Description

この発明は、上型を下型に対して水平方向の位置決めするための位置決め治具,金型及びプレス装置に関する。   The present invention relates to a positioning jig, a mold, and a press device for positioning an upper mold in a horizontal direction with respect to a lower mold.

例えば、非特許文献1及び非特許文献2等に記載されているように、金型は、ガイドポストに昇降自在に位置決めされた上型とこの上型と対向配置された下型とで構成され、上型はプレス装置のスライドの下端に取付けられ、下型はプレス装置のボルスタ上に固定されている。そして、かかる構成により、プレス装置のスライドを下降させ、金型の上型をガイドポストに嵌められたスプリングに抗して押し下げることで、下型に対するプレス加工を行なうことができるようになっている。   For example, as described in Non-Patent Document 1, Non-Patent Document 2, and the like, the mold is composed of an upper mold positioned so as to be movable up and down on the guide post and a lower mold disposed opposite to the upper mold. The upper die is attached to the lower end of the slide of the press device, and the lower die is fixed on the bolster of the press device. With this configuration, the lower die can be pressed by lowering the slide of the press device and pushing down the upper die against the spring fitted in the guide post. .

武藤一夫等著「金型設計・加工技術」日刊工業新聞社、2004年5月20日発行p17−p34"Mold design and processing technology" written by Kazuo Muto et al., Nikkan Kogyo Shimbun, May 20, 2004, p17-p34 アイダ・プレス研究会著「知りたいプレス機械」ジャパンマシニスト社、1999年8月31日発行p55−p86"Press machine you want to know" written by Aida Press Research Group, Japan Machinist, published on August 31, 1999 p55-p86

しかし、プレス装置においては、スライドをクランクを用いて昇降させるので、スライドは、ボルスタに対し完全な直角ではなく、微少な変位を伴ないながら昇降運動を行なう。このスライダの変位量と変位方向はプレスの種類や回転数,使用条件等によって千差万別であり、常にその変化は金型の精度に影響を与え、ガイドポストの偏摩耗や型カジリといったトラブルを発生させ、金型寿命に大きく影響を与える問題があった。
かかる問題は、ミクロンやナノの単位の精度が要求される精密金型では致命的な問題であった。このため、精密金型では、ガイドポストを太くして、プレス装置のスライドの影響を可能な限り少なくするしたり、高精度なプレス装置を購入して、しかも古くなってスライドの変位が大きくなる前に、新しい高精度なプレス装置を購入するという工夫がなされていた。しかし、かかる工夫では、金型やプレス装置の製造や購入に多大なコストがかかってしまう。
これに対し、いわゆる「たたき」という方式の金型がある。この金型は、上型をプレス装置のスライドに取り付けずに使用する金型であり、上型の上面中央に突設したシャンクのような部分を有する。そして、スライドをこの突設部分にたたきつけて上型に均一な押圧力を与えることができる金型である。この金型の場合には、スライドの押圧力が上型の突設部分に集中するので、スライドの変位の影響を受け難い。しかしながら、スライドによって下降された上型を、ガイドボストに装着されたスプリングあるいは金型に設けられたスプリングの復旧力によって上昇させる構造であるので、上型の戻りが遅くなる。このため、スライドを高速に昇降させてプレス加工を行なうことができず、その分製品の生産タクトが低下してしまう。
However, in the press device, since the slide is moved up and down using a crank, the slide moves up and down with a slight displacement rather than being completely perpendicular to the bolster. The amount and direction of displacement of this slider varies greatly depending on the type of press, the number of revolutions, the operating conditions, etc., and these changes always affect the accuracy of the mold, causing problems such as uneven wear on the guide post and mold galling. There is a problem that greatly affects the mold life.
Such a problem is a fatal problem in precision molds that require precision in units of microns and nanometers. For this reason, in precision molds, the guide post is thickened to reduce the influence of the slide of the press device as much as possible, or a high-precision press device is purchased. Previously, a device was devised to purchase a new high-precision press. However, with such a device, a great deal of cost is required for the manufacture and purchase of molds and press devices.
On the other hand, there is a so-called “tapping” mold. This die is a die that is used without attaching the upper die to the slide of the press device, and has a shank-like portion protruding from the center of the upper surface of the upper die. And it is a metal mold | die which can strike a slide against this protrusion part and can give a uniform pressing force to an upper mold | type. In the case of this mold, the slide pressing force is concentrated on the projecting portion of the upper mold, so that it is difficult to be affected by the slide displacement. However, since the upper die lowered by the slide is raised by the restoring force of the spring mounted on the guide post or the spring provided on the die, the return of the upper die is delayed. For this reason, the slide cannot be moved up and down at a high speed and the press working cannot be performed, and the production tact of the product is reduced accordingly.

