Abstract

According to the structure and operating requirements of hammer head used in hammer crusher

and the characteristics of high manganese steel

the mold design by Squeeze casting is performed.Specialized former for squeeze casting is used here

and its maximal extrusion force is 12 500 kN.The design scheme is indirect forming

and spring association is used for locking the die

while drip molding is pushed out indirectly by the subjacent fluid cylinder.It is proved in productive practice that:It is feasible to produce hammer by using this set of mold.
