Description

Technical Field

[0001] The utility model belongs to the technical field of laser drilling, in particular to a limiting device for laser drilling of copper, steel and aluminum tubes. Background Art

[0002] Traditional punching is commonly used to create holes in copper, steel, and aluminum tubes for hardware accessories. Punching involves shearing, punching, and bending the tubes through plastic deformation of a die. This method is suitable for high-volume production and offers low costs. The advantages of punching are high efficiency, precision, and repeatability. However, its disadvantages are that it is not suitable for unusual or complex hole shapes. Laser drilling is now also being used for some hardware copper, steel, and aluminum tube punching processes.

[0003] The laser drilling process is a thermophysical interaction between laser light and material, determined by the laser beam characteristics (including wavelength, pulse width, beam divergence, and focusing state) and the various thermophysical properties of the material. Existing laser drilling machines often require a clamping mechanism to position the product for easy drilling when drilling holes in plastic or metal sheets.

[0004] However, existing laser drilling is mostly carried out on a workbench. The copper, steel, and aluminum tubes of hardware accessories are placed on the workbench (below the laser emission port), and then the laser is emitted by the laser to perform drilling. Since the copper, steel, and aluminum tubes of hardware accessories are circular in structure, they are prone to rolling during the drilling process, resulting in unqualified drilling.
