Most metal raw materials used in sheet metal stamping companies are the coil type. A metal coil must be uncoiling and levelled to eliminate internal stress, then fed into the stamping press machine.
The loop type coil feeding lines usually require two or more independent equipment to be used together, comparing with loop type coil feeding line, the combined decoiler straightener feeder coil feeding line has many advantages:
1. Modular control, simple coil handling operation
A compact coil feeding line is not only a simple combination of uncoiler, straightener, and feeder but also highly integrated control in operations. The hydraulic station, coil car, uncoiling motor, spindle and inverter, straightener part, servo feeder motor are connected with the PLC modular system and controlled by one touch screen, which is quite convenient for operators.
2. High precision straightening and feeding performance
For a loop type coil feeding line, there will be a material loop between each two equipment, means all of them need an inverter for speed control, even so, the running match will not be fully synchronized, which will affect the precision of feeding. A decoiler straightener feeder coil feeding line can synchronize these three parts, has control of PLC closed-loop system, which ensure a high servo feed accuracy.
3. Wide range of metal coil processing applications
The application range of decoiler straightener feeder coil feeding line is much wide than other types. It can handle high strength steel and also normal steel in high thickness. It can handle steel thickness up to 12.0mm coil width up to 1800mm with high precision straightening performance. A compact decoiler straightener feeder coil feeding line is necessary for the high strength steel stamping in automotive, construction, aerospace or electrical appliance manufacturing.
4. Save workspace, easy installation and maintenance
The compact coil feeding line is easy to install, which can enter into mass production in a short time. Without a long material loop, the coil feeding line length is usually no more than 5m, some models such as GLK2 is only 2.5m length, which will save workplaces of stamping room. With international brand core components, automatic lubrication system and self-inspection procedures, the compact coil feeding line have a very low failure rate and easy to maintenance.
Compact coil feeding line (Servo straightener feeder with uncoiler) is HongEr’s major product: GLK2 series for thin material handling, GLK3 for medium thickness steel coil processing, GLK4 for the thick coil thickness up to 6.0mm, GLK5 series for heavy-duty steel thickness up to 9.0mm, and also GLK-H series for high strength steel stamping. HongEr also provides customized coil handling solutions according to specific sheet metal coil processing.
