In the chassis, engine, transmission and other core parts, China automobile has long relied on foreign brands. After more than ten years of technology accumulation, the level of independent auto parts has been significantly improved, including the Great Wall, Chery, Chang'an and other mainstream automobile enterprises have independently developed core parts, and a number of models carried by them have also become popular.

Car stamping parts play an important role in car industry, so the raw materials are widely used in the production of stamping parts. Generally in the production of such stamping time, most of the use of cold stamping technology to produce or process. Because the use of cold stamping processing method in the production enterprises can meet the characteristics of a large variety of industrial products and a large number of products per unit time. Especially in the era of large-scale mechanized production, the processing method of cold stamping has been widely welcomed in large and small processing enterprises.

After the car sheet metal parts are taken for repair or repair, the next process is very important, that is, cleaning, do a good job of cleaning, and the car body is completely new. So how to clean it?

I believe that many car owners have encountered such problems. When they get up in the morning to drive, they find that the parts on the car are missing, which is a very helpless thing. Even if the vehicle has an anti-theft device, a ground lock is also installed, but it cannot prevent the loss of auto parts. Which auto parts are easy to be stolen?

汽车钣金件加工业的逐步形成和发展大大加快了制造业的发展。钣金加工配送方式打破了传统的简单购销运输方式，引入了加工配送理念，拓宽了视野，加速了传统机械制造与技术的融合。

Automobile sheet metal parts generally refer to the metal shell of automobile, which is usually made of steel plate. On the basis of ensuring certain strength, it is the basic requirement to reduce the weight as much as possible. In addition to the role of protection and beauty, automobile sheet metal parts are also the main carrier of automobile gas resistance. Therefore, the quality and service life of automobile sheet metal parts will not only affect the appearance of the automobile, but also increase the resistance of air to the automobile due to the quality and deformation, which will reduce its economy.

The manufacturer of rearview mirror folding device shall check whether the surface of parts is rusted. The surface of qualified spare parts has both a certain precision and a bright finish. The more important the spare parts are, the higher the precision, the more strict the anti rust and anti-corrosion of the packaging. Pay attention to inspection during purchase. If parts are found to have rust spots, mildew spots, or rubber parts are cracked or lose elasticity, or there is obvious turning tool pattern on the journal surface, they shall be replaced.

在现代市场经济条件下，汽车邮政市场企业与车主之间在时间，地点，信息，产品数量，产品品种，产品价格和产品使用上存在差异。只有通过某些分销渠道，才能以正确的价格和正确的方式，在正确的时间和地点将汽车售后市场生产的产品提供给大多数车主。因此，正确选择短期，快速，低成本，高效的产品分销渠道已成为汽车售后市场企业开拓市场的重要战略。

钛合金是一种特殊的功能材料，在医疗行业中与人类的生命和健康息息相关。钛接近人体骨骼，具有良好的生物相容性，对人体组织无副作用。由钛和钛合金制成的数百个金属部件，例如股骨头，肱骨，头骨，膝关节，肘关节，肩关节，掌指关节，颌骨和血管扩张器，夹板，假体和紧固螺钉植入人体后，汽车零件取得了良好的效果，受到了医学界的高度评价。

In the industrial field, different production processes will have a great impact on the performance of products. So, for stainless steel stamping processing, what are its processing characteristics and advantages? Next, automobile stamping parts manufacturers will analyze and answer this question, hoping to help you. First of all, for automobile parts processing, we need to choose different processing technologies according to different materials. If we want to process stainless steel stamping parts, we must reduce the loss of materials as much as possible to keep the original material properties. Only in the process of processing, the shape has been changed to make it meet our needs and meet the requirements of production standards.

1Check whether the trademark identification is complete. The quality of the original product's outer packing is good, the writing on the packing box is clear, and the overprint color is bright. The packing box and bag shall be marked with the product name, specification, model, quantity, registered trademark, factory name, address and telephone number, etc. some manufacturers shall also mark their own marks on the accessories. Some important parts such as generator, distributor, fuel injection pump, etc. are also equipped with operation manual, certificate of conformity and inspector's seal to guide the user to use and maintain correctly. When purchasing, you should carefully recognize it to prevent buying fake and inferior products.

汽车冲压件所用的材料与金属冲压件密切相关。金属冲压材料的性质直接影响金属冲压零件的质量和使用寿命，也可能影响生产成本。对材料进行金属冲压的基本要求是什么？

精密钣金的工艺设计主要包括冲裁件的工艺分析和冲裁工艺方案的确定。通过良好的加工性能和合理的工艺计划，我们可以使用较少的材料消耗，更少的工序数量和工作时间来获得稳定地满足要求的高质量结晶产品，并使模具结构简单，模具寿命高，从而可以减少人工和下料成本。

通过在压制面上放置拉延筋来调节和控制变形阻力是一种有效且有用的方法。拉延筋可以很好地调节物料的流动，使拉延过程中物料各部分的流动阻力均匀，使流入型腔的物料量适合工件的需要，并防止出现更多起皱现象并减少裂纹。

The automobile stamping die represents the generalization that can be classified into the basic figure. First, search whether there is a stamping die that is completely common with the generalization and can be rushed out with a stamping action in the stamping die library. If there is such a die, the stamping die set under "select stamping die" will be neglected, and the searched stamping die will be directly used.

对于汽车冲压件，由于它们是网站的产品和关键字，因此在学习要求方面，它们应该是全面而具体的。因此，涉及到的知识内容和相关的难题均不容忽视。因此，基于此，我们将立即开始进行操作以提高您的学习效率。

如果汽车零件的冲压过程是热冲压，则其带来的好处主要是实现汽车的轻量化，并有效提高冲压零件的强度。而且，它是在高温下形成的，因此它还具有精度高，成型性能好且没有回弹问题的优点。可以使用的汽车零件有防撞梁，安全零件和车身结构零件。

汽车不锈钢薄板零件通常是不锈钢薄板零件和耐酸钢的总称。不锈钢薄板零件是指对诸如大气，蒸汽和水之类的弱介质腐蚀的抵抗力，而耐酸钢是指对诸如酸，碱和盐之类的化学腐蚀性介质腐蚀的抵抗力的钢。不锈钢薄板零件在本世纪初问世，已有90多年的历史。

There are many sheet metal materials suitable for automotive stamping parts processing, which are widely used in the electronic and electrical industry, including: 1. Ordinary cold rolled sheet SPCC. SPCC refers to the continuous rolling of steel ingot into steel plate coil or sheet of required thickness by cold rolling mill. SPCC surface does not have any protection, so it is easy to be oxidized when exposed to the air, especially in the humid environment, the oxidation speed is accelerated, dark red rust appears, and the surface should be painted, electroplated or other protection during use.

The fitting degree of sheet metal parts during loading is also a key point to distinguish the quality of sheet metal parts. It will determine whether the final effect of loading is beautiful or not, and at the same time determine the difficulty of installation. Therefore, it is also a factor that many sheet metal maintenance technicians are very concerned about. If the fitting degree of sheet metal parts and the original car is low, such as the hole position cannot be aligned, the error of loading clearance and flatness is too large (the one-way tolerance of high-quality sheet metal parts in this respect should be controlled below 1.0mm), it can be basically judged that this is a non-conforming product from a small factory. Mr. Luo said that few car owners have noticed that a strong collision will cause slight deformation of the whole car body. At this time, if you install the sheet metal parts with large clearance, it will cause the car body to deform again, affecting the recovery of the damaged vehicle to its original appearance and quality.
