Abstract
一种用于制成品比如高尔夫球棒头(20)的一部分的镍-钨-铬合金。该镍-钨-铬合金的密度范围最好为由9.0g/cm3到10.5g/cm3,并且,它的Rockwell硬度的范围由50到92。该镍-钨-铬合金能够进行熔模铸造,以形成制成品。
Description
技术领域
本发明涉及一种用于制成品的高密度合金。更具体地说,本发明涉及用于铁质的高尔夫球棒的高密度合金。
背景技术
当今的材料不能提供足够高的设计灵活性,以适应某些制成品比如高尔夫球棒头的质量性能要求。通过以特定的比例将组成部分的粉末混合起来,并且随后将混合物加压和烧结形成高密度的本体可以调节金属材料的密度。然而,这种过程不必然产生金属合金,这是因为局部的组分(local composition)与主体组分(bulk composition)的差别相当大。进而,这样的烧结过程会出现制造上的困难,并且不能提供足够的机械性能。
熔模铸造是用来生产大量的金属物品比如高尔夫球棒头的一种众所周知并且简单的制造过程。高密度金属比如钼(10.2克每立方厘米(“g/cm3”)),钛(16.6g/cm3)和钨(19.3g/cm3)不能直接使用,这是因为这些高密度金属极其难熔。其它高密度金属比如金(19.3g/cm3),银(10.5g/cm3)和铂(21.4g/cm3)对于大体积低成本的物品来说太昂贵,并且,这些昂贵的金属没有所要求的机械性能。
铁(7.86g/cm3)和镍(8.90g/cm3)不是非常难熔,有很好的机械性能,并且对于大体积低成本物品来说价格合理。Fe-W和Ni-W的两相图证明在固体状态下镍能够比铁溶解更多的钨。在固体状态下镍能够溶解30%重量的钨,而钨在铁中的溶解度是有限的。进而,铁的密度比镍低,所以为了获得较高的密度需要更多的钨。这两个条件都使得在铁钨合金中为多相而不是希望的单一相,有一种金属之间的相,此相很脆并且很难抛光。进而,对于最后的加工来说单一相较好,单一相更容易研磨,并且有较好的耐腐蚀能力。
一种特定制成品是铁类型的高尔夫球棒头,它们典型地由不锈钢或者钛材料构成,并且典型地铸造成或者锻造成这些制成品。大多数打高尔夫球的人希望他们的铁质高尔夫球棒头具有较为宽容的较大的击球点,为了获得对在空中的球有低的重心,坚实的回声(a solidsound),击打过程中减小的振动以及外观上修边的顶部线(a trim topline for appearance)。不幸的是,当涉及到铁时,这些要求常常是彼此矛盾的。
使用由不同材料构成的铁质高尔夫球棒头使得某些先有技术的铁材料可以实现这些要求中的某些要求。
一个示例是授予Okumoto等人的美国专利号5228694,该专利公开了由不锈钢底部和球杆孔件构成的铁质球棒头,由块体模制组分或者类似物构成的芯,由钨和聚酰胺树脂构成的配重件,以及由用纤维增强的树脂构成的外壳体。
在美国专利号4792139,4798383,4792139和4884812中叙述了另一个示例,所有这些专利都授予Nagasaki等人,这些专利公开了一种由不锈钢构成的铁质球棒头,它带有一个用纤维增强的塑料背板,从而可以进行重量调节并进行理想的惯量矩调节。
在授予Fujimura等人的美国专利号4848747中叙述了另一个示例,这些专利公开了一种带有用纤维增强的塑料背板的铁质球棒头.以增加击球点。使用一个环固定该背板的位置。
在授予Nakanishi等人的美国专利号4928972和4964640中叙述了另一个示例,这些专利公开了一种由不锈钢构成的铁质球棒头,它有一个在后凹进部分中的纤维增强件,对于冲击和震动提供一个阻尼装置,它还带有用于增加惯量矩的装置,用于调节重心的装置,以及用于增加背板强度的装置。
另一个示例是授予Take的美国专利号5190290,该专利公开了一种铁质球棒头,它有一个金属本体,一个由重量轻的材料比如塑料构成的填充件,以及一个模制在金属本体和该填充件上的用纤维增强的树脂。
另一个示例是授予Oku的美国专利号5411264,该专利公开了一种金属本体,它有一个向后面伸展的凸缘和一个弹性的纤维面板,为的是提高惯量矩,并且将球棒头的震动减到最小。
另一个示例是授予Aizawa等人的美国专利号5472201,该专利公开了一种铁质球棒头,它带有一个由不锈钢构成的本体,一个由用纤维增强的树脂构成的面板,以及一个由一种金属构成的保护层,为的是提供较深的重心、并且减小冲击。
