Description
本發明是有關於一種金屬件製程設備及製造方法,且特別是有關於一種在真空環境下可連續熔解金屬塊材的金屬件製程設備及製造方法。 The invention relates to a process equipment and a manufacturing method for metal parts, and more particularly to a process equipment and a manufacturing method for metal parts that can continuously melt metal blocks in a vacuum environment.
目前,真空感應熔煉氣體霧化(VIGA,Vacuum Induction-melting Gas Atomization)設備可用以製造金屬粉末。參考圖1,習知製造金屬粉末的方法如下:先以感應線圈99將位於一熔爐98內之金屬材料棒於真空環境下進行感應加熱,使該金屬材料棒熔化成熔湯91;然後,將該熔湯91倒入一承載坩堝92內;最後,該熔湯91以流動型態通過一熔湯輸送導管93並進入一噴嘴95後,被高速惰性氣體G沖擊霧化後並快速凝固成金屬粉末P。然而,在真空感應熔煉氣體霧化設備中,必須將金屬材料棒批次熔解後,才能進行霧化製粉。
At present, vacuum induction melting gas atomization (VIGA, Vacuum Induction-melting Gas Atomization) equipment can be used to produce metal powder. 1, the conventional method of manufacturing metal powder is as follows: first, a metal material rod located in a
電極感應熔煉氣霧化制粉(EIGA,Electrode Induction melting Gas Atomization)設備及電漿熔解霧化製程雖可將線材連續送料,但其線材表面品質非常講究,通常必須精過多次軋延、精抽及盤元,然後才能將線材熔解,以進行霧化製粉。然而,並非所有金屬材料均適合壓延、精抽及盤元。對於無常溫延展性的金屬材料,則無法使用盤元連續進料,導致無法連續生產。 Electrode Induction Melting Gas Atomization (EIGA) equipment and plasma melting and atomization process can feed the wire continuously, but the surface quality of the wire is very particular, usually it must be refined for multiple rolling and fine extraction. And then the wire can be melted for atomization and pulverization. However, not all metal materials are suitable for calendering, fine drawing and coiling. For metal materials with no ductility at room temperature, continuous feeding of disk elements cannot be used, resulting in continuous production.
中國大陸專利授權公告號CN 207222946U公開一種採用棒材連續進料生產球形粉末的設備,包括主軸、真 空腔體、自動夾頭、自動抓料裝置、原料熔棒、連接導向器、過渡導向器、直線驅動器、直線導向器、加熱裝置、原料熔棒盤、霧化器;所述主軸裝配於真空腔體上端;所述真空腔體包括主工作室、過渡門、置換門、過渡室、置換室,主工作室側依次設過渡室、過渡門、置換室、置換門,過渡室中設有原料熔棒盤,主軸下端設有自動夾頭,在主工作室垂直於原料熔棒盤中心位置的壁上設置自動抓料裝置。該專利文獻將原料熔棒的上端加工成內螺紋,下端加工成與上端內螺紋匹配的外螺紋。然後一支接一支送入真空腔體,以完成連續送料並連續霧化製粉之方式。雖然該專利文獻可採用棒材連續進料並連續霧化製粉,但是必須先將金屬材料均勻製備成上下端具有內外螺紋的原料熔棒,如此將增加製程成本。 The Chinese Mainland Patent Authorization Announcement No. CN 207222946U discloses a device for producing spherical powder with continuous feeding of rods, including a spindle, a real Cavity, automatic chuck, automatic gripping device, raw material melting rod, connecting guide, transition guide, linear drive, linear guide, heating device, raw material melting rod tray, atomizer; the spindle is assembled in a vacuum The upper end of the chamber; the vacuum chamber includes a main working room, a transition door, a replacement door, a transition room, and a replacement room.

The transition room is equipped with raw materials For the melting rod tray, there is an automatic chuck at the lower end of the main shaft, and an automatic grabbing device is installed on the wall of the main working room perpendicular to the center of the raw material melting rod tray. In this patent document, the upper end of the raw material melt rod is processed into internal threads, and the lower end is processed into external threads that match the upper internal threads. Then one by one is sent into the vacuum chamber to complete the continuous feeding and continuous atomization of powder. Although the patent document can adopt continuous feeding of rods and continuous atomization to make powder, the metal material must be uniformly prepared into raw material melt rods with internal and external threads at the upper and lower ends, which will increase the cost of the manufacturing process.
