Press brakes are widely used for the precision bending of sheet metals and form pre-programmed bends between the die and the punch . The process makes a variety of shapes ( such as a 90 ° rib form ; V bottom ; channel ; closing ; double form ; hat channel ; offset etc .). A press brake bends metal by lowering a punch onto sheet metal that has been positioned on top of a die . The workpiece is clamped between matching punch and die to form a pre-set bend .
There are several types of press brakes ( such as pneumatic , servo electric , hydraulic and mechanical ). The bending length of a press brake is the maximum possible length of a metal sheet which can be bent . The press brake ’ s bending force , known as tonnage , determines how much pressure can be applied by the punch during a bend . Higher tonnage allows for bending thicker and harder metals , and lower tonnage is most appropriate for thinner metals .
“ Customisation is a key requirement for press-brake customers to produce components with different shapes , sizes and features with no need for redesign and set-up time . Smaller batches are becoming more prevalent , and manufacturers need to be able to switch from big to small runs with maximum flexibility without sacrificing productivity ,” commented Italian manufacturer , Prima Power .
