decoiler and straightener machines and coil feeder with

Product Application

1. This big machine combines uncoiler function, straightener function, NC servo roll feeder function together, so as 3 in 1.
2. It can decoil suitable metal sheet coil, then straighten the metal sheet, then feed the metal sheet to press machine automatically, for automatic stamping processing.

Main Features

1. Flexible operation:
All the functions of the feeder are centered on the PLC and a hand-held knob. The operator can implement all the motion functions of the equipment at one location. This can save time.
2. High efficiency, strong security:
To maximize the use of mechanical action instead of manual operation, reduce unnecessary auxiliary time, improve work efficiency. Powerful auxiliary function, so that the operator can stay away from the uncoiler.
3. Easy to operate:
According to user needs, you can switch between the press or the device to control. Improve the equipment to adapt to the scope for the customer to save costs.
4. Area is reasonable:
Li Hao NCHF series is the powerful also have the most reasonable size in the industry, we can save space occupancy costs for the customers.
5. Control system compatibility:
NCHF series using a full set of Japan's Mitsubishi control system, and the standard system at home and abroad compatible, users do not need to worry about data conversion and other issues can be directly used to operate.
6. The design is harmonious and reasonable:
Li Hao's NCHF series is the first on the industry to introduce industrial design into product. Li Hao and the most well-known industrial design cooperation, while ensuring the basic performance of equipment at the same time, maximize the visibility of the equipment to improve the operational comfort.

Mandrel of uncoiler

Four pieces of plates. 
Each plate is fixed by screws very well.

Round mandrel of uncoiler

Automatic expansion, by hydraulic cylinder drive.

Ruler at plate of mandrel

It can indicate width of coil material.

Ruler at plate of mandrel

..., 400, 300, 200, 100, 0 | 0, 100, 200, 300, 400, ...
User can put coil material at center line position of this machine very easiliy.

Arm shape pressing device.

Drived by pneumatic cylinder or hydraulic cylinder.
Coil material will not become loosed.

Retainers of uncoiler 

Motor for hydraulic pump.

Powerful AC motor make sure of hydraulic pressure.

Cooling system is optional.

Motor for uncoiler

Powerful AC motor is adopted.
Cover is adopted to protect the motor.

Hydraulic cylinder for uncoiler

Hydraulic cylinder drives for automatic expansion, for mandrel of uncoiler.
Cover is adopted to protect it.

Guiding device for straigntener and feeder

While uncoiler decoil coil material, so material can get into entrance of feeder easily.

Entrance of straightener and feeder

Guiding device, let material at center line position.

Good design, safe and easy to use.

HMI controller

Touch screen and buttons.
User touch numbers and input feeding length numbers.
User touch order menu for the machine.

Dial gauge for straightener

Straightener has upper staightening rollers and lower straightening rollers.
As per various thickness of coil material, user need to adjust distance between upper rollers and lower rollers.
With the dial gauge, user can adjsut distance easily.

Gear set of straightener and feeder

Precise gear set is adopted, for high speed and high precision feeding.

Discharge exit of feeder

Rollers, limiting stopper, etc, are adopted for straight feeding also.
