Description

本発明は金属加工等に用いるパンチング（タレットパンチプレス）金型の着脱機構に関するものである。   The present invention relates to a mechanism for attaching / detaching a punching (turret punch press) mold used for metal processing or the like.

従来、パンチング金型の着脱機構としては、図１と図２に示すように、上端にネジを設けたパンチボディ１、リング状のスプリングリテナー２、スプリング３、下端にネジを設けたヘッド４、ガイド５とによって構成されており、パンチボディ１をガイド５に着脱可能に取り付ける機構としては、スプリングリテナー２の外周面にＯリング６を設けるとともに、ガイド５の鍔部の内周面に溝７を設け、ガイド５をスプリングリテナー２に装着するについては、パンチボディ１に挿着されているガイド５を上方に摺動させて、ガイド５の溝７をスプリングリテナー２のＯリング６に嵌め込み、また、ガイド５をスプリングリテナー２から脱離するについては、ガイド５を下方に摺動させて、ガイド５の溝をスプリングリテナー２のＯリング６より外して、図１に示す状態に戻すものが多く、特開平６−２７８０９６号のパンチング金型もこの着脱機構を採用している。 Conventionally, as shown in FIGS. 1 and 2, a punching die attaching / detaching mechanism includes a punch body 1 provided with a screw at the upper end, a ring-shaped spring retainer 2, a spring 3, a head 4 provided with a screw at the lower end, As a mechanism for detachably attaching the punch body 1 to the guide 5, an O-ring 6 is provided on the outer peripheral surface of the spring retainer 2, and a groove 7 is formed on the inner peripheral surface of the flange portion of the guide 5. The guide 5 is attached to the spring retainer 2 by sliding the guide 5 inserted in the punch body 1 upward and fitting the groove 7 of the guide 5 into the O-ring 6 of the spring retainer 2. In order to detach the guide 5 from the spring retainer 2, the guide 5 is slid downward so that the groove of the guide 5 is separated from the O-ring 6 of the spring retainer 2.

特開平６−２７８０９６号JP-A-6-278096

しかし、前述したパンチング金型の着脱機構においては、ガイド５の溝をスプリングリテナー２のＯリング６に嵌め込む際に、Ｏリング６を変形させるという大きな力でガイド５を圧入する必要があるために、作業効率が悪い欠点があり、特に、ガイド５の溝７をスプリングリテナー２のＯリング６より外す際には、ガイド５とスプリングリテナー２の間にドライバー等の工具を差し込んで、テコの原理でガイド５をスプリングリテナー２から脱離することが多く、作業効率が一段と悪化するばかりか、ガイド５やスプリングリテナー２を損傷するおそれもあり、また、Ｏリング６の劣化によって、外力を加えない時でも、ガイド５とスプリングリテナー２が脱離する不都合があった。   However, in the punching mold attaching / detaching mechanism described above, when the groove of the guide 5 is fitted into the O-ring 6 of the spring retainer 2, it is necessary to press-fit the guide 5 with a large force that deforms the O-ring 6. In addition, there is a disadvantage that the working efficiency is bad. Especially, when removing the groove 7 of the guide 5 from the O-ring 6 of the spring retainer 2, a tool such as a screwdriver is inserted between the guide 5 and the spring retainer 2, In principle, the guide 5 is often detached from the spring retainer 2, and not only the working efficiency is further deteriorated, but also the guide 5 and the spring retainer 2 may be damaged, and an external force is applied due to the deterioration of the O-ring 6. Even when there was not, there was a problem that the guide 5 and the spring retainer 2 were detached.

本発明は、パンチング金型の着脱機構において、従来のように、Ｏリングを変形させるという大きな力を必要とせずに、簡単な操作で、作業効率よく、確実に、パンチング金型のガイドとスプリングリテナーの着脱を行うことに目的があり、特に、ガイドの溝をスプリングリテナーのＯリングより外す際に、ガイドとスプリングリテナーの間にドライバー等を差し込むような余計な作業や工具等を使用することなく、ガイドやスプリングリテナーを損傷せずに、ガイドをスプリングリテナーから取り外すことに目的がある。 The present invention provides a punching mold guide and spring that is simple and easy to operate, and does not require a large force to deform the O-ring in the punching mold attaching / detaching mechanism. The purpose is to attach and detach the retainer. Especially, when removing the guide groove from the O-ring of the spring retainer, use extra work and tools that insert a screwdriver between the guide and the spring retainer. The purpose is to remove the guide from the spring retainer without damaging the guide or spring retainer.

