The hydraulic automatic deflection Crowning mechanism of the workbench is composed of a group of oil cylinders installed in the workbench. The position and size of each Crowning oil cylinder are designed according to the deflection ram of the ram and the workbench finite element analysis. The hydraulic Crowning realizes the bulge Crowning of the neutral version through the relative displacement between the front, middle and back three verticalplates. The principle is that the bulge is realized through the elastic deformation of the steel plate itself, so the Crowning amount can be adjusted within the elastic range of the workbench.

What is Hydraulic Crowning ?

Press Brakes have two hydraulic cylinders at two sides of the press brake frame ,The three-auxiliary hydraulic cylinder in the middle of the machine is called Hydraulic Crowning .When the upper beam is down, the auxiliary cylinder is filled with liquid oil and goes down ward.During the bending process, hydraulic oil inlet into the auxiliary cylinder, so that the upper beam generate downward deflection for compensation.Install the auxiliary hydraulic cylinder in the lower part of the worktable.

During the bending process, it generates an upward force on the worktable, which forms the automatic crowning system.

The pressure compensation device is composed of several small oil cylinders,comprising an oil cylinder, a motherboard, an auxiliary plate and a pin shaft, and a  compensating cylinder is placed on the worktable.The pressure compensation system is formed with a proportional relief valve.

What is Mechanical Crownings ?

Mechanical crowning is a kind of new deflection compensation method, whichgenerally uses a triangular oblique wedge structure.The principle is that the two-triangle wedge block with a angles, the upper wedgemoving is fixed at back gauge X-direction and can only move in Y-direction.

The CNC Controller calculates the required deflection amount according to the load force when the workpiece is bent (this force will cause deflection deformation of the ram and the workbench vertical plate), and automatically controls the relative movement amount of the convex wedge, thus effectively compensating the deflection deformation caused bythe ram and the workbench vertical plate .A set of wedges form a curve consistent with the actual deflection in the length direction of the workbench, so that the gap between the upper and lower dies is consistent during bending.
