Description

この発明は、腐食試験機に係り、噴霧手段から噴霧された霧状の液体中に試料を均一に晒すことができる腐食試験機に関する。   The present invention relates to a corrosion tester, and more particularly to a corrosion tester capable of uniformly exposing a sample to a mist-like liquid sprayed from spraying means.

腐食試験機は、塗装、メッキ、アルマイト等の金属表面処理や金属材料の腐食性（防錆性、防食性）を評価するために用いられている。
このような腐食試験機には、塩水噴霧試験機、塩乾湿の複合サイクル試験機、ガス腐食試験機等の各試験機がある。
塩水噴霧試験機は、試験槽内を所定の温度状態に維持しつつ、塩水の噴霧を行い、試料の防錆・防食効果を調べるためのものであり、短時間で試料の腐食性を知ることができ、自動車、住宅、家電製品、日常生活用品等のあらゆる工業製品の試験に使用されている。 The corrosion tester is used for evaluating metal surface treatments such as painting, plating, anodized, and the corrosiveness (rust prevention and corrosion resistance) of metal materials.
Such corrosion testers include various test machines such as a salt spray tester, a salt dry / wet combined cycle tester, and a gas corrosion tester.
The salt spray tester is for spraying salt water while maintaining the inside of the test tank at a specified temperature, and examining the anti-corrosion and anti-corrosion effect of the sample. Know the corrosivity of the sample in a short time It is used for testing all industrial products such as automobiles, homes, home appliances and daily life products.

特許第４２４７７９９号公報 特許文献１に記載の塩水噴霧試験機は、霧状の液体を噴出する噴出口が備えられた噴霧塔（噴霧手段）の周りで、試料を所定の回動速度で且つ他方向に間欠的に回転させるものである。Patent No. 4247799 gazette The salt spray tester described in Patent Document 1 has a sample rotated at a predetermined rotational speed around a spray tower (spraying means) provided with a spout for ejecting a mist-like liquid. It rotates intermittently in the direction.

ところで、従来、塩水噴霧試験機においては、噴霧手段から霧状の溶液（塩水）が噴霧されるが、噴霧手段と試験槽内の左右部位や前後部位に載置される試料との間の距離にバラツキが生じ、また、霧状の溶液の飛んで行く距離がその質量によって異なることから、試料への霧状の液体の降下（降霧）が均一にならず、このため、試料の設置場所により試験結果が異なるという不都合があった。   Conventionally, in a salt spray tester, a mist solution (salt water) is sprayed from the spraying means, but the distance between the spraying means and the samples placed on the left and right parts and the front and rear parts in the test tank. Since the mist-like solution flies and the distance that the mist-like solution flies varies depending on its mass, the mist-like liquid drops (falling) on the sample do not become uniform. There was an inconvenience that the test results differed.

そこで、この発明の目的は、試料を載置する載置台を噴霧手段の周りで回転させるとともに、載置台自体を回転させて、噴霧手段から噴霧された霧状の液体中に試料を均一に晒し、試験結果にムラを生じさせることなく、正確な腐食促進試験を実施する腐食試験機を提供することにある。   Therefore, an object of the present invention is to rotate the mounting table on which the sample is placed around the spraying means and rotate the mounting table itself so that the sample is uniformly exposed to the mist-like liquid sprayed from the spraying means. An object of the present invention is to provide a corrosion tester that performs an accurate corrosion acceleration test without causing unevenness in test results.

この発明は、試験槽内で霧状の液体を噴出する噴出口が備えられた噴霧手段を設け、この噴霧手段から噴霧された霧状の液体を試料に降りかけて試料の腐食促進試験を実施する腐食試験機において、試料が載置される載置台を前記噴霧手段の周りで回転させるとともに前記載置台自体を回転させる回転機構とこの回転機構を作動する駆動手段とが備えられた試料回転装置を設け、この試料回転装置を作動制御する制御手段を設けたことを特徴とする。   This invention is provided with a spraying means provided with a jet outlet for jetting a mist-like liquid in a test tank, and the mist-like liquid sprayed from this spraying means is dropped on the sample to carry out a corrosion promotion test on the sample. In the corrosion testing machine, a sample rotating device provided with a rotating mechanism for rotating the mounting table on which the sample is mounted around the spraying means and rotating the mounting table itself, and a driving means for operating the rotating mechanism And a control means for controlling the operation of the sample rotating device.

