The basic pulling task of the truck frame machine for body correction is to restore the damaged body to its original shape, in addition to restoring the metal to the lattice state of the crude oil. It is usually possible to level and straighten a trolley car through a series of one-way pulls. But for monolithic bodies, multiple pulls are required to work, meaning that four or more pull points can be pulled simultaneously during a single leveling and correction. Professional clamps must be provided to prevent further damage to the body structure during the drawing process and reasonable correction procedures must be followed. Let's take a closer look at the relevant considerations.
Here is the content list:
l Before and after traction correction
l Drawing process
l Complete calibration equipment
When using the truck frame machine, pay full attention to safety precautions. Otherwise, the calibration may fail or damage the calibration equipment. Internal components, such as seats, gauges, MATS, etc. should be protected inside and outside the body before tractive correction. Remove the outside parts of the body and use a cotton cloth or protect the body to prevent chafing. If the paint surface is frayed, it must be repaired to prevent rust. The final inspection shall be carried out in time after the completion of body correction and repair with the auto girder corrector. The inspection shall be carried out in two situations: In the case of repair without the use of fixed devices, the final measurement inspection should be made, and the body and frame size manual should be compared to determine whether the requirements of body correction are met. In the case of repair on fixed devices, measurement is not necessary, and only the matching of body control points and fixed devices can be judged.
Before stretching operation, check whether the chain and pull ring of the truck frame machine are complete and whether there is any damage, crack or damage before use. Tighten the bolts when stretching the tower column. The height of the guide ring should not exceed the warning red line. Check the chain and locking mechanism. The chain cannot be twisted. The chain should be online and the guide hand wheel should be unscrewed. When the tension is relatively large, the vehicle should be fixed on the platform, in the opposite direction of the tension with a chain fixed.
After the use of the frame machine, the site should be cleaned in time. Sheet metal tools, measuring tools, and clamps should be wiped clean and put away. Do not open the maintenance by yourself, so as not to damage it irreparably, and do not adjust the oil pump overflow valve without authorization.
