Description

本発明は、パンチャーに関し、従来のピアスパンチとストリッパーとをユニット化し、その上、コンパクトにしたものである。 The present invention relates to a puncher, in which a conventional piercing punch and stripper are unitized and further compacted.

従来のピアス加工は、図９に示すようにして行っていた。下型基板１０１に固着したワーク支持部材１０２上にワークＷを載置し、ワークＷを押圧するパッド１０３を上型基板１０４に設けた吊りボルト１０５により吊り下げ、パッド１０３と上型基板１０４との間に縮設したコイルスプリング１０６によりパッド１０３を下方に向けて付勢し、ワークＷを押圧させる。ピアスパンチ１０７は上型基板１０４下面にリテーナー１０８により垂下状に固着する。 Conventional piercing has been performed as shown in FIG. A workpiece W is placed on a workpiece support member 102 fixed to the lower mold substrate 101, and a pad 103 that presses the workpiece W is suspended by a suspension bolt 105 provided on the upper mold substrate 104. The pad 103, the upper mold substrate 104, The pad 103 is urged downward by a coil spring 106 contracted between the two and the workpiece W is pressed. The piercing punch 107 is fixed to the lower surface of the upper mold substrate 104 in a hanging shape by the retainer 108.

ピアス加工は、ワーク支持部材１０２上にワークＷを載置し、上型１０９を下降させる。すると、まず最初にパッド１０３がワークＷを押圧し、下降し続けるとピアスパンチ１０７によりワークＷに孔開けをし、さらに下降して図９に示す下死点の状態となる。 In the piercing process, the workpiece W is placed on the workpiece support member 102 and the upper mold 109 is lowered. Then, first, the pad 103 presses the workpiece W, and when it continues to descend, the workpiece W is punched by the piercing punch 107, and further descends to the bottom dead center state shown in FIG.

孔開けが完了して上型１０９が上昇すると、パッド１０３はコイルスプリング１０６により下方に向けて付勢されているので、孔開けしてピアスパンチ１０７に付着しているワークＷをピアスパンチ１０７から抜き離す。 When the drilling is completed and the upper die 109 is raised, the pad 103 is biased downward by the coil spring 106, so that the workpiece W attached to the piercing punch 107 by drilling is removed from the piercing punch 107. Pull out.

パッド１０３は、ピアスパンチ１０７により孔開けを可能にするため、ピアスパンチ１０７による孔開け前にワークＷを安定させるために押圧させる。また、パッド１０３は、ピアスパンチ１０７による孔開け後は、ワークＷをピアスパンチ１０７から引き離す機能を有する。
特許第３０６９０８３号公報 The pad 103 is pressed in order to stabilize the workpiece W before the piercing punch 107 makes a hole so that the piercing punch 107 can make a hole. The pad 103 has a function of pulling the workpiece W away from the piercing punch 107 after the piercing punch 107 has opened the hole.
Japanese Patent No. 3069083

従来は、ピアス加工する際、ワークのピアス加工される箇所は小面積部分であるのに対し、ワークを押圧し、ワークをピアスパンチから引き離すパッドは大きなブロック体で、通常鋳物で製作する。パッドが大きなブロック体でその重量も大きく、機械加工する部分も多く、高価なプレス型となる。図９の図示例ではピアス加工する部分は平面の例を示しているが、通常は三次元の曲面であって、パッドは高価な倣い加工により形成される。 Conventionally, when piercing is performed, a portion of a workpiece to be pierced is a small area portion, whereas a pad that presses the workpiece and separates the workpiece from the piercing punch is a large block body, and is usually manufactured by casting. The pad is a large block body, its weight is large, and there are many parts to be machined, resulting in an expensive press die. In the illustrated example of FIG. 9, the pierced portion is an example of a plane, but is usually a three-dimensional curved surface, and the pad is formed by expensive copying.

