Embodiment
Below against accompanying drawing, by the description to embodiment, the embodiment to the present invention makees further details of
Explanation, it is therefore an objective to help those skilled in the art to have more complete, accurate and deep reason to design of the invention, technical scheme
Solution, and contribute to it to implement.
As shown in Figures 1 to 9, a kind of aluminium alloy wheel hub shear spinning mould emptier, including core mold structure, core mold structure bag
Inner core film 6 and the outer core being socketed on outside inner core film 6 are included, the mould emptier also includes the outer core for being used to move radially with stress
The confinement block 4 that mold lock is fastened and the limit telescopic machine for promoting core mold structure to move and drive outer core to depart from confinement block
Structure.
Limit telescopic mechanism includes gag lever post 2 and the spring 3 in the preceding guide channel of mould 1, and the promote-side of gag lever post 2 leads to
Spring 3 is crossed to be connected with preceding mould 1, and the promote-side of gag lever post 2 can promote core mold structure to move by the elastic reset of spring 3.When
Outer core stress is moved radially, spring spring-compressed, after outer core, which is moved to, coordinates locking with confining block, core now
For mould pressing, after wheel hub shaping, tail top 7 is moved to right, and gag lever post promotes inner core film to move to right under the force of a spring, when spacing
Bar is moved to right contacted with outer core after, continue to press on inner core film and moved to right with outer core, outer core is departed from the effect of contraction for confining block.
Confine block and be provided with screw thread, be easy to that fastening is mounted.
For the ease of demoulding, core mold structure includes the inner core die 6 with raised anti-sliding stop and outer core mold structure with groove.
Inner core die 6 is inclined plane cylindrical structure, and cone angle is 10 °~12 °；The cylinder of inner core die 6 has three raised and outer core cooperations, three
Projection is distributed in the periphery of inner core film so that inner core film can coordinate anti-skidding structure more to stablize with outer core.Outer core by
The structure that six corresponding valve blocks are combined, valve block structure includes three the first valve block structure 8-1 and three the second valve block structures
Adjacent enclose is coated on 6 weeks faces that lean outward of inner core film two-by-two by 8-2, the first valve block structure 8-1 and the second valve block structure 8-2；Outer core
The introversion face of mold section block structure 8 matches with inner core die 6；Outer core has three valve blocks (the first valve block structure) inner surface to have groove
Structure, mold-slide is prevented with the male cooperation of inner core die；Outer six valve block structure centers of core, respectively have one to rise and determine vertically
Position and the square hole of confinement effect.Aluminium alloy wheel hub complex geometry, wheel rim is usually irregular bent bus, is stripped after shaping
Difficulty, using the above-mentioned core mold structure for inlaying block structure, is easy to after shear spinning carry out demoulding, demoulding principle is simple, versatility
By force.
The course of work of demoulding of the present invention：As shown in figure 1, the left top of plate to left side core is fixed on tail top 7, it is now, interior
Core 6 is extruded to the left, and outer core stress is moved radially, and spring 3 is in compressive state, when outer core is moved to confining block
After 4 coordinate, core mold structure is in the lock state, and now core mold structure can be used for mould pressing.When core mold structure rotation, it can drive
Tail top and blank rotation.After wheel hub shaping, tail top 7 is moved to right, and gag lever post 2 promotes inner core die 6 to move to right under the active force of spring 3, when
Gag lever post 2 is moved to right contacted with outer core after, continue to press on inner core die 6 and moved to right with outer core, outer core is departed from the pact for confining block 4
Shu Zuoyong.Core mold structure as shown in Figure 2 and Figure 3, confines the completion of the effect of contraction of block 4 when departing from, and core will disintegrate, from shaping trailing wheel
Hub departs from.
For existing aluminium alloy wheel hub of vehicle spin forming technique, using thick aluminum plate stock as blank, many spinning roller techniques
To reduce spinning pass.Aluminium alloy wheel hub shaping uses slab shear spinning forming technique, and spinning roller form is as shown in fig. 6, spinning roller
Operating angle α is less than 90 °.As shown in fig. 7, arranging three spinning rollers 9 around core mold structure, sagittal plane within angle is 120 °；Along axle
To mistake away from arrangement, mistake is away from less than spinning roller radius, to reduce spinning pass.
The aluminium alloy wheel hub shear spinning shapes method, comprises the following steps：
Step one, plate top to core mold structure is fixed by tail top 7, is extruded inner core film 6, outer core stress
Move radially to confining block 4 and coordinate locking；
Step 2, rotates core mold structure, drives tail top 7 and plate rotation；
Step 3, wheel hub is shaped by taking turns spinning process more.
Many wheel spinning process realize that improvement of the invention is mainly reflected in its technique ginseng using existing spinning process technology
Several improvement, many wheel spinning process are preferably three spinning roller stepped spinning forming technologies, can effectively reduce spinning pass, spinning road
It is secondary to reduce than being 1:1.3~1.5, and any surface finish.The forming parameter of spinning roller stepped spinning forming technology is：
After a, the first spinning roller spinning of setting, plate reduction is 25%~30%；After second spinning roller spinning, reduction is
28%~33%；After 3rd spinning roller spinning, reduction is 100%, i.e. trimming, to ensure forming quality；Reduction is rotation
One important technological parameter of pressing formation, the selection of wall thickness reduction directly influences the product quality and economy of spinning production
Property, the selection of reduction is the primary factor for formulating reasonable spinning process, is set using the plate reduction after above-mentioned spinning roller spinning
Setting formula, enables to finished product product quality and economy to reach preferable level；
B, spinning roller radius of clean-up ρ are 11~14mm；
C, feed ratio are 0.8~0.9mm/r；Feed ratio, which is entered, refers to that core often rotates a circle, and spinning roller is moved along core bus
Distance, unit is mm/r.For the plastic deformation ability of aluminium alloy, repetition test, using 0.8~0.9mm/r feeding
Than being optimal feed ratio setting range；
D, mandrel rotary velocity are set as 2r/s.
The parameters such as reduction, spinning roller work arc radius, feed ratio and mandrel rotary velocity by optimizing above-mentioned setting, can
Effectively solve the defect that spinning aluminium alloy wheel hub easily tears, easily swelled.
The present invention is exemplarily described above in association with accompanying drawing.Obviously, the present invention is implemented not by above-mentioned side
The limitation of formula.As long as employ the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress；Or not
It is improved, the above-mentioned design of the present invention and technical scheme are directly applied into other occasions, in protection scope of the present invention
Within.
