Description

Technical Field

[0001] The utility model specifically relates to the technical field of arc surface cutting, in particular to an adjustable water jet structure suitable for arc surface cutting. Background Art

[0002] Waterjet, which means using water as a knife, is originally called high-pressure water jet cutting technology. This technology originated in the United States. It is used in the aerospace military industry. It is favored because its cold cutting does not change the physical and chemical properties of the material. After continuous technical improvements, abrasives such as pomegranate sand and corundum are mixed into high-pressure water to assist cutting, which greatly improves the cutting speed and cutting thickness of the waterjet. Now waterjet has been widely used in many industries such as ceramics, stone, glass, metal, composite materials, etc. At present, the maximum pressure of waterjet in China has reached 420MPa.

[0003] China Utility Model Publication No. CN 216504393 U discloses a new type of multi-degree-of-freedom water jet cutting machine, including a base, two groups of limit rods are arranged on the inner side of the base, and a screw is arranged in the middle position of the two groups of limit rods, the limit rod and the surface of the screw are connected with a moving seat, the upper end of the moving seat is installed with a rotating seat, the surface of the rotating seat is connected with a No. 1 connecting rod, the surface of the No. 1 connecting rod is connected with a No. 2 connecting rod, and the surface of the No. 2 connecting rod is connected with a connecting frame.

[0004] The above-mentioned new type of multi-degree-of-freedom water jet cutting machine rotates the No. 2 rotating rod on the No. 1 rotating rod, thereby driving the cutter head to rotate and cut. However, when cutting on a curved plate, the distance between the cutter head and the curved plate will change, causing the cutting force of the water jet to change, resulting in incomplete cutting. It is also necessary to manually adjust the strength of the water jet, which is more troublesome to use. For this reason, we provide an adjustable water jet structure suitable for curved surface cutting. The guide wheel moves along the curved surface, and under the action of the spring, the slider is pushed along the slide bar to drive the water jet to move. The distance between the water jet and the curved plate can be automatically adjusted to ensure that the cutting distance is equal to the uniform cutting strength of the water jet, thereby ensuring the cutting quality and being more convenient to use.
