target="_blank">鉚螺母</a>與鉚件安裝前的注意事項外，我們需要了解鉚螺母的承載能力： </h3> <p> M3-M12的鉚螺母都是由低碳鋼經(jīng)冷擠壓制作而成，因此對它的選用與低強(qiáng)度螺母類似，但它的螺紋強(qiáng)度高于6級，低于8級。鉚螺母用在有熱源的部位時，其溫度應(yīng)低于500℃，同時應(yīng)考慮承載能力相應(yīng)降低，使用者可通過試驗來決定。 </p> <h3> 為了延長鉚螺母的使用壽命，我們使用前需要將其清潔干凈： </h3> 被鉚板面不得有油污，包括已油漆或表面磷化處理。 <h3> 具體的清潔方法： </h3> <p> 鉚螺母表面涂油處理：有的使用廠家用的是旋轉(zhuǎn)汽動鉚槍，由于該槍在工作時，槍栓必須要加油用以減少與鉚螺母螺紋的摩擦陰力，因此要求鉚螺母生產(chǎn)廠對產(chǎn)品進(jìn)行上油處理，這樣就為使用廠家在安裝使用時帶來了一定的好處，但卻犧牲了鉚螺母與工件間的預(yù)緊扭矩。最好是邊使用邊給槍栓點油。根本的解決辦法應(yīng)該是使用氣液聯(lián)動拉鉚槍，因為這樣鉚槍在鉚接時，槍栓不會旋轉(zhuǎn)，而是槍頭自行收縮。