この発明は、上述した課題を解決するためになされたもので、プレス装置のスライドの変位を吸収して、金型の上型を水平に位置決め保持可能な位置決め治具,金型及びプレス装置を提供することを目的とする。   The present invention has been made to solve the above-described problems, and includes a positioning jig, a mold, and a press apparatus that can absorb the displacement of the slide of the press apparatus and can position and hold the upper mold of the mold horizontally. The purpose is to provide.

上記課題を解決するために、請求項1の発明に係るコンデンサ実装構造は、プレス装置のスライドに取り付けるための上取付部と、金型の上型に取り付けるための下取付部と、上取付部の下面に突設された垂下部の先端に設けられ且つ垂下部よりも大径の球状部を、下取付部に形成された収納部に回動自在に収納して上取付部と下取付部とを連結したジョイント部とを備える構成とした。
かかる構成により、位置決め治具の上取り付け部をプレス装置のスライドに取り付けると共に下取付部を金型の上型に取り付けることができる。そして、これら上取付部と下取付部がジョイント部で連結されているので、スライドを昇降させると、金型の上型もスライドに同期して昇降する。このとき、スライドが変位すると、上取付部も変位するが、上取付部に突設された球状部がスライドの変位に対応して回動するため、下取付部は変位せず水平位置を保つ。この結果、上型も変位せず水平な位置を保持して昇降する。
In order to solve the above problems, a capacitor mounting structure according to the invention of claim 1 includes an upper mounting portion for mounting on a slide of a press device, a lower mounting portion for mounting on an upper mold of a mold, and an upper mounting portion.

And a joint portion connected to each other.
With this configuration, the upper attachment portion of the positioning jig can be attached to the slide of the press device and the lower attachment portion can be attached to the upper die of the mold. And since these upper attachment parts and lower attachment parts are connected by the joint part, if a slide is raised / lowered, the upper mold | type of a metal mold will also raise / lower synchronously with a slide. At this time, when the slide is displaced, the upper mounting portion is also displaced. However, since the spherical portion projecting from the upper mounting portion rotates corresponding to the displacement of the slide, the lower mounting portion is not displaced and maintains the horizontal position. . As a result, the upper mold also moves up and down while maintaining a horizontal position without being displaced.

請求項2の発明は、請求項1に記載の位置決め治具において、ジョイント部の収納部を、下取付部の上面に凹設され球状部の下半球とほぼ同形の第1凹部と、保持部材の下面に凹設され球状部の上半球とほぼ同形の第2凹部と、第2凹部の上部と連通した状態で保持部材の上面に開口した挿通孔とで構成し、垂下部を挿通孔に挿通させた状態で、その先端の球状部を第1及び第2凹部で上下から挟み込むことにより、ジョイント部を構成した。   According to a second aspect of the present invention, in the positioning jig according to the first aspect, the storage portion of the joint portion is recessed on the upper surface of the lower mounting portion and is substantially the same shape as the lower hemisphere of the spherical portion, and the holding member A second concave portion that is recessed in the lower surface of the spherical portion and is substantially the same shape as the upper hemisphere of the spherical portion, and an insertion hole that opens to the upper surface of the holding member in communication with the upper portion of the second concave portion.

かかる構成により、位置決め治具の上取付部をプレス装置のスライドに取り付けると共に下取付部を金型の上型に取り付けることができる。そして、これら上取付部と下取付部がジョイント部で連結されているので、スライドを昇降させると、金型の上型もスライドに同期して昇降する。このとき、スライドが変位すると、上取付部が第1軸体周りで回動して変位を吸収し、下取付部が変位せず水平位置を保つ。この結果、上型も変位せず水平な位置を保持して昇降する。
According to a fourth aspect of the present invention, there is provided an upper mounting portion for mounting on a slide of a press device, a lower mounting portion for mounting on an upper mold of a mold, and a rod-shaped first shaft mounted in parallel to the lower surface of the upper mounting portion. The body is attached to a shaft insertion portion projecting from the upper surface of the lower attachment portion, and the upper attachment portion and the lower attachment portion are connected to each other so as to be rotatable around the first shaft body. .
With this configuration, the upper attachment portion of the positioning jig can be attached to the slide of the press device and the lower attachment portion can be attached to the upper die of the mold. And since these upper attachment parts and lower attachment parts are connected by the joint part, if a slide is raised / lowered, the upper mold | type of a metal mold will also raise / lower synchronously with a slide. At this time, when the slide is displaced, the upper mounting portion rotates around the first shaft body to absorb the displacement, and the lower mounting portion is not displaced and maintains the horizontal position. As a result, the upper mold also moves up and down while maintaining a horizontal position without being displaced.

