Description

Изобретение относитс  к обработке метал ,лов давлением, Известен способ шготовленн  изделий с фланцем из прутковой заготовки, включающий в себ  фасонную осадку, окончательную формовку флашда и формовку нижней части издели , а также обратное выдавливание полого злемента издели  1. Недостатки указанного способа - высока  трудоемкость процесса, невысока  производительность и ограниченна  номенклатура получаемых изделий, а также необходимость использовани  специального кузнечно-прессового оборудовани . Известен также способ изготовлени  издели типа стаканов с наружным утолщением у открытого торца, включающий в себ  штамповку листовой заготовки с формированием утолщени  и выдавливание 2. Недостатками такого сгюсоба  вл ютс  значительна  трудоемкость, невысока  производительность и ограниченна  номенклатура получае мых гэделий. Пель изобретени  - снижение трудоемкости, повышение производительности и расширение номенклатуры получаемых изделий, т.е. возможность получё1ш  изделий с различной конфигурацией поперечного сечени . Дл  достижени  этой цели штамповку производ т путем выт жки с утонением, осуществл емой с обратным выдавливанием за один переход. На чертеже изображена схема осу1цествлени  предлагаемого способа. В положении а показано положение пуансона в момент завершени  выт жки утолщени  у открытого торца. В положерши в показано положение пуансона в момент завершени  обратного выдавливани  избытка металла донной части издели . Ступенчата  составна  матрица 1 в верхней части имеет выточку 2 дл  установки заготовки , строго соосную с осью матрицы. л -бина выт жной части матрицы И больше на 2-3 мм высоты утолщени  у открытого торца. Переход от верхней выт жной зоны матрицы к зонгThe invention relates to the processing of metal, pressure fishing. A known method of manufacturing products with a flange from a bar stock, including a shaped draft, final molding of the flash and molding of the lower part of the product, as well as reverse extrusion of the hollow element of the product 1. The disadvantages of this method are the high complexity of the process. , low productivity and limited range of products, as well as the need to use special forging equipment. There is also known a method of manufacturing an article of the type of glasses with an outer thickening at the open end, which includes stamping the sheet stock with the formation of a bulge and squeezing 2. The disadvantages of such a bout are considerable labor intensity, low productivity and a limited range of obtained gadelii. Pel of the invention - reducing labor intensity, increasing productivity and expanding the range of products obtained, i.e. the ability to obtain products with different cross-sectional configurations. To achieve this goal, the stamping is produced by stretching with thinning, carried out with reverse extrusion in a single transition. The drawing shows the scheme of implementation of the proposed method. In position a, the position of the punch is shown at the time of completion of the stretching of the bulge at the open end. The position of the punch is shown at the time of completion of the reverse extrusion of the excess metal of the bottom part of the product. The step composite matrix 1 in the upper part has a recess 2 for placing the workpiece, which is strictly coaxial with the axis of the matrix. The bin of the stretch part of the matrix I is 2-3 mm longer than the height at the open end. Transition from the upper exhaust zone of the matrix to the zong
