Description
Изобретение относитс к области машиностроени и может быть использовано при изготовлении крупногаба- ритной арматуры, например задвижек и клапанов, а также фитингов трубопроводов высокого давлени .The invention relates to the field of mechanical engineering and can be used in the manufacture of large-sized reinforcement, such as valves and valves, as well as fittings for high-pressure pipelines.
Известны способы изготовлени корпусов арматуры трубопроводов путем штс№1повки в несколько переходов.There are known methods for manufacturing pipe fittings housings by means of a piece of plastic in several transitions.
Цель изобретени - улучшение условий распределени волокон в корпусе арматуры трубопроводов.The purpose of the invention is to improve the distribution conditions of the fibers in the body of the pipeline fittings.
Это достигаетс тем, что на первых переходах получают заготовку куполообразной формы с центральным наружньш патрубком, формование которого осуществл ют с набором металла, а на последующих переходах формуют внутренний патрубок, Перераспредел металл по объему издели , дл чего производ т разделку отверстий патрубка и его осадку.This is achieved by the fact that at the first transitions a dome-shaped billet with a central outer pipe is formed, which is molded with a set of metal, and at subsequent transitions an internal pipe is molded.
На чертеже показаны последовательные стадии изготовлени патрубка предложенньа способом.The drawing shows the successive stages of the manufacture of the pipe by the proposed method.
Круглую заготовку вырезают из листа (см. чертеж, поз.а), выт гивают через ко-льцевую матрицу куполообразную заготовку (см. поз.б), в которой растачивают (или сверл т) центральное отверстие, и подрезают кромку (см. поз.б), после этого производ т продольный обжим куполообразной заготовки, совмещенной с отбортовкой отверсти (см.поз.в), и местной объемной штамповкой придают патрубку окончательную фот иу fcM- поз.г).A round billet is cut out of the sheet (see drawing, pos. A), a dome-shaped billet (see pos. B) is pulled out through the die matrix, in which the central hole is bored (or drilled), and the edge is cut (see pos. .b), then a longitudinal crimping of the dome-shaped billet combined with the flanging of the hole (see pos. c) and local volumetric stamping is done to give the nozzle a final photo fcM-pos.g).
Аналогично формуют куполообразные элементы и из трубных заготовок.Similarly molded dome-shaped elements and tubular blanks.
