Description
本發明係有關一種球閥體之加工裝置與加工方法,特別是指一種利用縮管模室將圓柱形管先形縮小內外管徑,再以另兩組模具分次沖壓,可適用較多尺寸的球閥體加工方法,並具有降低沖壓變形之優點。 The invention relates to a processing device and a processing method for a ball valve body, in particular to a method for shrinking a cylindrical tube into a shape of an inner and outer tube by using a shrinking tube mold chamber, and then stamping with two sets of other molds, which can be applied to more sizes. The ball valve body processing method has the advantages of reducing the stamping deformation.
習知的球閥體之製法,主要可參考中華民國專利第I344526號之『球閥體製造方法』,包含以下步驟:提供一肧管;對該胚管進行一擴管程序,用以擴大該肧管之內徑及外徑;放置該肧管於一下模具,其中該下模具具有一下半球模室及一下開口心軸,該肧管係放置於該下半球模室,且對準該下開口心軸;以一上模具朝向該下模具靠攏,進行一壓縮程序,於肧管之二端形成圓弧導角後停止壓縮,其中該上模具具有一上半球模室及一上開口心軸,該肧管係位於該上半球模室,且對準該上開口心軸;及持續以該上模具朝向該下模具靠攏,進行一最終壓縮程序,將該肧管壓製成該球閥體。 The method for manufacturing the ball valve body can be mainly referred to the "ball valve body manufacturing method" of the Republic of China Patent No. I344526, which comprises the steps of: providing a manifold; and expanding the tube to expand the fistula Inner diameter and outer diameter; placing the manifold in a lower mold, wherein the lower mold has a lower hemispherical mold chamber and a lower open mandrel, the manifold is placed in the lower hemispherical mold chamber, and the lower opening mandrel is aligned a compression process is performed with an upper mold facing the lower mold, and the compression is stopped after the arc ends are formed at the two ends of the manifold, wherein the upper mold has an upper hemispherical mold chamber and an upper open mandrel. A tube system is located in the upper hemisphere mold chamber and aligned with the upper opening mandrel; and the upper mold is continuously moved toward the lower mold to perform a final compression process, and the manifold is pressed into the ball valve body.
習用球閥體之製造方法產生以下問題: The manufacturing method of the conventional ball valve body produces the following problems:
(1)第一次擴管使管壁變薄,造成後續沖壓成型品質不穩定。 (1) The first expansion of the pipe makes the pipe wall thinner, resulting in unstable stamping forming quality.
(2)習用球閥體係先以於管體兩端沖壓出圓弧倒角狀,再進行下一沖壓球形程序,而從圓弧倒角的管體再沖壓成球狀, 其沖壓模對管狀胚進行沖壓時,該球狀沖壓模與管狀胚間仍有較長的直管壁尺寸差距,極易在沖壓後圓弧柱形管型之兩端進行沖壓力,使其兩端管面迅速產生收縮變形,造成其中段部位的直形管容易扭曲。 (2) The conventional ball valve system first punches out the arc chamfered at both ends of the pipe body, and then performs the next punching ball program, and then punches the ball from the circular chamfered tube into a spherical shape. When the stamping die presses the tubular embryo, there is still a long straight wall size difference between the spherical stamping die and the tubular embryo, and it is easy to apply pressure on both ends of the circular cylindrical tubular shape after punching, so that The tube faces at both ends are rapidly contracted and deformed, causing the straight tubes in the middle portion to be easily twisted.
(3)沖壓於肧管之二端形成圓弧導角時須分兩次沖壓,增加工時工序,如轉換沖壓定位不正,則導致在下一個沖壓球閥體程續易有有品質不良的瑕疵品產生。 (3) When stamping at the two ends of the manifold to form a circular arc guide angle, it is necessary to divide the stamping twice to increase the working time. If the conversion stamping position is not correct, it will result in the defective quality of the next stamping ball valve.
故,如何發展更好的球閥體加工方法,即是相關業界所要努力的方向。 Therefore, how to develop a better ball valve body processing method is the direction that the relevant industry should work hard.
