[0042] See also Figures 1 to 6 , the laser cutting device provided in the embodiment of the present application is now described. The laser cutting device provided in the embodiment of the present application includes:

[0043] A bed body 1, wherein an air duct 11 is arranged in the bed body 1, and a plurality of air ports 12 connected to the air duct 11 are arranged on the outer wall of the bed body 1, and a movable damper 13 is arranged on the upper cover of the air port 12, and a through hole 131 is arranged on the movable damper 13, and the through hole 131 on the movable damper 13 can be moved to be opposite to or staggered with the air port 12, and the through hole 131 on the movable damper 13 is opposite to the air port 12 to extract smoke and dust;

[0044] The bed 1 is also provided with a guide abutment assembly 14, which includes a guide member 141 and an elastic member 142. The movable damper 13 is provided with a guide groove 132 that matches the guide member 141. The guide member 141 is inserted into the guide groove 132 and installed on the bed 1. The guide member 141 is provided with an abutment portion. The two ends of the elastic member 142 respectively abut against the movable damper 13 and the abutment portion of the guide member 141 to press the movable damper 13 against the air outlet 12.

[0045] The laser cutting equipment of the embodiment of the present application is provided with an air duct 11 and a plurality of air ports 12 connected to the air duct 11 in the bed 1, and a movable damper 13 is provided on the outer cover of the air port 12. When the movable damper 13 is moved so that the through hole 131 on the movable damper 13 is opposite to the air port 12, the internal air duct 11 can be dusted by a dust extraction device, and the waste and dust generated by the laser cutting can enter the air duct 11 from the plurality of air ports 12. Dust extraction by the plurality of air ports 12 improves the dust extraction efficiency, and the internal air duct 11 can reduce the occupied area, increase the available area of ​​other devices, and make reasonable use of the production space;

[0046] Furthermore, the guide abutment assembly 14 on the bed 1 can not only guide the movable damper 13, but also can press the movable damper 13 against the bed 1 through the elastic member 142 of the guide abutment assembly 14, thereby preventing the gap between the movable damper 13 and the bed 1 from being too large, thereby improving the dust extraction effect.

[0047] See also Figure 6 The edge of the movable damper 13 is bent away from the bed 1 to prevent the waste residue from blocking the movable damper 13 .

[0048] Waste slag generated during the laser cutting process may splash onto the edge of the movable damper 13. The edge of the movable damper 13 is bent away from the bed 1. When the movable damper 13 is moved, the waste slag can be pushed away to prevent the movable damper 13 from being stuck.

[0050] The guide member 141 in the embodiment of the present application is a screw or a threaded rod, which is inserted into the guide groove 132 and installed on the bed 1. The elastic member 142 is a spring, which is sleeved on the guide member 141. One end of the spring abuts against one of the washers 143, and the other end of the spring abuts against another of the washers 143. The washers 143 close to the movable damper 13 can abut against the edge of the guide groove 132 to provide a support surface for the elastic member 142, so as to prevent the elastic member 142 from getting stuck in the guide groove 132 and causing the movable damper 13 to move stuck.

[0051] The bed 1 is further provided with a damper driving member 15 , which is transmission-connected with the movable damper 13 to drive the movable damper 13 to move so that the through hole 131 on the movable damper 13 is opposite to or staggered with the air outlet 12 .

[0052] The damper driving member 15 in the embodiment of the present application can be a motor, a cylinder or an electric cylinder, preferably a cylinder, which is mounted on the bed 1, and the driving shaft of the cylinder is in transmission connection with the movable damper 13, and the cylinder drives the movable damper 13 to move on the bed 1, so that the through hole 131 of the movable damper 13 is opposite to or staggered with the air outlet 12. When the through hole 131 of the movable damper 13 is opposite to the air outlet 12, the external exhaust gas can enter the air duct 11 through the air outlet 12, and when the through hole 131 of the movable damper 13 is staggered with the air outlet 12, the movable damper 13 closes the air outlet 12, and the external exhaust gas cannot enter the air duct 11 from the air outlet 12.

[0053] See also Figure 2 The bed 1 includes a left wall panel assembly 16, a right wall panel assembly 17, a support assembly 18 and a plurality of reinforcement assemblies 19. The left wall panel assembly 16 and the right wall panel assembly 17 are arranged relatively to each other. The two ends of the support assembly 18 are respectively connected to the left wall panel assembly 16 and the right wall panel assembly 17. The two ends of the reinforcement assembly 19 are respectively connected to the left wall panel assembly 16 and the right wall panel assembly 17 to enhance the bending resistance of the left wall panel assembly 16 and the right wall panel assembly 17. The air duct 11 is arranged in the left wall panel assembly 16 and the right wall panel assembly 17. The reinforcement assembly 19 is provided with a fire-resistant component.

