Abstract

PURPOSE:To surely join a plate body without accompanying the inconvenience of a dust, burr, etc., spoiling its external appearance by filling up a thermosetting resin between two plate bodies and curing the thermosetting resin by giving ultrasonic vertical vibration with pressing the plate body. CONSTITUTION:A piston 24 is driven with the actuation of an air cylinder 22, a horn 30 is pressed via an ultrasonic wave generator 26 and the folded end part 12a of an outer side metal plate body 12 is pressed. The ultrasonic wave generator 26 is actuated simultaneously with this pressurization, exciting the horn 30 in the vertical direction. The ultrasonic wave is thus propagated effectively to the thermosetting resin 14 of the hem inner part through the plate body end part 12a, the resin 14 is cured by being heated and adhered to both metal plate body end parts 10a, 12a. Consequently both metal plate body end parts 10a, 12a are strongly joined with the adhesion force of the cured resin 14 without receiving any deformation nor external wound.

に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for reliably joining plate bodies without causing defects such as dust, cracks, or dents that impair the appearance of the plate bodies.

（従来の技術） 例えば、自動車ドアは外側の金属板体と内側の金属板体
とからなり、それら２つの金属板体はドアの周縁部（ヘ

ことになる。Until now, spot welding has been widely used to join such hems, but the specific method is not the most basic and typical direct spot welding, but indirect spot welding or series spot welding. It was welding. In other words, direct spot welding is a method in which the welding point is sandwiched between a pair of welding electrodes and the welding current is passed from one electrode through the welding point to the other electrode. Electrode marks are left on the outer surface, spoiling its aesthetic appearance. Therefore, indirect or series spot welding, which can be performed by applying the electrode only to the back (inner side) of the door, is used.

第２図は、インダイレクト・スポット溶接による自動車
ドアのヘム接合方法を示す。FIG. 2 shows a method of joining an automobile door hem by indirect spot welding.

この図において、１００．１０２はそれぞれドアの内側

ヘムが形成される。In this figure, 100 and 102 are the inner and outer metal plates of the door, respectively. The end 102a of the outer metal plate 102 is bent into a U-shape so as to wrap around the end 100a of the inner metal plate 100, thereby forming the hem of the door.

れる。However, hems that are simply assembled in this way tend to come off easily, so they need to be fixed (joined). Welding electrodes 104 and 106 are connected to output terminals of a power supply circuit 108, respectively. One welding electrode 104 is connected to the outer metal plate 1
02, and the other welding electrode 108
is applied to the central portion 100b of the inner metal plate body 100.

しかして、このヘム接合では、溶接電極１０４に加圧力
Ｐを加えて両金属板体端部１００ａ、１０２ａを圧接し

抗発熱を生ぜしめ、そこを抵抗溶接する。Therefore, in this hem joining, while applying pressure P to the welding electrode 104 to press the ends 100a and 102a of the metal plates, the power supply circuit 108 connects the welding electrodes 100 and 102 to each other.
A predetermined voltage is applied between them to flow a current I as shown by the arrow to generate resistance heat generation at the joint surface between the ends 100a and 102a of both metal plates, and resistance welding is performed there.

The welding current I flowing from 04 to the welding points 102a, 100a passes through the central part 100b of the inner metal plate 100 and reaches the other welding electrode 10Ei away from the welding point.
(this is truly indirect spot welding), the current concentration at the joint surface is poor, which not only results in poor welding, but also creates dust and flakes, which worsens the appearance of the door. In addition, in order to avoid welding defects as much as possible, the pressurizing force P is increased (then, after welding, marks of the welding electrode 104 will remain clearly on the surface of the metal plate end 102a, and it will not be aesthetically pleasing even if it is inside the door). not good.

このような不具合はシリーズ・スポット溶接でも同様に

法が最近試みられている。Therefore, instead of welding, a method has recently been attempted in which the hem is joined by filling or injecting a thermosetting resin into the hem and heating and curing it during the painting process. ing.

