Problems solved by technology

Because it is point traction, it usually needs to be carried out at multiple points. When pulling out, the traction point is more prominent than other places. When beating it, it will be repeatedly flattened, resulting in a large amount of local repeated deformation. After the thin iron plate passes through this process, it will be damaged again. The strength is greatly reduced, which affects the mechanical strength after repair
In addition, this method also has the disadvantages of many processes and troublesome operation.

Embodiment Construction

[0010] Such as figure 2 As shown, the suction cup 2 of this device is made of metal, and its center is provided with a pull ring 2-2, which can be connected during traction, and a rubber sealing ring 2-1 is provided along the mouth, which acts as a seal, and the suction cup is provided with an air outlet 2-3, for connecting the vacuum pump to extract the air inside the suction cup.

[0011] When using the connection as figure 1 As shown, the equipment used includes a vacuum pump 4, a suction cup 2, and a tractor 5. The suction cup 2 is connected to the vacuum pump 4 through a pipeline 3, and the suction cup 2 is connected to the tractor 5 through a pull ring.

[0012] When repairing, place the suction cup 2 on the concave part of the sheet metal part 1, vacuum the air in the suction cup with the vacuum pump 4, then pull the suction cup 2 through the tractor 5, pull out the concave part, and restore it by beating. The vacuum pump used is a piston type with a vacuum degree of...

Abstract

The method of repairing plate part of automobile includes setting sucking disc in the notched part, pumping out air from the sucking disc, drawing the sucking disc to draw out the notched part and knocking to restore the original shape. Compared with available repairing method, the method of the present invention has the advantages of no need of welding, less deformation and damage of the plate part and simple operation.

Description

technical field [0001] The invention relates to automobiles, in particular to the improvement of the method for repairing automobile sheet metal parts. Background technique [0002] After the collision of the car, the sheet metal parts of the shell are deformed, mainly due to concave deformation. In the case of slight deformation, the current repair method is to weld a pull ring or iron wire that can provide traction in the concave part, and then use a hoist to repair it. Pulling, pulling it out, removing the welds, heating and tempering the damaged parts, and finally restoring the shape by hand beating. Because it is point traction, it usually needs to be carried out at multiple points. When pulling out, the traction point is more prominent than other places. When beating it, it will be repeatedly flattened, resulting in a large amount of local repeated deformation. After the thin iron plate passes through this process, it will be damaged again. The strength is greatly red...