また、ピアスパンチの規格化は進んでいるが、ピアス関連部品の規格化は行われておらず、設計、製造、生産管理の効率化が遅れている。 Moreover, although the standardization of piercing punches is progressing, the standardization of piercing-related parts has not been performed, and the efficiency of design, manufacturing, and production management has been delayed.

さらに、プレス加工では、図８に示すようなワークの側面にピアス加工するとき等に受動カム、作動カム等のカムが使用され、カム関連部品の規格化は既に行われ、設計、製造、生産管理の効率化が図られているが、カム関連部品規格とピアス関連部品の規格との関連づけは行われていない。 Furthermore, in press working, cams such as passive cams and actuating cams are used when piercing the side of the workpiece as shown in Fig. 8, and standardization of cam-related parts has already been carried out. Management efficiency has been improved, but the cam-related part standard and the pierce-related part standard are not related.

さらにその上に、より一層のコンパクト化したパンチャーが求められ、また、隣接する複数個の孔を１個のパンチャーで加工できることが求められている。 Furthermore, there is a demand for a more compact puncher, and it is also required that a plurality of adjacent holes can be processed with a single puncher.

本発明は、上記の事情に鑑み、下記の目的のために、開発された。 The present invention was developed for the following purposes in view of the above circumstances.

(1) ピアス加工の際、大きなパッドをなくして、ピアス加工に必要な必要最小限の箇所だけをワークを押圧するようにして、機械加工する部分を可及的に少なくして安価にピアス型の提供ができるようにする。 (1) When piercing, a large pad is eliminated, and the workpiece is pressed only at the minimum necessary parts for piercing, and the piercing type is made inexpensively with as few parts as possible to be machined. To be able to provide

(2) ピアス関連部品の規格化を行い、設計、製造、生産管理の効率化を図る。 (2) Standardize piercing-related parts to improve design, manufacturing, and production management efficiency.

(3) カム関連部品の規格化は既に行われているが、カム関連部品規格とピアス関連部品規格とを関連づける。即ち、例えば、直径１０ｍｍのピアスパンチを指定すれば、側面ピアス加工の際は、それに使用する受動カムや作動カム等のカム関連部品を指定できるようにして、より一層の設計、製造、生産管理の効率化を図る。 (3) Although standardization of cam-related parts has already been carried out, link the cam-related part standard with the piercing-related part standard. That is, for example, if a piercing punch with a diameter of 10 mm is specified, it is possible to specify cam-related parts such as a passive cam and an operating cam used for side piercing, thereby further designing, manufacturing and production management. To improve efficiency.

(4) より一層のコンパクト化したパンチャーとし、隣接する複数個の孔を１個のパンチャーで加工可能とする。 (4) The puncher is made more compact, and a plurality of adjacent holes can be processed with one puncher.

本発明は、ピアスパンチと、ピアスパンチを保持すると共に回り止め形状に形成されたパンチリテーナーと、ピアスパンチを覆いピアスパンチ先端部を突出させ、その内方にパンチリテーナーの全体を収容するカバーと、ピアスパンチに外嵌まりし、ピアスパンチによるワークの孔開け前にワークを押圧し、孔開け後ピアスパンチをワークより抜き、カバー内に収容され進退し、後端に停止フランジを形成したストリッパーと、カバー内に収容されたストリッパーの停止フランジに当接し、ストリッパーを外方向に向けて付勢すると共に収容室に収容されたコイルスプリングとよりなり、カバーの収納室の上部を縮径させてストリッパーの外周と対向するカバーの上壁を形成し且つ上壁をその下方に連なると共にコイルスプリングの外周と対向する収納室の壁よりも肉厚に形成し、カバー下端の外周面の一部に延設した取付部に穿設した取付孔に対して取付ボルトを挿通して基板又はスライドカムに形成されたネジ孔に螺着されることを特徴とするパンチャーとした。 The present invention relates to a piercing punch, a punch retainer that holds the piercing punch and has a non-rotating shape, a cover that covers the piercing punch, protrudes the tip of the piercing punch, and accommodates the entire punch retainer inside thereof. Stripper that fits outside the piercing punch, presses the workpiece before drilling the workpiece with the piercing punch, pulls out the piercing punch from the workpiece after drilling, moves forward and backward in the cover, and forms a stop flange at the rear end And a contact with a stop flange of the stripper housed in the cover, urging the stripper outward and a coil spring housed in the housing chamber, and reducing the upper diameter of the cover housing chamber. The upper wall of the cover that faces the outer periphery of the stripper is formed and the upper wall is connected to the lower side of the cover, and is also paired with the outer periphery of the coil spring. The wall is formed thicker than the wall of the storage chamber, and the mounting bolt is inserted into the mounting hole drilled in the mounting portion extending to a part of the outer peripheral surface of the lower end of the cover, and formed on the substrate or the slide cam The puncher was characterized by being screwed into the screw hole.