この発明の腐食試験機は、試料を載置する載置台を噴霧手段の周りで回転させるとともに、載置台自体を回転させることから、噴霧手段から噴霧された霧状の液体中に試料を均一に晒し、試験結果にムラを生じさせることなく、正確な腐食促進試験を実施できる。   The corrosion testing machine according to the present invention rotates the mounting table on which the sample is placed around the spraying means, and also rotates the mounting table itself, so that the sample is uniformly distributed in the mist-like liquid sprayed from the spraying means. Exact corrosion acceleration test can be carried out without exposing the test results to unevenness.

この第１〜第４支持枠３７−１〜３７−４の先端には、第１〜第４軸受３８−１〜３８−４を介して第１〜第４試料側歯車３９−１〜３９−４が水平方向で回転可能に設けられている。この第１〜第４試料側歯車３９−１〜３９−４は、同一平面上に配置され、上面に第１〜第４載置台２６−１〜２６−４を所定の固定手段によって固定している。 In the device space 8, a lower fixing member 29 is provided on the outer peripheral surface of the lower portion of the fixing shaft 14.
The lower fixing member 29 is provided with a lower portion of a rotating shaft 31 that is concentric with the fixing shaft 14 via a lower bearing 30 and that is larger than the diameter of the fixing shaft 14. .
The rotating shaft 31 is rotatably supported by an upper bearing 33 of an upper fixing member 32 attached to the lower surface of the salt water container 16 at the upper part.
In the device space 8, a driven gear 34 is fixed in the horizontal direction below the outer peripheral surface of the rotation shaft 31. The driven gear 34 meshes with a drive gear 35 of a drive motor 28 attached to the upper surface of the lower support plate 6.

First to fourth support frames 37-1 to 37-4 corresponding to the first to fourth mounting tables 26-1 to 26-4 are fixed to the upper portion of the rotation shaft 31 in the test chamber 9. . One end of each of the first to fourth support frames 37-1 to 37-4 is fixed to the outer peripheral surface of the rotating shaft 31 at equal intervals in the circumferential direction in plan view, and is bent upward in an L shape.

Yes.

一方、噴霧塔１８の外周面には、第１〜第４試料側歯車３９−１〜３９−４に噛み合うように、水平方向に配置された噴霧手段側歯車としての塔側歯車４０が設けられている。なお、この塔側歯車４０は、直接噴霧塔１８の外周面に固定したり、あるいは、軸受（図示せず）を介して噴霧塔１８の外周面に回転可能に設けることも可能である。
塔側歯車４０は、第１〜第４試料側歯車３９−１〜３９−４の上面に第１〜第４載置台２６−１〜２６−４を載置することから、この第１〜第４載置台２６−１〜２６−４と干渉しないように、その幅が第１〜第４試料側歯車３９−１〜３９−４の幅よりも小さく設定され、且つ、第１〜第４試料側歯車３９−１〜３９−４の上面よりも下方に位置して第１〜第４試料側歯車３９−１〜３９−４に噛み合っている。
従って、図２に示すように、第１〜第４試料側歯車３９−１〜３９−４は、回動軸３１の回転方向（Ａ）で噴霧塔１８の周りで回転（公転）すると、塔側歯車４０に噛み合っていることから、回動軸３１の回転方向（Ａ）と同じ方向（Ｂ）で回転（自転）する。
これら第１〜第４試料側歯車３９−１〜３９−４及び塔側歯車４０は、噴霧塔１８の噴出口１７よりも下方に配置されている。
また、第１〜第４載置台２６−１〜２６−４、第１〜第４試料側歯車３９−１〜３９−４及び塔側歯車４０は、塩化ビニル等の腐食しない樹脂素材によって形成されている。 On the other hand, on the outer peripheral surface of the spray tower 18, a tower side gear 40 as a spray means side gear disposed in the horizontal direction is provided so as to mesh with the first to fourth sample side gears 39-1 to 39-4. ing. The tower side gear 40 can be directly fixed to the outer peripheral surface of the spray tower 18 or can be rotatably provided on the outer peripheral surface of the spray tower 18 via a bearing (not shown).
Since the tower side gear 40 mounts the first to fourth mounting tables 26-1 to 26-4 on the upper surfaces of the first to fourth sample side gears 39-1 to 39-4, the first to fourth sample side gears 39-1 to 39-4 are mounted. The width is set smaller than the widths of the first to fourth sample-side gears 39-1 to 39-4 so as not to interfere with the four mounting tables 26-1 to 26-4, and the first to fourth samples. It is located below the upper surface of the side gears 39-1 to 39-4 and meshes with the first to fourth sample side gears 39-1 to 39-4.
Therefore, as shown in FIG. 2, when the first to fourth sample side gears 39-1 to 39-4 rotate (revolve) around the spray tower 18 in the rotation direction (A) of the rotation shaft 31, Since it is meshed with the side gear 40, it rotates (rotates) in the same direction (B) as the rotational direction (A) of the rotation shaft 31.
The first to fourth sample side gears 39-1 to 39-4 and the tower side gear 40 are disposed below the jet port 17 of the spray tower 18.
The first to fourth mounting tables 26-1 to 26-4, the first to fourth sample-side gears 39-1 to 39-4, and the tower-side gear 40 are made of a resin material that does not corrode such as vinyl chloride. ing.

