HE provides a flexible choice for sheet metal stamping line. In some of the small tonnage stamping that using thin material, an uncoiler, and a servo feeder machine can become a reliable and straightforward coil feeding line for the application. A precision straightener machine can also be integrated into this line if needed.
Yield Strength: ≤245 N/mm2
Tensile Strength: ≤392 N/mm2
Material Thickness: under 2.0 mm
Uncoiler Machine (passive, motorized, double head for optional)
Coil Feeder (mechanical roll, servo roll feeder for optional)
0-20m per minute
The uncoiler and coil feeder have the independent control systems and sensor rack for loop control, which is easy for installation and operation.
HE can provide variety configuration choice depends on your material specification. For uncoilers, there's two expansion type for different coil weight range, manual expansion, and hydraulic expansion.
As for some flexible metal coil materials, it will equip a hold-down arm. The pressing arm is pneumatic type device with non-motorized PU rubber wheel, to add pressure on the coil outside to avoid loop rebounding in uncoiling process.
A contact sensor rack will detect and controls the material loop, and induction rod is also available if neede. And some of the uncoilers will equip coil car for smooth coil loading.
If needed, HE provides high precision straightener as well as the conventional type, to meet the straightening requirements from different product stamping line.
The most popular coil feeder is HE servo feeder RNC series. Servo feeder with mechanical release NCF is also available for higher speed request.
Medium duty uncoiler MT-F as an example reference:
Uncoiler operation: Motorized
Uncoiler expansion: Hydraulic expansion
Coil hold-down arm: Pneumatic type, non-motorized PU wheel
Loop control: Sensor rack
Operation control: Control handle with manual button
Loading capacity: 5000kgs
Brake system: Band brake
HE servo feeder is a reliable choice for sheet metal feeding process, meet various type coil feeding requirements.
The detail consideration of mechanical design guarantees high synchronistic mechanical structure, which is a fundamental guarantee for high-precision feeding.
Feed rolls are by sided gear driven, which has an ISO 6 accuracy level. And the feed rolls are made by high quality bearing steel; hardness reaches HRC60.
As for the electric system, the leading international brands' components make sure reliable control and easy maintenance.
Computer control system guarantees fast and accurate performance, and HE provides multiple control systems for optional in for user habits in different countries.
