Photo "above" is our 800 metric ton / 880 US ton crown during final machining on the boring and milling machine. You are looking at the top view where you can see the large open cavity will accept the "Apex Center Drive Gear Box". By placing the drive in the center this pushes the crankshaft journals further out to the left and right which is better to withstand off-center load conditions.
Back in the 1980's Sutherland sold the first Center Drive PMX-300 from Aida Presses in Japan to a California customer. This led us to develop and install many center drive press series over the last 30+ years. The 440 ton center drive "below" has been running multi-shift for the last 17 years. The new "Apex Center Drive" has the new larger drive box opening as shown above for ease of manufacturing, installation, ease of press timing and service.
The slide body "below" demonstrates the wide spacing of the yellow connecting rods that connect to the crankshafts in the APEX Crown.
This design is well suited for large die areas left to right and when off-center load are expected. The slide is fabricated with special attention to stiffness toward the center of slide, between connecting rods.
The slide is guided with eight (8) point "taper wedge" full length slide guides with high compression bronze replaceable wear strips. We run very close tolerance to assure precision accuracy every stroke of upper to lower die contact.
Photo (left) is a 440 ton, 120" x 60" during rigging installation. Our frames are designed for ease of installation and alignment of bed to uprights and uprights to crown. We use taper round dowel pins (photo below) on each mating surface to remove the guess work for the rigging companies. This photo also demonstrates the ultra wide suspension points in the slide body as shown where the yellow connecting rods will come up to crown and connect with the mating crankshaft journals.
The 660 ton, 144" x 60" below is equipped with two (2) front to back rolling bolsters. This press was originally installed for a Tier One automotive stamper in the Southern states.
As you can see in photo (left) the crown of the 660 ton has been prepared and is being lowered onto the uprights. In this particular install the end user had plenty of ceiling height to go up and over tie rods.
With core drilled tie rod holes, we can stack the press within a few inches of its own height. This allows the tie rods to be lowered into a round hole and then pulled back up after the crown has been installed.
We provide all cad drawings for press and foundations to match the need for our customers building requirements and floor to bolster heights. At the same time, for customers with long feed lengths, a coil loop pit foundation can be added.
The I-PRESS AB PLUS press and automation control come standard on the KS2-APEX Series.
This is the most fully featured control on the market. Built on an AB Platform for hardware with the latest Guard-Logix expandable safety PLC assures reliability and safety.
Our I-PRESS "Easy Nav" interface is housed in the new Panel View 10" Performance Plus touch screen. What other controls providers call options we can standard feature sets. Included are, 12 programmable cams, 16 die protection circuits, 4 point tonnage monitor, 200 job memory, fault log and fault diagnostic to name a few. Special mode is also included which offers, Micro Inch for set up between 160 & 220 degrees, SSD~Single Stroke on Demand and CSD Continuous on Demand for Gag Feed and cut off operations.