請求項5の発明は、請求項4に記載の位置決め治具において、第1軸体を、中間部材の上面に突設された軸挿入部に取り付けると共に、中間部材の下面に平行であって且つ第1軸体と直角方向を向くように取り付けられた棒状の第2軸体を、下取付部の上面に突設された軸挿入部に取り付けて、上取付部と下取付部とを第1軸体の周り及び第2軸体周りで回動できるように連結した構成とする。
かかる構成により、スライドが変位すると、それに対応して、上取付部が第1及び第2軸体の周りで回動してスライドの変位を吸収する。この結果、下取付部が変位せず水平位置を保つので、上型も変位せず水平な位置を保持して昇降する。

The shaft body and the second shaft body are connected so as to be rotatable.
With this configuration, when the slide is displaced, the upper mounting portion rotates correspondingly around the first and second shaft bodies to absorb the displacement of the slide. As a result, the lower mounting portion is not displaced and maintains the horizontal position, so that the upper die is also moved up and down while maintaining the horizontal position without being displaced.

かかる構成により、スライドが変位すると、それに対応して、上取付部の垂下レール部が下取付部の収納部内で摺動して、スライドの変位を吸収する。この結果、下取付部が変位せず水平位置を保つので、上型も変位せず水平な位置を保持して昇降する。
The invention according to claim 6 is an upper mounting portion for mounting on the slide of the press device, a lower mounting portion for mounting on the upper die of the mold, and a rail-like projecting surface on the lower surface of the upper mounting portion. The hanging rail portion having a wide and substantially semicircular portion is slidably housed in a housing portion formed in the lower mounting portion, and includes a joint portion that connects the upper mounting portion and the lower mounting portion. .
With this configuration, when the slide is displaced, the hanging rail portion of the upper mounting portion correspondingly slides within the storage portion of the lower mounting portion to absorb the displacement of the slide. As a result, the lower mounting portion is not displaced and maintains the horizontal position, so that the upper die is also moved up and down while maintaining the horizontal position without being displaced.

請求項7の発明は、請求項6に記載の位置決め治具において、ジョイント部の収納部を、下取付部の上面に凹設され且つ垂下レール部の先端部の先端面形状とほぼ同形の第1溝部と、保持部材の下面に凹設され先端部を収納可能な第2溝部と、第2溝部の上部と連通した状態で保持部材の上面に開口した挿通溝とで構成し、垂下レール部の首部を挿通溝に挿通させ且つ先端部の先端面を第1溝部に当接させた状態で、先端部を第1及び第2溝部で上下から抱え込むことにより、ジョイント部を構成した。   According to a seventh aspect of the present invention, in the positioning jig according to the sixth aspect of the present invention, the storage portion of the joint portion is recessed on the upper surface of the lower mounting portion and is substantially the same shape as the distal end surface shape of the distal end portion of the hanging rail portion.

以上詳しく説明したように、請求項1ないし請求項8の発明に係る位置決め治具によれば、スライドの変位をジョイント部の作用によって吸収し、スライドの変位を上型に伝えない構成であるので、金型の上型を常に水平に保持することができる。このため、精密金型の精度を維持向上させることができると共に、金型のガイドポストの偏摩耗や型カジリといったトラブルの防止と金型の長寿命化を図ることができる。この結果、精密金型において、ガイドポストを太くしたり、高精度なプレス装置を頻繁に買い換える必要がなくなり、金型の軽量化や金型及びプレス装置の製造や購入の低コスト化に貢献することができる。さらに、上取付部と下取付部とがジョイント部で連結されているので、上取付部が取り付けられたスライドの昇降運動が、下取付部が取り付けられた上型に直接伝わり、上型がスライドに同期して昇降する。このため、いわゆる「たたき」という方式の金型と異なり、スライド及び上型の高速昇降が可能となり、その分製品の生産タクトの向上を図ることができる。また、この位置決め治具は、上取付部をスライドに取り付け、下取付部を上型に取り付けるだけで使用することができる。このため、プレス装置や金型の種類に影響されず、あらゆる種類のプレス装置や金型に用いることができるので、汎用性が非常に高い。   As described above in detail, the positioning jig according to the inventions of claims 1 to 8 is configured to absorb the displacement of the slide by the action of the joint portion and not transmit the displacement of the slide to the upper mold. The upper mold of the mold can always be held horizontally. As a result, the precision of the precision mold can be maintained and improved, and troubles such as uneven wear of the mold guide posts and mold galling can be prevented and the life of the mold can be extended. As a result, there is no need to increase the thickness of the guide post or to replace the high-precision press device frequently in precision molds, which contributes to lighter molds and lower costs for manufacturing and purchasing molds and press devices. be able to. Furthermore, since the upper mounting part and the lower mounting part are connected by a joint part, the up-and-down movement of the slide to which the upper mounting part is attached is directly transmitted to the upper mold to which the lower mounting part is attached, and the upper mold slides. Ascends and descends synchronously. Therefore, unlike a so-called “tapping” mold, the slide and the upper mold can be moved up and down at a high speed, and the production tact of the product can be improved accordingly. The positioning jig can be used simply by attaching the upper attachment portion to the slide and attaching the lower attachment portion to the upper mold. For this reason, since it can be used for all kinds of press apparatuses and metal molds without being influenced by the types of press apparatuses and metal molds, the versatility is very high.

