Optimization measures for the structure of automobile cover stamping dies
1. Optimization of standard parts design for automobile cover stamping dies
At present, my country's standard parts design technology is tending towards an all-round development direction, and the design and application of standard parts have also been rapidly improved, thus promoting the gradual improvement of product quality. Since the optimization of standard parts design can improve its performance, it is helpful for the secondary use of mold standard parts, effectively reduce the cost of product production, and shorten the product processing and manufacturing cycle, so it is necessary to pay attention to the design optimization of standard parts.
First of all, since the design of standard parts for automobile cover stamping dies mainly emphasizes the standardization of design, all departments of the enterprise need to clarify the standard parts design standards, analyze and improve the past standard parts design standards, and develop new standard parts products with new structure, strong performance, low cost, good quality and high efficiency, so as to effectively promote the improvement of enterprise benefits.
Secondly, in the manufacturing process of automobile cover stamping die standard parts, it is necessary to strictly abide by the relevant manufacturing standards, pay attention to the overall performance of mold standard parts, and ensure the overall quality of standard parts products. At the same time, automobile cover stamping die enterprises need to effectively unite related industries to promote the research and development of automobile cover stamping die standard parts to a deeper level.
Finally, automobile cover stamping die standard parts need to develop in the direction of specialization and scale. Through the implementation of specialized production, mold standard parts enterprises can effectively activate the potential for enterprise development, win market competitive advantages for enterprises, and bring sustainable and stable development prospects for enterprises. At the same time, mold standard parts enterprises implement large-scale production, apply advanced equipment and science and technology, and recruit practitioners with strong professional capabilities to ensure the output scale and product quality of standard parts.
2. Design optimization of automobile cover stamping die parametric system
In recent years, my country's automobile cover stamping die parametric system has gradually tended to overall planning, mainly including three components: assembly model parameter library, part parameter library and model management library.
First, for the design of the mold assembly model parameter library, when the designer directly applies the previously designed assembly model, it is necessary to flexibly modify the parameters and structure according to the actual situation. At the same time, the designer can use UG technology to associate parameters (as shown in Figure 2), so as to guide the mold assembly model to achieve automatic update as a whole.
Secondly, for the design of the automotive cover stamping die parts parameter library, after the mold assembly work is completed, all parts and related parameters in the mold composition are important components of the mold parts parameter library. At the same time, these parts and related parameters are also an indispensable part of the mold assembly model parameter library. Since the mold assembly often adopts a top-down design method, the design of the automotive cover stamping die parts parameter library should be comprehensive and take all factors into consideration for a comprehensive design, so as to ensure that the mold parts parameter library plays a guiding role.
Finally, regarding the design of the model management library, it covers a large amount of information such as mold attributes, technical conditions, numbers and names, so the construction and management of the model management library can be carried out with the help of information technology, such as using information technology operations such as search, create and delete. At the same time, the required model in the model management library can be called and modified to the target model.
3. Design optimization of hot stamping die for high-strength sheet metal
First, in terms of the design of die materials, hot stamping die for high-strength sheet metal has higher requirements on manufacturing materials than cold stamping die. It is necessary to select materials with strong fatigue resistance, good wear resistance, high hardness and strength to ensure the accuracy of the die after forming. At the same time, when designing the material of hot stamping die for high-strength sheet metal, it is necessary to fully consider the heating temperature of the die and select the die steel suitable for use under heating conditions to ensure the performance and accuracy of the die after processing and forming.
Secondly, regarding the design of the concave and convex dies of hot stamping die for high-strength sheet metal, since the die involves heating and cooling in processing and manufacturing, thermal expansion and contraction can easily lead to errors in the size of the die parts after stamping. Therefore, when designing the concave and convex dies for the die, it is necessary to fully consider the thermal expansion and contraction factors and minimize the errors as much as possible to ensure the accuracy of the die parts.
Finally, regarding the design of the die cooling mechanism, since the hot stamping die must undergo cooling treatment before it can be produced, it is necessary to select a suitable cooling mechanism. When selecting a cooling mechanism, it is necessary to consider the cooling speed and strength of the mold parts, and also to prevent the mold parts from cooling too quickly and causing cracking.
