Specific embodiment
By the following examples can detailed explanation the utility model, open the purpose of this utility model is intended to protect
All technological improvements in the scope of the utility model.
The large-scale hot rolling memorial archway in conjunction with described in attached drawing 1-2 depresses hole machined tooling, including panel 1, flange 13 and sleeve 5,
Stepped hole 14 is equipped between the two sides of panel 1, screw of the flange 13 in outer edge screw hole B11 is fixed on panel
In screw hole 15 on 1, the necking segment B12 of 13 one end of flange is mounted in stepped hole 14, and the end of 13 other end of flange is equipped with contracting
Cervical part of esophagus A4, and the cone section of transition connection is equipped between necking segment A4 and the end face of flange 13, one end of sleeve 5 is socketed in necking segment
The outside of A4, and be welded to connect between the end face of sleeve 5 and the outside for boring section, in the stepped hole inside the other end of sleeve 5
