Application of High Precision Decoiler Straightener

Combo uncoiler straightener is the first beginning of the Metal sheet stamping line, it's used the loading the coils and straightening the metal sheet strips and leading the strips into the Mechanical Power Press and Coil Servo Feeder machine.


Combo uncoiler straightener can be found in many different stamping product line such as hardware stamping line, saw blade stamping line, knives pressing line, motorcycle parts stamping line, car license plate stamping line, small auto parts stamping line, computer and electronic components stamping lines etc.


The configuration of metal sheet stamping line

Step-1: High precision decoiler straightener, Loading coil and uncoilling coil and straigthening the Coil strips.

Step-2: NC Servo Roll Feeder machine, Feed coil strips to press machine.

Step-3: Power pres machine with the progressive die,pressing to the end product

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

With pneumatic pressure on upper and lower straightener roller distance adjusting and worm gear adjusting, it can achieve precision straightening performance for many different kind of metal sheet material.

The roller is made of solid bearing steel. After heat treatment, hard chrome plating and re-grinding, it has high hardness, good abrasion resistance and long use life.

Roller leveling and feeding machine are placed on the same horizontal platform, which can reduce the feed machine and leveling error to meet the need of high precision.

This type combo uncoiler straightener machine is very popular in European countries, if you want to know more about it, warmly welcome to email us, thanks!