試験室９には、この試験室９の温度を測定する測温センサ４１が配設される。
空気圧縮機２４と駆動モータ２８と測温センサ４１とは、制御盤４２に内蔵された制御手段４３に連絡している。 A temperature measuring sensor 41 for measuring the temperature of the test chamber 9 is disposed in the test chamber 9.
The air compressor 24, the drive motor 28, and the temperature sensor 41 are in communication with a control means 43 built in the control panel 42.

この制御手段４３は、空気圧縮機２４等の機器を作動制御する運転制御部４３Ａを備え、また、試料回転制御部４３Ｂを備えて、駆動モータ２８を駆動制御することによって試料回転装置２５を作動して第１〜第４載置台２６−１〜２６−４の回転状況を変更、例えば、回動軸３１の回転速度を変化して第１〜第４載置台２６−１〜２６−４の回転速度を変更させたり、回動軸３１の回転方向を所定時間毎で正方向と逆方向とに変更させて第１〜第４載置台２６−１〜２６−４の回転方向を変更する。   The control means 43 includes an operation control unit 43A that controls the operation of devices such as the air compressor 24, and also includes a sample rotation control unit 43B that operates the sample rotation device 25 by controlling the drive motor 28. Then, the rotation status of the first to fourth mounting tables 26-1 to 26-4 is changed, for example, the rotation speed of the rotating shaft 31 is changed to change the rotation speed of the first to fourth mounting tables 26-1 to 26-4. The rotation speed of the first to fourth mounting tables 26-1 to 26-4 is changed by changing the rotation speed or changing the rotation direction of the rotation shaft 31 between a normal direction and a reverse direction every predetermined time.

