Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a technique for repairing a dent in an automobile body.
[0002]
[Prior art]
In the repair of car body dents, if the degree of damage is light, the suction cup is pressed against the dent and pulled out.For heavy parts, the rod is point welded to the dent and the rod is pulled. I tried to put the dent back.
[0003]
[Problems to be solved by the invention]
In the above prior art, when the minor damage can pull out pressing the suction cup, and the remaining trace because when severe damage point welding rod, grinding Therefore point welds, coating of Pate It was necessary to finish and polish.
[0004]
Therefore, as can be seen from the above description, if the dent can be restored without requiring point welding of the rod even in the case of severe damage, the cost of repair can be greatly reduced.
[0005]
Above view the present invention, without requiring skill, without scratch the body, based on the return of the recessed portion without points welding rod even when severe damage, grinding point welding marks, fill Pate It is an object of the present invention to reduce the cost of repair by omitting the grinding and polishing work.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, the present invention forms a dam by surrounding a portion to be repaired with a viscoelastic resin composition, and forms a space by pressing a flat plate through which the inside can be seen from above the dam. The body is evacuated to repair the dents in the body, and if necessary, the space is evacuated and impact vibration is applied to the flat plate .
[0007]
According to the present invention is configured as described above, along the periphery of the portion recessed to be repaired with viscoelastic resin composition to form a dam, a space sealed by close contact flat through the weir, altitude The vacuum state can be made, and the dent is effectively restored by the synergistic effect of the suction force and the impact vibration, and the subsequent finishing work is reduced.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. A weir 4 is formed around a dent 2 formed in the body 1 by a viscoelastic resin composition 3 such as rubber clay or putty, and a flat plate 5 having high strength such as an acrylic plate or a polycarbonate plate , which can be seen through the inside, is formed thereon. Cover.
[0009]
A suction tube 6 is led out to the flat plate 5, and this suction tube 6 is connected to a vacuum pump (not shown) by a thick rubber tube (not shown). If necessary , a high-frequency vibrator 7 is placed on the flat plate 5 at an arbitrary position. It can be set.
[0010]
When the operation of the vacuum pump is started as described above, the space 8 formed by the weir 4 and the flat plate 5 is evacuated and the dent is sucked and restored, but the high-frequency vibrator 7 set at an arbitrary position on the flat plate. The vibration is transmitted to the damaged body due to the above, and the dent is effectively restored in combination with the suction force.
[0011]
In the above embodiment, shocked vibration by flat high-frequency oscillator can be accelerated as a simple means, even dent restore it to make tapping suction Shinano husk lightweight hammer vacuum pump.
[0012]
The viscoelastic resin composition is appropriately selected and used from known rubber clay or putty.
[0013]
【The invention's effect】
According as the description the invention above, the indentations of the car body caused by collision, without requiring skill, without scratch the body, will be able to recover without Rukoto that Sessu point solvent rods, It is possible to reduce the repair cost significantly by reducing the putting and polishing work of the putty.
