i摘 要曲柄壓力機是通過曲柄滑塊機構將電動機的旋轉運動轉換為滑塊的直線往復運動，對胚料進行成行加工的鍛壓機械。曲柄壓力機動作平穩(wěn)，工作可靠，廣泛用于沖壓、擠壓、模鍛和粉末冶金等工藝。其結構簡單，操作方便，性能可靠。關鍵詞：壓力機，曲柄機構，機械制造ii3AbstractCrank pressure machine is pass crank a slippery piece organization to revolve electric motor conversion for slippery piece of straight line back and forth sport, Carries the formed processing to the semifinished materials the forging and stamping machinery. The crank press movement is steady, the work is reliable, widely uses in crafts and so on ramming, extrusion, drop forging and powder metallurgy. Its structure is simple ,the ease of operation , the performance is reliable .The coupling part uses the rigidity to transfer the key type coupling, the use service is convenient.Keywords: pressure
