Description

この発明は、鉛板の切断方法よび装置、特に、鉛板を金属ヒュームを発生させることなく、容易かつ確実にしかも安価に切断することができる、鉛板の切断方法および装置に関するものである。   The present invention relates to a lead plate cutting method and apparatus, and more particularly to a lead plate cutting method and apparatus capable of cutting a lead plate easily, reliably and inexpensively without generating metal fume.

例えば、原子力発電所の廃止措置作業の一つに、放射線の遮蔽材として用いられている鉛板の切断作業がある。   For example, one of the decommissioning work for nuclear power plants is cutting a lead plate used as a radiation shielding material.

鉛板の切断法として、鋼板等の切断に使用されるエアーソーやディスクグラインダー等の機械的切断機器を使用することが考えられるが、鉛は、金属の中で非常に軟らかい部類に属するので、切断中に切断機器の刃やディスクに鉛が入り込み、この結果、切断が円滑に行えないといった問題があった。   It is conceivable to use mechanical cutting equipment such as air saws and disc grinders used for cutting steel sheets, etc. as a cutting method for lead plates, but lead belongs to a very soft category among metals. There was a problem that lead entered into the blade and disk of the cutting device, and as a result, cutting could not be performed smoothly.

また、別の鉛板切断法として、バーナーによる熱切断が考えられるが、有害な金属ヒュームの発生等の問題がある。   As another lead plate cutting method, thermal cutting with a burner can be considered, but there are problems such as generation of harmful metal fume.

さらに、別の鉛板切断法として、レーザービームによる切断法が特許文献1に開示されているが、切断装置の構造が複雑で、コストがかかる。   Furthermore, as another lead plate cutting method, a laser beam cutting method is disclosed in Patent Document 1, but the structure of the cutting device is complicated and expensive.

この発明によれば、鉛板に超音波カッターの加熱した刃先をあてがい、BiとSnからなる合金材を刃先があてがわれた部分の鉛板に供給し、かくして、刃先があてがわれた部分の鉛板をBiとPbとSnからなる低融点合金として軟化させることによって、超音波カッターにより鉛板を金属ヒュームを発生させることなく、容易かつ確実にしかも安価に切断することができる。   According to this invention, the blade edge heated by the ultrasonic cutter is applied to the lead plate, and the alloy material composed of Bi and Sn is supplied to the lead plate of the portion to which the blade edge is applied, and thus the portion to which the blade edge is applied. By softening the lead plate as a low melting point alloy made of Bi, Pb and Sn, the lead plate can be easily and reliably cut at low cost without generating metal fume by an ultrasonic cutter.

また、この発明によれば、切断が終了した鉛板の切断部は、冷えた低融点合金を介して接着されるので、切断された鉛板が未切断の鉛板から分離するおそれはない。この結果、切断された鉛板の落下による事故を未然に防止することができる。なお、冷えた低融点合金は、金属結晶構造が粗いとともに鉛に比べて硬く、脆いために、切断された鉛板にハンマー等で打撃を加えると、切断された鉛板は、未切断の鉛板から容易に剥がれるので、鉛板の撤去作業は、容易に行える。   Further, according to the present invention, since the cut portion of the lead plate that has been cut is bonded via the cold low-melting point alloy, the cut lead plate is not likely to be separated from the uncut lead plate.

この発明の、鉛板の切断装置の一実施態様を、図面を参照しながら説明する。   An embodiment of the lead plate cutting device of the present invention will be described with reference to the drawings.

図1は、この発明の、鉛板の切断装置により鉛板を切断する状態を示す概略斜視図、図2は、この発明の、鉛板の切断装置により鉛板を切断する状態を示す概略断面図、図3は、鉛板の切断が進行した状態を示す概略断面図である。   FIG. 1 is a schematic perspective view showing a state in which a lead plate is cut by a lead plate cutting device according to the present invention, and FIG. 2 is a schematic cross section showing a state in which the lead plate is cut by the lead plate cutting device according to the present invention. FIG. 3 is a schematic sectional view showing a state where cutting of the lead plate has progressed.