另一个示例是授予Meyer的美国专利号5326106,该专利公开了一种铁质高尔夫球棒头,它带有一个金属叶片部分和由一种重量轻的材料比如用纤维增强的树脂构成的球杆孔件。
另一个示例是授予Aizawa等人的美国专利号4664383,该专利公开了一种铁质高尔夫球棒头,它带有一个用多层增强的合成树脂覆盖的金属芯,为的是使得球的击打距离更远。
另一个示例是授予Yoneyama的美国专利号4667963,该专利公开了一种铁质高尔夫球棒头,它带有一个金属底部和一个由用纤维增强的树脂材料构成的填充件,为的是使得球的击打距离更远。
先有技术都没有公开一种铁质高尔夫球棒头,它由多种材料构成,重心低,减小震动,并且有较大的惯量矩。
发明内容

一种优选的制成品是高尔夫球棒头,最优选的是铁质的高尔夫球棒头,该高尔夫球棒头可以是一个轻击棒或者木级棒(wood)。在题为A Golf Club Head with an Insert Having Integral Tabs的美国专利号6238302和题为Putter Head的美国专利号6471600中公开了能够采用本发明的镍-钨-铬合金的这样的轻击棒,在这里将这些专利的全文结合进来作为参考。在题为Weighting System for a GolfClub Head的美国专利号6434811中公开了能够采用本发明的镍-钨-铬合金的这样的木级棒,在这里将该专利的全文结合进来作为参考。
如在图1-8中所示,按照第一实施例的铁质高尔夫球棒头整体地用附图标记20表示。该球棒头20最好由三个主要部件构成:一个周边件22,一个中心件24和一个面板26。该球棒头20的范围可以由L形铁头(l-iron)到高楔形铁头(lob-wedge),弧线角(loft angle)的范围最好由15度到60度。可以采用一种过程把三个主要部件组装成球棒头20,这种过程比如是在2002年9月20日提交的题为Methodfor Manufacturing Iron Golf Club Head的美国专利申请号10/065150中公开的过程,在这里将该专利的全文结合进来作为参考。
周边件22由本发明的镍-钨-铬合金构成。该周边件22有一个底壁28,一个由该底壁28的趾端向上伸展的趾壁30,一个靠近底壁28的根端由底壁28向上伸展的根壁32,以及一个在底壁28的根端由底壁28向外伸展的球杆孔件34。最好将球杆孔件34偏置。球杆孔件34有一个孔36,用来容纳一根轴,并且,当球棒头20处于未示出的击打高尔夫球的准备击球位置时,球杆孔件34最好在趾壁30的上端的下面。孔36最好穿过整个球杆孔件34伸展,提供一个短的直的中空的球杆孔件,比如在美国专利号4995609中公开的球杆孔件那样,在这里将该专利的有关部分结合进来作为参考。
底壁28最好有一个形成腔室的外表面,在球棒摆动的过程中该外表面与地面接触。如在图8中所示,底壁28的宽度“Ws”的范围最好为由1.00英寸到1.75英寸,最可取地为1.25英寸。底壁28也有长度“Ls”,由趾端到孔36的开始处,它的范围最好为由2.5英寸到3.5英寸,最可取地为3.0英寸。
如在图5中所示,趾壁30最好有一个长度“LT”,它的范围最好为由1.5英寸到2.5英寸,最可取地为2.0英寸。趾壁30最好有一定宽度,由趾壁30的下端到上端变窄。
如在图6中所示,根壁32最好有一个长度“LH”,它的范围最好为由0.5英寸到1.5英寸,最可取地为1.0英寸。根壁32最好有一个宽度,由根壁32的下端到上端变窄。
一般说来,周边件22使得球棒头20有较大的惯量矩,这是由于沿着球棒头20的周边它有相对较大的质量。进而,属于底壁28的质量降低了球棒头20的重心,在击打高尔夫球时有利于产生较高的轨道。周边件22最好占球棒头20的体积的15%到50%,并且最好占球棒头20的质量的50%到80%。
中心件24由一种非金属材料构成,优选的材料包括块体模制的复合物,薄片模制的复合物,热固化材料,以及热塑性材料。一种优选的块体模制复合物是带有增强纤维的树脂材料。这样的树脂包括聚酯,乙烯酯,以及环氧树脂。这样的纤维包括碳纤维,玻璃纤维,芳族聚酰胺,或者它们的组合。优选的薄片模制复合物与块体模制复合物类似,然而其形式为薄片形式。优选的热塑性材料包括与比如上面公开的那些纤维集成在一起的可以注入模制的材料。这些热塑性材料包括聚酯,聚乙烯,聚酰胺,聚丙烯,聚氨酯,以及类似材料。
