Description

/ , , :, - I . : . Изобретение относитс  к области механической обработки резанием с подогревом ... Известен способ механической обработки с подогревом, согласно которому на поверхности резани  с помрЩЫр плазменной струи выполн етс  канавка, макс мальна  глубина которой расположена вблизи линии пересечени  обработанной поверхности с поверхностью резани  I Однако указанный способ не позвол ет обрабатывать наплавленные поверхности, поскольку поверхность резани  имеет малую ширину и разместить на ней канавку с помощью плазмотрона невозможйо. Кроме того, известный способ не эф фективён при обработке деталей, полученных центробежным литьем, у которых в поверхностном слое имеютс  включени  кварцевого песка и нагрев поверхностного сло  даже до высоких температур не измен ет его абразивных свойств. Предлагаемый способ позвол ет осуществл ть обработку наплавленных поверхностей с мал:ой шириной поверхности резани , а деталей, полученных центробежным литьем, имеющих в поверхностном слое включени  кварцевого песка. Цель изобретени  - расширение техно логичесисих возможностей способа плазменно-механйчёской . обработки. С этой целью струей плазмотрона удал етс  часть Припуска, прилегающа  к необработанной поверхности, при этом ширина поверхности резани , образуема  резцом, составл ет не менее 1 мм, а глубина прогрева необработанной поверхностИ в направлений подачи превышает величину подачи не менее, чем в 2 раза. На чертеже представлена схема реализации предложенного способа. С поверхности обрабатываемой детали 1 с помощью плазмотрона удал етс  часть припуска 2, прилегающа  к не обработанной поверхности. Ширина поверхности резани  С,, образуема  резцом 3, составл ет не менее 1 мм. Глубина прогрейа S. необработан)аой поверхности в/,,:, - i. :. The invention relates to the field of machining cutting with heating ... There is a known method of heating machining, according to which a groove is made on the cutting surface with the plasma jet, the maximum depth of which is located near the line of intersection of the machined surface with the cutting surface I allows you to process the weld surface, because the cutting surface has a small width and to place a groove on it using a plasma torch is impossible. In addition, the known method is not effective when machining parts obtained by centrifugal casting, in which there are inclusions of quartz sand in the surface layer and heating the surface layer even to high temperatures does not change its abrasive properties. The proposed method allows the treatment of the deposited surfaces with a small width of the cutting surface, and centrifugal casting parts that have quartz sand included in the surface layer. The purpose of the invention is the expansion of the technological capabilities of the plasma-mechanic method. processing. For this purpose, a part of the Allowance is removed by a jet of the plasma torch adjacent to the untreated surface, while the width of the cutting surface formed by the cutter is at least 1 mm, and the warming depth of the untreated surface in the flow directions exceeds the feed rate not less than 2 times. The drawing shows the implementation of the proposed method. From the surface of the workpiece 1 using a plasma torch removes part of the allowance 2, adjacent to the untreated surface. The width of the cutting surface C ,, formed by the cutter 3 is at least 1 mm. Warm-up depth S. Unprocessed)

направлении подачи превышает величину подачи S не менее, чем в 2 раза (6 2S),the feed direction exceeds the feed rate S at least 2 times (6 2S),
