As an important component in manufacturing industry, precision forgings are widely used in aerospace, energy equipment, medical equipment and other fields. However, for most people, the production process of precision forgings is still full of mystery. This article will take you into the production line of precision forgings, revealing the complete production process from raw materials to finished products.
Raw material preparation
The production of precision forgings cannot be separated from high-quality raw materials. Usually, different metal materials are selected according to product requirements, such as steel, aluminum, copper, etc. After entering the factory, raw materials need to undergo strict inspection to ensure that their chemical composition and physical properties meet the production requirements.
Smelting and casting
After the inspection of qualified raw materials, will be sent to the melting furnace for melting. In this process, the raw material is heated to high temperatures, causing it to melt into a liquid state. In the melting process, parameters such as temperature and time need to be strictly controlled to ensure the purity and quality of the metal liquid.
After smelting is complete, the liquid metal is poured into a mold for casting. The shape of the die determines the initial shape of the forging. The casting process needs to control the flow speed and temperature of the metal liquid to prevent defects.
Forging and forming
The billet obtained from the casting will be sent to the forging equipment for forging. Forging is a process in which the blank is plastically deformed by applying pressure to achieve the desired shape and performance. In the forging process, the blank is heated and deformed several times, and gradually approaches the shape of the final product.
After forging is completed, the forgings need to be heat treated to improve their internal organization and properties. Heat treatment includes quenching, tempering, normalizing and other processes, which can improve the hardness, strength, toughness and so on.
Machining and surface treatment
Forgings after forging and heat treatment usually need to be machined to meet more precise dimensions and surface quality requirements. Machining includes turning, milling, grinding and other processes, which can remove the oxide skin and burrs on the surface of the forging and improve the surface finish.
Finally, according to product requirements, forgings may require surface treatment, such as galvanizing, spraying, etc., to improve their corrosion resistance and aesthetics.
Inspection and packing
At all stages of the production process, the forgings need to be strictly inspected. The inspection items include dimensional accuracy, chemical composition, mechanical properties, surface quality, etc. Only forgings that pass the inspection can be regarded as qualified products.
Qualified products will be cleaned, dried, etc., and then packaged. Anti-rust, anti-shock and other measures should be taken during the packaging process to ensure that the product is not damaged during transportation and storage.
From raw materials to finished products, the production process of precision forgings has experienced a number of carefully built links. Each link needs to strictly control the parameters to ensure product quality. It is this meticulous spirit that creates the high quality and wide application of precision forgings. I hope that through the introduction of this article, you can have a deeper understanding of the production process of precision forgings.
