Analyze the different types of forging accessories

The structure of forging accessories is closely related to the choice of die forging process. The same forging can use a variety of process schemes, on the contrary, in the process scheme selection can also put forward reasonable requirements for the structure design of the forging.

First, hot die forging press die forging parts classification:

The design principle of the die forging on the hot die forging press is the same as that of the die forging on the hammer, but because the hot die forging press has a top device, the bad material can be placed vertically, and the forging parts are mostly forged without jaws, so the stability of the blank placement should be paid attention to. Forgings can be classified according to shape and forming characteristics: round cake class, long shaft class, bending shaft class.

Two, the classification of the hammer forging:

Disk class: simple shape, more complex shape, complex shape axis class: straight axis class, curved class, tooth extraction class, fork class.

Third, screw press die forging classification:

Because the screw press can be equipped with a top piece device, and can use a combination of multi-direction parting die die, forging accessories can be classified according to the shape characteristics, forming characteristics and the form of the mold used: top forging, extrusion, disk; Long-axis class; Forgings produced by combination die forging; Precision forging.

Four, the classification of tire film forgings:

Fetal film forging is a kind of technology that uses special tools (fetal film) to produce forgings on free forging equipment. The fetal membrane can be roughly divided into three categories: preforming, molding and dressing.

The dimensional accuracy and surface quality of the tire film forging mainly depend on the experience of the operator and the rationality of the selection of tooling, which is usually worse than the die forging, but compared with the free forging, the shape can be more complex and the margin can be greatly reduced. The structural elements and metal deformation mode of fetal film forgings are close to the ordinary die forging process. Circular shaft class: step class, flange class; Disc type: flange, gear, cup barrel; Ring type: ring, sleeve; Rod category: straight rod, bend rod, branch rod, fork rod.

Five, flat forging machine die forging classification:

The structural characteristics of the die forging on the flat forging machine are quite different from those on the hammer. As determined by the equipment and tooling, the flat forging process is suitable for rotating body length bar forgings with thick head and forgings with through holes or blind holes, and can forge two forging parts with dents in different directions. Classification of flat forgings: rod forgings of the lead part (no hole), rod forgings of the lead part (no hole), through hole forgings of the rod-free part, through hole forgings of the rod-free part (no hole), pipe thickness, joint die forgings.
