Water cutting knife nozzle and driving device for driving water cutting knife nozzle

Abstract

The invention discloses a water cutting knife nozzle and a driving device for driving the water cutting knife nozzle. The device comprises a support frame, a knife rest, a knife adjusting mechanism and a knife rest adjusting mechanism, wherein one end of the knife rest is in sliding fit with a positioning rod of the support frame, and the knife rest is laterally perpendicular to the support frame; a horizontal lead screw of the knife adjusting mechanism penetrates through the knife rest to be matched with a knife holder; a vertical lead screw of the knife rest adjusting mechanism penetrates through the support frame to be matched with the knife rest; a servo motor drives the horizontal lead screw to rotate to drive the knife holder to linearly move horizontally; and a stepping motor drives the vertical lead screw to rotate to drive the knife rest to ascend and descend. According to the water cutting knife nozzle and the driving device for driving the water cutting knife nozzle, the problems that when a knife of original water flow cutting equipment is adjusted, the initial cutting point and height are not accurately adjusted through manual movement and the labor intensity is high are solved; and the water cutting knife nozzle has the advantages of being simple in structure, capable of accurately positioning the initial cutting point and cutting height of a water cutting knife, free of manual movement of the knife, low in labor intensity, high in efficiency and easy and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of water cutting, and relates to a spray head of a water cutting knife and a driving device for driving the spray head of the water cutting knife. Background technique [0002] When the water cutting equipment is cutting the object, the water cutting pump is used to pump the mixture of water and sand to the water cutting knife, and then a high-speed jet is formed at the edge of the knife to cut the object. According to the different materials and thicknesses of the cutting objects, the height of the cutting knife needs to be adjusted so that the edge of the cutting knife is kept at a certain distance from the surface of the object. Secondly, according to the size and cutting specifications of the object, the starting point of cutting needs to be adjusted so that the cutting can be done once. Sexual completion, to avoid re-positioning the cutting point midway. In view of the above-mentioned water cutting pro...

AI Technical Summary

Problems solved by technology

In view of the above-mentioned water cutting process, the distance between the cutting knife and the surface of the object is manually adjusted at present, which is difficult to adjust accurately. Manually moving the water cutting knife to locate the cutting starting point requires frequent movement of the water cutting knife, which is labor-intensive and low in efficiency.
