YD28 series Double action sheet forming Tensioning hydraulic press

FEATURES:

1. the four column tye press featuring compact arrangement and high price performance ratio；straight side structure press is with much high rigidity and precision,also eccentric load resistance performance.
2. Cartridge valve integrated unit equipped in hydraulic control system,with high relibility,durability.Oil leakage is avoided by means of proper piping and minmum hydraulic impact design.
3. Automatic lubrication to the guideway.
4. Electrical system controlled by imported PLC unit,with the features of compact,sensitivity,reliability and flexbility,reliable actions and easy maintenance are the features of the system based on relay control.
5. Stroke and pressure can be adjusted within specificed soope.
6. Working with presetting stroke or presetting pressure.Pressure can be held,time can be delayed and adjusted.
7. Drawing slide and blank holder and be joined together by location pins,thus the press can also be operated as single action hydraulic pres.
8. Working ways:adjusting,manual and semi-automatic.
