本考案は金属線の連続走行式熱処理装置において、金属線の表面状況を制御す るために加熱管の内部に不活性ガスを使用する際に、金属線相互の接続部など金 属線の断面変化に対応して開閉することにより、ガスシールと連続熱処理を同時 に行う自己封止型金属線挿入ノズルに関するものである。 The present invention is a continuous running type heat treatment apparatus for metal wires. When an inert gas is used inside the heating pipe to control the surface condition of the metal wires, the cross section of the metal wires such as the connection between metal wires is The present invention relates to a self-sealing metal wire insertion nozzle that simultaneously opens and closes in response to changes in gas sealing and continuous heat treatment.

従来、金属線に酸化スケールの制御や光輝焼鈍などの処理を施すために、加熱 管の内部に窒素、水素、アルゴンなどの雰囲気ガスを供給して、金属線の表面の スケールの厚みや金属線の光沢のある肌を抑制している。加熱管の内部の雰囲気 ガス中で鋼などの金属線を連続的に処理する連続走行式熱処理装置において、加 熱管の入口が開放されていると空気が吸い込まれてしまうので効果がない。この ため、外気が金属線挿入ノズル（以下単に挿入ノズルという）から加熱管の内部 へ浸入しないように、挿入ノズルの入口部をウエス（布切れ）などによりシール をした状態にして、金属線を加熱管へ送り込んで加熱処理する。しかし、先行す る金属線の端末と後続の金属線との接続部が挿入ノズルを通過する時には、作業 者が監視していてウエスなどのシールを取り除く必要がある。 Conventionally, in order to control the oxide scale and perform bright annealing etc. on the metal wire, an atmosphere gas such as nitrogen, hydrogen, and argon is supplied to the inside of the heating tube to measure the thickness of the scale on the surface of the metal wire and the metal wire. It suppresses the shiny skin of. In a continuous traveling type heat treatment apparatus for continuously treating a metal wire such as steel in an atmosphere gas inside a heating pipe, if the inlet of the heating pipe is opened, air will be sucked in, which is not effective. For this reason, in order to prevent outside air from entering the inside of the heating pipe from the metal wire insertion nozzle (hereinafter simply referred to as the insertion nozzle), the inlet part of the insertion nozzle should be sealed with a waste cloth and the metal wire should be sealed. It is sent to a heating tube for heat treatment. However, when the connection between the end of the leading metal wire and the trailing metal wire passes through the insertion nozzle, it is necessary for the operator to monitor and remove the seal such as waste.
【０００３】 図６に示すように、従来の連続走行式熱処理装置では、加熱炉２の内部に配設 される加熱管３は入口端を、加熱炉２の入口部から外部へ突出され、加熱管３の 入口端に接続された挿入ノズル３４へ、雰囲気ガス供給用ノズル１５からガスが 流入する状態で、金属線１１が加熱管３へ連続的に送り込まれる。先行する金属 線１１の端末は後続の金属線１３と適当な手段により接続される。金属線相互の 接続部１２が挿入ノズル３４を円滑に通過するには、挿入ノズル３４の内径（円 筒部６の内径）は金属線１１の外径の３倍以上にしないと支障が生じる。As shown in FIG. 6, in the conventional continuous traveling type heat treatment apparatus, the heating pipe 3 disposed inside the heating furnace 2 has its inlet end projected from the inlet portion of the heating furnace 2 to the outside and is heated. The metal wire 11 is continuously fed into the heating pipe 3 in a state where the gas flows from the ambient gas supply nozzle 15 into the insertion nozzle 34 connected to the inlet end of the pipe 3. The end of the preceding metal wire 11 is connected to the following metal wire 13 by any suitable means. In order for the connecting portion 12 of the metal wires to pass through the insertion nozzle 34 smoothly, there will be a problem unless the inner diameter of the insertion nozzle 34 (the inner diameter of the cylindrical portion 6) is at least three times the outer diameter of the metal wire 11.
