How to reduce the cost of automotive stamping dies?

　1.Current status of automotive stamping dies

With the development of the automotive industry and the widespread application of computer technology in the automotive stamping die industry, as well as the rapid development of automatic presses and inspection and scanning equipment, these favorable conditions provide convenience for development and improvement. Automobile stamping dies. With the progress and development of science and technology, in today's automobile industry, manual single-pass die has been gradually eliminated in the automobile manufacturing industry. At present, the dies used in the automobile manufacturing industry are gradually developing towards integration and automation, and are becoming more and more complex. At the same time, with the rapid renewal of automobiles and the reduction of production costs, the development of automobile stamping dies is gradually accelerating, and development costs need to be further reduced along with the requirements of the current form. In summary, it is necessary to continue to improve the manufacturing method of automobile stamping dies to reduce costs while improving quality.

　　2 Measures to reduce the cost of automotive stamping dies

2.1 Pre-stamping process optimization

Stamping process simulation technology can optimize the manufacturing process of automobile molds and effectively reduce costs. The application of cae technology can not only judge the performance of stamping parts in advance, but also accurately judge the defects of stamping parts, and provide technical support for formulating plans, thereby reducing the scrap rate in the process. At the same time, it also measures the deformation and deformation of the stamping parts to provide data for the technicians. In this way, the manufacturing process of stamping parts can be significantly optimized and simplified, and the operation and debugging cycle of stamping parts can be greatly shortened. The wide application of stamping process simulation technology can effectively reduce the development cost of automotive stamping dies.

The compression process and reducing the number of die sleeves can also reduce the development cost of automotive stamping dies. The stamping process can be appropriately optimized by applying stamping process simulation technology. At the same time, according to the different properties and specific conditions of the parts, different molds are used to optimize the structure and improve the utilization rate of automotive stamping die materials. Reducing stamping tools in the automobile manufacturing process can not only reduce the number of molds, but also reduce production, storage, and transportation costs, and improve production efficiency.

We can also learn from past experience to achieve the goal of reducing costs. Drawing on previous experience in die manufacturing, die designers can not only shorten the time for die process formulation, but also focus on the key aspects of die manufacturing, optimize die structure, and improve design efficiency. In addition, die designers can prevent possible problems in the manufacturing process in advance based on previous experience, and to a large extent avoid possible errors in the manufacturing process. By saving time and reducing errors, the manufacturing cost of stamping dies can be reduced.

　2.2 Mold structure optimization

First, optimize the mold structure by selecting the most suitable material. In the manufacturing process, we should start with the material of the mold. Only by fully improving the utilization rate of materials can we reduce unnecessary waste in materials and reduce costs. At present, automotive stamping die materials are generally divided into three categories: standard parts, forgings and castings. Taking into account the different types of stamping parts required, automotive stamping equipment, processes, and automotive output, materials that can save money to the maximum and meet demand should be selected. Under the premise of meeting production standards, automobile manufacturers often choose lower-grade materials when choosing automobile die materials. If you want to minimize costs, you need to plan from the beginning to reduce unnecessary waste and avoid exceeding expectations. At the same time, in the case of large output, alternative materials must be selected to quickly repair or replace damaged automobile stamping dies to avoid unnecessary waste. In short, in the selection of automotive stamping die materials, various factors should be comprehensively considered to maximize the use of materials, so as to reduce the manufacturing cost of automotive stamping die materials.

In the mold development process, the process arrangement must make the mold structure design simple and practical. The design of automobile stamping dies should be based on the original parts required for stamping. The specific reference value is the number of required parts and the accuracy of the required parts. In the design, in addition to adopting traditional optimization measures (such as simplifying the guiding method) and reducing the weight of the mold, the most advanced optimization measures at this stage can also be adopted. For example, computer simulation technology can provide performance simulation and verification reference for automotive stamping die structure design. When using computer simulation technology to design the mold structure, the automotive die designer can easily check the structural strength of the automotive die. This can not only ensure the performance of the mold, but also minimize the use of materials and achieve the effect of reducing costs.

　　2.3 Reduce mold processing costs

Since machining will directly affect the manufacturing cost of automobile die, machining is particularly important in the manufacturing process of automobile die. First of all, we need to know the performance and usage of each part of the required mold. Once the performance of the required mold is known, the accuracy of the mold can be determined, and then a reasonable process can be formulated according to the actual situation. Choose the most suitable tool according to the required accuracy to optimize the machining process. In order to further reduce the cost of the production process, we can reasonably manufacture and arrange production according to the current equipment status and the company's capital status. According to the actual situation, the order and steps of quenching and finishing were determined, and automobile stamping dies were manufactured reasonably.

3. Concluding remarks

In order to achieve the goal of minimizing the cost in the production process of automobile die, the automobile manufacturing industry must optimize and improve the preliminary design, manufacturing process, and comprehensive performance debugging after production. Reducing the cost of automobile stamping dies in the production and manufacturing can enable enterprises to maintain their competitiveness in the market and not be eliminated by the times.
