Description

Technical Field

[0001] The invention relates to the technical field of automobile repair, and in particular to a device for repairing dents and deformations of automobile sheet metal. Background Art

[0002] The most common repair in automobile maintenance is that the outer skin of the car is dented and the paint is peeled after a collision, that is, the car sheet metal is dented and deformed. The main way to repair the dent is to pull the dented position to restore it to its original shape. During the repair, a pulling row or a welding piece is used to fix it, and the dented position is pulled by a pulling tool. Common pulling tools include hammer-type manual pulling tools. This tool has high requirements for the operator. Therefore, there are also fixed pulling tools such as brackets that do not rely on the level of the operator. For example, the Chinese invention application with the authorization announcement number CN112090991A discloses a car sheet metal dent deformation repair device, which discloses a car body, a support platform, a steam engine and a vacuum pump are arranged on the car body, and a connecting pipe penetrating the support platform is arranged on the support platform, and the steam engine is connected to the connecting pipe through the steam inlet pipe; However, this type of repair device has the following defects:

[0003] For smaller sheet metal dents and deformations, direct pulling can repair them. However, if the dent is large or has a complex shape, pulling only at the dented position will cause deformation at other locations, and a reaction force needs to be applied to the rest of the sheet metal. However, current repair devices are unable to apply a reaction force, resulting in larger dents or those with complex shapes being unable to be repaired.
