Technical field

The utility model relates generally to a kind of common forging glof club head formed by two or more materials and system The method for making such glof club head.Swage golf is created by preforming blank more specifically, the utility model is related to Club head, the preforming blank contain two or more materials before actual forging technology；Result is that manufacture is more The glof club head of kind material, it is not necessary to any subsequent fabrication operations, machining, welding, swaged forging, bonding etc..

Background technology

Golf is difficult！When common horizontal linksman brandishes golf clubs, he or she is brandishing Unexpected change occurs during golf clubs, this causes many off-center hits, and it causes compared with direct center hits Cause the reduction of achievement.But, it is intended to common horizontal linksman is more enjoyed this very difficult motion, Gao Er Husband's club designer employs the golf club design of uniqueness, and it can mitigate the harsh of less perfect golf and show It is real.

In the embodiment of an early stage, Igarashi United States Patent (USP) No.4,523,759 disclose a kind of perimeter weighting Hollow Golf club iron, it has foam core, the foam core have to centre of moment concentrate effective hitting region, it is intended to help Helping is easier golf sports.The moment of inertia that the distribution of weight of golf clubs to periphery is allowed to make glof club head (MOI) increase, reduce the undesirable torsion of the golf clubs when golf clubs hits golf.

Doran et al. United States Patent (USP) No.4,809,977 show another embodiment, and it is attempted by golf Additional weight is placed to increase the moment of inertia of glof club head in the heel part of club head and toe office.By increase with The increase of the moment of inertia of part and the achievable glof club head of toe portion counterweight can further prevent golf clubs Reversed in heel part and toe portion direction, which reduce the adverse consequences for deviateing expected orbit launching golf.

Although the preliminary trial for the pardon and playability for increasing golf clubs for common horizontal linksman is It is laudable, but it obtains the bag of extreme not over using different materials to form the different piece of glof club head Capacitive.In one embodiment, Takeda United States Patent (USP) No.5,885,170 show using multiple material to create confrontation Measure the advantages of more extremely adjustment of attribute.More specifically, United States Patent (USP) No.5,885,170 teach a kind of main body, main body tool There is the face being formed of one material, while hosel is formed by another material, another material has the material with head main body Expect different proportion.Helmstetter et al. United States Patent (USP) No.6,434,811 show it is another using multiple material come The embodiment of glof club head performance is improved, it is realized by setting Weighting system on glof club head, described to match somebody with somebody Weight system is combined after whole glof club head is formed.

Recently, it is significantly ripe that multiple material is attached to the improvement of glof club head, will be permitted by being machined chamber The multiple material of more different qualities is attached in glof club head.More specifically, Cole et al. United States Patent (USP) No.7,938, 739 disclose a kind of glof club head for the chamber for having and being integrated with glof club head, and the wherein chamber extends to from region Toe region；Extend along the bottom at the back side of glof club head；It is roughly parallel to impact surface extension；And on region The center line for traversing glof club head between toe region is substantially symmetric.

However, because main body completed after just multiple material is incorporated into golf clubs, different materials it Between interface tolerance may potentially result in change glof club head sensation undesirable side effect.Hettinger Et al. United States Patent (USP) No.6,095,931 to confirm to sacrifice feel this by using a variety of different parts specific not Good side effect.United States Patent (USP) No.6,095,931 is by between glof club head and the main part including impact front waist section Separation layer is provided to solve this problem.

Kubota United States Patent (USP) No.7828674 recognizes the seriousness of this problem, and it is claimed with visco-elastic element Hollow golf club head allows more preferable linksman to feel lighter and hollow, therefore they show no favouritism to such golf Club.United States Patent (USP) No.7828674 only uses metal cap close in a metal by that will wait to be embedded into and/or wait to be pressed into be formed MAG block in the recess of envelope is insufficient to solve such multiple material golf clubs.

