Power, the inherent quality of product is improved, extend service life of product etc. and all have and be of great significance.Heat treatment not only needs
Consider Design of Heat Treatment Process, also to take into full account that heat treatment tooling designs.The heat treatment tooling design of science, can be that workpiece exists
Shove charge, unload stove, especially provided when quenching lifting when cooling down, hanging, placement and cooling it is a kind of safe, easily, steadily
Heat treatment condition.Heat treatment efficiency can be improved, labor strength is reduced, especially can effectively control the cooling of workpiece to become
Shape, the artificial preparation carried out before the online lifting of high temperature is avoided, reduces security risk.
The content of the invention
The purpose of this utility model is to be directed to above-mentioned present situation, there is provided it is a kind of it is safe, easily, smoothly lifting, hanging
Particularly quench the heat treatment condition of cooling.Heat treatment efficiency can be improved, labor strength is reduced, especially can effectively control
The cooling strain of single flange main shaft, the artificial preparation carried out before the online lifting of high temperature is avoided, reduces security risk.
The implementation method of the utility model purpose is a kind of quenching hook frock for the heat treatment lifting of single flange main shaft,
Hanger is arranged at shoulder pole top, and intermediate symmetry is disposed with two connecting holes, and two annular quenching chain two ends are fixed on suspension ring, suspension ring
It is separately fixed on two connecting holes；Two annular quenching chains are enclosed on the recess at the crossbeam both ends of quenching hook；
The quenching hook is followed successively by vertical section, oblique straight section and arc section from top to bottom；Arc section diameter D and major axis diameter d
Relation be：D-d≥20mm；The downward extended line a of vertical section passes through the center of circle in the center of circle of arc section, arc section hook and arc section
Line c and the downward extended line a of vertical section between angle be 120 °；The line in the center of circle of arc section hook and arc section
Angle between c and oblique straight section 12 and the line b of arc section joining is 165 °.
The utility model designs according to the contour structures feature according to single flange main shaft.
, will using the quenching chain of two same sizes before single flange main shaft enters furnace treatment reason using the utility model
Quenching shoulder pole is connected with quenching hook, hooks quenching shoulder pole hanger by travelling crane hook, then quenching hook is hooked into single flange main shaft and leaned on
The shaft at nearly center of gravity position, start driving and carry out shove charge, and carry out quenching cooling using same procedure and unload stove.Using this reality
With new, can for single flange main shaft shove charge, unload stove, especially quenching lifting when cooling down, hanging, placement and cooling when provide
It is a kind of it is safe, easily, stable heat treatment condition.
The utility model can improve heat treatment efficiency, reduce labor strength, especially can effectively control single flange master
The cooling strain of axle, the artificial preparation carried out before the online lifting of high temperature is avoided, reduces security risk.

Embodiment
The utility model is described in detail with reference to the accompanying drawings.
Hanger 5 is arranged at reference picture 1,2, the top of shoulder pole 1, and intermediate symmetry is disposed with two connecting holes 6, two annular quenching chains 2
Two ends are fixed on suspension ring 7, and suspension ring are separately fixed on two connecting holes 6；Two annular quenching chains are enclosed on the horizontal stroke of quenching hook 3
The recess 9 at the both ends of beam 8.
Reference picture 3a, b, quenching hook 3 are followed successively by vertical section 11, oblique straight section 12 and arc section 13 from top to bottom；Arc section is straight
Footpath D and major axis diameter d relation is：D-d≥20mm；The downward extended line a of vertical section passes through the center of circle of arc section, arc section hook
With the line c and vertical section in the center of circle of arc section between downward extended line a between angle be 120 °；Arc section hook and circular arc
Angle between the line c and oblique straight section 12 and the line b of arc section joining in the center of circle of section is 165 °.
Vertical section 11, oblique straight section 12 and the arc section 13 of quenching hook 3 have strengthening rib strip 10, to strengthen quenching the carrying of hook
Power.
Reference picture 1,4, using the utility model, the hanger 5 of quenching shoulder pole 1 is hooked with the hook of driving, starts driving, will
Quenching hook 3 hooks single flange main shaft shaft 15 close to flange 14, starts driving, single flange main shaft is hung in the platform left
The enterprising luggage stove of car stove, driving is started after installing and removes the utility model, car type furnace is driven into fire door is shut in burner hearth, to list
Flange main shaft carries out Quench heating.After the completion of Quench heating, fire door is opened, outputs table, hook will be quenched according to original by starting driving
Lift hook position hooks single flange main shaft shaft, is hung in cooling bath and cools down.After the completion of quenching cooling, single flange main shaft is hung again
To table shove charge, performance temper is carried out.After performance temper, fire door is opened, table is outputed, is air-cooled to certain temperature
Afterwards, driving is started to hook single flange main shaft shaft according to the mark performed and be hung to next procedure quenching hook.
Using the utility model be heat-treated hoisting fixture, make single flange main shaft shove charge, unload stove, especially quench cool down when
Lifting, hanging, placement and cooling when provide it is a kind of it is safe, easily, stable heat treatment condition.Heat treatment effect can be improved
Rate, labor strength is reduced, especially can effectively control the cooling strain of single flange main shaft, avoid manually carrying out high temperature online
Preparation before lifting, reduce security risk.
Heat treatment lifting of the utility model to single flange main shaft has versatility.
