Description

Изобретение относитс к области обработки металлов давлением, в частности к способам формовки цилиндрических изделий отбортовкой .The invention relates to the field of metal forming, in particular, to methods for forming cylindrical articles by flanging.
В осповном авт. св. № 397250 описан способ формовки цилиндрических заготовок обкаткой на оправке, например, роликом с местным индукционным нагревом заготовки, согласно которому между заготовкой и оправкой помещают кольцо из материала заготовки.In ostivnom aut. St. No. 397250 described a method of forming cylindrical blanks by running on a mandrel, for example, a roller with local induction heating of the blank, according to which a ring of blank material is placed between the blank and the mandrel.
Однако при осуществлении такого способа наблюдаетс повыщенный отвод тепла от поверхности заготовки через кольцо на массивную оправку, в результате чего снижаетс качество издели и повыщаетс расход металла на дополнительные припуски под механическую обработку.However, with this method, there is an increased heat removal from the surface of the workpiece through the ring to the massive mandrel, as a result of which the quality of the product is reduced and the metal consumption for additional machining allowances increases.
С целью повыщепи коэффициента использовани металла и улучщепи .качества изделий по предлагаемому способу между промежуточным кольцом и оправкой помещают слой теплоизол ционного материала, например стеклоткани.In order to increase the utilization rate of the metal and improve the quality of the products according to the proposed method, a layer of heat-insulating material, for example glass fabric, is placed between the intermediate ring and the mandrel.
Предлагаемый способ иллюстрируетс чертежом .The proposed method is illustrated in the drawing.
Между оправкой 1 и заготовкой 2, например кольцевой оболочкой, помещают промежуточное кольцо 3 из того же материала, что и заготовка , а между промежуточным кольцом и оправкой располагают теплоизол ционный слой 4, например стеклоткани или асбеста, толщиной 1-2 мм. Индуктором 5 нагревают формуемую зону до температуры гор чей деформации и перемещением давильного ролпка б с одновременным вращением заготовки, зажатой в планшайбе станка, производ т формовку фланца отбортовкой.Between the mandrel 1 and the workpiece 2, for example an annular casing, an intermediate ring 3 of the same material as the workpiece is placed, and a heat insulating layer 4, for example fiberglass or asbestos, is placed 1-2 mm thick between the intermediate ring and the mandrel. Inductor 5 heats the formable zone to the temperature of hot deformation and by moving the pressing roller b with simultaneous rotation of the workpiece clamped in the machine faceplate, the flange is formed by flanging.
