Aluminum Free Forgings
Aluminum free forging products:
Free forging is a kind of forging method, in which the blank is heated to the forging temperature, under the action of free forging equipment (forging hammer or press) and simple tools (hammer or anvil, etc.), general tools and movable simple combination dies are used to control metal deformation by manual operation to obtain the desired shape, size and quality. The shape and groove of the membranes used are relatively simple, convenient to manufacture and low in cost. The main forging processes used are upsetting, drawing, punching, reaming and bending.
Free forging of aluminium and aluminium alloys has the following advantages:
1) Free forging can improve the structure and properties of aluminium alloy. The quality and mechanical properties of aluminium alloy free forgings are higher than those of castings, and their strength is 50%-70% higher than that of castings. Therefore, they can withstand large impact loads. The plasticity, toughness and other mechanical properties of aluminium alloy free forgings are higher than those of castings. The weight of the parts themselves is more important for aircraft, aerospace equipment, vehicles and vehicles.
2) Free forging can save raw materials.
3) Free forging is suitable for single piece and small batch production, and the variety change is more flexible.
4) Free forging is a common forging method. Because free forging does not use special dies, forging tools are universal and the cost of production is low. It is suitable for the production of single piece, small batch forgings, urgently needed super large forgings, and trial production of forgings for new products under special conditions.
5) Streamline distribution of straight or bending axles and finished annular parts is generally more reasonable than that of die forgings because there is no transverse flow of metal. It is especially suitable for shaft, disk or ring parts with simple shape, small cross-section change and flat straight or curved spindle.
Aluminum free forging raw materials: 1) Ingot blanks should be made from small grains of ingot blanks. In addition, homogenization annealing should be carried out before use to improve product structure and plasticity. 2) Generally speaking, extruded blanks are often used in forging free forgings of medium, small and low plastic aluminium alloys. However, upsetting and elongation of extruded wool should be carried out to eliminate the influence of anisotropy of extruded bar
Classification of aluminum free forgings:
Aluminum free forging is a universal process, which can forge forgings of various shapes. According to the characteristics of forging process,aluminium free forgings can be divided into four categories:
Aluminum forged block, aluminum forged ring and aluminum forged cylinder, shaft and rod forgings, bending forgings, etc.
1) Aluminum forged round disc. This category includes various discs.
2) Aluminum forged ring cylinders. These include various rings and cylinders.
3) Aluminum forged shaft rod . This kind includes all kinds of round, rectangular, square, I-shaped cross-section bar, etc.
4) Aluminum bending forgings. This category includes forgings of various bending axes, such as bending rods.
