Drawing forming device and method of rotary part

Abstract

The invention relates to the technical field of metal material machining, in particular to a drawing forcing device and method of a rotary part. The device comprises an upper combined die, a male die, a female die, a female die frame, a lower die, a guide column, a guide sleeve, an ejection rod and an ejection plate. The male die is fixedly connected with the lower end of a lower combined die, the female die is arranged in the female die frame, the female die is fixedly connected with the upper end of the lower die, the lower end of the ejection rod is connected with the ejection plate, and the upper end of the ejection rod penetrates the lower die to be fixedly connected with the female die frame; and the female die is arranged below the male die, and the axis of the male die coincides with the axis of the female die. One end of the guide sleeve is fixedly connected with the upper combined die, and fixedly connected with the lower die, and the other end of the guide column is inserted in the other end of the guide sleeve in a penetrating manner. The method comprises blank manufacturing, blank positioning, blank drawing, blank annealing, die pressure maintaining and mechanical machining. According to the drawing forcing device and method of the rotary part, the problem that in the drawing process of the rotary part, ripping, wrinkling and scrapping are prone to appearing is solved.

Description

technical field [0001] The invention relates to the technical field of metal material processing and forming, in particular to a method and device for deep drawing and forming of revolving body parts. Background technique [0002] Pressure vessels, as airtight equipment carrying a certain pressure, have strict requirements on airtightness and pressure resistance. Common pressure vessels include metal pressure vessels, non-metal pressure vessels, and metal-lined composite pressure vessels. The common structure of the metal-lined composite material pressure vessel is a thin-walled rotary body. The thick-walled small-volume structure in the thin-walled rotary body is mainly formed by integral machining of half parts and then welded. The thin-walled large-volume structure is mainly formed by spinning or A method of deep drawing and then welding. [0003] Stainless steel has become a common material for metal linings due to its excellent corrosion resistance, high temperature ox...
