The hydraulic workshop press, model PFF, is ideal for various processes, including straightening sheet metal, for assembling and disassembling bearings, bolts, washers or for carrying out stamping and material deformation work and is perfectly suited for intensive use in maintenance and repair workshops or even within industrial plants. The press is equipped with a two-speed control unit which is activated by simultaneously using the lever and the button. The control unit also features a knob (1) for adjusting the maximum working pressure and a pressure gauge (2) to display the value of the pressure in use. There is also an indicator (3) for the oil level inside the hydraulic system.
The PFF hydraulic workshop press is available with a hydraulic cylinder with a stroke of 500 mm. The cylinder can be fixed or mobile. In the version with a mobile cylinder, the press is equipped in models up to 100 tons with a handwheel for the transverse movement of the cylinder from left to right, while for models starting from 150 tons, the movement of the cylinder occurs via a hydraulic motor, due to the fact that the cylinder would be too heavy to move manually. The cylinder can be stopped at any point and this function is very useful because it allows you to move it laterally and then lower it to the exact point of the sheet metal on which you want to work, without having to move the metal piece.
The large front opening allows for easy positioning of long or wide workpieces. The work platform of the PFF hydraulic press is hollow, which allows for processing of the material at height. The work support plate, as well as the pair of V-prisms, are available as optional equipment.
The work platform is raised by a hydraulic motor and with the use of a lever. You can choose up to 3 different working positions. The work platform is locked using thick steel pins, which eliminate any unwanted movements. To prevent them from slipping out, they are anchored using special cotter pins.
The press structure is made of very thick milled steel, which is completely welded along the entire perimeter of the press with oversized welds. In fact, to ensure that the press can absorb even the highest pressures and maintain its structure unchanged over the years, it is necessary that the welds are made in an optimal manner. This differentiates us from most of our competitors who, to contain production costs, make much thinner welds and only in some points of the frame. Below on the left is an example of welding made by SICMI and on the right that of a European manufacturer.
Accessories:
The semi-automatic mode involves the installation of microswitches that allow the cylinder stroke to be adjusted and thus its maximum descent and ascent point to be set. Microswitches are sensing devices that monitor and signal the extreme position of the cylinder during its movement. When the cylinder approaches its final position, the microswitches detect the stopping point and send a signal to the press control system.
The metal work support plate is used to conveniently position the piece to be machined. It is positioned on the hydraulic press bed and is equipped with mechanical fixing blocks. It is available in various sizes depending on the tonnage and size of the workshop press on which it is to be installed. This support plate is characterized by its high thickness, which guarantees excellent resistance to the strong pressure exerted by the cylinder during the pressing phases and therefore prevents the plate itself from deforming.
The pair of V-prisms has the function of supporting the metal piece to be machined and is fixed to the work surface of the hydraulic press. They are usually used for straightening and bending of tubes, rods or metal profiles inside mechanical workshops. The V-prisms are made of painted raw iron and are milled at the support point.
As an additional safety system, metal blocks are provided on all workshop presses that have a movable floor. These metal blocks are positioned at the lower end of the press and are completely welded to the machine structure. Their function is to protect the operator's feet from the accidental fall of the work table. These mechanical blocks prevent the work table from touching the lower part of the and thus leave a safety space for the user's feet, preventing them from being crushed.
All presses produced by SICMI include safety systems for anchoring hydraulic hoses. In fact, the force released by a pressurized hose, in the event of the fitting slipping off, would be very dangerous for things or people in the vicinity. This is why the hydraulic hoses of all presses produced by SICMI are fixed using the Stopflex retention system, which was designed to stop the stroke of the slipped hose and prevent the force released inside it from triggering a fearsome
As an additional measure to ensure the safety of the operator and to safeguard the machine, a maximum pressure valve is installed inside the hydraulic power unit on all hydraulic presses produced by SICMI. The maximum pressure valve has the function of regulating the maximum pressure in the hydraulic circuit. It is used to protect the pump and other components of the system from excessive pressure and therefore to maintain a constant level inside the hydraulic circuit.
