Round steel forging and pressing process

Abstract

The invention relates to the technical field of round steel forging and pressing, and discloses a round steel forging and pressing process which comprises the following specific steps: S1, heating; s2, upsetting operation is carried out; s3, performing drawing-out operation; s4, finishing; s5, adjusting the size and the shape; s6, heat treatment operation; by means of the scheme, the quality and performance of products can be improved, the round steel is evenly heated and fully austenitized by accurately controlling the heating temperature, time and curve, a good structure foundation is provided for the subsequent forging and pressing procedure, the heading and drawing-out technology is optimized, the problems of internal defects and uneven deformation of the round steel are solved, and the product quality and performance are improved. Heat treatment process parameters are reasonably selected and accurately controlled, the organization structure of the round steel is improved, and the strength, hardness, toughness and fatigue performance of the round steel are further improved; by means of the scheme, the production efficiency can be improved, the cost can be reduced, the improved technology is more normalized and standardized in preparation work such as equipment inspection and mold installation and debugging, and equipment faults are reduced.
