Description

本発明は、プレス金型のダイ上に載置した板状ワークを固定する位置決めコマに関するものである。 The present invention relates to a positioning piece for fixing a plate-like workpiece placed on a die of a press die.

従来、プレス金型では、図４および図５に示すように、ダイ上面Ａの所定位置に板状ワークＢを載置固定してプレス作業を行うが、この際、上記ワークＢの載置位置の周囲に位置決めコマＣ、Ｃ…を配置し、円柱状のピン部Ｄの周面にワークＢの外縁を当接させる事により、ワークＢの固定を行うようにしている。 Conventionally, in a press die, as shown in FIGS. 4 and 5, the plate work B is placed and fixed at a predetermined position on the die upper surface A, and the press work is performed. .. Are disposed around the outer periphery of the workpiece B, and the workpiece B is fixed by bringing the outer edge of the workpiece B into contact with the peripheral surface of the cylindrical pin portion D.

しかしながら、上記構成のような位置決めコマＣ、Ｃ…によるワークＢの固定では、当該ワークＢの形状の大小に合わせて、図４（ｃ）〜（ｆ）に示すように、直径の異なる円柱状のピン部Ｄ１、Ｄ２を形成した位置決めコマＣ１、Ｃ２に、その都度いちいち交換しなければならず、また、ワークＢの形状に合致する位置決めコマがない場合には、図５（ａ）〜（ｆ）に示すように、ワークＢの形状に合わせて四角柱状の各位置決めコマＣ、Ｃ…の当接面Ｅをそれぞれ切削する、等の準備作業を要し、より精度の高いプレス製品を短納期、低価格で要求される今日において、上述のような煩わしい交換、調整作業を必要としないプレス金型の位置決めコマが需要者から熱望されていた。 However, when the workpiece B is fixed by the positioning pieces C, C... As described above, as shown in FIGS. 4 (c) to 4 (f), the cylindrical shapes having different diameters are matched to the size of the workpiece B. If the positioning pieces C1 and C2 formed with the pin portions D1 and D2 have to be replaced each time, and there is no positioning piece that matches the shape of the workpiece B, FIGS. As shown in f), preparation work such as cutting the contact surface E of each of the square columnar positioning pieces C, C... according to the shape of the work B is required, and a highly accurate press product can be shortened. In today's demanded delivery time and low price, positioning dies for press dies that do not require such troublesome replacement and adjustment operations have been eagerly desired by customers.

一方、プレス機械のボルスター上に設置される複数のプレス金型の相互位置を、迅速かつ正確に確保するようにした提案がなされている。
特開平５−１４６８３３ この提案では、人手を介して人為的にプレス金型を度当りピンに押し当てることなく、複数のプレス金型の相互位置に生じるバラツキを一掃しつつ、金型設置に要する調整時間を短縮することができるものの、プレス金型のダイ上に載置したワーク本体の位置決めに対しては何ら改善策とはならないものであった。 On the other hand, proposals have been made to ensure the mutual position of a plurality of press dies installed on a bolster of a press machine quickly and accurately.
In this proposal, it is necessary to install the dies while eliminating the variation occurring at the mutual positions of the plurality of press dies without manually pressing the press dies against the pins. Although the adjustment time can be shortened, there is no improvement measure for positioning the work body placed on the die of the press die.

本発明は、上記の如き実状に鑑みプレス金型における精度の高いワーク固定を追究する研究、開発の過程で創案されたものであって、その意図するところは、ワークの形状が大小異なる場合にも、同一の位置決めコマを用いて容易かつ正確に位置決めを行うことができるプレス金型における調整可能な位置決めコマを提供しようとするものである。 The present invention was devised in the course of research and development for pursuing high-precision work fixing in press dies in view of the actual situation as described above, and its intended purpose is when the shape of the work is different in size. Furthermore, an object of the present invention is to provide an adjustable positioning piece in a press die that can be easily and accurately positioned using the same positioning piece.

課題を解決するため本発明が採用した技術手段は、ダイ上に載置した板状ワークの四周縁を、その周囲に着脱自在に植立した位置決めコマの側面に当接させてダイ上に固定するに、断面正多角形をなす差込柱体と、当該差込柱体と同一面数で位置決め周面を形成したピン部を構成部材として、上記差込柱体の周面と位置決め周面を段差部を介して平行し、かつ当該各面毎の平行段差間隔をそれぞれ相違させたことを特徴とするものである。 In order to solve the problem, the technical means adopted by the present invention is to fix the four peripheral edges of the plate-like workpiece placed on the die to the side of the positioning piece detachably planted around the workpiece and fix it on the die. In particular, an insertion column having a regular polygonal cross section and a pin part having a positioning peripheral surface formed with the same number of faces as the insertion column, and the peripheral surface of the insertion column and the positioning peripheral surface. Are parallel to each other through the step portion, and the parallel step interval for each surface is made different.

したがって、本発明によれば、プレス金型内にワークを載置固定する当たり、位置決めコマの追加工、交換等の煩わしい作業を要することなく、プレス作業の初期に装着した位置決めコマをそのまま利用して、ワークの位置調整および固定作業を短時間でスムーズに行うことができ、形状の異なるワークに対して精度の高いプレス作業を連続して行うことができる。 Therefore, according to the present invention, when the work is placed and fixed in the press die, the positioning piece mounted at the initial stage of the press work is used as it is without requiring any troublesome work such as additional machining and replacement of the positioning piece. Thus, the work position adjustment and fixing work can be performed smoothly in a short time, and highly accurate press work can be continuously performed on work pieces having different shapes.

複数の同一平面で断面正多角形の差込柱体を形成した基部の上面に、当該差込柱体と同一面数を有して多面状の位置決め周面を形成したピン部を一体形成して位置決めコマを構成するに際して、上記差込柱体の周面と位置決め周面を段差部を介して平行し、かつ各面毎の平行段差間隔をそれぞれ相違させた。 A pin portion having the same number of faces as that of the insertion post body and having a multi-faceted positioning peripheral surface is integrally formed on the upper surface of the base portion in which a plurality of insertion post bodies having a regular polygonal cross section are formed on the same plane. When the positioning piece is configured, the peripheral surface of the insertion column and the positioning peripheral surface are parallel to each other through the step portion, and the parallel step interval for each surface is made different.

By configuring each of the positioning pieces 11 to 15 so that the step intervals d1 to d8 are all different, it is possible to finely adjust the positioning of the workpiece according to the purpose and purpose of the product to be pressed by the consumer. Become.

ダイ１側に設けた複数の装着孔２、２…に、位置決めコマ９の挿脱機構と面位置切替機構を内装して自動化制御を行うように構成すれば、さらにワークの位置調整および固定作業を短時間でスムーズに行うことが可能になる。 If a plurality of mounting holes 2, 2... Provided on the die 1 side are equipped with an insertion / removal mechanism for the positioning piece 9 and a surface position switching mechanism to perform automation control, the work position adjustment and fixing work are further performed. Can be carried out smoothly in a short time.
