Sheet metal of bending & forming : Sheet metal bending and forming is performed on a press brake, to be formed of sheet material is placed on the bending machine, with the lift lever to lift the brake pads, the workpiece slid into place. The moving piece is lowered to the plate to be formed, and the metal bending forming process is realized by applying a force to the bending lever on the plate bending machine.
The cost of the process : standard mold cost ( none ), unit cost ( low – medium ).
Typical products : consumer electronics , Packaging, transportation, construction metal parts, etc.
Suitable for : suitable for mass production ( not more than 5000 pieces ), but also can be customized for each piece.
Quality : high bending accuracy, error is about 0.1mm (0.004in)
Speed : per minute 6 bends, but it will take longer time for the initial configuration of the bending machine
Applicable materials are suitable for almost all metal materials, the most commonly used materials are: steel, aluminum, copper and titanium and other ductile metal plates
Design considerations
1. Single piece bent length up to the 16m (52ft)
2 . Metal bending path can be a straight line
3 . Malleable material folded inside radius of the sheet thickness is doubled , hard material is The radius of the inside corner of the bend is 3 times the thickness of the sheet
4. If the metal sheet has not been heat-treated, the thickness of the bend can be up to 50mm (2in). The detailed process description (graphic text + video) The punch is driven by a hydraulic cylinder Vertical pressure), and the pressure is determined by 4 factors: bending length, plate thickness, extension force and bending radius.
Step 1 : Place the prepared sheet metal parts on the hard mold
Step 2 : The punch is driven by a hydraulic cylinder, which presses the sheet metal parts to bend and form, each bending only takes a few seconds, and the whole process is controlled by the computer
