Overview of hot die forging technology

Hot die forging technology refers to a process method of forming metal billet with die under high temperature. Through hot die forging technology, the metal billet can be heated to the austenitic state, so that it has good plasticity and forming properties, so that various complex shapes can be formed in the mold. Hot die forging technology has the advantages of high efficiency, high precision and high reliability, so it is widely used in mass production.

2. Process flow of hot die forging technology

The process flow of hot die forging technology includes manufacturing material preparation, heating temperature control, cooling shrinkage control and other key links.

Preparation of manufacturing materials: Select suitable hot forging materials, such as steel, aluminum alloy, etc., and ensure that the size and quality of the metal blank meet the requirements.

Heating temperature control: the metal billet is heated to the austenitic state, and the general heating temperature is between 800-1200 ° C, while ensuring that the billet is evenly heated.

Cooling shrinkage control: The metal billet after forming in the mold needs to be cooled quickly to control its shrinkage and hardness and ensure product quality.

Equipment and technology of hot die forging technology

Hot die forging technology requires the use of a variety of professional equipment and tools, such as hot die forging machine, press, shearing machine, etc. Among them, the hot die forging machine is the most important equipment, which is composed of pre-forging die, final forging die and heating device, which can be selected and adjusted according to different product needs. The press is used to compress the metal billet in a hot state to achieve its deformation and forming purposes. The shearing machine is used to remove the formed metal blank from the mold and cut it for subsequent treatment and processing.
