаждающих композиций 7-12 испытывают при вихре- вой нарезке сферической (круглой) резьбы инструментом из твердого сплава при скорости резани  300 м/мин и вращении предмета 5 об/мин.The compositions of coolant lubricants 7-12 are tested with a vortex cutting of a spherical (round) thread with a hard metal tool at a cutting speed of 300 m / min and a rotation of the object at 5 rpm.

Резьба имеет следующие параметры: шаг 20 мм, длина 190 мм, наружный диаметр 284 мм, глубина 2,6 мм, ширина круглой резьбы - диаметр 7 мм; характеристика материала - BCMol, шероховатость обработанной поверхности 2,5 мкм.The thread has the following parameters: the pitch is 20 mm, the length is 190 mm, the outer diameter is 284 mm, the depth is 2.6 mm, the width of the round thread is 7 mm; material characteristics - BCMol, the surface roughness of 2.5 microns.

При применении предлагаемых составов срок службы инструмента достигает 180 мин и при этом обеспечиваетс  получение 13100 - 13200 нарезок, в то врем  как дл  известного состава количество получаемых нарезок не превышает 8400.When using the proposed formulations, the tool life reaches 180 minutes and at the same time 13100 to 13200 cuts are obtained, while for a known composition the number of cuts obtained does not exceed 8400.

Эффективность действи  смазочно- охлаждающих композиций оцениваетс  при обработке материалов более высокой твердости. Дл  этого составы 13 - 16 испытывают при вихревом нарезании резьбы при тех же параметрах обработки, что и составы 7 - 12. Трапецеидальна  резьба имеет следующие характеристики: щаг 12 мм, высота 6 мм, длина 1200 мм, наружный диаметр 50 мм; материал С60, шероховатость поверхности 2,5 мкм.The effectiveness of the cooling lubricant compositions is evaluated when processing materials of higher hardness. For this, compositions 13 to 16 are subjected to swirling threading with the same machining parameters as compounds 7 to 12. Trapezoidal threads have the following characteristics: schag 12 mm, height 6 mm, length 1200 mm, outer diameter 50 mm; C60 material, surface roughness 2.5 microns.

Как показывают результаты испытаний применение состава композиции 15 приводит к увеличению срока службы инструмента до 165 мин; добавление стеарата кальци  1 - 10 мас.% (составы 14 и 15) увеличивает срок службы инструмента до 185 мин; снижение концентрации бентонита до 10 мас,% (16) несколько снижает стойкость инструмента до 150 - 160 мин по сравнению с составами 14 и 15, однако сохран ет ее на достаточно высоком уровне.As shown by the test results, the use of the composition of composition 15 leads to an increase in the service life of the tool to 165 minutes; the addition of calcium stearate 1 - 10 wt.% (compounds 14 and 15) increases the service life of the tool to 185 minutes; Reducing the concentration of bentonite to 10 wt.% (16) slightly reduces the tool life to 150-160 minutes as compared with compounds 14 and 15, however, it remains at a sufficiently high level.
