(57) [Summary] [Problem] The present invention relates to the peeling of a spot welded portion. The welded portion is securely positioned, the core starts to be pierced without swinging, the upper sheet metal and the lower sheet metal are peeled, and the lower sheet metal part is convex. Separating the upper and lower sheet metal in a flat state without leaving any parts or recesses,
It is characterized in that processing after separation is omitted. Furthermore, in order to cope with the hardening of the spot weld, a hard metal is used as the material of the cutting blade.
Description
【０００１】 〔考案の属する技術分野〕 本考案はスポット熔接部の重ね板金をはがす為の刃物に関するもので、作業者 のフリーハンド作業で確定位置をズラさず確実に熔接部を除去し尚且つ重ね板金 の上板金には最小径の穴をあけ下板金には上板金の残骸の凸状を残さず同時に下 板金にはセンターのキズ凹状も残さず平坦な状態ではがすことを特徴とするスポ ットはがしホールソーに関するものである。[0001] The present invention relates to a blade for peeling off a sheet metal of a spot welding portion, and reliably removes a welding portion without shifting a fixed position by a freehand operation of an operator. A hole with the smallest diameter is drilled in the upper sheet metal of the stacked sheet metal, and the lower sheet metal is peeled off in a flat state without leaving the concave shape of the center on the lower sheet metal without leaving the convex shape of the debris of the upper sheet metal. The cut is related to the hole saw.
【０００２】 〔従来の技術〕 従来、スポット熔接部の重ね板金のはがしには、スポット熔接面積よりも寸法 の大きい環状穿孔刃物でリング状溝をあけて重ね部をはがす方法があったがリン グ溝状切削では下方の板金部にピンがフリーなので凸状の熔接部が残り後で除去 する必要があった。又別の方法ではドリルの研ぎ方を変えて（凸部の残るホール ソータイプとは逆に）熔接部を全体に除去するドリル方式ではドリルの先端突部 が下方の板金部に入り込むので除去部は凹の穴が残り埋めて平坦にする必要があ った。[Prior art] Conventionally, there has been a method of peeling off the overlapped sheet metal at the spot welding portion by peeling off the overlapping portion by making a ring-shaped groove with an annular drilling tool having a dimension larger than the spot welding area. In the groove-shaped cutting, a pin is free on the lower sheet metal part, so a convex welded part remains and must be removed later. In another method, the method of sharpening the drill is changed (as opposed to the hole saw type where the protruding portion remains), and in the drilling method where the welded part is entirely removed, the protruding part of the drill enters the lower sheet metal part. The remaining concave holes had to be filled and flattened.
【０００３】 〔考案が解決しようとする課題〕 前記重ね板のスポット熔接部を下方板金に凸部も凹部も残さずに平坦に近い状 態ではずせるスポットはがしホールソーを提供するものである。[Problem to be Solved by the Invention] An object of the present invention is to provide a spot peeling hole saw capable of removing a spot welded portion of the above-mentioned laminated plate in a nearly flat state without leaving a convex portion or a concave portion on a lower sheet metal.
【０００４】 〔課題を解決する為の手段〕 本考案は上記の目的を達成する為にホールソーの中心部近くまで切刃を位置し 、センターの位置決めと求芯性の維持に先端だけ切刃を兼ねたセンターピンを備 えスポット熔接部の除去を行い下方板金には凹部も凸部も有しない平坦な形状で はがせることを特徴とする。[Means for Solving the Problems] In order to achieve the above object, the present invention locates the cutting blade close to the center of the hole saw, and only uses the cutting blade at the tip to position the center and maintain the centering property. It is equipped with a center pin that also serves as a spot welding part, and the lower sheet metal can be peeled off in a flat shape without any concave or convex parts.
【０００５】 〔考案の実施形態〕 本考案はスプリングによるピン圧力でセンターの位置決めを行い、センター近 くまで位置する切刃ででセンター部に凸を残さず、センターのドリルでは下方板 金にキズがつくのをピンにしてスポット熔接部をきれいにはがすものである。[0005] [Embodiment of the present invention] In the present invention, the center of the center is positioned by the pin pressure of the spring, and the cutting edge positioned close to the center does not leave a protrusion at the center part. The spot welding part is to be peeled off using the pin as a pin.
