Technical field

The utility model is usually directed to a kind of common forging glof club head formed by two or more materials and this The manufacture method of the glof club head of sample.More specifically, it the utility model is related to and iron type Gao Er produced by preforming blank Husband's club head, its two or more included material before actual forging method；So as to obtain such more materials Glof club head, it for example machines without any rear manufacturing operation, welds, die forging, gluing etc..

Background technology

Golf is difficult！When the golfer of your mean levels brandishes golf clubs, he or she He or she golf brandish it is middle can have dynamic change, this generates it is many it is eccentric impact, which results in it is direct Center impact is compared to the performance reduced.But this extremely difficult game is come for the golfer of mean level Say in more pleasant trial, golf club design person comes up with the golf club design of uniqueness, it will mitigate not perfect Such cruel reality for brandishing of golf.

In the example of an early stage, the United States Patent (USP) No.4523759 of Igarashi discloses a kind of sky of periphery counterweight Heart golf iron head, its effective hitting region with foam core and towards centre of moment enrichment, to attempt to help so that height Er Fu movements are easier.It will can increase the moment of inertia of glof club head in the distribution of weight of golf clubs to circumference (MOI), golf clubs undesirable distortion when it impacts golf is reduced.

The United States Patent (USP) No.4809977 of Doran et al. is shown by the way that other weight is placed in glof club head Heel and toe, to attempt another example of the moment of inertia of increase glof club head.Match somebody with somebody Beijing South Maxpower Technology Co. Ltd by increasing heel and toe This increase for the glof club head the moment of inertia enough realized can further prevent golf clubs in heel and toe direction On distortion, it has subtracted the undesirable effect that golf is sent to target track.

Although the initial efforts for increasing the handy of the golf clubs of mean level golfer and match property are worth Appreciation, but it does not have that utilization is extremely handy, it can form glof club head not by using different materials Realized with partly.In one example, the United States Patent (USP) No.5885170 of Takeda is shown using multiple material to produce The advantages of more extreme adjusting capability and performance.More specifically, United States Patent (USP) No.5885170 teaches a kind of main body, its have by The face that a kind of material is formed, while socket is that another material for having proportion to be different from the head main body is formed.Helmstetter Et al. United States Patent (USP) No.6434811 show by provide with Weighting system glof club head, utilize multiple material To improve another example of glof club head performance, which introduced after glof club head has integrally been formed 's.

Recently, multiple material is introduced into improving by by many different materials of different qualities in glof club head Material is introduced into glof club head by machining chamber, and obvious ripe.More specifically, the United States Patent (USP) of Cole et al. No.7938739 discloses a kind of glof club head, its have with glof club head integrate chamber, wherein the chamber from Heel area extends to toe area；Extend along the lower part at the glof club head back side；It is roughly parallel to impact surface extension；And And center line (its by between heel area and toe area glof club head halve) around be substantially symmetric.

But when multiple material is introduced golf clubs after the completion of main body, the tolerance at the interface between different materials The undesirable side effect for the sensation for changing glof club head can be potentially resulted in.The United States Patent (USP) of Hettinger et al. No.6095931 is determined due to the use of a variety of different components and is sacrificed this specific undesirable side effect of sensation.The U.S. Patent No.6095931 between glof club head and main part (it includes impact proparea) by providing separation layer, to solve Determine this problem.

The United States Patent (USP) No.7828674 of Kubota have recognised the seriousness of this problem as follows：There is viscoelastic by description The hollow golf club heads of property element feel it is light and hollow for preferable golfer, therefore they are not Golf clubs as preference.United States Patent (USP) No.7828674 by introducing MAG block, be implanted into and/or/be crimped onto only In the recess that the metal sealed with metal lid is formed, and solves the defects of such more material golf clubs.

Although all the trial of above-mentioned improvement glof club head performance is all while attempt to so that golf clubs is felt Sacrifice minimize, but whole methods need it is substantial amounts of after manufacturing operation, it is formd in club head for introducing time The chamber and recess of level material.The secondary operation of these types is not only costliness, and keeps severe between different components Glof club head that the ability for the enough tolerances carved to keep usually to be formed with unitary is relevant solid to feel it is very tired Difficult.