[0054] The air duct 11 in the embodiment of the present application is located inside the left wall panel assembly 16 and the right wall panel assembly 17, the air outlet 12 is arranged on the side opposite to the left wall panel assembly 16 and the right wall panel assembly 17, and the support assembly 18 is an ergonomically designed foothold for workers to load and unload materials. At the same time, anti-slip parts can be laid on the top of the bed 1 to improve the safety of people and machines, and at the same time, the rigidity of the bed 1 can be improved, thereby improving the accuracy of the bed 1.

[0055] The reinforcing component 19 can prevent deformation caused by clamping of the tooling fixture during the fine processing of the bed 1 or deformation caused during the hoisting and transportation process.

[0056] The refractory parts in the embodiment of the present application are refractory bricks, which can prevent the bed 1 from being deformed due to excessive temperature.

[0057] The air port 12 is disposed between two adjacent reinforcing components 19, and an avoidance groove 191 is disposed on the reinforcing component 19 to avoid the movable damper 13. The avoidance groove 191 can prevent the movable damper 13 from hitting the reinforcing component 19 during movement, thereby causing damage to the bed 1.

The transition portion 212 is used to connect two adjacent support portions 211 to form the support frame 21.

[0059] Since the laser power is proportional to the thickness of the cut plate, the higher the laser power, the heavier the cut plate, and the greater the impact on the workbench 2 during loading and unloading. The workbench 2 is separately arranged from the bed 1. During loading and unloading, the force on the workbench 2 is directly transmitted to the ground, and the bed 1 is not affected by the weight of the material, thereby preventing the bed 1 from being deformed due to excessive weight of the material and reducing the accuracy of the bed 1.

[0060] The workbench 2 is split into a support frame 21 and a support member 22, which can facilitate the replacement of damaged parts and reduce replacement costs. At the same time, the support frame 21 includes a plurality of support parts 211 and a plurality of transition parts 212, which can be assembled according to the size of the support member 22, thereby improving the compatibility of the support frame 21.

[0061] The transition portion 212 is provided with a connecting portion and a fixing portion, the connecting portion is provided with a position adjustment hole, the support portion 211 is provided with a connecting hole, and the fixing portion is passed through the position adjustment hole and the connecting hole to connect the transition portion 212 to the support portion 211 .

[0062] The position adjustment hole in the embodiment of the present application is a waist-shaped hole, the fixing part is a screw, and the connecting hole is a screw hole. The screw is passed through the waist-shaped hole and is threadedly connected to the screw hole. The head of the screw abuts against the edge of the waist-shaped hole to fix the transition part 212. The waist-shaped hole can fine-tune the position of the transition part 212 to prevent the transition part 212 from being misaligned with the support part 211 in the length direction.

[0063] See also Fig. 9 The workbench 2 also includes a support column 23, which is arranged below the support portion 211 to support the support frame 21. The support column 23 includes a column 231, an extension member 232 and at least two feet 233. The two ends of the column 231 are respectively connected to the support portion 211 and the extension member 232, one of the feet 233 is installed on the extension member 232, and the other of the feet 233 is installed at one end of the column 231 close to the extension member 232.

[0064] In the embodiment of the present application, at least two feet 233 are provided to improve the stability of the support column 23, thereby improving the stability of the workbench 2. The feet 233 are installed on the column 231 and the extension 232 of the support column 23 by threaded connection, which can facilitate the disassembly, assembly and replacement of the feet 233, and the horizontality and height of the support frame 21 can be adjusted by the feet 233.

[0065] See also Fig.10 The support member 22 includes an outer frame 221, a card plate 222 and a plurality of support bars 223. The card plate 222 is installed on the outer frame 221.

[0066] The outer frame 221 in the embodiment of the present application adopts a plate-like structure. Compared with the square tube in the prior art, the weight and consumables of the plate-like structure are relatively small, and the card plate 222 is fixed to the outer frame 221 by welding. Since the support bar 223 and the card plate 222 are both consumable parts, under the condition that the outer frame 221 adopts a low-cost plate-like structure, if the support bar 223 or the card plate 222 is damaged, the entire support member 22 can be directly replaced, which reduces the difficulty of replacement.

[0067] Lifting ears may be provided on the outer frame 221 to facilitate lifting.

[0068] When transporting a plurality of support members 22 , the support members 22 may be stacked, and adjacent support members 22 may be separated by pads, and then the plurality of support members 22 may be packed and fixed by fixing members, so that the support members 22 are easy to transport.
