組合五金家具螺絲的常識
- 2019-01-17 -

                         組合五金家具螺絲的常識

    以下幾項具體介紹了組合螺絲的常識:


    1.組合螺絲成型自攻螺絲A,AB, B, BP, C等型式現在已逐步為組合五金家具螺絲滾成自攻螺絲所代替,故在新規劃中不主張運用. AB, B, BP不相同處僅在尾部形狀, AB有一個組合螺絲錐尾,


    2.B有一個鈍尾, BP有一個無組合螺絲之錐尾,尖尾基地進入預鉆孔并開始使組合螺絲成型.組合螺絲切削自攻螺絲有BF, BP, D, F, G及T等辦法, BF, BP為寬組合螺絲, 其他為機械組合螺絲.


    3.辨識字符不相同點在于其切削尾.每一種切削尾都有一個能夠搜集切削下廢料之形狀, 假定自攻螺絲旋入盲孔( 不貫穿之孔 ),則其碎片將殘留且密封于孔底.

    4.但如攻入貫穿孔時, 則廢料將掉在工件的另一邊. 所以在挑選本型式自攻螺絲時必需考慮及此, 廢料可能會構成污染, 掉進工作中之零件或使電子基板無法運作.


    5.一切組合螺絲滾成自攻螺絲均為機械組合螺絲, 與英美一起組合螺絲粗牙相同,請參閱SAE J81規則.公制組合五金電器螺絲請參閱SAE J1237及DIN7500規則.


    新規劃的組合螺絲組件的特征。關于典型結構的功用以及缺點,自行規劃了一種組合螺絲組件來代替正本的典型結構。新規劃的組合螺絲組件與典型的起浮螺母組件功用相同,接口規范與原結構保持共同。首要在結構上做了一些改進,將原結構中的螺釘螺母改為組合螺絲結構,組合螺絲與固定板選用增強尼龍材料,壓鑄成型;起浮螺母塊選用規范方螺母。


    裝置時,只需將起浮螺母塊放入固定板中心的凹槽內,并靠近機柜飛邊,然后用手壓入組合螺絲及芯棒即可完成裝置。新組件中起浮螺母塊依托固定板上的凹槽來限位并供給起浮空間,與原組件的原理和功用共同。柳釘新組件關于原組件的缺點進行了美妙改進,使其具有了新的特征
