Tool 4 is dies for precise fooge of bevel gears.The fluid media (medium) for polishing polished mold 4 is provided between upper material cylinder 1 and lower material cylinder 10
9, fluid polishing pellet 3 is installed between upper material cylinder 1 and lower material cylinder 10, fluid polishing chip side wall is close to polished mold
4 burnishing surface, and there are the streams passed through for fluid media (medium) 9 between fluid polishing pellet 3 and the burnishing surface of polished mold 4
Road, runner are annularly arranged.Area of the runner in any radial section position of polished mold 4 is equal, i.e., fluid media (medium) 9 exists
The flow of any radial section position of polished mold 4 is identical, so that fluid media (medium) 9 be kept at the uniform velocity to flow through runner, and keep to
The pressure for the fluid media (medium) 9 that the burnishing surface of polishing 4 any position of mold is subject to is identical.In this way by runner in polished mold 4
The area of any radial section position is equal, i.e. realization cross-section runner, can achieve and fluid media (medium) 9 is kept at the uniform velocity to flow through
Uniform polish is realized in road, improves the precision for polishing polished mold 4.
Fixed polished mold 4 and fluid polishing pellet 3 for convenience, are equipped between upper material cylinder 1 and polished mold 4
Upper backup pad 2 is equipped with lower supporting plate 6 between lower material cylinder 10 and polished mold 4, by upper material cylinder 1, upper backup pad 2, to
It polishes mold 4, lower supporting plate 6 and lower material cylinder 10 and forms closed housing；And lower supporting plate 6 is provided with fixed fluid polishing pellet
The fixation kit of 3 relative positions, fixation kit include the cushion block 5 being set between fluid polishing pellet 3 and lower supporting plate 6, stream
It is equipped with bolt 8 between body polishing pellet 3, cushion block 5 and lower supporting plate 6, bolt 8 is threaded with nut 7, passes through bolt 8
And fluid polishing pellet 3, cushion block 5 are fixed on lower supporting plate 6 by nut 7.Pass through bolt 8 and nut 7, easy disassembly fluid polishing
Pellet 3, and it is conveniently replaceable polished mold 4.
To realize that the constant speed in runner of fluid media (medium) 9 flows, by designing 3 structure of fluid polished core block, so that runner
Area in each section in product type chamber range inner axis direction is kept constant.
Embodiment two: as shown in figure 5, utilizing bevel gear mold fluid media (medium) uniform flow polissoir described in embodiment one
Polishing method, include the following steps:
(a) fluid media (medium) 9 is placed in lower material cylinder 10, polished mold 4 is placed in lower supporting plate 6, and use bolt 8
Fluid polishing pellet 3, cushion block 5 are fixed on lower supporting plate 6, upper backup pad 2 is overlying on mould upper surface, fluid polishing pellet 3
The runner passed through for fluid media (medium) 9 is formed between polished mold 4；
(b) cavity pressure between upper material cylinder 1 and lower material cylinder 10 is preset, and sets fluid media (medium) 9 in upper material cylinder 1 and blanking
Number is back and forth flowed between cylinder 10；
(c) material cylinder 1 presses to upper backup pad 2 on, so that forming closed housing between upper material cylinder 1 and lower material cylinder 10；
(d) material cylinder 10 ejects fluid media (medium) 9 under, fluid media (medium) 9 flow through fluid polishing pellet 3 and polished mold 4 it
Between runner after enter feeding cylinder 1；Then upper material cylinder 1 depresses fluid media (medium) 9, fluid media (medium) 9 flow through fluid polishing pellet 3 with
Enter blanking cylinder 10 after runner between polished mold 4, flows, polished repeatedly；

In step (a), runner is any radial section in polished mold 4 between fluid polishing pellet 3 and polished mold 4
The area of face position is equal, and the fluid media (medium) 9 at the uniform velocity flows through runner arbitrary section position.
To ensure that runner is equal along the axial various cross-sectional areas of polished mold 4, reaches cross-section runner, calculate runner
Area of section process is as follows:
1, as shown in fig. 6, calculating the area of section S of circular ring shape runner:
S=π D2/4-π(D-2t)2/ 4=π Dt- π t2
When runner is smaller, t levels off to 0
S≈πDt
That is S=C*t (wherein C is perimeter of section).
2, as shown in fig. 7, the area of section S of square annular channel:
S=ab- (a-2t) (b-2t)=2at+2bt-4t2
When runner is smaller, t levels off to 0
S≈2at+2bt
=2 (a+b) t
That is S=C*t (wherein C is perimeter of section).
3, as shown in figure 8, special-shaped flow passage is made of multiple rectangles, circular cross-section,
When runner is smaller, t levels off to 0
Type chamber sectional area S:
S≈C*t
Therefore when designing fluid polishing pellet 3, it need to guarantee the area equation in each section,
That is S=C1*t1=C2*t2=C3*t3=C4*t4=...
Only need to guarantee that the perimeter C of runner different cross section position is equal with the product of corresponding runner clearance t.
