Description

本発明は、金属容器の容器胴部外周に微細な凹凸洗浄を形成するヘアライン加工方法に関する。 The present invention relates to a hair line process how to form fine irregularities cleaning container body outer periphery of the metal container.

従来のこの種の金属容器のヘアライン加工方法は、たとえば、特許文献１に記載のように、容器胴部をマンドレルに保持し、容器胴部と平行に配置される砥石等の加工具を相対回転させて容器胴部に接触させ、容器胴部表面に微細な凹凸線条を形成するようになっている。   A conventional hairline processing method for this type of metal container, for example, as described in Patent Document 1, holds a container body part on a mandrel, and relatively rotates a processing tool such as a grindstone arranged parallel to the container body part. It is made to contact a container trunk | drum, and a fine uneven | corrugated filament is formed in the container trunk | drum surface.

しかし、形成される凹凸線条は極めて細い溝であるために、切り粉によって加工具が目詰まりしやすく、凹凸線条の加工精度も悪くなるという問題があった。
特開２００４−３０７００２ However, since the concavo-convex line to be formed is an extremely thin groove, there is a problem that the processing tool is easily clogged by the cutting powder, and the processing accuracy of the concavo-convex line is deteriorated.
JP2004-307002

本発明は上記した従来技術の課題を解決するためになされたもので、その目的とするところは、ヘアライン加工手段の目詰まりを防止し、加工精度の高い金属容器のヘアライン加工方法を提供することにある。 The present invention has been made to solve the problems of the prior art described above, it is an object to prevent the clogging of the hair line process means, to provide a hair line process how a high processing precision metal container There is.

上記目的を達成するために、本請求項１に係る発明にあっては、円筒状の容器胴部表面にヘアライン加工手段によって多数の微細な凹凸線条を形成する絞り、しごき加工による成形工程での油分を含む潤滑剤が付着した状態の金属容器のヘアライン加工方法において、
前記ヘアライン加工手段が砥粒を結合する結合材として軟質樹脂を用いた弾性砥石から成り、前記金属容器をマンドレルで支持し、前記弾性砥石と金属容器及びマンドレルとを反対方向に周速差を以て回転させると共に、前記弾性砥石の加工部に中性洗剤から成る洗浄液を流し、前記弾性砥石による切り粉と同時に前記潤滑剤を洗い流しながら加工することを特徴とする。 In order to achieve the above object, in the invention according to claim 1, in the forming step by drawing and ironing to form a large number of fine irregular lines on the surface of the cylindrical container body by hairline processing means. In the hairline processing method of the metal container in a state where the lubricant containing the oil of
The hairline processing means is composed of an elastic grindstone using a soft resin as a binder for bonding abrasive grains , the metal container is supported by a mandrel, and the elastic grindstone, the metal container and the mandrel are rotated in the opposite direction with a peripheral speed difference. In addition, a cleaning liquid made of a neutral detergent is allowed to flow through a processing portion of the elastic grindstone, and the processing is performed while washing the lubricant simultaneously with cutting powder from the elastic grindstone.

本発明によれば、洗浄液によって弾性砥石に付着した切り粉が洗い流されるので、弾性砥石の目詰まりが防止される。
特に、金属容器の成形工程で付着した潤滑剤についても、界面活性剤を含む中性洗浄剤によって洗浄するようになっているので、潤滑剤の洗浄工程を削減することができ、生産性向上を図ることができる。 According to the present invention, since the chips adhering to the elastic grindstone are washed away by the cleaning liquid, clogging of the elastic grindstone is prevented.
In particular, for the lubricant adhering the molding process of the metallic container, because so is washed with a neutral detergent containing a surfactant, it is possible to reduce the cleaning process of the lubricant, improving productivity Can be achieved.

以下に本発明を図示の実施例に基づいて説明する。
図１は本発明の金属容器のヘアライン加工装置の概念図である。
すなわち、このヘアライン加工装置は、ヘアライン加工手段としての弾性砥石２０と、弾性砥石２０に金属容器１０を搬送するターンテーブル３０と、を備え、容器胴部１１表面に弾性砥石２０によって多数の微細な凹凸線条１３を形成するようになっている。そして、弾性砥石２０による加工部に対して、洗浄液を流す洗浄液供給手段としての洗浄ノズル４０が設けられている。 Hereinafter, the present invention will be described based on illustrated embodiments.
FIG. 1 is a conceptual diagram of a hairline processing apparatus for a metal container according to the present invention.
That is, this hairline processing apparatus includes an elastic grindstone 20 as a hairline processing means, and a turntable 30 that conveys the metal container 10 to the elastic grindstone 20, and a number of fine lines are formed on the surface of the container body 11 by the elastic grindstone 20. An uneven line 13 is formed. A cleaning nozzle 40 is provided as a cleaning liquid supply means for supplying a cleaning liquid to the processing portion by the elastic grindstone 20.

