Cold rolling machines use multiple stationary rolls to bend metal continuously at room temperature. The advantage of this method is that the steel can be produced without heating, reducing production processes and time.
The fixed rolls are arranged in groups, each group bending the metal more than the previous one. When the sheet enters the roll-forming machines, these fixing rolls act as both fixing and bending rolls.
Also known as progressive processing, this method of processing ensures the accuracy of the workpiece and is used at speeds of 30 to 600 feet per minute, often for high-volume production and the production of very long parts.
And as more demands are placed on the work of cold roll forming machines for additional machining requirements such as punching, stamping, bending, locking, and even in-line welding operations, LMS cold roll forming machines are upgraded and applied to meet these demands, ensuring that parts are produced in a single pass and ensuring increased productivity. Meeting the need for practicality.
[Cold Roll Forming Machine Component]
A basic roll-forming machine has a line that can be divided into four main sections.
The first part is the inlet part where the material is loaded. The material is usually inserted in sheet form or fed from a continuous roll. The next section, the station rolls, is where the actual roll forming takes place, where the stations are located, and where the metal is formed throughout the process. Station rolls not only shape metal but are the main driving force of the machine.
The next part of the basic roll-forming machine is the cut-off press, which cuts the metal into predetermined lengths. Due to the speed at which the machine works and the fact that it is a continuously working machine, flying die-cutting techniques are not uncommon. The final section is the finished product outfeed, where the finished product leaves the machine onto a roller conveyor or table, where it is moved manually.
- Infeed Section: This section is mainly used for loading and feeding the material, which is mostly in the form of continuous cut sheets or in continuous coils depending on the final product to be processed.
- Roll Forming Section: This section is mainly for the processing of the incoming sheet. It contains a roll-forming system with multiple rollers, as well as drives, power systems, and infrastructure. The main purpose is to continuously process the profiles that pass through the roll-forming section to achieve the desired metal component.
- Shearing Section: After the continuous processing of the profile, the profile is cut to the required nominal length according to the specified length.
- Output Section: After the complete processing procedure has been realized, to prevent the finished product from falling, a table is added to carry out the storage of the finished profile.
- Control System: A PLC control system is used to achieve a fully automated production mode and to realize processing accuracy and cutting precision.
- Additional Unit: When carrying out production, there may be many additional needs, such as printing logos, straightening, embossing, etc.
[The benefits of Cold Roll Forming Machine]
Highly Customisable: different processing molds can be used and logos can be printed on the surface during the process.
Smooth Processing: the use of progressive processing does not damage the material and reduces the scrap rate.
Long Processing Workpiece: the longest plus length of the profile processing is 30 meters.
Functional Versatility: equipped with a number of functions such as welding, bending, locking, and punching.
High Production Speed: 30-600 feet per minute production speed, extremely high production efficiency.
High Precision: PLC control is used, which greatly improves the machining precision of the parts.
