Description

本発明はプレス金型用ストリッピング装置に係り、より詳しくはプレス金型におけるパンチを用いた打孔作業において打孔後のパンチの後退移動時、前記パンチとパネルを分離させることにより、パネルが付いて上がることを防止するストリッピング装置の構造を改善することにより、作業の生産性及び効率性を向上させるように発明したものである。 The present invention relates to a stripping device for a press die, and more specifically, in a punching operation using a punch in a press die, when the punch moves backward after punching, the panel can be separated from the punch. It was invented to improve the productivity and efficiency of work by improving the structure of the stripping device that prevents it from sticking up.

一般に、金型用カムユニットはプレス金型に装着されて垂直往復運動の作業方向を変えて角度運動することができるようにしたもので、図1のように、ボックス型のカムベース1の底面には前後方向にスライド移動可能なカムスライダー3が装着され、カムスライダー3にはリターンスプリング5を挿入することができるスプリング孔6が形成され、下部にはカムドライバー7が取り付けられる。 Generally, the cam unit for a mold is attached to a press mold so that it can move in an angle by changing the working direction of vertical reciprocating motion. As shown in FIG. 1, it is mounted on the bottom surface of a box-shaped cam base 1. Is equipped with a cam slider 3 that can slide in the front-rear direction, a spring hole 6 into which a return spring 5 can be inserted is formed in the cam slider 3, and a cam driver 7 is attached to the lower portion.

前記のように構成されたカムユニットの作動過程は、図2のように、カムベース1全体が下降するにつれて、カムスライダー3の底面のスライド溝8がカムドライバー7の上面のスライド板9に沿ってガイド移動すれば、リターンスプリング5は弾性的に圧縮され、カムスライダー3が前進して、パンチ16がジグ14に固定装着されたパネルをパンチングするように構成されている。 In the operation process of the cam unit configured as described above, as shown in FIG. 2, as the entire cam base 1 is lowered, the slide groove 8 on the bottom surface of the cam slider 3 is along the slide plate 9 on the top surface of the cam driver 7. When the guide moves, the return spring 5 is elastically compressed, the cam slider 3 advances, and the punch 16 is configured to punch a panel fixedly mounted on the jig 14.

しかし、前述した従来のカムユニットは、リターンスプリングの弾性復帰力のみによってパネル製品にパンチング作業を完了したパンチを反対方向に復帰させるように構成されているため、最近に引張強度が増加した高張力鋼板のようなパネル及び厚さの大きなパネルにおいては前記パンチとパネル間の摩擦抵抗が大きくなって復帰移動に問題が生じる場合が頻繁であって高速打抜きができないかカムスライダー又はパンチが破壊される問題点があった。 However, since the conventional cam unit described above is configured to return the punch that has completed the punching work to the panel product in the opposite direction only by the elastic return force of the return spring, the high tension has recently increased. In panels such as steel plates and large panels, the frictional resistance between the punch and the panel often increases, causing problems in return movement, and high-speed punching is not possible or the cam slider or punch is destroyed. There was a problem.

したがって、前記問題点を解消するために、カムスライダーを復帰移動させるリターンスプリングの弾性を増大させて使っているが、前記高弾性スプリングの装着及び固定が難しく、カムユニットの作動中に前記高弾性力によって分離されて安全事故が発生する弊端があった。 Therefore, in order to solve the above problem, the elasticity of the return spring that returns and moves the cam slider is increased and used, but it is difficult to attach and fix the high elasticity spring, and the high elasticity is achieved during the operation of the cam unit. There was a problem that a safety accident occurred because it was separated by force.

また、前記リターンスプリングの弾性が高い状態では、カムスライダーがカムドライバーに最初に接触する衝突瞬間に前方に移動しなければならないが、前記リターンスプリングの弾性によってスムーズに前方に移動することができなくて衝撃力が増加し、その後、カムドライバーの前進移動時にも接触面間の垂直面圧が増加して接触面の摩耗進行が加速してカム装置の寿命を縮める問題点があった。 Further, when the elasticity of the return spring is high, the cam slider must move forward at the moment of collision when the cam slider first contacts the cam driver, but the elasticity of the return spring makes it impossible to move forward smoothly. As a result, the impact force increases, and then the vertical surface pressure between the contact surfaces increases even when the cam driver moves forward, which accelerates the progress of wear on the contact surfaces and shortens the life of the cam device.