Although improve the whole of the performance of glof club head above to attempt all while attempt to making the sensation of golf clubs Sacrifice minimize, but all methods describeds are required for creating chamber and recess in club head to be combined auxiliary material A large amount of subsequent fabrication operations.The auxiliary operation of these types is not only costliness, and remains tight enough between a variety of parts The ability of tolerance to be very difficult to keep solid sensation typically associated with the glof club head being unitarily formed.

Therefore, more than it can be seen that, although all exploitation be all do not sacrifice it is related to conventional golf club head The glof club head with bigger pardon is created in the case of the sensation of connection, but current area can not be led not utilizing Such golf clubs is created in the case of causing the follow-up manufacture of harshness of poor sensation to be machined.

Embodiment

Described in detail below is to implement current optimal desired pattern of the present utility model.The description should not be in restrictive, sense To understand, but only it is shown merely for illustrating that the mesh of General Principle of the present utility model is made, because model of the present utility model Enclose and most preferably limited by appended claims.

Each of various features described below can be used independently of each other or are used in combination with other features.So And any single feature may not solve any one problem or all problems as discussed above, or may address only A problem in the problem of text discusses.In addition, one or more of problems discussed above may be completely under Any one solution in feature described by text.

Fig. 1 in accompanying drawing is shown according to the glof club head 100 of an exemplary of the present utility model Perspective view.Figure 1 illustrates glof club head 100 generally include main part 102 and hosel part 104, wherein main body Portion 102 has several parts being individually identified, such as lineback part 106, base part 108, heel part 110 and toe portion 112.Generally included to load golf clubs according to the glof club head 100 of an exemplary of the present utility model At least one weight adjustment member in first 100 main part 102.In a preferred embodiment, the weight is adjusted Whole point integratedly can be loaded in main part 102, to ensure in the feelings without departing from the scope of the utility model and content The weight adjustment member is fixed in main part 102 under shape.Because the weight adjustment member is integratedly loaded high It is invisible in the described Fig. 1 of these weight adjustment members in the accompanying drawings in the main part 102 of golf ball head 100.However, When a variety of different views are presented, these weight adjustment members will be illustrated in greater detail in figure later.

Before being moved on subsequent figure, it is worth it is noted that current glof club head 100 is using forging Make that technique creates and do not need any subsequent fine machining operations with reference to the weight.This will establish an important area Not, because being extremely hard to realize the identical knot of integratedly loading weight adjustment member using manufacturing process (such as casting) is substituted Fruit.Alleged " integratedly loading ", which is generally defined as having, such as in current patent application is placed on single external component Internal specific internal part and there is no joint or seam in the product of completion.As for the utility model, have " integratedly Weight adjustment member of the loading " in the main part 102 of glof club head 100, which can typically refer to, is not manufacturing work subsequently Have in the case of the commonly required joint of skill (milling, welding, soldering, bonding or swaged forging etc.) or seam in golf The ability for the weight adjustment member that the inside of main part 102 of head 100 is placed.

It is also noted herein that in the case of the scope of the utility model and content is not departed from, work as of the present utility model The weight of " being integratedly fitted into " in preceding definition can potentially have some of exposed weight inside in the product of completion Aspect, to show the presence of weight adjustment member.More specifically, " integratedly loading " refers to being used to create as described above Final products method, and may be not necessarily limited to visually hide weight adjustment member.

Fig. 2A-Fig. 2 D are shown for creating the common forging golf according to an exemplary of the present utility model The method of club head 200.More specifically, Fig. 2A-Fig. 2 D are shown is forged into height in glof club head from its basic blank 201 Involved step in the final product of golf ball head 200.

Fig. 2A shows the preforming blank 201 according to an exemplary of the present utility model.Such as from Fig. 2A It can be seen that, preforming blank 201 can typically start the cylindrical bar to be formed by the first material, because it is for Gao Er The forging of husband's club head 200 is common.In order to create the main part 202 that can integratedly load glof club head 200 Interior weight adjustment member 215, one or more chambers 216 are processed in the preforming internal mechanical of blank 201.Show in fig. 2 This current exemplary in, two chambers 216 are machined into the end of preforming blank 201.Preform The position of chamber 216 in material 201 and geometry are important, because it directly exists with weight adjustment member 215 after forging Final position association in glof club head 200.

