Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, specifically to a hollow steel pipe drilling device. Background Technology

[0002] Hollow steel pipes are punched to install other accessories. Existing equipment uses hydraulic re-punching to punch holes, which moves the hollow steel pipe within the punching seat to change the punching position via a traveling mechanism. The number of holes processed at one time depends on the number of punching positions inside the punching seat. After punching, new hollow steel pipes need to be fixed, resulting in low overall efficiency. Therefore, we propose a hollow steel pipe punching device. Utility Model Content
