Function and importance
As a pillar industry in China, the automobile industry is developing with each passing day and has penetrated into all fields of social life. With the development of automobile technology and the wide use of new materials, there is a huge gap between modern cars and traditional cars, which also brings new problems to the collision maintenance of modern cars. Since 1940, the car without beam structure appeared, in order to meet the needs of economic and environmental protection in the automobile industry, the weight of the car body steel plate is getting lighter and thinner, and the alloy composition of the material is getting more and more complicated.
Automotive sheet metal maintenance is the work of repairing the large and small damages caused by automobile collision, that is, automobile body repair. It is different from the traditional blacksmith and cold-working sheet metal worker and plays an important role in the whole automobile maintenance process. The repair degree of car body collision damage will directly affect the service performance and safety structure of the car after repair. Generally, after a car accident, the damaged parts are damaged to varying degrees, and the structure and theoretical parameters of the car body will always change to varying degrees. The changes of these injuries have caused different degrees of damage to the hit vehicles, and the repair of these injuries is the specific work for our maintenance workers in automotive sheet metal.
If the car body collision damage is not repaired in place, then all the equipment connected to the car body, including the engine and gearbox, will not work normally. For example, if the position of the front and rear axles connected with the cross beam of the car body is not repaired by stretching, the front and rear axles will not be connected normally, so that the engine, gearbox, steering system, braking system, etc. will not work due to the change of position, resulting in new, more and greater failures. For example, * * * vibration phenomenon, deviation phenomenon and tire gnawing phenomenon. For example, after the roof of the car body collapses in a large area, if the roof maintenance is not in place, the roof skylight will be badly damaged, which will shorten the service life and even cause water leakage and dust leakage. This is especially true for the car body. If the recovery is not in place, the body glass can't rise and fall normally, and the door is not closed properly.
Nowadays, new cars are made of high-strength rigid materials, and the body structure mostly adopts "3H" structure. If the "3H" structure cannot be effectively repaired, it will bring greater security risks to the repaired vehicle. Body safety is active safety, while driving, it is passive safety for drivers and passengers to wear seat belts. First of all, under the condition of ensuring the safety of the car body, the seat belt worn by the driver and the airbag installed on the car can work effectively, and effective safety protection can be ensured in the event of an unfortunate collision.
Automobile maintenance workers are now roughly divided into: automobile maintenance mechanics and electricians, providing various maintenance work for vehicle engines, gearboxes and body electrical systems. Automobile maintenance sheet metal workers provide effective and reliable repair work for body collision damage. Car maintenance painters provide paint treatment work inside and outside the car body. The work of automobile maintenance sheet metal workers has been widely concerned by automobile maintenance industry management departments, automobile maintenance enterprises and the majority of car owners. Paying attention to body repair is actually a concrete manifestation of cherishing life and traveling safely.
Automobile maintenance sheet metal workers have high technical content and strong technical requirements. At present, almost all automobile maintenance enterprises at home and abroad are training the front-line sheet metal workers in theory and practice irregularly, so as to enrich their technical connotation, make them familiar with the latest repair technology of modern new automobile body structure, body materials and body collision damage, and skillfully use various sheet metal equipment and tools at home and abroad. Body maintenance skills are constantly updated, and the majority of sheet metal maintenance personnel are also learning and training in various ways. Similar articles on body maintenance in various auto repair magazines are endless, with famous sayings and experts.
