Flanging Equipment

This flanging step — performed on a dedicated flanging/roll-forming station — increases the drum’s radial rigidity, eliminates sharp edges, and creates a consistent mating surface for subsequent seaming, welding or assembly operations. The result is improved part strength, safer handling, and tighter assembly tolerances for downstream joining and balancing processes.

Before: the drum edge appears as a raw, straight-cut rim from the stamped sheet — sharp and mechanically weak.

After: the same rim has been transformed by the flanging machine into a continuous outward-turned (rolled) flange.

Operation Process

1. Setup & Loading: The operator selects the desired drum model on the touch screen. The upper turntable and lower forming blocks are manually replaced as needed. The operator then places the drum onto the machine and presses the dual-hand safety buttons. The forming blocks expand to secure the drum, the safety door descends, and the upper turntable lowers into position.

2. Flanging & Unloading: The turntable rotates the drum while the flanging roller assembly performs precise edge flanging. After the operation, the main spindle stops, the safety door rises, and the operator removes the finished drum. This ensures consistent flange quality, enhanced drum rigidity, and efficient semi-automatic production.

Equipment Changeover & Operation Workflow

Changeover 1

1. The operator activates the cylinder extension via the touch screen.

2. The spring compresses and the pressing plate extends. The operator places the upper turntable, rotates it to align with the slots, then engages it.

3. The operator retracts the cylinder via the touch screen, allowing the spring to reset, securing the upper turntable onto the main spindle of the bearing seat.

Changeover 2

The operator inserts the 8 forming blocks into the moving block pin holes. No screws are required, as strong magnets between the pin holes securely hold the blocks in place.

Changeover 3

1. The servo motor drives the lead screw via a synchronous pulley system, moving the wheel forward and backward.

2. The contact wheel approaches the drum, and the flanging roller retracts to perform the flanging operation.

Seaming Equipment

The Washing Machine Drum Seaming Equipment plays a pivotal role in the manufacturing process of the inner drum. This machine ensures the secure and precise joining of the drum's body and perforated drum through a mechanical seaming process.

Before: Initially, the front cover, rear cover, and drum sheet are manually assembled and positioned. This assembly forms the basic structure of the drum before the seaming process begins.

After: The assembled drum is then placed into the seaming machine, where specialized rollers apply pressure to the overlapping edges of the drum body and perforated drum. This process mechanically interlocks the layers, creating a durable and leak-proof seam.

Equipment Dimensions	3064 × 1573 × 3220 mm
Total Power	25 kW
Air Pressure	0.6 MPa
Compatible Drum Size	Diameter 480–520 mm Height 220–400 mm

Operation Process

1. Model Selection and Setup:The operator selects the required drum model on the touch screen. The upper turntable and lower forming blocks are manually replaced to match the selected model, ensuring proper alignment before operation.

2. Automatic Seaming Process:The operator places the drum into position and presses the dual-hand safety buttons to start. The forming blocks expand to secure the drum, the safety door lowers, and the upper turntable descends. Once in place, the forming disk drives the drum to rotate, and the seaming rollers complete the joint forming between the drum and covers. When seaming is finished, the spindle stops, the lifting door rises, and the operator removes the completed drum.

Equipment Changeover & Operation Workflow

Changeover 1

Changeover 1

1. The operator activates the cylinder extension via the touch screen.

2. As the spring compresses and the pressure plate extends, the operator places the upper rotary plate, rotates it to lock into the slot, and then retracts the cylinder using the touch screen. The spring resets, securing the upper rotary plate onto the bearing housing spindle.
