一種電解修整裝置,包含用於軋製用的鋼輥的研磨加工的導電性的磨石、與磨石隔有間隙且相面向的電極及對磨石與電極供電的電極,於磨石與電極之間的間隙供給導電性的研磨液而將附著於研磨加工中的磨石的表面的鋼輥的研磨粉予以電解除去,其中電極的與磨石相面向的面以金屬製的薄板構成,與磨石相面向的面以外的部分以絕緣材料構成。An electrolytic dressing device includes a conductive grinding stone used for grinding a steel roller for rolling, an electrode facing the grinding stone with a gap therebetween, and an electrode for supplying power to the grinding stone and the electrode, wherein a conductive grinding fluid is supplied to the gap between the grinding stone and the electrode to electrolytically remove the grinding powder of the steel roller attached to the surface of the grinding stone during grinding, wherein the surface of the electrode facing the grinding stone is made of a metal thin plate, and the portion other than the surface facing the grinding stone is made of an insulating material.
Description
本發明係關於適用於軋製用的鋼輥的圓筒研磨之電解修整裝置及電解修整方法。 The present invention relates to an electrolytic dressing device and an electrolytic dressing method suitable for cylindrical grinding of steel rolls for rolling.
鋼製軋製輥有鑄鋼、工具鋼(模具鋼、高速鋼)等的種類。軋製熱的素材的熱軋製使素材被加熱而因高溫而軟化。熱軋製的目的是在高溫期間盡可能壓扁素材而降低板厚度。熱軋製中使用大尺徑的的鑄鋼輥。熱軋製後形成板或線圈的形狀,成為厚板製品。使熱軋製後的厚板製品形成為薄板或薄帶的製品的軋製為冷軋製。板或線圈已被冷卻而變成室溫。素材在室溫時比高溫時以高強度軋製所需的力更大。冷軋製所使用的輥以不遜於素材的強度的更高強度的鋼所製造。因此,被稱為模具鋼或高速鋼的高合金的工具鋼也被使用。藉由採用高合金,賦予輥高強度及強韌性,而能夠進行高強度材料的軋製。特別是高強度的不鏽鋼等的研磨帶鋼被用於彈簧等,可說是代表性的高硬度的材料。為了對此進行冷軋製,高合金的高速鋼輥係為合適,但是反覆冷軋製必須定期進行再研磨。然而,高速鋼具有高強度及強韌性,因而再研磨變成困難的加工製程。 Steel rolling rolls include cast steel, tool steel (die steel, high-speed steel), and other types. Hot rolling is the process of rolling hot materials by heating the materials and softening them due to the high temperature. The purpose of hot rolling is to flatten the materials as much as possible during the high temperature period to reduce the thickness of the plate. Large-diameter cast steel rolls are used in hot rolling. After hot rolling, the material is formed into the shape of a plate or coil, becoming a thick plate product. Cold rolling is the process of forming a thick plate product after hot rolling into a thin plate or thin strip product. The plate or coil has been cooled and has reached room temperature. The force required to roll the material at high strength at room temperature is greater than that at high temperature. The rolls used in cold rolling are made of steel with a higher strength than that of the material. Therefore, high alloy tool steels called die steel or high speed steel are also used. By using high alloys, high strength and toughness are given to the rollers, and high-strength materials can be rolled. In particular, high-strength stainless steel and other grinding belt steels are used for springs, etc., and can be said to be representative high-hardness materials. In order to cold-roll this, high-alloy high-speed steel rollers are suitable, but repeated cold rolling requires regular regrinding. However, high-speed steel has high strength and toughness, so regrinding becomes a difficult processing process.
