Description
Technical field
The present invention relates to a kind of steel ball drop stamping mould.
Background technology
Diameter dimension is more than the steel ball of 25mm, feeds intake and uses drop stamping mode, i.e., the good material section of car is put into electric furnace
Heating, after material section is grilled thoroughly, takes out, is placed on compressing process between upper and lower punch die.Whole process needs to be carried out continuously,
Because of technological requirement per the time of stove material section heating, at the appointed time, it is necessary to complete all material section compactings in stove, more than work
The time range of skill requirement, the interior material section of stove, which will overheat, scraps.This requires processing staff by from stove feeding, compacting,
To blank process is removed from loose tool, accomplish without any letup, just can guarantee that will expect that section all complete by compacting at the appointed time in stove.It is whole
In a pressing process, do not require nothing more than operating personnel must skilled operation, and it is compressing after feeding is smooth from loose tool, does not glue
Tire, just can guarantee that and smoothly completes current amount and class's production quantity, avoid producing raw material waste product.
The loose tool that steel ball hot stamping procedure uses, generally spherical ball tire or cone cydariform ball tire, in processing diameter dimension
During more than 25mm steel balls, often occur " viscous tire " phenomenon, so-called " viscous tire " be exactly blank steel ball it is compressing after, blank ball is sticked to
On pressure ball tire, take out the blank ball such as difficulty, the viscous serious need of tire and somewhat cool down, operating personnel can just remove after being beaten with instrument.
There is viscous tire phenomenon, not only influence processing efficiency, increase the labor intensity of operator, can also make the other material heated in stove
Section, because of the heating time more than technological requirement, produces a large amount of waste products.
When processing the steel ball blanks of diameter 40mm or so, the pressure ball tire that is manufactured by the design method of original spherical ball tire,
" viscous tire " phenomenon is more serious, and can not normally be fed intake processing at all.
The content of the invention
The invention aims to solve existing large scale steel ball drop stamping to have " viscous tire " phenomenon, it can not ensure steel ball pressure
Smooth, the problem of raw material high rejection rate and labor intensity are big, production efficiency and low product quality of process processed, and provide a kind of
Size is the steel ball drop stamping mould of more than 25mm.
The steel ball drop stamping mould that a kind of size of the present invention is more than 25mm includes steel ball mold base body；The steel ball mould
The upper end center position of embryo body is provided with the spherical tire nest of cone drum, and the center of the steel ball mold base body is provided with centre hole, institute
The upper end for stating centre hole is connected with the spherical tire nest of cone drum；The top of the steel ball mold base body is round platform, and lower part is cylinder；
The side of the lower part of steel ball mold base body is cut with an inclined-plane, and the gradient on the inclined-plane is 1:7, under the steel ball mold base body
The bottom rounded corner in portion；The spherical tire nest of the cone drum includes the first arc-shaped changeover portion, the second arc-shaped changeover portion and the 3rd circle
Arc-shaped transition section；The tangent line on the first arc-shaped changeover portion vertex and horizontal angle are 75 °, the three-arc shape mistake
The intersection point tangent line and horizontal angle for crossing section lower end and centre hole upper end are 25 °, the first arc-shaped changeover portion and second
Intersection's rounding off of arc-shaped changeover portion, intersection's circle of second arc-shaped changeover portion and three-arc the shape changeover portion
Slip over and cross.
The present invention is used for the steel ball that drop stamping size is more than 25mm.
Beneficial effects of the present invention：
The hot pressing ball tire of the present invention, by multiple processing experiment, has put into normal batch of production, w is complete for " viscous tire " phenomenon
It totally disappeared and remove.Labor intensity and the non-cutting time of operator is alleviated, accelerates drop stamping rate of feeding, production efficiency improves
30%.Meanwhile reduce frock abrasion, extend mould service life, reduce mould and replace the frequency, reduce frock manufacture cost.
Other large scale steel ball hot pressing ball tires also can be according to said method designed, and after promoting the use of, can be greatly improved batch production and be fed intake efficiency.
