Description

Technical Field

[0001] The utility model relates to the technical field of lasers, and specifically relates to an anti-freezing and cracking structure on a laser cooling pipeline. Background Art

[0002] The CO2 laser is a kind of laser with a relatively high continuous output power at present. Laser cutting is to use a laser beam with a high power density to scan the surface of the material, heat the material to several thousand to tens of thousands of degrees Celsius in an extremely short time, melt or vaporize the material, and then blow away the melted or vaporized substance from the cut with high-pressure gas to achieve the purpose of cutting the material.

[0003] Because the equipment will generate a lot of heat during operation, and because the temperature of the equipment components is too high, it will damage the equipment, which has a great impact on the stable operation of the resonant cavity, the core component of the laser equipment. Therefore, it is necessary to cool down such components.

[0004] At present, the more common method in industrial processing is to input constant-temperature cooling water to take away the heat on the equipment and control the temperature of the equipment within a constant temperature range, so as to finally achieve the purpose of stable operation of the laser equipment.

[0005] Due to the existence of various water-cooling pipelines in the equipment, the following situations exist: 1. When the equipment is shut down and encounters extremely low-temperature weather, the water freezes inside the pipeline; 2. Although the water-cooling pipeline has been drained after the equipment is adjusted, there will still be a lot of cooling water left. When transporting, if it encounters extremely low-temperature weather, the water will freeze and expand in volume in extreme weather, damaging the pipeline or equipment, resulting in irreparable losses.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment:

[0036] Please refer to Figure 1-11 , an anti-cracking structure for a laser cooling pipeline, including an inner component and a coolant transmission component.

[0037] The inner component includes an inner pipe 7, and the inner pipe 7 is a flexible hose with elasticity.

[0038] The coolant transmission assembly includes a body to be cooled 1, a plug 4, and a support pad 8. A cavity is provided inside the body to be cooled 1. An inner tube 7 is located inside the body to be cooled 1. The plug 4 is respectively used to seal the ends of the inner tube 7. Support pads 8 are provided at both ends inside the body to be cooled 1. The support pad 8 is provided with a number of through holes corresponding to the ends of the inner tube 7. The support pad 8 is flexible. The support pad 8 is in close contact with the inner wall of the body to be cooled 1. The support pad 8 is preferably a rubber pad, preferably made of silicone rubber material. The support pad 8 is installed inside the body to be cooled 1. The plug 4 is preferably located at the end of the body to be cooled 1, effectively providing the effect of supporting the inner tube 7 and being able to seal the ends of the inner tube 7. The body to be cooled 1 is hollow, preferably tubular. Only one tubular application scenario is shown in the figure, and it can be applied to different external shapes and devices, as long as it is hollow inside and the plugs 4 can be installed at both ends. By transmitting water inside the body to be cooled 1, when the cooling water encounters extremely low temperature weather, the water freezes and expands in volume, increasing the pressure inside the body to be cooled 1, squeezing at the inner tube 7, deforming the inner tube 7, and squeezing the support pad 8 at both ends of the body to be cooled 1, deforming the support pad 8. For this inner tube 7 that is enclosed inside the body to be cooled 1 and does not allow water to enter, without affecting the cooling performance and water flow rate of the device, after the water freezes and expands in volume, the ice squeezes the inner tube 7 and the support pad 8, and the deformation of the inner tube 7 and the support pad 8 provides some space, thereby reducing the force of the ice squeezing the side wall of the body to be cooled 1, avoiding the situation of damage to the wall of the body to be cooled 1, improving the structural stability at the water transmission part, and avoiding the situation where the cooling water freezes and expands in volume when encountering extremely low temperature weather, damaging the pipeline or equipment and causing irreparable losses.