當以鋼輥軋製板或帶的素材時,素材與輥接觸的面會殘留痕跡。若將此痕跡放著不管,則接續軋製的素材會發生形狀不良或瑕疵而變成缺陷。因此,輥須定期再研磨。然而,模具鋼及高速鋼具有高強度及強韌性,因而磨 石表面容易附著輥研磨粉而發生阻塞,研磨變得困難。因此,存在研磨一個輥需要長時間的課題。當研磨性差則研磨效率低下,結果也使板或帶的生產效率低落。特別是比模具鋼添加合金元素數及添加量更多的高速鋼,如同上述,素材本身常用於製造高強度的不鏽鋼的薄板及薄帶時的軋製。藉由高速鋼輥進行軋製,軋製後的板或帶的表面形狀良好,能夠得到美麗的外觀。但是,如同上述,高速鋼輥的研磨性差,因而與模具鋼相比被使用的頻率低,而成為高速鋼輥普及上的課題。軋製輥的再研磨的製程的改善,也與金屬的板、帶的製品的品質提升有關。 When a plate or strip material is rolled with a steel roller, traces will remain on the surface where the material contacts the roller. If these traces are left alone, the continuously rolled material will develop poor shape or defects and become defects. Therefore, the rollers must be regrinded regularly. However, mold steel and high-speed steel have high strength and toughness, so wear Roller grinding powder easily adheres to the stone surface and becomes clogged, making grinding difficult. Therefore, there is a problem that it takes a long time to grind one roller. When the grindability is poor, the grinding efficiency is low, and as a result, the production efficiency of the plate or belt is also low. In particular, high-speed steel has a higher number and amount of alloying elements than die steel. As mentioned above, the material itself is often used for rolling when producing high-strength stainless steel sheets and strips. By rolling with high-speed steel rollers, the surface shape of the rolled plate or strip is good, and a beautiful appearance can be obtained. However, as mentioned above, high-speed steel rollers have poor abrasiveness and are used less frequently than mold steels. This has become a problem in the popularization of high-speed steel rollers. The improvement of the regrinding process of rolling rolls is also related to the improvement of the quality of metal plates and strip products.
作為提升上述的研磨性的技術,存在有與研磨加工同時將磨石的表面予以電解修整的技術。習知的電解修整裝置的典型構成表示於圖7。再者,也存在有例如專利文獻1所記載的技術。專利文獻1所記載的研磨加工裝置包含:研磨加工工件的磨石、與磨石的研磨面隔有使研磨液介入的間隙且電極面相面向的電解修整用電極及對介入有研磨液的磨石及電解修整用電極通電的電源,用於將磨石的表面予以電解修整並研磨加工工件。然而,如專利文件1所記載的習知技術,是對磨石本身進行電解修整,而非藉由電解將附著於磨石的表面的研磨粉除去。 As a technique for improving the above-mentioned grindability, there is a technique of electrolytically dressing the surface of a grindstone simultaneously with the grinding process. The typical structure of a conventional electrolytic dressing device is shown in Figure 7 . Furthermore, there is also a technology described in Patent Document 1, for example. The grinding processing device described in Patent Document 1 includes a grinding stone for grinding a workpiece, an electrode for electrolytic dressing facing the grinding surface of the grinding stone with a gap for inserting abrasive fluid, and a grinding stone for inserting abrasive fluid. and a power supply that energizes the electrode for electrolytic dressing, which is used to electrolytically dress the surface of the grinding stone and grind the workpiece. However, the conventional technology described in Patent Document 1 performs electrolytic dressing on the grindstone itself, rather than removing abrasive powder adhered to the surface of the grindstone through electrolysis.
再者,如圖7所示的習知的電解修整裝置所採用的電極為金屬製的塊體,由於其重量之故而製作性、可搬運性及設置性差,也要高額的成本。 Furthermore, the electrode used in the conventional electrolytic dressing device shown in FIG. 7 is a metal block, which has poor manufacturability, transportability, and installation due to its weight, and also requires a high cost.

