The utility model discloses can overcome asymmetric integral key shaft when extrusion the material flow the asymmetric extrusion force that leads to of inhomogeneous, deflection and inhomogeneous and cause the difficult problem that the part is crooked, ensured the precision of long and thin integral key shaft.
Description
Technical field
The utility model relates to a kind of asymmetric splined shaft cold extrusion equipment.
Background technology
Under the promotion of energy-saving and emission-reduction main trend, original automobile hydraulic steering (3% energy consumption) becomes inexorable trend to electric powered steering (0% energy consumption) development.Electric power steering system of automobile has a core part intermediate steering shaft, wherein a kind of is elongated solid shafting, the two ends of axle are asymmetric spline, because the rigidity of elongated asymmetric splined shaft is poor, vibration can be produced man-hour and affect the precision of part adding, so this asymmetric splined shaft is cannot be mach, process the difficult problem that asymmetric splined shaft is machinery industry.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of asymmetric splined shaft cold extrusion equipment, can overcoming that asymmetric splined shaft uneven, deflection of material flowing when extruding is asymmetric to be caused extruding force uneven and cause the difficult problem of spares bend, ensure that the precision of elongated splines axle.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of asymmetric splined shaft cold extrusion equipment is provided, comprise extruding patrix and extruding counterdie, the top of described extruding patrix is provided with the padded seat of patrix, the below of described extruding counterdie is provided with the padded seat of counterdie, on the upper workbench that the padded seat of described patrix and the padded seat of described counterdie are fixedly installed in hydraulic press respectively and lower workbench; Open locating piece is also provided with between described extruding patrix and described extruding counterdie.
In the utility model preferred embodiment, described locating piece is circular arc, the shape of the intermediate shape mating parts of described locating piece.
In the utility model preferred embodiment, described extruding patrix offers two extruding patrix locating holes, described extruding counterdie offers two extruding counterdie locating holes, described locating piece offers locating piece locating hole, and described extruding counterdie locating hole coordinates through with described locating piece locating hole.
In the utility model preferred embodiment, in the padded seat of described patrix, be provided with drift.
In the utility model preferred embodiment, under the padded seat of described counterdie, ejector beam is installed.
In the utility model preferred embodiment, the shaft length of the stroke that described extruding patrix extrudes downwards and part matches.
The beneficial effects of the utility model are: the utility model asymmetric spline cold extrusion equipment, be made up of hydraulic press and mould, mould includes extruding patrix and extruding counterdie, and between extruding patrix and extruding counterdie, be provided with open locating piece, ensure that the elongated disposable extruding of asymmetric splined shaft completes, substantially increase the coaxial precision of part, provide conveniently to the processing of next procedure, improve the quality of finished product, and save the raw material of processing, decrease machine cut number of times, save the time of Liao Hou road processing, save processing cost.
