With the continuous development of my country's industry, the industrial economy accounts for an increasing proportion of my country's economic structure, and its role in promoting the development of my country's national economy has become more and more significant. In the industry, automobile manufacturing is an important part of it. With the rapid development of social economy and the improvement of people’s economic living standards, it is becoming more and more common for people to buy their own cars and use them for travel. This is such a society. Under the background of supply and demand, my country's automobile consumption has shown a trend of blowout growth in recent years. While automobiles provide great convenience for people's daily work, they are becoming more and more popular among people. As a result, my country’s automobile manufacturing has also achieved considerable development driven by social demand, not only in terms of automobile productivity and production efficiency, but also as my country increases its investment in research on key automobile production technologies such as automobile engines. my country’s automobile production technology has also made a qualitative leap, which has led to a huge improvement in the production quality of my country’s automobiles. The development of automobile production has contributed to the promotion of my country’s urbanization process and the healthy and sustainable development of my country’s social economy. , Has an important role. However, with the continuous development of automobiles, its existing problems continue to emerge. Among them, the consumption of metal materials in the production process remains high, and the problem of low utilization of metal materials is more serious, especially in the manufacturing of automobile stamping equipment. Among them, the consumption of metal is huge, which affects the reduction of automobile manufacturing costs and hinders the overall improvement of automobile production efficiency. Therefore, it is of positive significance to increase the relevant research on the process and methods of the metal material utilization rate of automobile stamping parts.


1. Optimize product design




In order to improve the utilization rate of metal materials of automobile stamping parts, the structure of the product should be optimized first to fully reflect its manufacturability and improve the economic efficiency of its design. In product design, the actual conditions of the parts required for automotive stampings and their structural composition should be fully considered, and the design of its various parts should be optimized from an overall perspective, so that it can save metal materials to a greater extent. For some product parts with low utilization rate of metal materials, relevant designers need to research and improve them, design parts with high utilization rate of metal materials, and then combine the optimized parts to obtain the utilization rate of metal materials. Automotive stamping products. In addition, the staff must strengthen the review of the processability of the products and the economic benefits of the products, so as not to reduce the quality of the products, but also to reduce the production cost of automotive stamping parts and improve the overall economic benefits of automotive manufacturing.




2. Choose a reasonable process method




In order to improve the utilization rate of metal materials of automobile stamping parts, a reasonable process method is also selected. When producing automobile stamping parts, we must first select materials reasonably, and then select reasonable processing methods according to the actual conditions of the materials used and the product quality requirements, and improve the utilization efficiency of metal materials under the premise of product quality. Specifically, it mainly includes the following aspects: First, it is preferred to choose less and no waste blanking. After clarifying the product design plan, in terms of material selection, we should choose those with little and no waste as much as possible for blanking. If such materials are difficult to meet the requirements of the product structure, relevant designers can improve and optimize the product structure according to the actual situation of such materials, so as to greatly increase the utilization rate of materials. The second is to clarify the process layout. When designing the product process method, a variety of situations should be fully considered, a number of plans should be designed in advance, comparisons should be made, and a better layout plan should be selected from them. When calculating the blanking and lap edges, it is necessary to design the thickness of the thin plate laps to be more than three millimeters in combination with the current level of my country’s actual production and manufacturing of automobile stamping parts. At the same time, the thickness of the thick plate laps must be Exceed the material thickness; the third is the reasonable application of the cutting method. When designing the production process of automotive stamping products, it is necessary to fully consider the specifications, dimensions, shape and other characteristics of the parts and materials used. In the remaining material area of the parts, implement the cutting process to obtain another part, and then The remaining material of this part is cut off, so that two parts can be obtained. In this way, not only can work efficiency be improved, working hours can be shortened, but also the utilization rate of materials can be improved, 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. The selected uncoiling line




In order to improve the utilization rate of metal materials of automobile stamping parts, the uncoiling line is also selected. In terms of the production and manufacturing of thin steel plates, my country’s GB708-88 standard stipulates that its length is several multiples of 50mm, and its width is several multiples of 10mm. It is also based on this regulation that in the cutting layout design of parts, material waste is prone to occur, and the utilization rate of materials is not high. To deal with this situation, an uncoiling cutting line can be used to solve this problem. Because this uncoiling line not only has the advantage of being affordable, but also in terms of the accuracy of the blanking size, it can improve the stamping of automobiles. The utilization rate of metal materials in the production process of each product. It is also based on the excellent characteristics of the uncoiling line that the uncoiling line has been widely used in the blanking process of my country's automobile production and has achieved remarkable results in improving the utilization of materials.




4. Prefer plastic parts




In order to improve the utilization rate of metal materials of automobile stamping parts, plastic parts can be preferentially used in the selection of materials for non-stressed parts and decorative parts. With the continuous improvement of the level of automobile production and manufacturing technology, consumers' requirements for the appearance of automobiles have increased sharply, and the design of non-stressed objects such as automobile decoration parts has also put forward requirements, and because of such automobile objects , Its shape is more complicated, and its processing is also more difficult, so it will cause a large amount of material loss in the manufacturing process, resulting in an increase in automobile production costs. In view of this situation, plastic materials can be used to replace metal materials, which not only improves the beauty and quality of the car, but also improves the utilization rate of the material and reduces the production cost of the car. For example, in the production and manufacturing of automobile radiator masks, the utilization rate of its metal materials is less than 60%. After the stamping parts are transformed into plastic parts, it not only improves the decorative beauty of the car, but also reduces the cost of the stamping parts. The production cost improves the economic efficiency of automobile production. In addition, by improving the production process of stamping parts to reduce the scrap rate, it is also a process method to increase the utilization rate of metal materials.




It can be seen from the above that in the production of automobile stamping parts, a large amount of metal materials need to be consumed. At the same time, the current material utilization efficiency is not high, which increases automobile production costs and is not conducive to the healthy and long-term development of automobiles. The relevant research on the process method of the metal material utilization rate of automobile stamping parts is of far-reaching significance.
