    壓鉚螺母
    瀏覽: 發布日期:2018-09-10

    壓鉚螺母,又稱花柄螺母,通過壓鉚的方式固定于薄板,從下附的安裝視頻中可以看出,將薄板的預開孔置于螺母上方,通過壓機直接壓入薄板,從而在薄板上形成堅固的內螺紋.

    通過壓鉚螺母與薄板鉚接的這種方式,廣泛應用于機箱機柜\鈑金\及其它沖壓件,其行業遍及通信\汽車\網絡設備等。

    SP類的性能參數請參考:SP壓鉚螺母的標準
    壓鉚螺母的安裝方法

     
    安裝視頻:

    詳細的安裝方式請參考壓鉚螺母安裝方法

    就如同本頁上面的動畫視頻所示,將螺母置于工裝治具(下附工裝的設計方案圖)的孔內,壓鉚部分露出工裝平面,薄板孔對應螺母的鉚接口,采用壓鉚機壓入

    需要注意的是:

    1,壓鉚螺母置于薄板下方,壓機從薄板方向壓入.不可將壓鉚螺母置于薄板的上方通過直接壓入螺母的方式安裝,否則薄板將翹起

    ——這句話是什么意思呢?也就是說,不可以這種方式安裝,而應該以這種方式安裝,否則在壓鉚螺母與薄板接觸的地方薄板很有可能會翹起,尤其是應用于鋁板銅板等較軟的板。再來看一次壓鉚螺母的正確與錯誤安裝方式的對比示意圖

    2,如果不希望采用如下動面視頻動畫中的凹型工裝,也可采用簡易的頂針方式來固定壓鉚螺母,但壓鉚螺母依然是置于薄板下方,見頂針方式固定壓鉚螺母的安裝意圖

    3,不可使用沖床安裝壓鉚螺母,因為其行程是固定的,安裝力亦無法調試.如果一定要采用沖床,也請采用液壓沖床。

    以上方案作為實際作業中的理論參考,具體操作中跟據實際情況作適當調整,材質建議為模具鋼。我公司不能提供該配件的供應,工裝的制作并不是一個復雜的工程,一般上模會隨壓鉚機的廠商有配套供應,而用戶只需跟根據自己板材的形狀不同設計制作下模。

    關于壓鉚螺母的標準

    壓鉚螺母目前沒有對應的國標或國際標準,上面的規格表中的"型號TYPE"這一欄的“S”“CLS”“SP”指的是它型號的代號,雖不能稱之為標準,但業內約定俗成的將這種標注方式及它對應的參數作為一種行業標準。即:

    S:碳鋼壓鉚螺母

    CLS:不銹鋼壓鉚螺母

    SP:不銹鐵壓鉚螺母

    用戶在咨詢時只需這樣表達即可:如“S-M3-1 ZI(電鍍代號),或CLS M3-1等等。

    以下是從一組M3到M6的碳鋼鍍鋅的壓鉚螺母對比圖:

     

    壓鉚螺母標準

    關于非標準壓鉚螺母的訂制 

    除了以上所介紹的標準壓鉚螺母外,我公司可以根據客戶要求訂制各種非標準的壓鉚螺母,用戶可根據自己的需要自由選擇材質尺寸與螺紋規格——亦或是無螺紋就如同左圖。我們為眾多的用戶量身訂制過各種非標準的特殊的壓鉚螺母,具有豐富的設計與制造經驗。

    大圖賞析
    15倍放大壓鉚螺母效果圖:
    壓鉚螺母

    如你所見,每一顆螺母的花齒都打的鏗鏘有力,我們對齒模在模具中的位置作了重新設計以利于快速更換,從而保證了壓花的飽滿度、一致性及生產效率,這是我們的優勢所在。如你所知,在生產過程中齒模的損耗總是最快的,更換一組齒模,齒模本身沒多少錢,而時間成本卻不容小覷,所以有些工廠被動地降低了花齒的容忍度,故而市場上很多廠家的壓鉚螺母花齒總是有爛花現象,而我們卻不會。


    壓鉚螺帽

    由于長期生產壓鉚螺帽,我們的生產經驗更加豐富對質量要求更加嚴格。每批產品均經過嚴格的來料與生產檢驗,外協熱處理及電鍍每批產品均需測試與備樣.以CLS-M8為例,我們規定每個壓花輪生產2000支產品即更換以保證花齒清晰飽滿,為防止攻牙產生的斜牙與無牙,我們在入庫前全檢螺紋
