Our customer, a global (Fortune 50) consumer products supplier, needed another “High Speed” 40 ton 4-Post press to stamp security tags. It was critical that the press be accessible on all four sides for other automation and scrap removal. A robot would feed the press from the front, roll feed would flow right to left, and scrap removal would occur on the backside of the 4-post press. Because of shipping container criteria and height restrictions at the Pacific Rim facility the power unit could not be crown mounted.
Neff supplied a H40-30M hydraulic 4-Post press with several unique criteria. The bed size was 33” L-R x 33” F-B with 30” of daylight. There was a cut-out in the bottom bolster for a vision system to be mounted. For access and height restriction reasons, Neff positioned the reservoir underneath the bottom bolster and it was shaped like a horse shoe to give access to the vision system. The power unit (motor/pump assembly) was mounted externally (upside down) to give full access to all four sides of the press. This was critical for the customer and their peripheral equipment that was integrated (feed system, robot, vision system, and scrap removal).
The press was able to complete a 12” total stroke, with 2” of work in 2.9 seconds. Our special 30 HP power unit generated ram speeds in excess of 1200 IPM. Neff included a special hydraulic pump and valve package that nullified the shock created after blanking the product. The springs in the customer’s tooling created a significant load just after blanking the product. Neff designed a special decompression hydraulic circuit and timing sequence to solve the problem. In addition, this customer required an Omron PLC (C200H Series) and several other brand specific components for part consistency for the entire work cell. Neff has serviced this customer throughout the world at their various manufacturing facilities.
