1. Foreword At present, in a large number of parts manufacturing enterprises, especially the automotive parts industry, stamping technology is widely used in the production process of sheet metal. The parts produced by the stamping process will spring back as the pressure is removed, resulting in different dimensions from the design and quality defects. Especially when the rebound amount is too large, it will not only affect the quality of the part, but also have a huge impact on the assembly. At present, most companies gradually begin to introduce CAE simulation links to simulate stamping and springback processes. The traditional method is to use LS-DYNA for explicit-implicit analysis, but this method is based on the classic interface and requires users to have deep knowledge of finite element theory. , And proficient in command flow, but also need to have sufficient understanding of k files, so customers using this module for stamping simulation and rebound have brought a lot of obstacles. In view of this phenomenon, this paper introduces a method based on the Workbench platform using Explicit-Str module for explicit dynamics and stamping process analysis, and Mechanical module for implicit analysis and springback analysis. Using this method does not require users to master a lot of Classic interface operation, while greatly improving the simulation efficiency and ease of use without affecting the accuracy. 2. Theoretical foundation of stamping and springback process simulation The stamping springback simulation is usually divided into two processes: stamping process simulation (loading) and springback process simulation (unloading). Generally, an explicit algorithm is used to calculate the stamping process, and an implicit algorithm is used to calculate the rebound process.

The use of laser welding technology can reduce the volume of automotive transmission gears, simplify product structures and manufacturing processes, and improve production efficiency. The principle, characteristics, equipment composition, welding process and quality of gear laser welding are briefly described. At present, the application of this technology mainly depends on the cost performance of the laser. Welding quality can be controlled by testing the surface and micro conditions of the weld, weld strength, gear torque, etc. In the design and manufacture of gears for automotive transmissions, in order to reduce the difficulty of cold and hot processing of gears and improve production efficiency, gears are often divided into two separate parts and processed separately, and then the two parts are combined together to form a whole. The composite gear is also called a gear assembly, such as a gear assembly composed of gears and cones (engaging teeth). There are two main ways to connect compound gears: spline connection and beam welding connection. The spline connection is achieved by internal and external splines. The empty sipe is large, the gear axial size is large, and the production efficiency is low. The beam welding connection is mainly electron beam welding and laser welding. It is a smooth cylindrical fit connection. Instead of the spline connection, the empty sipe is reduced, the gear volume is reduced, the vehicle weight is reduced, and the production efficiency is significantly improved. Among them, the transmission gear laser welding technology has developed rapidly, and it is also an important technology for laser processing. The use of laser welding technology to connect the gear assembly can improve the product accuracy of transmission gears, simplify the product structure and manufacturing process, and conveniently meet the needs of continuous adjustment of component structures and prototype manufacturing during product development and trial production.

Advantages of laser welding: beautiful appearance, no deformation of parts in mass production, no post-processing required. Narrow and deep welds are the hallmark of laser welding. The laser weld penetrates deeply into the metal. Its energy melts the edges of the part, and a small amount of metal creates a molten pool and forms a weld. The welding head irradiates the laser onto the workpiece and melts it. Since the laser spot diameter is only a few tenths of a millimeter, it is a high-precision tool. Preetz provides not only laser welding heads but also corresponding online and offline welding inspection systems. The seam tracking system guides the welding head to achieve precise welding and check the welding results. The scope of application of laser welding goes far beyond ordinary welding-both in the choice of material and the application itself. The laser can weld steel, stainless steel, non-ferrous metals and plastics, and can also be used for brazing and cladding. Preetz supplies the corresponding parts. Deep penetration welding is the result of huge laser energy focused on one point. With a laser energy of up to one megawatt per square centimeter, the laser hitting the metal quickly vaporizes it. This process is also called the pore effect. The vaporized laser beam penetrates into the metal. The laser beam melts the metal around the suction hole, and then the weld pool forms a weld. Due to the low linear energy, very little heat enters the part. Parts are not easily deformed and do not require post-processing, which is suitable for production. Although lasers are suitable for deep-fusion welding, they are also suitable for heat-conduction welding. In this application, the focal point of the laser is not used, and the width of the melting area is usually greater than the depth. In addition to visible weld production, laser
In the mysterious automobile manufacturing rivers and lakes, five legends about laser welding have been circulating. Welcome to today's "Into the Science-" The Five Legends of Laser Welding in "Jianghu" ", take you to discover the legend! Myth 1: Laser welding is more powerful than resistance spot welding. Resistance spot welding on automobiles is the most commonly used welding method. It has been criticized for its prone to splashing and poor aesthetics. Laser welding is not the case. Can give you a beautiful weld in minutes. Is it so pleasant to draw a conclusion? The competition between the two can be more than this in production: Despite the above problems, welding strength may be more interesting to us. Compared to resistance welding, which has so few welding spots, the long welding seam of laser welding makes people feel more solid. In fact, the tensile strength of laser welding is affected by factors such as the length of the weld and the width of the weld. The tensile strength of spot welding is also related to factors such as the number and spacing of the welding points. Although laser welding does have an advantage in increasing the upper limit of strength, considering the actual production situation, the two are not significantly comparable in strength. However, it is undeniable that laser welding has an advantage in improving rigidity, especially in improving NVH, because it improves the fit between the plates and the weld consistency is better. Myth 2: Laser welding uses only lasers to talk about lasers, and some people immediately think of the cool "dance knife and sword" in Star Wars. However, the truth is that it's just a lightsaber, and the laser won't stay in the air for more than a meter.

