Description

Technical Field

[0001] The utility model relates to a detachable laser cutting machine forging nozzle, belonging to the technical field of laser cutting machine accessories. Background Art

[0002] A laser cutting machine uses a laser beam emitted from a laser source, focused through an optical system into a high-power-density laser beam. The laser beam irradiates the surface of the workpiece, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. With the increasing demands on modern processing technology, laser cutting machines are now widely used. When using a laser cutting machine, the nozzle, as one of the essential components, is located at the bottom of the laser head, very close to the workpiece. Focused laser light and high-pressure air flow are emitted through the nozzle. The nozzle of the laser cutting machine can assist in the rapid ejection of gas, effectively preventing debris such as molten metal from rebounding upward, thereby protecting the focusing lens.

[0003] Chinese patent number: CN220145020U, mentions a detachable laser cutting machine forging nozzle, which is convenient for threading the main component on the external laser cutting machine through the threaded tube. After the connection, the auxiliary ring is screwed to make the clamping pad fit with the laser cutting machine to complete the installation, reducing the clamping effect between the main component and the laser cutting machine. When disassembling, the auxiliary ring is screwed to make the clamping pad fit the laser cutting machine, which makes it convenient to unscrew the main component from the laser cutting machine for easy operation. However, this device is not convenient for adjusting the size of the laser beam and is not convenient for adapting to various processing conditions. Now there is an urgent need for a detachable laser cutting machine forging nozzle to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figure 1-Figure 5The utility model provides a technical solution: a detachable laser cutting machine forging nozzle, comprising an outer shell 1, a nozzle 2, a mounting plate 6, a column 11, a first blocking block 12 and a second blocking block 13. The outer shell 1 is hollow in design, and a first threaded column 7 is installed in the middle of the upper part of the mounting plate 6. The mounting plate 6 is installed above the outer shell 1 through a plurality of first bolts 8. A through hole 3 is opened through the middle of the front side of the outer shell 1, and an extension shell 19 is installed in the middle of the upper part of the nozzle 2. A second threaded column 21 is installed in the middle of the upper part of the extension shell 19. The first threaded column 7 and the second threaded column 21 are respectively hollow in design, and the annular side of the column 11 is symmetrically provided with a first through groove 16 and a second through groove 22. The two first through grooves 16 and the two second through grooves Magnetic sheets 18 are symmetrically installed on the inner bottom surface of the groove 22, and two first blocking blocks 12 and two second blocking blocks 13 are respectively provided. Magnetic plates with opposite magnetic properties to the magnetic sheets 18 are respectively installed under the two first blocking blocks 12 and the two second blocking blocks 13. First through holes 14 are respectively opened through the top of the two first blocking blocks 12, and second through holes 15 are respectively opened through the top of the two second blocking blocks 13. Through slot holes 17 are respectively opened through the inner bottom surfaces of the two first through slots 16 and the two second through slots 22. The column 11 is rotatably connected to the inner wall of the outer shell 1 through a bearing, and the diameters of the multiple through slot holes 17 are respectively equal to the diameter of the nozzle 2. This design solves the problem that the original device is inconvenient to adjust the size of the laser beam and is not convenient to adapt to various processing conditions.

[0021] As the first embodiment of the present utility model: a square plate 10 is mounted on the front side of the column 11 by means of a plurality of second bolts 9. By mounting the square plate 10 on the front side of the column 11 by means of a plurality of second bolts 9, the square plate 10 and the rotating shaft 5 can be easily disassembled. A rotating shaft 5 is mounted on the front side of the square plate 10. The rotating shaft 5 is concentrically arranged with the through hole 3. A turning handle 4 is mounted on the front end of the rotating shaft 5. By concentrically arranging the rotating shaft 5 with the through hole 3 and mounting the turning handle 4 on the front end of the rotating shaft 5, the rotating shaft 5 can be easily rotated. The turning handle 4 is made of a heat-insulating material. By making the turning handle 4 of a heat-insulating material, heat can be easily isolated. Reinforcing ribs 20 are symmetrically arranged between the second threaded column 21 and the top of the extension shell 19. By symmetrically arranging the reinforcing ribs 20 between the second threaded column 21 and the top of the extension shell 19, the second threaded column 21 and the extension shell 19 are more stable. The second threaded column 21 is communicated with the lower portion of the outer shell 1 and is threadedly connected thereto. By communicating with the lower portion of the outer shell 1 and threadedly connecting the second threaded column 21 , it is easy to disassemble the second threaded column 21 .

[0022] As the second embodiment of the present utility model: when it is necessary to use this device, first determine whether it is necessary to limit the size of the laser beam. If necessary, the multiple first bolts 8 can be removed, the mounting plate 6 can be opened, and then the two first blocking blocks 12 and the two second blocking blocks 13 can be placed in the corresponding first through grooves 16 or second through grooves 22. At this time, the multiple magnetic sheets 18 will be magnetically attracted to the magnetic plates under the two first blocking blocks 12 and the two second blocking blocks 13. Then the mounting plate 6 is reset, and then the device is installed on the laser cutting machine through the first threaded column 7. Then, the position of the two first blocking blocks 12 or the two second blocking blocks 13 is adjusted by rotating the handle 4, so that the two first through holes 14 or the two second through holes 15 are concentric with the first threaded column 7 and the second threaded column 21. At this time, the laser is emitted, and the beam diameter will be blocked because it is different from the diameter of the two first through holes 14 or the diameter of the two second through holes 15, thereby changing the size of the laser beam. Specific adjustment can be made by rotating the handle 4.