前記のような従来技術の問題点を解決するためのもので、本発明は、打孔作業後にパンチとパネルをより簡便に分離させることができるようにするとともに前記カムスライダーの前面にパンチホルダー及びパンチが装着固定された状態でもパネルを押圧する押圧部材を入れ替えることができるようにすることにその目的がある。 In order to solve the above-mentioned problems of the prior art, the present invention makes it possible to more easily separate the punch and the panel after the punching operation, and also has a punch holder and a punch holder on the front surface of the cam slider. The purpose is to make it possible to replace the pressing member that presses the panel even when the punch is mounted and fixed.

本発明の他の目的は、ディスクスプリングを適用して積層構造の安全性を確保しながらも、パネルの種類によって前記ディスクスプリングの積層構造及び個数を調整することにより、カムスライダーの復帰移動が円滑になされ、パンチ作業の効率性を向上させることができるようにすることにある。 Another object of the present invention is to apply a disc spring to ensure the safety of the laminated structure, and to adjust the laminated structure and the number of the disc springs according to the type of the panel so that the cam slider can be smoothly returned and moved. It is done so that the efficiency of punching work can be improved.

本発明のさらに他の目的は、現存のパンチホルダーに直接装着することができ、内部に収容される押圧部材の装着及び分解が簡便であって組立工程及び使用の便宜性を向上させることができ、パンチ作業中に摩耗した押圧部材の入れ替えを速かに行って製品生産の効率性を高めるようにすることにある。 Still another object of the present invention is that it can be directly mounted on an existing punch holder, and the pressing member housed therein can be easily mounted and disassembled to improve the convenience of the assembly process and use. The purpose is to quickly replace the pressing member worn during the punching operation to improve the efficiency of product production.

本発明によるプレス金型用ストリッピング装置は、プレス金型におけるパンチを用いた打孔作業において、打孔後のパンチの後退移動時、前記パンチとパネルを分離させることにより、パネルが付いて上がることを防止するストリッピング装置の構造を改善することにより、作業の生産性及び効率性を向上させるように発明したものである。 The stripping device for a press die according to the present invention attaches and raises a panel by separating the punch and the panel when the punch moves backward after the punch in the punching operation using the punch in the press die. It was invented to improve the productivity and efficiency of work by improving the structure of the stripping device that prevents this.

以下、本発明によるストリッピング装置の構成を添付図面に基づいて詳細に記述する実施例によってその特徴を理解することができるであろう。 Hereinafter, the characteristics of the stripping apparatus according to the present invention can be understood by an example in which the configuration is described in detail based on the accompanying drawings.

まず、本発明で説明するストリッピング装置100はプレス金型用カムスライダー3の前方にパンチ16を含むパンチホルダー10に装着されるもので、ハウジング30の内部に弾性部材50及び押圧部材70を備え、パンチング作業中にパネルPに前記押圧部材70が接触して後方に押されるにつれて弾性部材50は弾性復元力を蓄積しながら圧縮され、パンチング作業を完了してカムスライダー3が後退すれば、前記弾性部材50の弾性復元力によって押圧部材70を前方に押し出すことにより、前記押圧部材70と接触したパネルPがパンチ16に付いて上がることを防止する構成を有する。 First, the stripping device 100 described in the present invention is mounted on a punch holder 10 including a punch 16 in front of the press mold cam slider 3, and includes an elastic member 50 and a pressing member 70 inside the housing 30. As the pressing member 70 comes into contact with the panel P and is pushed backward during the punching operation, the elastic member 50 is compressed while accumulating elastic restoring force, and when the punching operation is completed and the cam slider 3 retracts, the said By pushing the pressing member 70 forward by the elastic restoring force of the elastic member 50, the panel P in contact with the pressing member 70 is prevented from sticking to the punch 16 and rising.

このために、本発明によるストリッピング装置100は、まず円筒状のハウジング30の内部に可動板40、弾性部材50及び固定板60を順に挿入した後、前記固定板60が挿入された位置のハウジング30の先端を押し込んで互いに結束させる。 For this purpose, the stripping device 100 according to the present invention first inserts the movable plate 40, the elastic member 50, and the fixing plate 60 into the cylindrical housing 30 in order, and then the housing at the position where the fixing plate 60 is inserted. Push in the tips of 30 to bind them together.

