The model 6987 RAM press is a hydraulic down acting single cylinder type press, offering maximum control throughout each operating cycle. The press is automatic through each cycle; the operator simply charges the die, pushes two mushroom buttons (two as a safety feature) to activate the press and prepares to receive the formed article as it is released from the final die member when the press opens. The press may be operated by one operator or with an assistant depending upon production planning.
The capacity of this press is rated at 120 tons based on a system pressure of 3100 PSI.
Fast approach 320 in/min
Pressing- The downward moving top platen will upon selection go into an automatic slower pressing speed up to six inches before closing. This speed is adjustable from 0 to approximately 44 in/min.
Slow parting- The speed of the top platen upon opening of the die may be adjusted independently of the slow pressing speed.
Fast parting 425 in/min.
The press and pumping unit are constructed as separate units. The standard arrangement is to locate the pumping unit approximately 6 feet behind the press. The pumping unit may be located as far as 50 feet away in any direction. Special piping and sizing can be furnished upon request.
Two bolster plates 30" x 39", approximately 1-1/4" thick, nickel plated, and bolted to the platens are furnished. These are provided with "T" slots for mounting standard die cases onto the press. Bolster plates have the advantage of being easily drilled and tapped for new mounting holes, worn mounting holes may be easily repaired, and the ground surfaces may be readily resurfaced.
