Abstract

The invention aims at providing a rear axle aluminum alloy control arm forming device and a forming method. One side, where a projection is produced, of a rear axle aluminum alloy control arm can be limited from being excessively deformed, and a manufacturing process is simplified. The rear axle aluminum alloy control arm forming device comprises a base, a top plate, a supporting mechanism, a first pressing die, a second pressing die and a third pressing die; the supporting mechanism is arranged at the two sides of the base, the top plate is arranged above the supporting mechanism, and the top plate stretch across the supporting mechanism and is supported by the supporting mechanism; the first pressing die and the second pressing die are arranged at the two sides of the base along a first direction, a forming end is fixedly arranged between the first pressing die and the second pressing die, the first pressing die and the second pressing die can be close to each other in the first direction, so that extrusion on the forming end is realized, and the projection is produced at one side, toward the top plate, of the forming end; and the third pressing die is fixedly arranged at one side, toward the base, of the middle part of the top plate, and the third pressing die can be contacted with the projection and apply a pressure to the projection.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, and more specifically, to a forming device and a forming method for an aluminum alloy control arm of a rear axle. Background technique [0002] In the field of automobile manufacturing, with the development of automobile lightweight technology and its application in chassis parts, the trend of rear axle aluminum alloy control arm parts replacing traditional steel parts is becoming more and more significant. [0003] At present, due to the high cost of aluminum alloy welding, the manufacturing process of the rear axle aluminum alloy control arm has gradually changed from steel plate stamping and welding to aluminum alloy extrusion profile cutting, bending, partial forming, edge trimming, punching and shaping. Local forming is to improve the local strength of the product and conform to the assembly size of the product. Stamping equipment is used for molding to achieve work hardening and pref...