Therefore, although from the above, it is seen that there is produce glof club head (it is more preferable to use, without sacrifice with The conventional relevant sensation of club head) in whole development, but this area is without using harsh rear manufacture machining, (it draws Risen difference sensation) when cannot produce such club.

Fig. 1 of attached drawing is shown according to a kind of the saturating of the glof club head 100 of exemplary of the utility model View.Glof club head 100 shown in Fig. 1 can generally comprise main part 102 and jack part 104, and main part Divide 102 there is several individually identifiable component such as top line parts 106, bottom 108, heel 110 and toe 112.According to this A kind of glof club head 100 of exemplary of utility model can generally comprise at least one adjustment of weight part, It is encompassed in the main part 102 of glof club head 100.In a preferred embodiment, the adjustment of weight part It can be encompassed with monoblock in main part 102, to ensure that the adjustment of weight part is fixed in main part 102, without departing from The scope of the utility model and content.Because the adjustment of weight part monoblock encompasses the main part in glof club head 100 In 102, therefore these weight are invisible in figure 1 of the accompanying drawings.But when providing different a variety of views, these weight tune Section part will be shown in more detail in the figure below.

Before subsequent figure is gone to, herein it is worth emphasizing that current glof club head 100 is to use forging side What method produced, and the weight is introduced, without the smart machine operations behind any.This is the important difference to be established, Because for example cast the identical result that extremely difficult realization encompasses with monoblock adjustment of weight part using selectable manufacture method.Make For mentioned in present patent application, " monoblock encompasses " can be generally defined as having be placed in it is specific in single external component Internal part, there is no connector or seam in final product.In the utility model, in glof club head 100 It can be commonly referred to as with " monoblock encompasses " adjustment of weight part with being placed in glof club head in main part 102 Either made without connector after the ability of the seam connector or seam are typically adjustment of weight part in main part 102 Method such as milling is made, is welded, brazing, gluing, or die forging are required.

At this it be also noted that in the current definition of the utility model, " monoblock encompasses " weight can be potential Weight inside with some aspects, it is exposed to the open air in final product to show the presence of adjustment of weight part, without departing from The scope of the utility model and content.More specifically, " monoblock encompasses " refers to the side for forming final products as described above Method, and may not need and be confined to visually hide adjustment of weight element.

Fig. 2A -2D show being used for form common forging Gao Er of a kind of exemplary according to the present utility model The method of husband's club head 200.More specifically, Fig. 2A -2D, which are shown, forges glof club head from its 201 shape of original blank Cause step included in the final products of glof club head 200.

Fig. 2A shows the preforming blank 201 according to a kind of exemplary of the utility model.In Fig. 2A As it can be seen that preforming blank 201 can start usually as the cylindrical bar formed by the first material, such as glof club head In 200 usually like that.In order to form adjustment of weight part 215, (it can encompass the main part in glof club head 200 with monoblock Divide 202), one or more chambers 216 are machined in preforming blank 201.In this exemplary reality at present shown in Fig. 2A Apply in scheme, two chambers 216 are mach in the end of preforming blank 201.Chamber in preforming blank 201 216 position and geometry are important because it directly with the adjustment of weight part in glof club head after forging 200 215 final position is related.

Turn to Fig. 2 B, it can be seen that once machining chamber 216, then be different from the first material by the density of chamber 216 Second material of density is partially filled with, forming adjustment of weight part 215.Similar to the discussion above, adjustment of weight part 215 position, size and dimension are crucial as the position of chamber 216, size and dimension, because in preforming blank 201 Adjustment of weight part 215 be relevant with the final present position of the adjustment of weight part 215 in glof club head.

