Description

発明の詳細な説明Detailed Description of the Invention

本発明は、薄板金属製スイッチ端子等の電気・電子部品や精密機械部品等の取り付けに好適とされる、板状部品用係止部の成形方法と、この方法に拠る板状部品の係止構造と、この係止構造を備える板状部品の取付構造に関する。  The present invention relates to a method for forming a locking part for a plate-like component, which is suitable for mounting electrical / electronic parts such as thin metal switch terminals, precision machine parts, and the like, and locking of the plate-like parts based on this method. The present invention relates to a structure and a mounting structure for a plate-like component having this locking structure.

従来技術Conventional technology

電気部品や電子部品の組付け工程において、電気部品や電子部品の１種である薄板金属製スイッチ端子等の板状部品を金属板に取り付ける方法に、例えば、図９（ａ）に示すように、金属板１にプレス加工して設けた凸部２，３，４の間に板状部品１０の基部１１を挟入させ、前記プレス加工により設けたダボ７を、板状部品１０の基部１１に開設したダボ孔１３内に突入させ、この突入後、ダボ７を上方からカシメて板状部品１０を金属板１に固定する方法がある。  For example, as shown in FIG. 9A, a method of attaching a plate-like component such as a thin metal switch terminal, which is a kind of electric component or electronic component, to a metal plate in the assembly process of the electric component or electronic component. The base 11 of the plate-like component 10 is inserted between the convex portions 2, 3, 4 provided by pressing the metal plate 1, and the dowel 7 provided by the pressing is used as the base 11 of the plate-like component 10. There is a method of fixing the plate-like component 10 to the metal plate 1 by staking the dowel 7 from above after rushing into the dowel hole 13 established in the above.

この一連の組付け工程では、図９（ｂ）に示すように部品１０の端部を指先で持って行なう。とくに、カシメ作業では、凸部２，３，４の間に板状部品１０の基部１１を挟持させた状態では、重心が基部１１から離れた個所にある板状部品１０の場合、板状部品１０の姿勢が不安定で傾き易いため、カシメ作業を終えるまで板状部品１０の端部を指先で持ち続ける必要がある。  In this series of assembly steps, as shown in FIG. 9B, the end of the component 10 is held with the fingertip. In particular, in the caulking operation, in the state where the base 11 of the plate-like component 10 is sandwiched between the convex portions 2, 3, 4, the plate-like component 10 has a center of gravity located away from the base 11. Since the posture 10 is unstable and easily tilted, it is necessary to hold the end of the plate-like component 10 with the fingertip until the crimping operation is completed.

また、従来では、プレス加工により、各凸部２，３，４の側面を板面に対して垂直に立設させていた。図９（ｃ）は、その１つの凸部（凸段部）４を正面断面形状で示し、４は凸部の側面を指している。  Conventionally, the side surfaces of the convex portions 2, 3, and 4 are erected perpendicularly to the plate surface by press working. FIG. 9C shows the one convex portion (convex step portion) 4 in a front sectional shape, and 4 indicates a side surface of the convex portion.

カシメを必要としないで板状部品を金属板に取り付ける方法では、例えば、特許文献１に記載のように切り起こした部分の内側に板材を係合させる技術、特許文献２に記載のように接合用ダボをダボ孔内に突入させて係止させる技術等が公知である。  In the method of attaching a plate-like component to a metal plate without the need for caulking, for example, a technique for engaging a plate material inside a cut and raised portion as described in Patent Document 1, joining as described in Patent Document 2 The technique etc. which make a dowel dowel enter into a dowel hole and latch are known.

発明が解決しようとする課題Problems to be solved by the invention

しかしながら、図１１（ｂ）に示すような小さな板状部品１０を指先で摘み持ちながらカシメる作業は、指先がカシメ用のパンチ６４に触れて指先の事故を起こす可能性がある。
特許文献１に記載の切り起こし部の内側に板材を接合させる構造は、スイッチ端子等の薄板金属製の小片よりなる板状部品の接合に適した小さな切り起こしを高精度で設けることが容易でない。また、金属板に切り起こしのための開口を設けることを望まない場合等もある。特許文献２に記載の接合用ダボをダボ孔内に突入させて金属板を係止させる構造は、金属板の係止が外れて金属板が脱落し易い。However, as shown in FIG. 11 (b), the operation of caulking while holding the small plate-like component 10 with the fingertip may cause the fingertip to touch the caulking punch 64 and cause an accident of the fingertip.
The structure in which the plate material is joined to the inside of the cut-and-raised portion described in Patent Document 1 is not easy to provide a small cut-and-raised portion suitable for joining plate-like parts made of thin metal pieces such as switch terminals with high accuracy. . In some cases, it is not desired to provide an opening for cutting and raising the metal plate. In the structure in which the joining dowel described in Patent Document 2 is inserted into the dowel hole and the metal plate is locked, the metal plate is easily released and the metal plate is easily dropped.

