Description

Technical Field

[0001] The utility model relates to the technical field of high-power laser cutting, in particular to a beam heat insulation structure of a laser cutting machine. Background Art

[0002] The beam of the laser cutting machine spans the width of the workbench. The beam (on which a guide rail is arranged) plays a role in supporting the transverse movement of the laser cutting head. During the cutting process, the beam moves longitudinally along the longitudinal guide rail of the cutting machine, driving the laser head to perform the cutting operation of the plate in a specified area on the workbench.

[0003] Under the extreme working conditions of a large-format and high-power laser cutting machine, the continuous cutting process will cause the plate to heat up continuously, resulting in heat accumulation at the bottom of the beam. Due to the concentration of heat, the beam may be deformed, thus affecting the cutting accuracy of the whole machine, and even causing the beam to be scrapped in severe cases. In addition, the continuous laser piercing operation may cause sparks to fly everywhere, and then ignite the bellows cover on the beam.

[0004] Therefore, there is an urgent need for an effective heat insulation and protection device at the bottom of the beam to address the above problems. Summary of the Invention

[0005] For this reason, the technical problem to be solved by the utility model is to overcome the problem that in the prior art, during the long-time high-power cutting operation of the laser cutting machine, heat is concentrated at the bottom of the beam, resulting in the deformation of the beam, thereby affecting the cutting accuracy and the overall performance of the machine.

The connecting member includes a spacer sleeve, a bolt and a gasket. The two ends of the spacer sleeve are respectively abutted against the heat insulation plate and the concave surface. The bolt sequentially passes through the second connection hole, the spacer sleeve and the first connection hole to connect the heat insulation plate to the concave surface, and the bolt abuts the gasket against the heat insulation plate.

[0013] In an embodiment of the present utility model, the size of the heat insulation plate along the length direction of the crossbeam body is smaller than the length of the crossbeam body.

[0014] In an embodiment of the present utility model, the concave surface extends to both ends in the width direction of the crossbeam body, and the size of the heat insulation plate along the width direction of the crossbeam body is greater than the width of the crossbeam body.

[0015] In an embodiment of the present utility model, the gap between the heat insulation plate and the concave surface is between 15 - 25 mm.

[0034] Referring to Figure 1 as shown, a heat insulation structure for the crossbeam of a laser cutting machine of the present utility model includes:

[0035] The crossbeam body 1 is used to support the lateral movement of the laser cutting head, and a workbench is located below the laser cutting head.

[0036] The heat insulation plate 2 is installed on one end face of the crossbeam body 1 facing the workbench, and a concave surface 11 is provided on one end face of the crossbeam body 1 facing the workbench.

[0037] The connecting member 3 is arranged between the heat insulation plate 2 and the concave surface 11 to keep a predetermined gap between the heat insulation plate 2 and the concave surface 11.

[0038] It can be understood that a slide rail for the laser cutting head to slide is provided on the crossbeam body 1; a to-be-cut plate is placed on the workbench, and during cutting, the crossbeam moves longitudinally along the longitudinal guide rail of the cutting machine, driving the laser head to perform cutting operations in a specified area on the workbench. By providing the heat insulation plate 2 between the crossbeam body 1 and the workbench, an effective heat insulation barrier is formed to prevent the heat generated during cutting from being directly transferred to the crossbeam, reducing the accumulation of heat at the bottom of the crossbeam, thereby preventing the crossbeam from deforming due to heat concentration.

[0039] In one embodiment, referring to Figures 2 to 4 As shown, first connection holes 12 are distributed on the concave surface 11, second connection holes 21 corresponding to the first connection holes 12 are distributed on the heat insulation plate 2, the connecting member 3 includes a spacer sleeve 31, a bolt 32 and a gasket 33, both ends of the spacer sleeve 31 are abutted against the heat insulation plate 2 and the concave surface 11 respectively, the bolt 32 sequentially passes through the second connection hole 21, the spacer sleeve 31 and the first connection hole 12 to connect the heat insulation plate 2 to the concave surface 11, and the bolt 32 abuts the gasket 33 against the heat insulation plate 2.

[0040] In one embodiment, the heat insulation plate 2 is in close contact with one end face of the crossbeam body 1 facing the workbench.

[0041] In one embodiment, the dimension of the concave surface 11 along the length direction of the crossbeam body 1 is greater than or equal to the dimension of the concave surface 11 along the length direction of the crossbeam body 1.

[0042] In one embodiment, the dimension of the heat insulation plate 2 along the length direction of the crossbeam is smaller than the length of the crossbeam body 1.

[0043] In one embodiment, the concave surface 11 extends to both ends of the crossbeam body 1 in the width direction, and the dimension of the heat insulation plate 2 along the width direction of the crossbeam body 1 is greater than the width of the crossbeam body 1 and completely shields the bellows cover. It effectively prevents the risk of the bellows cover being ignited by sparks generated during laser perforation, improves the safety of the equipment, and reduces the fire hazard.

[0044] In one embodiment, the gap between the heat insulation plate 2 and the concave surface 11 is between 15 - 25 mm. Preferably, it is 20 mm.

[0045] In one embodiment, a baffle 22 extends from the periphery of the heat insulation plate 2 towards the workbench direction, further expanding the heat insulation protection range.

[0046] In one embodiment, a plurality of heat insulation plates 2 are arranged along the length direction of the crossbeam body 1, and adjacent heat insulation plates 2 are in close contact with each other. It is convenient for modular adjustment according to the length of different crossbeam bodies 1, adapts to laser cutting machines of different sizes, and has strong versatility and flexibility.

[0047] In one embodiment, the heat insulation plate 2 is made of a material with a relatively low thermal conductivity, such as stainless steel. Stainless steel has good high-temperature resistance and corrosion resistance characteristics, ensuring that the heat insulation plate 2 can still maintain structural stability in a high-temperature environment, extending its service life and reducing maintenance costs.

[0048] In one embodiment, a sealed air duct is formed between the heat insulation plate 2 and the concave surface 11, and the sealed air duct is connected to an axial flow fan installed on the crossbeam body 1, and the airflow generated by the fan is used to take away the radiant heat at the bottom of the crossbeam.

[0049] Principle of the present utility model: The heat insulation plate 2 is installed between the crossbeam body 1 and the workbench, forming a physical barrier, so that the heat generated during the cutting process cannot be directly conducted to the crossbeam. The heat insulation plate 2 itself is made of a material with a relatively low thermal conductivity, which can effectively slow down the heat transfer speed, reduce the heat diffusion to the crossbeam body 1, and prevent the crossbeam from being deformed by heat.

[0050] In addition, a certain air gap (a gap of 15 - 25 mm) is provided between the heat insulation plate 2 and the crossbeam body 1. Air itself is a good heat insulator, and the air gap further enhances the heat insulation effect because the thermal conductivity of air is relatively low, which can effectively slow down the heat transfer to the crossbeam body 1 by conduction. Moreover, the air gap can help with heat dissipation, taking away part of the heat, thereby reducing the temperature of the crossbeam body 1.

[0051] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present utility model and are not restrictive. Although the present utility model has been described in detail with reference to the examples, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