図1は、この発明の第1実施例に係る位置決め治具を示す断面図であり、図2は、図1に示す位置決め治具の分解斜視図であり、図3は、ジョイント部を示す部分拡大断面図であり、図4は、上取付部の変位状態を示す断面図である。   1 is a sectional view showing a positioning jig according to a first embodiment of the present invention, FIG. 2 is an exploded perspective view of the positioning jig shown in FIG. 1, and FIG. 3 is a part showing a joint portion. FIG. 4 is an enlarged cross-sectional view, and FIG. 4 is a cross-sectional view showing a displacement state of the upper mounting portion.

図1に示すように、この位置決め治具1は、上取付部2と下取付部3とジョイント部4とを備えている。   As shown in FIG. 1, the positioning jig 1 includes an upper mounting portion 2, a lower mounting portion 3, and a joint portion 4.

The joint portion 4 is a member for connecting the upper mounting portion 2 and the lower mounting portion 3.
Specifically, as shown in FIG. 3, a hole 21 is provided in the center of the lower surface 2 b of the upper mounting portion 2, and a columnar hanging portion 40 is press-fitted into the hole 21. The drooping portion 40 is fixed by the bolt 22 and protrudes from the lower surface of the upper mounting portion 2. Further, a spherical portion 41 having a larger diameter than the hanging portion 40 is formed at the tip of the hanging portion 40, and the spherical portion 41 can be freely rotated by a storage portion 45 formed on the lower mounting portion 3 side. It is stored.

この収納部45は、下取付部3に凹設された第1凹部46と、保持部材5に凹設及び穿設された第2凹部47及び挿通孔48とで構成されている。詳細には、球状部41の下半球とほぼ同形に設定された第1凹部46が下取付部3の上面3aの中央部に形成され、球状部41の上半球とほぼ同形の第2凹部47が保持部材5の下面5bの中央部に形成されている。さらに、垂下部40よりも若干大径の挿通孔48が第2凹部47の上部から保持部材5の上面に向かった穿設されて、挿通孔48が第2凹部47の上部と連通した状態で保持部材5の上面5aに開口している。   The storage portion 45 includes a first recess 46 that is recessed in the lower mounting portion 3, and a second recess 47 and an insertion hole 48 that are recessed and drilled in the holding member 5. More specifically, a first recess 46 that is set to be approximately the same shape as the lower hemisphere of the spherical portion 41 is formed at the center of the upper surface 3a of the lower mounting portion 3, and a second recess 47 that is approximately the same shape as the upper hemisphere of the spherical portion 41. Is formed at the center of the lower surface 5 b of the holding member 5.

