Laser cut blanks ready for folding
Before we can fold any sheet metal work we need to produce a developed blank shape. This blank has to be the correct size so that when it’s folded up it becomes the size and shape required for the customer’s drawn design. Using our Radan CAD/CAM sheet metal software we are able to simulate the component as a 3D model and then unfold the part to create the correct blank ready for folding on one of our CNC press brakes. The blanks can be CNC punched or CNC laser cut, these brackets have been laser cut using our Trumpf 3030 3KW fibre laser, a brand new machine installed in 2013 to boost the blank production capacity along side our 2 CNC punch presses. The accuracy of the blank is essential in achieving an accurately folded sheet metal bracket and the laser certainly gives us this accuracy and control over the profile finish.
Folding sheet metal brackets on a Trumpf 7036
Here are the components before they have been folded up and after. The brackets are relatively simple with just 4 x 90 degree bends which have all been created with the same V block and blade tooling. The CNC program to fold up the brackets has been written at the machine and then saved away onto our company computer network for recall at a later stage if the components are manufactured again. The folding process is relatively simple using the same tooling and simply folding one bend and turning the component over and then bending again to create the Z shapes seen in the photograph.

And the final folded brackets stacked ready to be packed up and sent off to the zinc platers for treatment. These folded sheet metal brackets are typical of the smaller parts we often manufacture here at V and F Sheet Metal on our Trumpf 7036 CNC press brakes.
If you have a sheet metal design that needs folding up be it 0.7mm mild steel brackets, 2mm stainless steel angle brackets, 3mm aluminium chassis components etc. please give us a call on 01489 577786 and we will be happy to chat through your idea with you. Or perhaps you have a drawing you want to send to firstname.lastname@example.org and our engineering team will be happy to review it and produce a range of price options for you.
