Brief Profile of Hydraulic Decoiler Straightener

The Hydraulic Decoiler Straightener is a machine designed to uncoil and straighten metal sheet coils quickly and efficiently. As a two-in-one unit, it saves installation space and reduces the need for precise material transition segments during the straightening process to maximize machine performance.

With a width range of 100-800mm and thickness range of 0.5-4.5mm, it can handle metal sheet coils with a weight capacity of between 1000kgs to 3000kgs. This machine is ideal for use in the hardware stamping, electrical products, and computer shell production industries.

Our Decoiler Straightener utilizes pneumatic pressure on upper and lower straightener rollers, combined with worm gear adjusting, to ensure precise straightening performance for many different metal sheet materials. Its compact design makes it an excellent solution for systems requiring sensitive preliminary straightening before being driven.

When additional straightening is required before switching to a new product line or in case of sheet metal change, our Decoiler with Straightener is the perfect solution. This machine is a preferred addition to currently running systems and is especially useful whenever there is a foreseen sheet change. By using this type of decoiler, it is possible to provide openers that open the sheets in different sensitivities without interfering with the driver.

In conclusion, our Hydraulic Decoiler Straightener is an essential machine tool for modern manufacturing and processing industries. It provides high-efficiency, precision, and reliability for various production operations, making it an excellent investment for businesses of all sizes.

Main Parts of Hydraulic Decoiler Straightener

Coil Car (Optional)

Coil Car (Optional)

● Coil car is one of the optional for the customer, It is installed on the side of the decoiler part, and can automatically feed the coil into the straightener machine accurately and fastly.

● The surface of Coil car is V type with sandblasting surface treatment process, it can protect the material surface from scratching and the main function is assisting loading the coils on the spindle rack of decoiler parts.

● Adjustable coil guide baffles prevent narrow coils from dumping

● Coil car move forward and backward by Hydraulic motor

● Coil car lifting up and down smoothly by hydraulic cylinder

● Share the power with decoiler machine

Decoiler Part

Decoiler Part

● The motor control cabinet of the material combined decoiler straightener are relatively independent,also they use their own frequency converter,that means it could take more effectively protecting the machine to make sure there will not distorted when it subjected to other external forces.

● The drive system of the straightening machine are universal joint and gear transmission,that could effectively avoid the material’s damage from passive wheel rotation.

Straightening Part

Straightening Part

● The straightening wheel have dial indicator,it could found the leveling points quickly. It strengthen roll stiffness according with straightening back pressure wheel,then make the straightening effect better.

● The service life of the machine will be longer with adding the lubrication system.OEM accepted,could change the rack load,correction parameters and also could according to the need to make power or unpowered pressure arm hydraulic expansion,etc.