【０００４】 挿入ノズル３４の内径を金属線１１の外径の３倍にすると、雰囲気ガス供給用 ノズル１５から供給される雰囲気ガスが挿入ノズル３４から洩れ、または外気が 挿入ノズル３４から浸入するので、挿入ノズル３４の入口部にウエスなどを詰め て空気の浸入を防止する必要がある。しかし、金属線相互の接続部１２が挿入ノ ズル３４を通過するのを監視していないと、ウエスが挿入ノズル３４や加熱管３ の内部へ引き込まれ、加熱管３が詰り、断線の原因になる。If the inner diameter of the insertion nozzle 34 is made three times as large as the outer diameter of the metal wire 11, the atmospheric gas supplied from the atmospheric gas supply nozzle 15 leaks from the insertion nozzle 34 or the outside air enters from the insertion nozzle 34. It is necessary to prevent the infiltration of air by filling the inlet of the insertion nozzle 34 with a waste cloth or the like. However, if the connection 12 between the metal wires is not monitored to pass through the insertion nozzle 34, the waste cloth is drawn into the insertion nozzle 34 or the inside of the heating tube 3 and the heating tube 3 is clogged, causing a disconnection. Become.

本考案では挿入ノズルの入口部に縦割りされた複数の分割体からなる円錐形の コマを配設し、該コマがばねの力により金属線と挿入ノズルの間の隙間を閉鎖す るように構成される。金属線相互の接続部が到来すると、コマはばねの力に抗し て後退し、同時に分割体が相互に径外方へ拡開し、接続部の円滑な通過を促す。 接続部が通過した後は、コマは再びばねの力により径内方へ縮閉する。この時、 コマはばねの力により挿入ノズルの円錐孔に沿つて軸方向へ移動する。 In the present invention, a conical top composed of a plurality of vertically divided divisions is arranged at the inlet of the insertion nozzle, and the top closes the gap between the metal wire and the insertion nozzle by the force of the spring. Composed. When the connecting portion between the metal wires arrives, the coma retracts against the force of the spring, and at the same time, the split bodies expand radially outwardly from each other, facilitating smooth passage of the connecting portion. After the connection portion has passed, the top again contracts radially inward due to the force of the spring. At this time, the top moves axially along the conical hole of the insertion nozzle due to the force of the spring.

図１は本考案に係る自己封止型金属線挿入ノズルの概略構成を示す側面断面図 である。挿入ノズル４は加熱炉２の入口部から外部へ突出される加熱管３に外嵌 結合される。挿入ノズル４は基端側の円筒部６へ雰囲気ガス供給用ノズル１５を 突出される。挿入ノズル４は先端側の先細りの円錐孔４ｂに、縦割りされた複数 の分割体からなるコマ５を収容され、かつ挿入ノズル４の段部８とコマ５との間 に介装したばね２７により入口端側へ付勢係合されている。すなわち、コマ５は 互いに接して環状をなし、金属線１１を通過させる通孔５ａを出口側に、金属線 相互の接続部１２を円滑に導入案内する円錐孔５ｂを入口側にそれぞれ備えてい る。 FIG. 1 is a side sectional view showing a schematic structure of a self-sealing metal wire insertion nozzle according to the present invention. The insertion nozzle 4 is externally fitted and coupled to the heating pipe 3 which is projected from the inlet of the heating furnace 2 to the outside. The insertion nozzle 4 has an ambient gas supply nozzle 15 protruding from the cylindrical portion 6 on the base end side. The insertion nozzle 4 accommodates a top 5 composed of a plurality of vertically divided divisions in a tapered conical hole 4b on the front end side, and a spring 27 interposed between the step 8 of the insertion nozzle 4 and the top 5. Is biased toward the inlet end side by. That is, the top 5 is in contact with each other to form an annular shape, and has a through hole 5a for passing the metal wire 11 on the outlet side and a conical hole 5b for smoothly introducing and guiding the connecting portion 12 of the metal wires on the inlet side. .
