Axle hole, it is characterized in that, the wheel shaft protrudes from the wheel hub and forms the shaft shoulder, and the shaft shoulder and wheel shaft are respectively provided with a gradient, institute
Stating compacting tool set includes former, pressing core rod, upper die and lower die, the middle formation of the former, pressing core rod, upper die and lower die
Belt wheel die cavity, the upper mould include outside upper mould and interior upper mould, and the interior upper mould coordinates on the pressing core rod, the outside upper mould
Coordinate it is described it is interior on mould；The lower mould include outer lower mould, in lower mould and interior lower mould, the interior lower mould coordinates in the compacting
On plug, lower mould coordinates on the interior lower mould in described, and the outer lower mould coordinates in described on lower mould, in described lower mould and
The inclined-plane that the end set of outer lower mould is engaged with the gradient of the shaft shoulder and wheel shaft.
Further, the pressing core rod passes through interior upper mould and interior lower mould, the inwall of the outer wall of pressing core rod and interior upper mould, interior
The inwall of lower mould is in close contact, and the outer wall of former inwall and outer lower mould is in close contact, the outer wall of the inwall of outer lower mould lower mould with
Be in close contact, in the inwall of lower mould be in close contact with the outer wall of interior lower mould.
The beneficial effects of the utility model are：
（1）Compacting tool set uses upper two times three structures, and direct pressing goes out the multi-step parts with labyrinth；
（2）Properties of product improve, and process control is more stable；
（3）Pressed compact loss of weight is effectively realized, reduces the waste in resource consumption and road sequence；
（4）Follow-up Vehicle Processing and deburring operation are removed, shortens logistics, advantageous product quality control.
