Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic processing, in particular to a swirling pressurized water knife. Background Art

[0002] Hydrodynamic machining is a machining method that removes material by impacting the workpiece with a high-speed liquid stream. Because the commonly used liquid is water, it is commonly known as "water jet". Water jet is also called water cutting or high-pressure water jet cutting. It is a technology that uses water as a knife to cut objects by pressurizing water. It has the advantages of not changing the physical and chemical properties of the cut object, fast speed, high efficiency, and low cost.

[0003] The existing water jet pressurization methods include the booster pump pressurization method and the method of directly changing the discharge pressure of the high-pressure pump. The core component of the booster pump pressurization method is the booster pump, which is the core equipment that sends water from the water supply pipe to the water jet. The water flow can be pressurized by controlling the booster pump. In the method of directly changing the discharge pressure of the high-pressure pump, the high-pressure pump is the core equipment that directly provides the water jet pressurized water flow. If the water jet pressurization needs to be increased, the pressure of the water discharged by the high-pressure pump can be changed to achieve it. These two boosting methods require the booster pump and other equipment to be installed outside the cutting system, which will consume a lot of oil, electricity and other resources. On the contrary, if these devices are placed in the main controller box, a sufficiently large installation space needs to be provided, which not only occupies a large space, but also the distance of the booster equipment installation will determine the length of the pipeline. The longer the pipeline, the greater the energy consumption, especially in the process of boosting, which will generate a lot of noise. Utility Model Content

[0004] In view of this, the utility model aims to provide a swirling pressurized water jet to solve the problem that the pipeline of the existing water jet occupies a large space and generates a lot of noise during the pressurization process.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a swirling pressurized water knife, which includes a spiral pipe and a buffer cutter head, the water inlet of the buffer cutter head is connected to the water outlet of the spiral pipe, the inner diameter of the spiral pipe gradually decreases from the water inlet of the spiral pipe to the water outlet of the spiral pipe, and the inner cavity of the buffer cutter head is a stepped cavity structure composed of multiple trapezoidal cavities arranged in sequence from the water inlet of the buffer cutter head to the water outlet of the buffer cutter head.

[0006] Furthermore, a shell is provided on the outer side of the spiral pipe.

[0007] Furthermore, the buffer cutter head is conical, the tip of the buffer cutter head is the water outlet, and the other end of the buffer cutter head is the water inlet.

[0008] Furthermore, the inner diameter of the water inlet of the spiral pipe is 8 mm.

[0009] Furthermore, the inner diameter of the spiral pipe at the water outlet is 5 mm.

[0010] Furthermore, the inner diameter of the buffer cutter head at the water outlet is 0.1 mm.

[0011] Furthermore, the spiral pipe is made of metal.

[0012] Furthermore, the buffer cutter head is made of metal or ceramic.
