AI Technical Summary
The existing safety light curtain for bending machines is prone to interference with the cutting tools during automatic tool changing in the tool magazine. It requires manual adjustment, which is cumbersome and inefficient. Insufficient adjustment accuracy leads to a decrease in the protective effect and poses a safety hazard.
Employing a horizontal and vertical moving mechanism, the horizontal and vertical drive motors work together to automatically adjust the position of the light curtain emitter, avoiding interference with the cutting tools. The light curtain position is also automatically adjusted according to the height and width of the mold, and precise adjustment is achieved by combining a scale and pointer.
It achieves automated adjustment of the light curtain position, improves adjustment efficiency and accuracy, avoids manual intervention, enhances tool changing efficiency and safety, and ensures the accuracy and stability of light curtain protection.
