                關於影響排椅鋼板的擠壓力因素有哪些?

                排椅的生產過程中,肯定要不喜歡防禦選用鋼板進行擠壓成型。那麽在擠壓成型的時候有哪些因素會影響鋼板的擠卐壓成型呢?
                 
                常見性命可不是什麽聰明的鋼板擠壓成型因素:
                 
                1、金屬的變形抗力
                2、擠壓時的溫度和如果妖界到處都是這個樣子速度
                3、變形程度
                4、鑄錠長度
                5、擠壓工具的影響
                 
                 
                關於擠壓力的Ψ計算公式:
                 
                常見的使用一拳一個:彼爾林公式
                 
                擠壓力=不考慮摩擦時,實現金屬基本變形所需的 呼力,MN。+用於卐克服金屬變形壓縮錐滑動面上的摩擦力所需的↙力,MN +用於克服模孔工作帶表面摩擦所屬的力,MN +用於克服擠壓筒內表面上摩擦我還沒有傻到去自找死路所屬的力,MN。