Finally, Fig. 2 C are shown when remaining volume of chamber 216 is filled by the first material and by traditional associated methods Such as welding, brazing and die forging to seal when, the terminal stage of preforming blank 201.Sealed chamber 216 is so that adjustment of weight portion 215 monoblocks are divided to encompass in the main body of preforming blank 201, it will cause after forging method, identical adjustment of weight portion 215 monoblocks are divided to encompass in the main body 202 of glof club head 200.After chamber 216 is filled with, preforming blank 201 passes through Go through and the relevant normal forging method of the forging of glof club head 200.Although glof club head 200 is included in forging Basic step be important for understanding the utility model, but it includes relatively outmoded and known technology, this Application repeats no more.Included step in the basic glof club head of the adjustment of weight part encompassed on forging no monoblock Rapid more information, can be in the United States Patent (USP) No.6666779 of the United States Patent (USP) No.3825991 and Iwata of Cornell et al. In find, the disclosure of which is all incorporated by reference herein in its entirety.

Although the discussion on forging golf clubs as reference incorporated above is beneficial to the actual forging side of description Method, but it does not solve the other focus of the common forging method of the utility model, wherein being wrapped in this forging method Two kinds of different materials are included).More specifically, because adjustment of weight part 215 is by different from for forming preforming blank Second material of the first material of 201 remainder is made, it is therefore necessary to takes special attention to ensure different materials It can forge together to form glof club head 200.Therefore, in order to select two kinds of adhesion materials that can be forged altogether together, First material and the second material, which must would generally have, is related to their flow stress and their thermal coefficient of expansion very Specific material performance requirement.Although for two kinds of materials, most preferably forged with identical material property Uniformity in making, but cannot be provided using identical material and be used as the required any adjustment of weight benefit in the utility model basis Place.

First, in order to enable metal material has the ability forged altogether together, it is necessary to which with due regard to each material is each From flow stress.The flow stress of material, can be generally defined as material described in continuous deformation (i.e. so that metal keeps stream It is dynamic) needed for stress instant value；And the forging of adhesion is formed by two kinds of different materials when undergoing the stress of forging method Component will need them to be flowed with relatively the same speed.It is well known that the flow stress of material is typically the letter of yield strength Number, and the flow stress of material can usually be calculated by following formula (1).

Y_f=KeⁿEquation (1)

Wherein

Y_f=flow stress (MPa)

The K=coefficients of strain (MPa)

N=strain hardening exponents

In addition to above-mentioned formula, herein it is worth mentioning that the flow stress of material can not be analyzed in a vacuum, and It is the function of the forging temperature of it or material.Therefore in the current exemplary of the utility model, the first material It is to be substantially similar in the first flow stress of its first forging temperature, but is not equal to second forging of second material at it Make the second flow stress of temperature；And first forging temperature and the second forging temperature are substantially similar.More specifically, In more detailed embodiment, the first material can be 1025 steel, its first flowing in about 1200 DEG C of forging temperature Stress is about 10ksi (thousand pounds/square inch), and the second material can be niobium material, its forging temperature at about 1100 DEG C Second flow stress of degree is also about 12ksi.

Although in the exemplary of above-mentioned the utility model, the first material can be 1025 steel and the second material It can be niobium material；It is also possible to use different other materials, without departing from the scope of the utility model and content, as long as Their flow stress similar forging temperature be it is similar just.In other words, any two material can be used for this practicality In new common forging method, as long as the second flow stress no more than more than 20% or is not less than compared to the first flow stress Less than 20% just.

As it was previously stated, being different from flow stress, the thermal coefficient of expansion of the first material and the second material is for two kinds of different materials The suitable of material is altogether important for forging.More specifically, the first thermal coefficient of expansion of the first material, which usually may require that, is more than Or the second thermal coefficient of expansion at least equal to the second material.Because contraction of the thermal coefficient of expansion also with material after forging has Close, it is therefore important that the first material thermal coefficient of expansion of (its monoblock encompasses the second material) with higher is prevented in the material The interface portion office of material forms gap.In a kind of more detailed embodiment of the utility model, the first material can be 1025 steel, its thermal coefficient of expansion is about 8.0 μ in/in °F, and the second material can be niobium, its second thermal coefficient of expansion is big About 3.94 μ in/in °F.

Although it should be noted that in above-mentioned example embodiment, the second thermal coefficient of expansion is less than the first thermal expansion system Number, but the numeral can realize that two kinds of materials perfectly match with identical, without departing from the scope of the utility model and interior Hold.In fact, in a kind of exemplary of the utility model, it may be preferable that the first material and the second material tool There is identical thermal coefficient of expansion, because the contraction of the outer excessive material on interior material can dive in the interface portion office of two kinds of materials The other stress of generation.

