Abstract
Description
Technical Field
[0001] This utility model relates to the field of water-guided laser technology, specifically to a uniform water beam generation device for water-guided lasers. Background Technology
[0002] Water-guided laser processing is a green, efficient, and novel laser cold processing technology. Its technical principle is to use a high-pressure micro-water beam as an "optical fiber." Through reasonable optical design, the laser is coupled into the water beam and guided to the surface of the material being processed. The high-pressure water beam plays a crucial role in water-guided laser processing. As the transmission medium for the laser, its quality directly affects the transmission efficiency. A stable and uniform high-pressure water beam can ensure effective transmission of the laser within the water beam and reduce energy loss. Conversely, if the water beam quality is poor, such as the presence of inhomogeneity and turbulence, the laser energy will be scattered and attenuated during transmission within the water beam, thereby reducing the transmission efficiency of the laser.
[0003] Therefore, in order to ensure the effectiveness and reliability of water-guided laser technology, it is necessary to propose technical solutions to eliminate non-uniformity and turbulence in high-pressure water jets. Utility Model Content
[0004] Based on this, and in response to the above problems, this utility model provides a uniform water beam generation device for water-guided lasers, which eliminates non-uniformity and turbulence in water flow and improves the efficiency of laser transmission.
[0005] To achieve the above objectives, this utility model provides a uniform water beam generation device for water-guided lasers, including a primary homogenizing water cavity connected to a water supply pipe for receiving and initially homogenizing water flow from the water supply pipe. A primary flow guide platform is provided inside the primary flow guide platform, the top surface of which is higher than the bottom surface of the primary homogenizing water cavity, forming a buffer zone for water level rise. Multiple primary flow guide holes are evenly distributed on the top surface of the primary flow guide platform. After the water supply pipe introduces water into the primary homogenizing water cavity, the water surface gradually overflows the primary flow guide platform and flows into the nozzle from the multiple flow guide holes on its top surface.
[0006] In one embodiment, a secondary homogenizing water chamber is provided between the primary guide platform and the nozzle to receive water flow from the primary guide hole. Multiple secondary guide holes are evenly distributed on the bottom surface of the chamber, and the water flow flows into the nozzle after passing through the multiple secondary guide holes.
[0007] In one embodiment, a secondary flow guide platform is provided inside the secondary homogenizing water cavity. The top surface of the secondary flow guide platform is higher than the bottom surface of the secondary homogenizing water cavity, forming another buffer zone for water level rise. Multiple secondary flow guide holes are provided on the top surface of the secondary flow guide platform in a uniformly distributed manner. After the water flows through the multiple secondary flow guide holes, it flows into the nozzle.
[0008] In one embodiment, the primary guide hole and the secondary guide hole are staggered.
[0009] In one embodiment, the primary guide platform is shaped as an arc, trapezoid, square, or rectangle.
[0010] In one embodiment, the secondary flow guide platform is in the shape of any one of arc, trapezoid, square or rectangle.
[0011] In one embodiment, the water supply pipe is connected to a high-pressure water circulation module, which includes a water purification device, a water circuit pressure stabilizing device, and a pulsed short-stroke plunger pump. The water purification device is used to remove impurities and microorganisms from the water to ensure the purity of the water quality; the water circuit pressure stabilizing device is used to stabilize the water flow pressure and avoid the impact of pressure fluctuations on laser transmission; and the pulsed short-stroke plunger pump is used to provide a stable high-pressure water flow to meet the requirements of laser transmission.
[0012] In one embodiment, a gas module is provided around the nozzle. The gas module includes a gas source, a gas purification device, a gas pressure stabilizing device, an air inlet, and an air jet outlet. The air jet outlet is located around the nozzle. The gas purification device is used to remove impurities and particles from the gas. The gas pressure stabilizing device is used to stabilize the gas pressure. The air inlet is used to receive gas from the gas source. The air jet outlet is located around the nozzle and is used to spray gas around the water jet to form a gas protective layer.
[0013] In one embodiment, the jet nozzle is configured to either expel air vertically downwards or blow air outwards away from the nozzle.
[0014] In one embodiment, the nozzle is made of sapphire or diamond.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This invention provides a uniform water beam generation device for water-guided lasers. Through the design of a primary homogenizing water cavity and a primary guide platform, the water flow is homogenized and stabilized before entering the nozzle. The water flow overflows the primary guide platform and flows out uniformly from multiple primary guide holes on its top surface. This process helps to eliminate non-uniformity and turbulence in the water flow, making the water flow entering the nozzle more stable and uniform. The water beam can maintain high stability and uniformity during transmission, thereby reducing laser energy loss and improving laser transmission efficiency. Attached Figure Description