It is moved on Fig. 2 B, it can be seen that once chamber 216 is machined into, with regard to the second material part filled cavity 216, second material has the density different from the density of first material, to create weight adjustment member 215.It is similar In discussion above, the position of weight adjustment member 215, size, position, the size and shape no less important of shape and chamber 216, Because weight adjustment member 215 and most final position of the weight adjustment member 215 in glof club head in preforming blank 201 Put association.

Finally, Fig. 2 C are shown when the residual volume of chamber 216 is filled with the first material and passes through Conventional attachment methods The final stage of preforming blank 201 during (such as welding, soldering and swaged forging) sealing.Annular seal space 216 allows weight adjustment member 215 are integratedly loaded in the main body of preforming blank 201, and this will allow identical weight adjustment portion after forging technology 215 are divided integratedly to load in the main body 202 of glof club head 200.After chamber 216 is filled, pass through preforming blank 201 By the conventional wrought processes associated with the forging of glof club head 200.It is although involved in glof club head 200 is forged And basic step for understanding that the utility model is important, but it is related to technology that is relatively outmoded and having established, this Application will be no longer to this too many details of input.On in no basic golf clubs for integratedly loading weight adjustment member The more information of involved step can be in Cornell United States Patent (USP) No.6,666,779 and Iwata etc. in the forging of head The United States Patent (USP) No.6 of people, find in 666,779, the Disclosure of U.S. patent, which all passes through to quote, overall combines this Text.

Although the described above of the forging on golf clubs being incorporated by reference can describe actual forging well Technique, but it fails solve the additional of the forging process altogether of the present utility model for being related to two kinds of different materials in this forging technology Concerned issue.More specifically, because weight adjustment member 215 is by can be with the remainder for creating preforming blank 201 Different the second material of the first material be made, it is therefore necessary to pay special attention to ensure that the different materials can be forged one Rise to form glof club head 200.Therefore, in order to select can forging two kinds of coherency materials together altogether, the first material Must typically have the very specific material related to their flow stress and their thermal coefficient of expansion to the second material Attribute specification.Although most preferably described two materials is keep forging uniformity to have identical material property, It cannot provide basis of the present utility model required any adjustment of weight benefit using identical material.

First, ability together is forged, it is necessary to account properly for every in the material altogether in order to which metal material has The respective flow stress of kind material.The flow stress of material can typically be defined as making material continuous modification (keep metal Flowing) needed for stress instantaneous value；And forming coherency forged part by two kinds of different materials will need in the material Them are subjected to during the stress of forging technology to flow with relatively the same speed.It is generally known that the flow stress of material is general It is the function of bending strength, the flow stress of material can typically be summarized as below equation (1)

Y_f=KeⁿFormula (1)

Wherein

Y_f=flow stress (MPa)

The K=coefficients of strain (MPa)

N=strain hardening exponents

Except above formula, it is that the flow stress of material can not be explained in vacuum, phase referred in this to be worth Instead, it is equally the function of the forging temperature of material.Therefore, in a present exemplary embodiment of the present utility model, First flow stress of first material under its first forging temperature be substantially similar to but unlike that the second material its The second flow stress under two forging temperatures；Wherein described first forging temperature and second forging temperature are generally classes As.More specifically, in a more detailed embodiment, first material can be the forging temperature at about 1200 DEG C 1025 steel of lower the first flow stress with about 10ksi (thousand pounds/square inch) of degree, and second material can be The niobium material of the second flow stress with about 12ksi under 1100 DEG C of forging temperature.

Although in exemplary of the present utility model as described above, first material can be 1025 Steel and second material can be niobium material, but can also in the case of the scope of the utility model and content is not departed from Using various other materials, as long as their flow stress is similar under similar forging temperature.In other words, it is as long as described Second flow stress is not higher than or 20% not less than first flow stress, then any two material may be incorporated for In current common forging process.

