Meshing cover hollow tube mold processing

The utility model discloses a meshing cover hollow tube mold processing, including pre forging die and finish forge mould, pre forging die includes mould and dummying reaming lower mould in the dummying reaming, and the circular recess unanimous with the blank diameter is seted up including being used for underreamed radius platform to the mould in the dummying reaming on the dummying reaming lower mould, the finish forge mould includes mould on the finish forge tooth, finish forge tooth lower mould and precision forging die fore -set, and mould and finish forge tooth lower mould closure state form down on the finish forge tooth, and to forge the chamber the same with the profile of tooth of meshing cover hollow tube, and the precision forging die fore -set is used for supporting the blank after the reaming. Use the utility model provides a meshing cover hollow tube mold processing, castellated bending strength, contact fatigue strength and anti -impact are high, the superior performance, castellated wearability is good, and the meshing stationarity is high. It is few to forge the follow -up hole allowance of back blank, practices thrift the hole material, has improved production efficiency and material utilization rate.