これを図3〜図5に基づいて詳細に説明すれば、ハウジング30は、円筒状の内周面に押圧部材移動部31及び弾性部材収容部35が図面上の一側上部から他側下部側に連続的に形成され、他側の外周面には固定ホール39aを備えた支持部39が突設され、前記カムスライダー3の前面に固定ボルトを介して締結されて結合される。 Explaining this in detail with reference to FIGS. 3 to 5, in the housing 30, the pressing member moving portion 31 and the elastic member accommodating portion 35 are arranged on the cylindrical inner peripheral surface from the upper side on one side to the lower side on the other side on the drawing. A support portion 39 having a fixing hole 39a is projected from the outer peripheral surface on the other side, and is fastened to the front surface of the cam slider 3 via a fixing bolt to be connected.

ここで、前記ハウジング30の押圧部材移動部31は弾性部材収容部35より小さな大きさを持って連結されることによって前記連結部は段面を有することになるので、前記弾性部材収容部35に挿入される可動板40が前記段面にかかって移動が阻止される。 Here, since the pressing member moving portion 31 of the housing 30 is connected with a size smaller than that of the elastic member accommodating portion 35, the connecting portion has a stepped surface, so that the elastic member accommodating portion 35 has a stepped surface. The movable plate 40 to be inserted is applied to the step surface to prevent movement.

すなわち、前記可動板40は弾性部材収容部35と同じ外形を有し、中央にはパンチ16の通過する孔が形成され、ハウジング30の他側から弾性部材収容部35に挿入され、押圧部材移動部31に連結された段面にかかれて支持される。 That is, the movable plate 40 has the same outer shape as the elastic member accommodating portion 35, a hole through which the punch 16 passes is formed in the center, and the movable plate 40 is inserted into the elastic member accommodating portion 35 from the other side of the housing 30 to move the pressing member. It is supported by being hung on a step surface connected to the portion 31.

そして、弾性部材50は、前記弾性部材収容部35と同じ外形を有し、中央にはパンチ16が通過する孔が形成された皿形ディスクスプリングを適用し、前記ディスクスプリングが互いに対向する積層構造に挿入することが好ましい。 The elastic member 50 has the same outer shape as the elastic member accommodating portion 35, and a dish-shaped disc spring having a hole through which the punch 16 passes is applied to the center thereof, and the disc springs face each other in a laminated structure. It is preferable to insert it in.

ここで、前記皿形ディスクスプリングが積層して挿入される過程にも前記可動板40に接触する先端のディスクスプリングは図4のように可動板40の縁部を支持することで、前記弾性部材収容部35に沿ってスライドする可動板40を安定的に支えるようにする。 Here, even in the process in which the dish-shaped disc springs are laminated and inserted, the disc spring at the tip that comes into contact with the movable plate 40 supports the edge portion of the movable plate 40 as shown in FIG. The movable plate 40 that slides along the accommodating portion 35 is stably supported.

前記固定板60は前記弾性部材収容部35の内径より大きいな外径を有するように形成され、中央にパンチ16が通過する孔を備え、前記弾性部材収容部35の内周面に締まりばめ方式で挿入されるとともに前記ハウジング30の他側先端が押し込まれることによってハウジングに一体に結束される。 The fixing plate 60 is formed so as to have an outer diameter larger than the inner diameter of the elastic member housing portion 35, has a hole through which the punch 16 passes in the center, and is fastened to the inner peripheral surface of the elastic member housing portion 35. It is integrally bound to the housing by being inserted by a method and pushing the other end of the housing 30.

ここで、前記可動板40、弾性部材50及び固定板60の中央に形成された孔(符号なし)はパンチ16の移動を干渉せずに単純に通過可能にする孔であり、これについての説明は省略する。 Here, the hole (unsigned) formed in the center of the movable plate 40, the elastic member 50, and the fixed plate 60 is a hole that allows the punch 16 to simply pass through without interfering with the movement, and the description thereof will be described. Is omitted.

そして、固定板60がハウジング30に押し入れられて一体に結束される一実施例を説明すれば、まず弾性部材収容部35の他側先端に固定板挿合溝36を段差状に成形し、固定板60を押し入れて装着する。ここで、固定板60の外周面は弾性部材収容部35に挿入される一側より他側の直径が小さい傾斜面61を有するように成形する。 Then, to explain one embodiment in which the fixing plate 60 is pushed into the housing 30 and integrally bound, first, the fixing plate insertion groove 36 is formed in a stepped shape at the other end of the elastic member accommodating portion 35 and fixed. The plate 60 is pushed in and attached. Here, the outer peripheral surface of the fixing plate 60 is formed so as to have an inclined surface 61 having a diameter smaller than that of one side inserted into the elastic member accommodating portion 35.