中心件24主要是一个用于面板26的支承件,因此,该中心件应该能够经受冲击作用力,而不会损坏。该中心件24也可以减小在击打球期间球棒头20的振动。中心件24最好占球棒头20的体积的25%到75%,并且最好占球棒头20的质量的10%到30%。
中心件24最好有一个本体部分38,一个凹进部分40,一个前表面42,一个后表面43,一个底表面44,一个顶表面46,一个趾表面48,一个根表面50以及一个凸缘52。前表面42的角度最好近似地为球棒头20的角度。因此,如果球棒头是一个5号铁头(5-iron),那么,前表面最好有一个大约27度的角度。本体部分38最好由底表面44向上变窄。
中心件24设置在周边件22的底壁28的内表面上。中心件24的趾表面48最好与周边件22的趾壁30的内表面接合。中心件24的根表面50最好与周边件22的根壁32接合。顶表面46最好产生球棒头20的顶部线。凸缘52由顶表面46向外在前表面42上方伸展,从而产生一个顶盖,为的是固定面板26。也把面板26紧固在周边件22的一个凸起边沿60内。
面板26最好由一种重量轻的材料构成。此重量轻的材料的密度最好比周边件的材料低。这样的重量轻的材料包括钛材料,不锈钢,无定形金属以及类似材料。这样的钛材料包括纯钛和钛合金,比如6-4钛合金,6-22-22钛合金,4-2钛合金,SP-700钛合金(可以由NipponSteel of Tokyo,Japan公司获得),可以由Diado Steel of Tokyo,Japan公司获得的DAT 55G钛合金,可以由RTI International Metalsof Ohio公司获得的Ti 10-2-3 Beta-C钛合金以及类似材料。最好通过铸造,锻造,成形,机械加工,粉末金属成形,金属注入模制(metal-in jection-molding),电化学研磨,以及类似方法制造出面板26。
面板26有一个内表面56和一个外表面54,该内表面最好与中心件24的前表面接合,而后表面最好在其上有刻痕线(未示出)。面板的厚度范围最好为由0.040英寸到0.250英寸,更可取地由0.06英寸到0.130英寸,而最可取地为0.075英寸。
球棒头20的总体积的范围最好为由40.0立方厘米到55.0立方厘米,更可取地由45.0立方厘米到55.0立方厘米,而最可取地为50.8立方厘米。球棒头20的质量范围最好为由240克到270克,更可取地由245克到260克,而最可取地为253克。
周边件22的总体积的范围最好为由10.0立方厘米到32.0立方厘米,更可取地由15.0立方厘米到20.0立方厘米,而最可取地为18.8立方厘米。周边件22的质量范围最好为由100克到240克,更可取地由150克到200克,而最可取地为185克。
中心件24的总体积的范围最好为由7.0立方厘米到35.0立方厘米,更可取地由15.0立方厘米到30.0立方厘米,而最可取地为28.0立方厘米。中心件24的质量范围最好为由9克到70克,更可取地由25克到60克,而最可取地为45克。
面板26的总体积的范围最好为由4.0立方厘米到8.0立方厘米,更可取地由4.5立方厘米到6.0立方厘米,而最可取地为5.3立方厘米。面板26的质量范围最好为由15克到50克,更可取地由20克到30克,而最可取地为24克。
图13-20示出了按照第二实施例的铁质高尔夫球棒头。该铁质高尔夫球棒头20’包括一个由本发明的镍-钨-铬合金构成的周边件22’,一个由一种非金属材料构成的中心件24’,以及一个由密度比周边件22’的材料低的一种金属材料构成的面板26’。
周边件22’与第一实施例的周边件22类似,并且有一个底壁28,一个趾壁30,一个根壁32以及一个球杆孔件34,此球杆孔件带有一个孔36,用来容纳一根轴。此外,周边件22′有一个顶壁32,此壁由趾壁30的上端伸展到根壁32的上端。顶壁62,底壁28,趾壁30和根壁32形成一个穿过周边件22′的开口64。对于底壁28,趾壁30和根壁32来说,周边件22’有与第一实施例的球棒头20的周边件22类似的尺寸。
周边件22’使得球棒头20’有较大的惯量矩,这是由于在球棒头20’的周边它有相对较大的质量。进而,属于底壁28的质量降低了球棒头20’的重心,在击打高尔夫球期间有利于产生较高的轨道。周边件22’最好占球棒头20’的体积的15%到50%,并且最好占球棒头20’的质量的50%到80%。
