【考案の詳細な説明】
この考案はワークにファスナを加熱して接着する改良さ
れた誘導加熱装置に関する。[Detailed Description of the Invention] This invention relates to an improved induction heating device for heating and bonding a fastener to a workpiece.
従来の誘導加熱装置のＵ字形を鉄心の脚の下端面は脚の
長子方向に対してはＳ゛直交ているので、接着して固定
すべきファスナのスタッドの軸方向長さが鉄心の脚より
も長いと、脚の上端間を連結している連結部がスタッド
に邪魔され、鉄心はファスナを跨ぐことができないので
ファスナを加熱して接着することができない。The lower end surface of the leg of the core of a conventional induction heating device has a U-shape, and the lower end surface of the leg of the core is perpendicular to the longitudinal direction of the leg. If it is too long, the stud will interfere with the connection between the upper ends of the legs, and the iron core will not be able to straddle the fastener, making it impossible to heat and bond the fastener.
この場合は脚の長さがスタッドよりも長い別の鉄心を使
用する以外に方法はないが、そうすると脚が長い分、鉄
心の熱損失は大きくなり加熱効率が減少すると言う欠点
がある。In this case, the only option is to use another core with longer legs than the stud, but this has the disadvantage that the longer legs cause greater heat loss from the core, reducing heating efficiency.
そこで本考案は鉄心の脚の下端面を脚の長子方向に対し
て鋭角に傾け、これにより鉄心の脚の下端面をファスナ
に上から当接すると連結部はファスナのスタッドからそ
れる様にし、スタッドの長さが鉄心の脚より短かい場合
は勿論、長い場合でもファスナのスタッドの直下の接着
剤を集中的に加熱して溶かし、ワークにファスナを接着
、固定できる様にしたのである。Therefore, in the present invention, the lower end surface of the leg of the iron core is tilted at an acute angle with respect to the longitudinal direction of the leg, so that when the lower end surface of the leg of the iron core comes into contact with the fastener from above, the connecting part deviates from the stud of the fastener. Even when the length of the stud is shorter than the leg of the iron core, or even when it is longer, the adhesive directly under the stud of the fastener is melted by intensive heating, making it possible to bond and fix the fastener to the workpiece.
従って、本考案によれば鉄心の脚よりも長いスタッドを
有するファスナであっても、鉄心は熱損失を生ずること
なく効率的にファスナを加熱し、ワークに接着、固定す
ることができる。Therefore, according to the present invention, even if the fastener has a stud that is longer than the legs of the iron core, the iron core can efficiently heat the fastener and bond and fix it to the workpiece without causing heat loss.
更に脚の下端面の面積は脚の断面積よりも広いので、そ
の点でもファスナのベースに広い面積で接触し、ベース
の加熱を効率的に行える。Further, since the area of the lower end surface of the leg is larger than the cross-sectional area of the leg, the lower end surface of the leg comes into contact with the base of the fastener over a wide area, and the base can be heated efficiently.
以下、本考案を図示の実施例を参照して説明する。Hereinafter, the present invention will be explained with reference to the illustrated embodiments.
１０は本考案のＵ字形をした鉄心の一例を示し、これは
１対の脚１４を有し、両脚１４は上端間を連結する連結
部１２に対し直角になっている。Reference numeral 10 shows an example of the U-shaped core of the present invention, which has a pair of legs 14, which are perpendicular to the connecting part 12 connecting the upper ends.
そして第２図に示したように、両脚１４の下端面１６は
脚の長手方向に対して鋭角をなしている。As shown in FIG. 2, the lower end surfaces 16 of both legs 14 form an acute angle with respect to the longitudinal direction of the legs.
第１〜３図は鉄心１０がファスナー２０のベース２４を
ワーク２８上で加熱している状態を示す。1 to 3 show a state in which the iron core 10 is heating the base 24 of the fastener 20 on the workpiece 28.
ファスナー２０のベース２４は平らな上面と下面を有し
、その形状は図示の如く方形であってもよい。The base 24 of the fastener 20 has flat upper and lower surfaces and may be rectangular in shape as shown.
スタッド２２はベース２４から垂直に起立し、ベース２
４の下面には熱で活性化される接着層２６がある。The stud 22 stands vertically from the base 24 and
On the underside of 4 is a heat activated adhesive layer 26.
接着層は適当に加熱されるとベース部２４とワーク２８
を結合する。When the adhesive layer is heated appropriately, the base portion 24 and the workpiece 28 are bonded together.
combine.
ワークに固定されたファスナは、ワークに孔を明けるな
どの加工なしにワークに他のものを取付ける手段となる
。A fastener fixed to a workpiece provides a means for attaching other items to the workpiece without drilling or other processing in the workpiece.
尚、ファスナは図示のものに限らず、他の種々なもので
よい。Note that the fastener is not limited to the one shown in the drawings, and may be of various other types.
