Description

この発明は、工作機械や産業機械に使用されるワイパーに関するものである。   The present invention relates to a wiper used for machine tools and industrial machines.

工作機械による切削加工の際に発生する加工屑(以下、切粉)は、ワイパー等に直接衝突することがあり、ワイパー等の破損を招く重大な影響を与える。特に、ワイパーにおいては、リップ部に切粉が衝突すると、リップ部に損傷が発生し、掻き取り性能の低下を招くという重大な問題が生じる。   Machining scraps (hereinafter referred to as chips) generated during cutting with a machine tool may directly collide with a wiper or the like, and have a serious influence that causes damage to the wiper or the like. In particular, in the wiper, when the chips collide with the lip portion, the lip portion is damaged, which causes a serious problem that the scraping performance is lowered.

近年、上記問題を解決するため、わが社では、掻取部を含めたリップ部の大部分を帆布等の繊維材料で被覆した工作機械用ワイパーを開発した(例えば、特許文献1。)。この工作機械用ワイパーでは繊維材料の存在により、切粉の衝突によるリップ部の損傷が非常に軽減されると共に、被掻取面に対する高速摺動が可能になる。   In recent years, in order to solve the above problems, our company has developed a wiper for machine tools in which most of the lip portion including the scraping portion is covered with a fiber material such as canvas (for example, Patent Document 1). In this machine tool wiper, the presence of the fiber material greatly reduces the damage to the lip caused by the collision of chips, and enables high-speed sliding with respect to the scraped surface.

しかしながら、上記工作機械用ワイパーでは、使用時間の経過に伴って掻取部のゴム部分が摩耗してくると、掻き取り部の被掻取面への接触部がゴム部分と帆布部分で形成されたものとなってしまう。したがって、リップ部を被掻取面に一定圧で押し付けてあっても、掻取部と被掻取部との接触圧は一部では大きく他部では小さくなってしまう。つまり、この工作機械用ワイパーでは、切粉の掻き取りはできるが、長期間安定したクーラントの掻き取りができないという事態を招く可能性がある。
特開2000−354934号公報
However, in the above machine tool wiper, when the rubber portion of the scraping portion wears with the passage of time of use, the contact portion of the scraping portion with the scraped surface is formed by the rubber portion and the canvas portion. It becomes a thing. Therefore, even if the lip portion is pressed against the surface to be scraped at a constant pressure, the contact pressure between the scraping portion and the scraping portion is large in some portions and small in other portions. In other words, with this machine tool wiper, chips can be scraped off, but there is a possibility that the coolant cannot be scraped stably for a long period of time.
JP 2000-354934 A

そこでこの発明では、工作機械や産業機械において、切粉の衝突によるリップ部の損傷が非常に軽減され且つ確実に長期間安定した切粉及びクーラントの掻き取りができるワイパーを提供することを課題とする。   In view of this, the present invention has an object to provide a wiper capable of scraping away chips and coolant that is extremely reduced in damage to the lip due to the collision of chips and reliably stable for a long period of time in machine tools and industrial machines.

図1はこの発明の実施例1における工作機械用ワイパーWの断面図、図2は図1のA部の拡大図を示している。
(この工作機械用ワイパーWの基本的構成について)
この工作機械用ワイパーWは、一般にスライドシールと呼ばれているものであり、図1や図2に示すように、基台表面やカバーの表面等のような掻取面9に対して相対的に往復移動する工作機械に取り付けられる取付部1と、前記取付部1に対して一体的に形成された弾性を有するリップ部2とから構成されており、前記リップ部2の掻取部20と被掻取面9との間に繊維材料3が形成されない態様で、飛散切粉が衝突するリップ部2部分に繊維材料3を被覆形成してある。なお、図1はこの工作機械用ワイパーWの断面形状を示すものであるが、当該工作機械用ワイパーWはその巾寸法がかなり大きいものである。
(工作機械用ワイパーWの各部構成について)
取付部1は、図1や図2に示すように芯金10と弾性部11と一体的に成形して成るものである。
FIG. 1 is a cross-sectional view of a machine tool wiper W according to Embodiment 1 of the present invention, and FIG. 2 is an enlarged view of portion A of FIG.
(Basic configuration of this machine tool wiper W)
The machine tool wiper W is generally called a slide seal, and is relative to a scraping surface 9 such as a base surface or a cover surface as shown in FIGS. A mounting portion 1 that is attached to a machine tool that reciprocates and a lip portion 2 having elasticity formed integrally with the mounting portion 1, and a scraping portion 20 of the lip portion 2. The fiber material 3 is coated on the lip portion 2 where the scattered chips collide with the scraped surface 9 so that the fiber material 3 is not formed between them. FIG. 1 shows a cross-sectional shape of the machine tool wiper W. The machine tool wiper W has a considerably large width.
(About the configuration of each part of machine tool wiper W)
As shown in FIGS. 1 and 2, the attachment portion 1 is formed by integrally molding a cored bar 10 and an elastic portion 11.