圖1係表示根據本發明的第一實施例的電解修整裝置100的構成的示意圖。電解修整裝置100包含磨石102、電極103及電源104。另外,元件符號101為軋製用的鋼輥。再者,元件符號105為研磨液供給來源(槽),元件符號106為吐出研磨液的噴嘴,係藉由管件(軟管)與研磨液供給來源(槽)連接。

磨石102為用於鋼輥101的研磨加工的圓柱狀的導電性的磨石,藉由被支承在圓筒研磨盤等的裝置的旋轉軸而被旋轉驅動。作為磨石102的接合材料,能夠應用既有的各種接合材料,但是金屬接合材料堅硬,與鋼輥相抵碰則會使鋼輥的表面產生如敲擊痕跡的缺陷。因此,作為磨石102的接合材料,以使樹脂接合材料含有金屬纖維而賦予通電性(導電性)的金屬樹脂接合材料為佳。作為磨石102的號數能夠應用既有的各種號數,但是本案申請人努力實驗的結果,得到了以#200至#4000的範圍,更限定以#400至#2000的範圍為佳的發現。另外,本說明書所記載的號數(粒度)是根據或以JIS R 6001-1:2017(磨石用研磨材料的粒度-第一部:粗粒)、JIS R 6001-2:2017(磨石用研磨材料的粒度-第二部:細粉)及在製造及販賣磨石的業界常用的表示方式為準。作為磨石102的磨粒可應用既有的各種種類,但是本案申請人努力實驗的結果,得到了以CBN為佳的見解。

電極103為用於將附著於磨石102的表面的鋼輥101的研磨粉予以電解除去的電極。電極103如圖所示為塊體狀,並具有剖面圓弧狀的電極面。此電極面為與磨石102的外周面相面向的長矩形,並以於與磨石102的外周面之間形成有容許導電性的研磨液的介入的例如約0.5mm至7.0mm的間隙的方式形成圓筒內周面狀。另外,圖1中表示電極103設置為並列於磨石102的旁邊的狀態,但是設置電極103的位置並不限定於此。
於此參照圖2A至圖2C並對電極103進一步說明。圖2A為電極103的前視圖,圖2B為電極103的側視圖,圖2C為電極103的A-A線剖面圖。如圖所示,電極103的與磨石102相面向的面亦即剖面圓弧狀的電極面係由金屬製的薄板201構成。再者,電極103的與磨石102相面向的面以外的部分以絕緣材料200構成。作為薄板201的具體的素材,能夠應用鈦、銅等各種的金屬。薄板201的寬度(圖2B中的橫方向的幅度)以與磨石102的寬度相同或以上為佳。作為絕緣
材料200的具體的材料,例如能夠應用氯乙烯、聚碳酸酯等的各種塑膠。藉由使電極103為上述構成,與整體以金屬構成的習知的電極相比,除了大幅地輕量化,也得到製作性、可搬運性及設置性的提升及成本的削減的效果。另外,雖然沒有特別限定電極面的大小,本案申請人努力實驗的結果,得到了電極面的周方向的長度,即薄板201的圓弧長超過磨石102的圓周長(外周長)的15%(亦即,周方向中薄板201包覆磨石102的比率超過15%)的場合能夠得到良好的效果的發現。
The
電源104為將根據研磨條件的適當的電壓及電流予以供給(供電)至磨石102及電極103的電源。作為電源104,能夠應用直流電源、直流脈衝電源、交流電源、雙極性增幅器等各種型式的電源。在本實施例中,透過供電線108(配線)對電極103(薄板201)供電,並且透過供電線109(配線)對磨石102供電。另外,對於磨石102,亦可藉由設置於供電線109的前端的電刷進行供電,但是若為藉由後述的供電用的配件107(軸承301)供電的型態,能夠更安定地供電。
The
接著,參照圖3A及圖3B並說明能夠對磨石102的安定的供電的配件107。圖3A為配件107的側視圖,圖3B為配件107的前視圖。如圖所示,配件107具有作為主要零件的軸承301,並且具有將軸承301收納於內部的軸套300。但是,亦可適當地省略軸套300。軸承301具有導電性(通電性),並以能夠通電的方式固定於磨石102的軸(旋轉軸)。對軸承301的導電性(通電性)的賦予,例如藉由於組裝軸承301時使用導電性(通電性)的油脂而實現。軸承301藉由供電線109(配線)固定於外環而與電源104電連接。供電線109(配線)固定於外環的方法沒有特別限定,能夠應用例如:於如元件符號302所示的孔插入供電線109(配線)並固定的方法,或者藉由軟焊而直接固定於外環的方法。藉由透過軸承301對磨石102供電的型態,與藉由伴隨著使用而消耗的電刷的供電相比,能夠進行安定的供電。再者,也得到廢棄零件的減少的效果。
Next, the
