Specific embodiment
The present invention will be further described below with reference to the drawings.
It is a kind of to solve the big processing method of the high scattered error of out star wheel soccer star, including blanking, first time ball blast, coating, heating, just
Crowded, jumping-up, anti-crowded, temperature control cooling, second of ball blast, pre-treatment, pre- finishing and finishing.Fig. 1 schematically shows the present invention
A kind of embodiment the blanking solved in the big processing method of the high scattered error of out star wheel soccer star, just squeezing, jumping-up, it is anti-squeeze, pre- essence
The structural schematic diagram of forging stock obtained by whole and finishing.
As shown in Figure 1, blanking is using circular saw that steel are sawed-off, acquisition bar forging stock.First time ball blast is to pass through throwing
Ball machine carries out Shot Blasting to the surface of bar forging stock.Bar forging stock surface impurity is removed, billet surface product is increased.Coating is to use
Electric circle heats bar, is heated to 180 DEG C~220 DEG C, carries out coating treatment with surface of the graphite liquid to rodlike forging stock,
Its surface is set to form one layer of uniform graphite linings.Be heated to be and bar heated with intermediate frequency furnace, temperature be heated to 860 DEG C~
900℃.The concentration of the graphite liquid is 18%~22%.As shown in Figure 1, just squeezing for after blanking forging stock carry out just squeeze with
Form preforming forging stock.The preforming forging stock is structure as a whole.The preforming forging stock include the first bar portion, the second bar portion and
Third bar portion.The top of first bar portion is connect with the bottom end of second bar portion, the top of second bar portion with it is described
The bottom end of third bar portion connects.In the central axes of first body of rod 11, the central axes of second body of rod 12 and second body of rod 12
Axis is located in a straight line.The diameter of first body of rod 11 is less than the diameter of second body of rod 12, second body of rod
12 diameter is less than the diameter of the third body of rod 13.The junction of first body of rod 11 and second body of rod 12 is chamfering
The junction of structure, second body of rod 12 and the third body of rod 13 is chamfering structure.As shown in Figure 1, jumping-up is to just crowded
The third body of rod 13 of forging stock afterwards carries out jumping-up, so that the diameter of the third body of rod 13 becomes larger and height becomes smaller.As shown in Figure 1, anti-
It squeezes and instead squeeze to be formed on the top of the third body of rod 13 to its inner recess for the third body of rod 13 to the forging stock after jumping-up
Inner cavity.Temperature control is cooled to eliminate the stress generated when product squeezes, improves hardness.Second of ball blast is to cooling by temperature control
The surface of preforming forging stock carries out Shot Blasting, removes anti-material extrusion surface scale, increases surface area.Pre-treatment is that will first pass through
The preforming forging stock of Shot Blasting is sequentially placed into pickling in pickling tube, is put into phosphating pond and adsorbs phosphate coating, is put into saponification pond
Absorption saponification layer.Using the forging of phosphorus saponification process, wearability is substantially increased, and process layer separates deformable metal with mold,
It avoids between them and contacts, die cavity will not be torn to shreds, thus improve the working life of mold.As shown in Figure 1, pre- essence
Whole is to squeeze obtained intracavity bottom progress backward extrusion to anti-, is bonded blank intracavity bottom angle preferably with trimming punch,
It ensure that the high stability of soccer star.As shown in Figure 1, finishing is that the forging stock after pre- finishing is put into the shaping die cavity of finishing mold
It is interior, shaping is carried out to the inner cavity of the forging stock, to form head cavity small in the end and big in the middle.
The present invention increases pre- finishing process on original Process ba- sis, by way of pre- finishing cold extrusion, counter will squeeze
Expect that intracavity bottom carries out preform, make instead to squeeze blank intracavity bottom angle and be preferably bonded with trimming punch, ensure that soccer star's height
Stability.Invention increases pre- finishing process together, and anti-material extrusion intracavity bottom is carried out preform, makes instead to squeeze blank inner cavity
Bottom angle is preferably bonded with trimming punch, ensure that the high stability of soccer star, improves the service life of warm forging formed punch, section
About artificial and die cost, improves production efficiency.
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.
