Four Columns Hydraulic Press Machine

four columns hydraulic press machine,hydraulic drive,separate control station Press Mechanical Construction

The press has four columns that tie together two stationary platens (the crown and the worktable). There is one sliding platen (beam) between the stationary platens. The main large hydraulic cylinder mounted on the top stationary platen is driving the sliding platen.

The main geometrical parameters of the press without control and hydraulic cabinet are:

Daylight between columns (L-R):   1600mm

Effective table size (F-B):        1600mm

Sliding platen stroke:               900mm

Maximum daylight:                   1600mm

Knock-out cylinder stroke:         400mm

2. Character

The main structure is three beams + four columns, with high rigidity

The hydraulic system adopts the cartridge valve integrated hydraulic block

The control panel/station is separating from the main structure, it's convenience for operating

Bi-Manual buttons operation to improve the security

Two types of working way: a. Stroke-set forming process b. Press-set forming process

Stroke and press can be adjusted according the practical situation

3. Press Mechanical Forces Specification

Maximum down-pressing force as applied to

sliding platen by the cylinders:          10000KN

Knock-out force:                                   2000KN

4. Press Hydraulic System Specification

Maximum hydraulic system pressure:                   25MPa

Hydraulic pump:                                     80 L x 2   

Hydraulic valve:                                    TAIFENG BRANF ISO Standard

Oil filtering system:                                 10micron replaceable filter

Sliding platen speed range:

No-load approach speed (down):                       100 mm/sec

Work speed (down):                                   5-7 mm/s

Return speed (up):                                   70 mm/sec

5. Press electrical and control system specification

Electric power requirement:                           380V/50Hz/3Phase

or as customer required

Motor power:                                                               30 KW x 2

Position control of moving platens:                      Proximity switches (SCHNIDER)

Push-buttons, relays, transformers:                       SIEMENS brand or similar brand

Safety of press operation:                             Bi-Manual buttons operation

 6.Description of press work cycle:

Initial position:

Sliding plate – all way up;

Step 1: Sliding plate down in no-load mode

Step 2: Sliding plate switch to work mode by proximity switch

Step 3: Sliding plate down in work mode till desired force achieved as measured by transducer

Step 4: Start timer when desired force achieved

Step 5: Upper sliding plate all way up after time on timer runs out

Repeat cycle

7. Miscellenious

Manual books:                       Full set of instruction books including mechanical,

                                   hydraulic and electrical schematics in English

Warranties:                         1-year manufacturers warranty for parts and labor
