The muting mode may be selected when the bender processes complex shape workpiece.
Other protection measures should be taken to protect the operator under this mode.
2.3.4 Sensor and ST controller used together
ST type controller is a kind of bending machine safety protection device controller for
multi-process bending of complex parts Compared with SR/SP type controller, the operating
comfort of the device system is unchanged on the basis of the safety protection performance,
which reliably protects the personal safety of the bending machine operator and proves the
work efficiency of the bending machine operator. Before batch processing of parts, the user
first sets the controller to the number of machining processes of the same value in advance
according to the number of processing operations of the part (providing up to 10 independent
processes), and each process process first determines whether there is an intermediate
protective area shading according to the processing characteristics of the part, such as shading
(suppression mode), otherwise it is set to unshielded (folding box mode). Process switching
without manual intervention is required to automatically switch to the next process.
ST type process conversion timing diagram:
Due to the difference of the workpiece, the mode of bending and the shading state of the
sensor during bending are uncertain. According to the bending times of each workpiece, the
controller is divided into different processes, and the sensors are independently controlled
(normal/shielded) to ensure safe production and improve production efficiency.
The controller can be divided into N (N ≤10) processes and switched according to the variable
speed signal. In any process, after pressing the reset button, the controller returns to the first
process. After powering up, the system goes into process 1.
According to the machining characteristics of the workpiece, select the KNOB through the
process of the controller, select the specific number of the process, 1-10 processes can be
selected, when the number of the selection process is reached, the controller automatically
jumps to the first process, the specific execution cycle is displayed in the controller panel. If
three processes are selected, the controller cycle process is the first process→the second
process→the third process→the first process...
