</p> <p> <br /> </p> <p> 1、拉伸加工：使用壓板裝置，利用凸模的沖壓力，將平板材的一部分或者全部拉入凹模型腔內(nèi)，使之成形為帶底的容器。容器的側(cè)壁與拉伸方向平行的加工，是單純的拉伸加工，而對(duì)圓錐(或角錐)形容器、半球形容器及拋物線面容器等的拉伸加工，其中還包含擴(kuò)形加工。 </p> <p> <br /> </p> <p> 2、再拉伸加工：即對(duì)一次拉伸加工無法完成的深拉伸產(chǎn)品，需要將拉伸加工的成形產(chǎn)品進(jìn)行再次拉伸，以增加成形容器的深度。 </p> <p> <br /> </p> <p> <br /> </p><p> ①控制機(jī)械的運(yùn)動(dòng)，如內(nèi)燃機(jī)中的閥門彈簧片、離合器中的控制彈片等。 </p> <p> <br /> </p> <p> ②吸收振動(dòng)和沖擊能量，如汽車、火車車廂下的緩沖彈片、聯(lián)軸器中的吸振彈片等。 </p> <p> <br /> </p> <p> ③ 貯存及輸出能量作為動(dòng)力，如鐘表彈片、***中的彈片等。 </p> <p> <br /> </p> <p> ④用作測(cè)力元件，如測(cè)力器、彈片秤中的彈片等。彈片的載荷與變形之比稱為彈片剛度，剛度越大，則彈片越硬。按受力性質(zhì)，彈片可分為拉伸彈片、壓縮彈片、扭轉(zhuǎn)彈片和彎曲彈片，按形狀可分為碟形彈片、環(huán)形彈片、板彈片、螺旋彈片、截錐渦卷彈片以及扭桿彈片等。 </p> <p> <br /> 馬氏體相又脆，因此會(huì)容易出現(xiàn)開裂。</p><div
