Then, step S8 is executed to determine whether the preset fourth cooling time is reached, if yes, step S9 is executed, and it is determined that the repair is completed.
Wherein the vehicle body to be repaired is cooled by using compressed air in the working area of the repair machine 40 before the repair machine 40 is brought into an operating state. Specifically, during the use, since the repair head 20 is rapidly heated during repairing the damaged vehicle body, the repair head 20 and the vehicle body do not operate for a long time in the same area, and after a certain period of time, for example, 1 to 15 seconds, the damaged part is repeatedly wiped by a wet towel, or the vehicle body to be repaired is cooled by compressed air, so that the temperature is reduced, and the damage to the vehicle paint caused by the excessive temperature is avoided. In addition, during the operation, a large amount of heat is generated during the repair, the temperature of the repair head 20 and the vehicle body can be rapidly increased, the vehicle body can be instantaneously softened slightly, and the repair head 20 is not required to be pressed down during the operation, so that the concave part is not increased due to the instantaneous softening, the humidity of the surface of the vehicle body is required to be paid attention to during the repair, and the vehicle paint is burnt and damaged due to overheating, so that larger damage is brought.
Therefore, the method for repairing the surface of the automobile by heat treatment determines the working time and the working efficiency of the repairing machine by acquiring the area size and the color of the concave area of the automobile body. In the use process, the repairing head 20 is contacted with the surface to be repaired of the automobile, the button switch 24 of the repairing head 20 is pressed, corresponding power and time are output according to the setting of the main control chip 10, the repairing head 20 is used for heating the periphery of a sunken area of the automobile body in a rotating way to repair the sunken part of the automobile body, an iron plate of the sunken part to be repaired is placed in a magnetic field by utilizing an electromagnetic principle, so that local vortex heating is generated, the sunken part on the surface of the automobile is restored by utilizing the principle of thermal expansion and cold contraction, and the sunken part of the automobile body is repaired.
It should be noted that the foregoing is only a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made to the present invention by using the concept fall within the scope of the present invention.
