Abstract
The invention discloses a baseball bat and a manufacturing method of the baseball bat. The baseball bat is completely made of TC4 titanium alloy. The baseball bat is hollow. The tensile strength of the TC4 titanium alloy is greater than 900 MPa. The TC4 titanium alloy comprises 4-6.5% of aluminum and 2.5-5.5% of vanadium in terms of weight percentage. The invention aims to provide the baseball bat and the manufacturing method of the baseball bat, and the baseball bat has the advantages of good strength, good elasticity, small density and difficulty in breaking.
Description
Technical field
the present invention relates to a kind of baseball bat and manufacture method thereof, particularly a kind of titanium alloy bar bat and manufacture method thereof.
Background technology
the material of current baseball bat generally has timber, aluminium alloy, three kinds, matrix material.Although wherein timber has extraordinary elasticity and toughness, in use easily fracture; Although duralumin generally uses, its elasticity does not have the good springiness of timber, and intensity can only reach below 600MPa; And the cost of matrix material is very high, toughness is poor, also easily fractures.
Summary of the invention
for the problems referred to above, the object of this invention is to provide a kind of baseball bat and manufacture method thereof, the intensity of baseball bat is good, good springiness, density are little, be not easy to fracture.
for solving the problems of the technologies described above, the technical solution used in the present invention is:
a kind of baseball bat, described baseball bat is all made up of TC4 titanium alloy.
preferably, described baseball bat is hollow.
preferably, the tensile strength of described TC4 titanium alloy is greater than 900MPa.
preferably, described baseball bat is one of the forming.
preferably, described TC4 titanium alloy comprise weight percent be 4 ~ 6.5% aluminium and weight percent be the vanadium of 2.5 ~ 5.5%.
more preferably, the content of described TC4 Oxygen in Titanium Alloy is less than 1000ppm.
more preferably, in described TC4 titanium alloy, the content of iron is less than 800ppm.
a kind of manufacture method of above-mentioned baseball bat, aluminium and vanadium is added in titanium sponge, melting, forging, extruding are made into TC4 pipe, carry out figuring of surface to TC4 pipe, are made into TC4 pipe fitting by press working, described TC4 pipe fitting be hollow and there are open front-end and back-end, the external diameter of rear end is less than the external diameter of front end, carries out closing in and closes, be heated to 300 ~ 900 DEG C to front end, carry out closing in rear end to close, obtained baseball bat.
the present invention adopts above technical scheme, and tool has the following advantages compared to existing technology: adopt TC4 titanium alloy to make, intensity is high, compare aluminium alloy and improve 40%, density is little, good springiness, be not easy to fracture, moderate cost, high comprehensive performance.This excellent performance makes baseball bat in shots, existing extraordinary intensity, is not easy to fracture, and also has good elasticity, laborsaving and can impact out farther distance.Overcome that wood materials easily fractures, aluminum alloy material elasticity is not enough, cost only has 30% of carbon fiber simultaneously.
Embodiment
below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be those skilled in the art will recognize that thus make more explicit defining to protection scope of the present invention.
a kind of baseball bat, described baseball bat is all integrally formed by TC4 titanium alloy and make.Described baseball bat has the holding end being positioned at anterior strike section and being positioned at rear portion, and wherein the external diameter of the section of strike is greater than the external diameter of holding end.Described baseball bat is hollow, and its inside is formed with the cavity of a base closed, with further weight reduction, and increases the elasticity of baseball bat.The present invention selects tensile strength to be greater than the TC4 titanium alloy of 900MPa.Particularly, described TC4 titanium alloy comprise weight percent be 4 ~ 6.5% aluminium and weight percent be the vanadium of 2.5 ~ 5.5%.The content of described TC4 Oxygen in Titanium Alloy is less than 1000ppm.In described TC4 titanium alloy, the content of iron is less than 800ppm.
a kind of manufacture method of above-mentioned baseball bat, detailed process is as follows: in titanium sponge, add aluminium and vanadium, melting in vacuum consumable electrode arc furnace, then be made into TC4 pipe through forging, extruding or cross piercing, figuring of surface carried out to TC4 pipe, is made into TC4 pipe fitting by press working, described TC4 pipe fitting be hollow and there are open front-end and back-end, the external diameter of rear end is less than the external diameter of front end, carries out closing in respectively close front-end and back-end, obtained baseball bat.Wherein when closing up closed to rear end, 300 ~ 900 DEG C must be heated to.TC4 titanium alloy low cost of manufacture, smelting technology is ripe, stable and reliable product quality.By cold and hot mode of rolling combination, the TC4 pipe fitting crystal grain molded is tiny, and over-all properties is that aluminium alloy and timber are irreplaceable.
the TC4 addressed in the present invention is a kind of titanium alloy, and it has, and density is little, intensity is high, the feature of good toughness, and its strength ratio aluminium alloy is high by 40%, and cost only has 1/3rd of carbon-fibre composite, is the best materials that baseball bat uses.Specifically compare in table 1 baseball bat material capability.
table 1 baseball bat material capability compares
| Material | Intensity | Cost | Plasticity | Elasticity | Applicable cases |
| Timber | Minimum | Minimum | The poorest | Good | Be only suitable for occupation match, easily fracture |
| Aluminium alloy | Within 600MPa | Low | Medium | Difference | Generally use, but intensity and poor flexibility |
| Carbon fiber | More than 900MPa | The highest | Difference | Medium | Do not use, cost is too high |
| Titanium alloy | More than 900MPa | Medium | Good | Good | Moderate cost, intensity is high, good springiness, and promotion prospect is good |
the baseball bat be made up of TC4 titanium alloy of the present invention, through performance test, meets service requirements completely.The strength ratio aluminium alloy of baseball bat improves 40%, density is low, good springiness, be not easy to fracture, moderate cost, high comprehensive performance.This excellent combining properties makes baseball bat in shots, and existing very good intensity, is not easy to fracture, also has good elasticity, laborsaving and can impact out farther distance.Overcome that wood materials easily fractures, aluminum alloy material elasticity be not enough, simultaneously cost only have 30% of carbon fiber.
above-described embodiment for technical conceive of the present invention and feature are described, is only a kind of preferred embodiment, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.The equivalence change that all spirit according to the present invention are done or modification, all should be encompassed within protection scope of the present invention.
