Abstract
The utility model discloses an aluminium wheel spinning mold sliding block mechanism which comprises a sliding block 3 and a fixing block 5, wherein a spring 4 is arranged between the sliding block 3 and a lower mold 6, a contact face between the fixing block 5 and the sliding block 3 is arranged to be a smooth curved surface, and the fixing block 5 is fixed with the lower mold 6 through bolts. The sliding block 3 can be moved along a track of the fixing block 5, the outer end portion of the sliding block can be stretched out and drawn back along the radial direction under effect of the spring and therefore a groove is added on a blank. The aluminium wheel spinning mold sliding block mechanism is capable of effectively eliminating the problem of stress concentration of a closed angle part, prolonging service life of molds, improving production efficiency and increasing economic benefits.
Description
Technical field
The utility model relates to a kind of aluminium wheel hub spinning mold.
Background technology
Along with going deep into of energy-saving and emission-reduction policy, environmental protection, efficient, the energy-conservation automobile industry focus that becomes.Except the trial of power in environmental protection, automotive light weight technology is to generally acknowledge at present the most minimizing energy consumption development path of reality.In vehicle body, engine, the chassis three large systems, the Lightweight Technology of chassis system and economic feasibility are more obvious.Wheel is center of gravity parts on the low side in the automobile chassis system, and its loss of weight is better than other chassis auto parts and components to the effect of automobile fuel saving.
Forged hub is to finish through work steps such as forging, spinning.In order to realize the light-weighted purpose of wheel, be one of measure at wheel rim and spoke position increase groove.
The utility model content
The purpose of this utility model provides a kind of improved slide block mechanism, prolongs die life.
The technical solution of the utility model is: a kind of spinning mould of aluminum wheel slide block mechanism, comprise slide block, fixed block, and between slide block and the counterdie spring is set, contact-making surface is set to smooth curved surface between fixed block and the slide block, and fixed block and counterdie are fixed with bolt.Slide block can carry out activity along the track of fixed block, and the slide block outer end can be flexible along radial direction under spring action, thereby increase groove at blank.
Described fixed block and slide block contact-making surface are the twisting smooth curved surface.
Described fixed block and slide block contact-making surface are the dove-tail form smooth curved surface.
Described fixed block and slide block contact-making surface are the waveform smooth curved surface.
The utility model can effectively solve slide block and the concentrated problem of fixed block stress in the prior art.
Description of drawings
With the specific embodiment the utility model is described further by reference to the accompanying drawings.
Fig. 1 is the structural representation on the utility model wheel die.
Fig. 2 is structural scheme of mechanism of the present utility model.
Fig. 3 is that the utility model fixed block and slide block A are to schematic diagram.
Among the figure: 1-patrix, 2-wheel blanks, 3-slide block, 4-spring, 5-fixed block, 6-counterdie.
The specific embodiment
A kind of spinning mould of aluminum wheel slide block mechanism comprises slide block 3, fixed block 5, between slide block 3 and the counterdie 6 spring 4 is set, and contact-making surface is set to smooth curved surface between fixed block 5 and the slide block 3, and fixed block 5 is fixed with counterdie 6 usefulness bolts.Slide block 3 can carry out activity along the track of fixed block 5, and slide block 3 outer ends can be flexible along radial direction under spring 4 effects, thereby increase groove at wheel blanks 2.
As shown in Figure 1, described fixed block 5 is the twisting smooth curved surface with slide block 3 contact-making surfaces.
As a kind of embodiment of the present utility model, described fixed block 5 is the dove-tail form smooth curved surface with slide block 3 contact-making surfaces.
As a kind of embodiment of the present utility model, described fixed block 5 is the waveform smooth curved surface with slide block 3 contact-making surfaces.
The utility model spinning mold slide block mechanism has effectively been eliminated the concentrated problem of stress at wedge angle position, has effectively prolonged the mold use life-span, has improved production efficiency, has improved economic benefit.Spinning mold with slide block mechanism is not limited to the scheme that the drawings and specific embodiments are described, and has the spinning mold of slide block mechanism all to fall into the scope that the utility model is protected.
