Die is an important tool in forging production, and its design and material selection directly affect the quality and production efficiency of forging. This paper will discuss the die design and material selection of forging production from two aspects.
In the forging production process, the design of the mold needs to take into account a number of factors, such as the size, shape, material and so on. At the same time, the design of the mold also needs to be in line with the factory’s production line and equipment to ensure that the mold can smoothly and efficiently produce forgings. The following are some factors to consider when designing molds:
The size and shape of the forging: The design of the mold needs to determine the size and shape of the mold according to the size and shape of the forging. At the same time, it is also necessary to take into account the material flow and forming during the forging production process to ensure the size and shape accuracy of the forging.
Forging materials: Different forging materials require different die materials and designs. For example, for the forging production of high-strength steel, it is necessary to choose wear-resistant and impact-resistant die materials, while for the forging production of light metals such as aluminum alloys, it is necessary to choose die materials with good thermal conductivity and low wear resistance.
Production process and equipment: Mold design needs to consider the production process and equipment. For example, for the production of forgings using the hot die forging process, it is necessary to choose a mold material that is resistant to high temperature and wear, while for the production of forgings using the cold die forging process, it is necessary to choose a mold material with good wear resistance and high strength.
Material selection is an important part of the mold design, it is necessary to choose the mold material that meets the forging material standard, and consider the thermal expansion and contraction coefficient, hardness, tensile strength and other indicators of the material, to ensure that the mold can remain stable under repeated heat and mechanical tension. Here are some factors to consider when selecting materials:
Wear resistance of the material: The mold material needs to have a high wear resistance to extend the service life of the mold.
The strength of the material: The mold material needs to have a high strength to withstand the mechanical tension and impact force.
Thermal conductivity of the material: The mold material needs to have good thermal conductivity in order to quickly conduct the heat out and avoid overheating of the mold.
Thermal expansion and contraction coefficient of the material: the thermal expansion and contraction coefficient of the die material needs to be similar to the thermal expansion and contraction coefficient of the forging material to avoid excessive thermal stress during the heating and cooling process.
Material processing properties: Mold materials need to have good processing properties in order to facilitate manufacturing and maintenance.
In the process of forging production, die design and material selection are important factors that affect the quality and production efficiency of forging. In order to improve the quality and production efficiency of forgings, it is necessary to carry out detailed mold design and material selection according to the specific situation. In actual operation, many factors need to be considered, such as the size, shape, material, production process and equipment of the forgings, to ensure that the mold can produce the forgings smoothly and efficiently. At the same time, when selecting materials, it is necessary to consider the wear resistance, strength, thermal conductivity, thermal expansion and contraction coefficient and processing performance of the material to ensure the stability and service life of the mold. Only in this way can we better meet the market demand and create greater economic benefits and market competitiveness for enterprises.
