Description

WHAT IS ADVANTAGE?

connecting-rods

Eliminate one of the largest maintenance costs of a stamping press: the wrist pin slide connections

Withstands the rigors of heavy progressive die stamping by providing increased surface area to transmit high forces

overload protector

Hydraulic Overload Protector，Helps prevent damage to the press and dies.

frame analysis

Highly rigid press frame, reduced frame deflection for higher precision metal stamping.

touch screen press

Color touch screen HMI, easy to view and operate.

hardened gears

UTILIZES HARDENED AND GROUND PINION AND MAIN GEARS

Provides minimal backlash resulting in improved press accuracy.

C frame-deflection

Rigid frame for AH21 model

AngularFramedeflection is 50% or less compared to competition

Welded high grade steel plate construction

Robot welded to ensure weld consistency

Plate width and thickness at the throat area help to minimize angular and rotational deflection

Compact frame design reduces floorspace requirement

Wet clutch & brake(option)

Torque transmission plates operate in a bath of oil

Oil film between clutch and brake plates results in low maintenance (change the oil every 2000 hours of operation)

Very little heat generation and component wear so performance does not deteriorate over time

Low heat generation allows high single stroke rates

Faster stopping time than pneumatic dry brake

Totally enclosed preventing airborne contamination

six point gib

6 points extra-long gibs surface on the slide, always maintained within the guides provide superior off-center guiding.

Bronze gib linear with recirculating oil lubrication system.

combined clutch

Pneumatic combined clutch/brake

oil lubrication

Recirculating oil lubrication system

Oil from all lube points is captured, filtered, and recirculated

Bearing points are monitored to ensure that they receive the correct amount of oil

Bearing temperature monitoring and broken lube line detection options available to provide additional protection
