At present, most of our cars have sheet metal parts repair needs for reasons that can be summarized as the bending phenomenon, tearing phenomenon, and the repair when the crease situation occurs. For different repair situations, there are certain differences in the repair techniques. Most

目前我们大部分汽车都有钣金件维修需求,原因可以概括为出现弯曲现象、撕裂现象、出现裂纹情况时进行维修。针对不同的修复情况,修复技术存在一定的差异。汽车钣金件的维修需求大部分是由于外力对汽车的挤压和冲击造成的。

汽车钣金件折弯修复

The bending repair technique of automotive sheet metal parts is applied when the car is squeezed or hit by external forces, which makes the squeezed or hit parts or causes a certain area of more serious damage results; and requires accurate measurement of deformation area, damage and other data through observation or with the help of professional testing tools. In the repair process, the main use of the bracing method in the damaged parts of the repair, through the play of bracing and pulling the direction of the reverse force to repair the bending of the auto body sheet metal parts. However, in the process of utilizing the brace bit method, attention should be paid to the application of gap pads to reduce the damage to the auto body caused by the repairing behavior.

Tear Repair Of Automotive Sheet Metal Parts

在大多数情况下,修复汽车钣金零件的撕裂可能会导致钣金错位,在严重的情况下,会导致钣金丢失。修复时,需要2个步骤:压平,然后焊接。压扁工艺是对车辆钣金件的损伤部位进行预处理,损伤部位的修复是在氧焊的帮助下完成的。但是,在这个过程中,使用现代新型焊接设备CO2气焊会使受损部位的焊缝开口更加平整。如果焊缝存在延性凸起,则采用新的凹凸损伤修复方法对焊缝位置进行修复。在较严重的撕裂损坏的情况下,汽车钣金件的修复可以通过气刨或更换新零件来完成。

汽车钣金件的褶皱修复

汽车钣金件的褶皱修复是对发生弹性变形或塑性变形的损伤部位进行褶皱或凹面损伤的修复。判断汽车钣金件折叠损伤的表现形式是选择合适修复方法的依据,其中凹凸损伤可采用现代设备修复车身修复网片,并结合锤击法或拉动法修复。损坏的零件。轻微凹凸损伤的常用修复方法是在反面凹区最低位置用垫铁反复锤击修复损伤;而对于严重的凹凸损伤,则通过凹区背面的板垫进行修复,并对其进行支撑和拉动。因为大括号拉恢复需要更多大括号拉支撑,所以可以提前对凹位加热,并及时注意顶出的后果,分析回弹现象,使凹凸损伤修复完整。在折痕损坏的情况下,通过相反的外力进一步支撑钣金件的折痕位置,实现折痕损坏与凹凸损坏的转化,然后采用相应的网孔机收缩火修复方法进行修复汽车钣金件。