図1から図3において、1は、鉛板である。鉛板1は、例えば、原子力発電所における、放射線の遮蔽材である。2は、板状の刃先3が鉛板1にあてがわれる超音波カッターである。刃先3は、電熱ヒーター4等により139℃以上に加熱される。5は、刃先3があてがわれる部分(S)(図1、図2参照)の鉛板1に、融点が139℃のBiとSnからなる合金材6を、ガイド7を介して供給する合金材供給手段である。   1 to 3, reference numeral 1 denotes a lead plate. The lead plate 1 is a radiation shielding material in a nuclear power plant, for example. Reference numeral 2 denotes an ultrasonic cutter in which a plate-like cutting edge 3 is applied to the lead plate 1. The blade edge 3 is heated to 139 ° C. or higher by an electric heater 4 or the like. 5 is an alloy for supplying, through a guide 7, an alloy material 6 composed of Bi and Sn having a melting point of 139 ° C. to the lead plate 1 of the portion (S) to which the blade edge 3 is applied (see FIGS. 1 and 2). It is a material supply means.

超音波カッター2は、刃物をその長手方向に10μmから70μmの幅で、毎秒20,000回から40,000回振動させて物を切断するカッターである。   The ultrasonic cutter 2 is a cutter that cuts an object by vibrating the blade in the longitudinal direction at a width of 10 μm to 70 μm and vibrating 20,000 to 40,000 times per second.

合金材6は、刃先3に合わせて、例えば、帯状に形成され、その融点は、139℃である。   The alloy material 6 is formed, for example, in a strip shape in accordance with the blade edge 3 and has a melting point of 139 ° C.

合金材供給手段5は、例えば、コイル状に巻かれた合金材6を順次、刃先3があてがわれる部分(S)の鉛板1に供給する。   For example, the alloy material supply means 5 sequentially supplies the alloy material 6 wound in a coil shape to the lead plate 1 of the portion (S) to which the blade edge 3 is applied.

この発明の、鉛板の切断装置により鉛板を切断するには、図1および図2に示すように、鉛板1に電熱ヒーター4により139℃以上に加熱された超音波カッター2の刃先3をあてがい、BiとSnからなる合金材6を刃先3があてがわれた部分(S)の鉛板1にガイド7を介して供給する。この場合、合金材6は、刃先3があてがわれた部分(S)に、刃先3に対して斜めに供給する。この理由は、先端部分以外の合金材6が加熱された刃先3に接触して溶融するのを防止するためである。   In order to cut the lead plate by the lead plate cutting apparatus of the present invention, as shown in FIGS. 1 and 2, the cutting edge 3 of the ultrasonic cutter 2 heated to 139 ° C. or higher by the electric heater 4 on the lead plate 1 is shown. The alloy material 6 made of Bi and Sn is supplied to the lead plate 1 of the portion (S) to which the blade edge 3 is applied via the guide 7. In this case, the alloy material 6 is supplied obliquely with respect to the blade edge 3 to the portion (S) to which the blade edge 3 is applied. The reason for this is to prevent the alloy material 6 other than the tip portion from coming into contact with the heated cutting edge 3 and melting.

合金材6の融点は、139℃であるので、合金材6は、鉛板1にあてがわれた刃先3と接触することにより溶融し、これによって、刃先3があてがわれた部分(S)の鉛板1は、融点が95℃のBiとPbとSnからなる低融点合金となり、液相になって軟化する。   Since the melting point of the alloy material 6 is 139 ° C., the alloy material 6 is melted by coming into contact with the blade edge 3 applied to the lead plate 1, thereby the portion to which the blade edge 3 is assigned (S). The lead plate 1 becomes a low melting point alloy composed of Bi, Pb and Sn having a melting point of 95 ° C., and becomes a liquid phase and softens.

この状態で、図3に示すように、超音波カッター2を合金材6の供給と共に下降させれば、合金材6が供給された部分(S)のBiとPbとSnからなる合金は、液相になって軟化し、これによって、鉛板1を金属ヒュームを発生させることなく、容易かつ確実にしかも安価に切断することができる。   In this state, as shown in FIG. 3, if the ultrasonic cutter 2 is lowered together with the supply of the alloy material 6, the alloy composed of Bi, Pb, and Sn in the portion (S) to which the alloy material 6 is supplied becomes liquid. As a result, the lead plate 1 can be easily and reliably cut at low cost without generating metal fume.