すなわち、図4を参照すると、前記弾性部材収容部35に挿入される、一側から他側方向に小さく成形された傾斜面61を有する固定板60を前記固定板挿合溝36に押し入れるとともに前記傾斜面61が押し入れられるハウジング30の一側端を押し込むことにより、固定板挿合溝36の内周面に傾斜面61がかかって一体に結束される。 That is, referring to FIG. 4, the fixing plate 60 having the inclined surface 61 formed small from one side to the other side, which is inserted into the elastic member housing portion 35, is pushed into the fixing plate insertion groove 36. By pushing one side end of the housing 30 into which the inclined surface 61 is pushed in, the inclined surface 61 is applied to the inner peripheral surface of the fixing plate insertion groove 36 and is integrally bound.

また、固定板60がハウジング30に押し入れられて一体に結束される他の実施例を説明すれば、図6のように、弾性部材収容部35の他側先端の内周面に断面凹形の固定板挿合溝37を形成し、固定板60の外周面に前記固定板挿合溝37に対応する断面凸形の固定板挿合突条62を形成し、前記固定板60を弾性部材収容部35の内側に締まりばめ方式で押し入れて互いに結束させるものも本発明に含まれる。 Further, to explain another embodiment in which the fixing plate 60 is pushed into the housing 30 and integrally bound, as shown in FIG. 6, the elastic member accommodating portion 35 has a concave cross section on the inner peripheral surface of the other end of the elastic member accommodating portion 35. A fixed plate insertion groove 37 is formed, a fixed plate insertion ridge 62 having a convex cross section corresponding to the fixed plate insertion groove 37 is formed on the outer peripheral surface of the fixed plate 60, and the fixed plate 60 is accommodated as an elastic member. The present invention also includes one that is pushed into the inside of the portion 35 by a tightening method to bind each other.

そして、前記弾性部材収容部35は、固定板挿合溝37の先端部が外側に広がっているように加工した後、前記固定板60を挿入して固定板挿合溝37に固定板挿合突条62を位置させ、前記ハウジング30の一側を押し込んで凹凸結合させることによって一体に結束することが好ましい。 Then, the elastic member housing portion 35 is processed so that the tip portion of the fixing plate insertion groove 37 extends outward, and then the fixing plate 60 is inserted and the fixing plate is inserted into the fixing plate insertion groove 37. It is preferable that the ridges 62 are positioned and one side of the housing 30 is pushed in to form a concavo-convex bond so as to be integrally bound.

ここで、前記固定板挿合溝37及び固定板挿合突条62は断面“U”形又は断面“V”形のように多様に成形することができる。ハウジング30の弾性部材収容部35に可動板40及び弾性部材50が収納された状態でハウジング30に固定板60を押し入れてから端部を押し込むことによって一体に構成することにより、収納された可動板40及び弾性部材50が分離されないようにすることが重要である。 Here, the fixing plate insertion groove 37 and the fixing plate insertion ridge 62 can be formed in various ways such as a cross section "U" shape or a cross section "V" shape. The movable plate 40 and the elastic member 50 are housed in the elastic member accommodating portion 35 of the housing 30, and the fixed plate 60 is pushed into the housing 30 and then the end portion is pushed into the housing 30 to integrally configure the movable plate. It is important that the 40 and the elastic member 50 are not separated.

前記のように、ハウジング30の弾性部材収容部35に可動板40及び弾性部材50が挿入され、固定板60によって支持された状態で、前記弾性部材収容部35と連通する押圧部材移動部31に沿ってスライド移動可能に押圧部材70を挿入した後、前記押圧部材移動部31の先端に固定リング80を装着させることによって押圧部材70が分離されることを防止する。 As described above, the movable plate 40 and the elastic member 50 are inserted into the elastic member accommodating portion 35 of the housing 30, and in a state of being supported by the fixing plate 60, the pressing member moving portion 31 communicating with the elastic member accommodating portion 35. After inserting the pressing member 70 so as to be slidable along the line, the fixing ring 80 is attached to the tip of the pressing member moving portion 31 to prevent the pressing member 70 from being separated.

