In the industrial field, metal tool forgings have a wide range of applications, such as automotive, aviation, energy and so on. In order to meet the needs of different applications, it is crucial to select the right manufacturing materials and optimize the performance. This paper will introduce the method of material selection and performance optimization of metal tool forgings.
First, the selection of manufacturing materials
The raw materials suitable for manufacturing metal tool forgings include carbon steel, stainless steel, aluminum alloy, etc. These materials have different characteristics and application scenarios, which are described below.
Carbon steel
Carbon steel is an iron alloy containing carbon, which has high strength, hardness and wear resistance. In the manufacturing of hardware tool forgings, carbon steel is suitable for manufacturing tools with higher requirements and larger forces, such as hammers, pliers, screwdrivers, etc.
Stainless steel
Stainless steel is an alloy steel with high corrosion resistance and durability. In the manufacturing of metal tool forgings, stainless steel is suitable for manufacturing tools with high requirements, small forces and easy corrosion, such as screwdrivers, wrenches and so on.
Aluminium alloy
Aluminum alloy is a lightweight, highly processable and corrosion-resistant metal material. In the manufacturing of metal tool forgings, aluminum alloy is suitable for manufacturing tools with lower requirements and smaller forces, such as hammers, chisels, etc.
Second, performance optimization
In order to improve the performance and quality of metal tool forgings, it is usually necessary to optimize by heat treatment, mechanical processing, chemical treatment and other ways. These optimization methods and their effects are described below.
Heat treatment
Heat treatment is the method of heating and cooling to change the internal structure of a material, thereby improving its mechanical properties. In the manufacturing of metal tool forgings, heat treatment can improve the hardness, toughness and wear resistance of materials. For example, the quenching treatment of carbon steel can improve its hardness and wear resistance, while the solution treatment of stainless steel can improve its corrosion resistance and mechanical strength.
machining
Machining is to change the shape and size of materials by cutting, grinding, etc. In the manufacturing of metal tool forgings, machining can improve the accuracy and surface quality of materials. For example, the dimensional accuracy and surface quality of the wrench can be improved through turning processing, thus improving its performance.
Chemical treatment
Chemical treatment is to change the surface state of the material through pickling, passivation, coating and other ways to improve its corrosion resistance and wear resistance. In the manufacturing of metal tool forgings, chemical treatment can improve the rust resistance and wear resistance of materials. For example, anodizing aluminum alloys can improve their corrosion resistance and wear resistance, and passivation of stainless steel can enhance their corrosion resistance.
- Case analysis
Select a practical application example to show how to select manufacturing materials and optimize performance according to specific needs. For example, to make a hammer, it needs to withstand a large impact force and knocking force, while requiring good wear resistance and rust prevention.
Manufacturing material selection
Considering that the hammer needs to withstand a large impact force and knocking force, carbon steel can be chosen as a manufacturing material. Carbon steel has high strength, hardness and wear resistance, which can meet the requirements of mechanical properties of hammers. In addition, in order to prevent the hammer from rusting during use, anti-rust treatment can be applied to the surface, such as coating or painting.
Performance optimization
First of all, the carbon steel can be quenched by heat treatment to improve its hardness and wear resistance. In addition, in order to further enhance the corrosion resistance of the hammer, passivation treatment can be carried out on the surface. In terms of machining, the dimensional accuracy and surface quality of the hammer can be guaranteed through accurate turning and grinding. Finally, chemical treatments such as coating or spray paint can enhance the hammer’s rust resistance.
In summary, through reasonable selection of manufacturing materials and performance optimization, hammers that meet actual needs can be manufactured to improve their performance and service life.
