HLPG Series Closed-door Type Double Crank Precision Steel Frame Punch Press named HLPG Series Closed-door Type Double Crank Precision Steel Frame mechanical press.

HLPG series are special for the stator and rotator high speed line,suitable for high speed hole forging.These machines own high rigidity and high strength frame,footstock,poster and bolster.

■  A standard feature of DYNAMIC BALANCING DEVICE is employed to counterbalance eccentric thrust generated from crankshaft rotation and slide movement.This may ensure better precision lamination and longer service life of high quality tools can therefore be secured because of substantial reduction of press frame vibration.

■  A ground high quality alloy steel crankshaft has two wide con-rods closely supported by four main frame bronze bearings.The two con-rods allow the use of long tools with different operating stations and allow for off-center loading.

■  The plunger guide design eliminates the change in guide clearances between the plunger and guide sleeve caused by the different expansion rates of the crown and slide in the horizontal plane.The proper connecting rod plunger  clearance is maintained thus increasing resistance from front & to back loads created by the rotation of the eccentric shaft.

■  High predision eight-way bearing guides,free from backlash with permanently incorporated roller circulating elements guide the slide accurately across the whole stroke.

■  Hydraulic SLIDE ADJUSTMENT LOCKING DEVICE is employed as standard to eliminate clearances inside the slide adjustment drive system on a regular basis to guarantee the consistency of slide bottom dead center.

■  High speed,high precision,change gear type,cam indexing roller feed is provided for a wide ranges of feed pitch.

■  Fully stress-relieved cast iron frame under hydralulically pre-stressed the rod construction ensures high speed laminating precision and rigidity.

■  A neoprene resilient cushion designed to provide the best combination of isolation effectiveness and machine stability.The cushions are designed and designed and compouned to have a long effective life and to be resistant to oils and  lubricants.(optional accessory)
