WFMD20 hydraulic numerical-control plate bending machine
Properties and characters
Steel welded structure, stress elimination by vibration, high mechanical strength, and exceptional rigidity;
Hydraulic top-drive, high precision, steady and reliable;
MD20 numerical control system controls the back stop distance and up sliding stroke.

Deflection compensation unit is installed on the up die.
WFMD20 numerical control system
WFMD20-B is designed particularly for torsion type bending machine.
5.7 LCD, Chinese interface, digital input, codeless, touch-tone type page;
Control object: Servo motor, step motor;
Control shafts: 1~4 shafts, torsion bar; Ascending and descending of back shift are regulated to right or left.

Max. Command unit: 0.01mm;
Control precision: 0~0.01mm (mechanical error not contained)
Scope of position command: 0~999.9mm
Max, output frequency: 100kHz
Data storage: It can stop 50 groups. Each group may contain 20 steps; Namely, the total data storage can store 1000 data at most.
Back stop function: The parameters for whether to stop or not and stop length can be set.

Back stop and delay functions: Time for pressing slide plate down and stopping can be regulated according to the thickness of plate.
Running forbiddance function: Machine tool can not work when torsion bar drives back stop running.
Reciprocal forbiddance function: If processing quantity is pre-set, machine tool may stop when processing time is over.
Step delay function: Time of finishing present step and starting the next one.
Step selection function: 20 steps can be selected from each group of data according to the need of working step.
Single-direction function: Eliminate the clearance of silk rod.