次に、この実施例に係る試料回転装置２５の動作を説明する。
図２に示すように、制御手段４３からの制御信号により駆動モータ２８が駆動し、この駆動モータ２８の駆動によって回動軸３１が回動して、この回動軸３１の回動に伴って第１〜第４載置台２６−１〜２６−４が噴霧塔１８の周りで回転（公転：図２の矢印Ａで示す）するとともに、第１〜第４試料側歯車３９−１〜３９−４が塔側歯車４０に噛み合っていることから、第１〜第４試料側歯車３９−１〜３９−４自体が回転（自転：図２の矢印Ｂで示す）する。つまり、第１〜第４載置台２６−１〜２６−４は、第１〜第４試料側歯車３９−１〜３９−４と共に回転（自転：図２の矢印Ｂで示す）する。
これにより、噴霧塔１８の噴出口１７から噴霧された霧状の液体が、噴霧塔１８の周りで回転且つそれ自体で回転する第１〜第４載置台２６−１〜２６−４上の試料Ｐに均一に降りかかり（降霧）、噴霧塔１８から噴霧された霧状の液体を試料Ｐに均一に供給して晒すことができ、試料Ｐの試験結果にムラが生じることをなくし、正確な腐食促進試験を実施できる。
また、試料回転装置２５は、駆動モータ２８によって回動される回動軸３１と、この回動軸３１に固定した第１〜第４支持枠３７−１〜３７−４と、この第１〜第４支持枠３７−１〜３７−４の先端に回転可能に設けられて第１〜第４載置台２６−１〜２６−４を保持する第１〜第４試料側歯車３９−１〜３９−４と、この第１〜第４試料側歯車３９−１〜３９−４に噛み合って噴霧塔１８に設けられた塔側歯車４０とを備える。このような構造により、試料回転装置２５の構成を簡単にすることができる。
更に、駆動モータ２８を駆動することによって試料回転装置２５を作動させて第１〜第４載置台２６−１〜２６−４の回転状況を変更することから、試料Ｐの試験結果にムラが生じることを効率的に抑制できる。更に、第１〜第４載置台２６−１〜２６−４を、一方向に所定回転数で回転させた後に、逆方向に所定回転数で回転させることも可能である。 Next, the operation of the sample rotating device 25 according to this embodiment will be described.
As shown in FIG. 2, the drive motor 28 is driven by the control signal from the control means 43, and the rotation shaft 31 is rotated by the drive of the drive motor 28. The first to fourth mounting tables 26-1 to 26-4 rotate around the spray tower 18 (revolution: indicated by an arrow A in FIG. 2) and the first to fourth sample-side gears 39-1 to 39-. Since 4 is meshed with the tower side gear 40, the first to fourth sample side gears 39-1 to 39-4 themselves rotate (rotation: indicated by an arrow B in FIG. 2). That is, the first to fourth mounting tables 26-1 to 26-4 rotate (rotation: indicated by an arrow B in FIG. 2) together with the first to fourth sample-side gears 39-1 to 39-4.
Thereby, the mist-like liquid sprayed from the jet outlet 17 of the spray tower 18 rotates around the spray tower 18 and rotates on the first to fourth mounting tables 26-1 to 26-4. Evenly falls on P (fogging), and the mist-like liquid sprayed from the spray tower 18 can be uniformly supplied to and exposed to the sample P. A corrosion acceleration test can be performed.
The sample rotating device 25 includes a rotating shaft 31 rotated by the drive motor 28, first to fourth support frames 37-1 to 37-4 fixed to the rotating shaft 31, and the first to fourth support frames 37-1 to 37-4. First to fourth sample-side gears 39-1 to 39, which are rotatably provided at the tips of the fourth support frames 37-1 to 37-4 and hold the first to fourth mounting tables 26-1 to 26-4. -4 and a tower side gear 40 provided in the spray tower 18 so as to mesh with the first to fourth sample side gears 39-1 to 39-4. With such a structure, the configuration of the sample rotating device 25 can be simplified.
Furthermore, since the rotation state of the first to fourth mounting tables 26-1 to 26-4 is changed by operating the sample rotating device 25 by driving the drive motor 28, the test result of the sample P is uneven. This can be efficiently suppressed. Further, after the first to fourth mounting tables 26-1 to 26-4 are rotated in one direction at a predetermined number of rotations, it is also possible to rotate in the opposite direction at a predetermined number of rotations.

なお、この実施例においては、第１〜第４試料側歯車３９−１〜３９−４や塔側歯車４０の径や歯数を変更することにより、第１〜第４載置台２６−１〜２６−４の回転速度等を変化させて、試料Ｐの試験結果にムラが生じることをなくし、正確な腐食促進試験を実施できる。   In this embodiment, the first to fourth mounting tables 26-1 to 26-1 are changed by changing the diameter and the number of teeth of the first to fourth sample-side gears 39-1 to 39-4 and the tower-side gear 40. By changing the rotational speed of 26-4, the test result of the sample P is prevented from becoming uneven, and an accurate corrosion acceleration test can be performed.

この発明に係る試料回転装置を、塩水噴霧試験機のみならず、複合サイクル試験機やガス腐食試験機等の他の腐食試験機にも適用できる。   The sample rotating device according to the present invention can be applied not only to a salt spray tester but also to other corrosion testers such as a combined cycle tester and a gas corrosion tester.
