Disregarding the regulations that can be done acting directly on the mechanical parts of the machine on some plate roller ( plate bending machine ), we can distinguish the different controls as:
• Manual control
• Control by programmable positioner
• Control by CNC (Computer Numerical Control)
The manual control is performed acting on buttons, joysticks or foot pedals present on the control panel of the plate roller ( plate bending machine ).
To each single action executed (pressure of the push button etc..) corresponds a movement of the machine.
The position of the driven movable parts can be referred directly on the machine by rulers or on the control panel by digital display that are receiving the signal from encoders.
Example of control panel for manual control
The programmable positioner is an instrument that allows to store one or more positions of one or more driven movable parts of the section bending machine.
Once stored, the position can be loaded and the movable part will move from the position occupied to the stored position.
This instrument is particularly useful to perform bending works where more passages between the rolls are required, both to guarantee an higher repeatability (doing the regulations manually it is possible to commit come mistakes), and to speed up the operations.
Example of control panel for manual control with integrated programmable positioner
The commands can affect all or only some parts of the machine.
The main advantage of this type of control is that, excluding the operator participation to the working phase, a higher repeatability is guaranteed and moreover it is possible also for unskilled people to work with the plate roller ( plate bending machine ).
The usage of CNC in combination with plate rollers ( plate bending machines ) allows to obtain bending geometries like:
- Straight parts followed by curves
- Multiple radius curve
- Ellipses
