汽车钣金是一种汽车修复技术,意思就是把将汽车金属外壳变形部分进行修复的加工工艺。汽车钣金也等于汽车钣金修理,指汽车发生碰撞后要对车身进行修复,即除对车身进行防腐和装饰的喷涂工作外其余的所有工作。
由于汽车是一个高精度的整体,并且电器配件、机械配件都要以高精度低误差依附于车体的相应位置。
甚至于车漆的直曲线性也要高度依赖车体钣金的误差值,所以钣金车体以及修复,成为了汽车行业一个无硬性标准,无自动工具,无法直观传授的纯手工工种。
汽车钣金:
1、汽车钣金是一个汽车修理的技术手段,此方面汽车钣金等于汽车钣金修理,指汽车发生碰撞后要对车身进行修复,也即除对车身进行防腐和装饰的喷涂工作外其余的所有工作。
如汽车车身损伤的分析,汽车车身的测量,汽车车身钣金的整形,拉伸矫正,去应力焊接,以及汽车车身附件装配,调整等工作。
2、汽车钣金就是汽车维修的一种加工方法,又叫冷做,说直接点,如果车身外观损坏变形,就需要钣金这个工序。汽车碰撞修复已经由原始的“砸拉焊补”发展成为车身二次制造装配。
3、碰撞事故车辆的修复不再是简单的汽车钣金的敲敲打打,修复的质量也不能单靠肉眼去观察车辆的外观、缝隙。维修人员不但要了解车身的技术参数和外型尺寸,更要掌握车身材料特性,受力的特性的传递车身变形趋势和受力点以及车身的生产工艺如焊接工艺等。
4、钣金是汽修的一个工种,主要是针对车身外观的,对外车体(例如保险杠,车门)的更换,修复,矫形,烤漆也属于钣金工区,钣金内还有具体分工,广义的钣金以上内容全涵盖。
5、而狭义的钣金只是更换外车体,以及利用焊接,上架矫形等大体修复车形工作,广义下的钣金还有打腻子,打磨的,以及喷漆的,还有抛光的,在内部都是各自分工,我们所说的钣金,一般是指广义上的

在汽车制造和维修,许多钣金结构件的形状是非常复杂的,为了避免板材的困难,薄板金属材料必须具有良好的工艺性能要求,即:
1、钣金材料必须有很好的塑性。要有在外力作用下产生永久变形而不被破坏的能力。对于冷作零件来讲,要有良好的冷塑性,如汽车零件冲压件;对于热作零件来讲,要有良好的热塑性,如热锻件弹簧钢板、热铆钉等;
2、良好的可焊性。许多汽车钣金零件是通过点焊、氧焊、弧焊或气体保护焊等方式熔焊在一起的,所以要求钣金零件必须有良好的焊接性能。这一点在汽车挖补维修中尤其重要,可焊性好的材料焊接强度高、开裂倾向小;
3、价格低廉,经济实用。对于汽车的任何构件,在满足工作条件的情况下,都应考虑到经济性。能用黑色金属的,不用有色金属;能用有色金属的,绝不用贵重金属。汽车钣金构件的寿命,应该与汽车其他构件的寿命相适应;
4、良好的化学稳定性。汽车覆盖件大都是在露天环境中工作的,经常与水及蒸汽接触,特别像消声器,经常在较高温度和腐蚀气体下工作。这就要求钣金零件必须有良好的化学稳定性,既要求在常温下耐腐蚀,防锈能力强,又要求在高温或太阳暴晒下不被腐蚀,不变形;
5、良好的板材的尺寸精度和内在质量。板材的尺寸精度和内在质量对钣金加工影响极大,特别是对模压件影响更大。
汽车钣金组装我个人理解是指焊装车间的工作内容,不包括涂装和总装,也不含零部件,零部件的钣金应叫钣金制作;钣金组装是指焊装车身部分的两侧,地板,车门,引擎盖,行李仓盖,等等,将他们焊接或装配在一起,形成一个完整的车壳,这个过程称作钣金组装。
汽车喷漆,是一种汽车美容手段,是指给汽车表面上一层漆达到保护汽车的作用。汽车底漆又叫防锈底漆,即底涂层用漆,它一般直接涂覆于物体表面或涂于腻子表面。它的作用是防止金属表面氧化腐蚀,增强金属表面与腻子或中间涂层、面漆的附着力。所以简单总结就是,如果你的车身有外观损坏和变形,就需要汽车钣金。如果只是单纯的想增强汽车的耐磨耐腐蚀性能,就可以选择喷漆。
汽车的钣金件,一般是指汽车的金属外壳,它通常是用钢板制成的,在保证有一定强度的基础上,尽量减轻重量是对它的基本要求
叶子板也叫翼子板,是遮盖车轮的车身外板,按照安装位置又分为前叶子板和后叶子板,作用是利用流体力学,减小风阻系数,让汽车行驶更加平稳。
前叶子板安装在前轮处,因为前轮有转向功能,所以必须要保证前轮转动时的最大极限空间,因此设计者会根据选定的轮胎型号尺寸,用车轮跳动图来验证翼子板的设计尺寸。

汽车钣金是汽车修理的一种技术手段,是指在碰撞后对车身进行修理,即除车身防腐和装饰喷涂外的所有其他工作。1.敲除修复法:对于小范围的局部凸起和凹陷,可以通过敲除法修复单个、小而浅的凸起和凹陷,使金属变形并恢复到原来的形状。
二、撬顶修复法:用刮平刀(或勺形板)和尖头工具(如各种镐)撬开顶部凹陷部分,使凹陷部分逐渐恢复原状。
3.拉伸修复法:用牵拉器将凹痕牵拉出来,这也是常用的凹痕整形方法之一。牵拉装置包括吸盘、牵拉缸和专用牵拉器。