前記押圧部材70は、中央にパンチ16が移動する長手方向へのピン貫通ホール73が成形され、ハウジング30の一側から押圧部材移動部31にスライド移動可能に挿入されて前記可動板40と当接するガイド部71と、前記ガイド部71より小さな直径を有する突出部72とが一体に成形される。前記突出部72は押圧部材移動部31より外側に突出するように形成される。 The pressing member 70 has a pin penetration hole 73 formed in the center in which the punch 16 moves in the longitudinal direction, and is slidably inserted into the pressing member moving portion 31 from one side of the housing 30 to hit the movable plate 40. The contacting guide portion 71 and the protruding portion 72 having a diameter smaller than that of the guide portion 71 are integrally formed. The protruding portion 72 is formed so as to protrude outward from the pressing member moving portion 31.

すなわち、ハウジング30の押圧部材移動部31に押圧部材70のガイド部71が挿入されて可動板40に支持された初期状態で、前記押圧部材70が離脱することを防止するために、ガイド部71の前方位置の前記押圧部材移動部31の内周面にリング挿合溝32を形成し、前記ガイド部71の外径より小さな内径を有する固定リング80を前記リング挿合溝32に着脱可能に結合することで、前記押圧部材70のガイド部71が固定リング80にかかることにより、ガイド部71が一側方向に分離されることを防止することができる。 That is, in order to prevent the pressing member 70 from coming off in the initial state in which the guide portion 71 of the pressing member 70 is inserted into the pressing member moving portion 31 of the housing 30 and supported by the movable plate 40, the guide portion 71 A ring insertion groove 32 is formed on the inner peripheral surface of the pressing member moving portion 31 at a position in front of the guide portion 71, and a fixing ring 80 having an inner diameter smaller than the outer diameter of the guide portion 71 can be attached to and detached from the ring insertion groove 32. By connecting, the guide portion 71 of the pressing member 70 is engaged with the fixing ring 80, so that the guide portion 71 can be prevented from being separated in one side direction.

そして、ハウジング30の押圧部材移動部31には回転防止面33が突設され、前記押圧部材移動部31の内面に沿ってスライド移動する押圧部材70のガイド部71には前記回転防止面33に対応する回転阻止面71aが成形されることにより、前記押圧部材70が挿入された状態ではスライド移動のみ可能である。 A rotation prevention surface 33 is projected from the pressing member moving portion 31 of the housing 30, and the rotation prevention surface 33 is provided on the guide portion 71 of the pressing member 70 that slides and moves along the inner surface of the pressing member moving portion 31. By forming the corresponding rotation blocking surface 71a, only sliding movement is possible in the state where the pressing member 70 is inserted.

また、前記押圧部材移動部31を備えたハウジング30の外側面には前記リング挿合溝32と連通する工具挿入溝34がさらに形成され、前記工具挿入溝34を通して工具を挿入して、リング挿合溝32に装着された固定リング80を持ち上げることで固定リングを簡便に分離させることができる。 Further, a tool insertion groove 34 communicating with the ring insertion groove 32 is further formed on the outer surface of the housing 30 provided with the pressing member moving portion 31, and a tool is inserted through the tool insertion groove 34 to insert the ring. The fixing ring 80 can be easily separated by lifting the fixing ring 80 mounted on the joint groove 32.

また、前記固定リング80はこの実施例で断面円形に成形されているが、図6のように、一般的なスナップリング81を使うこともできる。この場合、スナップリング81の形状に対応するように断面方形のリング挿合溝32が成形される。 Further, although the fixing ring 80 is formed into a circular cross section in this embodiment, a general snap ring 81 can also be used as shown in FIG. In this case, the ring insertion groove 32 having a square cross section is formed so as to correspond to the shape of the snap ring 81.

このように構成された本発明によるストリッピング装置100の実施例を添付図4及び図5に基づいて説明すれば、まずパンチ16を備えたパンチホルダー10にハウジング30の支持部39を、固定ボルトを固定ホール39aを通してパンチホルダー10に締結することによって結合させる。 An embodiment of the stripping device 100 according to the present invention configured as described above will be described with reference to FIGS. 4 and 5. First, the support portion 39 of the housing 30 is attached to the punch holder 10 provided with the punch 16 by fixing bolts. Is fastened to the punch holder 10 through the fixing hole 39a.

ここで、前記パンチ16はハウジング30の固定板60、弾性部材50、可動板40を貫通して押圧部材70のピン貫通ホール73の内部に位置し、パンチング作業のためにパンチホルダー10が前方に移動すれば、パネルPに前記押圧部材70の突出部72が先に接触する。 Here, the punch 16 penetrates the fixing plate 60, the elastic member 50, and the movable plate 40 of the housing 30 and is located inside the pin penetration hole 73 of the pressing member 70, and the punch holder 10 is moved forward for punching work. If it moves, the protruding portion 72 of the pressing member 70 comes into contact with the panel P first.

