Increase surface area；
First time phospholeum: product is first put into pickling in pickling tube, is then placed in phosphating pond and adsorbs phosphate coating, finally
It is put into absorption saponification layer in saponification pond；
Jumping-up: jumping-up is carried out to bar using heading die, obtains preforming forging stock, preforming forging stock includes top half
Circle drum body and lower half portion cylindrical body, the preforming forging stock circle drum body diameter by top to bottom become larger to
It is equal that the diameter maximum of cross section gradually becomes smaller the diameter to the pre- cylindrical body again；
Partial annealing: it is annealed using annealing furnace to jumping-up forging stock, to remove its internal stress；
Second of ball blast: carrying out ball blast cleaning using surface of the shot-blasting machine to rodlike forging stock, to remove its surface scale,
Increase surface area:
Second of phospholeum: product is first put into pickling in pickling tube, is then placed in phosphating pond and adsorbs phosphate coating, finally
It is put into absorption saponification layer in saponification pond；
Molding: by the die cavity of jumping-up forging stock merging finishing mold, squeezing shaping is carried out to jumping-up blank and goes out rounded corner, is obtained
Obtain precisive shaped forging stock.
In some embodiments, spheroidizing: after shaft furnace temperature is heated to 720 DEG C, heat preservation 3 hours, temperature drop
To 690 DEG C, temperature is kept for 5 hours, and subsequent temperature is down to 480 DEG C and comes out of the stove.
It has the advantage that: the present invention selects rodlike forging stock in blanking, being easy to prepare in jumping-up includes top half
Circle drum body and lower half portion the preforming forging stock of cylindrical body；Preforming forging stock made of jumping-up step of the invention be easy at
The type stage squeezes out fillet, solves such product precisive shaped interior raceway groove full of outer rounded corner, avoids the generation of casting skin, improves
The quality of product.

Specific embodiment
The present invention will be further described below with reference to the drawings.
Processing method the present invention provides star-wheel channel casting skin in a kind of solution includes blanking, spheroidizing, first time
Ball blast, first time phospholeum, jumping-up, partial annealing, second of ball blast, second of phospholeum and molding.Fig. 1 is schematically shown
Show in the solution of one embodiment of the present invention corresponding to the blanking of the processing method of star-wheel channel casting skin, jumping-up and molding
Product.Fig. 1 schematically shows the processing method institute of star-wheel channel casting skin in the solution of one embodiment of the present invention
Finished product obtained.
Blanking is to obtain rodlike forging stock.As shown in Figure 1, rodlike forging stock is cylindrical shape.Spheroidizing is by shaft furnace temperature
After degree is heated to 720 DEG C, heat preservation 3-3.5 hours, temperature drops to 690 DEG C, and temperature is kept for 5-5.5 hours, and subsequent temperature is down to 460-
500 DEG C are come out of the stove.Specifically, spheroidizing is after shaft furnace temperature to be heated to 720 DEG C, heat preservation 3 hours, and temperature drops to 690 DEG C,
Temperature is kept for 5 hours, and subsequent temperature is down to 480 DEG C and comes out of the stove.It is annealed using annealing furnace to rodlike forging stock, is answered inside it with removing
Power.First time ball blast is to carry out ball blast cleaning using surface of the shot-blasting machine to rodlike forging stock, to remove its surface scale, is increased
Surface area.First time phospholeum, which turns to, is first put into pickling in pickling tube for product, is then placed in phosphating pond and adsorbs phosphate coating, finally
It is put into absorption saponification layer in saponification pond.Using the forging of phosphorus saponification process, wearability is substantially increased, and process layer makes deformable metal
It is separated with mold, avoids between them and contact, die cavity will not be torn to shreds, thus improve the working life of mold.Upsetting
Thick is to carry out jumping-up to bar using heading die, obtains preforming forging stock.As shown in Figure 1, preforming forging stock includes the upper half
The diameter of the cylindrical body of the circle drum body and lower half portion that divide, the circle drum body of the preforming forging stock is become larger by top to bottom
It is equal that diameter maximum to cross section gradually becomes smaller the diameter to the pre- cylindrical body again.Preforming forging stock is bonded mold, by
This makes preforming forging stock rounded corner out easy to process in the forming step in later period.So that the interior raceway groove of interior star-wheel is full of outer circle
Chamfering avoids the generation of casting skin.Partial annealing is to be annealed using annealing furnace to jumping-up forging stock, is answered inside it with removing
Power.Second of ball blast is to carry out ball blast cleaning using surface of the shot-blasting machine to rodlike forging stock, to remove its surface scale, is increased
Surface area.Second of phospholeum, which turns to, is first put into pickling in pickling tube for product, is then placed in phosphating pond and adsorbs phosphate coating, finally
It is put into absorption saponification layer in saponification pond.Using the forging of phosphorus saponification process, wearability is substantially increased, and process layer makes deformable metal
It is separated with mold, avoids between them and contact, die cavity will not be torn to shreds, thus improve the working life of mold.Such as
It shown in Fig. 1, is shaped in the die cavity that jumping-up forging stock is placed in finishing mold, squeezing shaping is carried out to jumping-up blank and goes out rounded corner,
Obtain precisive shaped forging stock.The interior raceway groove of the interior star-wheel of precisive shaped is full of rounded corner, and product quality is preferable.Manufactured interior star-wheel finished product
As shown in Figure 2.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, it is not taking off
Under the premise of from the invention design, various modifications and improvements can be made, and these are all within the scope of protection of the present invention.
