Kerosene passes through, and truck drive shaft product is a more important part, and power transmission shaft will bear high-speed friction in.In order to prolong
The service life of long power transmission shaft, generally requires and carries out Q-tempering processing to drive shaft parts surface, handled by Q-tempering
To improve the surface strength and wearability of power transmission shaft.
At present, interior star-wheel drawing process is that interior star-wheel to be quenched is placed on the transmission net band of tempering furnace one by one, is passed
Send guipure that interior star-wheel to be quenched is delivered into tempering furnace and carry out Q-tempering processing, interior star-wheel is completed after Q-tempering processing, passed
Send guipure that the interior star-wheel for having completed Q-tempering processing is delivered into its discharge end, then take interior star-wheel away.It is disadvantageous in that
The side of interior star-wheel is contacted with transmission mesh bag all the time, and the carburizing atmosphere and quenching oil of heart wheel surface are uneven, occur quenching not
Completely situations such as.
A kind of carburizing atmosphere is designed for this and quenching oil appropriate can pass through, and clamps the heart wheel of interior star-wheel uniform quenching
Utensil is just necessary, it is desirable to be able to ensure that there is certain carburized layer depth at spline position and the hardness number in given size expires
Sufficient product technology requirement.
Utility model content
The weak interior star-wheel quenching caused of holding capability that the utility model will solve existing interior star-wheel quenching fixture is uneven
Even deficiency can make interior star-wheel quenching and carburizing uniform there is provided a kind of interior star-wheel loading rod.
In order to achieve the above object, the utility model uses following technical scheme.
A kind of interior star-wheel loading rod, including backing disk and conveying bar, the cross section of conveying bar is cross, backing disk
It is provided with and is arranged through hole with the criss-cross of conveying bar cooperation, backing disk is set in outside conveying bar；Backing disc centre line with
Conveying rod axis are overlapped, and the surrounding on backing disk with respect to conveying bar is uniformly provided with steam vent.
Interior star-wheel is set on conveying bar, carburizing atmosphere and quenching oil are by steam vent, and the cross section of conveying bar is ten
Font, the contact area with interior star-wheel is few, and the vent structure of backing disk reduces the through-rate of carburizing gas, so as to ensure
Carburizing atmosphere and quenching oil it is uniform, it is ensured that there is certain carburized layer depth at spline position and the hardness number in given size is met
Product technology requirement.
Preferably, conveying bar is the heat-resisting steel disc of butt welding shaping after two panels bending.Moulding process is simple, rigidity after shaping
There is no gap after height, soldering, be conducive to the shunting of carburizing atmosphere and quenching oil, make the carburizing thickness of interior star-wheel uniform.
Preferably, the front end of conveying bar is provided with wedge angle.Star-wheel is arranged into conveying bar in convenient, while being conducive to carburetted gas
The entrance of atmosphere, while what the wedge angle of front end was conducive to the wiping to conveying bar conveniently to be produced to conveying bar in carburizing process
The cleaning of the debris of chip.
Preferably, backing disk is provided with transition chamfering towards the side of conveying bar front end.Be conducive to backing disk with it is interior
The inner ring of star-wheel coordinates.
Preferably, conveying bar is turned round around its axis turn 90 degrees 180 degree.Carburizing gas is set to be turned near conveying bar
Dynamic mixing, makes the carburized layer thickness of interior star-wheel uniform.
Preferably, the size of conveying bar, which is the size for being arranged through hole, subtracts 1 to 3 millimeters.Facilitate backing disk in conveying
Movement on bar.
It is of the present utility model to be beneficial in that：Interior star-wheel uniform quenching can be made, carburizing atmosphere and quenching oil pass through row
Stomata, the cross section of conveying bar is cross, and the contact area with interior star-wheel is few, the vent structure reduction carburizing of backing disk
The through-rate of gas, so as to ensure the uniform of carburizing atmosphere and quenching oil, it is ensured that spline position have certain carburized layer depth and
Hardness number in given size meets product technology requirement.