さらに、本発明は、ピアスパンチが複数個であるパンチャーとした。 Furthermore, the present invention is a puncher having a plurality of piercing punches.

本発明は、上述の構成により、上記目的の(1) (2) (3) (4) を達成できる。 The present invention can achieve the above objects (1), (2), (3), and (4) by the above-described configuration.

本発明を添付する図面に示す具体的実施例に基づいて、以下詳細に説明する。 The present invention will be described in detail below based on specific embodiments shown in the accompanying drawings.

図１は本発明のパンチャーを装着したピアス型の上死点状態の正面断面図、図２は図１のピアス型の下死点の状態の正面断面図である。 FIG. 1 is a front sectional view of a pierced top dead center state equipped with a puncher of the present invention, and FIG. 2 is a front sectional view of a pierced bottom dead center state of FIG.

下型基板４１に固着したワーク支持部材４２上にワークＷを載置し、ワークＷにピアス加工するパンチャー４３を上型基板４４に固着する。 A workpiece W is placed on the workpiece support member 42 fixed to the lower mold substrate 41, and a puncher 43 for piercing the workpiece W is fixed to the upper mold substrate 44.

ピアス加工は、ワーク支持部材４２上にワークＷを載置し、上型４５を下降させると、まず最初にストリッパー５がワークＷを押圧し、下降し続けるとピアスパンチ１によりワークＷに孔開けをし、さらに下降して図２に示す下死点状態となる。 In the piercing process, when the workpiece W is placed on the workpiece support member 42 and the upper die 45 is lowered, the stripper 5 first presses the workpiece W, and when it continues to descend, the workpiece W is punched by the piercing punch 1. And further descend to the bottom dead center state shown in FIG.

孔開けが完了して上型４５が上昇すると、ストリッパー５はコイルスプリング６により下方に向けて付勢されているので、孔開けしてピアスパンチ１に付着しているワークＷをピアスパンチ１から引き離す。 When the punching is completed and the upper die 45 is raised, the stripper 5 is urged downward by the coil spring 6, so that the workpiece W attached to the piercing punch 1 after drilling is removed from the piercing punch 1. Pull apart.

ストリッパー５は、ピアスパンチ１により孔開けを可能にするため、ピアスパンチ１による孔開け前にワークＷを安定させるために押圧させる。また、ストリッパー５は、ピアスパンチ１による孔開け後は、ワークＷをピアスパンチ１から引き離す機能を有する。 The stripper 5 is pressed to stabilize the workpiece W before the piercing punch 1 makes a hole so that the piercing punch 1 can make a hole. The stripper 5 has a function of pulling the workpiece W away from the piercing punch 1 after the piercing punch 1 has made a hole.

図３は、本発明のパンチャーの具体的実施例の組立正面図、図４は図３の平面図である。 FIG. 3 is an assembly front view of a specific embodiment of the puncher of the present invention, and FIG. 4 is a plan view of FIG.

