Abstract

The blow procedure of a die-forging hammer is analysed theoretically taking account of the elastic deformation of the cushion under the anvil block, and the new formulae for calculating the maximum blow force are deduced from a new model proposed in the paper. The results calculated by the formulae agree well with experimental data. Thus, the formulae and the results provide a basis for designing and using die-forging hammers properly.
