Description

Technical Field

[0002] Waterjet cutting, also known as water jet cutting, is a high-pressure water jet cutting technology. It is a machine that uses high-pressure water jet cutting. Waterjet cutting is gradually becoming the mainstream cutting method in industrial cutting technology.

[0003] Waterjet cutting has the following advantages: 1. Wide range of cutting. It can cut most materials, such as metal, marble, glass, etc. 2. Good cutting quality. Smooth cuts without rough, burred edges. 3. No heat processing. Because it uses water and abrasives for cutting, no heat (or very little heat) is generated during the processing. This effect is very ideal for materials affected by heat, such as titanium. And it can be used in special working environments, such as underground coal mines. 4. Good environmental protection. It uses water and sand for cutting. This sand will not produce toxic gas during the processing and can be discharged directly, which is more environmentally friendly. 5. No need to change the tool or the cutting machine device. One nozzle can process different types of materials and shapes, saving cost and time. 6. Flexible cutting. There is no restriction on the cutting direction, and various cutting shapes can be completed.

The installation sleeve 3 is installed in transition to achieve the convenience of disassembly and assembly.

[0029] The limiting seat 4 is threadedly connected to the outer side of the mounting sleeve 3. By rotating the limiting seat 4, the gap between the limiting seat 4 and the outer ring 22 can be flexibly and accurately adjusted to achieve convenient water cutting of circular holes with different diameters.

[0030] Furthermore, in order to increase the friction force of the rotation of the limiting seat 4 and prevent slipping, the outer ring of the limiting seat 4 is provided with anti-slip protrusions.

[0041] The waterjet gun fixing device is fixed to the object to be cut by at least two adsorption seats 6 during circular hole waterjet cutting. The first slide bar 5 is supported and connected to the adsorption seat 6 by the support frame 7. The cutting gun 1 is held at the rear and rotated so that the limit seat 4 is always in contact with the outer ring 22, thereby realizing the precise circular motion of the cutting head and reliable cutting of the circular hole.
