Description

Technical Field

[0001] The invention relates to the technical field of aluminum plate processing, and specifically discloses a local thermal cutting device and a thermal cutting method for aluminum plate processing. Background Art

[0002] Thermal cutting refers to a method of cutting and separating metals using high temperatures. Common thermal cutting methods include gas cutting, plasma cutting, and laser cutting. The three-dimensional five-axis fiber laser cutting machine is a high-end machine tool cutting equipment that integrates light, machinery, electricity, and gas. It is a commonly used machine equipment in the thermal cutting process of aluminum plates. It can cut parts of aluminum plates at different angles and directions to achieve more complex cutting tasks. Secondly, it has a five-axis control system, which means it can perform motion control in five degrees of freedom, thereby achieving more precise and flexible cutting operations.

[0003] After searching, the patent with announcement number CN116967631B discloses a local thermal cutting device for processing spare parts, which relates to the field of thermal cutting technology and includes a chimeric component. The local thermal cutting device for processing spare parts, through the design of the chimeric component, is equipped with a mechanical component inside the chimeric component, and the mechanical component is fixed by the chimeric component. At the same time, the chimeric component cooperates with the mechanical component to move, and the mechanical component can be driven by moving the chimeric component. The mechanical component can fix the spare parts, which is convenient for the subsequent cutting process. At the same time, the rotating block can tighten the connecting rod, one end of the connecting rod is connected to the rotating block, and the other end is connected to the mechanical clamp. The mechanical clamp can be retracted by rotating the rotating block, so that the mechanical clamp can be adjusted according to the size of the spare parts on the basis of the original fixation, and the workbench component and the cutting component are cooperated for cutting. The workbench component can collect the debris in the cutting process, keep the working environment clean, and ensure the safety of cutting.

[0004] Based on the above search and in combination with the prior art, it is found that when the existing local thermal cutting equipment is cutting the aluminum plate, the aluminum plate material and the cut material after cutting are still on the entire cutting equipment.

[0028] 2.

The laser cutting head can be cooled and protected by water circulation, and waste water can pass through the support mesh platform and the inclined mesh plate and fall into the water tank for recycling.

[0060] In summary, the working principle of the present invention is as follows: when in use, the user opens the box door 8, places the aluminum plate on the supporting mesh table 21, drives the second threaded rod 2004 to rotate through the second forward and reverse motor 2003 in the clamping and positioning assembly 20, lowers the height of the clamping frame 2002 on the second threaded rod 2004 and in the center groove 2001, so that the rubber seat 2005 is pressed on the aluminum plate to fix the aluminum plate, and then, the first forward and reverse motor 26 in the feeding and discharging assembly is used to drive the driving shaft 27 and the first threaded rod 35 to rotate, so that the moving sleeve 31 moves on the first threaded rod 35 and the guide rod 25, and the feeding is moved. The table 12, the support net table 21 and the aluminum plate are moved to the cutting position in the case 1, and then the case door 8 is closed. Next, the user controls the three-dimensional five-axis gantry fuselage structure 9 to work through the control cabinet 6, and can drive the laser cutter 10 to perform motion control in five degrees of freedom through the five-axis control system, adjust the laser cutter 10 to the cutting position, so that the laser cutting head on the laser cutter 10 corresponds to the cutting matching groove 24, and synchronously drives the annular frame 1104 and the water spray pipe 1105 in the water spray assembly 11 to move, and uses the three-dimensional five-axis gantry fuselage structure 9 to drive the laser cutter 10 to move to implement local heat treatment of the aluminum plate. During the cutting process, the water in the water tank 3 is extracted and sprayed at the cutting position by the water pump 1101 in the water spray assembly 11, and the laser cutting head is cooled by water circulation, and the waste water passes through the support mesh table 21 and the inclined mesh plate 18 and falls into the water tank 3 for recycling. The molten material is blown away by the high-speed water flow to achieve the chip prevention function. During cutting, the user also ventilates and dissipates the interior of the entire chassis 1 through the cooling fan 7 to ensure that the equipment inside the chassis 1 operates normally. After the cutting is completed, the user turns off the water pump 1101, the cooling fan 7, the laser cutter 10 and the three-dimensional five-axis cutting machine 10. The shaft gantry body structure 9 opens the box door 8, and the reverse action of the first forward and reverse motor 26 in the material inlet and outlet assembly drives the movable sleeve 31, the feeding table 12, the supporting mesh table 21 and the aluminum plate material and the cut material to move in the opposite direction, so that the aluminum plate material and the cut material are gradually moved out of the chassis 1, and the pulley 36 slides on the lifting frame 23 and forms a lifting phenomenon. When the pulley 36 gradually moves to the highest position, the telescopic plate 33, the movable frame 32 and the ejecting wheel 28 will be lifted up, thereby changing the inclination of the cut material under the lifting action of the ejecting wheel 28, so that the cut material slides onto the inclined mesh plate 18 and is moved to the waste collection box 5 for collection.

[0061] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