【０００９】 先行する金属線１１と後続する金属線１３とは、例えば針金などにより互いに 接続され、金属線相互の接続部１２が挿入ノズル４へ挿入される時、接続部１２ が円錐孔５ｂに当り、コマ５をばね２７の力に抗して左方へ押す。コマ５は挿入 ノズル４の円錐孔４ｂに沿つて移動し、同時に接続部１２により拡開され、接続 部１２を通孔５ａへ円滑に導入する。The preceding metal wire 11 and the following metal wire 13 are connected to each other by, for example, a wire, and when the connecting portion 12 of the metal wires is inserted into the insertion nozzle 4, the connecting portion 12 is inserted into the conical hole 5b. Then, the top 5 is pushed to the left against the force of the spring 27. The top 5 moves along the conical hole 4b of the insertion nozzle 4, and at the same time is expanded by the connecting portion 12 so that the connecting portion 12 is smoothly introduced into the through hole 5a.
【００１０】 接続部１２がコマ５を押し拡げて通過する時、コマ５はばね２７と円錐孔４ｂ の相互作用により互いに径内方へ押されているので、挿入ノズル１５から挿入ノ ズル４へ供給される雰囲気ガスが、コマ５の隙間から外部へ洩れる量、または外 気が挿入ノズル４へ流入する量は最小限に抑えられる。接続部１２がコマ５を通 過すると、ばね２７の力によりコマ５が円錐孔４ｂに沿つて右方へ押されると同 時に、コマ５は互いに縮閉し、金属線１３を覆い、雰囲気ガスがコマ５の通孔５ ａの隙間から洩れ、または外気が挿入ノズル４へ浸入するのを抑える。When the connecting portion 12 pushes and spreads the top 5, the top 5 is pushed radially inward by the interaction of the spring 27 and the conical hole 4 b, so that the insertion nozzle 15 moves to the insertion nozzle 4. The amount of ambient gas supplied to the outside through the gap between the tops 5 or the amount of ambient air flowing into the insertion nozzle 4 is minimized. When the connecting portion 12 passes through the top 5, the top 5 is pushed rightward along the conical hole 4b by the force of the spring 27, and at the same time, the tops 5 contract and close to each other, cover the metal wire 13, and remove the atmosphere gas. Suppresses the leakage of air from the gap of the through hole 5a of the top 5 or the invasion of outside air into the insertion nozzle 4.

The flange 23c of the inner cylinder 23 is abutted against the end of the connecting cylinder 22, and is fastened by a plurality of bolts 24. The inner cylinder 23 has a cylindrical portion 23a at the outlet end and a divergent conical portion 23b at the inlet end. The outer cylinder 26 is screwed into the inner cylinder 23, and the insertion nozzle 4 having the tapered conical hole 4b is screwed into the screw portion 4a of the outer cylinder 26. The top 5 made of a divided body is fitted in the conical hole 4b, and is urged to the right by a coiled spring 27 interposed between the end of the inner cylinder 23 and the top 5. The insertion nozzle 4 and the top 5 are configured to be exchangeable according to the outer diameter of the metal wire 11 to be heat-treated. As shown in FIGS. 4 and 5, the top 5 is composed of four divided bodies, and usually has an annular shape that is in contact with each other and has a through hole 5a through which the metal wire 11 passes. At the inlet end of the top 5, a conical hole 5b communicating with the through hole 5a is formed. The outer peripheral surface of the top 5 forms a conical surface 5c and is engaged with the conical hole 4b of the insertion nozzle 4.
【００１２】 図５に示すように、金属線相互の接続部１２が通過する時、分割体は接続部１ ２に押されて互いに径外方へ離隔するので通孔５ａが拡開し、接続部１２の円滑 な通過を許す。金属線相互の接続部１２が通過した後は、ばね２７の復元力によ りコマ５は円錐孔４ｂに沿つて元の位置へ戻される。コマ５は２分割体または３ 分割体でも、ほぼ同様の作用・効果が得られる。As shown in FIG. 5, when the connecting portions 12 of the metal wires pass through, the divided bodies are pushed by the connecting portions 12 and are spaced radially outwards from each other, so that the through holes 5a are expanded and the connecting portions are connected. Allow smooth passage of section 12. After the connecting portion 12 between the metal wires has passed, the restoring force of the spring 27 causes the top 5 to return to its original position along the conical hole 4b. Even if the top 5 is a two-divided body or a three-divided body, almost the same action and effect can be obtained.
