Features
1. Crafted with precision, the straightening wheel is constructed of solid bearing steel. Post high-frequency heat treatment, it's meticulously milled and hard chrome plated. This process ensures an ultra-smooth, flat surface, minimizing any risk of scratching during the straightening process.
2. Seamlessly versatile, this machine can function independently or be synchronized with MT or DBMT auto uncoilers, optimizing the straightening performance for superior results.
3. With a robust large cylinder for material pressing, adjustments are made using a precision-engineered synchronous worm gear and worm screw system. Each turn of the handle delivers a 1mm adjustment to the upper wheel, allowing for fine-tuning and unrivaled accuracy.

The head of straightener
1. Ingeniously designed, the head features a parallel roller setup with 9 finely-crafted rollers (4 upper, 5 lower), ensuring consistent quality and precision.
2. The incorporation of a large cylinder for pressing material makes it adept for high-precision applications. Its synchronized worm gear and worm screw system effectively prevent material deviation and deformation.
3. The support roller, made from galvanized material, is crafted without power, ensuring surface resistance to scraping and grinding. Equipped with durable mechanical bearings, it offers smooth and flexible rotation.
4. Featuring a classic cast iron hand wheel, its surface is plated for longevity, embodying the most traditional and reliable design.
Straightener roller
1. Engineered from solid bearing steel, the straightener wheel is thickened and electroplated post intermediate frequency treatment, boasting a surface hardness of at least HRC58 to ensure enduring performance.
2. Utilizing GCr15 forging round steel, subjected to a meticulous preheating and treatment process, including spheroidizing annealing and multiple grinding stages, the roller achieves unparalleled precision, concentricity, and hardness, significantly extending its service life.
Drive gear
The gear undergoes a comprehensive processing journey starting from gear blank processing to tooth surface finishing. Heat treatments and precise machining ensure each gear reaches a grade 6 standard, offering high wear resistance, strength, and an extended operational life.
Power section
1. Featuring a model 80 worm gear vertical reducer, it utilizes a gear speed converter to adjust motor speed, achieving the desired revolutions and enhanced torque.
2. The use of a vertical motor reduces vibration and noise. With a rotor composed of a pure copper coil, it enhances longevity, offering a lifespan ten times that of an ordinary coil. Equipped with low-friction, low-temperature ball bearings at both ends.
Electric control box
1. Built with a silver alloy relay and a full copper coil, it provides a flame-retardant, safety-first design, ensuring endurance and reliability.
2. The safety protection adjustment circuit integrates a time delay relay with a silver alloy contact, offering diverse and dial options to accommodate various delay ranges.
3. Equipped with a sliding contact switch featuring a self-cleaning function, it accommodates multiple poles with its separate bonding structure and anti-rotation features, preventing loosening.
4. Featuring a self-duplex flat button, it has a light touch, moderate key range, and a modular building block design. The contact, made from keto-base composite points, showcases exceptional conductivity and a high current capacity, offering a lifespan of up to one million uses.
Feeder cylinder
1. Utilizing authentic Air TAC cylinders, the alloy body is hard oxidized, ensuring robustness and a leak-free riveting system.
2. Experience solid aluminum CNC precision machining that boasts wall grinding with unparalleled smoothness. This ensures non-blocking performance and exceptionally high efficiency, enhancing your productivity like never before.
3. Engineered for high-strength operations, this machine is remarkably durable and ideally suited for a wide array of challenging working conditions, delivering reliability and performance you can trust.
