Description

A Cutting Device for Uneven-surface-thickness Board Based on Premixed Abrasive Water Jet
Field of the Invention
The present invention relates to the technical field of mechanical device design based on abrasive water jet, in particular to a cutting device for uneven-surface-thickness board based on premixed abrasive water jet.
Description of the Related Art
Water jet is a high-speed water flow with different shapes formed by nozzle outflow, and the speed of the jet flow depends on the pressure drop caused by the sectional difference between the front and the back of the nozzle opening. The water jet is the simplest form of energy transformation and application. Usually, a certain amount of water is pumped to a high-pressure pipeline by the suction and discharge of a power driven pump, so as to make such water reach the nozzle with certain energy. Since the diameter of the nozzle is much smaller than that of the high-pressure pipeline, such amount of water reaching the nozzle must be accelerated if it is to flow out of the nozzle opening. In this way, the water passing through the nozzle opening is accelerated to form the water jet.
Although the existing cutting device based on premixed abrasive water jet may realize the functions of cutting and processing the uneven-surface-thickness board workpiece, such device has the problems like low processing accuracy and serious waste of jet energy, especially, the device based on premixed abrasive water jet cannot operate continuously for a long time due to the limitation of the volume of abrasive tank, and the waste of jet energy further shortens the cutting time. Some cutting devices based on premixed abrasive water jet cannot adjust the standoff distance between the jet gun and the board workpiece and the moving speed of the jet gun in real time according to the bending degree and the thickness of the workpiece, which cannot guarantee the cutting quality of the uneven-surface-thickness board workpiece, thereby seriously affecting the cutting efficiency and the workpiece processing quality. Some cutting devices based on premixed abrasive water jet can realize neither the in-parallel operations, i.e., the synchronous movement of servo and control, nor the function of accurately adjusting the jet parameters of the jet gun. Other cutting devices based on premixed abrasive water jet are difficult to realize the function of automatically setting the cutting parameters of water jet, and cannot accurately guarantee the standoff distance of water jet, and are thus unable to meet the requirements of actual situations.
