The hydraulic steel drum expanding cone machine is a specialized forming unit used in steel drum production lines for precision expansion and shaping of drum bodies. It applies controlled hydraulic pressure to adjust and form the drum structure, helping achieve accurate dimensions and improved body rigidity. Designed for 200L steel drums, chemical barrels, oil drums, and industrial metal containers, the machine features a robust hydraulic system, dedicated forming tooling, and stable control technology. It provides consistent shaping results while reducing manual operations and improving production efficiency. The expanding cone machine can be integrated with drum rolling machines, seam welding equipment, flanging machines, rib forming systems, and sealing units to create a continuous automated steel drum manufacturing line. Its reliable construction, accurate forming performance, and convenient operation make it suitable for modern drum production applications.
