Salient Features of Hydraulic Presses

Salient Features of Hydraulic Presses Points : Salient Features of Hydraulic Presses

1. These presses provide fast approach slow’ pressing and fast return speeds. The change in speed can be manually preset to take place at any point of the stroke with the help of limit switches / proximity switches.
2. The frame is fabricated by ultrasonically tested quality profiles and plates of suitable thickness to with stand the load and longer life of the press. The frames are stress-relieved.
3. Maximum frame rigidity is achieved through computer aided frame design and finite element analysis.
4. Extra long, precision machined and hardened guides to fade slides offer exceptional accuracy and alignment which further reduced to wear.
5. In blanking or punching hydraulic presses a damping system can be fitted. This effectively reduces breakthrough noise and tool wear normally generated by such operations.
6. The low noise hydraulic power pack unit is designed as per international practices and assembled with internationally reputed make components. The presses are designed as per ISI guidelines, hence standard seals, bushes are used.
7. “Programmable logic controls” (PLC) is provided in our presses of international standard make i.e. ABB/Allen-Bradley/Siemens/Telemacqnice/Keyence, offering maximum production flexibility and full compatibility with international standards.
8. Precise machining of the structural membrane is done after normalizing to get the required accuracies like parallelism between platen and bed and right angularity. between bed and the moving platen.
9. ‘Lubrication: Ram slides/guides/guide bushes are lubricated from a centralized lubrication arrangement.
10. Moving platen: It is a fabricated, heavy duty, tested welded plate construction for highest stiffness under heavy loads. The whole platen is stress-relieved after welding. ‘T’ slots provided in the platen are as per DIN standards.
11. Hydraulic or mechanical ejector pins to operate from inside the ram is also provided as optional on request or depending on the application.
12. Die transfer rails or bolster, sliding arrangement is also provided as optional in front side of the press for heavy tools applications.