0 Introduction With the rapid development of the automotive industry, people have higher and higher requirements for automobiles. People not only pay attention to the safety performance and functions of the entire vehicle, but also have a more refined perception of the appearance. The fuel tank cap of a car is generally located above the rear wheel cover of a passenger car, on the same side as the fuel tank. Its main function is to decorate the body. Often, a small detail of the fuel tank cap will determine a person's intention to buy a car. This article analyzes the common quality problems of SUV or car fuel tank cover painting and the coating process schemes adopted. 1 Introduction to the structure of the fuel tank cap The fuel tank cap structure in the eyes of painting practitioners can be roughly divided into two types. One is a metal fuel tank cap. The material of the fuel tank cap is generally iron, which has strong stability, and requires electrophoresis and spray painting. One type is the plastic fuel tank cap. The material of the fuel tank cap is high temperature resistant polymer plastic, which has low quality and strong rust resistance, and only needs to be painted. Due to the different materials of the fuel tank cap, the coating process of the fuel tank cap will be completely different, and there will be different coating schemes. 2 Requirements for the coating process of the fuel tank cap structure 2.1 Requirements for the coating process of the metal fuel tank cap structure For the metal fuel tank cap structure, if a specific fuel cap coating process scheme is not identified and given in the initial design, but Choosing the conventional on-vehicle painting will result in electrophoretic flow paint, surface spraying, difficult spraying and flow paint. In order to obtain better quality of the fuel tank cap, the analysis is combined with the practical experience of the production line of a coating workshop of our company. 2.1.1 Quality analysis of metal fuel tank caps

Today, when consumers buy a car, in addition to performance and configuration considerations, another important consideration is the appearance of the car. A large part of the car will pay attention to the color of the car. The color of the car is also like clothing, it will have different popular colors, but the popular color of the car is relatively long, with time, regional and hierarchical. According to Axalta Coatings' 2018 Global Automotive Color Popularity Report data, since 2011, white has continued to be popular and has become the most popular color among automotive buyers worldwide. In addition to the mainstream monochrome body, from the 2019 Shanghai Auto Show, it can be found that the two-color combination body color has become one of the most car buying trends that consumers are most concerned about because it looks more dynamic and stylish. As the process advances, body painting can already be customized. The earliest represented by the small cars Mini Couper and Fabia, the unique two-color body configuration makes the overall shape more stylish and beautiful. In recent years, many car companies have launched their own two-color product cars, and there will still be new two-color models in the next few years. The popularity of two-color bodywork also has a greater relationship with the region. The future two-color body will be mainly concentrated in Asia and Europe, and the proportion of the two regions will be as high as 85%. Judging from the current domestic situation, more than half of the auto companies at this year's auto show showed their two-color cars, especially the two-color SUVs, which have received a lot of attention from consumers. The number of two-color models is also increasing in the future, and the output of two-color vehicles is also increasing. For the passenger car market, two colors
Introduction Aluminum alloy vehicles, as a development direction of lightweight logistics vehicles, have increased to a large extent in recent years. However, the appearance effect of the aluminum alloy surface oxide film has deteriorated over time due to the problem of the oxide film on the aluminum alloy surface. The change from steel to aluminum alloy, in order to better decoration and prevent oxidation and corrosion, the type and quality of coatings have also changed greatly. It is a convenient and more environmentally friendly solution developed in recent years to further inhibit the formation of oxide films by water-based polyurethane coatings and achieve decorative and aesthetic appearance. Water-based polyurethane uses water as a solvent. Compared with traditional solvent-based polyurethane, it has the advantages of no pollution, safety and reliability, and excellent mechanical properties. With the further improvement of national environmental protection requirements, especially the control of organic volatile matter (VOC) emissions, following Beijing, Guangzhou, Tianjin, Hebei and other relevant provinces and cities have all issued the "Volatile Organic Compound Emissions from Industrial Enterprises "Control Standards" and other corresponding management methods for controlling VOCs, so waterborne coating products, as a branch of the development direction of low VOC products, have greater market potential. This experiment is designed for aluminum alloy logistics vehicles developed by an automobile company. Develop an environmentally friendly water-based polyurethane product with good adhesion and weather resistance. 1 Test section 1.1 Raw materials The main raw materials used in this experiment, related indicators and technical parameters are shown in Table 1: Table 1 Main raw materials for preparing water-based polyurethane 1.2 Coating preparation
