What is an automatic hydraulic unwinding machine?
Automatic hydraulic unwinding machine is an industrial equipment mainly used for unwinding operations of metal sheets or strips. It can automatically unfold rolled materials (such as steel plates, aluminum plates, or other metal strips) into straight or flat forms for subsequent processing such as shearing, stamping, forming, etc.
The workflow of automatic hydraulic unwinding machine
The working process of automatic hydraulic unwinding machine:
- Loading rolls:
-The coil material (such as steel coil, aluminum coil, etc.) first needs to be loaded onto the unwinding machine. This is usually done by forklifts or other transportation vehicles placing the coil onto the support of the unwinding machine.
- Roll positioning:
-After the coil is placed, it needs to be positioned. For automatic hydraulic unwinding machines, there is usually an automatic positioning system to ensure that the coil is correctly installed in the center position.
- Tensioning coil:
-After the positioning of the coil is completed, the hydraulic system inside the unwinding machine will be activated, and the inner diameter of the coil will be tensioned through expansion and contraction shafts or similar devices to ensure that the coil does not loosen when unfolded.
- Expand the materials:
-Under tension, the unwinding machine begins to rotate, gradually unfolding the coil. This process is usually driven by a motor and the speed and force of rotation can be adjusted through a control system.
- Tension control:
-During the unfolding process, it is necessary to control the tension of the coil to ensure that the material does not stretch or deform due to excessive tension, nor does it wrinkle or twist due to insufficient tension. This is usually accomplished through a combination of hydraulic and electronic control systems.
- Correction function:
-If the coil deviates during the unfolding process, some advanced uncoiler machines are equipped with correction devices that can automatically adjust the position of the material to keep it on the correct track.
- Follow up processing:
-The unfolded material can be directly sent to the next processing stage, such as shearing, stamping, welding, etc. Some uncoiler machines also integrate functions such as straightening and cleaning, which can directly process flattened materials.
- Unloading:
-After the coil is used up, the remaining part will be removed and ready to be replaced with a new coil.
Application of Automatic Hydraulic Uncoiler
Application scenarios:
- Metal processing industry:
-Automatic hydraulic uncoiler is commonly used in metal sheet processing enterprises such as steel plants and aluminum processing plants, to unfold rolled steel plates, aluminum plates and other metal materials for further processing, such as cutting, stamping, bending, etc.
- Automotive manufacturing industry:
-A large amount of metal sheet is required in the process of automobile manufacturing, and the automatic hydraulic unwinding machine can quickly and accurately unfold the coil, providing necessary raw materials for vehicle body manufacturing.
- Home appliance manufacturing:
-When producing household appliances such as refrigerators, washing machines, and air conditioners, a large amount of metal sheets are required, and automatic hydraulic unwinding machines can provide the required flat materials.
- Construction industry:
-The materials used in the construction industry, such as color coated sheets and galvanized sheets, often need to be unfolded through an unwinding machine, followed by cutting, punching, and other processes to ultimately produce building components.
- Packaging industry:
-Packaging materials such as tinplate and aluminum foil also need to be unfolded before making canned goods, beverage bottle caps, and other products.
- Pipeline manufacturing:
-When manufacturing products such as steel pipes and ventilation ducts, it is necessary to unfold the metal strip before forming and welding it.
- Wire and cable industry:
-When producing wires and cables, it is necessary to unfold insulation materials or metal strips and wrap them around the cables.
- Mechanical manufacturing:
-In the manufacturing process of various mechanical equipment, it is often necessary to use metal sheets unfolded by automatic hydraulic unwinding machines as the basic material for components.
