This paper aims to discuss the mechanical properties and structural design of metal tool forgings. As a common industrial component, metal tool forgings are widely used in various mechanical systems. In the design and manufacturing process of tool forgings, mechanical properties and structural design are crucial factors, which have a decisive impact on the quality and service life of forgings.
Mechanical properties are one of the important properties of metal tool forgings. Common mechanical properties include tensile strength, hardness, impact toughness and so on. Tensile strength is a measure of the ability of forgings to resist damage under tensile load, and is an important index to ensure the safe application of forgings. Hardness is a physical quantity that reflects the surface hardness of forgings. For tool forgings, the increase of hardness can enhance their wear resistance and service life. Impact toughness is a measure of the ability of forgings to resist cracking under impact load. For tool forgings, good impact toughness can avoid fracture caused by impact load during use.
In the structural design of metal tool forgings, factors that need to be considered include profile section, process flow, heat treatment, etc. Profile section is the basic structure form of forging, which needs to be reasonably designed according to the use requirements and process conditions. The process flow refers to the specific operation steps and methods in the manufacturing process such as forging and heat treatment, which has an important impact on the quality and performance of the forging. Heat treatment is an important means to improve the mechanical properties of forgings, through appropriate heat treatment can adjust the hardness, strength and toughness of forgings and other mechanical properties to meet the requirements of use.
The mechanical properties and structural design of a metal tool forgings are analyzed by taking a practical design case as an example. The forging is a hammer used for hammering work. In order to ensure safety and reliability, the forging needs to have good tensile strength and impact toughness, while requiring a certain hardness of the surface to enhance wear resistance. In the structural design, the solid section is used to ensure sufficient strength and stability. The process includes heating, die forging, cooling, heat treatment and other steps, in which the heat treatment uses high temperature tempering to obtain good impact toughness and hardness.
In short, the mechanical properties and structural design of metal tool forgings are analyzed and discussed in detail in this paper. Through the in-depth understanding of mechanical properties and structural design, we can better grasp the quality and performance of forgings, optimize its design and manufacturing process, thereby improving the safety and service life of tool forgings. On this basis, we can further study new manufacturing processes and technologies to improve the performance and quality of hardware tool forgings and promote its development to a higher level.
