Home Appliances Industry
Steel furniture manufacturers need consistent material feeding and reliable leveling to produce components such as filing cabinets, lockers, safes, and shelving panels. During continuous stamping, thin cold-rolled and galvanized steel coils can be affected by material deformation, surface marking, and unstable feeding if the coil processing equipment is not properly matched to the material.
To address these production requirements, YouYi Precision provides a 2-in-1 uncoiler leveler feeding solution that combines coil decoiling and material leveling, together with a separate servo feeder for controlled material feeding to the stamping press.
The solution is designed for steel furniture manufacturers seeking a compact coil processing arrangement for thin steel sheet stamping.
The application involves stamping steel components used in filing cabinets, lockers, safes, bookshelves, and shelving systems.
The main production requirements include:
Stable material feeding: Maintain consistent feeding during repeated stamping cycles.
Material flatness: Level cold-rolled and galvanized steel before it enters the stamping die.
Surface protection: Reduce the risk of roller marks and handling-related damage on visible furniture panels.
Convenient coil handling: Support efficient coil loading and controlled decoiling.
Flexible production setup: Allow feeding parameters to be adjusted for different stamping operations.
These requirements make the selection of the uncoiling, leveling, and feeding equipment important to the overall stamping process.
Each production line integrates a high-speed servo feeder (NC-700A) and a precision 2-in-1 uncoiler leveler (GB-700A).
The system is designed for processing cold-rolled and galvanized steel sheets with widths ranging from 100mm to 700mm and thicknesses from 0.3mm to 1.0mm, ideal for the stamping of filing cabinets, lockers, safes, bookshelves, compact shelving systems, and other steel furniture components.
The NC-700A servo feeder has a maximum feeding speed of up to 30 m/min. Its multi-stage feeding function allows operators to preset multiple feeding parameters for stamping applications that require different feed lengths, including suitable compound-die operations.
The closed-loop servo control system uses encoder feedback to correct feeding movement, with a stated feeding accuracy of ±0.1 mm. Actual performance depends on material conditions, machine configuration, setup, and operating parameters.
The feeder also features a height-adjustable base with manual adjustment of ±50 mm, helping operators align the feeding equipment with the stamping die during setup and die changes.
The GB-700A 2-in-1 uncoiler leveler is equipped with 15 precision-ground leveling rollers, arranged as eight upper rollers and seven lower rollers, with a stated roller diameter of 38 mm.
The leveling rollers are made from high-strength bearing steel and feature electroplated and wire-finished surfaces. This roller configuration is designed to correct material flatness before stamping while helping reduce the risk of surface marking.
For steel furniture components with exposed surfaces, appropriate leveling settings and clean, well-maintained rollers are important. The final surface result also depends on the incoming material, roller condition, and machine setup.
The GB-700A configuration includes a hydraulic expansion mandrel designed to support coils weighing up to 8,000 kg.
An automatic PU pressing arm helps restrain the outer coil layer during decoiling. The hydraulic coil car, with its V-shaped cradle, supports coil loading and positioning, while a pneumatic disc brake controls decoiling tension.
These features help operators handle coils and maintain a controlled material supply to the downstream feeding equipment.
The line uses a Mitsubishi PLC and a Weinview HMI touch panel, together with Schneider Electric electrical components and AirTAC pneumatic parts.
This control configuration provides an operator interface for machine operation and supports coordinated adjustment of the equipment's operating parameters. The exact control functions available depend on the final machine configuration.
A properly configured 2-in-1 uncoiler leveler and servo feeder can help steel furniture manufacturers improve the consistency of their coil-fed stamping process.
Servo-controlled feeding helps maintain the programmed feed length during repeated stamping cycles, supporting consistent positioning of the steel strip.
The leveling section corrects incoming strip deformation before the material reaches the die. Appropriate setup can help reduce flatness-related problems in stamped panels and other furniture components.
Combining decoiling and leveling in the GB-700A reduces the need for separate uncoiling and leveling machines, creating a more compact equipment arrangement.
The hydraulic coil car and expansion mandrel support coil loading and positioning, while the pressing arm and disc brake help control the decoiling process.
The servo feeder's programmable feeding parameters and height adjustment can support production changes when the equipment is correctly configured for the relevant die and material.
Actual productivity, scrap rate, changeover time, and surface quality should be evaluated using the manufacturer's production conditions and measured results.