本発明のパンチャーは、ピアスパンチ１と、ピアスパンチ１を保持するパンチリテーナー２と、ピアスパンチ１を覆いピアスパンチ１先端部を突出させ、パンチリテーナー２を収容するカバー３と、ピアスパンチ１に外嵌まりし、ピアスパンチ１によるワークＷの孔開け前にワークＷを押圧し、孔開け後ピアスパンチ１をワークＷより抜き、カバー３内に収容され、進退し、後端に停止フランジ４を形成したストリッパー５と、カバー３内に収容されストリッパー５を停止フランジ４に当接し、ストリッパー５を外方に向けて付勢するコイルスプリング６とよりなる。ピアスパンチ１を起立させたパンチリテーナ２は、カバー３内に収容し、先端を段部５４に当接させ、その外周は非円形の回り止め形状に形成し、その底面は支持板５１で覆い、支持板５１はボルト５２によりカバー３に螺締する。 The puncher of the present invention includes a piercing punch 1, a punch retainer 2 that holds the piercing punch 1, a cover 3 that covers the piercing punch 1 and projects the tip of the piercing punch 1, and a piercing punch 1. It fits outside, presses the workpiece W before drilling the workpiece W by the piercing punch 1, and after drilling, the piercing punch 1 is pulled out of the workpiece W, accommodated in the cover 3, moves forward and backward, and stops at the rear end with the stop flange 4 And a coil spring 6 housed in the cover 3 and abutting the stripper 5 against the stop flange 4 and urging the stripper 5 outward. The punch retainer 2 in which the piercing punch 1 is erected is accommodated in the cover 3, the tip is brought into contact with the stepped portion 54, the outer periphery thereof is formed in a non-circular detent shape, and the bottom surface is covered with the support plate 51. The support plate 51 is screwed to the cover 3 with bolts 52.

パンチリテーナー２は、カバー３外に露出させているものに比して本発明ではカバー３内に全て収容されているので、パンチャーとしてより一層コンパクト化される。 Since the punch retainer 2 is entirely accommodated in the cover 3 in the present invention as compared with the one exposed outside the cover 3, the punch retainer 2 can be made more compact as a puncher.

ピアスパンチ１は工具鋼で焼入れ研磨されたもので、パンチリテーナー２に保持される。パンチリテーナー２は保持孔７を穿設し、保持孔７にピアスパンチ１を圧入起立させる。ピアスパンチ１基端の係合フランジ８は拡径穴９内に位置させる。このパンチリテーナー２は、ピアスパンチとストリッパーをコンパクト化するためにカバー３内に収容する。カバー３には、コイルスプリング６を収容できる収容室１４を形成し、収容室１４の上壁１５にはストリッパー５の回り止めをなす楕円孔１６を穿設する。カバー３下端の外周面の一部に延設した取付部１３の中央部には取付ボルト１８を挿通させる取付孔１９を穿設し、取付ボルト１８を取付孔１９に通し、下型４５の基板４４のネジ孔２３に螺着する。
また、カバー３の収納室１４の上部を縮径させてストリッパー５の外周と対向するカバー３の上壁１５によって囲まれた小径室を形成しており、上壁１５は、その下方に連なる壁（即ちコイルスプリング６の外周と対向する収納室１４の壁）よりも肉厚に形成されている。 The piercing punch 1 is hardened and polished with tool steel and is held by a punch retainer 2. The punch retainer 2 has a holding hole 7, and press-fits the piercing punch 1 into the holding hole 7. The engagement flange 8 at the base end of the piercing punch 1 is positioned in the enlarged diameter hole 9. This punch retainer 2 is accommodated in the cover 3 in order to make the piercing punch and stripper compact. The cover 3 is formed with a storage chamber 14 in which the coil spring 6 can be stored, and an upper wall 15 of the storage chamber 14 is provided with an elliptical hole 16 that prevents the stripper 5 from rotating. A mounting hole 19 through which the mounting bolt 18 is inserted is formed in the central portion of the mounting portion 13 extending to a part of the outer peripheral surface of the lower end of the cover 3, the mounting bolt 18 is passed through the mounting hole 19, and the substrate of the lower mold 45 44 is screwed into the screw hole 23.
The upper portion of the storage chamber 14 of the cover 3 is reduced in diameter to form a small-diameter chamber surrounded by the upper wall 15 of the cover 3 facing the outer periphery of the stripper 5, and the upper wall 15 is a wall continuous below the upper wall 15. That is, it is formed thicker than the wall of the storage chamber 14 facing the outer periphery of the coil spring 6.

