The invention discloses a pattern float
valve guide edge micro-curvature
stamping die wear inhibition method, and relates to the technical field of
stamping die manufacturing, and the method comprises the following steps: constructing a controllable wear profile based on a
crystal orientation gradient, and controlling the tip of an edge to be lt through
directional solidification; 111gt, 111gt; a
crystal face, the base of which is lt; 001gt, 001gt; a
crystal face forms a differential wear rate; according to the method, controllable abrasion of the edges and
active compensation of forming deviation are achieved through
crystal orientation gradient design, a traditional
coating is replaced with matrix orientation abrasion, and the problems of poor
coating uniformity and peeling off are solved; contact stress is dissipated by means of the nano twin crystal layer, a low-stress abrasion cycle is formed, and the material
utilization rate is increased; programmable regulation and control of a wear profile are realized through an inverse parabola model, and the precision
bottleneck of a traditional model is broken through; the
surface energy gradient is used for driving the lubricating liquid to directionally migrate, and a high-speed
stamping lubricating blind area is eliminated; the integrated piezoelectric-SMA composite support compensates abrasion deformation in real time, and the material guiding deviation is eliminated in combination with an intelligent
model switching strategy.
