The temperature to start the forging for soft, low carbon steels is 1,250 to 1,300°C, the temperature to finish forging is 800 to 840°C. While, in the second stage the workpiece will obtain its final shape after trimming. Depending on the forging temperature and post treatment, Alloy 7 18 can be grouped into three different types; i.e, standard, high strength and direct age versions[l]. B.-A. In this eBook, we will explain you all aspects of metal forging. Forged parts are used in high performance, high strength and high reliability applications where tension, stress, load and the human safety are critical considerations. Calculation of length of the raw material required to do themodel. The thermal load in particular is able to cause constant changes in the hardness of the surface layer, which in turn has a decisive influence on the numerical estimation of wear. 0000000631 00000 n The condition of a forging as it leaves the open die without any subsequent operations.

Edition November 2015 Page 7 Coining is essentially a cold forging operation except for the fact that the flow of the metal occurs only at the top layers and not the entire volume. The stress calculation can be done by equipment influences the forging process because it affects deformation rate, forging temperature, and rate of production. The basis of many formulas used for such tonnage calculations are uniform and even shapes, with easily calculated surfaces areas, length or volumes. cylinders, slabs etc. 2. forging may be used especially for complex geometry forging of a superalloy disk with a uniform microstructure and properties. 1: volume of work piece before forging = volume of work piece after forging. Email. 0000060769 00000 n Unit 3: Forging Definition: Forging is a metal working process in which useful shape is obtained in solid state by hammering or pressing metal. Forging is often classified … C50 steel, ultimate tensile strength can be taken as 800 MPa. The condition of a forging as it leaves the open die without any subsequent operations. Forging is a metal working process in which useful shape is obtained in solid state by hammering or pressing metal.

The design of a forging process involves the calculation or the prediction of (1) Forging volume and weight (2) Number of blocker shapes to be used, if any (3) Flash geometry, flash width, and flash thickness (4) Flash weight and scale losses (5) Total forging weight, including scale and flash losses. 2.4.4 Total Forging Load for Upsetting Stage Thus, using the symbol, one has: The total forging load, Pt at the upsetting stage is ∆v4 = π ∆s (Rs- Hs tanαs)2 (10) the sum of the loads necessary to extrude the shaft, Ps, and ∆v23= π Rn2 ∆h (11) to upset zone 1, P1, and to upset zone 2, P2. for a pressure vessel of the EPR reactors AP1000 the required press power is 150 MN and an ingot weight 350 t, at least. In this paper the concentration is given to the calculation of rolling load and the forces acting on the gears of steel rolling machine. In hot working, appropriate flow stress at that temperature is used. 52 Nageswara Rao Posinasetti February 6, 2012 Coining Rule-based expert system and training set generation One of the needs of NN supervised learning is the availability of a training set, made up of known examples, large enough to allow for knowledge acquisition and storage in the NN structure [2]. The above equation is applied to find the maximum force during the operation, since this is the load that will determine the required capacity of the press used in the forging operation. The homologous temperature T H is used to distinguish it from the cold forming process.. T H = 0.6 x T S (T S: Melting temperature of the material – all figures in K). (2011) considered deflection of workpiece, process in which deformation occurs under non-steady die, punch and press to calculate the load in multi-stage state and non-uniform metal flow amidst interface cold forging to make quality product.
