【正文】 ar fender, luggage partment, rear lamp, glass, wheels, etc.。 if the collision point of the car side, the site should be checked at least include: doors, roof, glass, columns, floor plate and other parts and suspension. The second part: the collision point is outside than in other parts of the injury。 therefore, it may involve a larger scope. Check indirect injury, should check the size of the collision force, direction, absorb impact force ponent strength。 observe signs of surface ponents, any body sheet metal ponents by the collision between material will have small cracks, such as bodywork was roof damage convexshaped, body ponents should be in addition to checking one corner of the yield ponents of metal materials and so on. The third part: The main damage is to check the car parts, check whether the engine and transmission damage the assembly. The fourth place: the main is to check the passenger partment internal attachment injury, opened the carpet and the surrounding insulation material, observe the surface of metal ponents, checking seat installed, seat belt anchors, instrument panel and other signs of injury。 also Turn steering wheel to wheel in a straight line driving position, check whether the steering wheel in the middle position, with or without free itineraries. Fifth position: check the body shape is matched ponents, decorative lines are aligned and the coating status. Do not think that is unimportant, a waste of time, body collision correction, collision damage check is the key body correction process. Auto body repair correction, there is a basic principle, and by the collision force in the opposite direction with corrections, in the collision region Shijia La force to be corrected. Auto body damage when the collision damage is very small, when the collision damage is relatively simple, this method is very effective, and now all kinds of body repair shop is equipped with a body sheet metal repair machines, such repair operation is simple. Auto fit the injury causes plex body structure and ponents as the reasons for forming, in particular body ponents using thinwalled box structure of the force of the collision and repair it difficult, such a simple mode of operation with stretching on body can not make restitution. For example, the body panels subjected to impact, it has bee a plex shape。 the same time, its intensity has changed, if only in the opposite direction Shijia La Force, it is impossible to restore its original shape, because each ponent of the strength of body and correction recovery is not exactly the same, the same body shape ponents produced by different impact of different collision damage。 for example, body fender parts in the bending radius of less intensity, by the collision damage deformation will be smaller, the more flat fenders part deformation will look great, in fact, very little by the collision and impact, ponent damage more positive, as long as the fender bending radius not smaller plastic correction, flattened part of the depression will be restored to its original shape ponents . Determine the calibration process is an integrated plex issue, often need to repair personnel in various aspects of knowledge, such as body structure, the mechanical properties of metallic materials, proper use of such equipment. Here the deposition process first tensile strength were analyzed and introduced. Body Crash correction correction itself should be prepared by the body, the calibration device placed in the position need to stretch。 this time, staff will need to repair the direction of the tensile force perpendicular to the ponent parts of the location of injury。 time, repair personnel need to tensile direction is the direction of the end of two or more tensile strength。 this method just handed power to a point on the curve if the ponent level is too large, the stiffness of a strong, correct results are not satisfactory, or even can not Component correction back to its original shape。 can at different points Shijia La Force, according to the deformation of the ponent location settings to correct the many directions。 such as tensile strength from the above analysis, we can know, may be the only force in one direction deposed into two directions contribute, in the process of correction can also be based on degree of deformation recovery, contribute to the adjustment of tension at any time, if the correction process together with other calibration methods can wait for better results. If you stretch the triangle in the system configuration Wei incorrect state, it must immediately stop drawing, otherwise, the chain ends of the clips may have been set, resulting in equipment, chain or other damage. During operation, the connection point with the location of the body height is also a key operation, should try to force the angle between the plunger and the zipper and the plunger and the angle between the fixed points are equal, when the extension point move high position, power pole AB elongation, the chain will stretch journey. Operation in the implementation of the injection stretch child matters: 1. integral body of metal material, some as high strength materials, it is best not to try to step in to plete the plastic correction, but through a series of stretching operations, including drawing a balance once again to balance the cycle again pull Chung, such can slow the relaxation of metal materials, can pay attention to check the correct operation of progress, in particular body force ponent of the defects situations, preventing excessive bit extension。 that is, slowly, carefully and start the hydraulic system, careful observation damaged parts of the body movement, to see if corrective to the appropriate position and shape, if not, the reasons should be checked, adjust the angle and direction of restarting, reuse hammer to eliminate stress, with a hammer, so that stress release, then stretch again so that relaxation can not be determ
