Used by a department of defense contractor making countermeasure flares for the aircraft industry
-
Upper rams (2) have 3" x 12" F-R x 22" L-R bolsters
-
Lower rams (2) have 1.5" x 16" F-R x 10" L-R bolster
-
48" front to rear x 48" left to right footprint; 160" tall
-
A Parker high pressure lockable ball valve allows each cylinder to be mechanically turned on and locked off
-
The dual upper, down-acting rams: provide 55 tons of force each, are rigidly guided by 9" diameter x 20" long non-metallic bushings and have 20" of stroke
-
The dual lower, up-acting rams: provide 55 tons of force each, have an anti rotation guide bushing and 23" of stroke
-
Ram speeds: 45 IPM approach; 6 IPM pressing; 55 IPM return
-
Hydraulic power system with 60 gallon oil reservoir
-
The movement of each cylinder is independently controlled by its own directional control valves
-
Equipped with a TEFC motor mounted oil cooler
-
Eight (8) Neoprene/ nylon "bellows" style protective boots are provided for exposed ram slide areas
-
The extend pressing speed of each cylinder is independently controlled by its own flow control valve that will slow the fast approach speed
-
Pump pressure is controlled by a hand valve and is intended to be preset to obtain force to be applied to the powder
-
Digital pressure transducer/ switch is used to confirm the development of the force for valve sequencing and the initiation of the dwell under pressure feature
-
Each of the upper rams have an individual decompression feature
-
Two fully intrinsically safe NEMA 12 control panels with Allen Bradley 22mm Push Buttons and LEDs to meet class 2 Division safety standards
-
Siemens PLC control with 60 inputs and 44 outputs with inch and full-auto cycle modes
