How To Making Roll Forming Machine?

Making Roll Forming Machine

Roll forming is ideal for producing parts with long lengths or in large quantities.  It can also produce parts of multiple lengths from the same tooling.  Virtually any material that can be formed using sheet forming techniques can also be roll-formed.  Roll forming may also be an excellent solution whenever the consistency of the cross-sectional profile is critical.

Cold rolling is a process by which the sheet metal or strip stock is introduced between rollers and then compressed and squeezed.  The amount of strain introduced determines the hardness and other material properties of the finished product.

Roll forming is the most economical production process for the continuous bending of metal channels, angles, and complex shapes with multiple bends.  It is a cold-forming process that gradually bends flat metal into a finished, uniform profile by passing it through a series of mated tool dies.

Steps to customize a machine

1.Confirm Metal Profile Drawing

Determine the product profile drawing you need,product material and thickness, production speed,whether you need to punch hole,Electrical components brand,voltage,Machine low configuration and high configuration requirements,Factory size，Freight and packing size and so on.

2.Confirm roll forming machine configuration 

After the pattern is determined, the parameters of the machine can be determined, including the below

3.Confirm Metal Profile CAD and Roll Forming Machine CAD

After the roll forming machine parameters are determined, the engineer will draw the CAD of the model drawing according to the customer's model drawing. At this time, the customer needs to confirm that the model drawing is correct. Then the engineer will draw the machine structure drawing, and then confirm with the factory and dock the production details.

4.Prepare Machine Parts and Accessories and Assemble

5.Test machine

1. Check the performance of the machine, including the speed of the machine and whether the operation is smooth

2. Product testing: test whether the size and cutting edge of the product are smooth under the thickness and material requirements.

3. Recording machine use process and PLC
