The mold plate in the workshop needs to drill holes with a depth of 500-800mm. The traditional manual drilling machine is labor-intensive, labor-intensive and time-consuming. The stroke of the traditional manual drilling machine is small, and the height of the drilling machine needs to be adjusted many times. In addition, the traditional manual drilling machine is used before the drill touches the processing surface. Fast feed is not possible, and the drilling efficiency is low; since both the template and the drilling machine are in an active state, the deeper the drill goes, the greater the swing of the drill bit, the more the hole is drilled, the more deviated, the drilling accuracy is poor, and it is difficult to discharge iron filings . How to provide special drilling equipment for the 500-800 depth of drilling of the mold plate in the workshop, and how to realize the rapid feed of the drill bit before the drill bit of the special drilling equipment touches the processing surface is a problem that needs to be solved.
