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

Main actions:

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.

Main structure:
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

Main parameters:

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

Main actions:

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.

Main structure:
1 Upper and lower profiling die rotation
     -Drive: Servo
     -Actuating Mechanism: main shaft + bearing
2 Seaming wheel feed
     -Drive: Servo
     -Actuator: oil-free slide plate + slider

Main parameters:

1.Drum height: 200-500mm

2.Drum wrapper thickness: 0.4-0.6 (can be customized)

3.Drum Diameter: 490±0.5mm (can be customized)

4.Production cycle: 20s

ST11: Drum spider piercing

Main actions:
 

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.

Main structure:

1 Lift of drum pressing mechanism
     -Drive: servo motor
     -Mechanism: Linear module
2 Piercing
     -Drive: Hydraulic
     -Actuator: oil-free slide plate + slider

Main parameters:
 

1.Piercing diameter: 6-8mm

2.Sheet thickness: 0.4-0.6mm

3.Drum diameter: 490±0.5mm (can be customized)

4.Cycle: 15s
