Abstract

The invention relates to laser wire-filling local bionic-texture manufacturing method and equipment for metal functional surfaces, belongs to the field of processing of metal materials and aims to provide a technical method and a manufacturing device which are capable of effectively improving thermal fatigue resistance and wear resistance on the metal functional surfaces. For different metal base materials, by combining the automatic wire filling technology with the vision sensing and small-power laser technology, a novel method for manufacturing bionic texture on metal functional spatial curved surfaces is provided. In order to implement the mentioned technical method, strengthening equipment composed of a control unit, a vision system, an adjustable temperature heating wire feeding machine, a laser and a five-freedom-degree numerical-control worktable is researched, thermal fatigue resistance and wear resistance of the metal functional surfaces are effectively improved, cost performance is good and production efficiency is high.

Description

technical field [0001] The invention belongs to the field of metal material processing. Background technique [0002] The bionic strengthening technology of metal functional surface starts from the perspective of bionics. Through the study of wear-resistant biological prototypes and anti-fatigue biological prototypes, the anti-wear and fatigue-resistant structures of biological prototypes are "replicated" on the functional surface, and the bionic strengthening is carried out by laser. The functional surfaces of mold products, lathe guide rails, valves, and rolls form a bionic structure that is resistant to wear and fatigue, thereby improving the life of molds, lathe guide rails, valves, and rolls. [0003] [b1] Taking typical metal workpiece molds as an example, although my country's mold production has developed rapidly, there is still a big gap compared with foreign advanced levels, mainly in the aspects of long manufacturing cycle, low manufacturing precision, and short m...
