Unique advantages of Henli standard decoiler:
1. The base uses national standard H-shaped steel (most manufacturers use I-shaped steel), which makes the whole machine have better bearing capacity and higher stability.
2. The main body of the machine adopts bending treatment (most manufacturers adopt traditional welding), and the supporting tiles and back wheels adopt thickened cold-drawn flat steel, so that the overall strength of the machine body is stronger.
3. The back arc is bent to enhance the strength of the fuselage (most manufacturers use thin sealing plates)
4. The main shaft inside the body is fixed with square nuts (most manufacturers use gasket screws) to fundamentally solve the problem of the main shaft falling off after long-term use.

Other advantages of the decoiler:
1. The fuselage box is welded by steel plate. After welding, it is annealed and polished, with strong rigidity and good appearance. The key components are all made of high-strength castings and supported by long-distance bearings to ensure the firmness and stability of the entire machine.
2. The motor is used to cooperate with the reducer to control. Using belt drive, good performance, high reliability, less failure.
3. The support tile adopts a four-blade design, and the radian of the tile matches the inner diameter of the material. The tile surface is smooth and wear-resistant, firm and durable, and will not cause any wear to the material during use.
4. Electrical components such as AC contactors, intermediate relays, and time relays all use professional brand components to ensure their long-term stable production.
5. The main shaft adopts enhanced type. Using 45# seamless pipe, after quenching and tempering treatment, it will not deform under long-term load.
6. Adopt simple electrical box control, easy to operate the machine. (Optional frequency conversion electric box, adjust the speed.)

Standard Accessories

① 8 x A-type iron

②Gantry Induction Frame

③Hand Crank Link Type Expansion

1. The A-type iron of the decoiler is a special material blocking device and limits the position of the material coil. It has two purposes: one is to make the material coil always be on the same level as the production line when uncoiling, and to avoid the deflection of the material belt during uncoiling. The second is to limit the position of the material roll to prevent the material roll from slipping and collapsing on the supporting tile. The blocking and limit device of the standard decoiler is A-type iron.

A-type iron is only suitable for coil limiters with a width that is not too wide. When the width of the material roll exceeds 800mm, there will be problems such as long installation time, tedious and complicated debugging, and poor material blocking effect. At this time, it is necessary to use the material blocking arm to limit the position.
You can learn more about this feature from this article.
Detailed introduction of the stop arm of the uncoiler.

2.About gantry induction frame,the basic principle is: when the decoiler uncoils the metal material coil and sends it to the subsequent leveler machine, due to the gravity factor of the metal material itself, material sag will occur during the transmission process. The material will form an arc between the decoiler and the leveler machine due to gravity, and it will control the material rack to stop after it touches the induction rack. After leaving, the decoiler runs automatically, so as to realize the fully automatic control of the decoiler.

However, there are unavoidable defects in this induction frame. First, the material must be a metal material. The second is that the uncoiling speed of the decoiler affects the sag height of the decoiler, which may cause loosening or uncoiling.

Therefore, you can choose to change the induction frame to multiple sets of photoelectric switch light control. To learn more, read the following articles.

3. Hand crank in the third pic is used to expand and shrink the coil by link type expansion.

Selective Accessories

decoiler

Press Arm:The main function is to press the outer ring to avoid the loose material of the coil when the uncoiler uncoils the coil. It is recommended to select this function when the thickness of the material exceeds 2.0mm or the yield strength is high.
Of course, it is only an optional function, not all materials with a thickness of more than 2mm must be selected. If the material is not heavy, you don’t need to choose this function.

Inverter: the main function is to realize the inverter speed control of the decoiler. It is used to better cooperate with the subsequent leveler machine(coil feeder machine), which can reduce the vibration of the material and make the uncoiling stability better.If you want to know more about how the inverter plays a role in the decoiler, you can read this article.Detailed introduction of the frequency converter of the uncoiler optional device.

Hydraulic expansion device: the main function is to replace the manual expansion method of the standard decoiler. The inner diameter of the decoiler is driven by oil pressure to expand, so that the inner diameter of the supporting tile is tightened, reducing the labor intensity of the expansion and contraction of the coil and ensuring complete tension. Generally, it is recommended to choose a coil of more than 3 tons. Of course, if it is to reduce labor intensity, it can also be selected for a roll of less than 3 tons.

Hydraulic feeding trolley: Its main function is to smoothly transfer the material roll to the expanding and shrinking reel of the decoiler when feeding. One is that it is more convenient and fast to change the coil material, and the other is to reduce the work intensity of manual coil loading, and at the same time effectively avoid personal safety hazards caused by carelessness in manual coil coiling, as well as damage caused by the collision between the coil material and the machine. Generally, it is recommended to choose a material roll of more than 5 tons.

There are some other optional functions, which will not be introduced one by one here. As long as you tell Henli the specifications of the material, we will choose the model for you according to the characteristics of your material, what specifications you should use, and what device you should choose. We look forward to cooperating with you.

The decoiler is the most widely used uncoiling for stamping, shearing and other processing and production to realize automatic operation. It has a variety of models, and the applicable material width can range from 0-2000mm. The model is highly customized, and the material weight, inner diameter, and outer diameter can be customized according to customer needs.Run the video as above.

Difference

Decoiler with power and non-power, how to choose the type for stamping customers?

decoiler

Powered decoiler: it has a wider application range, and most customers can choose this model.
Description of advantages: It is suitable for a wide range of materials and thicknesses (both thin and thick materials can be used). The degree of customization is high, and there are many optional devices that can be added to improve the application range of the decoiler without straining the material. Therefore, the powered decoiler is a popular model and can be used in most stamping production occasions.

Unpowered decoiler: fast uncoiling speed, which can save workshop space, but has requirements for material thickness, material, and subsequent matching equipment.
Description of advantages: fast uncoiling speed, no need to connect electricity. There is no need to reserve a long waiting area, and the floor space is saved. The non-powered decoiler is a model for a small amount of use, please contact Henli before purchasing.

Decoiler with Film Recycling:In the process of precision stamping, many electronic hardware accessories have very high requirements on the surface of the material, so a film is attached to the stamping raw material to protect the surface of the material from damage. Usually the film recycling function is installed after the leveling machine, which can ensure that the material will not be damaged during leveling, and the installation is relatively simple. But sometimes the material does not need to be leveled, at this time we can install the film recycling function on the decoiler.

Decoiler is used for recoiling:Recoiling refers to the winding and collection of continuous strip after stamping, which is usually a process of stamping automatic processing and production. Recoiling can be divided into finished product tape and waste tape. In most occasions, the more commonly used decoiler is still used for recoiling.

If the decoiler is used to collect waste, then the effect, aesthetics, and compact layering of the material coil wound on the expansion and contraction reel are not highly required. At this time, the standard decoiler can be used directly.

If the finished product is collected for packaging or subsequent use, it is necessary to add a tensioner before the decoiler, which is a mechanical device. Provides constant tension for the feed strip when the punched strip is being wound, and for the take-up of the decoiler. So as to fundamentally ensure that the material roll is collected compactly, beautiful and tough, and the quality of the finished product is guaranteed.

Decoiler is used to rewind the material as shown in the video.
