Operating Principles and Process Flow

1. Forming Principles

Flanging Process: The cylinder wall at one or both ends of the drum body is folded outward or inward via rolling or extrusion to form a flange with a specific angle and width. The resulting flanged edge facilitates interlocking and sealing with the drum lid, serving as a prerequisite for the airtight sealing of steel drums and metal cans.

Ribbing (Beading) Process: Annular reinforcing ribs (V-shaped or W-shaped) are rolled into the drum body at predetermined locations via radial expansion. These ribs significantly enhance the drum's hoop rigidity and axial compressive strength, preventing deformation during stacking and transportation.

2. Work Cycle Flow

(I) Pre-start Preparation

1. Check power supply, air supply, hydraulic oil level, and lubrication points.

2. Clear metal chips and debris from the worktable, molds, and rollers.

3. Verify the integrity of safety doors, emergency stop buttons, and protective guards.

4. Install the appropriate upper/lower molds and rollers based on the workpiece diameter and wall thickness.

5. Perform manual inching to ensure moving parts operate without jamming or abnormal noise.

(II) Parameter Setting

Access the parameter setting interface via the touchscreen to configure:

• Flange depth/width

• Rib position/height

• Rotation speed, feed rate, and dwell time

• Sequencing for flanging and ribbing operations

Save the program and switch to manual mode for debugging.

(III) Manual Debugging (Required for the first workpiece)

1. Start the power supply and hydraulic/pneumatic pumps; wait for pressure to stabilize.

2. Manual inching sequence: Upper mold descends → Workpiece positioning → Clamping → Flanging roller feed → Flange forming → Roller retraction.

3. Ribbing mechanism feed → Rib forming → Retraction → Unclamping → Upper mold rises.

4. Remove the first workpiece; measure flange dimensions, roundness, and uniformity; check rib depth and position; and verify the absence of cracks or wrinkles.

5. Fine-tune parameters until specifications are met.

(IV) Automatic Production

Switch to automatic mode after confirming that parameters are correct. The operator places the workpiece into the positioning fixture and presses the start button; the equipment then automatically executes the following sequence:

Automatic feeding/positioning → Clamping → Flanging → Rib forming → Unclamping → Unloading/Ejection

During mass production, it is recommended to spot-check dimensions and appearance every 10–20 pieces, promptly clear away metal chips, and inspect the tooling for wear.

(V) Shutdown and Maintenance

Press the stop button; once all mechanisms have returned to their home positions and the motors have stopped, turn off the power supply and the air/hydraulic pump. Clean the worktable and tooling, apply lubricant to rollers, guide rails, and bearings, and fill out the equipment operation log.

Key Features and Core Advantages

1. Integrated Flanging and Rib Forming

Combines flanging and rib forming processes into a single machine, completing both forming operations with one clamping setup. Compared to the traditional separate configuration of a flanging machine and a rib-forming machine, users can save approximately 30% on equipment procurement costs and reduce workshop floor space usage by about 40%, while eliminating efficiency losses and quality risks associated with transferring workpieces between machines.

2. Intelligent Tooling Switching System

The flanging machine features a multi-station upper die design, allowing for one-touch switching between different die specifications via the HMI (Human-Machine Interface), which significantly reduces downtime during changeovers. The rib-forming machine supports intelligent switching between V-ribs and W-ribs to meet diverse reinforcement design requirements, enabling rib-type adjustments without the need to change dies.

3. High-Precision Servo Control

A servo-driven lifting platform enables precise control of the rib-forming height, ensuring consistent rib positioning across all products. The rib-forming die utilizes a single-step forming process, effectively minimizing damage to the drum surface and maintaining the drum body's roundness. The dies undergo special processing to ensure exceptional service life and consistent forming quality.

4. Rapid and Efficient Production Capability

The standard model requires only 5–15 seconds to process a single unit. High-speed series machines achieve efficiencies of up to 15 drums/minute for flanging and 12 drums/minute for rib forming. A single operator can manage the fully automatic cycle simply by loading and unloading workpieces, drastically reducing labor costs. 5. Safe and Reliable Operation

• Equipped with multiple safety devices, including safety gates, emergency stop buttons, and protective guards.

• Automatic emergency stop and alarm activation in the event of anomalies (such as abnormal noise, oil leaks, or jamming).

• Fault self-diagnosis function that clearly indicates the location of issues.

• Strict operational protocols for power-off, pressure relief, and mold changing.

6. Green and Energy-Efficient Design

The E-series models utilize a full servo-motor drive system, eliminating the need for traditional hydraulic power systems and significantly reducing overall energy consumption in alignment with national carbon peak initiatives. Additionally, the design eliminates the need for periodic hydraulic oil replacement and oil waste disposal, drastically reducing maintenance requirements.
