What is cold roll forming machine?
Cold roll forming machines are used to form high-strength steel components at room temperature, also known as cold rolling, and are often used to process long lengths of metal to produce a variety of metal products including (lift rails, shelving etc.). The cross-sectional profile of the cold roll forming machinery is usually tailored to the specific needs of the customer. The forming kun is used to control the localised processing of the material to prevent folding and wrinkling during the process. The machine is designed to meet the needs of metal bending.
How do roll forming machines work?
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 machine for additional machining requirements such as punching, stamping, bending, locking and even in-line welding operations, our 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 components
- 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.
- Exit Section: After the complete processing procedure has been realised, 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 realise the processing accuracy and cutting precision.
- Additional Kit: When carrying out production, there may be many additional needs, such as printing logos, straightening, embossing, etc. We offer professional straightening machines, as well as embossing machines. This ensures that the workpiece is formed in a single pass.
What is the difference between hot-rolled and cold-rolled?
The difference between hot rolling and cold rolling can be seen in the name. Hot rolling refers to the processing of metal materials manufactured in a heated environment, while cold rolling refers to the processing of metal materials at room temperature or close to room temperature, cold roll forming is obviously a more economical and efficient production method in terms of productivity.
Roll Forming Machine Tolerances
Roll forming machine tolerances are unavoidable, so generally when purchasing a cold roll forming machine, we specify the tolerances on the cross-sectional profile drawing. There are a variety of factors that determine the tolerances of parts produced by this type of machinery, including material type, size, thickness, production wear and tear, etc. This is inherent to the machine, so when we purchase a cold roll forming machine, we must not hesitate because of the presence of tolerances.
The many benefits of roll forming machines
Highly Customisable: different processing moulds 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 at 30 metres.
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.
How to keep the forming machine working properly?
After purchasing a cold roll forming machine, we need to take proper care of it so that it can continuously create value for us. So how to carry out reasonable maintenance on it?
1 . Rollers: rollers play a role in shaping the profile, is the core component of the roll forming machine, so we need to regularly lubricate it and anti-rust treatment.
2 . Cutting Knife: in the production process, because it has been in a working state, so the knife wear is also very strong, so we need to lubricate it every half a minute to prevent the knife damage caused by working for too long.
3 . The Transmission Mechanism: the transmission mechanism is also the core components of cold-forming, this piece of processing has been working state, and thus the wear and tear is also very serious, so we need the transmission mechanism every half a minute for lubrication treatment.
4 . Environment: at room temperature to work, do not use in too cold or too hot environment, to keep the surface of the machinery clean.