ストリッパー５は、ピアスパンチ１に外嵌まりし、ピアスパンチ１によるワークＷの孔開け前にワークＷを押圧し、孔開け後ピアスパンチ１をワークＷより抜き、カバー３内に収容され進退し、後端に停止フランジ４を形成する。 The stripper 5 is externally fitted to the piercing punch 1 and presses the workpiece W before drilling the workpiece W by the piercing punch 1, and after piercing, the piercing punch 1 is removed from the workpiece W and is housed in the cover 3 and moves forward and backward. The stop flange 4 is formed at the rear end.

ストリッパー５は、前記カバー３の収容室１４に収容して後端の停止フランジ４を上壁１５に係合させてカバー３より前方に突出させる。カバー３の収容室１４内に縮設して収容したコイルスプリング６の上端を停止フランジ４に当接させてストリッパー５を外方に向けて付勢する。ピアスパンチ１でワークＷに孔開けする前にワークＷをストリッパー５の先端面１７で押圧し、上型４５が下降すると、ストリッパー５はカバー３の収容室１４内に進入し、その停止フランジ４によりコイルスプリング６を圧縮する。ストリッパー５の先端面１７がピアスパンチ１の先端面２０と一致し、上型４５が下降すると、ピアスパンチ１はワークに孔開けを行う。上型４５がなおも下降すると、ピアスパンチ１はワークに突入する。上型４５が上昇しだすと、ストリッパー５はコイルスプリング６により外方に向けて付勢されているので、ワークＷをピアスパンチ１から抜き離す。カバー３の収容室１４は、ストリッパー５にワークＷの孔開け前の押圧力に必要なストローク、孔開け後にワークＷをピアスパンチ１から抜き離す、抜き離し力に必要なストロークを与えるように設定する。 The stripper 5 is accommodated in the accommodating chamber 14 of the cover 3 and the stop flange 4 at the rear end is engaged with the upper wall 15 so as to protrude forward from the cover 3. The upper end of the coil spring 6 accommodated in the accommodating chamber 14 of the cover 3 is brought into contact with the stop flange 4 and the stripper 5 is urged outward. Before the work W is pressed by the tip end surface 17 of the stripper 5 before the work W is punched by the piercing punch 1 and the upper die 45 is lowered, the stripper 5 enters the housing chamber 14 of the cover 3 and its stop flange 4 Thus, the coil spring 6 is compressed. When the front end surface 17 of the stripper 5 coincides with the front end surface 20 of the piercing punch 1 and the upper die 45 is lowered, the piercing punch 1 punches a workpiece. When the upper die 45 is still lowered, the piercing punch 1 enters the workpiece. When the upper die 45 starts to rise, the stripper 5 is urged outward by the coil spring 6, so that the workpiece W is pulled away from the piercing punch 1. The storage chamber 14 of the cover 3 is set so as to give the stripper 5 a stroke necessary for the pressing force before the workpiece W is drilled, and a stroke necessary for removing the workpiece W from the piercing punch 1 after drilling. To do.

ピアスパンチが丸孔以外の四角等の非円形の孔開けするには、ピアスパンチの回り止めが必要となるが、ストリッパー５を楕円径外周面２１に形成して、前記カバー３の楕円孔１６と嵌合させる。 In order for the pierce punch to open a non-circular hole such as a square other than the round hole, it is necessary to prevent the pierce punch from rotating. However, the stripper 5 is formed on the outer peripheral surface 21 of the elliptical diameter, and the elliptical hole 16 of the cover 3 is formed. And fit.