本発明は、金属板にプレス加工と型鍛造によって板状部品の縁部を突入係止させる箇所が高精度で設けることができ、とくに、薄板金属製スイッチ端子等の電気・電子部品や精密機械部品等の取り付けに好適とされる、板状部品用係止部の成形方法と、この方法に拠る板状部品の係止構造と、この係止構造を備える板状部品の取付構造に関する。  The present invention can provide a metal plate with a high-precision location where the edge of a plate-like component is plunged into the metal plate by press working and die forging. In particular, electrical / electronic components such as thin metal switch terminals and precision machinery The present invention relates to a method for forming a plate-shaped component locking portion, which is suitable for mounting a component or the like, a plate-shaped component locking structure based on this method, and a plate-shaped component mounting structure including this locking structure.

課題を解決するための手段Means for solving the problem

請求項１に係る板状部品用係止部の成形方法は、金属板に接面させた板状部品の縁部を突入係止させる箇所の成形方法であって、該金属板の取付面に隣接する箇所をプレス加工して設けた凸段部に金型を用いた型鍛造を行って、該凸段部の前記板状部品を接触させる側になる側面の上部に前記取付面に向けた膨出部を設けて、該膨出部の下方箇所を前記金属板に接面させた前記板状部品の縁部を突入係止させる箇所とする成形方法である。  The method for forming a latching part for a plate-like component according to claim 1 is a molding method for a portion where the edge of the plate-like component brought into contact with the metal plate is plunged and locked to the mounting surface of the metal plate. Die forging using a die is performed on the convex step portion provided by pressing the adjacent portion, and the convex portion is directed to the mounting surface on the upper side surface on the side where the plate-like component is brought into contact. In this molding method, a bulging portion is provided, and a lower portion of the bulging portion is used as a portion where the edge of the plate-like component that is in contact with the metal plate is plunged and locked.

この成形方法の最も特徴的なところは、前記凸段部の前記板状部品を接触させる側になる側面の上部に前記取付面に向けた膨出部を設ける点と、この膨出部を型鍛造で成形する点にある。この成形方法は、金属板をプレス加工して前記凸段部を設ける工程と、この凸段部に型鍛造を行って該凸段部に前記膨出部を設ける工程を経る。前記膨出部は、前記凸段部の上面を鍛造して、該上面の金属材料組織の一部を前記膨出部が設けられる方向に移動させる方法で行われ、この鍛造が型鍛造で行われる。このようにして設けられた前記膨出部は突出部でもある。  The most characteristic feature of this molding method is that a bulging portion directed toward the mounting surface is provided on the upper portion of the side surface on the side where the plate-like component of the convex step portion is brought into contact, and the bulging portion is formed into a mold. It is in the point to form by forging. This forming method includes a step of pressing the metal plate to provide the protruding step portion, and a step of performing die forging on the protruding step portion and providing the protruding portion on the protruding step portion. The bulging portion is formed by forging the upper surface of the protruding step portion and moving a part of the metal material structure on the upper surface in a direction in which the bulging portion is provided. This forging is performed by die forging. Is called. The bulging part thus provided is also a protruding part.

前記凸段面の周囲を開放させた状態でその上面を上方から鍛造すると、該上面の金属材料組織の一部が四方に移動して前記膨出部の形状が不揃いになる。このため本発明では、前記膨出部の形状を決め、前記上面の金属材料組織の一部が該膨出部を設ける方向以外の方向に移動するのを防止させる側壁部を有する鍛造用の金型が使用される。前記膨出部を型鍛造して設けると、前記膨出部の下方に１ｍｍ以下の寸法の高さで突出方向に高さが低い膨出部を形成することも可能であり、高精度の膨出部が成形される。この膨出部の下方箇所は、薄板金属製スイッチ端子等の電気・電子部品や精密機械部品等の端部を係止させるのに好適な形状の後退した係止部となり、この係止部も高精度で形成される。  If the upper surface is forged from above with the periphery of the convex surface open, a part of the metal material structure on the upper surface moves in all directions, and the shape of the bulge becomes uneven. For this reason, in the present invention, forging gold having a side wall portion that determines the shape of the bulging portion and prevents a part of the metal material structure on the upper surface from moving in a direction other than the direction in which the bulging portion is provided. A type is used. When the bulging portion is provided by die forging, it is possible to form a bulging portion having a height of 1 mm or less and a low height in the protruding direction below the bulging portion. The exit is molded. The lower portion of the bulging portion is a retracted locking portion having a shape suitable for locking an end portion of an electrical / electronic component such as a sheet metal switch terminal or a precision machine component. Formed with high accuracy.

