Structure 

· Material part 

The frame component of the material frame is constructed from Q235B, chosen for its notable elongation, robust strength, and resilience, making it ideal for punching and welding in the fabrication of general mechanical parts. Q235B material undergoes laser cutting to ensure overall plate flatness. Following straight cutting, CNC machining is employed to ensure precise hole positioning. Subsequently, CO2 protection welding is utilized to secure the rack's dimensions after hole processing. Finally, annealing heat treatment is applied to modify the internal steel structure, enhancing steel performance. This heat treatment process not only fortifies the metal material to maximize its potential performance but also reduces structural weight, improves mechanical product quality, and significantly prolongs machine part service life. Additionally, it eradicates welding process defects, diminishes segregation, alleviates internal stress, and promotes uniformity in steel structure and properties.

· Material spindle

The spindle bearing bore is meticulously crafted using a horizontal boring machine, ensuring a coaxiality precision of less than 0.015mm. For the main shaft of the material frame, 40Mn tube forging is employed. Through processes of spheroidizing annealing, quenching, and tempering, the main shaft's flexibility is significantly enhanced, surpassing that of typical carbon steel pipes commonly utilized in the industry. This enhancement optimizes the load-carrying capacity of the spindle, facilitating smoother coil starts and stops while reducing motor load.

· Left and right vertical board

The left and right vertical plates of the straightening head are crafted from cast steel ZG25, renowned for its exceptional strength, plasticity, toughness, and welding capabilities, ensuring minimal deformation and high stability. Each set of equipment's left and right vertical plates undergo precision molding, followed by casting with ZG25. Subsequently, annealing is applied, subjecting the material to prolonged high temperatures and gradual cooling. This process serves to rectify or eliminate structural defects and residual stresses inherent in steel due to casting, forging, rolling, and welding processes. Its primary objectives include preventing workpiece deformation and cracking, facilitating workpiece softening for machining, refining grains, and enhancing structure to improve mechanical properties. Through CNC machining, the accuracy of the vertical plate holes and overall stability is meticulously maintained.

· Correct roller part

The correction roller stands as the pivotal component within the Uncoiler, Straightener, Feeder, 3 in 1 setup. In Lihao Machinery's processing approach, GCr15 round steel serves as the foundation material, initially forged into shape. The roller undergoes a series of meticulous treatments, commencing with pre-heat treatment via spheroidizing annealing, followed by stabilization through carburization, milling, intermediate frequency treatment, coarse grinding, and deep cooling. Subsequent refinement processes ensue, culminating in plating. This comprehensive treatment regimen ensures optimized accuracy, concentricity, finish, and hardness, effectively prolonging the correction roller's operational lifespan.

· Gear section

Lihao Machinery employs a meticulous gear machining process, which involves several key steps:

1. Gear Grinding Processing: Initial shaping of the gear profile.
2. Tooth Surface Processing: Refinement of tooth surface geometry.
3. Heat Treatment: Enhancement of mechanical properties through heat treatment.
4. Tooth Surface Finish Grinding: Finalization of tooth surface smoothness.

For gear components, forging is the primary method, followed by normalizing treatment to improve machinability. Gears are then crafted according to precise drawings, progressing through roughing, semi-finishing, rolling, and gear shaping stages to achieve near-final form. Subsequent heat treatment optimizes mechanical properties. Finally, according to design specifications, the gears undergo final finishing and tooth profiling. This comprehensive approach yields gear ratings of up to grade 6, ensuring exceptional wear resistance, high strength, and extended service life.
