Groove steel edge tooth forming equipment

The invention discloses channel steel edge tooth forming equipment which comprises a rack, a leveling device used for leveling a steel plate, a rolling and ribbing device and a hobbing device used for hobbing the edge of the steel plate are sequentially arranged on the rack from right to left, and a driving device used for providing power for the leveling device and the rolling and ribbing device is further arranged on the rack. In the plate machining process, after a plate is machined in the previous working procedure, leveling, calendaring and ribbing and hobbing machining are directly conducted, meanwhile, the tooth depth can be automatically adjusted according to different requirements, waste of raw materials is avoided by applying a special hobbing machining method, the matching degree of the front working procedure and the rear working procedure of the device is high, automatic production is achieved, manual labor is reduced, and the production efficiency is improved. The device is suitable for large-sc
