Description

本発明は、断面異形の金属線材の伸線加工に使用するダイス等の金属加工用の型の異形形状の孔を研磨する異形孔研磨装置に関するものである。   The present invention relates to a modified hole polishing apparatus for polishing a deformed hole of a metal processing mold such as a die used for wire drawing of a deformed metal wire rod.

金属線材の伸線加工に使用するダイス（線引きダイス）の内周面を研磨する方法としては、研磨治具の棒状の研磨部をダイスに挿入し、ダイスあるいは研磨治具を回転させることにより周方向に研磨位置を変えつつ研磨治具を上下運動させ、研磨部をダイスの内周面に押し当てて研磨するようにしたものが従来から知られている（例えば、特許文献１参照。）。しかし、このようにダイスあるいは研磨治具を回転させることにより周方向に研磨位置を変える方法で研磨できるダイスは、断面が丸形状の金属線材（いわゆる丸線）を伸線加工するのに使用する孔形状が円形のダイスであって、断面が四角その他の異形形状の金属線材（いわゆる異形線）の伸線加工に使用するダイス（いわゆる異形ダイス）の場合は、孔が異形形状であるため、ダイスあるいは研磨治具を回転させることはできない。そのため、異形ダイスの研磨は、従来、自動化できなくて、手作業で行うしかなく、例えば異形ダイスのアプローチ部を磨く場合には、アプローチ部と同じテーパー角度を持たせた同じ異形形状の研磨部を有する研磨治具をアプローチ部に挿入し、研磨剤（スラリー）を通して、手で研磨冶具をアプローチ部内面に押し付けて上下にこすりながら磨き、その磨く位置を周方法に順次移動させて全内周面を磨くといった方法で行っていた。
特開平７−２４７１９号公報 As a method of polishing the inner peripheral surface of a die (drawing die) used for wire drawing of a metal wire rod, a rod-shaped polishing portion of a polishing jig is inserted into the die and rotated by rotating the die or the polishing jig. 2. Description of the Related Art Conventionally, a polishing jig is moved up and down while changing a polishing position in a direction, and a polishing portion is pressed against an inner peripheral surface of a die for polishing (see, for example, Patent Document 1). However, the dies that can be polished by rotating the dies or the polishing jig to change the polishing position in the circumferential direction are used for drawing a metal wire having a round cross section (so-called round wire). In the case of a die (so-called deformed die) used for wire drawing of a metal wire rod having a circular shape or other deformed shape (so-called deformed wire), since the hole has a deformed shape, The die or polishing jig cannot be rotated. For this reason, the polishing of the odd-shaped dies has conventionally been impossible to automate and must be performed manually.For example, when polishing the approach portion of the odd-shaped die, the polishing portion of the same deformed shape having the same taper angle as the approach portion. Insert a polishing jig with a tip into the approach section, pass the polishing agent (slurry), press the polishing jig against the inner surface of the approach section by hand, polish it by rubbing up and down, and move the polishing position to the circumferential method in order to move the entire inner circumference. It was done by polishing the surface.

The die 2 is loaded with a side pressure, and the side pressure can be adjusted by adjusting the spring pressure of the compression spring 15.

また、装置本体テーブル１上には、ダイス取付板３の背後となる位置に昇降部フレーム１６が立設され、その昇降部フレーム１６の、ダイス取付板３に面する前面側の垂直な壁面に、一対の昇降用ガイドレール１７が固定されて、その一対の昇降用ガイドレール１７により昇降自在に研磨治具昇降板１８が保持されている。   An elevating part frame 16 is erected on the apparatus main body table 1 at a position behind the die attaching plate 3, and a vertical wall surface on the front side facing the die attaching plate 3 of the elevating part frame 16 is provided. A pair of elevating guide rails 17 is fixed, and a polishing jig elevating plate 18 is held by the pair of elevating guide rails 17 so as to be movable up and down.

そして、断面形状がダイス２のアプローチ部の立体形状と相似形でアプローチ部に挿入可能なテーパー状で断面異形の棒状の研磨部を有する研磨治具１９（ポンチ）を圧縮バネ２０で下方へ付勢した状態で垂直に保持するとともに研磨治具１９を上方から押圧駆動するよう主軸２１を保持する研磨治具保持板２２が、一対の引張バネ２３で引き上げ方向に弾性支持されて研磨治具昇降板１８の前面に配置され、研磨治具昇降板１８の前面に固定された一対の垂直なリニアガイド２４に沿って上下移動自在とされている。   Then, a polishing jig 19 (punch) having a rod-shaped polishing portion having a tapered cross-sectional shape that is similar to the three-dimensional shape of the approach portion of the die 2 and can be inserted into the approach portion is attached downward by a compression spring 20. A polishing jig holding plate 22 that holds the main shaft 21 so as to hold the main shaft 21 so as to press and drive the polishing jig 19 from above is elastically supported in a pulling direction by a pair of tension springs 23 and moves up and down the polishing jig. It is arranged on the front surface of the plate 18 and is movable up and down along a pair of vertical linear guides 24 fixed to the front surface of the polishing jig lifting plate 18.

また、研磨治具昇降板１８の背部には研磨治具昇降板１８の図示しない開口部を貫通して後方へ突出するよう駆動棒２５が固定され、駆動棒２５の後端にベアリング部２６が設けられ、研磨治具昇降板１８と一体に昇降移動するよう研磨治具駆駆動用のモータ２７が設置されて、そのモータ２７の出力軸先端に、駆動棒２５後端のベアリング部２６に当接する偏心カム２８が設けられている。   A driving rod 25 is fixed to the back portion of the polishing jig lifting plate 18 so as to pass through an opening (not shown) of the polishing jig lifting plate 18 and protrude rearward, and a bearing portion 26 is provided at the rear end of the driving rod 25. A motor 27 for driving the polishing jig is installed so as to move up and down integrally with the polishing jig lifting plate 18, and the motor 27 has a front end of the output shaft of the motor 27 and a bearing portion 26 at the rear end of the driving rod 25.

Yes.

この異形孔研磨装置は、図２に示すように、ダイス２（異形ダイス）に外部から側圧をかけてテーパー状の異形孔であるアプローチ部の内周面と研磨治具１９（ポンチ）の研磨部との間に押し付け力を作用させつつ、研磨剤を入れ、研磨治具１９を上下動させることによりアプローチ部の内周面を研磨する。そして、ダイス２に負荷する側圧の方向（側圧をかけてダイス２のアプローチ部の内周面を研磨治具１９の研磨部に押し付ける方向）を、タイミングプーリ１０を回転させることにより周方向に順次移動させ、ダイス２のアプローチ部の全内周面を研磨する。ダイス２は研磨治具１９に押し付けられていて回転しない。   As shown in FIG. 2, this irregular hole polishing apparatus polishes the inner peripheral surface of the approach portion which is a tapered irregular hole by applying lateral pressure to the die 2 (various die) from the outside and the polishing jig 19 (punch). While applying a pressing force to the part, an abrasive is put in and the polishing jig 19 is moved up and down to polish the inner peripheral surface of the approach part. Then, the direction of the side pressure applied to the die 2 (the direction in which the side pressure is applied and the inner peripheral surface of the approach portion of the die 2 is pressed against the polishing portion of the polishing jig 19) is sequentially turned in the circumferential direction by rotating the timing pulley 10. The entire inner peripheral surface of the approach portion of the die 2 is polished. The die 2 is pressed against the polishing jig 19 and does not rotate.
