Abstract
The invention discloses a kind of finish-forging dies of automobile hub bearing flange plate outer ring, it is related to the processing mold technical field of automobile hub bearing flange plate outer ring, including upper die and lower die, the center of upper mold is equipped with upper mold core, lower die center corresponds to upper mold core equipped with lower mold core, and the end face of upper mold and the end face of lower die are plane, and the end face of upper mold and the end face of lower die fit, upper mold on the outside of upper mold core is equipped with the protrusion around upper mold core, and the position of respective protrusions is equipped with groove in lower die.The structure that the present invention is matched using protrusion with groove is forged to closed forging, and the overlap of forging is smaller, saves raw material；Protrusion and the gradient of groove are big, reduce forming energy when forging, improve the service life of mold.
Description
Technical field
The present invention relates to the processing mold technical fields of automobile hub bearing flange plate outer ring, more particularly to a kind of automobile
The finish-forging die of hub bearing flange plate outer ring.
Background technique
Hub bearing flange plate outer ring is located in the transmission system of automobile for constituting hub-bearing unit.Hub bearing
Main function is load capacity and provides accurate guidance for the rotation of wheel hub, it is desirable that it has carrying axial load and radial load
The ability of lotus.Currently, hub bearing flange plate outer ring is mainly fabricated by forging technology, forging mold is after processing is completed
There are larger overlap, raw material largely to waste for forging；And forging mold molding needs more energy, leads to die life
Shorten.
Summary of the invention
The object of the invention is that providing a kind of automobile hub bearing flange plate outer ring to solve the above-mentioned problems
Finish-forging die.
The present invention through the following technical solutions to achieve the above objectives:
A kind of finish-forging die of automobile hub bearing flange plate outer ring, including upper die and lower die, the centre bit of the upper mold
Upper mold core is installed, lower die center corresponds to upper mold core equipped with lower mold core, and the end face of the upper mold and the end face of lower die are
Plane, the end face of upper mold and the end face of lower die fit, and the upper mold on the outside of the upper mold core is equipped with the protrusion around upper mold core,
The position of respective protrusions is equipped with groove in lower die.
Preferably, the outside with upper mold end face of the protrusion are in contact position equipped with arc sections, the outside of groove and lower die
End face is in contact position equipped with arc sections.
Preferably, the cross section of the protrusion is " U "-shaped, and the cross section of groove is inShape.
The beneficial effects of the present invention are: the structure that the present invention is matched using protrusion with groove is forged to closed forging
It makes, the overlap of forging is smaller, saves raw material；Protrusion and the gradient of groove are big, reduce forming energy when forging, improve mold
Service life.
Detailed description of the invention
Fig. 1 is cross-sectional view of the invention.
Wherein: 1, upper mold；2, upper mold core；3, raised；4, groove；5, lower die；6, lower mold core；7, arc sections.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings:
As shown in Figure 1, the present invention includes upper mold 1 and lower die 5, the center of upper mold 1 is equipped with upper mold core 2,5 center of lower die
Position corresponds to upper mold core 2 equipped with lower mold core 6.The end face of upper mold 1 and the end face of lower die 5 are plane, the end face of upper mold 1 and lower die
5 end face fits.The upper mold 1 in 2 outside of upper mold core is equipped with the protrusion 3 around upper mold core 2, the position of respective protrusions 3 in lower die 5
Install fluted 4.The outside of protrusion 3 is in contact position with 1 end face of upper mold equipped with arc sections 7, the outside and 5 end of lower die of groove 4
Face is in contact position equipped with arc sections 7.The cross section of protrusion 3 is " U "-shaped, and the cross section of groove 4 is inShape.When processing,
The type for being put into lower die 5 by the processed blank of Preform Die is intracavitary, then upper mold 1 and 5 closed-die forging of lower die are formed, obtained
To final forging.
The present invention uses closed-die forging, saves raw material, improves the utilization rate of raw material.
The above is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention.This field it is common
Technical staff is appreciated that without departing from the principle and spirit of the present invention can be a variety of to the progress of these embodiments
Variation, modification, replacement and deformation.The scope of the present invention is defined by the claims and their equivalents.
