In the field of construction machinery, magnesium forgings are widely used in various mechanical parts and play an important role. Die is the key tool to realize the production of magnesium forgings in construction machinery, and its design and manufacturing process have an important impact on product quality and production efficiency.
First of all, mold design must be based on product design. According to the drawings and requirements of magnesium forgings of construction machinery, product design analysis is carried out, and key parameters such as the geometry, size and structure of the workpiece are determined. In the design process, the complex shape and processing requirements of the workpiece need to be taken into account to ensure the accuracy and stability of the mold.
Secondly, mold structure design is a key link. The design of mold structure includes the design of mold shape, parting way, parting surface, guiding device, etc. According to the characteristics of magnesium forgings of construction machinery, the proper parting method and parting surface should be selected to meet the product requirements and improve the production efficiency of the die. At the same time, the design of the guide device also needs to consider the mechanical deformation and stress during the processing of the workpiece to ensure the stability and reliability of the mold.
In the design of mold parts, it is necessary to design according to the requirements of mold structure design. Mold parts include mold base, upper and lower template, movable core, sliding block, guide post guide sleeve, etc. The design of these parts should pay attention to manufacturability and assembly, and reasonably determine the size and fit relationship to ensure the quality and service life of the mold.
Choosing the right mold material is also a crucial step. The commonly used materials for magnesium forging die of construction machinery are high quality alloy steel, high-speed steel, tool steel and so on. These materials should have high hardness, strength and wear resistance to meet the needs of long-term work of the mold. At the same time, the characteristics of magnesium alloy should also be considered, and its corrosion resistance and oxidation resistance should be paid attention to when selecting materials.
Process planning is an important part of mold design and manufacturing process. According to the design of mold parts and material selection, develop detailed processing technology. This includes parts CNC processing, heat treatment, surface treatment and other links. In the processing process, we should pay attention to the setting of process parameters, reasonable arrangement of processing sequence, to ensure product quality and production efficiency.
Manufacturing and assembly is the last step in mold design and manufacturing. According to mold design and process planning, mold processing and manufacturing. First of all, the parts are processed, then the heat treatment, surface treatment and other processes are carried out, and the assembly is carried out. In the assembly process, attention should be paid to the accuracy and matching size between the various parts to ensure the normal operation of the mold.
Finally, after the completion of mold manufacturing, it is necessary to debug and test. By verifying whether the performance and accuracy of the mold meet the requirements, the possible problems are modified and improved. Only after rigorous testing and debugging, the mold can be officially put into use.
To sum up, the mold design and manufacturing process of construction machinery magnesium forgings is crucial to product quality and production efficiency. Through scientific and reasonable mold design and manufacturing process, the production efficiency of magnesium forgings of construction machinery can be improved, the quality and stability of products can be ensured, and the development of construction machinery industry can be promoted.
