The invention discloses laser additive and subtractive composite manufacturing equipment for large mold maintaining and manufacturing, and belongs to the technical field of laser additive and subtractive equipment. The equipment overall adopts a gantry framework type structure, movable modularization packaging is conducted on a workbench surface and auxiliary equipment, a vision positioning technology is introduced, and automatic searching type repairing machining in the additive and subtractive repairing process is achieved by positioning and searching a to-be-repaired area; in order to increase the Z-axis space utilization rate, full-size covering of a repaired part is achieved by adopting a second-level auxiliary moving mechanism; and high-activity metal repairing machining is achievedby adopting a flexible cover type sealing technology. The laser additive and subtractive composite manufacturing equipment for field maintenance of large structural parts has the characteristics of the open type, the large space, the high flexible intelligence and the like, has the high repairing efficiency and additive and subtractive integrated repairing capability and is low in equipment running cost and free of pollution.
Description
technical field [0001] The invention relates to the technical field of laser addition and subtraction equipment, in particular to a laser addition and subtraction composite manufacturing equipment for large-scale mold maintenance and manufacturing. Background technique [0002] Molds are the basic tools and equipment for industrial production in my country. In aerospace, shipbuilding, nuclear power, weapons and other fields, 60%-90% of product parts are produced and processed using molds. The development status of molds, especially molds with high service requirements, represents The overall development level of my country's industry. With the technological progress of the aerospace, automobile and mold industries in recent years, the structure and shape of parts have become more and more complex, and the materials have become more and more difficult to process. Therefore, traditional metal cutting methods are severely challenged. The use of laser additive manufacturing and ...