本発明は、パンチボディ、リング状のスプリングリテナー、スプリング、ヘッド、ガイドとによって構成したパンチング金型の着脱機構に関するもので、スプリングリテナーの外側円周面に内溝を設け、ガイドの鍔部の内側円周面に外溝を設けるとともに、ガイドの鍔部の外側円周面に押しピンを取り付け、このスプリングリテナーの内溝とガイドの鍔部の外溝に楕円形のバネを嵌め込むについては、楕円形のバネの長手方向の一部分を、押しピンを取り付けたガイドの鍔部の外溝に嵌め込むとともに、楕円形のバネの長手方向の他部分を、押しピンを取り付けた反対側のガイドの鍔部の外溝に嵌め込み、かつ、楕円形のバネの短手方向の一部分と他部分を、スプリングリテナーの内溝に嵌め込むことによって、スプリングリテナーをガイド内に挿着する準備状態を形成し、次いで、スプリングリテナーをガイド内に挿着するについては、ガイドの鍔部に取り付けた押しピンを押圧して、楕円形のバネを円形に変形させることによって、楕円形のバネの短長手方向の一部分と他部分を、ガイドの鍔部の外溝に嵌め込み、バネの短手方向の一部分と他部分をスプリングリテナーの内溝に掛からない状態にして、スプリングリテナーをガイド内に挿入した後、押しピンの押圧を解除して、円形に変形させたバネを楕円形に復元させることによって、バネの短手方向の一部分と他部分をスプリングリテナーの内溝に嵌め込んで、スプリングリテナーをガイド内に保持し、さらに、スプリングリテナーをガイド内より取り外すには、ガイドの鍔部に取り付けた押しピンを押圧して、楕円形のバネを円形に変形させることによって、楕円形のバネの短長手方向の一部分と他部分を、ガイドの鍔部の外溝に嵌め込み、バネの短手方向の一部分と他部分をスプリングリテナーの内溝に掛からないようにして、スプリングリテナーをガイド内より取り外し、以後、押しピンの押圧の解除と押しピンの押圧を繰り返して、スプリングリテナーとガイドとの着脱を行うことを特徴とする。 The present invention relates to a punching mold attaching / detaching mechanism constituted by a punch body, a ring-shaped spring retainer, a spring, a head, and a guide, and an inner groove is provided on the outer circumferential surface of the spring retainer, and About providing an outer groove on the inner circumferential surface, attaching a push pin to the outer circumferential surface of the guide collar, and fitting an elliptical spring into the inner groove of this spring retainer and the outer groove of the guide collar The elliptical spring has a part in the longitudinal direction fitted into the outer groove of the flange of the guide to which the push pin is attached, and the other part in the longitudinal direction of the elliptical spring is attached to the guide on the opposite side to which the push pin is attached. The spring retainer is guided by fitting it into the outer groove of the flange part and by inserting one part and the other part of the elliptical spring into the inner groove of the spring retainer. In order to insert the spring retainer into the guide, press the push pin attached to the collar of the guide, and deform the elliptical spring into a circular shape. Insert the elliptical spring in the short longitudinal part and the other part into the outer groove of the guide collar, so that the spring short part and the other part are not hooked in the inner groove of the spring retainer. Is inserted into the guide, and then the push pin is released and the circularly deformed spring is restored to an elliptical shape so that one part of the spring in the short direction and the other part fit into the inner groove of the spring retainer. In order to hold the spring retainer in the guide and remove the spring retainer from inside the guide, press the push pin attached to the collar of the guide, By deforming the screw into a circular shape, a part of the elliptical spring in the short longitudinal direction and the other part are fitted into the outer groove of the guide collar, and a part of the spring in the short direction and the other part are inserted into the inner groove of the spring retainer The spring retainer is removed from the guide so that the spring retainer is not hooked, and thereafter, the release of the push pin and the push pin are repeatedly pressed, and the spring retainer and the guide are attached and detached.

また、本発明は、前述したパンチング金型の着脱機構において、ガイドの鍔部に取り付けた押しピンとして、その側面に差込溝を設け、この差込溝に挿入バーを装填してに押しピンを確実、安全に保持することに特徴がある。 Further, according to the present invention, in the above-described punching die attaching / detaching mechanism, an insertion groove is provided on the side surface of the push pin attached to the flange portion of the guide, and an insertion bar is loaded into the insertion groove.

本発明によると、従来のように、Ｏリングを変形させるという大きな力を必要とせずに、簡単な操作で、作業効率よく、パンチング金型のガイドとスプリングリテナーの着脱を行うことが可能であり、特に、ガイドの溝をスプリングリテナーのＯリングより外す際に、ガイドとスプリングリテナーの間にドライバー等の工具を差し込むような余計な作業を行うことなく、ガイドやスプリングリテナーを損傷せずに、ガイドをスプリングリテナーから取り外すことができる利点がある。   According to the present invention, it is possible to attach and detach the punching die guide and the spring retainer with a simple operation and high work efficiency without requiring a large force for deforming the O-ring as in the prior art. Especially, when removing the guide groove from the O-ring of the spring retainer, without extra work such as inserting a screwdriver or other tool between the guide and the spring retainer, without damaging the guide and spring retainer, There is an advantage that the guide can be removed from the spring retainer.

