What is it
Press-Right is a device that, combined with a properly equipped press, ensures quality control over 100% of production.
It is connected to a force and a position transducer, cylinders and signalers.
The interface to the user is a large (7.5″) touch screen display.
It can be connected to the external PLC via PROFINET, Ethernet/IP, ModbusTCP protocol.
It is prepared for connection to a computer system for management, control and execution of production processes (MES).
How it works
During a machining operation on sample parts, the instrument records data about the position of the cylinder and the force exerted by it.
You can plot the position-force graph that is characteristic of the machining performed.
– If several machining operations are performed on similar parts, their respective position-force curves will also be similar.
– If, on the contrary, one of the workpieces is different from the sample, the corresponding curve will deviate from the sample curve.
It is intuitive how controlling the curve can ensure the consistent quality of processing.
Advanced performance
The display of the curve in real time enables, in many cases, to instantly highlight an associated defect, a crucial and fundamental feature also for the usability of the instrument.
250 different jobs can be stored locally; each job can include up to eight sequential phases, with each phase capable of being repeated multiple times.
Automatic job selection is possible with automatic recognition of the equipment or with reading a barcode or data matrix.
Tool wear control, maintenance and batch size are possible thanks to a counter.
Relative positions
The position of the cylinder rod is detected by a position transducer. The dimensions referring to the zero of this transducer are called absolute dimensions, the dimensions referring to the point of contact with the workpiece are called relative dimensions.
Press-Right can also use relative dimensions making particular machining operations precise and possible, such as imprinting, bending, and machining on parts with non-constant dimensions.
Accuracy on the Stopping Point
The system detects the contact position on the workpiece and resets the reference point. If misalignment is detected, the pressing operation is interrupted to prevent damage to the equipment and materials.
Control of the point of contact
It results useful to recognize the lack or incorrect positioning of the piece being processed.
The immediate stop can safeguard the integrity of some particularly valuable pieces.
Structural Deformation Correction
The instrument continuously calculates the real position of the cylinder taking into account the deformation of the structure under load.
