The present application relates to the technical field of
woodworking machinery equipment manufacturing, and discloses a novel preparation method of a pressing wheel for large automatic
woodworking machinery, which adopts 45 steel
round bar material, and after blanking, the material is subjected to preliminary mechanical
processing to obtain a primary workpiece, the obtained primary workpiece is placed into an
atmosphere protection heat treatment furnace for preliminary heat treatment, the primary workpiece after the preliminary heat treatment is processed by using a high-precision
machine tool, the inner hole is preliminarily enlarged for finish
machining, a margin is reserved for the inner hole of the primary workpiece, a secondary workpiece is obtained after
processing, then the secondary workpiece is directly placed into a gas
carburizing furnace, and the pressing wheel is obtained after
processing, the pressing wheel is cooled in air after being discharged from the furnace, the pressing wheel is placed into a sealed furnace,
nitrogen,
ammonia and a beautifying agent are introduced, and heating is performed, and the pressing wheel is cooled in air after processing. The present application has no three waste emissions, is green and
environmentally friendly, easy to operate, low in cost, and far higher in surface
hardness,
wear resistance and
corrosion resistance than the technical index requirements.
