Decoiler Part

A. Decoiler Part Features

1.The housing is fabricated from welded steel plates, featuring polished welding surfaces. Post-welding, the housing undergoes annealing to relieve stress, and the bearing hole is precisely machined.

2.The main motor is driven by a gear motor, incorporating a frequency converter for speed control. The sprocket propels the material in a rotating motion, and the transmission part comes with a protective cover.

3.A ø125 rotating oil cylinder is employed for expanding the inner diameter, utilizing hydraulic expansion and a wedge-shaped slider structure for the material reel.

4.The innovative four-blade design boasts a curvature that matches the material’s inner diameter. The blade surface is hard-coated, sleek, and wear-resistant, ensuring that the material remains unharmed during operation. The A-type iron features a quick-change mechanism, allowing for swift and secure blade replacement without causing any damage. The blade surface is marked with a graduated scale.

5.The Omron photoelectric switch controls the photoelectric sensor switch.

6.Outfitted with a pneumatic disc brake mechanism.

7.Integrated with pneumatic pressing and support arms, this feature assists in material loading while preventing tail-end material from dropping and causing injury to personnel.

8.The main shaft employs a ø160 45# seamless pipe, which has undergone heat treatment through quenching and tempering.

B. Straightener Feeder Part Features

1.The primary panel undergoes CNC machining center processing to ensure uniformity between the two components, while adhering to stringent quality control measures throughout the production process.

2.The leveling box structure is primarily welded using steel plates with refined welding surfaces. Post-welding and stress-relieving annealing, the bearing hole is precisely machined.

3.The roller consists of heat-treated chrome steel 40CR, subjected to high-frequency quenching and hard chrome plating. The surface hardness ranges from HRC58 to 610, with a 0.05mm thickness of chrome plating on one side.

C. System control

1.Employs Japanese Yaskawa servo motors, a Mitsubishi control system, and a touch control panel for exact control.

2.Offers high-precision feeding dimensions, guaranteeing accurate feeding to meet the growing processing requirements.

3.Provides flexible and convenient feeding length adjustments, eliminating the need for mechanical modifications; simply input the desired length size using the touch display control screen.

4.The external manual control handle enables easy mold debugging.

Optional Function

Openable Straightening Head

The entire upper straightening section is designed to be openable, allowing for easy access to clean the work rollers’ surfaces of contaminants such as oil stains, debris, and non-ferrous metal oxide layers. Typically, this feature is chosen for aluminum stamping applications.

Automatically Adjusting Correction

The correction amount can be adjusted using a geared motor or servo motor, with the system’s memory capable of storing 99 sets of numerical parameters that can be accessed at any time.

Coil Car

The material is safely and smoothly transported to the main shaft of the decoiler. This component is utilized to support the material during uncoiling, ensuring the coil enters the leveler seamlessly. Generally, it is recommended to include this feature for materials weighing more than 2 tons.

Shearing Machine

The head and tail of the material are trimmed to enable easy entry into the mold and to collect any remaining material. The system can automatically and synchronously cut coil materials, minimizing manual verification and operation time, thereby enhancing production efficiency. (It is particularly beneficial to install additional components for wide and thick materials).

Automatic Double-sided Oiler

The system enables automatic oiling of both the upper and lower surfaces of the material.

Decoiling spindle support arm

Powered by a hydraulic cylinder, the support arm sustains the end of the uncoiling spindle after loading. This action balances the main bearing’s gravity, enhances the stability of the uncoiling process, and extends the spindle’s service life.

How does Decoiler Straightener Feeder work

A Decoiler Straightener Feeder is a multi-functional machine used in the metal processing industry, streamlining the process of unwinding, straightening, and feeding metal coils. It consists of three main components: a decoiler, a straightener, and a feeder. The decoiler unwinds the coiled metal, while the straightener removes any curls or deformations using a series of rollers. Finally, the feeder moves the straightened metal into the press machine at a precise speed and length, ensuring accuracy and efficiency in production. This integrated system improves productivity, reduces material waste, and enhances overall work safety.

Comparison with Traditional Methods of Coil Feeding 

Compared to traditional methods of coil feeding, Decoiler Straightener Feeder systems offer significant advantages. In traditional methods, separate machines handle decoiling, straightening, and feeding, often requiring manual intervention, resulting in longer setup times, increased labor costs, and reduced efficiency.

In contrast, a Decoiler Straightener Feeder combines all three functions into one machine, streamlining the process and reducing the need for manual handling. This integration leads to shorter setup times, decreased labor costs, and increased productivity. Additionally, the precision and accuracy provided by the automated system minimize material waste and improve the overall quality of finished products. Furthermore, the reduced human intervention enhances workplace safety and reduces the risk of accidents.
