In S1, preparing the steel bar stock includes heating the steel bar stock to 1120 ± 5 ℃.
In S4, the heat treatment of the steel ball includes quenching at a temperature of 850 ± 5 ℃.
In this example, referring to fig. 2 and 4, the hydraulic press 1 and the electro-hydraulic hammer 2 operate simultaneously, wherein the hydraulic press 1 first forges the steel bar blank 3 to form a semi-finished steel ball 4, and then the electro-hydraulic hammer 2 forges the semi-finished steel ball 4 in multiple angles and multiple directions, wherein the hydraulic press 1 forges another steel ball for the first time in the process that the electro-hydraulic hammer 2 forges the steel ball for multiple times, and after the electro-hydraulic hammer 2 forges the previous steel ball, the electro-hydraulic hammer 1 then transfers the primarily forged semi-finished steel ball 4 to the electro-hydraulic hammer 2 for continuous forging and forming, so by the semi-automatic steel ball forging method, the forging time can be reduced when a large batch of steel balls are forged, and the production efficiency can be improved.
