Secrets About Cold Roll Forming Machine

JINSHAN, China - May 20, 2018 - PRLog -- Cold Roll forming is a flexible process, where both the fundamental rules and the exceptions can be utilized. Typically a cold roll forming machine works in an automatic and continuous cycle. The material is fed into the machine where it continuously makes its way through consecutive roll forming stands (https://mtc-china.com/roll-forming-stand/), ending with the completion of a final product.

Cold roll forming machine fabricates various metal products out of long strips of metal, most commonly coiled steel. Usually, manufacturers design a specific drawing of the required cross-section profile for the machine to bend the metal as necessary. Other than roll forming, a traditional cold roll forming machine performs some other metalworking processs, including online cutting and punching.

The required metal product is always achieved through the process from decoiling, roll forming , cutting and exiting. In addition, there are many products with holes or slots needed, and in this case punching tools are necessary.

For the modern roll forming machines (https://mtc-china.com/), there are more advanced operation and more duties to be done. However,  for a traditional cold roll forming machine, it can do only the basic metal duites: roll forming and cutting.
Such basic cold roll forming machine has a line that commonly consists of five major parts.

• Entry Section. Entry section is for the material loading or feeding, and some manufacturers call it feeding guide. The material has been fed either in pre-cut sheet or from a continuous coil.
• Roll forming Section.  This section concludes rolling tools, stands transmissioning unit, power unit and the base structure. It is where roll forming and metal shaping exactly happens as it goes through the consective stands. The roll forming section doesn't just shape the metal, with electrical motor loaded, it also provides the driving force of the cold roll forming machine
• Cut-off Section. Cut-off unit is a necessary tool to cut the sheet to a pre-measured length from continuous coiled material. Flying die cut-off tool is not uncommon for some cold roll forming machine with high speed requirement.
• Exit Section. Exit station protects the finished products from dropping off to the floor.  After cutting, there is a roller converyor or table to support the finished products, which operators will take away manually after then.
• Control Section. It's a very simple control with a few buttons on it. It controls the forwarding, and backwarding of the machine. There might be buttons for manual cutting. The basic control section is necessary for manual operation of the cold roll forming machine.

Cold Roll Forming Machine Line NOW

As the age advances, people have more needs on cold roll forming machines duties. A traditional cold roll forming machine just does shaping and cutting, but today's machines have features of punching, embossing,  bending, locking and even welding on line. Besides, the apperance of cold roll forming machines has also greatly improved.  As a result, the control system has also developed based on different jobs a cold roll forming machine line usually makes.
In conclusion, the major developments on a cold roll forming machine line may list as below.

• ID Designing. The modern cold roll forming machines have various kinds of ID designing,from the transmission unit (https://mtc-china.com/roll-forming-machine-transmission/), to the roll forming stands (https://mtc-china.com/roll-forming-stand/) designing.
. Also, cooling system and safety barriers have been necessary for some machines.
• Leveling Section. Heavy duty roll forming machines are necessary to roll form more than 3mm-thickness steel.  In this case, the raw material has to enter leveling section so that they can be roll formed flat and straight.
• Punching/Pressing section.  On a basic cold roll forming machine, it's not available to punch holes or slots on line. However it's not working on modern roll forming machines.  There are not only holes or slots, but also many different punching options required, such as notching, steps, and company logos etc.
• Embossing Section. There are products that requires embossed patterns. In this case, manufacturers will add embossing rollers in the line, before, during or after roll forming.
• Locking/Welding Section. Some special products require on line locking, like rainspouts, and some has to been welded on line, seamless welded pipes for example.
• Safety Section. There are cooling system, and safety barrier on some cold roll forming machines that working mostly in Euorpean and American markets for safety reason.
• Control Section. The control section has innovated a lot based on the complicated jobs a morden cold roll forming machine does. Modern manufacturers use PLC control system, as the new 'brain',to ensure the accuracy of cutting and punching.