【０００６】 〔実施例〕 以下本考案のスポットはがしホールソーを実施例に基づいて詳細に説明する。 第１図は本考案のスポットはがしホールソーを示す斜視図である。第２図は断面 図で第１図、第２図を参照するにスポットはがしホールソー１は概略的には円筒 状の本体２とセンターピン３、巾小刃４と巾大刃５、スプリング６とスプリング 圧調整ネジ７で形成される。Embodiment Hereinafter, a spot peeling hole saw of the present invention will be described in detail based on an embodiment. FIG. 1 is a perspective view showing a spot peeling hole saw of the present invention. FIG. 2 is a cross-sectional view. Referring to FIGS. 1 and 2, the spot peeling hole saw 1 has a cylindrical main body 2 and a center pin 3, a small blade 4 and a large blade 5, and a spring 6. It is formed by a spring pressure adjusting screw 7.
【０００７】 第３図は従来のスポットはがしに使われているホールソーとドリルを示す。下 方板金にはいずれも凸部が残るか凹部が残り後加工が必要となる。FIG. 3 shows a hole saw and a drill used for a conventional spot peeling. In any case, the lower sheet metal needs to be processed after the protrusions or recesses remain.
【０００８】 次に第４図について本考案のスポットはがしホールソーについて説明する。（ Ａ）図は上方板金８と下方板金９をスポット熔接部１０でつながっているがこれ をはがす為に本体２を回転させながら降ろしていくとセンターピン３が上方板金 ８に接触しスプリング６の圧力によってセンターピン３の先端切欠Ｖ形状が上方 板金８の微小のキズ穴をあけて位置決めと求芯性を確保する。更に降下を進行す ると（Ｂ）図の如く巾小刃４と巾大刃５が上方板金８を切削する。センターピン ３は同時に回転しながらスプリング６を押し上げピン溝に沿って巾大刃をキーと してひっこんでいく。Next, the spot peeling hole saw of the present invention will be described with reference to FIG. (A) In the figure, the upper sheet metal 8 and the lower sheet metal 9 are connected by a spot welding portion 10, but when the body 2 is lowered while rotating to remove it, the center pin 3 comes into contact with the upper sheet metal 8 and the spring 6 Due to the pressure, the notch V shape of the center pin 3 makes a fine scratch hole in the upper sheet metal 8 to secure positioning and centripetality. As the descent proceeds further, the small blade 4 and the large blade 5 cut the upper sheet metal 8 as shown in FIG. The center pin 3 rotates at the same time and pushes up the spring 6 to pull in along the pin groove with the large blade as a key.
【０００９】 巾小刃４と巾大刃５が下方板金９に至った時点を（Ｃ）図に示す。巾小刃４と 巾大刃５の切刃差はスラグ１２で示されるがこれは微小凸形状の為にセンターピ ン３の先端で押しつぶされてしまう（Ｄ）図に示す如く穴あけが終りスポットは がしホールソー１を上方に引き上げて上方板金８と下方板金９は分離する。その 時の中央に残っているスラグ１２は押さえられ変形して１２”となりほとんど形 を為しておらず後加工に影響がない。The time when the small blade 4 and the large blade 5 reach the lower sheet metal 9 is shown in FIG. The difference in the cutting edge between the small blade 4 and the large blade 5 is indicated by a slug 12, which is crushed at the tip of the center pin 3 because of the minute convex shape. (D) Drilling ends as shown in the figure. The hole saw 1 is pulled up to separate the upper sheet metal 8 and the lower sheet metal 9. The slag 12 remaining in the center at that time is pressed and deformed to 12 ", and has almost no shape, so that there is no influence on post-processing.
【００１０】 〔考案の効果〕 以上の如き実施例の説明から理解される様に本考案は請求の範囲に記載した構 成となっているからスポット熔接の重ね部に於けるはがし作業に関して下方板金 に凸部も残さず凹部も残さず平坦な形状を有しながら上下の板金をはがすことが 出来る様になった。切刃は熔接部硬化に対応して超硬金属刃を接合している。[Effects of the Invention] As can be understood from the above description of the embodiment, the present invention has the structure described in the claims, and therefore, the lower sheet metal is used for the stripping work in the overlapped portion of spot welding. The upper and lower sheet metals can be peeled off while having a flat shape with no protrusions or recesses left. The cutting blade joins the cemented carbide metal blade corresponding to the hardened weld.
