Structure:

·Straightener head

1. The machine head features a parallel roller design with a total of 7 straightening rollers (3 on the top and 4 on the bottom).
2. Utilizing four-point micro-adjustment, it is more suitable for processing high-precision products. Four-point independent pressure adjustment is applied to the feeding and unloading processes, effectively preventing material deviation and deformation.
3. The material support rollers are made of passive galvanized rollers, integrally formed, with a surface resistant to scratches and wear. They use mechanical bearings, providing flexible and durable rotation.
4. Cast iron handwheels are used, with a surface electroplated for traditional aesthetics.
5. Protective covers are installed on both sides of the transmission part for protection, equipped with viewing windows for convenient observation.

Straightening roller

1. The straightening rollers are made of solid bearing steel, undergo mid-frequency treatment followed by thickened electroplating, ensuring a surface hardness of not less than HRC58 to guarantee material durability.
2. GCr15 forged round steel is used, which undergoes pre-heat treatment (spheroidizing annealing), followed by turning, milling, mid-frequency treatment, rough grinding, cold stabilization, precision grinding, and finally electroplating. This process maximizes precision, concentricity, smoothness, and hardness, thereby extending the service life of the straightening rollers.

·Drive gear

The gear manufacturing process consists of the following stages: rough gear machining - tooth surface machining - heat treatment - tooth surface grinding. The rough machining involves forging to create the gear blank, followed by annealing to improve machinability for cutting. Based on the gear design drawings, rough machining is performed, followed by semi-precision machining involving turning, milling, and hobbing to achieve basic gear formation. Subsequently, heat treatment is carried out to enhance mechanical properties. Finally, precision machining is conducted according to the design requirements, refining the reference surface and gear profile. Through these processes, our gears achieve a grade of 6, exhibiting high wear resistance, high strength, and long service life.

 ·Frame part

1. This equipment adopts an integrated design of material rack and straightening unit, enhancing site utilization.
2. The material rack is designed with a cantilever beam, and all frame plates are cut with laser or plasma cutting, ensuring high precision and good equipment interchangeability.
3. All components are processed using numerical control (NC) and computer numerical control (CNC), ensuring good interchangeability.
4. The overall structure is simple, and assembly and replacement of equipment parts can be performed by general technical workers, making it convenient, fast, and greatly reducing maintenance costs.

·Electric control box

1. Utilizing silver alloy relays with all-copper coils and flame-retardant safety bases, ensuring long-lasting durability.
2. Employing safety protection adjustable circuit delay relays with silver alloy contacts, multiple adjustment dials, catering to various delay ranges.
3. Switches feature sliding contact design with self-cleaning function. Normally open and normally closed contacts utilize a separate insulated structure, allowing for bipolar operation and equipped with anti-rotation positioning and anti-loosening mounting pads.
4. Using self-resetting push buttons with light force and moderate stroke. The contacts adopt a modular combination structure with ketone-based composite points, providing strong conductivity, capable of carrying large currents, and boasting a lifespan of up to 1 million cycles.

·Power part

1. This device employs an 80-type worm gear worm vertical reducer, utilizing the gear's speed converter to reduce the rotation speed of the motor (engine) to the desired level, while achieving a higher torque output.
2. Using a vertical motor known for its low vibration and noise levels. The stationary rotor segment incorporates pure copper coils, offering a lifespan ten times longer than standard coils. Equipped with ball bearings at both ends, it ensures minimal friction and low temperatures.
