Abstract
The invention discloses a device and method for laser electrochemical composite drilling of an inclined magnetic cathode plate, belonging to the field of laser processing in special processing, including a laser processing system, an electrochemical processing system and a control system; in order to solve the problem of laser drilling in laser drilling To solve the problems of large taper and low efficiency, the device of the present invention uses the electric field generated by the air-end magnet and the material to accelerate the flow of molten metal, thereby improving the drilling efficiency, and at the same time, uses the magnetic field to restrict the plasma from top to bottom to reduce the aperture. The electrochemical reaction further expands the aperture and reduces the taper; compared with the ordinary drilling method, the laser electrochemical composite drilling of the inclined magnetic cathode plate proposed by this method can gradually reverse the taper of the hole and further improve the taper of the hole And improve drilling efficiency. The method makes full use of the constraint of the magnetic field on the plasma. Compared with the existing method, the invention has simple device, convenient operation and high efficiency, and can significantly improve the aperture taper and drilling efficiency.
Description
technical field [0001] The invention belongs to the field of laser processing in special processing, and relates to a device and method for laser electrochemical composite drilling of an inclined magnetic cathode plate, which is suitable for through-hole processing of metal materials. Background technique [0002] Laser drilling has the characteristics of fast drilling speed, high efficiency, large depth-to-diameter ratio, non-contact processing, and no tool wear, which makes the application field of laser drilling gradually wider. But at the same time, laser processing will inevitably bring some defects, such as recast layers, microcracks, tapered holes, etc. [0003] When using laser drilling technology to process the through holes of the above components, taper and depth-to-diameter ratio are important indicators for measuring holes. The larger the taper, the poorer the quality of the processed hole, and the larger the depth-to-diameter ratio, the more difficult it is to ...
