Problems solved by technology
[0006] With the first method, there are differences in the material structure of the forging and the weld, and the material structure of each forging manufactured in sections, which affects the overall performance of the forging; the release of welding stress will cause the forging to be produced during subsequent processing and use. large deformation
[0007] Adopting the second method will destroy the streamline integrity of the forging and reduce the overall performance of the forging; removing a large amount of material at the same time not only causes waste of resources, but also increases processing time and cost, resulting in long manufacturing cycle and poor economy

Embodiment Construction
[0029] The present invention will be further described below in conjunction with accompanying drawing:
[0030] A method for manufacturing a GH3536 alloy band flange bowl ring forging, comprising the following steps:
[0031] 1) Making a rectangular ring blank
[0032] Saw the GH3536 alloy bar according to the requirements, heat the sawed bar to 1140 ° C ~ 1160 ° C and keep it warm. Holes and reaming to obtain rectangular ring blanks;
[0033] 2) Making stepped ring blanks
[0034] Insert the long mandrel 4 into the inner hole of the rectangular ring blank, and place part of the rectangular ring blank on the lower anvil 3, and the press drives the upper anvil 2 to apply a pressure of 1000T to 3000T on the part of the rectangular ring blank placed on the lower anvil 3, At the same time, the manipulator rotates the rectangular ring blank. Under the extrusion action of the elongated mandrel 4 and the upper anvil 2, the inner diameter of the ring blank remains unchanged, the wa...

The invention relates to a method for manufacturing a GH3536 alloy flanged bowl-shaped ring forging. The beneficial effects of the present invention are as follows: 1) The integral forming of the tire mold can maintain the streamline integrity of the forging, the external dimensions are closer to the finished product, the margin removed by subsequent machining is greatly reduced, and the material is improved. The utilization rate shortens the processing cycle; 2) No welding is required, which ensures the uniformity of the internal material structure of the ring forging and avoids the deformation caused by the difference in material structure and stress release caused by welding.
Description
technical field [0001] The invention relates to the technical field of manufacturing special-shaped ring forgings, in particular to a method for manufacturing GH3536 alloy flanged bowl-shaped ring forgings. Background technique [0002] GH3536 alloy is a nickel-based high-temperature alloy with high iron content and solid solution strengthening of chromium and molybdenum. It has strong oxidation resistance and corrosion resistance, and has good cold and hot forming and welding performance. The working temperature can reach 1080°C. [0003] The GH3536 alloy flanged bowl ring forging is a commonly used part in the aviation field. Its shape is a bowl with a flange, and its inner and outer diameters are small, making it difficult to form. There are two existing manufacturing methods for GH3536 alloy flanged bowl ring forgings: [0004] 1) Forging in sections, and then welding each part to obtain the whole bowl-shaped ring forging; [0005] 2) Machining the rectangular ring wi...
