Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a point-acting automatic strain relief device for thin plate structures, and the details include, for example, an outer plate,
This invention relates to a device for removing distortions in the outer panels that occur due to nine factors when assembling roof panels, floor panels, etc. (hereinafter referred to as outer panels).

Conventionally, the strain 1!# has been generally achieved by heating the member to be strain-removed, that is, the outer panel, in spots with a gas flame, and then cooling it with water, a so-called moxibustion process. In the nuclear moxibustion work, local heating is applied to the outer plate where distortion has occurred to cause thermal expansion in the heated area.
The restraining force of the non-771 heat area around the outside of the 771 heat section generates compressive force and causes plastic deformation, and after cooling, the surrounding area undergoes plastic deformation.Continuous moxibustion work causes the greenhouse of the outside panel to rise over a wide area, and the outside Since the plate itself curves even more due to thermal expansion, water is used to cool the moxibustion point and improve the quality of the outer plate.
~I tried not to. At this time, a relatively large amount of water is applied to the structure 5, and a part of it enters the inside of the Totai Yushin,
Since it is difficult to completely lose more than one part of the water, improvements have been desired to encourage early formation of structural rust. In addition, in the above-mentioned moxibustion cutting work, the heating time of the outer plate, the knowledge range, and the timing of cooling depend on the intuition and skill of the worker, making it difficult to rationalize the strain relief work.

The present invention was developed in view of the above points. Compared to gas flames, it is easier to control ignition, extinguishing, and heat input, making it easier to automate, as well as heating without unnecessarily expanding the heating point range. Yo deer! ] @ time j
The short closing time makes it possible to speed up strain relief work, and by performing high-density point heating, the partial rope gradient between the heated part and the peripheral part of the shell can be reduced to a large degree. By preventing wide-opening attacks on the board, it is possible to achieve a highly efficient and automatic planning effect, and it also prevents the triggering of steel against @sendmono. (7) It is an object of the present invention to provide a strain relief device capable of improving working conditions.
It is.

To explain in detail with reference to Figure 1, 7 is a seat plate for pressing the outer plate B, which is formed into an oval shape, and has a O-shaped cooling water channel 8 built into its middle/0 part. There is. A cooling water outlet 9 is connected to one end of this cooling water channel 8 (the right end in Figure 4), and a cooling water outlet 10 is connected to the other end, so that the cooling water flows into the cooling water channel 8. The seat plate 7 is formed with a 9-5° angle so that the seat plate 7 is cooled by circulation.

Also, on the bottom of the seat plate 7, there is a 7 with a triangular cross section for vacuum suction.

A recess is provided in the structure 11 in orthogonal communication, and a recess is provided in +t:11.
The gate 16 is connected in the center and on the right side.

In the figure, numeral 14 is a bellows made of rubber that covers the upper surface and outer periphery II'+1 of the seat plate 7, and 15 is a bellows presser that presses the upper surface and outer periphery of the bellows 14. .

Then, as shown above, the suction pressure pad 5 was prepared.
．． Between 5 and 5, a number of torches 6 to 6 (6 torches are shown as an example in FIG.
I'm pregnant.

Next, an embodiment of each torch B will be described in detail with reference to FIG. 6. Torch 6 is a TIG arc torch, with its electrode rod 16 serving as a cathode, and its nozzle 17 made of a metal conductor serving as a positive ( A TIG arc generated between the electrode N16 and the nozzle 17 (on the other hand, an inert gas etc.

In addition, y! 6 Put the torch 6 shown in the figure into the cooling water supply port 2 provided at the tip 1ILll rt++ of the d nozzle tip.
It is possible to increase the durability of the torch 6 in order to complete the cold opening of the inner periphery of the nozzle 17 by circulating cold opening water from zero.

≧Organized coefficients and a- torches 6 to 6 as shown in
keii42 As shown in Fig.
The syllables 111 are also formed in such a manner that they are syllabled sequentially from one end side with a slight time difference between them.

Therefore, as shown in FIG. 1, when strain relief is performed using the strain relief device 1 made of VCJIB as in the above embodiment, the suction pressure pads 5, 5 are connected to the h9 body bone member P, The apparatus support frame S is positioned so that the torches 6 to 6 face the outer plate to be strained, straddling P.

Next, operate the pressing cylinder 2 and move the pressing frame 4 to the outer plate B.
By pressing the suction suppressing pad 5.5 against the outer plate B, the protrusions of the outer plate B are suppressed and the concave portions are brought into close contact with the bone members P, P and the suction press pad 5. , 5 is held in a planar state as if it were firmly attached to a rectangular frame.

Next, when a voltage is applied to the plurality of torches 6 to 6 with a slight time difference, only the portion facing each torch 6 to 6 is heated locally and for a short period of time, and the strain is removed. It will be done. At this time, the above-mentioned heating is not a point-like force with a time difference, but the outer panel is held firmly in a flat shape, so the influence of large joints on the outer panel is prevented and extremely Distortion can be removed efficiently.

As explained above, the device of the present invention maintains the outer plate between the +4 contacting bone members in a flat state and sequentially heats only the portions facing each torch in a point-like manner to hide the area, thereby achieving efficient and eye-catching performance. Distortion can be removed.

Furthermore, since there is no need to inject water into the butto board for cooling, it is possible to prevent the formation of steel on the structure to be strained, and to improve the working environment compared to the conventional method. It is something.

In addition, in the above-mentioned embodiment, the technique of arranging two suction pressure pads 5, 5 in parallel was illustrated, but the present invention is not limited to this, and six or more suction suppression pads may be arranged in parallel. It is also possible to align and attach several torches to each suction suppression pad's 1) 15 Vc collar, and in this case, strain can be removed over a wide range of areas at the same time.

Next, embodiments of the support frame when the strain relief device according to the present invention is used for strain relief of blood and blood bodies will be explained with reference to FIGS. 7 to 149. In FIG. Side window opening 7
B is the outer plate attached to the outer side of the vehicle body excluding the side chamber opening.

In the embodiment shown in the turf diagram and Figure 7A8, there is a cart W that can be moved along the outer panel of the balustrade for strain relief. Six sets of strain relief devices A, C, and C are installed so that their mounting positions can be adjusted by a slight amount in the vertical and horizontal directions. However, the strain relief device IA is installed above the side window, that is, at the high point of the curtain plate, and the IC is installed below the side window, that is, at the high point of the wainscot. formed so that point heating can be applied sequentially,
Further, from the same side, between the side windows and D, that is, in the so-called blowing part, a section is formed so that spot heating can be performed sequentially along the vertical direction.

In Figure 2ζ and Figure 9, it is formed so that the cart W can be moved while guiding the support frame SB by a guide G mounted on the building frame F.

Note that the outer panel of a vehicle generally has a curvature in the vertical direction in many cases. If you try to set this 14-position suction pressing pad in the vertical direction, you will need to prepare one that matches the curve of the vehicle.

However, since the non-inventive device f uses spot heating, even if the vehicle outer panel has a curvature in the vertical direction, it is sufficient to use a suction pressing pad in the lateral direction, so it can be flat. Therefore, it can be said that the inventive inventive device has a wide range of uses and is extremely effective as a strain relief device for military and military shell panels.
