曲柄剪板机全套毕业
摘要
曲柄剪板机是通过曲柄滑块机构将电动机的旋转运动转换为滑块的直线往复运动，对胚料进行成型加工的锻压机械。曲柄剪板机动作平稳，工作可靠，广泛用于冲压，挤压。锻模和粉末冶金等工艺。其结构简单，操作方便，性能可靠。
关键词：剪板机，曲柄机构，机械制造
Abstract
Crank 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 case of operation, the performance is reliable. The couping part uses the rigidity to transfer the key type coupling, the use service is convenient.
Key word : pressure machine, crank organization, machine manufacturing