中心件24’由一种非金属材料构成,比如块体模制的复合物,薄片模制的复合物,热固化材料或热塑性材料。中心件24’支承着面板26,并且用来减小在击打球时球棒头20’的振动。中心件24’最好占球棒头20’的体积的25%到75%,并且最好占球棒头20’的质量的10%到30%。
中心件24’最好有一个本体部分38’,一个凹进部分40’,一个前表面42,一个后表面43,一个底表面44,一个顶表面46,一个趾表面48以及一个根表面50。在本体部分38’的后表面43中形成凹进部分40’,并且该凹进部分可以为大量的适当构形中的任何一个构形。本体部分22’最好由底表面44向上变窄。
中心件24’设置在周边件22’的开口64中,使底部44与周边件22’的底壁28的内表面接触。中心件24’的趾表面48最好与周边件22’的趾壁30的内表面接合。中心件24’的根表面50最好与周边件22’的根壁32接合。顶表面46最好与周边件22’的顶壁62的内表面接合。
面板26也设置在周边件22’的开口64中。最好把周边件22’模锻成把面板26固定在开口64中。替代地,也可以把面板26焊接到周边件22′上,或者用一种粘接剂把面板固定在其位置。面板26有一个内表面56和一个外表面54,该内表面最好与中心件24’的前表面42接合,而后表面最好有在其上形成的刻痕线55。如上面描述过的那样,面板26由一种重量轻的材料构成,并且,它的厚度范围最好为由0.040英寸到0.250英寸,更可取地由0.06英寸到0.130英寸,而最可取地为0.075英寸。
图9-12示出了穿过高尔夫球棒头的重心的惯量轴线。这些惯量轴线用X,Y和Z表示。X轴线由高尔夫球棒头20的后面穿过重心CG伸展到面板26。Y轴线由高尔夫球棒头20的根端75穿过重心CG伸展到高尔夫球棒头20的趾端70。Z轴线由底壁穿过重心CG伸展到顶部线80。
如在Ralph Maltby的Golf Club Design,Fitting,Alteration& Repair的第4版中定义的那样,高尔夫球棒头的重心或质心是由当把球棒头悬挂起来时它取得平衡的两点或更多点的竖直相交线确定出的在球棒头内部的一个点。在Golf Club Design,Fitting,Alteration & Repair中提供了对于重心的这个定义的更详尽的解释。
最好使用一个检验框架(XT,YT,ZT)随后转移到一个头部框架(XH,YH,ZH)上测量高尔夫球棒头20,20’的重心和惯量矩。可以使用在其上有两个称重天平的重心台获得高尔夫球棒头20的重心,如在2001年2月27日提交的题为High Moment of Inertia Composite GolfClub的正在共同未决的美国专利申请号09/796951中公开的那样,在这里将它的全文结合进来作为参考。如果存在一根轴,就将它移开,并且用一个球杆孔件立方体(hosel cube)替换它,该立方体有与高尔夫球棒头的轴线垂直的多个表面。给定了高尔夫球棒头的重量之后,当把高尔夫球棒头同时放在两个天平上并且沿着一个特定的方向即X方向,Y方向,或者Z方向称重时,两个天平使得可以确定出高尔夫球棒头的重量分布。
一般说来,本发明的高尔夫球棒头20,20’关于Z轴线的惯量矩Izz的范围最好由2200g-cm2到3000g-cm2,更可取地为由2400g-cm2到2700g-cm2,而最更可取地为由2472g-cm2到2617g-cm2。高尔夫球棒头20关于Y轴线的惯量矩Iyy的范围最好由400g-em2到700g-cm2,更可取地为由500g-cm2到600g-cm2,而最更可取地为由530g-cm2到560g-cm2。高尔夫球棒头20关于X轴线的惯量矩Ixx的范围最好由2450g-cm2到3200g-cm2,更可取地为由2500g-cm2到2900g-cm2,而最更可取地为由2650g-cm2到2870g-cm2。
为了作比较,Callaway Golf Company of Carlsbad,California公司的新的BIG BERTHA5-iron的惯量矩Izz为2185g-cm2,惯量矩Iyy为585g-cm2,惯量矩Ixx为2407g-cm2。
采用标准的开气(open-air)熔模铸造步骤通过对镍-钨-铬合金进行熔模铸造形成制成品。一般在1720摄氏度的温度下进行熔模铸造。最好采用1%重量的硅,使得在进行铸造的过程中在熔化物中的其它成分有流动性,这将使得可以充满薄壁并且减少砂眼。
