    壓鉚螺釘,其描述方式為FH,不銹鋼的壓鉚螺釘型式為FHS,材持為SUS304。壓鉚螺釘應于機箱機箱鈑金類的薄鈑,安裝簡單方便。在薄板上預沖一個鉚壓孔(孔尺寸參考下面的技術資料),將壓鉚螺釘插入孔內,利用沖床或壓鉚機施力平壓頭部,壓鉚螺釘的齒會冷嵌壓入薄板內,從而形成一個牢固的螺紋連接副且永久固定在薄板上。

    壓鉚螺釘的安裝方法,及其注意事項
     
     


    本頁上面的安裝示意圖已通過動畫的方式簡要表達了壓鉚螺釘的安裝方法。為了看了更清楚一點,我們將它放大了一些,如上圖。 

    1,先將壓鉚螺釘放入預先準備好的工裝設備中,這具工裝已裝預留有孔,孔的直徑大于螺釘的螺紋外徑。

    2,根據產品規定的安裝力施壓安裝到位。這里要注意的是在施壓中,產品頭部排出的板料需要平穩、均勻流入筋鍵周邊和容槽內。
    所謂“規定的安裝力”請參考本頁下面列出的壓鉚螺釘安裝力推出力扭出力等標準。

    3,安裝結束之后,安裝板外表平穩,裝置作用牢靠,并且商品具有接受高扭出力和高推出力的功能。 
    在整個安裝過程中,螺栓裝置在1.51mm的板料或高于該厚度的薄板中時,下模上需有一個容得下螺栓的通孔,而在板料厚度小于1.51mm的情況下,下模需求加工一個沉孔,以便螺栓頭部進入下模而使之順暢壓入板料。

    4,前面有提及,鍍鋅板或冷扎板硬度不高于HRB70,不銹鋼板不高于HRB80.

    5,值得一提的是,SUS304不銹鋼板并不適于用FHS的不銹鋼螺釘,FHS不銹鋼螺釘其實適用于鋁板和銅板的,304不銹鋼板用FH4類的不銹鐵壓鉚螺釘更合適。因為FH4不銹鐵螺釘經過真空熱處理后硬度可達HRC45以上。
    我們上面的價格表或規格表中并未列出FH4這類螺釘,但是可以供應。

    螺釘鉚接安裝好之后的測試標準如下

    壓鉚螺釘的規格及其表示方法
    上面的表格中列出了所有常用的壓鉚螺母規格,小到M2.5-6大至M8-35,更大規格我們沒有列出,可根據客戶要求訂制
    壓鉚螺釘的規格描述規則示例:
    FHS-M6-15
    FHS-表示不銹鋼壓鉚螺釘,而不是碳鋼的FH
    M6-螺紋
    15-長度
    ZU-電鍍代號,藍鋅
    用動畫來表示更加形象一點:

    FHS SUS304   本色
    FH4 SUS410 真空淬火 HV450-520 本色
    壓鉚螺釘的使用說明
    1、FH壓鉚螺釘(FHS不銹鋼壓鉚螺釘)系列產品中,FH的材料為中碳鋼,經過淬火后表面處理,用戶可根據需要按表中型號選擇訂貨,也可以特別要求訂制。  
    2、選用壓鉚螺絲時,必須根據所用材料厚度,其板材的要求,低碳鋼版材應當必須小于70HRB,不銹鋼板材必須小于80HRB。   
    3、加工板材孔必須對應表中給定值,按照0-0.075mm的公差加工,建議沖孔。   
    4、安裝壓鉚螺釘時必須通過壓鉚來實現,其壓力根據板材及螺釘頭部尺寸而變化,不可用沖床沖壓安裝。
