** Foreword: **
In the process of modern automobile manufacturing, the design and manufacturing process of stamping mold molds is one of the key factors that determine the quality and cost control of the automotive body.Whether it is body coverage, structural parts, or interior parts, precision stamping molds are inseparable.Therefore, mastering the design points and manufacturing process of molds can not only improve the accuracy of the product, but also effectively reduce production costs.This article will focus on the design and manufacturing process of car stamping parts mold to help readers better understand this complex and vital manufacturing link.
** 1. Design points: Artistic art **
When designing car stamping parts, we must first ensure that it meets the requirements of ** size accuracy **, ** shape complexity **, and ** surface mass **.Due to the high requirements of the size and shape of automobile parts, designers must fully consider the physical characteristics of the material’s ** rebound **, ** stretching **, and ** deformed **.
– ** Material selection **: According to product needs, choose the appropriate mold material. Common high -carbon and high chromium steels such as CR12MOV are widely used for their good wear resistance and quenchtability.
– ** Bounce compensation **: Different materials will rebound to varying degrees after stamping.When designing, it is necessary to accurately calculate the rebound volume through computer simulation (such as AutoForm, DynaForm and other software), and the shape of its shape is ** anti -deformation compensation design **.
– ** La Yanjin Design **: The design of the pull Yanjin affects the flow of materials during stamping.A reasonable pull -to -tendon layout can effectively avoid the problems of ** wrinkle ** and ** cracking **, thereby ensuring the quality of the punching parts.
** 2. Manufacturing process: fine carved art **
The accuracy of mold manufacturing depends not only on excellent design, but also on reasonable processing.The manufacturing process includes rough processing, precision processing, thermal treatment, surface treatment and other steps. Each step is about the quality of the final product.
– ** CNC Machining (CNC) **: In modern mold manufacturing, CNC processing is the core link.Through efficient and accurate CNC machine tools, complex geometric shape processing can be completed.Machining accuracy usually requires a micron level ** to ensure the smoothness and size consistency of the mold cavity.
– ** Thermal treatment process **: In order to improve the life of the mold, after the mold rough is completed, it is usually necessary to perform ** quenching treatment **.The quenching mold has good hardness and abrasion resistance, but it also needs to reasonably control its toughness to avoid cracking.
– ** Surface treatment technology **: After fine processing of the mold surface, surface reinforcement is often required.Common are chrome -plated **, ** PVD coating **, etc. These technologies can effectively enhance the wear resistance and antioxidant of the mold surface, thereby extending the service life of the mold.
** 3. Case analysis: a model of a model hood, the outer board stamping mold design **
When designing the outer plate stamping mold of the hood of a certain model, the designer must first consider the ** thickness of the board **, ** material characteristics ** (such as the SPHC, SPCC level of the steel plate), and the ** forming process **.Due to the high surface quality requirements of the hood, any tiny defect will affect the appearance of the vehicle.
In order to avoid common problems such as ** surface depression and ** ripples **, the designer adopted high -precision three -dimensional model construction technology **, and used analog software to perform a series of ** stress strain analysis**.Through fine adjustment ** tension shape ** and ** mold gap **, the uneven flow of materials produced during the stamping process was successfully eliminated.In the manufacturing process of the mold, the ** Electric Spark Processing (EDM) ** is used for precision processing of complex curved surface, and it is combined with ** laser quenching technology ** to enhance the hardness of the mold surface.In the end, the mold achieved high -quality production of the outer shelter of the hood and met the technical requirements of the vehicle manufacturer.
** 4. Summary: **
Successfully designing and manufacturing car stamping parts is not only a manifestation of technical capabilities, but also the accumulation of production experience.The precision of the mold ** and ** durability ** directly determines the quality and production efficiency of the pressure parts, and the reasonable design and superb manufacturing process are the guarantee of the success of the mold.In the modern automotive industry, through continuous optimization of mold design and processing technology, it can not only improve the manufacturing level of the vehicle, but also effectively reduce production costs and enhance the market competitiveness of the enterprise.
Through this article, we hope that more people can understand the craftsmanship and technical charm behind the car stress parts mold, and also provide reference and inspiration for relevant practitioners.
