Use full hollow half axle, therefore processing method from the full hollow half axle of suitable automobile is beneficial to the raising of automobile production rate.
The current domestic automobile preferred moulding technique of semiaxis is machine-shaping of swaging, will a mandrel pass through hollow pipe embryo material,
Then swager tup applies radially to forge, and hollow pipe embryo material realizes automobile hollow semiaxis under the collective effect of mandrel and tup
Finish forge shaping.A kind of reducer pipe forming method of announcement board in Chinese patent literature, its application publication number is CN103008514A,
Swaged shaping hollow half axle using single rod and precise forging machine tup precision.This method is in process due to the length of mandrel
More long, the structure into cantilever beam causes workpiece bounce property big under external force, makes production noise big, forging process precision drop
It is low.
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is：How to provide a kind of suitable
Precision for the larger hollow half axle of draw ratio is swaged processing, is conducive to reducing the bounce of workpiece when processing, and reduces processing
Noise, improves the mandrel swaged for automobile hollow semiaxis precision of machining accuracy.
In order to solve the above-mentioned technical problem, the utility model employs following technical scheme：
A kind of mandrel swaged for automobile hollow semiaxis precision, including the cavity shape phase one with hollow half axle to be processed
The axis body of cause, it is characterised in that the axis body includes removably being co-axially mounted the first mandrel and the second mandrel together, institute
State one end that the first mandrel and the second mandrel mutually deviate from and be to be engaged for the clamping device with rotary forging press and grip
Bare terminal end, and the junction of the two equal diameters.
Using said structure, the clamping of side where being separately fixed at the bare terminal end of the first mandrel and the second mandrel is filled
Put, is engaged by the first mandrel and the second mandrel and hollow half axle is carried out precision and swage processing so that hollow half axle is in rotation
Remain that two ends support in forging process, so as to avoid the formation of cantilever beam force structure, be conducive to reducing the jump of workpiece when processing
Dynamic property, reduces processing noise, improves machining accuracy.
As optimization, on the end face of first mandrel have boss, on the end face of second mandrel have with it is described
The groove that boss matches, the boss of first mandrel is inserted into the groove of second mandrel.
Using said structure, the first mandrel and the second mandrel can be made to form grafting and to be coordinated, improve the stabilization of the two connection
Property.
Used as optimization, the boss is conical boss, and the groove is cone-shaped blind hole.
So, by the cooperation of conical boss and cone-shaped blind hole, the two can be made preferably to be protected when coordinating
Coaxial cooperation is held, is conducive to improving the machining accuracy of hollow half axle.
As optimization, the height of the depth more than the boss of the groove.
In this way it can be ensured that boss can be fully mated into groove, so that the end face of the first mandrel and the second mandrel
Can fit, it is to avoid there is gap on the periphery of junction, be conducive to improving the precision of swaging of hollow half axle.
Used as optimization, the periphery of the junction of first mandrel and the second mandrel matches somebody with somebody what work was processed again after using assembling
Mode is made.
In this manner it is ensured that the machining accuracy and axiality of the periphery of the junction of the two, and then improve hollow half axle
Processing stability and machining accuracy.
Used as optimization, the junction of first mandrel and the second mandrel is located in the minimum diameter of axis body section.
Using above-mentioned setting, it is possible to use this mandrel processing two ends aperture is larger, and the less hollow half axle of median pore radius is carried
The scope of application of mandrel high.
In sum, there is the utility model the precision suitable for the larger hollow half axle of draw ratio to swage processing, favorably
The advantages of bounce of workpiece when processing is reduced, reduction processing noise, raising machining accuracy.
Brief description of the drawings
Fig. 1 is the structural representation of hollow half axle to be processed.
Fig. 2 is the structural representation of the utility model embodiment.
Fig. 3 is the structural representation of the first mandrel in Fig. 2.
Fig. 4 is the structural representation of the second mandrel in Fig. 2.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
During specific implementation：As shown in Figure 1 to 4, a kind of mandrel swaged for automobile hollow semiaxis precision, including with treat
The consistent axis body of the cavity shape of hollow half axle is processed, the axis body includes removably being co-axially mounted the first core together
The mandrel 2 of axle 1 and second, one end that the mandrel 2 of first mandrel 1 and second mutually deviates from is for the clamping with rotary forging press
Device is engaged the bare terminal end for gripping, and the junction of the two equal diameters.
Using said structure, the clamping of side where being separately fixed at the bare terminal end of the first mandrel and the second mandrel is filled
Put, is engaged by the first mandrel and the second mandrel and hollow half axle is carried out precision and swage processing so that hollow half axle is in rotation
Remain that two ends support in forging process, so as to avoid the formation of cantilever beam force structure, be conducive to reducing the jump of workpiece when processing
Dynamic property, reduces processing noise, improves machining accuracy.
