170 TON Trim Press for Appliance Industry
A major appliance manufacturer contacted Neff to build a press for trimming out inner door appliance panels. They needed a large bed area with ram control system.
Neff Press Inc® designed and manufactured (1) 150ton four post press with the following specifications: Overall system footprint 120″ x 72” x 140″ Tall. 96″ x 60″ between the posts, with 29″ daylight, and 13″ stroke. The press was capable of cycling every 3.5 seconds and used a floor-mounted 50hp power unit. The design called for split removable bushings on the pins as well an 8 point lube system, and die safety block integrated into the control system.
The press controls system consisted of an Allen Bradley Control Logix with a 10 slot rack, Ethernet module, (2) 16 point discrete input modules, (2) 16 point relay output modules, and (1) 8 point analog input module. We used linear transducers and pressure transducers for feedback, diagnostics, and calibration. This system also included an energy saver program as well as a multiple counters. Neff provided light curtains with fixed mesh on the sides. We also supplied English and Spanish language MMI screens.
Neff was responsible and provide the transportation, rigging, installation, and training on-site in Mexico.