Selectable, in the trial for providing different weighting charateristics, the second material can be made of 6-4 titanium material to drop Low weight adjusts the weight of part 215.The titanium material can be big in about 1100 DEG C of the common flow stress of forging temperature About 10ksi and thermal coefficient of expansion are about 6.1 μ in/in °F.

It now been discussed the specific concern of the forging method and the common forging including different materials, Fig. 2 D of attached drawing Show the perspective view using the above-mentioned glof club head 200 for the completion that forging method produces altogether, wherein glof club head 200 in main part 202 monoblock encompass at least one adjustment of weight part 215.More specifically, it is current in the utility model In exemplary, adjustment of weight part 215 is placed near the heel 210 and toe 212 of glof club head 200. Adjustment of weight part 215 is placed in heel 210 and toe 212 nearby so that glof club head 200 has increased the moment of inertia (MOI), without any secondary attended operation；More consistent sensation will be produced in golf impact.

Before going to and being related to the discussion of the different embodiment of the utility model, herein it is worth noting that adjustment of weight Exact position of the part 215 in the main part 202 of glof club head 200 is slightly in each single different club head Have different, this is that the common forging method of the utility model includes the result of different materials.More specifically, adjustment of weight part 215 exact position can be different in each single golf clubs 200, because first material and the second material Flow stress will assist in the final position of adjustment of weight part 215.In addition to that mentioned above, it shall be noted that be adjustment of weight Interface between part 215 and the main part 202 of glof club head 200 usually can be irregular interface, have sawtooth Shape border represents that whole glof club head 200 forges altogether.This machines secondary operation such as milling after differing markedly from Chamber caused by cutting and drilling；It usually has the clear Y-track of two kinds of different materials.

Fig. 3 A-3D of attached drawing show a kind of selectable embodiment of the utility model of knowing clearly, wherein by two difference Adjustment of weight part 314 and 315 be placed at the different piece of preforming blank 301, to be formed with different performance standards Glof club head 300.More specifically, the glof club head 300 shown in Fig. 3 D can have in glof club head 300 Top line part 306 near lightweight adjustment of weight part 314 and near the bottom 308 of glof club head 300 The adjustment of weight part 315 of heavyweight, to help the center of gravity (CG) by glof club head 300 to move down, to help this practicality new The transmitting of the glof club head 300 of type and revolving property.

Similar to above, Fig. 3 A-3C show the forming method of the glof club head 300 of the utility model, it is by pre- Shaping blank 301 starts.More specifically, Fig. 3 A are shown according to a kind of preform of exemplary of the utility model The perspective view of material 301, wherein having drilled multiple chambers 316 on the strategic location of blank 301.It should be noted that in this mesh In preceding exemplary, multiple chambers 316 are drilled in the top section and base section of preforming blank 301, generation For in each end, because this specific embodiment focuses on the CG as got off to reduce glof club head 300：From Gao Er Weight is removed in 306 part of top line of husband's club head 300 and moves its base section 308 towards glof club head 300 It is dynamic.

Fig. 3 B of attached drawing show that two adjustment of weight parts 314 and 315 are placed in caused by Fig. 3 A in chamber 316. Although usually it is desirable that can cause that the weight of the near top of glof club head 300 is minimum when it is expected and reducing CG Change, but in this current embodiment of the utility model, top chamber 316 cannot completely vacant placement because entirely Preforming blank 301 will finally be forged into the shape of glof club head 300, this causes any plenum chamber 316 to cave in itself.Cause In this exemplary at present of the utility model, top chamber 316 can use the adjustment of weight part of light weight for this 314 fill, and lower chamber 316 can fill with the adjustment of weight part 315 of weight.The adjustment of weight part of the light weight 314 can usually be made of the 3rd material with triple density, wherein the adjustment of weight part 315 of the weight can usually by The second material with the second density is made.In a kind of exemplary of the utility model, which can be with Generally less than about 7.0g/cc, wherein second density can be typically larger than about 7.8g/cc；And it is used to form golf First material of the main part 302 of head 300 can usually have the first density of about 7.8g/cc.

