Single Or Double Arm Metal Decoiler For 2-30tons Steel Coil

Uncoiler Machine Introduction:
Uncoiler is an important part of the preparation equipment before the welded pipe production line. It is mainly used to fix the steel strip and expand the steel strip to provide raw materials for the production line. Including single cone, double cone, double cone uncoiler.

Machine Characteristics:
The body of the uncoiler is welded box structure, and the frequency conversion speed regulating motor drives the drum shaft to provide the main power for the uncoiler after decelerating through the gear box. The drum of the uncoiler is a hollow shaft, supported by two bearings on the gear box, and a transmission spur gear is installed between the bearings.

The gearbox is lubricated by forced lubrication and is equipped with two constant speed motors for the closed loop oil lubrication system. The mandrel is a cantilever structure, and the front end of the mandrel is supported by the external support bearing when uncoiling to maintain the stiffness and stability of the uncoiler.



Technology
The uncoiling machine core shaft is connected with four fan-shaped plates through four end faces with oblique dove-tail grooves. Each fan-shaped plate at the end is prevented from moving axially through a radial slide, but it can achieve radial expansion and contraction.

FAQ

Q: Are you a manufacturer?
A: Yes, we are a manufacturer. We have 4 factories ( Machining, Assembling, Heat treatment, and Moulding ). We also have our own R&D department. Welcome to visit us.
Q: What kind of payment term do you do?
A: We do T/T.
Q: What info do you need before giving me the price and proposal?
A: Since we design individual machines based on our customer's requirements, we need your desired products' basic dimensions, including all the pipe diameter(or tube length), thickness range, usage, raw material steel grade, coil weight, and degree of automation.
Q: What should I do if I just start a new business?
A: Contact us immediately, we provide a free consultant for pre-sales service. Also, we can help you solve the raw material (steel coil) purchase, worker training, international market price, and more.
Q: How do you do QA?
A: We have a special team to do strict QA, this is one of our strengths:
(1)Every gearbox will be tested for 8 hours with oil inside to guarantee there is no leak.

(2)Every shaft will be inspected for centering jumpiness.
(3)Every roller will be checked to make sure it's in the range of tolerance critical parts will be inspected for all dimensions.
Q: Why I should choose you? what are the differences between you and other Chinese suppliers?
A: We are concentrating on pipe-making machines for more than 20 years. We have constructed many steady trading partners in Asia, Africa, the middle east, Europe, and South America throughout the years. Our innovative designed production line and every single unit of the production line are economical and practical.

ZTZG is one of three executive directors of 'China Steel Structure Association' 

and one of China's top ten pipe making machinery brands. 

With over 20 years of sales and R&D, ZTZG has acheived multiple China's first along with

several patents that lead the pipe making industry in China. We look foward to make

better, steadier, and more economical machines in the future.
