With the continuous development and update of agricultural machinery, the application of copper forgings as an important component in agricultural machinery and equipment is more and more extensive. In order to produce copper forgings of agricultural machinery with good quality and stable performance, it is necessary to conduct in-depth research on its technological flow and technological parameters.
First of all, in the manufacturing process of copper forgings for agricultural machinery, the choice of materials is crucial. Copper alloy is one of the commonly used casting materials, which has good mechanical properties, corrosion resistance and thermal conductivity. According to the specific component requirements, we can choose suitable copper alloy materials, such as copper aluminum alloy, copper nickel alloy, etc.
Secondly, sheet metal design is one of the key steps of copper forgings for agricultural machinery. According to the shape, size and functional requirements of the parts, reasonable sheet metal design is the basis for ensuring product quality. The design process needs to consider the structural form, wall thickness, fillet radius and aperture of the part, so as to improve the forging ability and machining effect of the part.
Then, mold design is an indispensable link in copper forging of agricultural machinery. Good mold design can effectively improve the accuracy and quality of products. Mold design needs to reasonably determine the shape, size and process requirements of the parts according to the sheet metal design drawings, and consider factors such as deformation and shrinkage during the forging process to ensure the accuracy and reliability of mold production.
In the material pretreatment stage, the selected copper alloy material is cut, cleaned and heated to improve the plasticity and deformability of the material. Then, the pre-treated copper alloy blank is put into the mold, and the pressure is applied by forging machinery or hydraulic equipment to make the material undergo plastic deformation and gradually form the required part shape. In the forging process, it is necessary to strictly control the process parameters such as temperature, deformation rate and deformation amount in order to obtain the ideal product performance and dimensional accuracy.
After forging is completed, it is also necessary to heat treat the copper forgings of agricultural machinery. In the process of heat treatment, the microstructure of copper alloy is adjusted by annealing, normalizing, quenching and aging, and its mechanical and physical properties are improved. At the same time, machining and surface treatment are also to further improve the accuracy and surface quality of parts. Machining includes operations such as milling, turning and drilling, while surface treatment involves methods such as spraying, coating and polishing to enhance the corrosion resistance and aesthetics of the product.
For the research of process parameters of copper forgings of agricultural machinery, on the one hand, experimental research is needed to explore the influence of different forging temperature, forging speed and forging pressure on the deformation behavior and properties of copper alloy materials. On the other hand, the numerical simulation method can also be used to simulate and analyze key parameters such as mechanical deformation, heat conduction and stress distribution in the forging process, and provide theoretical guidance for the optimization of process parameters.
To sum up, the research on the technological flow and technological parameters of copper forgings for agricultural machinery is of great significance for producing high quality products. Through reasonable selection of materials, design of sheet metal and mold, and optimization of process parameters, processing efficiency and product quality of agricultural copper forgings can be improved to meet market demand and promote the development of agricultural machinery industry.
