          怎樣從規格上選擇合適的壓力機呢


          作者:admin時間:2019-12-06

          壓力機的沖壓設備類型較多,其剛度、精度、用途各不相同,而根據壓力機的規格不同,我們應該怎樣從規格上選擇合適的壓力機呢?

          ① 壓力機的公稱壓力必須大于沖壓工藝力。但對工作行程較長的工序,不僅僅是只要滿足工藝力的大小就可以了,必須同時考慮滿足其工作負荷曲線才行。

          ②壓力機滑塊行程應滿足制件在高度上能獲得所需尺寸,并在沖壓工序完成后能順利地從模具上取出來。對于拉伸件,則行程應在制件高度兩倍以上。

          ③壓力機的行程次數應符合生產率的要求。

          ④壓力機的閉合高度、工作臺面尺寸、滑塊尺寸、模柄孔尺寸等都要能滿足模具的正確安裝要求.
