How to calculate the pressure or tonnage of the bending machine
Formula is: T = (65 * H2 * L) / W, where H is the thickness, in mm; L for the board length, unit m; W for the slot, unit mm, generally take plate thickness of 8 times.
It is in the ordinary relief valve (high. Medium. Low) based on the proportion of the electromagnet. Or the proportion of electro-hydraulic institutions.
The overflow of the bending machine is achieved by the NC-controlled proportional (electromagnetic) relief valve. Depending on your bending procedure, calculate the size of the pressure.
