Introduction

·Straightener head

1. Genuine Yadeke pneumatic cylinders are utilized, featuring an alloy cylinder body with hard oxidation treatment. The solid aluminum CNC precision machining ensures leak-free riveting, smooth inner walls, no jamming, and high operational efficiency. It is durable and suitable for various working conditions.

2. The worm gear screw lift mechanism is employed, with the casing made of HT200 material and bearings from top-tier brands. It is buried to enhance impact resistance, resulting in a sturdier and more durable structure.

3. Cast iron handwheels with surface electroplating treatment are used, representing a classic design.

·Frame part

1. This equipment adopts an integrated design of decoiler and straightener, enhancing site utilization.
2. The decoiler features a cantilever beam design, with all frame panels cut using laser plasma cutting, ensuring high precision and good equipment interchangeability.
3. All components are CNC machined, ensuring good interchangeability.
4. The overall structure is simple, allowing assembly and replacement of equipment parts by general technical workers, making it convenient, fast, and greatly reducing maintenance costs.

·Straightening roller

1. The correction wheel is made of solid bearing steel, undergoes thick electroplating treatment after medium-frequency heating, ensuring a surface hardness of no less than HRC58 to guarantee durability of the material.
2. Made of GCr15 forged round steel, it undergoes preheating treatment (spheroidizing annealing), followed by turning, milling, medium-frequency treatment, rough grinding, cold stabilization, precision grinding, and finally electroplating. This maximizes precision, concentricity, surface finish, and hardness, extending the service life of the correction rollers.

  ·Drive gear

The gear manufacturing process includes the following steps: rough gear shaping, gear surface machining, heat treatment, and gear surface finishing. Rough gear shaping mainly involves forging, followed by normalization treatment to improve its machinability for cutting. According to the gear design drawings, rough machining is carried out, followed by semi-precision machining involving turning, rolling, and gear cutting to achieve basic gear formation. Subsequently, heat treatment is performed to enhance mechanical properties. Finally, precision machining is carried out according to the design requirements to refine the gear dimensions and tooth profile. Through these processes, our gears can achieve a grade 6 level, characterized by high wear resistance, high strength, and long service life.

·Power part

1. Utilizing an 80-type worm gear vertical speed reducer, this device employs the gear's speed converter to reduce the motor's rotational speed to the desired level, while generating increased torque.

2. Equipped with a vertical motor, this system features low vibration and noise levels. The stationary rotor section utilizes pure copper coils, providing a lifespan ten times longer than standard coils. Additionally, both ends are fitted with ball bearings, resulting in minimal friction and low temperatures.

·Electric control box

1. Utilizing silver alloy relays with full copper coils and flame-retardant safety bases, ensuring long-lasting durability.
2. Incorporating safety-protected adjustable circuit delay relays with silver alloy contacts and multiple degree discs, catering to various delay ranges.
3. Switches featuring sliding contacts with self-cleaning functionality, with normally open and normally closed contacts utilizing a separate insulation structure, capable of working in opposite polarities, and equipped with anti-rotation positioning and anti-loosening mounting pads.
4. Featuring self-resetting push-button switches with light actuation force and moderate key travel. The modular contact points employ ketone-based composite materials, providing strong conductivity and capable of carrying large currents, with a lifespan of up to 1 million cycles.
