Numerical control punch in the development of sheet metal processing, some customers reflect that there will be sheet metal deformation problems, not only will endanger the accuracy of the workpiece, and for the application will also lead to some harm, so how is the sheet metal deformation caused, how to prevent in the application.
In view of the situation of numerical control punch to avoid plate deformation, we should punch every hole, and then go back to punch the remaining holes. Although there will be stress, it will reduce the stress accumulation when stamping in the same direction sequence, and also make the stress of the two groups of holes cancel each other, so as to avoid the deformation of CNC punch plate.
CNC punch press starts according to the power frequency, which will produce strong vibration to the motor or the connected mechanical shaft or transmission gear. This kind of vibration will further increase the mechanical wear and loss, reduce the service life of punch components and its motor. In addition, the frequency conversion operation can also be used in the similar filling line to avoid bottle overturning or damage. The frequency conversion and speed change of CNC punching machine can run at zero speed and speed up smoothly according to the customer's requirements, and can select its acceleration curve.
It is assumed that many holes are punched on a plate because the plate is not leveled. It is likely to deform the nearby material, resulting in tensile stress on the upper surface and compressive stress on the lower surface.
In order to prevent the sheet deformation of CNC punch, it is necessary to grasp the proper operation method and processing method of the equipment, so as to make the workpiece processing more successful, more accurate and effectively improve the work efficiency.
