1200 ton hydraulic forging coining press usa
1200 Ton Hydraulic press, BRAND NEW 100% made here in the USA . Bed size is 12"x24". The press is a real workhorse forging badges, medallions, large coins, door knobs, knives and forks. Our largest job to date has been an 7 inch round Solid brass hub cap for antique cars, this job required 6 strikings at 1200 ton!
* .In automatic mode the press will cycle 15-20 SPM (stokes per minute) at 800 tons, the smaller 250 ton press reaches speeds of 38-42 SPM @ 200 tons.
* Very reliable ...Low pressure hydraulic systems for greater safety and less leakage... One piece hardened chrome-moly steel piston... No Rubber Seals!!! ... Metallic piston sealing rings for long seal life...
* Co-axial jack cylinder for smoother, faster rapid approach... Electronic speed control... Display screen for cycle control and system diagnostics...
* Tonnage and swell time infinitely adjustable via display screen... "Honest" dwell time begins after preset pressure is reached...
* Large capacity hydraulic oil reservoir... Air to oil heat exchanger... Low speed/low pressure "JOG" mode to aid in die setting.... Fully automatic mode for use with strip or blank feeder...
* Two anti tiedown palm buttons for manual operation... Pneumatic, polycarbonate safety door with NEMA interlock switch...
* Multi hit feature allows up to six hits per cycle at different tonnage's and dwell times...
* Over travel limit switch... Press can be operated continuously at maximum rated tonnage..
* .Fred Ricci Tool Co. is a 3rd generation Tool and Die company, We can build tooling for you, all that is needed is a sample or artwork, Please call Frank @ (***)-464-9911 if you have any questions.
Heavy Hydraulic Coining Presses
Dynamic Converting Systems is committed to providing the highest quality hydraulic coin press solutions.
Our Hydraulic coining press is the result of 10+ years of continuous development. It employs state of the art hydraulic and electronic components in conjunction with a robust cylinder assembly.
Force is produced by an 18 diameter hardened alloy steel piston, energized by up to 4,800 PSI of hydraulic pressure. This force is counteracted by a 4,000 pound precision machined cast steel frame.
Dynamic Converting Systems - Hydraulic Presses
The piston moves up and down within a forged and heat treated alloy steel cylinder. Cast iron piston rings are used to permit high piston speed and to achieve long seal life. The cylinder and lower head are attached to the frame by 24 aircraft quality alloy steel tie rods with spherical washers and nuts. The tie rods are precision heat treated and receive a special post heat treat process to improve fatigue life.
In operation, the main piston is driven upwards by a small diameter co-axial piston. Oil is sucked into the main cylinder through a poppet type valve sandwiched between the lower head, and the supply flange. At the top of the stroke, the poppet valve closes and high pressure oil is introduced into the main cylinder. At the end of the pressure cycle, the oil is bled from the main cylinder through a flow control valve and sent back to the tank. The poppet valve is then opened hydraulically, and the main piston is retracted by the co axial piston, forcing the remaining oil in the main cylinder back to the tank.
All significant press functions can be set and monitored from the front panel by using the graphic operator interface.
