1, according to the type of automobile forgings to classify:
a. Round cake: such as gear and wheel hub
b.Rod type: such as connecting rod, steering hammer arm
c.Crank class: such as crankshaft, camshaft
d. Axis class: such as the front axis
e. Fork class: such as knuckle, flange fork
Classification by process use:
Our factory is mainly forging press production of automobile forgings, so according to the characteristics of our production process is mainly divided into:
a.Roller forging die: general rod parts have this die, such as connecting rod
The upsetting die: This kind of die is mostly round cake parts
b. Pre-forging die: basically all forgings have this step, so the die always exists;
c.Final forging die: each part must have this die, this is the final forming die;
d. Cutting and punching die: in addition to closed forging, all forgings should be edging, individual forgings need punching;
e. Correction mold: This mold is basically every forging will be used, because there is deformation after heat treatment of forging
