Further, being provided with lateral clearance between described gradient boss and slope groove, several piece pad is respectively embedded into aforementioned
In lateral clearance.
Further, the both sides that helical axis compression section is perpendicular to gradient boss or slope groove are respectively equipped with square
Notch, the vertical edges of described square notch vertically puts in helical axis compression section, and it is embedded with and feeds leading portion material with helical axis
Close scotch；Described scotch outer end is by the horizontal sides of square notch with helical axis charging leading portion weldering even.
Further, the hardness of described helical axis charging leading portion is HB200～240, and the hardness of helical axis compression section is
HRc50～55.
This utility patent has the advantages that
Feed screw shaft is divided into helical axis charging leading portion and the spiral of two kinds of different steel grade different hardness by this utility model
Axial compression contracting back segment, and both are integrally welded by aforementioned to use structure that boss and groove connect, simple in construction, easy to process,
Greatly reduce the production cost of feed screw shaft.After feed screw shaft abrasion, only need to remove the helical axis compression of serious wear
Back segment, again welds new helical axis compression back segment, is not required to change whole feed screw shaft, extends feed screw shaft
Working life, reduces maintenance cost, shortens maintenance cycle, improves work efficiency.
Advantage of the present utility model and feature, conciliate carrying out diagram by the non-limitative illustration of preferred embodiment below
