In the industrial field, metal tool forgings have a wide range of applications, such as machinery manufacturing, construction, automobiles, ships and other fields. Therefore, improving the mechanical properties of metal tool forgings is of great significance for improving product quality, reducing cost and enhancing safety. This paper will introduce the basic concept, classification and application of metal tool forgings, and explain the optimization method of mechanical properties and application examples.
First, the basic concept and classification of metal tools forgings
Forgings refer to metal tools made through the forging process, including a variety of hand and power tools, such as hammers, pliers, screwdrivers, drills, etc. These forgings can be divided into the following categories:
Classification by use: can be divided into general tools and special tools. General tools include hammers, pliers, screwdrivers and other commonly used hand tools, special tools include drill, milling cutter, cutting machine and other precision power tools.
Classification by material: can be divided into steel forgings, aluminum alloy forgings, copper alloy forgings and so on.
According to the manufacturing process classification: can be divided into free forging, die forging and precision forging.
Second, the application of metal tools forgings
Metal tool forgings have a wide range of applications in various fields, such as:
Industrial field: In machinery manufacturing, automobile manufacturing, shipbuilding and other industries, hardware tools forgings are essential processing tools and maintenance tools.
Construction field: In the construction site, hand and power tools are essential construction tools.
Transportation field: In the process of manufacturing and maintenance of transportation vehicles such as automobiles, ships, aircraft, hardware tools forging is also an indispensable tool.
Third, the mechanical properties of metal tools forgings
The mechanical properties of metal tool forgings are one of the important indicators to measure the quality of forgings, mainly including tensile strength, hardness, toughness and so on. Tensile strength refers to the maximum bearing capacity of a material under tensile load. Hardness refers to the ability of the surface of the material to resist deformation and scratches; Toughness refers to the ability of a material to absorb energy when subjected to impact loads. These mechanical properties have an important impact on the service life, safety and wear resistance of forgings.
Fourth, mechanical properties optimization method of metal tools forgings
In order to improve the mechanical properties of metal tool forgings, the following optimization methods can be used:
Heat treatment: By controlling the heating and cooling speed, the internal structure of the metal is adjusted to improve its mechanical properties. For example, tempering steel forgings at high temperature can reduce their hardness and improve their toughness, thereby improving their service life.
Surface treatment: Through surface coating, hardening treatment and other methods to improve the hardness and wear resistance of the forging surface to extend its service life. For example, anodizing on the surface of aluminum alloy forgings can form a dense oxide film on its surface to improve its hardness and wear resistance.
Process optimization: improve the quality and accuracy of forgings by improving the processing process to reduce errors and deformation. For example, the use of die forging process to produce aluminum alloy forgings can make its precision higher and mechanical properties more stable.
Application examples of metal tools forgings
In the industrial field, metal tool forgings are widely used in machinery manufacturing, automobile manufacturing, shipbuilding and other industries. For example, in machinery manufacturing, free forgings and die forgings are used to produce a variety of gear, shaft parts and other key components; In automobile manufacturing, metal tool forgings are used to produce all kinds of piston, crankshaft, valve and other key components; In shipbuilding, metal tool forgings are used to produce various key components such as propellers and rudders. These forgings need to have high strength, hardness and toughness to ensure their safety and reliability.
In the field of construction, hand and power tools are essential construction tools. For example, in construction sites, hand tools such as hammers, pliers, screwdrivers are used to carry out various construction operations; At the same time, power tools such as drills, milling cutters, and cutting machines are used to carry out a variety of fine machining operations. These tools all need to have high hardness and wear resistance to ensure their service life and safety.
In the field of transportation, the manufacture and maintenance of vehicles such as automobiles, ships, and aircraft require the use of hardware forgings. For example, in automotive manufacturing, a variety of hand and power tools are used to install, adjust and repair parts; In Marine and aircraft manufacturing, a variety of hand and power tools are used to carry out various equipment installation and maintenance operations. These tools all need to have high hardness and wear resistance to ensure their safety and reliability.
In short, metal tool forgings have a wide range of applications in various fields, and the optimization of its mechanical properties is of great significance for improving product quality, reducing costs and enhancing safety. Through the research and application of optimization methods in heat treatment and processing technology, the mechanical properties and service life of metal tool forgings can be further improved, and more reliable support for production and maintenance work in various industries can be provided.