本発明のパンチング金型の着脱機構の一例を、図に従って説明すると、パンチボディ１、リング状のスプリングリテナー２、スプリング３、ヘッド４、ガイド５とによって構成されることは、前述した図１と図２に示した従来のパンチング金型と同じであるが、従来のパンチング金型と異なる構成は、図３〜図６に示すように、スプリングリテナー２の外側円周面に内溝７を設け、また、ガイド５の鍔部の内側円周面に外溝１０を設けるとともにガイド５の鍔部の外側円周面に押しピン９を取り付け、さらに、楕円形のバネ８を内溝７と外溝１０に取り付ける点である。 An example of the attaching / detaching mechanism of the punching mold according to the present invention will be described with reference to the drawings. The punching body 1, the ring-shaped spring retainer 2, the spring 3, the head 4, and the guide 5 are configured as shown in FIG. 2 is the same as the conventional punching mold shown in FIG. 2, but is different from the conventional punching mold in that an inner groove 7 is provided on the outer circumferential surface of the spring retainer 2 as shown in FIGS. In addition, an outer groove 10 is provided on the inner circumferential surface of the collar portion of the guide 5, a push pin 9 is attached to the outer circumferential surface of the collar portion of the guide 5, and an elliptical spring 8 is connected to the inner groove 7 and the outer circumferential surface. It is a point attached to the groove 10.

スプリングリテナー２の内溝７とガイド５の鍔部の外溝１０に楕円形のバネ８を嵌め込むについては、図３に示すように、楕円形のバネ８の長手方向の一部分８Ｌａを、押しピン９を取り付けたガイド５の鍔部の外溝１０に嵌め込むとともに、楕円形のバネ８の長手方向の他部分８Ｌｂを、押しピン９を取り付けたガイド５の反対側のガイド５の鍔部の外溝１０に嵌め込み、かつ、図４に示すように、楕円形のバネの短手方向の一部分８Ｌａと他部分８Ｌｂを、スプリングリテナー２の内溝７に嵌め込んで、スプリングリテナー２をガイド５内に挿着する準備状態を形成する。 In order to fit the elliptical spring 8 into the inner groove 7 of the spring retainer 2 and the outer groove 10 of the flange of the guide 5, as shown in FIG. 3, the longitudinal portion 8La of the elliptical spring 8 is pushed. The other part 8Lb in the longitudinal direction of the elliptical spring 8 is fitted into the outer groove 10 of the collar part of the guide 5 to which the pin 9 is attached, and the collar part of the guide 5 opposite to the guide 5 to which the push pin 9 is attached. 4 and a part 8La and another part 8Lb of the elliptical spring in the short direction are fitted into the inner groove 7 of the spring retainer 2 to guide the spring retainer 2 as shown in FIG. 5 ready for insertion.

次いで、スプリングリテナー２をガイド５内に挿着するについては、ガイド５の鍔部に取り付けた押しピン８を指で押圧して、楕円形のバネ８を弾性に抗して円形に変形させることによって、楕円形のバネの短長手方向の一部分８Ｌａと他部分８Ｌｂを、ガイド５の鍔部の外溝１０に嵌め込んで、スプリングリテナー２の内溝７に掛からない状態にして、スプリングリテナー２をガイド５内に挿入した後、押しピン８の押圧を解除して、円形に変形させたバネ８を弾性によって楕円形に復元させることによって、バネの短手方向の一部分８Ｌａと他部分８Ｌｂをスプリングリテナー２の内溝７に嵌め込んで、スプリングリテナー２をガイド５内に保持する。 Next, for inserting the spring retainer 2 into the guide 5, the push pin 8 attached to the collar portion of the guide 5 is pressed with a finger to deform the elliptic spring 8 into a circular shape against elasticity. Thus, the short-longitudinal portion 8La and the other portion 8Lb of the elliptical spring are fitted into the outer groove 10 of the flange portion of the guide 5 so as not to be hooked on the inner groove 7 of the spring retainer 2, so that the spring retainer 2 Is inserted into the guide 5 and then the pressing of the push pin 8 is released, and the spring 8 deformed into a circular shape is restored to an elliptical shape by elasticity, so that the portion 8La and the other portion 8Lb in the short direction of the spring are The spring retainer 2 is held in the guide 5 by being fitted into the inner groove 7 of the spring retainer 2.

