What to do with the deformation of the front beam of the car

In addition, after repairing the skeleton, the front longitudinal beam needs to be repaired. Therefore, the correct way is to carry out on-site maintenance. Use the stretching tool to apply a relief force opposite to the collision direction to the deformation part, and then use an appropriate pry stick to enter from the edge opening and correct the concave part of the lateral edge of the skeleton, which can achieve very good results.

Therefore, a better way is to carry out in-place repair, use a pull to apply a gentle force opposite to the direction of impact to the deformation part, and then use a suitable pry stick to stretch in from the opening of the edge to trim some concave parts on the side of the skeleton, which will achieve very good results.

The deformation repair of the front beam of the car generally takes about 5 days: the correction method of the car beam: the preparation of the equipment. First of all, we need to prepare the equipment used to correct the beam.

The beam correction method requires the preparation of equipment, including beam correction devices, fixtures, hammers and tools. Before use, it is necessary to check whether the beam correction device is clean and there is no garbage, and then extend the damaged vehicle to the beam correction device.

Introduction to automobile body deformation repair method

1. Repair method of automobile sheet metal depression deformation: hammering method, attraction method and manual traction method. Hammering method Hammering method is a common treatment method to repair uneven deformation.

2. For general slight deformation, it is mainly used to cut, disassemble and disassemble the deformed parts and components. After correcting the lower part, it is welded or installed in the original position.

3. The repair of body impact damage is mainly accidental trauma repair. Common methods include shrinkage and shaping, fold unfolding, stretching and pad pry reset, etc. Shrinkage forming In order to restore the deformed parts to their original shape, it is necessary to find a way to shrink and extend the parts.

4. The essentials of opening the folds, first of all, try to pry open the dead fold from the inside, relieve it into a living fold, then heat it up, knock on the most convex ridge of the live fold with a hammer, gradually expand it, and restore it to its original shape. 2 In pairs of local collisions, the damage to the driving room does not affect the skeleton deformation, and most of them can be corrected by knocking.

5. The repair of the car body is mainly accidental trauma repair. The methods usually used are contraction shaping, fold unfolding, support and pulling and pad pry reset, etc. When resetting the support and pulling, the damage of the vehicle should be carefully observed first and the necessary tests should be carried out.The diagonal measurement method can be used to detect the deformation of the car body, cab and engine room, etc.

What to do if the car rack is deformed

1. The general basic method is to remove the whole car and shape it or replace the corresponding parts before re-riveting. For serious frame deformation, the frame assembly should be replaced as soon as possible to completely eliminate this hidden danger; as for the broken frame failure, it is easy to find during regular inspection of the car.

2. Due to the inevitable "elastic" and "aftereffect" effects in pressure processing, the deformation value of correction should be greater than the actual needs, and a certain force time should be maintained. After the frame is corrected, it should meet the overhaul inspection standards, and the rivets on the frame should be checked to eliminate the loosening that may be caused during the correction process.

3. Leave some space to reverse the car and pull it out until it is in place. Be careful not to pull out too much. The above method is a stupid way to save money, but it is very practical. The one who makes sheet metal may have used it, (on Pusan) and the upper beam corrector, you can pull as much as you want.

4. After the sub-frame is deformed, everyone should replace it immediately. The front and rear of the car have a sub-frame. The front sub-frame also needs to support the engine and gearbox, and the front sub-frame is also responsible for transmitting the impact force to the entire body in case of a collision. The sub-frame with good energy absorption effect is a full-frame sub-frame.

5. Able to repair. Tie the front axle with a rope, tie the other end to the telephone pole, and then pull the car back a few times, and it will recover.

6. ItsAfter replacing new accessories or repairing, in order to avoid deformation again, you can consider strengthening the support points, for example, installing the upgraded support points or adding support points. Finally, the deformation of the car support point needs to be dealt with in time, because it will have a negative impact on the stability, driving safety and life of the car.

Measurement of how to handle body deformation of automobile body deformation

1. Measurement of overall deformation of automobile body: Body shaping positioning detection is to use the measurement system provided by the straightening system to measure each measurement of the body Measure the coordinate parameters of the point, and compare the measurement data with the standard data of the model to check the straightening quality.

2. It can also be combined with test drive and measuring instrumentThe device conducts a comprehensive inspection of the car to confirm whether the bottom of the car is deformed, whether the whole body is damaged and distorted, whether the door opens freely, etc. So as to determine the degree of damage and repair method of the car. [ Body replacement] When the car is seriously damaged, you can consider replacing the entire car body.

3. For general slight deformation, it is mainly used to cut, disassemble, etc. of the deformed parts and components. After correction in the lower part, it is welded or installed in the original position.

4. Measurement of size: In the body structure, most control points are holes, and the measurement of size is to measure the center point to the center point. Generally, a track gauge is used for measurement.

How to repair the deformation of the bottom of the car

If the dents on the bottom of the car are not serious, you can use sheet metal to restore the car to its original shape.When using sheet metal, various tools can be used to restore the prototype of the car. If the dent is very serious, you need to replace the bottom of the car directly, and you can't use sheet metal. Car dent repair is to repair the dented part of the car paint to its original state.

If the dent of the bottom of the car is not very serious, sheet metal can be used to restore the original shape of the car. When sheet metal, various processes are used to restore the prototype of the car. If the dent is very serious, the bottom edge of the car needs to be directly replaced, and sheet metal cannot be used.

Among them, plastic materials are relatively easy to repair. Because plastic products have good elasticity, you can try to pour some boiling water on the concave to make it bulge. If it is not good, you can also pull it out with some professional pulling tools.
