本発明は白熱電球用のフィラメントのレグ部を挿入する

リーブの挿入口に、バlJ’を生じさせないスリーブの
製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of manufacturing a sleeve into which a leg portion of a filament for an incandescent light bulb is inserted. The present invention relates to a method for manufacturing a sleeve that does not cause the occurrence of.
一般に、スリーブは、フィラメントのレグ部ケ挿入する
ために1円筒状に加工されている。Generally, the sleeve is machined into a cylindrical shape for inserting the legs of the filament.
従来のこの種のスリーブの製造方法は、モリブデン等の
金属又は合金からなる線を、圧延加工によりテープ状に
成形し、これを丸め加工により徐々に円筒状に加工し、
一旦、所謂長尺スリーブを形成する。その後、このよう
にして得られた長尺スリーブを50本程度束ねて9例え
ば、熱収縮性のあるヒシチューブ詰めにし、所望の長さ
くt=2〜5mm)に切断加工し、ヒシチューブ全取り
去る。The conventional method for manufacturing this type of sleeve is to form a wire made of metal or alloy such as molybdenum into a tape shape by rolling, and then gradually shape it into a cylindrical shape by rolling it.
First, a so-called long sleeve is formed. After that, about 50 long sleeves obtained in this way are bundled into 9, for example, heat-shrinkable calico tubes, cut into a desired length (t = 2 to 5 mm), and the calico tubes are completely removed. .
ところが9本発明者等の観察によれば、この切断加工の
際に、切断面に沿って、パリが生じる場合があり、この
パリの発生率は切断加工されたスリーブの約30%でも
達していることが判明した。しかも、・クリが発生して
いる切断端面ハウスリーブの端面、即ち、フィラメント
のレグ部が挿入される挿入口に位置付けられるものであ
るから、切断端面におけるパリはレグ部をスリーブにス
ムーズに挿入する際に大きな障害となっている。However, according to the observations of the present inventors, burrs may occur along the cut surface during this cutting process, and the occurrence rate of burrs reaches approximately 30% of the cut sleeve. It turned out that there was. Moreover, since the cut end surface where the crevice occurs is located at the end surface of the house sleeve, that is, the insertion opening into which the leg portion of the filament is inserted, the crease on the cut end surface allows the leg portion to be smoothly inserted into the sleeve. This has become a major obstacle.
そこで、このパリ全エツチングにより除去することが考
えられている。Therefore, it has been considered to remove the particles by etching the entire surface.
しかしながら、エツチング法によるパリの除去は、スリ
ーブ自体の肉厚を薄くするばかりか、エツチング後の洗
浄工程及び還元雰囲気内でのアニール工程等の余分な工
程全必要とし、しかも、パリの残存の可能性が高く2歩
留りが悪いという欠点がある。However, removing paris by the etching method not only reduces the thickness of the sleeve itself, but also requires additional steps such as a cleaning process after etching and an annealing process in a reducing atmosphere, and there is a possibility that paris may remain. It has the disadvantage of high yield and low yield.
そこで1本発明は上記問題点に鑑み、製造工程全簡素化
し、しかも、パリの発生のない白熱電球用スリーブの製
造方法を提供するものである。In view of the above-mentioned problems, the present invention provides a method for manufacturing a sleeve for an incandescent light bulb, which simplifies the entire manufacturing process and does not cause sparks.