對如同以上說明的電解修整裝置100的動作進行說明。首先,相對用於鋼輥101的研磨加工的導電性的磨石102,以隔有容許導電性的研磨液的介入的間隙而相面向的方式固定電極103。接著,從噴嘴106供給研磨液至磨石102與電極103的間隙,藉由電源104對磨石102及電極103供電。藉此,附著於研磨加工中的磨石102的表面的鋼輥101的研磨粉被連續地電解除去(電解修整),能夠保持磨石102的磨粒與鋼輥101接觸的狀態,研磨性提升。另外,準備外環藉由供電線109(配線)與電源104電連接的導電性(通電性)的軸承301而以能夠通電的方式設置於磨石102的軸,只要透過軸承301從電源104對磨石102供電,則能夠安定地供電。
The operation of the
接著,對根據本發明的第二實施例的電解修整裝置400進行說明。
Next, the
圖4係表示根據本發明的第二實施例的電解修整裝置400的構成的示意圖。電解修整裝置400的包含:磨石102、電極401及電源104。鋼輥101、磨石102、電源104、研磨液供給來源105(槽)、配件107、供電線108(配線)及供電線109(配線)與第一實施例相同。
FIG4 is a schematic diagram showing the structure of an
電極401為用於將附著於磨石102的表面的鋼輥101的研磨粉予以電解除去的電極。電極401如圖所示為塊體狀,並具有剖面圓弧狀的電極面。此電極面為與磨石102的外周面相面向的長矩形,並以於與磨石102的外周面之間形成有容許導電性的研磨液的介入的例如約0.5mm至7.0mm的間隙的方式形成圓筒內周面狀。另外,圖4中表示電極401設置為並列於磨石102的旁邊的狀態,但是設置電極401的位置並不限定於此。
接著,參照圖5A至圖5C並對電極401進一步說明。圖5A為電極401的前視圖,圖5B為電極401的側視圖,圖5C為電極401的B-B線剖面圖。如圖所示,電極401的與磨石102相面向的面亦即剖面圓弧狀的電極面係由金屬製的薄板502構成。再者,電極401的與磨石102相面向的面以外的部分以絕緣材料500
構成。作為薄板502的具體的素材,能夠應用鈦、銅等各種的金屬。薄板502的寬度(圖5B中的橫方向的幅度)以與磨石102的寬度相同或以上為佳。作為絕緣材料500的具體的材料,例如能夠應用氯乙烯、聚碳酸酯等的各種塑膠。藉由使電極401為上述構成,與整體以金屬構成的習知的電極相比,除了大幅地輕量化,也得到製作性、可搬運性及設置性的提升及成本的削減的效果。另外,雖然沒有特別限定電極面的大小,本案申請人努力實驗的結果,得到了電極面的周方向的長度,即薄板502的圓弧長超過磨石102的圓周長(外周長)的15%(亦即,周方向中薄板502包覆磨石102的比率超過15%)的場合能夠得到良好的效果的見解。
Next, the
於此,電極401在內部504構成為中空、於絕緣材料500至少設置一個研磨液導入口501、以及於薄板502設置複數個微小的研磨液供給孔503的這些點上與根據第一實施例的電極103相異。研磨液導入口501為用於將研磨液導入電極401的內部504的開口,藉由管件(軟管)與研磨液供給來源(槽)連接。另外,電極401中,雖然研磨液導入口501設置於正面,但是亦可設置於背面等其他的面。藉由將電極401定為以上所述的構成,通過電極401的內部504及研磨液供給孔503,研磨液平均地供給至磨石102與電極401之間的間隙(研磨液供給步驟)。藉此,電極面中研磨液的流動的局部的不平均受到改善,能夠穩定保持磨石102的表面性質狀態。另外,將電極401設置於如圖4所示的位置時,能夠使越下方的研磨液供給孔503的孔徑越小(越上方的研磨液供給孔503的孔徑越大)。藉由使越下方的研磨液供給孔503的孔徑越小,能夠改善從下到上的研磨液的供給的不平均。
Here, the
再者,也能夠使電極401為圖5D所示的型態。亦即,能夠於電極401的內部504設置至少一個分割內部504的分隔壁505。藉由於電極401的內部504設置分隔壁505,除了能夠提高電極401的剛性,也能夠使藉由研磨液導入口
