How to use the beam corrector to adjust the car body

Answer:

Body correction refers to a certain external force will be damaged by the accident or damage to the damaged parts of the vehicle to the factory when the technical standard "state" process. For the word "state", it contains two meanings. "Shape" refers to the more intuitive appearance and shape, and "state" is a more abstract deeper concept, such as whether the internal molecular structure of the metal can be arranged in accordance with the original position, the internal stress is completely released, etc. , It will be directly related to the vehicle after the repair function and life. Structural parts refers to the body to play the main support and bearing the role of the components, is the body parts of the installation base, common in the stringers, beams, post and under the beam and other parts. Such components usually have a very high strength, combined with the structure of the closed box-shaped cross-section, so the repair should take certain means and measures, the use of reasonable technology to repair.
Of course, for non-bearing body structure can often use this method of repair in place. Non-loadable body that is the traditional beam type body, and its frame is a separate component, generally thick material, is "U" steel or two "U" steel reverse welding and the formation of box-shaped components, Very high strength. Usually can be divided into frame type frame and trapezoidal frame and other types, through the bolt and body together. Such a frame in the impact of deformation, the usual repair method is to remove the cab and cargo compartment and then a separate frame to correct. In fact, such a frame even after the removal of the above components is also difficult to have a good anchoring method, so for some damage types of deformation can be used in Figure 2a in place repair. When the frame is bent laterally, an I-beam (rail steel) of sufficient strength can be placed on the side of the vehicle, using a horse stool or wood to fit it to the frame level, The I-beam and the front and rear parts of the frame fixed, bending parts of the top of the hydraulic pressure applied to the method of correction.
When the overall body is calibrated, the method of repairs should be made as far as possible. This can be effectively in the stretch around some of the deformation of the way "with" out, but also because of the small number of components and save a lot of time. Figure 1a is a damaged front bar skeleton, which is a closed box-shaped cross-section member which is connected to the front stringer by means of screws. Under normal circumstances, a lot of sheet metal maintenance technicians will be removed after the skeleton correction, this is actually unscientific. After the front bar skeleton in the impact, the impact force will cause the transmission of the longitudinal beam deformation. Skeleton removed after the appropriate fixation is difficult to take a gentle correction force to repair, and repair the skeleton after the need to repair the front stringer. So it is better to repair it in place by using a puller to apply a gentle force against the deformation in the opposite direction to the deformation, and then use a suitable pry bar to extend from the opening of the edge to the side of the skeleton Recessed parts of the dressing, this will get a very good effect.
