Description
Technical field
The utility model relates to a kind of titanium alloy casting technology for making, particularly a kind of titanium alloy golf club head casting feeding device.
Background technology
Because titanium alloy light specific gravity, intensity height are widely used in titanium alloy precision casting golf club field at present.The titanium alloys fabrication technique that is widely used in the titanium alloy precision casting golf club at present mainly contains casting and forges two kinds, the material of casting has advantages such as clear melodious and appearance and size is stable, with respect to forging the scope of attack, the titanium alloy scope of attack of casting belongs to the high-end field in golf club market.But because the titanium alloy setting rate is fast, shrinkage cavity trend is very obvious, and the scope of attack will bear the above batting impulsive force of 50m/s usually, shrinkage cavity defect will have a strong impact on the intensity of the scope of attack and cause fracture in advance, therefore it is high for the casting technique requirement to cast the scope of attack, and the casting scope of attack belongs to the highly difficult field of Ti alloy casting.The scope of attack is designed to pursue the batting performance in recent years, and to not uniform thickness development, this is for Ti alloy casting new challenge especially.
Prior art mainly contains three kinds:
First kind is the runner UNICOM thickened area of using less than the 1mm height.Concrete scheme is that the auxiliary outward running channel of diameter 6-8mm of autonomous cast gate overlap joint is connected with interior auxiliary flow, and outer auxiliary flow is less than the 1mm height, and outer auxiliary flow is connected with thickened area and produces the feeding effect simultaneously.The problem and the shortcoming of this kind technology comprise: though thickened area shrinkage cavity ratio reduces, the great shrinkage cavity probability in runner and thickened area junction still has a strong impact on quality gradually up to 100%, the runner height during greater than 1mm shrinkage cavity but more serious; Overlap the processes expend titanium material of the auxiliary running channel of a diameter 6-8mm, the production cost increase is bigger.
Second kind is to add feeding head in the scope of attack or the thick district of the scope of attack.Concrete scheme is the feeding head that thick district, scope of attack center directly adds diameter 20-25mm, produces feeding for the center.The problem of this kind technology and shortcoming: still below rising head, just ratio reduces, and still can influence intensity in shrinkage cavity; Rising head is excessive, grinds difficulty, and shape, radian are difficult to control.
The third is to forge after the scope of attack casting again.Concrete scheme is following to be that the scope of attack uses the normal process casting, is to forge with mould under the high temperature, and shrinkage cavity is eliminated.The problem of this kind technology and shortcoming A. Forging Technology complexity, it is higher to increase cost; Forge back thickness and be difficult to control, percent defective is higher.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of titanium alloy golf club head casting feeding device, thereby can improve the inside quality of the casting scope of attack: make the shrinkage cavity of foundry goods carve the reduction of weldering ratio, center intensity district cloud form shrinkage porosite ratio reduces, and reduces the intensity hidden danger that the shrinkage cavity repair welding causes greatly; Reduce cost, comprise and reduce foundry goods running channel overlap joint quantity, reduce the material and the cost of labor of engraving, repair welding shrinkage cavity simultaneously to reduce titanium material input; Set up the simplification flow process by what reduce auxiliary running channel, thereby save cost of labor and material cost.
For the purpose that realizes solving the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of titanium alloy golf club head casting feeding device of the present utility model, comprise main running channel, it is characterized in that: scope of attack feeding device is set between scope of attack center and main running channel, the feeding device be the height of a variable cross-section greater than 1mm, width interior auxiliary flow at 6-10mm, interior auxiliary flow two ends be connected main cast gate and scope of attack center respectively; The autonomous cast gate in the cross section of interior auxiliary flow definitely reduces to scope of attack central area direction.
Further, a kind of titanium alloy golf club head casting feeding device of the present utility model, interior auxiliary flow cross sectional shape is a rectangle or near oval.Further, the Aspect Ratio of rectangle is 5 ~ 10:1; Nearly oval-shaped major and minor axis ratio is 5 ~ 10:1.
The computing formula of the cross section parameter of auxiliary flow is in a kind of titanium alloy golf club head casting feeding device of the present utility model: H=1.0+0.14L, H: runner height, L: flow channel length, unit: mm.
Titanium alloy golf club head of the present invention is cast all necessary continuous transition in R angle of feeding device and scope of attack center and main cast gate junction, and the wedge angle less than R1 of the abrupt change of cross-section can not be arranged.
The interior auxiliary flow of titanium alloy golf club head casting feeding device of the present invention uses material consistent with main running channel, is the titanium alloy material.
Technique scheme is by the performance of macromethod shrinkage cavity and position distribution, and in conjunction with Ti alloy casting theory and Hydrodynamics Theory, obtains through contrast test repeatedly.
Principle of the present invention mainly is the consecutive solidification principle of metal.For example, reduce foundry goods running channel overlap joint quantity to reduce titanium material input, simultaneously because inside quality improves the material and the cost of labor that can reduce engraving, repair welding shrinkage cavity; Reduce setting up of auxiliary running channel, can save a large amount of costs of labor and material cost.Can improve simultaneously the inside quality of the casting scope of attack: make the shrinkage cavity of foundry goods carve the weldering ratio and reduce to 20% by original 60%, center intensity district cloud form shrinkage porosite ratio reduces to 5% by 80%, reduces the intensity hidden danger that the shrinkage cavity repair welding causes greatly; Improved the foundry goods inside quality greatly.
These technical schemes comprise that improved technical scheme and further improved technical scheme also can make up mutually or combination, thereby reach better technique effect.
By adopting technique scheme, the utlity model has following beneficial effect:
Use Ti alloy casting scope of attack inside quality of the present invention and obtain tremendous increase, shrinkage cavity is carved the weldering ratio and is reduced to 20% by original 60%, and center intensity district cloud form shrinkage porosite ratio reduces to 5% by 80%, and the ultimate strength and the fatigue strength of the scope of attack are significantly improved.
