锻造机械大多根据锻件的材质、形状和尺寸及生产规模等因素选择。由于各种锻件的形状尺寸差別很大,其成形工艺方法和模具也各不相同,因此若规定一个模锻件所需设备的力能参数的普遍计算方法或图表方法尚有困难。现就工程上所用的经验方法比较如下: 1.按经验公式选锤经验公式 Forging machinery mostly based on the forging material, shape and size and production scale and other factors to choose from. As the shape and size of the various forgings vary greatly, and their forming process and mold are also different, so if the provisions of a die forging equipment required for the energy parameters of the common calculation method or chart method is still difficult. Now on the engineering experience used in the comparison method is as follows: 1. According to experience formula hammer experience formula
