Description

本発明は、リベット部材の足部を台金のリベット挿通孔に通し、その足部のリベット挿通孔から突出した部分をかしめることにより上記台金に上記リベット部材を固定してなり、このリベット部材の頭部の上面に、上記台金に対する特定の向きを有する特定のパターンが形成されたリベット台金複合品の製造方法と、その実施に用いるリベット部材と、その実施に用いるかしめ金型に関する。   According to the present invention, the rivet member is fixed to the base metal by passing the foot portion of the rivet member through the rivet insertion hole of the base metal and caulking the portion protruding from the rivet insertion hole of the base metal. The present invention relates to a manufacturing method of a rivet base metal composite product in which a specific pattern having a specific direction with respect to the base metal is formed on the upper surface of the head of the member, a rivet member used for the implementation, and a caulking die used for the implementation .

部品として、金属製のリベット部材の足部を台金のリベット挿通孔に通し、その足部のリベット挿通孔から突出した部分をかしめることにより上記台金に上記リベット部材を固定したリベット台金複合品がある(特開平10−223076号公報参照)。
そして、そのリベット台金複合品には、リベットの頭部表面に特定のパターン、例えば図4[(A)が平面図、(B)が(A)のB−B線視断面図、(C)が斜視図]に示すように、凸起状の一字状パターン(クロスバー)を有するものがある。
As a part, a rivet base metal in which a metal rivet member foot is passed through a rivet insertion hole of a base metal, and the rivet member is fixed to the base metal by caulking a portion protruding from the rivet insertion hole of the foot part. There is a composite product (see JP-A-10-223076).
The rivet base metal composite product has a specific pattern on the surface of the rivet head, for example, FIG. 4 [(A) is a plan view, (B) is a cross-sectional view taken along line BB in (A), (C ) Is a perspective view], and some have a protruding one-letter pattern (crossbar).

図面において、aは台金、bはこの台金aに形成されたリベット挿通孔、cはこの台金aに取り付けられるリベット部材、dはこのリベット部材cの頭部、eはリベット部材cの足部、fはリベット部材cの頭部dの上面に形成された突起からなるクロスバー(一字状の凸部)である。gはリベット部材cの上記リベット挿通孔bに通された足部eのこのリベット挿通孔bから突出しかしめられた部分である。
このようにクロスバーfを形成するのは、例えば各種スイッチの接点として用いるものの場合、そのリベット頭部と、それに接触して電気的接続関係が形成される相手方との間に異物(ゴミ等)、その他の不純物が介在して電気的導通不良を回避する等のためである。
In the drawing, a is a base, b is a rivet insertion hole formed in the base a, c is a rivet member attached to the base a, d is a head of the rivet member c, and e is a rivet member c. A foot part, f is a cross bar (one-letter-shaped convex part) made of a protrusion formed on the upper surface of the head part d of the rivet member c. Reference numeral g denotes a portion of the foot portion e that is passed through the rivet insertion hole b of the rivet member c and protrudes from the rivet insertion hole b.
For example, in the case where the cross bar f is used as a contact point of various switches, foreign matter (dust or the like) is formed between the rivet head and the other party in contact with the rivet to form an electrical connection relationship. This is for avoiding poor electrical continuity due to the presence of other impurities.

そして、そのパターンには、台金に対して特定の向きを有することが要求される場合が多い。例えば、図4に示す場合のように、クロスバーfの向きと台金aの長手方向の向きとが直交していることが要求される場合がある。また、図示はしないがクロスバーfの向きと台金aの向きとが同じであることが要求される場合もあり、更には、それ以外の要求がされる場合もある。どのような要求をするかは発注者の任意であり、受注者はその要求に正確に答えなければならない。   The pattern is often required to have a specific orientation with respect to the base metal. For example, as shown in FIG. 4, it may be required that the direction of the cross bar f and the direction of the longitudinal direction of the base metal a are orthogonal. Although not shown, there are cases where the direction of the crossbar f and the direction of the base metal a are required to be the same, and there are also cases where other requests are made. What kind of request is made is arbitrarily determined by the orderer, and the contractor must answer the request accurately.

そして、従来において、受注者はその発注者の要求に次のように応えていた。
リベット部材として、頭部dの上面にクロスバーfを形成したものcを用意し、かしめにあたって、そのリベット部材cの足部eを台金aのリベット挿通孔bに通すとき、リベット部材cの回転方向における向きを、注文に応じた向き(図4に示す例だと、クロスバーfの向きが台金aの長手方向と直交する向きになる向き)にし、その後、リベット部材cの頭部d側のかしめ用金型と、足部e側のかしめ用ポンチとによりかしめるというかしめ方法を採っていた。
特開平10−223076号公報
Conventionally, the contractor has responded to the request of the orderer as follows.
As a rivet member, a member c having a crossbar f formed on the upper surface of the head d is prepared, and when caulking, the leg portion e of the rivet member c is passed through the rivet insertion hole b of the base metal a. The direction in the rotation direction is the direction according to the order (in the example shown in FIG. 4, the direction in which the direction of the crossbar f is perpendicular to the longitudinal direction of the base metal a), and then the head of the rivet member c A caulking method of caulking with a caulking die on the d side and an caulking punch on the foot e side has been adopted.
JP-A-10-223076

ところで、頭部d上面にクロスバーf等のパターンを有するリベット部材cの足部eを、リベット部材cが特定の向きになるように台金aのリベット挿通孔bに挿入してかしめるという従来の技術によれば、足部eを、リベット部材cが台金aに対して特定の向きなるようにリベット挿通孔bに挿入するという作業が必要であり、面倒であり、作業性が悪く、生産性が低いという問題があった。また、向きに関する誤差が生じることも多かった。   By the way, it is said that the leg portion e of the rivet member c having a pattern such as a cross bar f on the upper surface of the head d is inserted into the rivet insertion hole b of the base metal a so that the rivet member c has a specific orientation. According to the prior art, it is necessary to insert the foot e into the rivet insertion hole b so that the rivet member c is in a specific direction with respect to the base metal a, which is troublesome and poor in workability. There was a problem of low productivity. Also, errors related to the orientation often occurred.

また、セットした段階では誤差が少なかったが加圧によりかしめたときに向きにずれが生じてしまう可能性もあった。
向きの誤差が仕様による許容範囲を超えた場合には、当然に不良品となり、歩留まり低下を招く。これ等はリベット台金複合品の低価格化を阻む要因になっていた。
In addition, there was little error at the stage of setting, but there was a possibility that the direction could be shifted when crimped by pressurization.
If the error in the direction exceeds the allowable range according to the specification, it will naturally become a defective product, leading to a decrease in yield. These were factors that hindered the price reduction of rivet base metal composites.

本発明は、このような問題を解決するためのもので、リベット部材の足部を台金のリベット挿通孔に通し、その足部のリベット挿通孔から突出した部分をかしめることにより上記台金に上記リベット部材を固定してなり、このリベット部材の頭部の上面に、上記台金に対する特定の向きを有する特定のパターンが形成されたリベット台金複合品の生産性を高め、不良品の発生率を低めて歩留まりの向上を図り、リベット台金複合品の低価格化を可能にすることのできる新規なリベット台金複合品の製造方法と、その製造に用いる新規なリベット部材と、新規なかしめ金型とを提供することを目的とする。   The present invention is to solve such a problem. The base metal is formed by passing a foot portion of a rivet member through a rivet insertion hole of the base metal and caulking a portion protruding from the rivet insertion hole of the base metal portion.
