Manufacturing method of high-temperature alloy ring forge piece shaped like Chinese character'chang '

The invention discloses a manufacturing method of a high-temperature alloy ring forge piece shaped like a Chinese character'chang '. The manufacturing method comprises the steps of blanking, upsetting, punching, pre-rolling, reducing preforming, preforming a large end, forming a small end and the like. Compared with the prior art, the product is formed in a segmented mode, the scheme is simple, the production period is shortened, and the requirement of overall deformation for the equipment capacity is lowered. According to the method, the H2 part with the minimum wall thickness in the figure 1 is obtained through reducing preforming, then the H1 part and the H3 part are obtained through material gathering at the two ends, the product is divided into three parts to be formed through the method, the requirement of overall deformation for the equipment capacity is lowered, and each part can be formed only through one working procedure. 本发明公开了一种高温合金厂字形环锻件制造方法，包括下料、镦粗、冲孔、预轧、缩径预成型、预成型大端、成型小端等步骤。与现有技术相比，本发明将产品分段进行成型
