Machine Details

-ST 2
V-bending & lock-seaming
Main actions:
1. The sheet is pushed into the machine by the servo pushing mechanism for positioning.
2. Bending knives on both sides begin to punch for V-bending.
3. The arms act for sheet rolling, and the inner support holds the drum wrapper tightly.
4. Start lock-seaming and take out the drum wrapper after completion
Main structure:
1 Material positioning and clamping
-Drive: Servo motor
-Positioning datum: positioning block
2
V-shaped bending
-Drive: hydraulic
-Bending knife lifting: hydraulic + rail slider + guide column and bush
3 Rolling and lock-seaming
- Rolling drive: cylinder
- Tightening drive: servo + roller screw
- Seaming drive: hydraulic + guide column and bush
Main parameters:
1. Blank thickness: 0.4-0.6mm (different thickness needs to switch the riveting die)
2. Material width: 300-500mm
3. Maximum tensile strength: 5500N/50mm (standard test method)
4. Production beat: 25s

ST4: Flanging
1. After the drum is placed on the support mold of the flanging machine, the support mold supports the drum tightly.
2. The supporting cylinder descends and the supporting mold rotates.
3. The flanging wheel group feeds for flanging, and returns after the flanging is completed.
1 Support mold
-Tightening drive: cylinder
-Tightening mechanism: connecting rod mechanism
2 Drum holder transverse
-Rotation drive: geared motor
-Actuator: sprocket and chain mechanism
3 Drum holder clamping
-Clamp drive: cylinder
1.Material thickness: 0.5mm, 0.6mm
2.Material width: 300-500mm
3.Drum Diameter: 490±0.5mm (can be customized)
4.Production cycle: 20s

ST9: Front cover, back cover, drum wrapper Seaming
1.The pre-assembled drum enters the profiling die of the spin seaming machine
2.The upper profiling die is lowered into the front cover.
3.Synchronous rotation up and down drives the drum to rotate, and the seaming wheel feeds for seaming operation.
4.After the spin seaming is completed, the upper profiling die returns back.
1 Upper and lower profiling die rotation
-Drive: Servo
-Actuating Mechanism: main shaft + bearing
2 Seaming wheel feed
-Actuator: oil-free slide plate + slider
1.Drum height: 200-500mm
2.Drum wrapper thickness: 0.4-0.6 (can be customized)

ST11: Drum spider piercing
1.Put the drum wrapper into the profiling blocks for positioning.
2.The drum pressing mechanism moves down to the designated height.
3.The pericing mechanism starts work, after that, the drum pressing mechanism goes back.
1 Lift of drum pressing mechanism
-Drive: servo motor
-Mechanism: Linear module
2 Piercing
-Drive: Hydraulic
1.Piercing diameter: 6-8mm
2.Sheet thickness: 0.4-0.6mm
3.Drum diameter: 490±0.5mm (can be customized)
4.Cycle: 15s
