How to calculate the tonnage of the bending machine
Technical Guide for Bending Machines
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 a conventional bending machine is achieved by the NC-controlled proportional (electromagnetic) relief valve, which is calculated according to your bending procedure and adjusts the pressure.
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.