金属容器１０は、この実施例では絞り，しごき加工によって成形されたＤＩ缶で、容器胴部１１と底部１２が一体となっており、絞り，しごき工程での油分を含む潤滑剤が付着した状態でヘアライン加工が行われる。金属容器の材質としては、アルミニウム系材料でもよいし、ブリキ等の鋼板製のものでもよい。
弾性砥石２０は、砥粒を結合する結合材として軟質樹脂を用いたものである。 In this embodiment, the metal container 10 is a DI can formed by squeezing and ironing. The container body 11 and the bottom 12 are integrated, and a lubricant containing oil in the squeezing and ironing process is attached. Hairline processing is performed. The material of the metal container may be an aluminum-based material or a steel plate made of tin or the like.
Elastic grindstone 20, Ru der those using soft resin as a binder for binding the abrasive grains.

ターンテーブル３０には金属容器１０を支持するマンドレル３１が設けられている。マンドレル３１は円周方向に所定間隔でもって多数配置されており、絞り，しごき工程を経て成形された金属容器が、順次弾性砥石２０と対向する加工位置に送り込まれ、ヘアライン加工が終了した金属容器が順次後工程に搬送されるようになっている。もちろん、金属容器１０を搬送する手段としてはターンテーブルに限定されるものではなく、他の種々の搬送手段を用いることができる。
マンドレル３１は、不図示のモータによって回転駆動される。図示例では、マンドレル３１の回転方向Ｒ１０は、弾性砥石２０の回転方向Ｒ２０（図中、時計回り方向）とは反対方向（図中、反時計回り方向）で、周速差によって容器胴部１１に凹凸線条１３を形成する構成となっている。 The turntable 30 is provided with a mandrel 31 that supports the metal container 10. A large number of mandrels 31 are arranged at predetermined intervals in the circumferential direction, and a metal container formed through a drawing and ironing process is sequentially sent to a processing position facing the elastic grindstone 20, and the hairline processing is finished. Are sequentially conveyed to the subsequent process. Of course, the means for transporting the metal container 10 is not limited to the turntable, and other various transport means can be used.
The mandrel 31 is rotationally driven by a motor (not shown). In the illustrated example, the rotation direction R10 of the mandrel 31 is a direction (counterclockwise direction in the figure) opposite to the rotation direction R20 (clockwise direction in the figure) of the elastic grindstone 20, and the container body 11 is caused by the difference in peripheral speed. It is the structure which forms the uneven | corrugated filament 13 in this.

洗浄ノズル４０は、不図示の洗浄液供給装置に接続され、所定圧で洗浄液を弾性砥石２
０の加工部に噴射して切り粉を洗い流すようになっている。加工部とは弾性砥石２０と容器胴部１１の当接部である。洗浄ノズル４０の向きは、図１（Ａ）に示すように、容器胴部１１の側方から容器胴部１１の回転軸に対して直交する方向に噴射してもよいし、図１（Ｂ）に示すように、底部１２側から回転軸と平行方向に噴射するようにしてもよい。
洗浄液としては、界面活性剤の入った中性洗剤を用い、切粉と同時に成形工程での油分を含む潤滑剤も同時に洗い流すようになっている。従って、洗浄ノズル４０によって洗浄液を吹きかける領域は、金属容器１０の胴部１１から底部１２まで容器全体を洗浄するように設定される。 The cleaning nozzle 40 is connected to a cleaning liquid supply device (not shown) and supplies the cleaning liquid to the elastic grindstone 2 at a predetermined pressure.
It sprays on the processing part of 0 to wash away the chips. The processing part is a contact part between the elastic grindstone 20 and the container body part 11. As shown in FIG. 1 (A), the cleaning nozzle 40 may be sprayed from the side of the container body 11 in a direction perpendicular to the rotation axis of the container body 11 or as shown in FIG. As shown in (), the fuel may be ejected from the bottom 12 side in the direction parallel to the rotation axis.
As the cleaning liquid, a neutral detergent containing a surfactant is used, and at the same time, the lubricant containing the oil in the molding process is simultaneously washed away. Therefore, the region where the cleaning liquid is sprayed by the cleaning nozzle 40 is set so as to clean the entire container from the body 11 to the bottom 12 of the metal container 10.

洗浄液に使用する中性洗剤としては、絞り，しごき成形時に使用された潤滑剤の種類に応じて、適切な洗剤が選択される。界面活性剤についても同様に、潤滑剤に含まれる油分の種類等に応じて適切なものが選択される。
なお、本発明が適用される金属容器としては、２ピース缶に限らず、３ピース缶でもよい。 As the neutral detergent used for the cleaning liquid, an appropriate detergent is selected according to the type of lubricant used at the time of drawing and ironing. Similarly, an appropriate surfactant is selected according to the type of oil contained in the lubricant.
As the metal container to which the present invention is applied is not limited to the two-piece can, have good even three-piece cans.
