Description
Technical field
The utility model relates to a kind of mould applications, particularly relates to a kind of asymmetric spline continuous 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, and the feature of this part is the two ends of axle is asymmetric spline, process the difficult problem that asymmetric splined shaft is machinery industry, and asymmetric spline is cannot be mach.In prior art after process, needing the part of completion of processing to take out, then put into new hair training, consume man-hour during this, efficiency comparison is low, also compares and wastes energy.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of asymmetric spline continuous cold extrusion equipment, can realize carrying out continuous cold extrusion process to multiple part, significantly improve production efficiency.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of asymmetric spline continuous cold extrusion equipment, comprise: hydraulic press, push rod and mould, described mould is arranged on the lower workbench of hydraulic press, described push rod is arranged on the upper workbench of hydraulic press, described mould comprises: guide die and extrusion die, described guide die is arranged on the top of described extrusion die, the guiding die cavity matched with part is provided with in described guide die, the extrusion die cavity matched with spline-shaped to be processed is provided with in described extrusion die, the axle center of described guiding die cavity and described extrusion die cavity is in same straight line.
In the utility model preferred embodiment, the bottom of described guiding die cavity is provided with stop collar.
In the utility model preferred embodiment, the diameter of bore of described stop collar is equal with the maximum gauge in described extrusion die cavity.
In the utility model preferred embodiment, described guide die offers multiple upper locating hole, described extrusion die offers multiple lower locating hole, described upper locating hole is connected with described lower locating hole is penetrating, penetrate described upper locating hole and described lower locating hole by alignment pin, described guide die is fixedly connected with described extrusion die.
In the utility model preferred embodiment, the stroke of upper workbench and the processing length of part of described hydraulic press match.
The beneficial effects of the utility model are: the utility model is by hydraulic press executable operations, and part is carried out disposable extruded in same mould, save a large amount of raw material, after a part extruding terminates, directly can put into new parts in guide die simultaneously, a upper part is extruded extrusion die by new parts in extrusion process, thus realize continuously extruded, significantly improve production efficiency.
Accompanying drawing explanation
