Description
Technical field
The utility model is related to spinning mold technical field more particularly to spinning mold self-regulation mandrels.
Background technology
Casting spinning is to carry out rotary squeezing to inner rim portion on the basis of low pressure casting, changes the shape at wheel rim position
The internal structure of shape and metal, molecule are in more highdensity fibrous arrangement, and opposite casting hub has lighter weight, higher
Mechanical property performance, better intensity, while product price is significantly less than forging product is cost-effective, casts first when spinning
By cast blank by drilling machine, the cast gate that casting generates is removed, preparation is made for later machining, then by cast blank
360 DEG C are heated to, purpose is that wheel hub is made to soften, and is convenient for spinning, and wheel rim position rotary squeezing is formed wheel rim by spinning roller
Shape, in spinning process, since slab temperature is higher, flange position axial dimension extremely easy tos produce variation, in order to control method
Blue change in size needs to install mandrel additional on spinning tail top, realizes to the progress axial dimension limitation of wheelboss flange face, but due to
Drilling machine precision problem, the equal disunity of cast gate podium level, if cast gate platform is too low, mandrel will be unable to play fixed function, if pouring
Mouth platform is excessively high, and mandrel meeting excessive compression cast gate causes the reversal deformation of flange, or even scrap, platform is too high or too low with one voice
It is unable to reach the purpose of control wheel hub size quality.
