棒の製造装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an apparatus for manufacturing a glass rod used as a welding material or filler for a ferrite material when manufacturing a ferrite magnetic head or the like.
［従来の技術］

円柱状のガラス製のロッドプリフォーム１を入れて加熱
する。[Prior Art] Conventionally, when manufacturing ferrite magnetic heads, small diameter glass rods have been used as welding materials for ferrite materials. This conventional glass rod manufacturing apparatus is shown in FIG. A cylindrical glass rod preform 1 manufactured in advance in a separate device is placed in an electric furnace 2 consisting of an annular preheater 3 and an annular heater 4 below it and heated.
上方の予熱ヒータ３はガラスを軟化させるためのもので
あり、下方にある加熱ヒータ４はその軟化したガラスを
半溶融にするためのより高温のものである。The upper preheater 3 is for softening the glass, and the lower heater 4 is for heating the softened glass to a semi-molten state.
加熱ヒータ４によって半溶融の状態とされたガラスは、
自重で細くなりながら下方に垂れ下がり、自からの表面
張力で断面が略円形の小径のガラス棒５となってゆく。The glass made into a semi-molten state by the heater 4 is
It hangs downward while becoming thinner due to its own weight, and becomes a small diameter glass rod 5 with a substantially circular cross section due to its own surface tension.
この半溶融の状態のガラスは下方に行くにつれて冷却さ

用ローラ６．７によって下方へ引き出される。この断面
円形のガラス棒５は、フェライト磁気ヘッド等の製造時
に、フェライトブロックのつき合せ部に溶着材等として
使用される。This semi-molten glass is cooled as it goes downward, and the solidified glass rod 5, which has a circular cross section and a small diameter, is pulled downward by a pair of transfer rollers 6.7. This glass rod 5 having a circular cross section is used as a welding material or the like at the mating portion of ferrite blocks during the manufacture of ferrite magnetic heads and the like.
このフェライトブロックのつき合せ部は、溶着材を載せ

き合せ部の溶着材を載せる窪みは断面が７字形をしてお

棒１０を載置した方が作業性及び歩留り率が良い。In the abutting portion of the ferrite block, the recess on which the welding material is placed does not necessarily have a circular cross section. For example, as shown in FIG. 6, the recess on which the welding material is placed at the mating part of the ferrite block 8.9 has a 7-shaped cross section, and a triangular prism glass rod 10 that matches the V-shape is inserted into this recess. The workability and yield rate are better if it is mounted.

。Furthermore, as shown in FIG. 7, when filling the grooves of the ferrite block 11 with glass, if the cross section of the glass rod is circular, the stability is poor (it will move). It is easier to work if the prismatic glass rod 12 is mounted.
その他に、断面が楕円であるものや断面が菱形やその他
の特殊な断面形状のもの等、用途に応じた断面形状のガ
ラス棒があれば便利である。In addition, it would be convenient to have a glass rod with a cross-sectional shape suitable for the purpose, such as one with an elliptical cross-section, a diamond-shaped cross-section, or another special cross-sectional shape.

。[Problems to be Solved by the Invention] However, in the conventional manufacturing apparatus shown in FIG. A rod is something that cannot be manufactured. For this reason, glasses with triangular or square cross sections were manufactured by cutting large blocks of glass with a diamond cutter. Manufacturing by this cutting is
The problem was that it was too expensive. Furthermore, if the cross section is a special shape such as an ellipse or a trapezoid, there is a problem in addition to the cost problem that it is impossible to obtain a uniform cross section.