リップ部2は、図1や図2に示すように、被掻取面9と接する鋭角形状の掻取部20を有するものであり、前記掻取部20の先端は繊維材料3の下端部とはほぼ一致させるようにしてある。   As shown in FIGS. 1 and 2, the lip portion 2 has an acute-angled scraping portion 20 in contact with the surface 9 to be scraped, and the tip of the scraping portion 20 is connected to the lower end portion of the fiber material 3. Are almost matched.

ここで、上記弾性部11及びリップ部2は、NBR、ウレタンゴム、フッ素ゴム、H−NBR等から成形され、耐油性を有し且つ硬度が70度から90度(JIS A)の範囲内に設定してあるものが使用されている。   Here, the elastic part 11 and the lip part 2 are molded from NBR, urethane rubber, fluorine rubber, H-NBR, etc., and have oil resistance and hardness within a range of 70 to 90 degrees (JIS A). What is set is being used.

繊維材料3は、織布、編布等の帆布であり、これらは脂肪族ポリアミド、芳香族ポリアミド、ポリエステル等の合成繊維、天然繊維、ガラス繊維、比較的硬度の低い金属繊維等の一種又は二種以上を使用して構成させることができるが、繊維材料3は脂肪族ポリアミド、芳香族ポリアミド、ポリエステル等の合成繊維により構成された織布であることが好ましい。なお、繊維材料3は、そのまま使用してもよいがゴム含浸処理されたものでもよく、リップ部2に接着剤等を用いて積層接着したり、加硫接着によりリップ部2に一体化できる。
(この工作機械用ワイパーWの優れた機能について)
この工作機械用ワイパーWは、飛散切粉が衝突するリップ部2に繊維材料3を被覆形成してあるから、切粉の衝突によるリップ部の損傷が非常に軽減される。
The fiber material 3 is a canvas such as a woven fabric or a knitted fabric. These are one or two of synthetic fibers such as aliphatic polyamide, aromatic polyamide, and polyester, natural fibers, glass fibers, and metal fibers having relatively low hardness. The fiber material 3 is preferably a woven fabric composed of synthetic fibers such as aliphatic polyamide, aromatic polyamide, and polyester. The fiber material 3 may be used as it is or may be subjected to a rubber impregnation treatment, and can be laminated and bonded to the lip portion 2 using an adhesive or the like, or can be integrated with the lip portion 2 by vulcanization adhesion.
(About the excellent functions of this machine tool wiper W)
In the machine tool wiper W, the fiber material 3 is coated on the lip portion 2 where the scattered chips collide, so that damage to the lip portion due to the collision of the chips is greatly reduced.

また、リップ部2の掻取部20と被掻取面9との間に繊維材料3が形成されない態様としてあるから、時間の経過に関係なく、ゴム材料等で構成された掻取部20が被掻取面9に直接接触する状態が維持される。したがって、掻取部20の被掻取面9への接触圧が全域でほぼ均等である状態が維持されることになるから、確実に長期間安定した切粉及びクーラントの掻き取りができる。   Further, since the fiber material 3 is not formed between the scraping portion 20 of the lip portion 2 and the surface 9 to be scraped, the scraping portion 20 made of a rubber material or the like is used regardless of the passage of time. A state of directly contacting the scraped surface 9 is maintained. Therefore, the state in which the contact pressure of the scraping portion 20 on the surface to be scraped 9 is substantially uniform throughout the entire area is maintained, so that it is possible to reliably scrape off chips and coolant stably for a long period of time.

つまり、この工作機械用ワイパーWによると、工作機械や産業機械において、切粉の衝突によるリップ部の損傷が軽減され且つ確実に長期間安定した切粉及びクーラントの掻き取りができる。
(この工作機械用ワイパーWの製造方法の一例について)
金型内の適所に繊維材料3を配置して、金型内に未加硫ゴムを充填し、この未加硫ゴムを加硫して取付部1及びリップ部2を形成すると同時に繊維材料3をリップ部2等に加硫接着する。
That is, according to the machine tool wiper W, damage to the lip due to the collision of chips is reduced in the machine tool or industrial machine, and the chips and coolant can be scraped stably for a long period of time.
(About an example of the manufacturing method of this machine tool wiper W)
The fiber material 3 is placed at a proper position in the mold, and the mold is filled with unvulcanized rubber, and the unvulcanized rubber is vulcanized to form the attachment portion 1 and the lip portion 2 and at the same time the fiber material 3 Is vulcanized and bonded to the lip 2 or the like.

ここで、未加硫ゴムの一部が繊維材料3に含浸あるいは繊維材料3の目を通過した状態で加硫されるから、リップ部2等と繊維材料3とが一体となり接着強度が優れたものとなっている。   Here, since a part of the unvulcanized rubber is vulcanized in a state in which the fiber material 3 is impregnated or passed through the eyes of the fiber material 3, the lip portion 2 and the fiber material 3 are integrated and excellent in adhesive strength. It has become a thing.
