Digital Control with Siemens Touchscreen Display
With the Siemens touchscreen display you can set the following parameters:
- Maximum upstroke and downstroke of the hydraulic cylinder
- Pressure maintenance time on the lower platform
- Work pressure
- Decompression time
- Piece counter
- Prestop ascent/descent: function that allows you to stop the ascent or descent before reaching the quota, thus eliminating errors caused by speed and cavitation due to the weight of the mould. It guarantees an accuracy of 0.1mm.
- Alarm management
There is the possibility of storing 100 different programs with a progressive number.
You can choose between manual and automatic modes.
In automatic mode the cylinder rises automatically.
The stroke is read using a wire encoder.
The pressure is read using a transducer installed on the hydraulic control unit.
Pressure Switch
The pressure switch is a sensor that monitors the pressure of the hydraulic fluid within the system.
Its main function is the regulation of the maximum working pressure, based on the preset calibration, thus optimizing the operation of the hydraulic press based on the processes that need to be performed.
In the automatic version of the presses, it allows the automatic lifting of the hydraulic cylinder when the calibration pressure is reached.
Air/Oil Heat Exchanger
The air/oil heat exchanger is used to cool hydraulic circuit of the press and uses ambient air as a cooling source, which is conveyed onto the circuit via a fan.
It serves to prevent overheating of the hydraulic circuit and to maintain a constant oil temperature, thus avoiding damage to the hydraulic system and seals.
It is a particularly recommended accessory when the press needs to work continuously or for long production cycles.
When we install the heat exchanger we also mount the decompression valve to safeguard the cooling system.
On large tonnage presses we also mount the exchanger with recirculation and separate motor, for greater cooling effectiveness.
Photoelectric Barriers
Photoelectric barriers are safety tools that create an invisible protective barrier through the use of infrared rays.
They are configured to immediately stop the pressing process if the operator or any object comes between the photocells.
The barriers are protected by sheet metal and aluminum mesh and this configuration also allows the minimum distance from the end of the work surface to be respected.
Thanks to the photoelectric barriers, a protected work area is created and this makes it possible to operate the hydraulic press with a single button (or with a pedal), without the need for simultaneous two-hand control.
Timer
The timer is very useful for various molding operations as it allows the operator to adjust the time the hydraulic press remains closed.
It is adjustable by hand using a special wheel or it can be set digitally in the models of hydraulic presses equipped with digital control.
On request, it is also possible to keep the pressure level constant throughout the closing time.
Piece Counter
The piece counting device accurately counts and records each pressing cycle, allowing efficient production monitoring by controlling the quantity of parts produced.
The data of the pieces produced are displayed on a special digital display.
Decompression Valve
The decompression valve has the task of decompressing the pressure accumulated in the hydraulic circuit and comes into operation just before the hydraulic cylinder rises, thus avoiding overloads and preventing potential damage to the machine.
When the tamping cycle is completed or when the stop command is released, the decompression valve opens, allowing the hydraulic fluid to return to the reservoir in a controlled manner. This process ensures that the hydraulic cylinder stops safely and there are no sharp or sudden movements.
Essentially, this accessory protects the hydraulic circuit of the press and is particularly recommended when working at high pressures.
Pair of Front Supports with Adjustment
The SMB hydraulic presses can be accessorised with the pair of adjustable sheet metal supports.
These supports are adjustable both in height and laterally to meet the operator's needs.
An adjustable stop is installed on the supports which allows millimetric blocking of the sheet metal to be bent.
These supports are supplied as an option instead of the pair of supports without adjustment, which is supplied as standard equipment of the press.
Pair of Front Supports with Micrometric Adjustment
The SMB hydraulic presses can be equipped with a pair of front supports for the sheet metal with micrometric adjustment.
These supports are adjustable both in height and laterally to meet the operator's needs.
An adjustable stop is installed on the supports which allows micrometric locking in order to obtain greater precision of the fold you want to make.
These supports are supplied as an option instead of the pair of supports without adjustment, which is supplied as standard equipment of the press.
Pair of Rear Supports
The hydraulic press can be equipped with rear supports for supporting sheet metal to be bent.
These supports are equipped with a millimeter rod to measure the sheet metal and make bending operations easier.
The supports are adjustable both in height and laterally in order to satisfy the needs of the operator.
