Effective process methods for improving the utilization rate of metal materials
With the continuous development of China's industry, the proportion of industrial economy in China's economic structure is also increasing, and its role in promoting the development of China's national economy is becoming more and more significant. In the industry, automobile production and manufacturing are important components. With the rapid development of the social economy and the improvement of people's economic living standards, the phenomenon of people purchasing cars for travel has become increasingly common. Against the backdrop of social supply and demand, China's automobile consumption has shown an explosive growth trend in recent years. While providing great convenience for people's daily life and work, automobiles are also becoming increasingly popular among people. As a result, driven by social demand, China's automobile production and manufacturing have also made significant progress. Not only has there been an improvement in automobile productivity and production efficiency, but with the increasing investment in key production technologies such as automobile engines, China's automobile production technology has also made a qualitative leap. This has greatly improved the production quality of automobiles in China. The development of automobile production plays an important role in promoting the process of urbanization and the healthy and sustainable development of China's social economy. However, with the continuous development of automobiles, their existing problems have also become increasingly apparent, especially the high consumption of metal materials and low utilization of metal materials in their production process. Especially in the manufacturing of automotive stamping equipment, the consumption of metal is huge, which affects the reduction of automotive production costs and hinders the overall improvement of automotive production efficiency. Therefore, increasing research on the process methods for the utilization of metal materials in automotive stamping parts has positive significance.
1. Optimize product design
To improve the utilization rate of metal materials in automotive stamping parts, the first step is to optimize the structure of the product, fully reflecting its processability while enhancing its design economy. In product design, full consideration should be given to the actual situation of the parts required for automotive stamping parts and their structural composition, and the design of each component should be optimized from a holistic perspective to maximize the savings of metal materials. For product parts with low utilization of some metal materials, relevant designers need to conduct research and improvement, design components with high utilization of metal materials, and then combine the optimized components to obtain automotive stamping parts with high utilization of metal materials. In addition, the staff also need to strengthen the process review of the product, while ensuring the economic benefits of the product, so as to reduce the production cost of automotive stamping parts and improve the overall economic benefits of automotive manufacturing without compromising product quality.
2. Choose a reasonable process method
To improve the utilization rate of metal materials for automotive stamping parts, it is also necessary to choose a reasonable process method. When producing automotive stamping parts, the first step is to select materials reasonably, and then choose processing techniques reasonably based on the actual situation of the materials used and their product quality requirements. Under the premise of product quality, the utilization efficiency of metal materials can be improved. Specifically, it mainly includes the following aspects: firstly, prioritizing the use of less and no waste punching. After clarifying the product design plan, in terms of material selection, it is advisable to choose those with minimal and no waste for punching. If such materials are difficult to meet the requirements of product structure, relevant designers can improve and optimize the product structure based on the actual situation of such materials, thereby maximizing the utilization rate of materials. The second is to clarify the process layout. When designing product process methods, multiple situations should be fully considered, and several schemes should be designed in advance for comparison, and the optimal layout scheme should be selected from them. When calculating the edge of the material, it is necessary to combine the actual technological level of China's current production and manufacturing of automotive stamping parts, and design the thickness of the thin plate edge to be more than three millimeters. At the same time, the thickness of the thick plate edge should exceed the material thickness; The third is to apply the cutting method reasonably. When designing the production process of automotive stamping parts, full consideration should be given to the specifications, dimensions, and shape characteristics of the parts materials used. In the residual material area of the parts, nesting processing should be carried out to obtain another part, and then the residual material of this part should be cut off to obtain two parts. In this way, not only can work efficiency be improved and working hours be shortened, but material utilization can also be increased, and the production efficiency of automotive stamping products can be improved. In addition, in the cutting and layout of materials, the nesting process can also be reasonably applied to improve the utilization rate of metal materials.
3. Selected unwinding line
To improve the utilization rate of metal materials for automotive stamping parts, an uncoiling line is also chosen. In the production and manufacturing of thin steel plates, China's GB708-88 standard specifies that the length is several multiples of 50mm, and the width is several multiples of 10mm. It is precisely based on this regulation that material waste is prone to occur in the cutting and layout design of parts, and the utilization rate of materials is not high. In response to this situation, an open cutting line can be used to solve this problem. Due to its affordable price and high precision in cutting dimensions, this open cutting line can improve the utilization rate of metal materials in the production process of automotive stamping products. It is precisely based on the excellent characteristics of this uncoiling line that the uncoiling line has been widely used in the cutting process of automobile production in China, and has achieved significant results in improving material utilization.
4. Prioritize the selection of plastic parts
To improve the utilization rate of metal materials for automotive stamping parts, plastic parts can be given priority in the selection of materials for non stress parts and decorative parts. With the continuous improvement of automobile production and manufacturing technology, consumers' demands for the external beauty of automobiles have sharply increased. In terms of the design of non stress objects such as decorative parts of automobiles, requirements have also been put forward. However, due to the complex shape and difficult processing of such automobile objects, they will cause a large amount of material loss during the production and manufacturing process, leading to an increase in automobile production costs. In response to this situation, plastic materials can be used instead of metal materials, which not only improves the appearance and quality of automobiles, but also increases the utilization rate of materials and reduces the production cost of automobiles. In the production and manufacturing of car water tank face shields, the utilization rate of metal materials is less than 60%. However, after transforming this stamped part into a plastic part, not only does it improve the decorative beauty of the car, but it also reduces the production cost of stamped parts and improves the economic efficiency of car production. In addition, improving the production process of stamping parts and reducing their scrap rate is also a process method to improve the utilization rate of metal materials.
From the above, it can be seen that in the production and manufacturing of automotive stamping parts, a large amount of metal materials are required, and the current material utilization efficiency is not high, which increases the production cost of automobiles and is not conducive to the healthy and long-term development of automobiles. Therefore, increasing research on process methods to improve the utilization rate of metal materials in automotive stamping parts has profound significance.
