How to improve the utilization rate of raw materials in aluminum forging

Forging is a method of applying pressure to metal raw materials with forging machinery to promote deformation and change the internal structure state. During the metal smelting and manufacturing process, due to the sparse casting state of the metal itself and the low mechanical strength, problems such as peeling and cracking are prone to occur after the casting is formed. Casting can change the internal structural characteristics of the metal before casting, make it dense and tough, and maintain the good characteristics of the product.

In the existing aluminum forging process, it is easy to ignore the oxide layer on the surface of the aluminum material during forging, and the surface film affects the thickness of the forging layer of the material during forging, and also affects the structural characteristics of the forging itself, which is prone to peeling, roughness, etc. Crystal and other problems, the product quality after forging is more higher.

Aluminum forging the preparation before forging includes selection of raw materials, calculation of materials, delivery of materials, heating, calculation of deformation force, selection of equipment, and design of molds. The lubrication method and lubricant must be selected before forging.

There are a wide range of forging materials, including various grades of steel and high-temperature alloys, as well as non-ferrous metals such as aluminum, magnesium, titanium, and copper; there are bars and profiles processed into different sizes at one time, and ingots of various specifications.

As we all know, the quality of products is closely related to the quality of raw materials, so forging operators need the necessary knowledge of materials, and must be good at selecting better materials according to process requirements.

The input of materials and materials is one of the important links to improve the utilization rate of aluminum forgings and realize the refinement of blanks. Not only is too much material wasted, but bore wear and energy consumption worsen. If there is not a little surplus of raw materials, it will increase the difficulty of process adjustment and increase the waste rate. In addition, the quality of the end face of the raw material will also affect the quality of the process and forgings.

The purpose of aluminum forging is to reduce forging deformation force and improve metal plasticity. However, heating will bring a series of problems such as oxidation, decarburization, overheating, and overburning. Correctly controlling the forging start temperature and forging end temperature has a great influence on the structure and performance of the product.

Jiahangaero said that because forging is formed by external force, correct calculation of deformation force is the basis for selecting equipment for mold inspection. Analyzing the stress and strain inside the deformed body is also indispensable for optimizing the process and controlling the microstructure and properties of forgings.The cost of raw materials in aluminum forging production accounts for 50%~70% of the production cost of forgings. Saving raw materials is the main means to reduce the production cost of forgings. Turn material cutting into material shearing or precision shearing as much as possible, develop new precision shearing technology and equipment, popularize band saw machines, and develop new high-speed circular saw blades such as high-speed steel circular saw blades or bimetallic blade circular saw blades . The main measures to improve the productivity of aluminum forging and forging materials, reduce material loss and save raw materials