そして、前記パンチホルダー10がさらに前方に移動すれば、押圧部材70の突出部72がパネルPによって押されて後方に移動するにつれて、押圧部材70が可動板40を押圧し、弾性部材50は弾性復元力を蓄積しながら圧縮され、ピン貫通ホール73の内部に位置するパンチ16は外部に突出してパネルPにパンチング作業を行う。 Then, when the punch holder 10 moves further forward, the pressing member 70 presses the movable plate 40 as the protruding portion 72 of the pressing member 70 is pushed by the panel P and moves backward, and the elastic member 50 is elastic. The punch 16 is compressed while accumulating the restoring force, and the punch 16 located inside the pin through hole 73 protrudes to the outside to perform a punching operation on the panel P.

その後、パンチング作業が完了した状態では、前記カムスライダー3に結合されたパンチホルダー10及びハウジング30が後退して初期状態に移動するにつれて、圧縮状態の弾性部材50が押圧部材70を前方に押し出すことになる。 After that, when the punching work is completed, the elastic member 50 in the compressed state pushes the pressing member 70 forward as the punch holder 10 and the housing 30 coupled to the cam slider 3 retract and move to the initial state. become.

すなわち、前記弾性部材50の弾性力によって可動板40が前方に移動しながら押圧部材70のガイド部71をスライド移動させ、前記押圧部材70は固定リング80にガイド部71がかかられて移動が阻止される。 That is, the elastic force of the elastic member 50 causes the movable plate 40 to slide forward while the guide portion 71 of the pressing member 70 is slid, and the pressing member 70 is moved by the guide portion 71 being hung on the fixing ring 80. Be blocked.

したがって、前記パンチング作業後のカムスライダー3の後退移動時、パンチ16との摩擦などによって付いて上がるパネルPを前記押圧部材70が前方に押し出すことによってパネルを安定的に分離させることができる。 Therefore, when the cam slider 3 is moved backward after the punching operation, the pressing member 70 pushes the panel P that rises due to friction with the punch 16 or the like forward, so that the panel can be stably separated.

そして、前記のようにパネルに接触する押圧部材70は、パネルの損傷を防止するために、パネルに比べて軟質の金属材から突出部72を成形する。長期間パンチング作業を行えば前記突出部72が摩耗するから、新しい押圧部材70に入れ替えなければならない。 Then, the pressing member 70 that comes into contact with the panel as described above forms the protruding portion 72 from a metal material that is softer than the panel in order to prevent damage to the panel. If the punching operation is performed for a long period of time, the protruding portion 72 will be worn, and therefore it must be replaced with a new pressing member 70.

前記入れ替え作業のためには、まずカムスライダー3を後退移動させてハウジング30の前方に押圧部材70の突出部72が突出するようにした後、別途の工具を用いてリング挿合溝32に装着された固定リング80を分離させる。 For the replacement work, the cam slider 3 is first moved backward so that the protruding portion 72 of the pressing member 70 protrudes in front of the housing 30, and then the cam slider 3 is mounted in the ring insertion groove 32 using a separate tool. The fixed ring 80 is separated.

これにより、押圧部材70のガイド部71は押圧部材移動部31に沿って前方にスライド移動してハウジング30から分離され、新しい押圧部材70のガイド部71を前記押圧部材移動部31に沿って挿入した後、リング挿合溝32に固定リング80を装着することで入れ替え作業を簡便に完了する。 As a result, the guide portion 71 of the pressing member 70 slides forward along the pressing member moving portion 31 and is separated from the housing 30, and the guide portion 71 of the new pressing member 70 is inserted along the pressing member moving portion 31. After that, the fixing ring 80 is attached to the ring insertion groove 32 to easily complete the replacement work.

以上のように、上述した実施例は本発明の最良の実施形態について説明したものであるが、前記実施例のみに限定されるものではなく、本発明の技術思想を逸脱しない範疇内で多様な変形が可能であるのは当業者に明らかなものである。
As described above, the above-described examples have described the best embodiments of the present invention, but are not limited to the above-mentioned examples, and are various within the scope of the technical idea of the present invention. It is obvious to those skilled in the art that the transformation is possible.
