3、Calibration by Manual Moving Mode
Operators can move Y axis (slider), X axis (back shield) and R axis (finger shield) for
position calibration in manual mode.
1）On the programming page, click on the menu icon and select "Manual Move" from
the pop-up menu to enter the manual page.
2）Click - /++ or button to move the selected Y axis (slider)/ X axis (back shield).
When each axis is moved, the current value of the axis coordinates changes
accordingly, and the movement can stop until it moves to the appropriate position.
3）Setting the reference point for the X-axis
Use the measuring tool to measure the length of a reference position (from clamping
point to back shield), and then write the measured value in the settings above the back
shield icon .
A method of measuring the length of the backstop from the clamping point to the
backstop: after X-axis moves any distance, take a piece of sheet material and place it
between the upper and lower dies, push the sheet material to hold back the backstop at
one side; then step down, make the upper die move downward to just press the sheet (a
little strength but the sheet material is not deformed). Finally, step on the foot to make
the upper die return to the upper dead point, and measure the impression marks and the
small plate. The vertical distance on the side of the back shield is the length from the
clamping point to the back shield.
4）Setting the reference point of Y axis
Use the measuring tool to measure the length of a reference position (from the bottom of
the lower die to the top of the upper die), and then write the measured value in the
settings above the back block icon .
A method of measuring the distance from the bottom of the lower die to the top of the
upper die: step on the foot to make the upper die return to the upper dead point, move
the Y axis for a certain distance at will, step on the foot, make the upper die move
downward to the slider position (that is, the position can no longer be downward), step
on the foot and do not put down, and finally measure the vertical distance from the
bottom of the lower die to the top of the upper die.
