Carbon Square 380v Cold Rolled Steel Machine Welded Pipe Making

Crane Span Structure Cold Forming Sectional Steel Cold Rolled Steel Machine
 
Function and Structure
Cold rolling steel equipment series is according to the different needs of customers, through the method of cold rolling various shapes of steel. The generalized cold-formed steel equipment includes open-end cold-formed steel equipment and closed-end cold-formed steel equipment. The cold-formed steel section equipment introduced here refers to open-formed cold-formed steel section equipment.
 
Function and structure:
The molding of profiles of various specifications, using independent casting frame (tempering treatment), base using welding structure, after stress removal treatment. The molding machine adopts an independent archway structure, universal joint shaft drive. Inlet guide device; High-quality carbon steel roller; It is easy to adjust and operate. Roller process design using imported software, computer design.

Step1: Uncoiler
Uncoiler the function is to support and expand the strip, so strip can enter into machine to roll forming. Strip can be expanded by hydraulic or pneumatic and uncoiler can be rotated 180 degree. Strip expand speed can be adjusted, braking device designed with pneumatic or hydraulic cylinder to press the brake rubber block

Step2: Shear & end welding
It is used to shear the head and the end of the steel strip of two steel coils, cutting off the irregular part then welding two steel strips, so machine can work continuously.
Step3: Accumulator
Installed between shear & end welder and forming mill, horizontal spiral accumulator store a large amount of strip in a reasonable footprint space to give enough time for shear & end welder to cut and join the ends of two successive coils with non-stop tube mill
It has vertical cage type accumulator for small size tube mill

Step4: Forming
The function of this part is to make the steel strip become to the tube blank by forming rollers

Step5: welding & scarfing
The function of this part is to center the welding seam and guide the tube blank to welding device, so the welding seam will be closed before welding, use scarfing tool to remove the burr to ensure the smooth welding

Step6: Sizing
The function of this part is used to finish the tube blank from the forming machine, so the tube size can meet the physical dimension as customer required, form to square and rectangular and other shape profiles

Step7: Straightening
4 rolls turk head straightening, straighten pipe online to achieve the ideal flatness

Step8: Cut off saw
Cut off the pipe with required length, length of pipe can be set
With option of cold saw and flying saw

Step9: Run out table
This unit is to convey the finished pipe to packing, pipe transmit by dynamic roll. A signal sensing device installed in the end of run out table, when pipe touch the signal sensing device, it will feedback the signal to control panel, control panel start working and discharge the pipe

 

 
Advantage
Cold Rolled Steel Machine. It can produce all kinds of cold-formed steel products with a circumference of 2200mm, such as a square tube, open section steel, irregular section steel, etc. The thickness of finished products is 22mm max, and the material is Q345 (or customized)

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.
