Description

Technical Field

[0001] The present invention relates to the technical field of metal sheet processing, and particularly to a metal sheet processing device based on high-energy laser beams. Background Art

[0002] When processing a metal sheet with high-energy laser beams, a plasma welding machine is often used to utilize the plasma arc as a heat source. An arc is excited by a high-frequency oscillator to ionize argon gas to form a plasma. When the plasma passes through a fine-hole nozzle, it is compressed to form a plasma arc with highly concentrated energy. The plasma arc melts the area to be welded on the metal sheet through high temperature to form a molten pool, thereby achieving precise welding of the metal sheet.

[0003] For example, the existing application number CN202411908143.2 discloses a cutting design method and a welding method for metal profile components, including the steps of: establishing a pre-assembled model of the profile components in 3D software; designing the size and shape cutting scheme for each profile component according to the pre-assembled model; designing a matching combined structure at the joint position of the profile components; setting marks on the surface of another profile component along the edge of one profile component at the contact position of two profile components; setting coherent marks on the surface of other profile components along the edge of one profile component at the contact positions of multiple profile components; separately exporting the processing scheme of the designed profile components. This application has the characteristics of high processing efficiency and high precision, and can make the processed profile components convenient for assembly and welding.

[0004] However, during the welding of a metal sheet using a plasma welding machine, to avoid the influence of nozzle overheating or arc blow on the welding precision of the metal sheet with high-energy laser beams, it is usually necessary for the welding operator to hold the welding torch at an angle of 60° - 80° with the surface of the metal sheet according to the thickness of the metal sheet, and the nozzle is 5 - 8 mm away from the workpiece. This not only increases the operation difficulty of the welding operator, but also is extremely likely to cause the phenomenon of arc blow due to the shaking and fatigue of the arm muscles when the welding operator holds the welding torch, affecting the processing efficiency of the metal sheet with high-energy laser beams and the qualification rate of the metal sheet finished product. Summary of the Invention

[0005] In view of this, the present invention provides a metal sheet processing device based on a high-energy laser beam, which realizes the support and assistance for the welding torch, automatically maintains an angle of 60°-80° between the welding torch and the surface of the metal sheet during welding of the metal sheet, and at the same time keeps the nozzle at a distance of 5-8 mm from the metal sheet, realizing the support and assistance for the nozzle. This not only simplifies the operation difficulty of the welding operator, but also greatly avoids the phenomenon of arc blow caused by the influence of arm muscle tremors and fatigue of the welding operator when holding the welding torch, ensures that the arc energy is concentrated on the molten pool, avoids the short-circuit phenomenon caused by the contact between the nozzle and the workpiece, improves the processing efficiency of the high-energy laser beam metal sheet, as well as the working efficiency and use effect of the device in the actual application process, and further improves the qualification rate of the metal sheet finished product; In addition, when the present invention is used, according to the thickness of the metal sheet, it realizes the precise control of the support angle between the welding torch and the surface of the metal sheet, and the distance between the nozzle and the metal sheet, makes the heat input more accurate, ensures the rapid formation and solidification of the molten pool, and improves the welding quality of the metal sheet; At the same time, during the welding of the metal sheet, the area to be welded in front of the metal sheet is automatically cleaned, and the cleaning range of the area to be welded is increased, ensuring the cleaning effect of the area to be welded of the metal sheet.
