This paper discusses the important influence of hot forging die design and manufacture on forging quality. Firstly, the basic concept and principle of hot forging die are introduced, and then its influence on forging quality is analyzed from the aspects of die material selection, design parameters and manufacturing process, and corresponding optimization suggestions are put forward. Reasonable design and manufacture of hot forging die is of great significance for improving forging quality and reducing production cost.
Hot forging die is a key component in hot forging process, and its design and manufacturing quality directly affect the shape, dimensional accuracy, surface quality and mechanical properties of the forging. Therefore, in the process of hot forging production, we must pay attention to the design and manufacture of hot forging dies to ensure the stability and improvement of forging quality.
Influence of hot forging die design and manufacture on forging quality
Die material selection: Hot forging die need to withstand high temperature, high pressure and severe friction and other harsh conditions, so the choice of die material is very important. Suitable materials should have high heat resistance, wear resistance, fatigue resistance and good cutting performance. If the mold material is not selected properly, it may lead to early failure of the mold, which will affect the accuracy and surface quality of the forging.
Design parameters: The design parameters of hot forging die include die structure, size, radius of rounded corner, drawing slope, etc. The selection of these parameters directly affects the metal flow, filling effect and forging forming quality. Reasonable design parameters can ensure the uniform flow of metal in the die, avoid folding, cracking and other defects, and improve the mechanical properties of forgings.
Manufacturing process: The manufacturing process of hot forging die includes cutting, heat treatment, surface treatment, etc. The precision and stability of the manufacturing process have an important impact on the accuracy and life of the mold. If the manufacturing process is not proper, it may lead to problems such as the mold size is out of whack, the surface roughness is not up to standard, and then affect the shape and dimensional accuracy of the forging.
Optimization suggestion
Selection of appropriate mold materials: According to the specific requirements of the hot forging process and working conditions, the selection of mold materials with high heat resistance, wear resistance and good cutting performance, such as high-speed steel, cemented carbide, etc.
Optimization of design parameters: Through numerical simulation and experimental verification, optimize the design parameters of hot forging die, such as rounded radius, die slope, etc., to improve metal flow and improve forging forming quality.
Improve the manufacturing process level: the use of advanced cutting equipment and technology to ensure the manufacturing accuracy of the mold; Strengthen the control of heat treatment and surface treatment process, improve the hardness and wear resistance of the mold, and extend its service life.
Regular maintenance and maintenance: Establish a regular maintenance and maintenance system of molds, timely find and deal with mold wear, cracks and other problems, to ensure the stable development of hot forging production.
The design and manufacture of hot forging die is the key factor affecting the quality of forging. Through reasonable selection of die materials, optimization of design parameters and improvement of manufacturing technology, the performance and life of hot forging die can be effectively improved, and then the stability and improvement of forging quality can be ensured. In the actual production process, attention should be paid to the design and manufacturing of hot forging dies, and constantly optimize and improve to meet the increasing market demand and product quality requirements.