ーブの製造方法を得る。According to the present invention, a step of preparing a binding made of either a metal or an alloy, a step of cutting the wire across the axial direction, and a step of rolling the wire to form a tape. A method for manufacturing a sleeve for an incandescent light bulb is obtained, which comprises the steps of wrapping the tape around the outer periphery of a mandrel and then press-molding it into a cylindrical shape.
本発明の一実施例に係るスリーブの製造方法を図面を参
照して説明する。A method of manufacturing a sleeve according to an embodiment of the present invention will be described with reference to the drawings.
尚、ここではハロゲンランプ用のスリーブの製造方法に
適用した場合について説明する。Here, a case where the present invention is applied to a method of manufacturing a sleeve for a halogen lamp will be described.
まず、線を用意する工程(図示しない)において、径φ
= 1 mmの断面円形で、純度99.(lのモリ
ブデン線を用意する。First, in the process of preparing the wire (not shown), the diameter φ
= 1 mm circular cross section, purity 99. (Prepare l molybdenum wire.
次に、切断する工程(a)において、用意されたモリブ
デン線の軸方向を横切るように切断し、長さt=2〜5
mのモリブデン線1を得る。Next, in the cutting step (a), the prepared molybdenum wire is cut across the axial direction to a length t=2 to 5
m molybdenum wire 1 is obtained.
次に圧延してテープを形成する工程(b)において。Then in step (b) of rolling to form a tape.
切断されたモリブデン線1を、板厚t =0.1 mm
。The cut molybdenum wire 1 has a plate thickness t = 0.1 mm.
.
巾w = 3 ranのモリブデンテープ2に圧延加工
する。A molybdenum tape 2 having a width w = 3 ran is rolled.
このモリブデンテープ2は、モリブデン線1の切断端部
3,3に相当する切断端面4,4と、モリブデン線1の
軸方向に沿い、モリブデン線1の外周面5に相当する側
端面6,6と比較的中広の上面7及び下面7′とを備え
ている。このとき、モリブデンテープ2の一対の側端面
6.6には、モリブデンテープ2の板厚t = 0.1
mよりも小さい曲げ半径Rを持たせて圧延加工(c)
することが望ましい。一対の側端面6,6は、切断する
工程(、)を経ないモリブデン線1の外周面5を圧延加
工するものであるから、必然的に、パリの発生の全くな
い滑らかな部分であシ、シかも1本来的に所定の曲率を
有しているので、容易に圧延する際に曲げ半径Rを持た
せて圧延加工(c)することができる。This molybdenum tape 2 has cut end surfaces 4, 4 corresponding to the cut ends 3, 3 of the molybdenum wire 1, and side end surfaces 6, 6 corresponding to the outer peripheral surface 5 of the molybdenum wire 1 along the axial direction of the molybdenum wire 1. and a relatively medium-wide upper surface 7 and lower surface 7'. At this time, the pair of side end surfaces 6.6 of the molybdenum tape 2 have a thickness t = 0.1 of the molybdenum tape 2.
Rolling with a bending radius R smaller than m (c)
It is desirable to do so. Since the pair of side end surfaces 6, 6 are formed by rolling the outer circumferential surface 5 of the molybdenum wire 1 without going through the cutting process (,), they are necessarily made of smooth parts with no formation of flash. Since the material originally has a predetermined curvature, it can be easily rolled with a bending radius R (c).
従って、後述するように、フィラメントのレグ部の挿入
がきわめてスムーズなスリーブ9の挿入口10の形成部
を容易に得ることができる。Therefore, as will be described later, the insertion opening 10 of the sleeve 9 can be easily formed into which the leg portion of the filament can be inserted very smoothly.
次に、モリブデンテープ2をマンドレル8に巻きつける
工程(d)においては、径φ=0.25mmの円柱状マ
ンドレル8に巻きつける。このとき、モリブデンテープ
2の一対の切断端面4,4が互いに向き合うように丸め
て、マンドレル8設ける。Next, in the step (d) of winding the molybdenum tape 2 around the mandrel 8, the molybdenum tape 2 is wound around the cylindrical mandrel 8 having a diameter φ=0.25 mm. At this time, the mandrel 8 is provided by rolling the molybdenum tape 2 so that the pair of cut end surfaces 4, 4 face each other.
最後に、マンドレル8に設けたモリブデンテープ2をプ

よりも動供給する場合に、スリーブ9の合せ目の間隙1
1が、板厚tよりも大きいと、スリーブ9の合せ目に他
のスリーブの合せ目が噛み合ってしまい、自動供給作業
の妨げとなるからである。Finally, in a step (not shown) of press-molding the molybdenum tape 2 provided on the mandrel 8, the molybdenum tape 2 is molded with an inner diameter of φ=02 to 1.0 and a plate thickness of t=0.
A sleeve is obtained by press molding to a size of 0.07 to 0.20 m and a length t of 2 to 5 m. At this time, the gap 11. between the sleeve seams. That is, a pair of cut surfaces 4 of the molybdenum tape 2
.. The width of the gap created when 4 faces each other is the plate thickness t
When feeding dynamically, the gap 1 at the seam of the sleeve 9
1 is larger than the plate thickness t, the joints of other sleeves will mesh with the joints of the sleeve 9, which will impede the automatic feeding operation.
以上の説明から2本発明によれば、全くパリの発生がな

可能である。From the above explanation, two according to the present invention, it is possible to obtain a sleeve insertion opening that does not generate any flakes, so it is possible to easily obtain a high quality product, and furthermore, an etching process etc. is not required. Since the manufacturing process can be simplified, it is possible to provide a simplified manufacturing process with a good yield.