図5に示すように、位置決め治具1は、プレス装置100のスライド110と金型200の上型210との間に取り付けて使用することができる。
具体的には、図6に示すように、位置決め治具1の上取付部2をボルト23でスライド110の下端に固定する。そして、ボルスタ120(図5参照)上に載置された金型200の上型210に、下取付部3をボルト33で固定する。なお、この実施例では、上取付部2をスライド110に直接固定した例を示したが、スライド110の下端に別体のボルスタを固定し、そのボルスタに上取付部2を固定するようにしても良いことは勿論である。
このように、この実施例の位置決め治具1は、上取付部2や下取付部3をスライド110や上型210に固定するだけで取り付けることができるので、プレス装置や金型の種類にかかわらず、あらゆる種類のプレス装置や金型に取り付けることができ、汎用性が高い。
Next, a usage example of the positioning jig 1 of this embodiment will be described.
FIG. 5 is a schematic view showing an example of use of the positioning jig 1 of this embodiment, FIG. 6 is a cross-sectional view showing a mounting state of the positioning jig 1, and FIG. 7 is a cross-section showing a displacement absorbing action. FIG.
As shown in FIG. 5, the positioning jig 1 can be used by being attached between the slide 110 of the press device 100 and the upper mold 210 of the mold 200.
Specifically, as shown in FIG. 6, the upper mounting portion 2 of the positioning jig 1 is fixed to the lower end of the slide 110 with a bolt 23. And the lower attachment part 3 is fixed to the upper mold | type 210 of the metal mold | die 200 mounted on the bolster 120 (refer FIG. 5) with the volt | bolt 33. FIG. In this embodiment, the upper mounting portion 2 is directly fixed to the slide 110. However, a separate bolster is fixed to the lower end of the slide 110, and the upper mounting portion 2 is fixed to the bolster. Of course, it is also good.
As described above, the positioning jig 1 of this embodiment can be mounted simply by fixing the upper mounting portion 2 and the lower mounting portion 3 to the slide 110 and the upper mold 210. It can be attached to all kinds of press machines and dies, and is highly versatile.

位置決め治具1をスライド110と上型210とに取り付けた状態において、プレス装置100を作動させると、スライド110が図6の矢印で示すように昇降運動する。このとき、上取付部2と下取付部3とがジョイント部4によって連結されているので、スライド110の押下力が位置決め治具1を通じて上型210に伝搬される。また、スライド110が上昇すると、下取付部3がジョイント部4を通じて持ち上げられるので、上型210もスライド110の上昇に伴って上昇する。
すなわち、この実施例の位置決め治具1を使用することで、金型200の上型210がプレス装置100のスライド110と同期して昇降するので、上述した「たたき」方式のように、上型210の上昇が遅れるという事態は生じない。このため、生産タクトの向上を図ることができる。
When the press device 100 is operated in a state where the positioning jig 1 is attached to the slide 110 and the upper mold 210, the slide 110 moves up and down as indicated by the arrows in FIG. At this time, since the upper mounting portion 2 and the lower mounting portion 3 are connected by the joint portion 4, the pressing force of the slide 110 is transmitted to the upper mold 210 through the positioning jig 1. Further, when the slide 110 rises, the lower mounting portion 3 is lifted through the joint portion 4, so that the upper mold 210 also rises as the slide 110 rises.
That is, by using the positioning jig 1 of this embodiment, the upper mold 210 of the mold 200 moves up and down in synchronism with the slide 110 of the press apparatus 100, so that the upper mold as in the above-described “tapping” method. The situation where the rise of 210 is delayed does not occur. For this reason, the production tact can be improved.

ところで、かかる昇降動作時に、スライド110が上型210に対して直角に昇降せず、図7に示すように、スライド110が複雑に変位しながら昇降する事態が発生する。かかる場合には、スライド110に固定された上取付部2が変位し、ジョイント部4の球状部41が収納部45内でスライド110の変位に対応した回動を行なう。これにより、上取付部2の回動力は下取付部3に伝わらない。つまり、スライド110の複雑な変位はジョイント部4によって吸収され、上型210が水平な状態を維持する。この結果、プレス装置100と金型200とによる高精度なプレス加工が実現される。   By the way, at the time of this raising / lowering operation, the slide 110 does not move up and down at right angles with respect to the upper mold 210, and as shown in FIG. In such a case, the upper mounting portion 2 fixed to the slide 110 is displaced, and the spherical portion 41 of the joint portion 4 rotates within the storage portion 45 corresponding to the displacement of the slide 110. Thereby, the rotational force of the upper mounting portion 2 is not transmitted to the lower mounting portion 3. That is, the complicated displacement of the slide 110 is absorbed by the joint part 4, and the upper mold | type 210 maintains a horizontal state. As a result, high-precision pressing with the press device 100 and the mold 200 is realized.

Then, the first shaft body 42 was inserted into the hole 43 a of the shaft insertion portion 43 protruding from the upper surface 6 a of the intermediate member 6, and the intermediate member 6 was connected to the upper mounting portion 2. Further, bearings 61, 61 that face the bearings 51, 51 at right angles to the lower surface 6 b of the intermediate member 6 were formed, and both ends of the second shaft body 62 were supported by these bearings 61, 61. As a result, the first shaft body 42 and the second shaft body 62 are oriented in a direction perpendicular to each other.