501導入的研磨液平衡良好地分布於電極401的內部504。再者,藉由分隔壁505使電極401的內部504分割成不同大小(容積)時,能夠在對應於藉由分隔壁505分割為大的內部504(504L)的研磨液供給孔503(503L)及對應於藉由分隔壁505分割為小的內部504(504S)的研磨液供給孔503(503S)使研磨液供給孔503的孔徑具有不同的大小。例如,能夠使對應於藉由分隔壁505分割為大的內部504(504L)的研磨液供給孔503(503L)為小孔徑,使對應於藉由分隔壁505分割為小的內部504(504S)的研磨液供給孔503(503S)為大孔徑。亦能夠相反。根據設置電極401的位置、方向、角度及研磨液的黏度等的條件,在對應於藉由分隔壁505分割為大的內部504(504L)的研磨液供給孔503(503L)及對應於藉由分隔壁505分割為小的內部504(504S)的研磨液供給孔503(503S)使研磨液供給孔503的孔徑具有不同的大小,藉此能夠改善對磨石102及電極401之間的間隙的研磨液的供給的不平均。
Furthermore, the
藉由如以上說明的根據本發明的第二實施例的電解修整裝置400,附著於研磨加工中的磨石102的表面的鋼輥101的研磨粉被連續地電解除去(電解修整),能夠保持磨石102的磨粒與鋼輥101接觸的狀態,研磨性提升。另外,與根據本發明的第一實施例的電解修整裝置100相同,準備外環藉由供電線109(配線)與電源104電連接的導電性(通電性)的軸承301而以能夠通電的方式設置於磨石102的軸,只要透過軸承301從電源104對磨石102供電,則能夠安定地供電。
By means of the
接著,對根據本發明的第三實施例的電解修整裝置600進行說明。
Next, the
圖6A係表示根據本發明的第三實施例的電解修整裝置600的構成的示意圖。電解修整裝置600包含:磨石102、電極401、電極601及電源104。電極401與第一實施例相同。再者,鋼輥101、磨石102、電源104、研磨液供給來源105(槽)及供電線108(配線)與第一實施例相同。
FIG. 6A is a schematic diagram showing the structure of an
電極401為用於將附著於磨石102的表面的鋼輥101的研磨粉予以電解除去的電極。電極401的構成與第二實施例相同。另外,圖6A中表示電極401設置為並列於磨石102的旁邊的狀態,但是設置電極401的位置並不限定於此。再者,在本實施例中,將根據第二實施例的電極401定為第一電極,但是,第一電極亦可為根據第一實施例的電極103。
The
電極601為具有與作為第一電極的電極401相同構成的電極(第二電極)。作為第二電極的電極601,於與作為第一電極的電極401相異的位置,以與磨石102隔有間隙且相面向的方式設置(第二電極設置步驟)。另外,圖6A中表示電極601設置於磨石102的鉛直下方的狀態,但是設置電極601的位置不限定於此。
The
根據本發明第三實施例的電解修整裝置600中,電源104透過供電線109(配線),取代磨石102,改為對電極601(第二電極)供電。
In the
藉由如以上說明的根據本發明的第三實施例的電解修整裝置600,附著於研磨加工中的磨石102的表面的鋼輥101的研磨粉被連續地電解除去(電解修整),能夠保持磨石102的磨粒與鋼輥101接觸的狀態,研磨性提升。再者,來自電源104的供電對象為電極401(第一電極)及電極601(第二電極),藉此對旋轉驅動的磨石102的藉由電刷的直接供電或透過軸承301的供電變得不必要。
By means of the
於此,設置電極401(第一電極)及電極601(第二電極)的位置沒有特別限定,但是,只要其中一個電極設置於磨石102的鉛直下方,則不會壓迫磨石102的周圍的空間,再者,只要放置電極就能夠容易地設置。再者,如圖6B所示的變形例,只要其中一個電極設置於磨石102的鉛直上方,則例如像是淋浴般地利用重力,能夠於磨石102與電極之間的間隙效率良好地供給研磨液。
Here, the positions where the electrode 401 (first electrode) and the electrode 601 (second electrode) are provided are not particularly limited. However, as long as one of the electrodes is installed vertically below the
