In metal e21 press brake, electro-hydraulic servo CNC bending machine not only has higher accuracy, but also allows workers to operate more efficiently.
In addition, the v-groove opening of the lower die of the electro-hydraulic servo bending machine is customized according to the thickness of the workpiece.
In most cases, the v-groove opening needs to be more than eight times the thickness of the folded workpiece.
Multiple parts can be folded using different upper and lower dies, and the forming of one part requires multiple bending steps to complete.
Electro-hydraulic servo bending machine adopts electro-hydraulic control, adjustable slider stroke, advanced technology, is the ideal bending equipment.
(1) Determine the structural form of the hydraulic cylinder of the bending machine, including type, installation mode,
sealing form, buffer structure and exhaust method.
（2）Strength and stiffness calculation of the main parts of the hydraulic cylinder of the bending machine.
Draw hydraulic cylinder structure assembly drawing and main parts drawing. If the standard hydraulic cylinder is selected,
only the model and specification can be determined as required.
(3) Determine the connection form of the hydraulic device of the bending machine, including the valve plate, integrated block,
plug-in connection structure, hydraulic pump device and tank parts design.
