【発明の詳細な説明】
この発明はプレス型における上下型の摺動の為に用いる
ガイドピンとそれに嵌合するガイドホルダーにおいて、
ガイドホルダーの内径摺動面に固体潤滑剤を埋設して無
給油摺動可能とする為の固体潤滑剤の埋設方法に関する
もので、その目的は固体潤滑剤の潤滑特性をそこなうこ
となく、容易に埋設せしめんとする製造方法を得るにあ
る。Detailed Description of the Invention The present invention relates to a guide pin used for sliding the upper and lower molds in a press mold and a guide holder fitted thereto.
This relates to a method for embedding a solid lubricant in the inner diameter sliding surface of a guide holder to enable oil-free sliding. The purpose is to obtain a manufacturing method for embedding.
従来ガイドホルダーの内径摺動面に固体潤滑剤を埋設す
る為には、埋設溝に対して粉末状の固体潤滑剤を埋設す
る方法として加熱加圧方法があるが、これは加圧する為
の装置が膨大なものとなり、高価になってしまい、かつ
固体潤滑剤の埋設孔での保持性の点で劣っているという
欠点があった。Conventionally, in order to embed solid lubricant in the inner diameter sliding surface of a guide holder, there is a heating and pressurizing method to embed powdered solid lubricant in the embedding groove, but this method uses a device for applying pressure. The problem is that the amount of solid lubricant is large and expensive, and the solid lubricant is poorly retained in the buried hole.
また、固体潤滑剤をペースト状にして充てんしても固化
する前に流れ出てしまい、かつ気泡が入りやすくてコス
ト上、品質上欠点があった。Furthermore, even if a solid lubricant is filled in the form of a paste, it flows out before it solidifies, and air bubbles are likely to enter, resulting in disadvantages in terms of cost and quality.
本発明はこのような欠点をのぞき、埋設孔での固体潤滑
剤の保持性もよく、かつ気泡が入らず、安価にできると
いう方法を容易に得ることができる。The present invention overcomes these drawbacks and makes it possible to easily obtain a method that has good retention of the solid lubricant in the buried hole, does not contain air bubbles, and can be done at low cost.
本発明の製造方法について、ひとつの実施例を図面にも
とづいて説明すると、第１図においてガイドホルダー１
の内径摺動面２にらせん状溝３を旋盤加工によって切る
。One embodiment of the manufacturing method of the present invention will be explained based on the drawings. In Fig. 1, a guide holder 1
A spiral groove 3 is cut on the inner diameter sliding surface 2 by lathe processing.
この場合にこの溝はらせん状でゆでなく輪冠状又は複数
個の孔を機械加工その他鋳鍛造でつくってもよい。In this case, the groove may not be formed in a spiral shape, but may be formed in the form of an annular ring or a plurality of holes by machining or by casting or forging.
次に黒鉛を主成分として二硫化モリブデン、その他の種
々添加剤を加えて更にエポキシ樹脂をバインダーとして
加えて混合する。Next, molybdenum disulfide and various other additives are added to graphite as a main component, and an epoxy resin is further added as a binder and mixed.
こうしてできあがったペースト状固体潤滑剤４を第２図
の如くらせん状溝３にヘラ等を用いて充てんせしめる。The pasty solid lubricant 4 thus produced is filled into the spiral groove 3 using a spatula or the like as shown in FIG.
その後すぐにポリ四ふつ化エチレン製の棒体５をこの内
径摺動面に挿入する。Immediately thereafter, a rod 5 made of polytetrafluoroethylene is inserted into this inner diameter sliding surface.
この棒体５の外径はガイドホルダー１の内径よりもわず
かに細いものとする。The outer diameter of this rod 5 is slightly smaller than the inner diameter of the guide holder 1.
この棒体を入れることにより、らせん状溝３に充てんせ
しめた固体潤滑剤４は流出の恐れもない。By inserting this rod, there is no fear that the solid lubricant 4 filled in the spiral groove 3 will flow out.
これを乾燥炉に入れて加熱することにより固体潤潤滑を
固化せしめる。This is placed in a drying oven and heated to solidify the solid lubricant.
その後、棒体５を抜く。この場合に棒体５が他の鋼材類
であればバインダーとして用いたエポキシ樹脂によって
接着されてしまい抜けにくいが、ここでは棒体である為
に接着することなく容易にひき抜くことができる。After that, the rod 5 is removed. In this case, if the rod 5 were made of other steel, it would be adhered by the epoxy resin used as a binder and would be difficult to pull out, but here, since it is a rod, it can be easily pulled out without adhesion.
あとは摺動面の仕上げを施せばよいわけである。All that is left to do is to finish the sliding surfaces.
このようにして容易にガイドホルダーに固体潤滑剤を埋
設することができる。In this way, the solid lubricant can be easily embedded in the guide holder.

特徴とする無給油ガイドホルダーの製造法。1. In a guide holder that fits with a guide pin in a press mold, a spiral or ring-shaped groove with multiple holes is made on the inner diameter sliding surface by machining or casting and forging, and an epoxy resin containing graphite as a main component is applied thereto. After filling with a paste-like solid lubricant as a binder, a rod made of polytetrafluoroethylene is inserted and solidified by heating.
A method of manufacturing an oil-free guide holder characterized by removing the rod and then finishing the sliding surface again.