以上對本發明的較佳實施例進行了說明,但是本發明不限定於上述的實施例,在不脫離本發明的主旨的範圍內能夠進行各種變更。 The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention.
例如,能夠於電極面形成得以讓研磨液流動的細溝,並使從研磨液供給孔503供給的研磨液透過溝而遍布電極面的整體。藉此,更加提高對磨石與電極之間的間隙的研磨液的供給的平均性。
For example, fine grooves that allow the polishing liquid to flow can be formed on the electrode surface, and the polishing liquid supplied from the polishing
藉由根據本發明的電解修整裝置及電解修整方法,使對高速鋼的軋製輥的使用頻率增加,具有高功能表面的板及帶的製造的難易度下降。再者,根據本發明的電解修整裝置及電解修整方法亦能夠對工具鋼以外的高功能輥(例如:超硬輥或陶瓷輥)應用。再者,藉由根據本發明的電解修整裝置及電解修整方法,在冷軋製不鏽鋼等的高硬度、強韌性的材料的場面,除了表面品質的提升,尚使冷軋製不鏽鋼以外的高硬度、強韌性的材料的可能性增加,不鏽鋼以外的高硬度、強韌性的材料的用途擴大。再者,藉由根據本發明的電解修整裝置及電解修整方法,產生將比鋼具有更高強度、高韌性的材料(例如:超合金)作為熱軋製輥的材料而利用的可能性。 By using the electrolytic dressing device and the electrolytic dressing method according to the present invention, the frequency of use of high-speed steel rolling rolls is increased, and the difficulty of manufacturing plates and strips with high-functional surfaces is reduced. Furthermore, the electrolytic dressing device and the electrolytic dressing method according to the present invention can also be applied to high-functional rolls other than tool steel (for example: superhard rolls or ceramic rolls). Furthermore, by using the electrolytic dressing device and the electrolytic dressing method according to the present invention, in the case of cold-rolling high-hardness and high-toughness materials such as stainless steel, in addition to improving the surface quality, the possibility of cold-rolling high-hardness and high-toughness materials other than stainless steel is increased, and the use of high-hardness and high-toughness materials other than stainless steel is expanded. Furthermore, the electrolytic trimming device and electrolytic trimming method according to the present invention make it possible to use materials with higher strength and higher toughness than steel (e.g., superalloys) as materials for hot rolling.
