To provide a manufacturing method of a snow melting nozzle which makes processing of the snow melting nozzle significantly easier.SOLUTION: Provided is a manufacturing method of a snow melting nozzle 1 having an upper part 1a to which a sprinkler member 2 for ejecting snow melting water is attached, and a lower part 1b to which a water pipe 3 through which snow melting water flows from underground is connected. The snow melting nozzle 1 is made by: a step of preliminarily forging a recess C of a predetermined depth in a bulge B provided on an upper part of a stainless steel round bar by a die D and a punch P of a die for preliminary forging; a step of precisely forging an inverted conical hollow portion 4 and a rotation-preventing convex portion 5 of the snow-melting nozzle 1 projecting radially to an outer surface by the die D having a recess and the punch P of the die for precision forging in the recess C at the time of preliminarily forging; and a cutting step of providing a seating surface 7 of an open end 4a of the hollow portion 4 to which the sprinkler member 2 is mounted, a flow hole 13 through which snow melting water flows, and a positioning portion 6 for restricting the vertical movement of the snow melting nozzle 1.SELECTED DRAWING: Figure 1
【課題】消雪ノズルの加工が極めて容易に行われる消雪ノズルの製造方法である。【解決手段】消雪水が噴出する散水部材２が装着される上部１ａと、地下からの消雪水の流通する導水管３が接続される下部１ｂとを有する消雪ノズル１の製造方法であって、前記消雪ノズル１は、ステンレス鋼材丸棒の上部に設けた膨出部Ｂに予備鍛造用の金型のパンチＰとダイＤにより所定の深さの凹みＣを予備鍛造成形する工程と、予備鍛造成形時の前記凹みＣに精密鍛造成用の金型のパンチＰと凹を有するダイＤにより逆円錐形状の空洞部４と、外側面に径方向に突出する前記消雪ノズル１の回り止め凸部５とを精密鍛造成形する工程と、前記散水部材２を装着する前記空洞部４の開口端４ａの座面７と、消雪水が流通する流通孔１３および前記消雪ノズル１の上下動を規制する位置決め部６とを設ける切削工程よりなる。【選択図】図１
