Aluminum alloy drop-forged parts
Aluminum alloy drop-forged parts are objects forged with dies, using dies to forge aluminum alloy forgings that require high precision and are more complex.
Characteristics of aluminum alloy drop-forged parts
The characteristics of aluminum alloy die forging parts should be a little better for free forging, free forging basically will not use the mold, only forging shafts and rings such as simple objects, on the contrary, die forging can be forged a lot of structural products, and you can control the size of the product to reduce the amount of machining.
Aluminum alloy die forging parting surface
Dividing die surface that is the upper die and lower die forging die in aluminum alloy forgings on the interface, the development of aluminum alloy die forgings must be determined when the drawing file of die surface, and consider the following issues:
1, to ensure that the aluminum alloy forgings can be freely removed from the die slot along the direction of hammering.
2, the location of the parting die should try to make the depth of the die slot is small and wide, because wide and shallow die slot is upsetting way filled, narrow and deep die slot is pressed into the way filled, the latter metal filled to be a little more difficult, the amount of die slot wear and tear to be relatively large.
3, the mold surface should try to make the upper and lower parts symmetrical. The shape of the upper and lower molds should be the same, avoiding to make the parting surface selection on the end surface, in order to facilitate the timely detection of misalignment.
4, in order to simplify the mold manufacturing, die surface should try to make plane, not curved surface, but the second type of aluminum alloy forgings sometimes must choose curved surface die.
5, the more complex parts of aluminum alloy forgings try to arrange in the upper die, because the upper die metal is easy to fill the die slot. The above items should be considered comprehensively, in order to achieve the correct and reasonable selection of the location of the die parting surface.
