    B/BS型的密封螺柱的標準及規格明細表
    密封螺母柱
    應用于需封閉底端的工作環境,有時候也叫防水螺柱或防水螺母柱
    密封螺母柱分為B型和BS型,B型為碳碳,BS為不銹鋼
    具體材質為:B-1214或1215, BS-SUS303
    硬度:B型密封螺柱為滲碳至HV400-500
    BS不銹鋼密封螺柱不作熱處理,所以它是不銹鋼棒本來的硬度,即HRB90(HV200)左右
    表面處理:B-默認為藍白鋅,BS-默認為不銹鋼本色 
    不銹鋼密封螺母柱
    BS不銹鋼密封螺母柱 材質;SUS303  左圖規格:BS-M4-2
    不銹鋼型的密封螺母柱采用SUS303生產,應于防銹的工作場合如鋁板銅板等,起密封防水作用,不建議用于不銹鋼板(雖然也能用)
    密封壓鉚螺母柱具有一個盲孔的內螺紋,頭部端類似于S型壓鉚螺母,壓鉚于板上形成一個有效內螺紋。
    采用自動車生產,由棒料一次車削→打孔→壓花→攻牙完成。

    B型密封螺柱的安裝方法、注事事項及其安裝示意圖
     

    1,密封螺柱的安裝方法如同左圖,視頻清楚的表達的它的安裝方法。

    2,密封螺柱的安裝方法結合了壓鉚螺母安裝與壓鉚螺柱安裝兩者的特點,而且安裝更簡單。什么叫兩者的特點?請看如下兩個鏈接
    這是:壓鉚螺母的安裝方法
    這是:壓鉚螺柱的安裝方法


    3,對板材的要求: 
    碳鋼薄板的硬度不要超過HRB70,雖然上面描述我們產品的硬度達HV400,但這是表面硬度,所以,薄板不可做熱處理
    不銹鋼板硬度不超過HRV80

    4,密封螺柱與板的材質的適配
    B型對應碳鋼薄板
    BS對應鋁板或銅板——沒錯,BS不適合壓不銹鋼板

    5,左圖中的壓機沖頭不是指沖床的沖頭,而是指壓鉚機的沖頭,由此引申的問題
    ——壓鉚機是什么? 請參考壓鉚螺母用什么設備壓?

    6,左圖中的工裝需要使用者自己做,它的設計比較簡單,工裝治具的孔做多大?——參考上面規格表中的“B”尺寸,不于小“B”尺寸
