Abstract：
|
|
Thick metal plate blanking process on free forging hammer and the forging die construction are introduced together with the method by solving the matter of the intensive blade wear when small blade clearance is applied.A lubricant formulation to reduce wear and prolong die service life is developed.Die for thick plate punching on free forging hammer is designed,which can expand the machining application of free forging equipment and solve the manufacturing problems in case that there is no available heavy-duty press.
