[0002] As a common processing method today, laser processing is widely used in the processing of various metal parts due to its high intelligence and high processing precision.

[0003] Laser processing refers to heating the workpiece with a high-energy laser beam, melting the workpiece surface, and blowing away the slag with a high-speed fan to complete the cutting. Today's laser processing mostly uses the workpiece to be placed on the support plate group of the workbench. When facing ultra-high power processing (such as 80kw), the workpiece will transfer heat to the support plate group after being heated, which will cause the temperature of the support plate group to rise sharply, resulting in severe thermal deformation and softening, and then causing support failure. At the same time, the deformed support plate group will also have an adverse effect on the processing accuracy of the workpiece, so it needs to be improved. Summary of the invention

DETAILED DESCRIPTION

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments, wherein the same components are represented by the same reference numerals.

[0023] like Figure 1-3 As shown, a support plate group for 80kw laser processing includes a mounting plate 1. The mounting plate 1 is provided with a plurality of mounting stations 2 along the length direction. Both ends of the mounting plate 1 form mounting ends and are connected to a workbench. This part is any connection method that can achieve a fixed connection in the prior art, and will not be elaborated here. A V-shaped air duct 3 is formed between adjacent mounting stations 2, a retention area 4 is formed at the bottom of the air duct 3 and condensate 5 is retained, and an air inlet 6 and an air outlet 7 are formed at both ends of the air duct 3, respectively.

[0024] Preferably, a support plate 8 is also included, a pointed end is formed at the upper end of the support plate 8 for supporting the workpiece, a condensation chamber 9 is formed inside the support plate 8, and connecting ports 10 are formed on the support plate 8 corresponding to the air inlet 6 and the air outlet 7. When the support plate 8 is connected to the installation station 2, the two connecting ports 10 are connected to the air inlet 6 and the air outlet 7 respectively.

[0025] Preferably, a fan unit is also included, which is connected to the air inlet 6 and is used to transport airflow into the air duct 3 to drive the condensate 5 into the condensation chamber 9.

[0026] Specifically, the fan unit is any positive pressure blowing device in the prior art, which will not be described in detail here.

[0027] When in use, the fan unit is connected to the air inlet 6 corresponding to the end through a pipeline, and conveys airflow into the air inlet 6. The airflow moves through the V-shaped air duct 3 and flows through the retention area 4, so that a small amount of condensate 5 can be driven by the airflow to enter the condensation chamber 9 along with the airflow. That is, after the airflow passes through the retention area, the airflow carries water vapor, which contacts the support plate 8 in the condensation chamber 9 to condense on the inner wall of the condensation chamber 9. The condensed water droplets naturally flow back to the retention area 4 along the condensation chamber 9 to complete the effect of repeated condensation. At the same time, the airflow passes through the condensation chamber 9 and enters the next air duct 3 to complete the cooling and heat dissipation effect of the entire support plate 8 group.

[0028] At the same time, due to the flow of the airflow itself, the heat dissipation of the support plate 8 can also be improved to avoid heat accumulation on a single support plate 8 .

[0029] At the same time, the heat of the support plate 8 can be largely absorbed by condensation to achieve a good heat dissipation effect.

[0030] Preferably, two reinforcing plates 11 are symmetrically arranged in the condensing chamber 9 , a main channel 12 is formed between the two reinforcing plates 11 corresponding to the condensing chamber 9 , and secondary channels 13 are formed on both sides of the two reinforcing plates 11 , and an opening is formed between the upper ends of the reinforcing plates 11 and the condensing chamber 9 .

[0031] By setting the reinforcing plate 11, the airflow can enter the condensation chamber 9 through the main channel 12, so that the water droplets formed after condensation slide down along the side side channels 13, thereby being isolated from the subsequent airflow to avoid the defect that the water droplets cannot be recovered due to the push of the subsequent airflow.

[0032] At the same time, the provision of the reinforcing plate 11 can improve the overall strength of the supporting plate 8 to reduce thermal deformation.

[0033] Preferably, a rubber tube 14 is symmetrically arranged in the air duct 3, and support rings 15 are provided at both ends of the rubber tube 14 and connected to the air duct 3 through the support rings 15. A connecting groove 16 is formed on the inner wall of the air duct 3 corresponding to the auxiliary channel 13. When the reinforcing plate 11 is connected to the mounting plate 1, the connecting groove 16 and the auxiliary channel 13 are connected to each other.

[0034] The rubber tube 14 and the support ring 15 can absorb vibrations through the elasticity of the rubber tube 14 after the air flows through, thereby greatly reducing the vibrations caused by the air flow moving in the air duct 3, thereby ensuring the overall stability of the support plate 8 group.

[0035] At the same time, the setting of the receiving groove 16 can cooperate with the rubber tube 14 to facilitate the collection of the condensed water droplets, that is, to avoid the influence of subsequent airflow on the recovery of water droplets.

[0036] Preferably, the air duct 3 is provided with a limiting groove 17 corresponding to the support ring 15, and the two support rings 15 are respectively located in the limiting grooves 17 on both sides, and the limiting is achieved by the elastic force of the rubber tube 14. The reinforcing plate 11 forms an extension section 18 outward, and the extension section 18 is used to insert the limiting ring to fix the support plate 8 and the mounting plate 1.

[0037] Fixing the limit rings on both sides by the elastic force of the rubber tube 14 can make the overall installation simpler and more convenient. At the same time, the setting of the extension section 18 can also improve the guiding effect of the airflow, thereby improving the overall stability.

[0038] Preferably, the installation station 2 is provided with a positioning block 19, and a positioning hole 20 is provided at the bottom of the installation plate 1 corresponding to the positioning block 19. Both sides of the support plate 8 extend outward to form a mounting surface 21, and the mounting surface 21 is connected to the mounting plate 1 by bolts.

[0039] The positioning block 19 and the positioning hole 20 can be used to pre-position the mounting plate 1, thereby cooperating with the mounting surface 21 to improve the mounting accuracy, and cooperating with the extension portion to achieve a multi-point positioning effect.

[0040] When the laser processes a batch of workpieces, only the support plate 8 at a specific position will be heated due to the consistent position of the workpieces. As a result, after the airflow is driven, a small amount of water vapor will be continuously carried into the next air duct 3, resulting in different amounts of coolant in the retention areas 4 corresponding to different air ducts 3. Therefore, in order to achieve automatic averaging of the coolant, a connecting passage 22 is provided at the bottom of the mounting plate 1, and the connecting passage 22 is used to connect multiple retention areas.

[0041] By setting the connecting passage 22, when different amounts of coolant in different retention areas occur, automatic leveling can be achieved through the connecting passage 22 to ensure the cooling effect during repeated processing.

[0042] Preferably, an arc-shaped guide surface 23 is formed on the top of the condensation chamber 9 .

[0043] The arc-shaped guiding surface 23 can improve the guiding effect of the airflow, thereby reducing the impact of the airflow on the top of the condensation chamber 9, thereby reducing vibration and improving the overall installation stability.

[0044] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