そしてそのスタッド２２はファスナのベースに物理的に
取付けたものでもよく、又、その長さは任意でよい。The stud 22 may be physically attached to the base of the fastener and may be of any length.
鉄心１０はベースの直下で、スタッド２２をほぼ横断す
る部分にある接着剤を加熱する様にする。The iron core 10 is arranged to heat the adhesive located directly below the base and approximately across the stud 22.
第１，２図で明らかなように、脚に対し斜めである脚の
下端面１６は鉄心の脚をベース上でスタッド２２の両側
に配置することを許容し、且つ連結部１２をスタッドの
側方にそらせるので、スタッドの長さが脚よりも長くて
も連結部１２はスタッド２２と干渉しない。As can be seen in Figures 1 and 2, the lower end surface 16 of the leg, which is oblique to the leg, allows the legs of the core to be placed on the base on either side of the stud 22, and also allows the connecting portion 12 to be placed on the side of the stud. Since the connecting part 12 is deflected in the opposite direction, the connecting part 12 does not interfere with the stud 22 even if the length of the stud is longer than the leg.
そして、連結部のまわりに巻回されたコイル１８により
鉄心に誘導される磁路がファスナのベース中をスタッド
の中心線を横断して形成される。A magnetic path is then induced into the core by the coil 18 wound around the coupling portion and is formed through the base of the fastener and across the centerline of the stud.
この結果、接着剤は加熱されスタッド直下で最も効果的
に硬化する。As a result, the adhesive heats up and cures most effectively directly beneath the stud.
Ｕ字形鉄心を使用し、両脚の間で磁路を形成して加熱す
る場合、ワークから最大に熱を発散させ、鉄心自体は帯
熱しない様にすることが重要で、そのためには両脚１４
の長さは所定にすべきである。When using a U-shaped core and heating by forming a magnetic path between the legs, it is important to maximize the heat dissipation from the workpiece and prevent the core itself from becoming heated.
The length of should be predetermined.
又、脚の下端面はベースひいてはワークと密に物理的に
接触させ、磁束の漏洩を防止することも重要である。It is also important to bring the lower end surfaces of the legs into close physical contact with the base and eventually the workpiece to prevent leakage of magnetic flux.
本考案によれば鉄心の脚の長さを所定にし、それよりも
スタッドが長いファスナのベースをヒステリシス損と渦
電流とによって効率的に加熱できる。According to the present invention, by setting the leg length of the iron core to a predetermined value, the base of a fastener whose stud is longer than the leg length can be efficiently heated by hysteresis loss and eddy current.
更に、脚の下端面の面積は脚の断面積よりも広いので、
脚の断面積と同面積の下端面をファスナのベースに接触
させて加熱スるよりもベースの加熱効率は大である。Furthermore, since the area of the lower end surface of the leg is wider than the cross-sectional area of the leg,
The heating efficiency of the base is greater than heating the base of the fastener by bringing the lower end surface, which has the same area as the cross-sectional area of the leg, into contact with the base of the fastener.
脚の下端面１６は脚の長手方向と直角をなす面に対し約
３０°にするのが第２図にみられるように脚をベースに
対し６０°の角度で位置決めし、鉄心の連結部をスタッ
ドの側方にそらせる。As shown in Fig. 2, the lower end surface 16 of the leg is at an angle of approximately 30° to a plane perpendicular to the longitudinal direction of the leg.The leg is positioned at an angle of 60° to the base, and the connecting portion of the iron core is Deflect to the side of the stud.
熱損失が鉄心よりむしろワークに主に生じることを確実
にするには、鉄心を積層構造にするのが好ましい。To ensure that heat loss occurs primarily in the workpiece rather than in the core, it is preferred that the core be of laminated construction.
第４，５図は本考案の鉄心を製造する好ましい方法を示
すもので、鉄心構成用の適当なシート材料３４を心金３
２の回りに四角く渦状に巻回して積層母体３０を作る。Figures 4 and 5 illustrate a preferred method of manufacturing the core of the present invention, in which a suitable sheet material 34 for core construction is inserted into the mandrel 34.
The laminated base body 30 is made by winding the base layer 2 in a rectangular spiral shape.
積層の厚さは脚１４に必要な厚さであって、これは心金
の回りに巻付けるシート材料の厚さと巻数によって定ま
る。The thickness of the laminate is the thickness required for the legs 14 and is determined by the thickness and number of turns of sheet material wrapped around the mandrel.
そして、この母体３０を脚の長手方向と直角をなす面に
対し３０°の角度の切断線３６に沿って切断し、同じ二
つの鉄心にする。Then, this base body 30 is cut along a cutting line 36 at an angle of 30° to a plane perpendicular to the longitudinal direction of the legs to form two identical cores.
以上、本考案を特定の実施例について説明したが考案は
