AI Technical Summary
Existing technologies for drilling angle steel are inefficient, requiring repeated flipping and repositioning, which wastes time.
Design a bidirectional drilling device for angle steel, which uses two sets of drilling components to drill holes in the angle steel from both sides, combined with an elastic element for automatic clamping, reducing the need for flipping and adjustment and improving efficiency.
It effectively prevents angle steel from flipping, improves drilling efficiency, reduces adjustment time, achieves automatic clamping, and further increases processing speed.
