WebAug 16, 2024 · The forging force required to perform a closed-die cold forging operation can be calculated using: Where: k = multiplying factor Yf = flow stress of the material (Pa) A = projected area of the forging, including the flash (m2) The range of k values for different kinds of shapes has been provided in Table 1. Table 1. WebSTEPS FOR THE DESIGN OF FORGED PART 4.1 Parting Line Die parting line is the plane which divides the top and bottom dies in a close die forging. This depends upon the ease of die filling, forging equipment, grain flow, jib locations and trimming facility. Proper parting line avoids deep impressions that might cause die breakage.

Webforging, is one of the manufacturing processes where metal is pressed or forced under great pressure into high strength parts. Before the process, lubricant is applied to the dies in ... area ratio was introduced to reveal the effect of friction in contact area expansion [5].

WebFeb 19, 2024 · Request PDF Effect of forging ratio on tensile properties and fatigue performance of EA4T steel In this study, EA4T axle steel was hot-forged using the forging ratios of 2.0, 3.0, 4.0, and 5.0. Web• Entire forging is plastic – no elasticity • Material is perfectly plastic – strain hardening and strain rate effects later • Friction coefficient (µ) is constant – all sliding, to start • Plane … WebJan 6, 2024 · With the increase in forging reduction, the axial residual stress gradually decreased, which decreased by 8% when the forging ratio was 42.7%. The deformation through the thickness direction was influenced by the forging ratio, and the degree of nonuniform deformation affected the distribution of residual stress (Ref 25 , 26 ). houghton wales