[0039] Refer to Figure 1 and 6 The coolant transmission assembly further includes a thermometer 10 and a protective pad 11. The thermometer 10 is installed on the body to be cooled 1. A protective pad 11 is provided inside the body to be cooled 1. The thermometer 10 is connected to the protective pad 11. The end of the protective pad 11 facing the inner tube 7 is provided with a rounded corner. The protective pad 11 is a rubber pad. By detecting the temperature inside the body to be cooled 1 through the thermometer 10, it is further convenient for maintenance. By protecting the end of the thermometer 10 with the protective pad 11, the protection of the end of the thermometer 10 is improved, and the situation of damage to the end of the thermometer 10 is reduced.

[0040] Refer to Figure 7 The coolant transmission assembly further includes a protective window 12. A long hole is provided on the body to be cooled 1. A protective window 12 is hermetically connected to the long hole of the body to be cooled 1. The protective window 12 is made of a transparent material. A sealing strip is provided between the protective window 12 and the body to be cooled 1, and it is connected by screws to effectively achieve the hermetic connection between the body to be cooled 1 and the protective window 12. The protective window 12 is preferably a transparent acrylic plate or a glass plate. By providing the protective window 12, it is convenient to observe the situation inside the body to be cooled 1, and it is further convenient for maintenance.

[0041] Refer to Figure 1 and 2 2 , the coolant transmission assembly further includes a first support seat 2 and a second support seat 3. Both ends of the body 1 to be cooled are respectively sleeved with the first support seat 2 and the second support seat 3. The end of the body 1 to be cooled is provided with steps corresponding to the first support seat 2 and the second support seat 3. Through the arrangement of the first support seat 2 and the second support seat 3, when installing, the first support seat 2 and the second support seat 3 can be connected to external objects, which is convenient for supporting the body 1 to be cooled and is beneficial to the installation operation.

[0042] Refer to Figure 5 Figure 5 , the inner assembly further includes a transfer pipe 6. Both ends of the inner pipe 7 are communicated with the transfer pipe 6. One end of the transfer pipe 6 is communicated with the plug 4. A sealing tape is arranged at the installation place of the transfer pipe 6 and the plug 4. The arrangement of the transfer pipe 6 can facilitate the disassembly and assembly of the connection between the inner pipe 7 and the plug 4. The connection between the transfer pipe 6 and the inner pipe 7 is preferably a tension connection. After the inner pipe 7 receives a large force, part of the gas inside the inner pipe 7 can be discharged from the connection between the transfer pipe 6 and the inner pipe 7, and when not being squeezed, it will maintain the connection state to prevent water from entering the inside of the inner pipe 7.

[0043] Refer to Figure 5 Figure 5 , the coolant transmission assembly further includes a limit pipe 9. The limit pipe 9 is connected inside the body 1 to be cooled. One end of the limit pipe 9 contacts the support pad 8. The limit pipe 9 can limit one end of the support pad 8. Through the arrangement of the limit pipe 9, it is convenient to limit the position of one end of the support pad 8, reduce the situation of the position deviation of the support pad 8, and effectively position the support pad 8.

[0044] Refer to Figure 1 and 5 5 , the coolant transmission assembly further includes a pipe joint 5. The pipe joint 5 is communicated with the plug 4. The plug 4 is provided with a through hole corresponding to the pipe joint 5. The liquid transmitted can be transmitted to the inside of the body 1 to be cooled through the pipe joint 5 via the plug 4. Through the arrangement of the pipe joint 5, a longer pipeline can be connected, which is beneficial to the transmission of liquid at a distance.

[0045] Refer to Figure 4 and 5 5 , the inner pipe 7 is a silicone rubber hose. By selecting a silicone rubber hose for the inner pipe 7, the inner pipe 7 can be squeezed to deform it, effectively providing space for the increase when part of the water turns into ice.

[0046] When in use, the pipe joint 5 is communicated with the water source for transmitting water. Water is transmitted inside the body 1 to be cooled. In the case of a lower temperature, the water inside the body 1 to be cooled turns into ice, and the ice inside the body 1 to be cooled squeezes the inner pipe 7 and the support pad 8, causing the inner pipe 7 and the support pad 8 to deform.
