A 3 in 1 uncoiler straightener feeder is a type of machine used in manufacturing processes to process and feed coiled metal strips or wires to downstream processes.

As the name suggests, it combines three functions into one machine: uncoiling, straightening, and feeding. The uncoiling function is responsible for unwinding the metal coil or spool, while the straightening function is responsible for flattening or straightening the metal strip or wire. The feeding function then pushes the metal strip or wire forward to the next process, such as a press or a stamping machine.

The 3 in 1 uncoiler straightener feeder is commonly used in industries that require high-volume production of metal components, such as automotive parts,ceiling punching,electrical accessories, and appliance manufacturing. By combining three functions into one machine, it can improve efficiency and productivity while reducing labor costs and material waste.

Features of the medium thick plate type 3 in 1 uncoiler straightener feeder:

1.The leveling roller relaxation part of the medium thick plate type 3 in 1 uncoiler straightener feeder is changed from the standard cylinder relaxation to piston cylinder relaxation, suitable for stamping, leveling and feeding of medium and thick plate coils with a thickness of 0.5mm to 4.5mm and a width of 70mm to 1800mm.

2.The main shaft of the uncoiling machine adopts a hydraulic expansion system, and the material coil drum adopts a wedge-shaped slide structure, which can automatically lock and release the coil. The material release width is adjusted by two stop rollers with screws. When releasing material, the outer stop roller is lifted by a cylinder to avoid the material, which makes material loading and unloading reliable, with low labor intensity and good safety. The feeder is equipped with a material pressing arm to prevent material from loosening, and the material release adopts a through-beam photoelectric induction system for automatic material release. The material is pneumatically supported to control the material curvature for smooth feeding.

3.The leveling roller is made of high-alloy bearing steel and undergoes a series of heat treatment processes (quenching and tempering, lathe processing, high-frequency treatment, grinding, hard chrome plating, and grinding) to strictly ensure the steel properties and surface smoothness of the leveling roller, with a dimensional accuracy of 0.01mm.

4.The two-roller clamping and feeding structure is used, and the motor drives the upper and lower clamping rollers through a reducer to feed the material head into the leveling mainframe.

5.The leveling is adjusted by four worm gears and worm screws. The hand wheel rotates the worm screw to drive the worm gear and the upper slide block for lifting, thereby achieving adjustment of the pressing amount. The hand wheel is equipped with an adjustment dial for accurate display of the adjustment amount.

6.The leveling relaxation adopts an eccentric structure, which is realized by two cylinders. During leveling, the cylinder is ventilated and the upper slide block is pressed down by the cylinder piston. During relaxation, the cylinder lifts the slide block to relax the material. Since there is a speed exhaust valve in the exhaust pipe during relaxation, the relaxation speed is fast.

7.The worm gear lifting device can adjust the feeding height within a range of 100, which is suitable for customers with different product mold heights. The adjustment is convenient, labor-saving and reliable.

Special advantages of the medium thick plate type 3 in 1 uncoiler straightener feeder:

1.The high-rigidity structural design and strict quality control procedures for processing parts can ensure the accuracy of feeding and the quality of processed products.

2.Equipped with automatic error detection device for convenient automatic monitoring during operation and safe operation.

3.The design of the upper and lower leveling rollers can be liftable, making maintenance and repair easy.

4.The feeding length and speed (Japanese Mitsubishi) can be set using a dial switch, which is easy to operate.

5.The feeding angle can be selected at 180 degrees or 240 degrees, which improves production efficiency.

6.The feeding line height adopts a turbine gear design, which can easily adjust the height (±100mm).

7.The applicable material thickness ranges from 0.5mm to 4.5mm, and the material width can reach 1600mm. The feeding accuracy is within ±0.02mm, and the feeding length can be directly input into the panel control, with a set value range of 0-9999.00mm.

Hydraulic Shearing Machine

Trimming the material’s head and tail facilitates its entry into the mold and ensures proper material collection. This machine can automatically and synchronously trim coil materials, reducing the need for manual proofreading and operation time, and improving production efficiency. For wide and thick materials, it is recommended to install additional trimming equipment.

Automatic Double-sided oil feeder

he automatic oiling system applies oil to both the upper and lower surfaces of the material, ensuring consistent lubrication and reducing the risk of friction-related defects or damage during the stamping process. This feature helps to maintain the quality of the stamped parts and extends the lifespan of the machine. Additionally, the oiling system can be easily adjusted to accommodate different types of materials, ensuring optimal performance for a wide range of manufacturing applications.

Uncoiling spindle support arm

The uncoiling spindle is supported by a hydraulic cylinder-driven support arm after loading, which balances the gravity of the main bearing and enhances the stability of the uncoiling process. This not only improves the overall performance of the machine, but also increases the service life of the spindle.

Data Table

The materials that can be processed by the machine include a variety of options such as cold-rolled sheet, hot-rolled sheet, pickled sheet, galvanized sheet, stainless steel sheet, copper, and aluminum. This wide range of compatible materials makes the machine highly versatile and adaptable to a wide range of manufacturing needs across various industries.
