Agricultural machinery aluminum forging refers to the aluminum alloy as the raw material, through the forging process made of parts. Aluminum forgings have the characteristics of light weight, high strength and corrosion resistance, and are widely used in the field of agricultural machinery. The following will introduce the process flow and technology of agricultural machinery aluminum forging.
- Raw material preparation: First of all, we need to choose the appropriate aluminum alloy material as the raw material. Aluminum alloy has good malleability and mechanical properties, commonly used aluminum copper alloy, aluminum manganese alloy and aluminum magnesium alloy.
- Mold design and manufacturing: Mold design according to product shape and size requirements. The mold is generally divided into two parts: the upper mold and the lower mold, and the upper mold and the lower mold are connected through a flange or a pin. The mold should have sufficient strength and stiffness to withstand the pressure and impact force during forging.
- Heating treatment: The selected aluminum alloy material is heated to achieve the appropriate forging temperature. The heating temperature and time should be well controlled to ensure the uniform heating of the material and the refinement of the grain.
- Cutting and assembly: the preheated aluminum alloy material is cut to the appropriate length, and then assembled according to the requirements of the product. Assembly includes the assembly of multiple parts to ensure the accuracy and stability of their interconnection.
- Pre-forging and billet processing: Pre-forging is carried out on the preheated aluminum alloy material to make its deformation moderate. Then the pre-forging blanks are processed, including rough rolling, fine rolling, drawing and other processes, in order to obtain the blanks that meet the product requirements.
- Forging: the billet is put into the mold, and the pressure is applied by the press, so that the aluminum alloy material is fully filled with the mold cavity, and plastic deformation occurs under the action of pressure. The microstructure and mechanical properties of aluminum forgings can be improved by forging.
- Temperature control and cooling: in the forging process, the temperature needs to be strictly controlled to ensure the forming and performance of aluminum forgings. After forging is completed, the aluminum forgings need to be cooled to quickly cool and cure.
- Dressing and finishing: the preliminary forming of aluminum forgings will be trimmed and surface defects removed, so that it can achieve higher accuracy requirements. Finishing is then carried out, such as milling, turning, etc., to obtain the final product size and shape.
- Surface treatment and testing: Surface treatment according to the requirements of the product, such as spraying, anodizing, etc., to improve the corrosion resistance of the product. At the same time, quality testing, including size, appearance, mechanical properties and other aspects of the test, to ensure that the product meets the standards and requirements.
- Packaging and delivery: The finished product is packaged to prevent damage during transportation and storage. Then the final quality acceptance, after passing the formal factory, into the market sales or application field.
The process flow and process of agricultural machinery aluminum forging need to go through a number of links of fine operation and strict control, each link is crucial, affecting the quality and performance of the final product. In practice, manufacturers also need to combine the specific product needs and the development of process technology to continuously improve and optimize the process flow to meet the needs of the agricultural machinery aluminum forgings market.
