u型螺栓,即騎馬螺栓,騎馬螺栓英文名稱為U-bolt,是非標準件,是形狀為U形所以也稱為U型螺絲,U型管卡,U型管夾,兩頭有螺紋可與螺帽結合,主要用于固定管狀物如水管或片狀物如汽車的板簧。那u型螺栓等緊固件標準就是規范,每個國家和部門都有自己的標準。目前,我們在平時的業務中最常用到的標準有以下幾種:
GB—中國國家標準(國標)ANSI—美國國家標準(美標)
DIN—德國國家標準(德標)ASME—美國機械工程師協會標準
JIS—日本國家標準(日標)BSW—英國國家標準
GB—國家標準是我國眾多標準中的一種,另外還有行業標準,專業標準和部門標準等。國家標準又分:GB(強 制性標準)和GB/T(推薦性標準)以及GBn(國家內部標準)等。我們平??吹降南馟B30,GB5783等等都是強制性的標 準。
以上幾種標準除了一些基本尺寸如頭部對邊、頭部厚度等的不同以外,最主要的是螺紋部分的不同。GB、DIN、JIS 等的螺紋都有是以MM(毫米)為單位,統稱為公制螺紋。另像ANSI、ASME等的螺紋是以英寸為單位的稱為美標螺紋。除 了公制螺紋和美制螺紋外還有一種BSW—英制標準,其螺紋也是以英寸為單位,俗稱惠氏螺紋。
公制螺紋是以MM(毫米)為單位,它的牙尖角為60度。美制螺紋和英制螺紋都是以英寸為單位的。美制螺紋的牙尖角 也是60度,而英制螺紋的牙尖角為55度。由于計量單位的不同,導致了各種螺紋的表示方法也不盡相同。例如像M16- 2X60表示的就是公制的螺紋。他的具體意思是表示該螺絲的公稱直徑為16MM,牙距為2MM,長度為60MM,又如: 1/4—20x3/4表示的就是英制的螺紋,他的具體意思是該螺絲的公稱直徑為1/4英寸(一英寸=25.4MM),在一英 寸上有20個牙,長度為3/4英寸。另外要表示美制螺絲的話一般會在表示英制螺絲的后面加上UNC以及UNF,以此來區別 是美制粗牙或是美制細牙。
在平時的內銷業務中,我們最常遇到的標準是GB(國標)和DIN(德標)。
在非芳生產品方面,主要會接觸到以下幾種標準:GB30;GB5783;GB5782;GB52;GB6170;GB818;GB819;GB845 ;GB846;GB70;DIN912;DIN933;DIN931等。目前GB30(老國標)在標準書中已被GB5783(新國標)所代替。GB52( 老國標)在標準書中已被GB6170(新國標)所代替。
在1986年,我們國家對標準件制定了新標準,在業務中一般俗稱為新標,使用最多的主要有GB5780、GB5781、 GB5782、GB5783、GB5784。GB5780為六角頭粗桿半牙螺絲,其精度等級為C級產品,可用GB5782來代替(GB5782為六角 頭粗桿全牙螺絲,其精度等到級為A級和B級。)GB5781為六角頭全牙螺絲,精度等級為C 級產品??捎肎B5783來代替( GB5783為六角頭全牙螺絲,其精度等級為A級和B 級)。GB5784為細桿半牙的六角螺絲。
新標與老標的區別在于:M8、M10、M12、M14、M22系列的產品,在對邊寬度上有所區別。除M22系列的新產品外,新 標產品M8、M10、M12、M14的頭部對邊比老標的對邊要小1MM。分別為13、16、18、21MM ,而M22系列的新產品,新標 比老標的對邊反而要大2MM,應特別注意。對于頭部厚度,新標和老標之間略有差別,在要求不是非常嚴格的情況下可以 通用。
新標與德標的區別在于:M10、M12、M14、M22的產品規格,在對邊寬度上有所差別。M10、M12、M14的頭部對邊新標 比德標要小1MM。而M22的新產品的,其頭部對邊比德標的對邊寬度要大2MM ,其它的均可通用。
