Classification of Hydraulic Machine
From type of structure, hydraulic press machine could be classified to single column, four columns, and framed hydraulic press machine. This 3 types take up more than 95% market shares of hydraulic machine. Single column hydraulic machine could be classified into whole body and combination body structure.During the working period, due to the deformation of body, there will be certain angle appering between side block and operating platform, thus it can be applied to low level precision occasions like: press mounting, plates compression,straightening etc.
Four-column hydraulic press machine applies 4 pillars to connect the upper beam and lower beam. It is of compact structure and low cost, so it could be widely used.
Framed hydraulic press machine applies welded frame structure substituting for 4 pillar columns. It is of high level precision,however,the price is higher than the four-column machine. It can be used in high level precision areas like: SMC molding, stamping of sheet metal, metal precise molding etc.
According to different demands,there are other special structures of hydraulic machines like: two-column, multiway,horizontal type etc. |
