Machine Info

MT-1300 5T Hydraulic Decoiler Machine（Export to Mexico）

One of HENLI’s best-selling machine models is commonly equipped with a heavy-duty leveler and servo feeder. This particular machine is also equipped with a speed inverter, which enables smooth control of the uncoiling speed.

Features

The hydraulic decoiler (hydraulic uncoiler)is a versatile and efficient equipment for use in a variety of industries and production lines. With a maximum load capacity of 20 tons and maximum width of 1800mm, it is capable of handling large and heavy coil materials with ease. This makes it an ideal choice for industries such as metal fabrication, sheet metal processing, and rolling mill production, where it can be used in conjunction with other equipment such as leveling machines and cut-to-length lines to improve production efficiency and accuracy. Whether you’re in need of high-volume production or just looking for a reliable and cost-effective solution, the hydraulic decoiler is a great investment for your business.

A hydraulic uncoiler is a machine that unwinds metal coils and provides a consistent feed of material to a production line. Some key features of this machine include:

1.Large capacity: Certain hydraulic uncoilers are designed to handle large metal coils, up to 1300mm in width or more.

2.Hydraulic operation: Hydraulic power is utilized in the unwinding and feeding of the metal coils. This allows for precise control over the speed and tension of the material being fed into the production line.

3.Robust construction: High-strength materials like steel or cast iron are often used for key components such as the main shaft and frame to provide the machine with the durability and stability necessary to handle heavy metal coils.

4.Speed control: Variable-speed drives are sometimes included, enabling operators to adjust the speed of the material being fed into the production line.

5.Braking system: A braking system is commonly incorporated to stop the rotation of the main shaft quickly and accurately. This ensures accurate control over the unwinding of the metal coil and the feeding of material into the production line.

6.Protective casing: Some hydraulic uncoilers are equipped with protective casing around the drive components to minimize the possibility of damage to the machine during use.

7.Easy maintenance: Most hydraulic decoilers are designed for easy maintenance, making it simple to access and replace any parts that may require servicing or repair.

Standard Accessories

① Quick-change A-type Iron Device

②Gantry Induction Frame

③Motor and Reducer

1.The primary function is to replace the standard bolt-hook fastening structure with a new T-bolt quick-change structure. This takes advantage of the structural features of T-bolts, which allow for quick replacement and simplify the loading and unloading of A-type iron by turning the T-bolts 90 degrees after loosening the nuts during disassembly to remove the A-type iron.

2.Regarding the gantry induction frame, the basic principle is as follows: when the hydraulic decoiler uncoils the metal material coil and sends it to the subsequent leveler machine, material sag may occur during the transmission process due to the gravity factor of the metal material itself. This material forms an arc between the decoiler and the leveler machine, which can be controlled by the material rack to stop after it touches the induction rack. The decoiler runs automatically after it leaves, enabling fully automatic control of the decoiler.

However, this induction frame has unavoidable defects. Firstly, the material must be metal. Secondly, the uncoiling speed of the decoiler can affect the sag height of the hydraulic decoiler, which may result in loosening or uncoiling.

Therefore, it is recommended to switch to multiple sets of photoelectric switch light control for the induction frame. To learn more, please refer to the following articles.

Selective Accessories

Press arm：The primary purpose is to apply pressure on the outer ring during the uncoiling process of the hydraulic decoiler to prevent the coil’s material from becoming loose. This function is recommended when the material’s thickness exceeds 2.0mm or the yield strength is high.

Pressing Arm with Motor：If your material is exceptionally thick and flexible, we may need to add a motor to the pressing arm to enhance its efficiency. However, before adding this feature, it is advisable to consult Henli. Based on our experience, we can assess whether your material requires the addition of a motor.

Inverter: The primary purpose of this feature is to enable inverter speed control of the decoiler, which enhances its compatibility with the subsequent leveler machine(coil feeder machine). This function reduces the material’s vibration and improves the stability of the uncoiling process. If you wish to learn more about how the inverter contributes to the decoiler’s performance, please refer to this article.Detailed introduction of the frequency converter of the uncoiler optional device.

Hydraulic expansion device: The primary function of this feature is to replace the standard decoiler’s manual expansion method. The oil pressure drives the expansion of the decoiler’s inner diameter, causing the supporting tile’s inner diameter to tighten, reducing the labor intensity of the coil’s expansion and contraction and ensuring complete tension. This feature is generally recommended for coils weighing more than 3 tons. However, it can also be selected for rolls weighing less than 3 tons to reduce labor intensity.

Hydraulic feeding trolley: This hydraulic feeding trolley is capable of automatic material reception, conveyance, uncoiling of the main shaft, and resetting. It delivers high feeding accuracy, fast speed, and good stability, enabling fully automated feeding operations. The machine significantly reduces labor costs and greatly increases effective stamping working time.

To learn more about hydraulic feeding trolleys, you can read this article.The function of the feeding trolley on the uncoiler.

Spindle Head Support：If the coil weight exceeds 10 tons, a spindle head support must be added. This support can be adjusted manually or by lifting reducer. If the weight exceeds 15 tons, hydraulic adjustment is necessary.

If you are considering purchasing this device, it is advisable to consult with Henli. We can assess whether this device is required based on your materials.

Stopper Arm：The stopper arm is a device designed specifically to replace the A-type iron for the stopper limit of the hydraulic uncoiler. It is driven by a cylinder to achieve fully automatic material stop, providing a good material stop effect. The stopper arm is simple to operate and less time-consuming, making it especially suitable for stopping the position of various wide and large rolls.

To learn more about this device, you can read this article.Detailed introduction of the stop arm of the uncoiler.

Support Arm：This device enhances the stability and smoothness of the coil material uncoiling process. It also facilitates the automatic feeding action of the subsequent leveling machine (coil feeder machine). To learn more about the function of this device, please refer to this article. The support arm is an optional device that many stamping owners may not be familiar with, but it plays a significant role.

There are additional optional functions available that cannot be listed here. However, if you provide Henli with the specifications of your material, we can select the appropriate model for you based on the material’s characteristics. We can also recommend the most suitable specifications and devices for your needs. We look forward to the opportunity to work with you.

This fully automatic hydraulic decoiler, when paired with the plank leveler machine, servo feeder machine, and hydraulic shearing machine, forms a cutting line that is ideal for customers who require a cutting line but do not have a significant investment budget. The shearing and stamping production line, which included this machine, was exported to Italy and has been in service for seven years, with no signs of stopping. In general, a hydraulic decoiler is necessary for shearing lines, as the coils are usually very heavy, typically weighing more than 5 tons, and have a wide width. As a result, customers in the shearing market highly favor hydraulic decoilers.
