TOOL CONTROL

 

As shown in Figure 8.2.3, the tool control interface is utilized to set primary travel velocity and binder force. The binder force control is activated by selecting the BINDER FORCE check box.

 

 

Figure 8.2.3 The Tool Control Interface.

 

 

Depending on the draw type, the tool velocity and force are applied according to the following control scheme:

 

CRASH FORM                                               Upper tool with defined tool velocity                          

           

INVERTED DRAW (SINGLE ACTION)       Upper tool is controlled by velocity

                                                                             Binder is controlled by either velocity or force

               

TOGGLE DRAW (DOUBLE ACTION)         Upper tool is controlled by velocity

                                                                              Binder is controlled by velocity or force

 

FOUR PIECE DRAW                                        Upper tool is controlled by velocity

                                                                               Upper binder is controlled by velocity or force

                                                                               Lower binder is controlled by velocity or force

 

If the default unit is selected, the unit of velocity and force are in mm and Newton, respectively.

 

 

Note:

 

1.   In the QS interface, all force controls are implemented after the binder is closed using velocity control. That is, the velocity control is switched to force after binder closing.

 

2.   In the QS interface, the force applied to the lower binder (in FOUR-PIECE DRAW) is controlled by velocity or force with rigid body control.  Rigid body control will prevent the lower binder from moving up before the upper and lower binders clamp the blank.

 

 

 

For example (INVERTED DRAW):

 

If the user needs to control the punch with velocity and the binder with force control:

a.        Provide punch travel velocity (default is 5000mm).

b.       Provide binder velocity (default is 2000 mm).

c.        Provide binder force (default is 200,000 Newton).
