Methods for cost reduction and optimization of raw materials for automotive stam
At present, automobile companies are facing huge market competition, and the automobile industry is in a market environment where supply exceeds demand. In order to occupy market share in the fierce market, automobile companies continuously reduce sales prices, compress their operating profits, and ultimately lead to many automobile companies going bankrupt due to vicious competition. People are paying more and more attention to environmental issues. As a means of transportation, the manufacture of cars not only requires a large amount of natural resources, but also causes great harm to the environment during their use. Therefore, people have concerns about the use of cars, which has affected the development of China's automotive industry. Faced with such a severe external environment, in order for automotive companies to achieve long-term stable development, they need to strengthen internal management and reduce production costs on the basis of quality. In the production cost of automobiles, the cost of automotive stamping parts raw materials occupies a dominant position. Therefore, automotive companies need to strengthen cost management for automotive stamping parts raw materials and adopt optimization measures to reduce their costs.
Methods for cost reduction and optimization of raw materials for automotive stamping parts
1. Optimize the design of stamping die technology
The design of stamping dies for automotive stamping parts directly affects the utilization of stamping raw materials, and plays a very important role in maintaining the quantity of stamping raw materials. Therefore, automobile companies need to consider the issue of raw materials when designing stamping dies, and continuously optimize the design of stamping die processes from the perspective of saving raw materials. The specific method is as follows:
(1) Change the shape of stamped parts
Most of the current automotive stamping parts use square molds, which is not only detrimental to saving raw materials, but also to the aesthetics of the car. If a trapezoidal mold is used, it can not only save a lot of raw materials, but also make the car look beautiful.
(2) Using computers to sort parts
Under the traditional parts sorting method, many automotive components cannot be connected together, and once the parts cannot be used, it is also a form of waste of raw materials. If a computer is used to sort the parts, the connection error between the components will be significantly reduced, resulting in less waste of raw materials.
(3) Increase the utilization rate of material dropping
Regardless of the shape of the model used for automotive stamping parts, there will always be some material scraps. How to utilize these scraps plays an important role in the management of stamping raw materials for automotive enterprises. If automobile companies can use scrap materials to manufacture smaller car parts, the effect of reducing raw material costs will be strengthened.
2. Reduce the business negotiation cost of automobile enterprises
In the cost structure of automobile enterprises, the proportion of procurement costs accounts for 170%, and the bargaining power of automobile enterprises is important for their costs. Therefore, in the process of cost management, enterprises should attach great importance to the ability to provide opinions, minimize bargaining costs, and minimize the cost of stamping raw materials for automotive enterprises. Specific reduction methods can be carried out from the following aspects:
(1) Establish sound data support
The procurement department of automobile enterprises should conduct in-depth research on the suppliers of various automobile stamping raw materials, understand their product performance, quality, and price, compare different suppliers of a product, find the differences, and improve the business bargaining power of automobile enterprises through sound data support, reducing the bargaining cost of enterprises. In addition, automobile companies should also choose the appropriate timing to purchase raw materials based on market changes and the cost of raw materials for the enterprise.
(2) Using standardized procurement to control business negotiation costs
It is difficult to fix the procurement cost in a specific way. On the one hand, market prices change in real time, and on the other hand, differences in product quality and suppliers can also cause differences in product prices. Therefore, automobile companies are prone to differences in the process of purchasing raw materials. Adopting standardized procurement methods can minimize product procurement differences, implement standardization of raw material specifications, and achieve the ultimate goal of cost reduction through economies of scale.
The planned stamping parts have a simple shape and reasonable structure, which is conducive to simplifying the mold structure and reducing the number of processes. Only in this way can the entire part be processed with fewer and simpler stamping processes, reducing the need for other methods of processing, and facilitating stamping operations, making it easier to arrange and complete mechanized and automated production, thereby improving labor productivity.
Of course, the planned stamping parts also have satisfactory product application and skill functions, and can be easily assembled and repaired. Working together is beneficial for utilizing existing equipment, process equipment, and workflow to process it as much as possible, and for extending the service life of the stamping die.
In addition, the planned stamping parts should have lower requirements for scale accuracy level and surface roughness level as much as possible under normal operating conditions, which is conducive to product exchange, reducing waste, ensuring product quality stability, reducing costs, and improving value. No matter where the stamped parts produced by planning are used, it is necessary to strictly follow the corresponding guidelines to plan the stamped parts, so as to achieve energy-saving and other intentions while ensuring product quality.
So what are the planning criteria for stamping parts? Planned stamping parts are beneficial for improving the utilization rate of metal materials, reducing the types and standards of materials, and minimizing the consumption of materials as much as possible. If agreed, low-cost materials can be used to manufacture stamping parts, striving to achieve zero waste and minimal waste cutting of the parts.
Regarding the processing of small stamping parts, it is prohibited for the operator's fingers, wrists, or other parts of the body to enter the mold area for operation. The mold planning should indicate the mold weight on the overall drawing for easy installation,. Parts weighing over 20 kilograms should be processed with lifting transfer methods to reduce labor intensity. When assembling and disassembling mold parts, it should be convenient to prevent the possibility of pinching or cutting hands, and the mold should be easy to collapse and store.
It is not allowed to produce waste or workpiece missiles during the processing of stamped parts, which may affect the operator's attention or even injure them. Excessive and difficult actions are not allowed during homework. Efforts should be made to prevent intense noise and oscillation during stamping processing. The various parts on the mold should have sufficient strength and rigidity to prevent damage and deformation during use. The fastening parts should have anti loosening measures to prevent accidental damage to the operator. To prevent burrs on stamped parts from cutting hands.
Operators are not allowed to have excessive movements during stamping operations to prevent the body from losing a stable posture. In general, even delicate issues in the mold can affect it. Only by analyzing the specific problems in each operation can precautions be proposed for stamping parts in the mold.
Clean the surface of the outer covering with clean gauze. The inspector needs to wear contact gloves and make contact with the outer surface of the stamped part along the longitudinal direction of the stamped part. This inspection method depends on the inspector's experience. Oil stones can be used to polish the suspicious area being detected and verify it, but this method is still an effective inspection method.
