As an important part of power system, the quality of power fixture forgings directly affects the safe and stable operation of power system. With the continuous development of the power industry, the demand for power fittings forgings is also increasing, and the requirements for product quality are more stringent. Therefore, it is of great significance to study the production process, optimize the production technology and improve the product quality and production efficiency.
At present, domestic and foreign scholars have done some research on the production process of electric power fittings forgings. In the production process, it mainly includes heat treatment, forging and processing. The main purpose of heat treatment is to improve the mechanical properties of materials and increase the strength and toughness of products. The forging process mainly involves the deformation and flow of the material, and it is necessary to control the parameters of forging temperature, speed and deformation degree. The processing link mainly includes cutting, grinding and other processes, and the processing accuracy and surface quality need to be controlled.
However, in the actual production process, due to the influence of various factors, there are often some problems, such as unstable product quality and low production efficiency. These problems are mainly caused by unreasonable production process, aging equipment, non-standard personnel operation and other reasons. Therefore, it is necessary to model and optimize the production process of power metal forgings to improve product quality and production efficiency.
When establishing the production process model of electric power fixture forging, it is necessary to consider the interrelationship and influence of each production link. The heat treatment link mainly affects the mechanical properties of the material, the forging link mainly affects the deformation and flow of the material, and the processing link mainly affects the precision and surface quality of the product. Therefore, the production process can be divided into these several links, and the model is established separately.
Heat treatment model
The heat treatment model mainly considers the effects of temperature, time and cooling rate on the mechanical properties of materials. The finite element method can be used to simulate the mechanical properties of materials at different temperatures, and then the material properties parameters at any temperature can be obtained by interpolation method. It is also necessary to consider the performance and characteristics of the heat treatment equipment in the model, as well as the difference in the response of different materials to heat treatment.
Forging model
The forging model mainly considers the characteristics of material deformation and flow, as well as the influence of forging temperature, speed and deformation degree on product quality. The rigid plastic finite element method can be used to simulate the flow model of the material under different forging conditions, and then the shape and size of the product can be obtained by numerical calculation. It is also necessary to take into account the performance and characteristics of forging equipment, as well as the difference in the response of different materials to forging.
Machining model
The machining model mainly considers the effect of cutting, grinding and other processes on product accuracy and surface quality. Numerical control programming software can be used to simulate, establish the mathematical model of cutting, grinding and other processes, and then obtain the precision and surface quality of the product through numerical calculation. It is also necessary to take into account the performance and characteristics of the processing equipment, as well as the difference in the response of different materials to processing.
Through the modeling of each link, the model of the whole production process can be obtained. Then through data fitting and parameter optimization, the model is verified and modified to make it more in line with the actual production situation.
After establishing the production process model of electric power tool forgings, the model can be optimized by changing the production process, equipment, personnel configuration and other parameters to improve product quality and production efficiency. Specific measures can be taken as follows:
Optimized heat treatment process
By adjusting the parameters of heat treatment temperature, time and cooling rate, better mechanical properties of materials can be obtained. New heat treatment equipment and processes can be used, such as vacuum heat treatment, induction heat treatment, etc., to improve product quality and production efficiency.
Optimize forging process
By adjusting parameters such as forging temperature, speed and deformation degree, better product shape and size can be obtained. New forging equipment and processes can be used, such as high-speed forging, precision forging, etc., to improve product quality and production efficiency.
Optimized processing technology
By adjusting the process parameters such as cutting and grinding, better product accuracy and surface quality can be obtained. New processing equipment and processes can be used, such as numerical control processing, ultrasonic processing, etc., to improve product quality and production efficiency.
Optimize staffing and equipment maintenance
The influence of human factors on product quality can be reduced through professional training of personnel and improvement of operating standards. At the same time, strengthening the maintenance and maintenance of the equipment can extend the service life of the equipment and improve production efficiency.
In this paper, the production process model of electric power fixture forgings is established and optimized. By changing the production process, equipment, personnel configuration and other parameters, the product quality and production efficiency can be improved. These optimization measures are of great significance to improve the quality and competitiveness of power fittings forgings. In the actual production, it is necessary to choose the appropriate optimization measures according to the specific situation to achieve the best effect.
