Description
Technical field
The Wedge type shaped the present invention relates to the production method of VL cage and VL type cage radially scalable core shaft structure and
It is applied.
Background technique
With science and technology progress, the raising of industrialization degree, more and more parts using pressure processing (forging,
Rolling, is rolled) forming technology.VL type cage is produced, due to being difficult to realize demould after inclined plane forming, existing market
Upper VL type cage generallys use the composite structure of two parts fission, and the part with inclined plane is processed using cutting process,
Two parts are combined with bolt again.Combined type cage mechanical strength is low, stability is poor, and production efficiency is low, and consumptive material is big and adds
Energy consumption is high for work, is not suitable for the social orientation of energy conservation.Therefore, realize that the pressure processing forming technology of VL type cage is raw
It produces, simplifies production link, save production cost, reducing energy consumption is that current cage production industry primarily solves the problems, such as.
Summary of the invention
Goal of the invention: the purpose of the invention is to overcome the deficiencies of the prior art and provide one kind VL type may be implemented
The radial extension type mandrel that cage is produced by pressure processing method.
In order to solve the above technical problems, the present invention adopts the following technical scheme: a kind of Wedge type diameter of VL type cage forming
To scalable mandrel, including mandrel inclined wedge, mandrel inclined wedge is fixed on lathe, mandrel inclined wedge and inclined plane by inclined wedge fixing seat
Convex block is linked by the T-type pulling plug portion component A；The outer rim of mandrel inclined wedge is arranged mandrel housing；Mandrel backhaul pull rod is outside mandrel
Set, and vertical with inclined wedge fixing seat connect；Mandrel backhaul pull rod between mandrel housing and inclined wedge fixing seat, outer rim are set
Inclined wedge reset spring.
The portion A includes T-type pulling plug, T-type pulling plug fixed pin, T-type pulling plug roller bolt, and T-type pulling plug roller bolt is set to mandrel
In the T-slot of inclined wedge, T-type pulling plug fixed pin is fixed on inclined plane convex block, and T-type pulling plug fixed pin draws hitching post and T by T-type
The linkage of type pulling plug roller bolt.
A kind of application method of the radial scalable mandrel of the Wedge type of VL type cage forming, including step
(a) shape original state: blank is put into cavity plate, and mandrel is set to above cavity plate；
(b) mandrel downlink and contact blank: mandrel downlink, until mandrel bottom surface is contacted with blank, mandrel housing is prevented from
Continue to move down；
(c) mandrel inclined wedge downlink inclined plane convex block is stretched out: inclined wedge reset spring is compressed, and mandrel inclined wedge continues traveling downwardly,
Inclined plane convex block in mandrel is released by mandrel inclined wedge, i.e. inclined plane convex block is stretched out；
(d) radial formed punch press molding: mandrel inclined wedge and mandrel housing rigid contact, mandrel are in extended state and constitute
The inside cavity shape of VL type cage pressure processing forming；Mandrel pressurization locking, 3 radial formed punches carry out radial pressurization, realize VL
The pressure processing of type cage shapes；
(e) radial formed punch backhaul inclined plane convex block is shunk: after the completion of radial formed punch press molding, radial formed punch backhaul,
Mandrel moves up, and the inclined plane convex block in mandrel pulls to center by mandrel inclined wedge, realizes the contraction of inclined plane convex block；
(f) mandrel deviates from drip molding: after inclined plane convex block is shunk, the radial scalable core of Wedge type of VL type cage forming
Mandrel backhaul pull rod in axis pulls out mandrel housing from drip molding, completes pressure processing forming.
When contacting blank, mandrel housing is compressed mandrel by inclined wedge reset spring in the step (b).
Mandrel is after contacting blank in the step (c), and when continuing to push, mandrel inclined wedge uses cylindrical surface and mandrel housing
Inner wall, which carries out guiding sliding, to be continued to move down, and is pushed outwardly inclined plane convex block by the circular conical surface of front end.
Mandrel inclined wedge continues to push in the step (c), until stop behind the upper surface of contact mandrel housing at step, this
When inclined plane convex block reach shaping position；The shape of mandrel is accurately controlled by the rigid contact of mandrel inclined wedge and mandrel housing
Size.
In the step (d) when radial formed punch press molding, inclined plane convex block is complete by circular conical surface with mandrel inclined wedge
Contact obtains rigid support, guarantees that mandrel (assembly) can bear powerful pressure when radial formed punch press molding.
Mandrel inclined wedge in the step (e) moves up under the action of inclined wedge reset spring, by mandrel inclined wedge
T-slot inclined plane convex block, T-type pulling plug column, T-type pulling plug fixed pin, T-type pulling plug roller bolt are returned to initial position.Phase
Between 9#T type pulling plug roller bolt rolled in T-slot, reduce abrasion.
Beneficial effect
The present invention makes mandrel (mold) after forming can by the design telescopic core shaft structure of inclined plane convex portion
Enough smoothly abjection, the pressure processing mode for realizing VL type cage produce.
To which energy consumption compared with traditional machining process, can be effectively reduced, material is saved, improves production efficiency,
The mechanical performance for improving workpiece to be machined effectively improves economic benefit, improves the market competitiveness, present invention process is simple, beneficial
Effect is obvious, convenient for promoting the use of.
