This is widely used.Automobile making has a lot of carburizing steel and quenched and tempered steel parts, fine to it
Dimension direction, endurance, light weight and the size aspect such as accurately proposes requirements at the higher level, and Cold forging
Ratio shared in the parts manufacturing industry of automobile constantly increases.
Along with car, the development of Light-duty Vehicle, the range of spline is continuously increased, particularly mould
Number is involute spline and the rectangular spline of about 1mm, the most substantially uses cold-forge forming technique,
As rub with the hands crowded, just squeeze, edging etc..Domestic the most also it is dependent on machine tooling, with this processing method ratio
Relatively, Cold forging saves material than machining and other method, it is also possible to machining shape expeditiously
More complicated part, its size and shape precision is higher, and surface quality is good.
Utility model content
This utility model mainly solves the above-mentioned technical problem existing for prior art, it is provided that one
Plant precision forging internal splined worm.This mao of stock improves the precision of internal spline, and joining when using
Right.
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals:
A kind of precision forging internal splined worm, including: worm screw body, one end of described worm screw body sets
It is equipped with the keyhole that machining is made, in described keyhole, is provided with the spline that cold forging punch process is made；
Described worm screw body includes the first trunk portion, the second trunk portion, and described second trunk portion diameter is big
In described first trunk portion, one end of described second trunk portion is connected with described first trunk portion, another
Hold and be connected by reducer and the 4th trunk portion, in described 4th trunk portion, keyhole is set.
Optimize, above-mentioned a kind of precision forging internal splined worm, described 4th trunk portion and reducer
Between be provided with back-up ring.
Optimize, above-mentioned a kind of precision forging internal splined worm, described second trunk portion is provided with
