(57) [Abstract] [Purpose] To reduce the transportation cost of the sheet metal cover that constitutes the housing of the electronic device and prevent deformation during transportation. [Structure] In a bent portion of a sheet metal cover 1, a groove 2 is formed along a bending line to provide a plastically deformable portion. When the groove is bent around the groove portion 2, it can be bent with a comparatively small force so that the bent portion becomes a straight line. Therefore, since the bending can be performed at the assembly site without performing the bending in the sheet metal factory, the sheet metal cover 1 can be transported from the sheet metal factory to the assembly factory in a flat plate state. It can be transported efficiently and waste of transportation costs can be saved. In addition, the sheet metal cover will not be deformed during transportation.
Description
【０００１】[0001]
本考案は、金属板を折曲げて形成される電子機器用板金カバーに関するもので ある。 The present invention relates to a sheet metal cover for electronic devices, which is formed by bending a metal plate.
【０００２】[0002]
従来、電子機器としては、その筐体が多数の板金部品から構成されたものがあ る。筐体を構成する板金部品（以下、これを板金カバーという）は、断面形状が コ字状，Ｌ字状等に折曲げ形成されたものが多く使用されている。 2. Description of the Related Art Conventionally, as an electronic device, there is an electronic device whose housing is composed of many sheet metal parts. Many sheet metal parts (hereinafter, referred to as sheet metal covers) that form a housing are formed by bending a cross-section into a U-shape, an L-shape, or the like.
【０００３】 そして、この種の板金カバーは、通常はこの板金カバーを使用して電子機器を 組立てる工場とは別の工場で製造されていた。すなわち、板金カバー類は板金工 場で最終形状となるように曲げ加工されて製造され、その形状を保ったまま、換 言すれば略箱型の状態で、組立工場へ輸送されていた。And, this kind of sheet metal cover is usually manufactured in a factory different from a factory for assembling electronic devices using the sheet metal cover. That is, the sheet metal covers were manufactured by being bent into the final shape at the sheet metal factory, and were transported to the assembly plant while maintaining the shape, in other words, in a substantially box shape.
【０００４】[0004]
しかるに、上述したように最終形状に曲げ加工された板金カバーを板金工場か ら組立工場へ輸送すると、板金カバーが略箱型に形成されている関係から重量の 割に体積が嵩んでしまい、一度に運べる数量が少なくなってしまって輸送費に無 駄が生じる。また、輸送中に変形してしまうことも考えられる。 However, when the sheet metal cover bent into the final shape as described above is transported from the sheet metal factory to the assembly factory, the volume increases due to the weight of the sheet metal cover due to the fact that the sheet metal cover is formed in a substantially box shape. Since the quantity that can be carried to the customer is reduced, the shipping cost will be wasted. In addition, it may be deformed during transportation.
【０００５】[0005]
本考案に係る電子機器用板金カバーは、折曲部に、折曲げ線に沿う凹溝を形成 して塑性変形可能部を設けたものである。 The sheet metal cover for electronic devices according to the present invention is provided with a plastically deformable portion by forming a concave groove along the bending line at the bent portion.
【０００６】[0006]
本考案に係る電子機器用板金カバーは、凹溝部分を中心にして折曲げると、比 較的小さな力でしかも折曲部分が直線になるように折曲げられる。このため、曲 げ加工機を使用せずに正確にしかも簡単に曲げ加工を行なうことができる。 When the sheet metal cover for electronic devices according to the present invention is bent around the concave groove portion, it can be bent with a comparatively small force and the bent portion becomes a straight line. Therefore, it is possible to perform bending accurately and easily without using a bending machine.
【０００７】[0007]
以下、本考案の一実施例を図１ないし図３によって詳細に説明する。 図１は本考案に係る板金カバーを示す斜視図、図２は本考案に係る板金カバー の曲げ加工前の状態を示す斜視図、図３は本考案に係る板金カバーの凹溝形成部 を破断して示す断面図である。これらの図において、１は電子機器（図示せず） の筐体の一部を構成する板金カバーで、この板金カバー１は、平板状の塩ビ鋼板 等の鋼板からなり、主板１ａの端部に側板１ｂ，１ｃが一体に設けられている。 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 is a perspective view showing a sheet metal cover according to the present invention, FIG. 2 is a perspective view showing a state of the sheet metal cover according to the present invention before bending, and FIG. FIG. In these drawings, reference numeral 1 denotes a sheet metal cover which constitutes a part of a housing of an electronic device (not shown). The side plates 1b and 1c are integrally provided.
【０００８】 前記側板１ｂ，１ｃは、主板１ａの端部を直角に曲げ加工することによって形 成されている。The side plates 1b and 1c are formed by bending the ends of the main plate 1a at right angles.
【０００９】 ２は前記板金カバー１における側板１ｂ，１ｃが折曲げられる部分に形成され た凹溝で、この凹溝２は、曲げ内側となる部位に図３に示すよう断面半円形状に 形成され、側板１ｂ，１ｃの折曲げ線に沿うように直線状に形成されている。Reference numeral 2 denotes a concave groove formed in a portion of the sheet metal cover 1 where the side plates 1b and 1c are bent. The concave groove 2 has a semicircular cross section as shown in FIG. The side plates 1b and 1c are linearly formed along the bending lines.
