| titleOfInvention | A kind of precision forging machine forging rounded square steel forming method |
| abstract | The invention relates to a method for forming rounded square steel forging by a precision forging machine, and belongs to the technical field of steel forging. In order to solve the problem that the precision forging machine cannot forge the rounded square steel billet, the present invention provides a method for forging the rounded square steel by the precision forging machine. The ~3 passes are dominated by circular deformation, and the fourth pass is transformed from a round billet to a finished rounded square steel billet. By optimizing the process parameters of the forging procedure of the precision forging machine, the invention can forge the finished product of the rounded square steel billet with high quality, high dimensional accuracy, dense and uniform structure and good surface quality, and use it for hot processing such as forging and rolling, which can avoid The product has folding defects, which improves the product qualification rate. The invention solves the problem that the square hammer head of the precision forging machine cannot produce the rounded square steel billet, and uses the round hammer head to forge the rounded square steel billet, which not only meets the product requirements, but also saves the operation time of replacing the hammer head and improves the production efficiency of the equipment. , to facilitate flexible organization of production. |