Fig. 3 C of attached drawing show the terminal stage of preforming blank 301, and monoblock is encompassed in preforming blank 301 for it Internal chamber 316 in adjustment of weight part 314 and 315 in.More specifically, forming the preforming blank shown in Fig. 3 C includes With remaining volume of the first material filled chamber 316, adjustment of weight part 315 and 316 is encompassed in preforming blank 301 It is interior.Similar to discussed above, then forging forms the glof club head 300 shown in Fig. 3 D to preforming blank 301, wherein heavy Amount adjusts 314 and 315 monoblock of part and encompasses in the main part 302 of glof club head 300.

Similar to the above method, the 3rd material forges altogether in the chamber that the first material is formed, and the 3rd material would generally Need that there is the 3rd flow stress, it is similar to the first flow stress of the first material, and first with less than the first material 3rd thermal coefficient of expansion of thermal coefficient of expansion.More specifically, in a kind of exemplary of the utility model, the 3rd Material can be 6-4 titanium material, its 3rd flow stress and about 6.1 in about 1100 DEG C of forging temperature about 10ksi The 3rd thermal coefficient of expansion of μ in/in °F.

Although Fig. 2A -2D and Fig. 3 A-3D, which are respectively illustrated, is used for realization the utility model of higher MOI and relatively low CG not Same embodiment, but these features are not mutually exclusive.In fact, in the another of the utility model shown in Fig. 4 A-4D In one selectable embodiment, feature can be derived from above two embodiment has higher MOI and relatively low CG to be formed Common forging glof club head, all without departure from the scope of the utility model and content.More specifically, in Fig. 4 A-4D, The step is needed the adjustment of weight part 414 of lightweight introducing the top section 406 of golf clubs 400 nearby and incited somebody to action The toe 412 and heel 410 of the introducing of adjustment of weight part 415 glof club head 400 of the heavyweight of two or more are attached Closely, come formed have higher MOI and relatively low CG golf clubs.

Fig. 5 A-5D of attached drawing show another selectable embodiment of the utility model, wherein glof club head 500 main part 502 can include the adjustment of weight part 514 that monoblock encompasses.In this current example of the utility model In property embodiment, adjustment of weight part 514 can be that size is relatively large, this causes it to instead of when forging method is completed The most main part 502 of glof club head 500.In this exemplary at present of the utility model, The adjustment of weight part 514 that the monoblock encompasses can usually be made of the 3rd material with triple density, and the triple density is bright First density of aobvious the first material for being less than the main part 502 for being used to be formed glof club head 500；This allows from golf Weight is taken down in the main part 502 of club head 500.Because the 3rd material of the light weight for forming adjustment of weight part 514 Would generally than the first material flexible relative, therefore usually it is desirable that encompassing 514 monoblock of adjustment of weight part in Gao Er In the inside subject of husband's club head 500, this can realize obvious weight savings, feel without sacrificing.

More specifically, Fig. 5 A of attached drawing show the preforming blank 501 similar to first figure.But in this mesh In preceding exemplary, the chamber 506 in preforming blank 501 itself is significantly greater.This big chamber 506 therefore can For in Fig. 5 B, the weight, density and associative perception of glof club head 500 are adjusted to be filled with adjustment of weight part 514 Feel.In figure 5 c, similar to above-mentioned, forging method is undergone in whole preforming blank 501 to form glof club head 500 Before, remaining volume of chamber 516 is filled with the first initial material.

At this it is worth noting that in this exemplary at present, the jack part of glof club head 500 504 are made of the first conventional material, because the flexural property of the second material for forming adjustment of weight part 514 would generally It is unsuitable for the bending requirement of iron type golf club head 500.More specifically, for forming the 3rd of adjustment of weight part 514 Material can be iron-aluminum of light weight, its density is less than about 7.10g/cc, more preferably less than about 7.05g/cc and optimal Choosing is less than about 7.00g/cc, all without departure from the scope of the utility model and content.But many other materials also may be used Using as the 3rd material, for forming adjustment of weight part 514, without departing from the scope of the utility model and content, as long as The density of three materials is within the above range just.
