[0002] Ring rolling machines are divided into two types: vertical and horizontal according to the form of the frame and the position of the ring. Most small and medium-sized ring rolling machines adopt an inclined vertical type for the convenience of operation, while large ring rolling machines mostly adopt a horizontal type for the convenience of translation and transmission. According to the process mode, ring rolling machines are divided into closed and open types. The closed type ring rolling machine puts the heated and punched blank on the core roller, and drives the blank to rotate by the inner edge of the rolling roller to achieve the thinning of the blank thickness and the expansion of the diameter. This process mode has been less used due to the limitations of the structure. The open type ring rolling machine puts the heated and punched blank on the core roller, and drives the blank to rotate by the outer edge of the rolling roller 1 to achieve the rolling forming of the thinning of the blank thickness and the expansion of the diameter. This process mode is more reasonable and applicable in terms of material input and output, the diameter of the rolling ring and the machine structure, so it is widely used.