【００１０】 この凹溝２は、板金カバー１となる平板状の鋼板をベンダー等によって加圧成 形して形成される。なお、図３において２ａは凹溝２を加圧成形法で形成するこ とに起因して凹溝２とは反対側に形成された凸部である。このように凹溝２を形 成すると、凹溝２の底部となる部分は板金カバー１の他の部位より肉厚が薄くな るので、その部分が実質的に塑性変形可能部となる。The recessed groove 2 is formed by press-molding a flat plate-shaped steel plate serving as the sheet metal cover 1 with a bender or the like. In FIG. 3, reference numeral 2a denotes a convex portion formed on the side opposite to the concave groove 2 due to the concave groove 2 being formed by a pressure molding method. When the groove 2 is formed in this manner, the bottom portion of the groove 2 has a thinner wall thickness than the other portions of the sheet metal cover 1, so that the portion substantially becomes a plastically deformable portion.
【００１１】 前記凹溝２の断面形状は、本実施例では、板金カバー１の板厚の約２／３の半 径をもつ半円形状とした。また、凸部２ａの高さ寸法は、板金カバー１の板厚の 約１／５とした。In the present embodiment, the concave groove 2 has a semicircular shape having a half diameter of about ⅔ of the plate thickness of the sheet metal cover 1. Further, the height dimension of the convex portion 2a is set to about 1/5 of the plate thickness of the sheet metal cover 1.
【００１２】 次に、上述した板金カバー１を製造する手順について説明する。 板金カバー１は、板金工場で所定寸法をもつ平板状に切断された後、側板１ｂ ，１ｃを折曲げる部分に凹溝２が形成される。凹溝２が形成された後の状態を図 ２に示す。そして、その状態で板金工場から組立工場へ出荷される。Next, a procedure for manufacturing the above-described sheet metal cover 1 will be described. The sheet metal cover 1 is cut into a flat plate having a predetermined size in a sheet metal factory, and then a groove 2 is formed in a portion where the side plates 1b 1 and 1c are bent. The state after the groove 2 is formed is shown in FIG. Then, in that state, the sheet metal factory is shipped to the assembly factory.
【００１３】 すなわち、組立工場へ輸送するには、平板状の板金カバー１を多数枚重ねた状 態で行われる。That is, transportation to an assembly plant is performed in a state where a large number of flat sheet metal covers 1 are stacked.
【００１４】 そして、組立工場において図２中二点鎖線で示すように凹溝２を中心として側 板１ｂ，１ｃを折曲げ、最終形状に加工する。なお、折曲げるときには、凹溝２ が曲げ部分の内側となるように曲げ、凹溝２の底部に設けられた塑性変形可能部 を塑性変形させて行なう。また、側板１ｂ，１ｃの曲げ加工は、作業者が折曲部 分を手で持って行うか、あるいは、治具等を使用して行なう。Then, in the assembly factory, the side plates 1b and 1c are bent around the concave groove 2 as shown by the chain double-dashed line in FIG. 2 and processed into the final shape. When bending, the concave groove 2 is bent so as to be inside the bent portion, and the plastically deformable portion provided at the bottom of the concave groove 2 is plastically deformed. The bending of the side plates 1b and 1c is performed by an operator holding the bent portion by hand or using a jig or the like.
【００１５】 したがって、凹溝２を中心にして折曲げると、比較的小さな力でしかも折曲部 分が直線になるように折曲げられるから、曲げ加工機を使用せずに曲げ加工を正 確にしかも簡単に行なうことができる。このため、組立現場で容易に曲げ加工で きるから、板金工場で曲げ加工を行わずに済ますことができる。Therefore, when the bending is performed with the concave groove 2 as the center, the bending can be performed with a comparatively small force so that the bent portion becomes a straight line. Therefore, the bending can be performed accurately without using a bending machine. Moreover, it can be done easily. Therefore, the bending work can be easily performed at the assembly site, and the bending work can be omitted at the sheet metal factory.
【００１６】 なお、本実施例では凹溝２を断面半円状に形成した例を示したが、他の部分よ り肉厚の薄い塑性変形可能部が設けられれば、どのような形状としても本実施例 と同等の効果が得られる。In the present embodiment, the example in which the concave groove 2 is formed to have a semicircular cross section is shown, but any shape may be used if a plastically deformable portion having a thinner wall thickness than other portions is provided. The same effect as that of the present embodiment can be obtained.
【００１７】[0017]
以上説明したように本考案に係る電子機器用板金カバーは、折曲部に、折曲げ 線に沿う凹溝を形成して塑性変形可能部を設けたため、凹溝部分を中心にして折 曲げると、比較的小さな力でしかも折曲部分が直線になるように折曲げられる。 このため、曲げ加工機を使用せずに正確にしかも簡単に曲げ加工を行なうことが できるから、板金工場では曲げ加工を行わずに組立現場にて曲げ加工を行なうこ とができるようになる。したがって、板金工場から組立工場へ板金カバーを輸送 するときには折曲部のない平板状態とすることができるので、効率よく輸送する ことができ、輸送費の無駄を省くことができる。また、輸送途中で板金カバーが 変形してしまうという不具合も解消することができる。 As described above, the sheet metal cover for an electronic device according to the present invention is provided with a plastically deformable portion by forming a concave groove along the bending line in the bent portion, and therefore, when bending the concave groove portion as the center. , It can be bent with a comparatively small force so that the bent portion becomes a straight line. For this reason, since it is possible to perform bending accurately and easily without using a bending machine, it becomes possible to perform bending at an assembly site without performing bending at a sheet metal factory. Therefore, when the sheet metal cover is transported from the sheet metal factory to the assembly factory, the sheet metal cover can be in a flat plate state without a bent portion, so that the sheet metal cover can be efficiently transported and waste of transportation cost can be saved. Further, it is possible to solve the problem that the sheet metal cover is deformed during transportation.