なってヘムが外れやすいといった問題もある。However, since it would be undesirable if the inner and outer metal plates come apart after they are assembled and before the painting process, some parts of the hem should be temporarily joined using indirect spot welding or series fist spot welding as described above. There is. Therefore, although there are differences in degree, the above-mentioned problems will still occur during temporary joining, and if there are few temporary joining points or poor welding, the joint will be weak and the hem will easily come off. There are also problems.

（問題点を解決するための手段） 上記目的を達成する本発明の方法は、２つの板体の間に

The method is characterized in that the plates are joined by curing a curable resin.

伝わりをよ（する。(Function) When ultrasonic longitudinal vibration is applied to the thermosetting resin, the thermosetting resin is heated by the ultrasonic energy, hardens, and adheres to both plates. This adhesive force provides a bond between the drawing board bodies. The pressure applied to the plate increases the transmission of ultrasonic longitudinal vibrations to the thermosetting resin.

このように、本発明では、板体間の熱硬化性樹脂に作用

ものが得られる。In this way, in the present invention, since the thermosetting resin between the plates is used to join the plates, there are no defects such as dust, cracks, or dents that spoil the appearance of the plates (and the bonding force is sufficiently strong). You can get something.

（実施例） 以下、第１図を参照して本発明の一実施例による自動車

持台で、装置２０からの加圧を受けとめるものである。Reference numeral 20 denotes a pressure/ultrasonic longitudinal vibration device for carrying out the hem joining of this embodiment. An air cylinder 22 as pressurization generating means is housed inside the main body of the device 20, and its piston 24 is connected to the upper surface of an ultrasonic generator 26. This ultrasonic generator 26 is slidable along the roller guide 28 and generates ultrasonic waves that vibrate in the sliding direction. The lower surface of the ultrasonic generator 26 is connected to the horn 3
0, and the tip (lower end) 30a of the horn 30 is placed against the folded end 12a of the outer metal plate 12. Reference numeral 40 denotes a support base that receives pressurization from the device 20.

The folded end portion 12a of is pressurized. Simultaneously with this pressurization, the ultrasonic generator 26 operates to excite the horn 30 in the vertical direction (in the direction of arrow FO).

リ、パリなどは発生しない。As a result, the ultrasonic waves are effectively transmitted to the thermosetting resin 14 inside the hem through the plate end 12a, and the resin 14 is heated and hardened by the ultrasonic energy, and is bonded to both metal plate ends g10a and 12a. do. At this time, the tip 30a of the horn 30 comes into strong (pressure) contact with the surface of the folded end 12a of the outer metal plate 12 due to the pressurization and ultrasonic longitudinal vibration, but it is not so strong as to create a depression on the surface. In this way, the ends 10a and 12a of both metal plates are strongly joined to each other by the adhesive force of the hardened resin 14 without being particularly deformed or damaged.Furthermore, when electric current is applied to the metal plates as in spot welding, Since it is not flushed away, naturally there will be no dust or debris.

よい。- As an example, for the thermosetting resin 14 with a curing temperature of about 150°, apply a pressure of 60 kg and an ultrasonic frequency of 15 k.
You can choose Hz. The pressure is to increase the efficiency of the energy of the ultrasonic longitudinal vibration transmitted to the thermosetting resin III 14, but if it is too large, there is a risk that marks from the horn end 30a will be left on the surface of the metal plate end 12a. It is best to choose an appropriate value like the one above. In addition, the higher the ultrasonic frequency, the greater the energy given to the thermosetting resin 14, but if the ultrasonic frequency is too high, the horn must be made proportionally smaller, which leads to problems in terms of horn strength, pressing force, etc. There is a problem, so it is better to choose an appropriate value like the one above.

This problem can be solved by applying pressure and ultrasonic longitudinal vibration from the direction of arrow F1.

。After joining the hem as described above,
The horn 30 is moved a little and the same joining as above is performed at another location. By reducing this moving interval, almost perfect hem bonding can be achieved by the method of this embodiment before heating in the coating process. However, it is also possible to increase the movement interval and perform temporary bonding by limiting the bonding according to this example to a few locations. In that case, the remaining (uncured) thermosetting resin is cured by heat treatment during the coating process, and the final bonding is performed. It turns out.
