[CN 202010070400.5] Forming method for forging rounded square steel by precision forging machine


[CN 202010070400.5] A Precision Forging Machine Forging Fillet Square Steel Forming Method Title: A Precision Forging Machine Forging Fillet Square Steel Forming Method Application Number: CN 202010070400.5 Applicant: Jianlong Beiman Special Steel Co., Ltd. Application Date: 2020-1-21 Patent Type: Invention Application The present invention relates to a Precision Forging Machine Forging Fillet Square Steel Forming Method, belonging to the technical field of steel forging. In order to solve the problem that the fine forging machine cannot forge the rounded square steel blank, the present invention provides a fine forging machine forging rounded square steel forming method, the method forging forming using round hammer head, a total of 4 times, the 1st to 3 times to round deformation, the 4th pass blank by round billet deformation into the finished rounded square steel blank. The invention, by optimizing the forging process parameters of the precision forging machine forging process, forging the finished product of high quality, high dimensional accuracy, dense and uniform tissue, and good surface quality of the rounded square steel blank, which is used for forging, rolling and other hot processing, can avoid the product folding defects and improve the product pass rate. The invention solves the problem that the square hammer head of the precision forging machine cannot produce rounded square steel blanks, and uses the round hammer head to forge rounded square steel blanks, which not only meets the product requirements, but also saves the working time of replacing the hammer head, improves the production efficiency of the equipment, and facilitates flexible organization of production.
