The aluminum forging process mainly includes the following steps:
Preparation work:
Select appropriate forging equipment: According to the size and shape of the aluminum alloy parts to be forged, select appropriate forging equipment, such as hydraulic forging machine, pneumatic hammer, etc.
Prepare raw materials: Select appropriate aluminum alloy materials to ensure that their chemical composition and physical properties meet the requirements.
Mold preparation:
Design and manufacture molds: According to the requirements of the shape and size of the parts, design and manufacture the corresponding molds. The mold is usually composed of an upper mold and a lower mold to hold and shape the aluminum alloy material.
Heat treatment:
Heating aluminum alloy materials: Heat the aluminum alloy materials to an appropriate temperature, generally the solid solution temperature range of the aluminum alloy, to improve the plasticity and forgeability of the material.
Precise temperature control: According to the type and requirements of the aluminum alloy materials, accurately control the heating temperature and keep the temperature constant.
Forging process:
Put the aluminum alloy material into the mold: Put the preheated aluminum alloy material into the mold to ensure that the material is in full contact with the mold surface.
Hammering or hydraulic forging: According to the type of forging equipment selected, the aluminum alloy material is hammered or hydraulically forged using the corresponding process means to form a predetermined shape and size.
Repeated hammering or hydraulic processing: As needed, multiple hammering or hydraulic processing can be repeated to gradually approach the target shape and size.
Cooling and annealing:
Cooling forged parts: During the forging process, the forging parts may generate a high temperature, which needs to be gradually cooled to room temperature to increase the hardness and strength of the material.
Annealing treatment: For some aluminum alloy materials, annealing treatment is required after forging to eliminate stress and improve the toughness and machinability of the material.
Surface treatment:
Trimming and cutting: Trim and cut the forged parts to remove unnecessary excess material and surface unevenness to make them meet the required shape and size. Cleaning and deoxidation treatment: Clean surface impurities and oxides by chemical cleaning or electrolytic cleaning to facilitate subsequent processing and surface treatment.