ピアス加工する際は、当初は，ピアスパンチ１の先端面１７はストリッパー５内に没入しているが、上型４５が下降してワークＷに当接すると、ピアスパンチ１はカバー３の収容室１４内に進入して行きピアスパンチ１はコイルスプリング６により外方に向けて付勢され、ストリッパー５によりワークＷを付勢し、ピアスパンチ１によりワークＷへの孔開け前にワークＷを安定させる。ピアスパンチ１によりワークＷへの孔開け後、上型４５が上昇すると、ストリッパー５はコイルスプリング６で付勢されているのでワークＷからピアスパンチ１を抜き離す。 At the time of piercing, the tip surface 17 of the piercing punch 1 is initially immersed in the stripper 5, but when the upper die 45 descends and comes into contact with the workpiece W, the piercing punch 1 is accommodated in the housing chamber of the cover 3. The piercing punch 1 enters the inside 14 and is biased outward by the coil spring 6, and the workpiece W is biased by the stripper 5, and the workpiece W is stabilized before piercing the workpiece W by the piercing punch 1. Let When the upper die 45 is lifted after making a hole in the workpiece W by the piercing punch 1, the stripper 5 is biased by the coil spring 6, so that the piercing punch 1 is pulled away from the workpiece W.

ワークが、図８に示すように、三次元曲面の際は、パンチャーを下型基板４１に取付けた後、ストリッパー５の先端面１７を倣い加工を行い、ワークの三次元曲面に十分に当接するようにする。 As shown in FIG. 8, when the workpiece is a three-dimensional curved surface, after attaching the puncher to the lower mold substrate 41, the tip surface 17 of the stripper 5 is copied to sufficiently contact the three-dimensional curved surface of the workpiece. Like that.

支持板５１を、図４に示すように、カバー３底面にボルト５２により螺締し、このパンチャーはカバー３の取付け部１３の中央の取付孔１９にボルト１８を挿入し、上型基板４４のネジ孔２３に螺締し、カバー３と上型基板４４とに２本のノックピン５３を打ち込んで正確に位置決めをする。 As shown in FIG. 4, the support plate 51 is screwed to the bottom surface of the cover 3 with a bolt 52, and this puncher inserts the bolt 18 into the center mounting hole 19 of the mounting portion 13 of the cover 3. The screw holes 23 are screwed, and two knock pins 53 are driven into the cover 3 and the upper mold substrate 44 for accurate positioning.

ピアスパンチ１の先端面２０は平面のままであり、傾斜角１０°までは十分にピアス加工ができる。 The tip surface 20 of the piercing punch 1 remains flat, and piercing can be sufficiently performed up to an inclination angle of 10 °.

隣接する複数個の孔を１個のパンチャーで加工する例を、図５〜図７に示す。本実施例では２個の孔を１個のパンチャーで加工する例である。図５がその底面図、図６が正面図、図７が側面図である。 Examples of processing a plurality of adjacent holes with one puncher are shown in FIGS. In this embodiment, two holes are processed with one puncher. 5 is a bottom view, FIG. 6 is a front view, and FIG. 7 is a side view.

１個のストリッパー５の両側に２個のピアスパンチ１を配置し、このストリッパー５はコイルスプリング６で付勢されてカバー３内に収容され、ピアスパンチ１はカバー３に収容されたリテーナー２に起立している。カバー３はその取付部１３の取付孔１９に挿通したボルト１８で、下型４５の基板４４に螺締し、カバー３はノックピン５３を打設して正確に位置決めする。 Two piercing punches 1 are arranged on both sides of one stripper 5, and the stripper 5 is energized by a coil spring 6 and accommodated in the cover 3. The piercing punch 1 is attached to a retainer 2 accommodated in the cover 3. Standing up.
