According to the research and analysis of the current auto parts market in my country, most parts suppliers are unable to ensure the quality of parts, and most of the auto parts have not been tested for quality and are sold through improper channels. This behavior has had a serious impact on the normal operation of the auto parts market, reducing the quality and safety of the parts in the entire market. This requires that relevant departments should strengthen the supervision of the auto parts market, and promptly investigate and deal with inferior products circulating in the market, so as to effectively ensure the overall quality of auto parts. In addition, consumers must purchase auto parts through formal channels, and do not choose low-quality products that are too low.
When the car is squeezed by the rib, it will cause its sheet metal parts to bend. The common reason is that the car suffers an accident and the car sheet metal parts are bent. Generally, the impacted parts are severely bent and deformed, and the surrounding sheet metal parts will have much less impact.
When confirming the camber caused by the impact, professional testing tools can be used to measure it. In addition, the bending degree of the peripheral position of the sheet metal part can be observed to predict the damage degree of the sheet metal part. If the frame of the car body is bent to different degrees, it needs to be repaired by the support method. At this time, pay attention to the force generated in the deformation direction, which needs to be opposite to the force in the support direction.
When the sheet metal parts of the automobile body are hit by the rib, they may be torn and damaged. When repairing lightly damaged sheet metal parts, first straighten out the tear position, and then perform welding repair fabrication. If the sheet metal part is seriously damaged, it is necessary to observe the shape of the tear first, and choose to repair or replace the new sheet metal part according to the actual situation.
When the repair conditions are ideal, C02 gas can be used to perform protective welding repair on the sheet metal parts, and observe and detect whether there is an outstanding ductility problem at the damaged position of the sheet metal parts. If the test results are consistent with ductile outstanding damage, it needs to be repaired by professional repair methods.
