Embodiment 1
[0027] This embodiment provides a forging forming method for reducing the curvature of the steel when the precision forging machine forges the slender steel.
[0028] A 16MN horizontal precision forging machine is adopted, the programming software for automatic control is BarForge, and the model of the round hammer head is R120 or R150. Requirements for forging round billets: the weight of the billet must be ≤8 tons, the length of the billet must be >1.5 meters, the initial diameter of the billet must be less than Φ690mm (only for bending), the length of the finished product must be ≤20 meters, and the minimum diameter of the finished product is Φ120mm.
[0029] The blank used in this example is H13 die steel, with a weight of 3.17 tons and a specification of The forged product is H13 die steel with a specification of Φ200+2 / -0*12000mm. The specific preparation process of the product is: blank→heating→forging to the finished product size with a precision forging machine.
