The flanging machine is a core piece of equipment in the middle section of a steel drum production line, located after the rolling and welding processes. It is responsible for flanging or rolling the edges of both ends of the drum body, preparing it for subsequent sealing with the bottom and top. Through a hydraulic or servo drive system, the equipment folds the drum ends into a flanged structure with a specific angle and curvature, ensuring a tight seal at the bottom and top, meeting sealing requirements. Modern flanging machines can be integrated with corrugating machines, simultaneously completing both flanging and corrugating processes, and are suitable for drum diameters ranging from 60 to 210 liters. The equipment can be configured vertically or horizontally, driven mechanically or hydraulically, with a capacity ranging from 180 to 360 drums per hour. High-precision flanging ensures the sealing and stacking strength of the steel drums, making it one of the key processes on the drum production line that directly affects the quality of the finished product.
