Abstract:

The die holder for large-size hot die forging press has some characteristics, such as high cost, long service life and complex machinability. It is of significance to choose suitable guiding form and ejecting form for the die holder, since the die forging requires high precision. The finite element analysis was run on different die holders by ANSYS Workbench.The result shows that the max stress of die holder with petal shaped ejector rod is near to that with rectangle ejector rod. The stress around the hole for rectangle ejector rod is 264MPa meanwhile that for petal shaped rod is 251 MPa, which shows that the latter is in better condition. The maxstress of die holder is 6146MPa when the corner radius of hole for ejector rod is 8 mm. It decreased to 5415MPa with a corner radius of 12mm, which indicates that the increasing corner radius makes maxstress declining. Furthermore, the rigidity of die holder with X-shaped is better than that with rear guide pin.
