液压机的应用及发展

on Application and Development of Hydraulic Press

液压机是一种利用液体静压力来加工金属、塑料、橡胶、木材、粉末等制品的机械。它是利用帕斯卡定律制成的利用液体压强传动的机械和用来传递能量以实现各种工艺的机器。现在液压机不仅可用于锻压成形,也可用于压装、压块、压板、打包和矫正等工艺。比较常见的工艺有压制工艺和压制成形工艺,比如:冲压、锻压、翻边、弯曲、压装、冷挤、校直、粉末冶金、薄板拉深等。

Hydraulic press is a kind of machinery which process metal, plastic, rubber, wood, powder products with hydrostatic pressure. It is made according to PASCAL＇s law and transmits under liquid pressure and it used to transmit energy to achieve various techinques. Now,it can not only be used to form forging hydraulic press but also can be used during the process of fitting press, briquetting, pressing plate, packaging, rectifying and otherwise. The common process includes pressing process and compression-molding process, such as： stamping, forging, flanging, bending, fitting press, cold extrusion, straightening, powder metallurgy, sheet deep drawing, etc.
