CL Type Straightener Cum Decoiler 

Cradle type decoiler cum straightener.
In coil cradle instead of expandable mandrel the coil is placed on driven
rollers with adjustable side plates for centering. The side plates are
optionally provided with side rollers for prevention of damage in sides for
delicate coils.

Specification:

Features

1、Material decoiler and straightener function together in one structure ,does
not take up too much space.
2、Suitable for various of metal coils uncoiling and straightening .
3、It can adopt variable speed device , to control the discharge speed.
4、The material rack and straightener are integrated, chain drive,
chrome plated roller, special endless speed change device controls the
discharging speed, with strong durability.
5、The uncoiling adopts splint on both sides, driven by the feeding roller,
which is pulled by leveling part to control the speed.
6、Leveling roller adopts chromium steel 40CR,after conditioning ,high
frequency quenching ,hard chromium plating. Surface hardness HRC60
degree,chrome  plating thickness unilateral 0.05mm，high hardness, strong
durability.
7、Leveling adjustment adopts four independent fine-tuning, which is controlled
by scale, simple and practical.
8、Use L type iron frame induction frame induction,Mainly suitable for the
material is lighter and smaller, the surface requirements are not high stamping
production,It is often used with air feeder, with an economical punching
automatic production line.

Structure

·The head of straightener

1、The head adopts design of parallel roller, the upper 3 rollers/lower 4
rollers, totally 7 refined roller structure
2、Adopting four point fine adjustment ,which is more suitable for processing
high-precision products. Four point independent pressure is used to adjust the
pressure of feeding wheel for incoming and outgoing materials, which can
effectively prevent deviation and deformation of materials.
3、Support roller adopts galvanizing roller without power, material integrated
forming,surface resistance to scraping grinding, using mechanical bearings,
rotating flexible and durable.
4、It adopts cost iron hand wheel , and its surface is electroplated, it is the
most traditional hand wheel.
5、The transmission part is protected by protective cover on both sides,
equipped with window for convenient observation.
 
·Rack section
1、The equipment adopts decoiler and straightener combine together ,improve the
utilization rate of the site.
2、The rack is designed with cantilever beam, and all the plates are cut by
laser plasma, with high precision and good interchangeability.
3、All plates are cut by laser plasma with high precision.
4、The overall structure is simple, general technical workers can assemble and
replace equipment parts, convenient and fast ,greatly reduce the maintenance
cost.

·Straightener roller
1、The straightener wheel is made of solid bearing steel, thickened and
electroplated after intermediate frequency, and the surface hardness is not
low HRC58, to ensure the durability of material.
2、Forging round steel with GCr15, after preheating treatment( spheroidizing
annealing),then turning , milling ,intermediate frequency treatment , rough
grinding and cooling stabilization,then fine grinding ,finally electroplating
,maximize the gurantee of precision degree, concentricity, smoothness and
hardness , extend the service life of straightener roller. 
  
·Drive gear
The gear processing process includes the following process：gear blank
processing-tooth surface processing-heat treatment-Tooth surface finishing.
Raw parts are mainly forged parts，By normalizing treatment, improve its
cutting, to facilitate cutting;according to the gear design drawings, rough
machining, and then half fine processing ,lathe、rolling、gear shaping,make the
gear basically formed;then by heat treatment to improve the mechanical
properties.
According to the design requirements of the drawings, the final finishing,
finishing benchmark finishing the tooth type. After the above treatment, our
gear grade can reach grade 6 , high wear resistance and strength high ,long
service life.

·Power section
1 Adopt model 80 worm gear vertical reducer ,use the speed converter of gear ,
reduce the rotation number of motor to desired rotation number ,and get the
mechanism with larger torque.
2、Adopt vertical motor, low vibration, low noise, fixed rotor part adopts pure
copper coil, life is 10 times of ordinary coil, both ends are equipped with
ball bearing ,low friction, low temperature.

·Electric control box
1、Adopt silver alloy relay ,full copper coil ,flame retardant safety base,
long lasting and durable.
2、Adopt safety protection adjustment circuit time delay ,silver alloy contact
,various and dial, satisfied different delay ranges.
3、The switch adopts sliding contact ,with self-cleaning function , normally
open and normally closed contact adopts separate bonding structure, can work
with different poles, equipped with anti-rotation positioning and stop loose
mounting gasket.
4、Adopt self-duplex flat button, the force is light, the key range is
moderate, the building block type combination structure. The contact is made
up of keto-base composite points with strong conductivity and large current,
with a life span of up to 1 million times.