請求項２に係る板状部品用係止部の成形方法は、請求項１に係る板状部品用係止部の成形方法における前記型鍛造においては、前記凸段部に前記膨出させた部分を鍛造して設ける上型と、該凸段部の裏側の凹部に対応した凸部が設けられた下型とを用い、
前記上型には、前記膨出部を含む前記側面の形状を形作る側面部を有する横金型と、該凸段部の前記側面を除く他の側面に沿わせる内側側面部と該凸段部の上面を鍛造する内側上面部を有し、平面断面形状がコ字形状を有する鍛造用金型とを組み合わせたものを用いて、
前記横金型の前記側面部を前記凸段部の突出部が設けられる側面に対向させ、該側面を除く他の側面に該横金型又は前記鍛造用金型の側面部沿わせた状態で、前記鍛造用金型により該凸段部の上方から該凸段部の上面を鍛造して、前記凸段部の前記側面の上部に膨出部を設ける方法で行われる。According to a second aspect of the present invention, in the die forging in the molding method of the latching portion for the plate-like component according to the first aspect, the protruding part is the bulged portion. An upper die provided by forging and a lower die provided with a convex portion corresponding to the concave portion on the back side of the convex step portion,
The upper mold includes a horizontal mold having a side surface that forms the shape of the side surface including the bulging portion, an inner side surface portion that extends along the other side surface except the side surface of the convex step portion, and the convex step portion. Using a combination of a forging die having an inner upper surface portion for forging the upper surface of and having a U-shaped planar cross-sectional shape,
In a state where the side surface portion of the horizontal mold is opposed to the side surface on which the protruding portion of the convex step portion is provided, and the side surface portion of the horizontal mold or the forging die is aligned with the other side surface except the side surface. The upper surface of the convex step portion is forged from above the convex step portion by the forging die, and a bulging portion is provided at the upper portion of the side surface of the convex step portion.

前記横金型と平面断面形状がコ字形状を有する前記鍛造用金型とを組み合わせた前記上型は、前記膨出部の成形に適した金型にすることができる。前記型鍛造をした後は、前記横金型を前記凸段部から側方に離れる方向に移動させ、前記鍛造用金型を上方に移動させる。前記横金型は、鍛造時に平面断面形状がコ字形状を有する鍛造用金型の開放された側方を塞ぐ。平面断面形状がコ字形状の鍛造用金型は、前記板状部品の側縁部が直線形状を有する側縁部の係止に適する。  The upper mold obtained by combining the horizontal mold and the forging mold having a U-shaped cross-sectional shape can be a mold suitable for forming the bulging portion. After the die forging, the horizontal die is moved in a direction away from the convex step portion, and the forging die is moved upward. The horizontal die closes the opened side of the forging die having a U-shaped cross-sectional shape during forging. A forging die having a U-shaped planar cross-sectional shape is suitable for locking a side edge portion in which the side edge portion of the plate-like component has a linear shape.

請求項３に係る板状部品用係止部の成形方法は、請求項１又は２に係る板状部品用係止部の成形方法における前記プレス加工において、前記凸段部の裏側に形成される凹部の周縁に沿った部分に凹段部を設ける加工を行って該凸段部の上面を肉厚にする方法が更に加わる。  According to a third aspect of the present invention, there is provided a method for forming a plate-like component locking portion, which is formed on the back side of the convex step portion in the press working in the method for forming a plate-shaped component locking portion according to the first or second aspect.

前記凸段部の上面を鍛上方から鍛造して前記膨出部を設ける場合、該上面の金属組織の一部を膨出部が設けられる方向に移動させて行うため、該上面が肉薄になり易く、膨出部に金属材料組織が行き届かないおそれもある反面、前記凹部の周縁に沿った部分には厚みがある角部が形成される。このため、請求項３においては、前記プレス加工において、前記凹部の周縁の沿った部分に凹段部を形成して、この凹段部が形成されることにより減少する金属材料組織の相当量が前記上面に行き届くようにした。このため該上面は肉厚になり、前記膨出部が設けられる方向に十分な量の金属材料組織を行き届かせることが可能になる。  When the bulge is provided by forging the upper surface of the convex step from above forging, the upper surface becomes thin because a part of the metal structure of the upper surface is moved in the direction in which the bulge is provided. Although it is easy and the metal material structure may not reach the bulging portion, a corner portion having a thickness is formed in a portion along the peripheral edge of the concave portion. For this reason, in claim 3, in the press work, a concave step portion is formed in a portion along the peripheral edge of the concave portion, and a considerable amount of the metal material structure that is reduced by the formation of the concave step portion. It was made to reach the upper surface. For this reason, the upper surface becomes thick, and a sufficient amount of the metal material structure can be distributed in the direction in which the bulging portion is provided.
