How To Use The Car Dent Repair Tool

Car dent repair tool, is the car's exterior pits without painting and not sheet metal with special tools flat, and the original exactly the same. So what are the key points of knowledge in the use of the depression repair tool, which need to be mastered by everyone?

1, car depression repair tool depression repair size.

Large car depressions and small car dents are repairable, the center of the depression or the edge of the depression has dead or hard impact to produce a dead depression, this car depression repair will not reach 100%, this point must be noted.

2, car dent repair tool use points.

Use large not small, with thick not to be thin, first large to small, first thick and then thin, with short not long, can use short as possible short, short can not be enough to use long.

3, car dent repair tool fulcrum The fulcrum is very important, can hang the chain fulcrum as far as possible hanging chain so good force, can not hang the chain of the description gap is relatively narrow, fulcrum as far as possible to the front (hook bend to do fulcrum, do the concave hand action is to rotate the tool handle with the tool's head to lift the bottom of the depression, find a good fulcrum is equal to use good leverage. Some places have a hard time finding repairs when it's particularly laborious.

Property analysis of Qijian depression

Automobile body depression is generally the deformation of stamping metal parts on the surface of car body caused by external force.

This kind of deformation can be divided into two cases according to mechanical properties

(1) Elastic deformation:

This kind of deformation does not change the mechanical properties of the metal itself. When the external force disappears, the workpiece will recover itself.

(2) Plastic deformation:

This kind of deformation destroys the mechanical properties of the metal itself. When the external force disappears, we cannot return to the original state relying on our own ability, so we need to restore it artificially.

Obviously, the deformation of car body is generally plastic deformation, otherwise, there is no need for maintenance personnel to work.

During the maintenance, it is the key to the success of the maintenance to analyze the depression cases and grasp the focus of the depression and the size and direction of the force. And the different degree of sag, maintenance program is also different.
