U型螺栓,即骑马螺栓,骑马螺栓英文名称为U-bolt,是非标准件,是形状为U形所以也称为U型螺丝,U型管卡,U型管夹,两头有螺纹可与螺帽结合,主要用于固定管状物如水管或片状物如汽车的板簧。那u型螺栓等紧固件标准就是规范,每个国家和部门都有自己的标准。目前,我们在平时的业务中最常用到的标准有以下几种:
GB—中国国家标准(国标)ANSI—美国国家标准(美标)
DIN—德国国家标准(德标)ASME—美国机械工程师协会标准
JIS—日本国家标准(日标)BSW—英国国家标准
GB—国家标准是我国众多标准中的一种,另外还有行业标准,专业标准和部门标准等。国家标准又分:GB(强 制性标准)和GB/T(推荐性标准)以及GBn(国家内部标准)等。我们平常看到的像GB30,GB5783等等都是强制性的标 准。
以上几种标准除了一些基本尺寸如头部对边、头部厚度等的不同以外,最主要的是螺纹部分的不同。GB、DIN、JIS 等的螺纹都有是以MM(毫米)为单位,统称为公制螺纹。另像ANSI、ASME等的螺纹是以英寸为单位的称为美标螺纹。除 了公制螺纹和美制螺纹外还有一种BSW—英制标准,其螺纹也是以英寸为单位,俗称惠氏螺纹。
公制螺纹是以MM(毫米)为单位,它的牙尖角为60度。美制螺纹和英制螺纹都是以英寸为单位的。美制螺纹的牙尖角 也是60度,而英制螺纹的牙尖角为55度。由于计量单位的不同,导致了各种螺纹的表示方法也不尽相同。例如像M16- 2X60表示的就是公制的螺纹。他的具体意思是表示该螺丝的公称直径为16MM,牙距为2MM,长度为60MM,又如: 1/4—20x3/4表示的就是英制的螺纹,他的具体意思是该螺丝的公称直径为1/4英寸(一英寸=25.4MM),在一英 寸上有20个牙,长度为3/4英寸。另外要表示美制螺丝的话一般会在表示英制螺丝的后面加上UNC以及UNF,以此来区别 是美制粗牙或是美制细牙。
在平时的内销业务中,我们最常遇到的标准是GB(国标)和DIN(德标)。
在非芳生产品方面,主要会接触到以下几种标准:GB30;GB5783;GB5782;GB52;GB6170;GB818;GB819;GB845 ;GB846;GB70;DIN912;DIN933;DIN931等。目前GB30(老国标)在标准书中已被GB5783(新国标)所代替。GB52( 老国标)在标准书中已被GB6170(新国标)所代替。
在1986年,我们国家对标准件制定了新标准,在业务中一般俗称为新标,使用最多的主要有GB5780、GB5781、 GB5782、GB5783、GB5784。GB5780为六角头粗杆半牙螺丝,其精度等级为C级产品,可用GB5782来代替(GB5782为六角 头粗杆全牙螺丝,其精度等到级为A级和B级。)GB5781为六角头全牙螺丝,精度等级为C 级产品。可用GB5783来代替( GB5783为六角头全牙螺丝,其精度等级为A级和B 级)。GB5784为细杆半牙的六角螺丝。
新标与老标的区别在于:M8、M10、M12、M14、M22系列的产品,在对边宽度上有所区别。除M22系列的新产品外,新 标产品M8、M10、M12、M14的头部对边比老标的对边要小1MM。分别为13、16、18、21MM ,而M22系列的新产品,新标 比老标的对边反而要大2MM,应特别注意。对于头部厚度,新标和老标之间略有差别,在要求不是非常严格的情况下可以 通用。
新标与德标的区别在于:M10、M12、M14、M22的产品规格,在对边宽度上有所差别。M10、M12、M14的头部对边新标 比德标要小1MM。而M22的新产品的,其头部对边比德标的对边宽度要大2MM ,其它的均可通用。
