introduction：ziyouduan Free forging open die forging Use simple tools and open molds（Anvil block）A method of forging and forming metal。Free forging time，Only part of the surface of the metal is in contact with the tool or anvil block，The rest of the surface is free deformation。Free forging uses common dies and tools，Great flexibility，Low cost，The production preparation cycle is short，Suitable for single piece、Small batch production。But the productivity of free forging is low，The labor intensity of workers is high，Poor accuracy of forging，Large processing allowance，Therefore, the proportion of free forgings in the total number of forgings varies with the production
