[0002] Nickel-based alloy refers to a type of alloy with comprehensive properties such as high strength and certain resistance to oxidation and corrosion at high temperatures of 650-1000°C. According to the main properties, it is further subdivided into nickel-based heat-resistant alloys, nickel-based corrosion-resistant alloys, nickel-based wear-resistant alloys, nickel-based precision alloys and nickel-based shape memory alloys. Metal processing refers to human production activities that process materials with metallic properties composed mainly of metal elements or metal elements, and nickel-based alloys need to be forged during the processing.

[0003] However, there are some problems in the forging process of existing nickel-based alloy shaft parts. It is not convenient to clamp nickel-based alloy shaft parts of different diameters during the forging process, which easily reduces the application scope of the device.

For example, some forging tools are for left and right impact forging, some forging tools are for front and back impact forging, and some forging tools are for up and down impact forging. Most of the existing clamping forging devices are only suitable for a single forging tool, which reduces the practicality of the device. In addition, sparks will be generated during the forging process of nickel-based alloy shaft parts, and it is not convenient to shield the sparks. Sparks may cause injuries. Summary of the invention