なお、図4に示すように、合金材6の供給側の刃先3の面に、鉛板1の切断方向に沿って溝8を形成すれば、BiとSnからなる合金材6の流れが形成されるので、BiとPbとSnからなる低融点合金が形成されやすくなる。これは、特に、鉛板1の切断が進行したときに有効である。   In addition, as shown in FIG. 4, if the groove | channel 8 is formed in the surface of the blade edge | tip 3 of the supply side of the alloy material 6 along the cutting direction of the lead plate 1, the flow of the alloy material 6 which consists of Bi and Sn will form. Therefore, a low melting point alloy composed of Bi, Pb, and Sn is easily formed. This is particularly effective when the cutting of the lead plate 1 proceeds.

切断が終了した鉛板の切断部は、冷えた低融点合金を介して接着されるので、切断された鉛板が未切断の鉛板から分離するおそれはない。この結果、切断された鉛板の落下による事故を未然に防止することができる。なお、冷えた低融点合金は、金属結晶構造が粗いとともに鉛に比べて硬く、脆いために、切断された鉛板にハンマー等で打撃を加えると、切断された鉛板は、未切断の鉛板から容易に剥がれるので、鉛板の撤去作業は、容易に行える。   Since the cut portion of the lead plate that has been cut is bonded via the cold low melting point alloy, the cut lead plate is not likely to be separated from the uncut lead plate. As a result, it is possible to prevent an accident caused by dropping the cut lead plate. In addition, since the cold low melting point alloy has a rough metal crystal structure and is harder and more brittle than lead, when a hammer is applied to the cut lead plate, the cut lead plate becomes uncut lead Since it peels easily from a board, the removal operation of a lead board can be performed easily.

以上、説明したように、この発明によれば、鉛板1に超音波カッター2の139℃以上に加熱された刃先3をあてがい、合金材供給手段5から融点が139℃のBiとSnからなる合金材6を、刃先3があてがわれた部分(S)の鉛板1に供給する。これにより、合金材6は、鉛板1にあてがわれた刃先3と接触することにより溶融して、刃先3があてがわれた部分(S)の鉛板1は、融点が95℃のBiとPbとSnからなる低融点合金となり、液相になって軟化する。これによって、鉛板1を超音波カッター2により金属ヒュームを発生させることなく、容易かつ確実にしかも安価に切断することができる。   As described above, according to the present invention, the cutting edge 3 heated to 139 ° C. or higher of the ultrasonic cutter 2 is applied to the lead plate 1, and the alloy material supply means 5 comprises Bi and Sn having a melting point of 139 ° C. The alloy material 6 is supplied to the lead plate 1 of the portion (S) to which the blade edge 3 is applied. Thereby, the alloy material 6 is melted by contact with the cutting edge 3 applied to the lead plate 1, and the lead plate 1 of the portion (S) to which the cutting edge 3 is applied has a melting point of 95 ° C. Bi. It becomes a low melting point alloy composed of Pb and Sn and becomes a liquid phase and softens. Thus, the lead plate 1 can be easily and reliably cut at low cost without generating metal fume by the ultrasonic cutter 2.

また、この発明によれば、切断が終了した鉛板の切断部は、冷えた低融点合金を介して接着されるので、切断された鉛板が未切断の鉛板から分離するおそれはない。この結果、切断された鉛板の落下による事故を未然に防止することができる。なお、冷えた低融点合金は、金属結晶構造が粗いとともに鉛に比べて硬く、脆いために、切断された鉛板にハンマー等で打撃を加えると、切断された鉛板は、未切断の鉛板から容易に剥がれるので、鉛板の撤去作業は、容易に行える。   Further, according to the present invention, since the cut portion of the lead plate that has been cut is bonded via the cold low-melting point alloy, the cut lead plate is not likely to be separated from the uncut lead plate. As a result, it is possible to prevent an accident caused by dropping the cut lead plate. In addition, since the cold low melting point alloy has a rough metal crystal structure and is harder and more brittle than lead, when a hammer is applied to the cut lead plate, the cut lead plate becomes uncut lead Since it peels easily from a board, the removal operation of a lead board can be performed easily.
