NUMERICAL SIMULATION OF COMBINED FORWARD-BACKWARD EXTRUSION TFHE BODY OF AUTOMATIC VALVE

The paper analyses the process of simultaneous forward-backward extrusion of the body of automatic valve for central low pressure heating installations. In metal forming industries, many products have to be formed in large numbers and with highly accurate dimensions. to save energy and material it is necessary to understand the behaviour of material and to know the intermediate shapes of the formed parts and the mutual effects between tool and formed part during the forming process. These are normally based on numerical methods which take into account all physical conditions of the deformed material during the process. For this purpose, the Finite Element Method (FEM) has been developed in the past in different ways. the paper highlights the finite element simulation as a very useful technique in studying, where there is a generally close correlation in the load results obtained with FEM and those obtaine experimentally.
