Изобретение относитс к технологии маиностроени и направлено на повышение онструктивной прочности изделий типа вал, работающих на кручение.The invention relates to the technology of machine building and is aimed at improving the onstructive strength of shaft-like products operating in torsion.
Известен способ термомеханической обработки (ТМО) изделий, включающий нагрев до температуры пластической деформации , закрутку и охлаждение |1|Известен также способ термомеханической обработки изделий, включающий нагрев, осуществл емый последовательно токами высокой частоты, путем непрерывного перемещени издели вдоль оси в процессе посто нного его кручени и охлаждени Р.A known method of thermomechanical treatment (TMO) of products, including heating to the temperature of plastic deformation, twisting and cooling | 1 | torsion and cooling R.
Недостатком известных технических рещений вл етс невозможность производить равномерную закрутку тех зон издели , которым необходимо придать повышенную конструктивную прочность при обработке изделий , с неравномернь1м сечением по длине. Кроме того, невозможно осуществл ть ТМО с программным регулированием периода закрутки по длине со знакопеременной закруткой по локальным зонам.A disadvantage of the known technical solutions is the inability to produce a uniform twist of those product areas that need to be given increased structural strength when machining products, with an uneven cross-section along the length. In addition, it is impossible to carry out a TMO with programmed adjustment of the spin period along the length with an alternating twist in local zones.
Цель изобретени - повышение качества обработки.The purpose of the invention is to improve the quality of processing.
Дл достижени поставленной цели кручение осуществл ют в зоне нагрева.To achieve this goal, torsion is carried out in the heating zone.
На чертеже изображена схема процесса.The drawing shows a process diagram.
Испытани провод т на изделии типа «вал, изготовленного из стали 38Х, днаметром 30мм и длиной 000мм.The tests were carried out on a product such as a shaft made of 38X steel, with a 30 mm diameter and a length of 000 mm.
Изделию I сообщают посто нный крут щий момент, установив, например в зажимные гидропатроиы 2 закручивающего устройства , локально разогревают до 1250°С поThe product I is given a constant torque, by installing, for example, in the clamping hydropatroy 2 swirling devices, locally heated to 1250 ° C by
всему радиальному сечению издели . Дл нагрева издели используют, например кольцевой закалочный индуктор 3. Затем зону нагрева непрерывно последовательно перемещают вдоль оси издели со скоростью 1,5м/сек в процессе посто нного кручени the entire radial section of the product. For heating the product, for example, an annular quenching inductor 3 is used. Then the heating zone is continuously sequentially moved along the axis of the product at a speed of 1.5 m / s during a constant torsion process.
издели . Период закрутки регулируют либо изменением угловой скорости вращени гидропатронов при посто нной скорости последовательного движени индуктора, либ( изменением скорости передвижени закалочного индуктора при посто нной угловой CKOpfKти вращени гидропатронов. Дл исключенн возможных деформаций, по вл ющихс в процессе закрутки, изделие одновременно раст гивают с усилием Р 0,25.products. The twist period is controlled by either changing the angular velocity of rotation of the hydraulic cartridges at a constant speed of the successive movement of the inductor, or by changing the speed of movement of the quenching inductor at a constant angular CKOpfK rotation of the hydraulic cartridges.
