Изобретение относитс  к способам обработки изделий из полимерных материалов и может быть использовано в различных отрасл х промышленности, например, при изготовлении проводов или кабелей с изол цией из пластмасс и резины.The invention relates to methods for treating products from polymeric materials and can be used in various industries, for example, in the manufacture of wires or cables with plastic and rubber insulation.

Известен способ обработки изделий из полимерного материала (резины) путем охлаждени  заготовок в жидком азоте и сн тие припуска режущим инструментом.A known method of treating products from a polymer material (rubber) by cooling the blanks in liquid nitrogen and removing the allowance with a cutting tool.

Однако известным способом нельз  получить изделие с высокой точностью, поскольку режущий инструмент последовательно подвод т к отдельным участкам заготовки, имеющим различную температуру. Кроме того, следует отметить, что при механической обработке изделий из полимерных материалов, нагретых до температур выше криогенных, не исключены токсичные выделени .However, it is not possible to obtain a product with high accuracy in a known manner, since the cutting tool is successively brought to separate parts of the workpiece having different temperatures. In addition, it should be noted that during the mechanical processing of products from polymeric materials heated to temperatures higher than cryogenic, toxic emissions are not excluded.

Цель изобретени - повысить точность обработки и исключить токсичные выделени .The purpose of the invention is to improve the processing accuracy and eliminate toxic secretions.

Дл  этого режущий инструмент подвод т только « участкам заготовки, имеющим одинаковую температуру, меньшую температуры стекловани  аморфной фазы полимера.For this purpose, the cutting tool is supplied only to the areas of the workpiece having the same temperature lower than the glass transition temperature of the amorphous polymer phase.

Чертеж по сн ет предлагаемый способ. Заготовку 1 с отдатчика 2 т говым устройством 3 прот ускают через криогенный сосуд 4 с криогенной жидкостью 5 со скоростью, обеспечивающей стеклование аморфной фазы, обрабатывают режущим инструментом 6 с приводом 7 и принимают на приемки 8.The drawing explains the proposed method. The billet 1 from the transmitter 2 with a traction device 3 is extruded through a cryogenic vessel 4 with a cryogenic liquid 5 at a rate that ensures the vitrification of the amorphous phase, is treated with a cutting tool 6 with a drive 7 and is accepted for acceptance 8.

Регулиру  скорость движени  заготовки, можно измен ть температуру и степень усадки участка заготовки перед режущим инструментом , а следовательно, толщину снимаемого припуска и диаметр обработанной заготовки при использовании одного и того же инструмента без перенастройки последнего. Регулировка температуры путем изменени  скорости должна производитьс  в таких пределах , чтобы полимер оставалс  в стеклообразном состо нии.By adjusting the speed of the workpiece, it is possible to change the temperature and the degree of shrinkage of the section of the workpiece in front of the cutting tool, and consequently, the thickness of the allowance being removed and the diameter of the finished workpiece when using the same tool without reconfiguring the latter. Temperature control by varying the speed must be made within such limits that the polymer remains in a glassy state.

Предмет изобретени Subject invention

Способ обработки изделий из термопластичных материалов, например кабелей с пластмассовой изол цией, включающий охлаждение заготовки до криогенных температур , например, жидким азотом, и сн тие припуска режущим инструментом, отличающийс  тем, что. с целью повышени  точности обработки, исключени  токсичных выделений , режущий инструмент подвод т к участкам заготовки, имеющим одинаковую температуру , меньшую температуры стекловани  аморфной фазы полимера.A method of treating products made from thermoplastic materials, for example cables with plastic insulation, includes cooling the workpiece to cryogenic temperatures, such as liquid nitrogen, and removing the seam allowance with a cutting tool, characterized in that. in order to increase the machining accuracy, eliminate toxic excretions, the cutting tool is brought to workpieces having the same temperature less than the glass transition temperature of the amorphous polymer phase.