スプリングリテナー２をガイド５内より取り外すには、図５と図６に示すように、ガイド５の鍔部に取り付けた押しピン９を指で押圧して、楕円形のバネ８の弾性に抗して円形に変形させることによって、楕円形のバネの短手方向の一部分８Ｌａと他部分８Ｌｂを、ガイド５の鍔部の外溝１０に嵌め込み、スプリングリテナー２の内溝７に掛からないようにして、スプリングリテナー２をガイド５内より取り外す。 To remove the spring retainer 2 from the guide 5, as shown in FIGS. 5 and 6, the push pin 9 attached to the collar portion of the guide 5 is pressed with a finger to resist the elasticity of the elliptical spring 8. By deforming it into a circular shape, a part 8La and another part 8Lb in the short direction of the elliptical spring are fitted into the outer groove 10 of the collar part of the guide 5 so as not to be hooked on the inner groove 7 of the spring retainer 2. The spring retainer 2 is removed from the guide 5.

すなわち、楕円形のバネ８の長手方向の径はガイド５の鍔部の外溝１０の径より若干短くし、また、楕円形のバネ８の短手方向の径はスプリングリテナー２の内溝７の径より若干短くする必要があり、図７に示すように、指で押しピン９を押圧して楕円形のバネ８を弾性に抗して円形に変形、拡張して、楕円形のバネの短手方向の一部分８Ｌａと他部分８Ｌｂを、スプリングリテナー２の内溝７より外して、ガイド５の鍔部の外溝１０に嵌め込むことによって、スプリングリテナー２をガイド５内より取り外すことが可能になり、また、指を外して押しピン９による押圧を解除すると、図８に示すように、弾性によって楕円形のバネ８に復元、収縮して、楕円形のバネの短手方向の一部分８Ｌａと他部分８Ｌｂを、ガイド５の鍔部の外溝１０より外して、スプリングリテナー２の内溝７に嵌め込むことによって、スプリングリテナー２をガイド５内に取り付けることが可能になる。 That is, the diameter of the elliptic spring 8 in the longitudinal direction is slightly shorter than the diameter of the outer groove 10 of the flange portion of the guide 5, and the diameter of the elliptic spring 8 in the short direction is the inner groove 7 of the spring retainer 2. As shown in FIG. 7, the push pin 9 is pressed with a finger to deform and expand the elliptical spring 8 into a circular shape against elasticity, as shown in FIG. It is possible to remove the spring retainer 2 from the guide 5 by removing the portion 8La and the other portion 8Lb in the short direction from the inner groove 7 of the spring retainer 2 and fitting them in the outer groove 10 of the flange portion of the guide 5. When the finger is removed and the pressing by the push pin 9 is released, as shown in FIG. 8, the elastic spring restores and contracts to the elliptical spring 8, and the elliptical spring has a portion 8La in the short direction. And the other portion 8Lb, the outer groove 10 of the flange portion of the guide 5 Disconnect Te, by fitting the inner groove 7 of the spring retainer 2, it is possible to mount the spring retainer 2 into the guide 5.

以後は、前述した指による押しピン８の押圧と押圧の解除とを繰り返して、スプリングリテナー２とガイド５との着脱を行えばよいが、押しピン８の押圧と押圧の解除操作を、より確実、安全に行う必要がある場合には、図９に示すように、押しピン８の側面に差込溝１１を設け、この摺動溝１１にガイド５に付設した挿入バー１２を差し込むことによって、押しピン８をガイド５より抜け落ちし難くした状態で押しピン８の押圧と押圧の解除を確実、安全に行うようにしてもかまわない。
てもよい。 Thereafter, it is sufficient to repeat the pressing of the push pin 8 and the release of the pressing by the finger to attach and detach the spring retainer 2 and the guide 5. However, the pressing operation of the push pin 8 and the releasing operation of the pressing can be more reliably performed. When it is necessary to perform it safely, as shown in FIG. 9, an insertion groove 11 is provided on the side surface of the push pin 8, and an insertion bar 12 attached to the guide 5 is inserted into the sliding groove 11. The pressing of the push pin 8 and the release of the press may be surely and safely performed in a state where the push pin 8 is difficult to come off from the guide 5.
May be.

ガイド５の鍔部の外側円周面に取り付けた押しピン９の代わりに、図１０に示すように、回転カム１３を設けて、指で回転カム１３を９０度回転させることによって、押しピン８の押圧と押圧の解除を簡易に行うようにしてもよい。 Instead of the push pin 9 attached to the outer circumferential surface of the collar portion of the guide 5, as shown in FIG. 10, a rotary cam 13 is provided, and the rotary cam 13 is rotated 90 degrees with a finger, whereby the push pin 8 The pressing and release of the pressing may be performed simply.
