Description
Technical field
The automotive hub outer ring that the utility model is related to automobile using makes processing mold, especially automotive hub outer ring forging
Precise forming mold.
Background technology
Automobile hub bearing outer ring is installed on automobile wheel edge, and power transmission and supporting role are played with inner ring collective effect,
It is the important safety part on automobile, the safety traffic for automobile is extremely important.The traditional processing of automobile hub bearing outer ring
Mode is is machined after hot forging, because Product processing is remaining big, the material machined away is more, and stock utilization is only 55%
Left and right, and mach processing capacity is larger, process time compared with it is long, processing card it is big, cause production efficiency low, and produce
Product mechanical strength is weaker（It is relatively low）, it is weakened as the security performance of safety component, necessarily affects running car system
Security performance.
The content of the invention
The utility model adds for the said goods existing for the making machine-shaping of automotive hub outer ring forging in the prior art
Work card is big, stock utilization bottom, product strength are weak, under low production efficiency the deficiencies of, there is provided a kind of automotive hub outer ring forging
Precise forming mold, to improve Product processing efficiency, and then increase security by improving product strength.
The technical solution of the utility model：Automotive hub outer ring forging precise forming mold, the structure with upper die and lower die
Into upper mould, which includes upper mold core, upper guide collar and the upper mould of shaping, lower mould, includes forming lower die, forming lower die core and lower retainer plate；Its
It is characterised by：The lower surface of upper mold core, the first appearance material groove is provided with, first, which holds material groove, is inwardly recessed, under upper mold core
End face forms at least one cavity to concave.
Further feature is：In the upper surface of lower mold core, the second appearance material groove is provided with, second, which holds material groove, concaves
Enter, at least one cavity to concave is formed in the upper surface of lower mold core.
Lower push rod is provided with lower mould, the upper end of lower push rod holds with second expects that groove location is corresponding.
The utility model automotive hub outer ring forging precise forming mold, relative to prior art, there is following feature：
1st, using precision forming mold structure, can be refined Product processing allowance, and diameter can be reduced with length direction surplus
0.50-075mm, lifts product size precision, and stock utilization reaches 78%；Product mechanical strength lifting simultaneously 25%, it is significantly excellent
Change the Product Process.
2nd, the appearance material groove set in the forming face of shaping upper mold core or/and shaping upper mold core, it can be forged and pressed in product
Allow unnecessary clout to stay in appearance material groove when being formed into final stage, reduce mold cavity pressure more than 30%, reduce mould and open
Risk is split, improves die life 50% or so.
Brief description of the drawings
Fig. 1 the utility model deep slot type mould structure front views；
Fig. 2 is that the utility model holds material groove structure enlarged drawing.
Embodiment
As shown in Figure 1, 2, automotive hub outer ring forging precise forming mold of the present utility model, with upper die and lower die
Form, upper mould includes upper mold core 1, upper guide collar 2 and the upper mould 3 of shaping, and lower mould includes forming lower die 4, forming lower die core 5 and lower solid
Surely 6 are enclosed, workpiece is ejected into die cavity when being provided with lower push rod 7 on lower mould and being used to be stripped；Upper mold core 1 is arranged in the upper mould 3 of shaping
Between, lower mold core 5 is arranged among forming lower die 4, upper mold core 1 and the position correspondence of lower mold core 5, work is formed between upper mould 3 and lower mould 4
The forming recess of part；Part same as the prior art above, is not described further.
Automotive hub outer ring forging precise forming mold of the present utility model, the lower surface of upper mold core 1, is provided with the first appearance
Expect groove 10, hold material groove 10 and be inwardly recessed, the cavity of at least one indent is formed in the lower surface of upper mold core 1；In lower mold core 5
Upper surface, be provided with the second appearance material groove 11, second, which holds material groove 11, is inwardly recessed, formed in the upper surface of lower mold core 5 to
The cavity of a few indent；The forming face of upper mold core 1（Lower surface）, lower mold core 5 forming face（Upper surface）, different from routine into
Shape core rod end face form（Typically plane）, appearance material groove is provided with, forms one or more cavitys to concave, the appearance material is recessed
The effect of groove is at the product excellent suitability for press forming stage to the end, allows unnecessary clout to stay in cavity.The upper end of lower push rod 7 and the
Two hold the material position correspondence of groove 11, and shape is coincide.
Described first, which holds material groove 10, second, holds material groove 11, and its structure has a variety of, both can be a groove knot
Structure, from the lower surface of upper mold core 1（The upper surface of lower mold core 5）One end lead to the other end or multiple small inner cavities,
Needs of the present utility model can be met.
Precision forming mold of the present utility model, the course of work are：Under forcing press effect, top shoe drives part of the upper die
Move downward.Guide collar 2 is formed with the outer ring of forming lower die 4 and is oriented in the first step, guiding accuracy≤0.25mm.In second step shaping
Mould 3 closes with forming lower die 4, forms the forming recess of workpiece, and forges and presses workpiece configurations.3rd step shapes upper mold core 1 to moving down
It is dynamic to be moved up with forming lower die core 5, and workpiece is extruded respectively, extruding force progressively increases, upper and lower core rod end face（Forming face）'s
Hold material groove 10 to start to play a role, unnecessary clout, which flows into, to be held in material groove 10, reduces clout to die cavity inner wall pressure.With forging
The further progress of pressure, workpiece, which progressively shapes, reaches size and Geometrical Tolerance Principle, forms the automotive hub for meeting technological requirement
Outer ring forging.
It is last it should be noted that above example is only illustrating the technical solution of the utility model rather than restriction technologies
Scheme, although the utility model is described in detail with reference to preferred embodiment by applicant, one of ordinary skill in the art
It should be appreciated that the technical solution of the utility model is modified for those or equivalent substitution, without departing from the technical program
Objective and scope, it all should cover among right of the present utility model.
