A decoiler cum straightener machine is a versatile industrial equipment designed to efficiently handle and process coiled metal strips or coils, commonly used in manufacturing and metalworking industries. This dual-function machine combines the capabilities of a decoiler and a straightener into a single unit, offering significant advantages in material handling, processing efficiency, and space utilization within production facilities.
**Decoiler Function:**The decoiler aspect of the machine is responsible for unwinding and feeding metal coils into subsequent manufacturing processes. It accommodates coils of varying widths and diameters, typically ranging from lightweight materials to heavier gauge steel coils. The decoiler ensures smooth and controlled feeding of the coil strip, preventing material distortion or damage during unwinding.
**Straightener Function:**The straightener component of the machine is designed to flatten and straighten the coiled metal strip. It effectively removes coil set, which is the inherent curvature present in the metal strip due to being wound in a coil. The straightening process improves the material's flatness and consistency, making it suitable for downstream operations such as stamping, punching, forming, or cutting.
**Key Components and Features:**- **Decoiling Mandrel**: Holds and unwinds the metal coil smoothly, ensuring even feeding.- **Straightening Rollers**: These are precision rollers arranged in an adjustable configuration to flatten and straighten the metal strip.- **Adjustable Entry and Exit Guides**: Ensure precise alignment of the coil strip for accurate processing.- **Feed Rate Control**: Allows operators to adjust the speed of decoiling and straightening processes as per production requirements.- **Digital Control Panel**: Provides intuitive controls for setting parameters such as feed speed, straightening roller adjustments, and monitoring machine performance.
**Benefits of Decoiler Cum Straightener Machines:**- **Improved Efficiency**: Reduces material handling time and labor costs by combining two processes into one machine.- **Enhanced Accuracy**: Ensures consistent flatness and alignment of metal strips, improving product quality.- **Space Savings**: Optimizes floor space in production facilities compared to separate decoiler and straightener units.- **Versatility**: Handles a wide range of coil sizes and materials, enhancing flexibility in manufacturing operations.
**Applications:**Decoiler cum straightener machines find applications across various industries, including automotive manufacturing, appliance production, metal furniture fabrication, and electrical equipment manufacturing. They are particularly beneficial in industries requiring high-volume production of stamped, formed, or cut metal components.
In conclusion, decoiler cum straightener machines play a crucial role in modern manufacturing processes by integrating coil handling and straightening functions. Their efficiency, versatility, and space-saving design make them indispensable for enhancing productivity and maintaining high standards of quality in metalworking operations.

.
Straightening roller
1. The straightening rollers are made of solid bearing steel, thickening plating treatment after medium frequency, surface hardness is not less than HRC58, to ensure material durability.
2. Adopt GCr15 forging round steel, after preheating treatment (spheroidal annealing), then turning, milling, intermediate frequency treatment, rough grinding and cold stabilization, then fine grinding, finally electroplating. Maximized guarantee the accuracy, concentricity, finish and hardness, and extended the using life of the rollers.
·Drive gear
Gear processing includes the following processes: gear blank processing - gear surface machining - heat treatment - gear surface fine grinding. Rough parts are mainly forging parts. Through normalizing treatment, improve the machining to facilitate cutting. According to the gear design drawings, rough machining, and then semi-finishing processing, turning, rolling, gear shaping, to make the gear basically formed. After the heat treatment to improve the mechanical properties. According to the design requirements of the drawings, finally do the finishing, finishing the benchmark, finishing the tooth profile. After all above treatments, our gear grade can reach to grade 6, with high wear resistance, high strength, long using life.
·Frame part
