In order to eliminate the adverse effects brought by the deformation of the slide block press brake da52s,
it is necessary to compensate the deflection deformation of the slide block. The usual compensation methods are as follows:
Through compensation, the deformation of the sliding block of the machine tool is offset press brake da52s,
so as to ensure the precision of the machining joint and improve the accuracy of the workpiece.
1. Compensation mode of hydraulic cylinder:
Electro-hydraulic servo bending machine + hydraulic deflection compensation ↓
Workbench hydraulic automatic deflection compensation mechanism, it is composed of a set of oil cylinder installed in the workbench,
and each compensation location of the oil cylinder,
size is according to the slider, finite element analysis of the deflection curve design compensation table,
hydraulic compensation is by three vertical board after before, the relative displacement between the to achieve neutral version of the convex compensation,
Its principle is through the elastic deformation of the steel plate itself to achieve the bulge, so its compensation can be adjusted in the elastic range of the working table.
Tow, mechanical compensation advantages:
1. Mechanical compensation Accurate deflection compensation can be obtained over the full length of the table.
Mechanical deflection compensation is durable, reduces the maintenance frequency of hydraulic
compensation (such as oil leakage), and is maintenance-free during the life of the machine.
2. Mechanical deflection compensation because the compensation point is more,
so that the bending machine in the work of the workpiece is more able to achieve linear compensation, more can improve the workpiece bending effect.
3. Mechanical compensation is to use a potentiometer to measure the position of the returned signal,
as a CNC axis, to achieve digital control, so that the compensation value is more accurate.