As previously mentioned, in addition to flow stress, the thermal coefficient of expansion of the first material and the second material is for two kinds The appropriate forging altogether of different materials is also important.More specifically, the first thermal coefficient of expansion of the first material may typically need greatly In or equal to the second material the second thermal coefficient of expansion.Because thermal coefficient of expansion is also relevant with the contraction of material after forging, It is important that there is the first material for integratedly loading the second material higher thermal coefficient of expansion to prevent on the boundary of the material Facial office forms gap.In one of the present utility model more detailed embodiment, the first material can be had about 1025 steel of 8.0 μ in/in °F the first thermal coefficient of expansion, and the second material can be with about 3.94 μ in/in °F the The niobium of two thermal coefficient of expansions.

It should be noted that although the second thermal coefficient of expansion described in foregoing exemplary embodiment is less than first thermal expansion Coefficient, but in the case of the scope of the utility model and content is not departed from, the numeral can be identical to realize State the perfect matching between two kinds of materials.In fact, in an exemplary of the present utility model, can be preferable It is that the first material and the second material have identical thermal coefficient of expansion, because internally excessive shrink can on material for exterior material Potentially to produce additional stress in the interface portion office of described two materials.

Alternatively, attempt to provide different weight characteristics, the second material can be made up of 6-4 titanium material to reduce weight tune Whole point 215 of weight.The titanium material can typically have about 10ksi flowing under about 1100 DEG C of forging temperature The thermal coefficient of expansion of stress and about 6.1 μ in/in °F.

Now, forging technology has been discussed and has been related to the special attention problem of the common forging of different materials, in accompanying drawing Fig. 2 D show the perspective view of glof club head 200 of the more than use completion that common forging process creates, the wherein golf clubs First 200 integratedly load at least one weight adjustment member 215 in main part 202.More specifically, of the present utility model In present exemplary embodiment, weight adjustment member 215 is placed on the heel part 210 and toe of glof club head 200 Divide near 212.Weight adjustment member 215 is placed around allowing glof club head 200 to exist in heel part 210 and toe portion 212 There is increased moment of inertia (MOI) in the case of not needing any auxiliary attachment operation；This will be when with golf ball Produce more consistent sensation.

It is noticeable herein before carrying out being related to discussion the utility model of the utility model different embodiments example It is that weight adjustment member 215 is placed exactly in each single difference in the main part 202 of glof club head 200 Club head in it is slightly different, this is the achievement for the common technique of the utility model for being related to different materials.More specifically, weight is adjusted Whole point 215 of accurate placement can be different with each single glof club head 200, because first material and described The flow stress of second material will be helpful to determine the final position of weight adjustment member 215.In addition to above, it should be noted that Interface between the weight adjustment member 215 and main part 202 of glof club head 200 typically can be irregular interface, With uneven border to show that whole glof club head 200 is forged altogether.This is markedly different from via follow-up machine The chamber that tool processing auxiliary operation (such as milling and drilling) creates；Subsequent mechanical processing auxiliary operation typically has two kinds of differences The clear Y-track of material.

Scheme attached Fig. 3 A- Fig. 3 D and show an alternate embodiment of the present utility model, the single weight of two of which Adjustment member 314 and 315 is placed at the diverse location of preforming blank 301, to create the height with different performance standard Golf ball head 300.More specifically, the glof club head 300 shown in Fig. 3 D can be in the top line of glof club head 300 Part 306 is nearby with weight with lightweight weight adjustment member 314 and near the substrate 308 of glof club head 300 Level weight adjustment member 315, to help to make center (CG) skew of glof club head 300 lower, to contribute to this practicality new The service characteristic and revolving property of the glof club head 300 of type.

With above similar, Fig. 3 A- Fig. 3 C show the forming process of glof club head 300 of the present utility model, the shape Into process since preforming blank 301.More specifically, Fig. 3 A are shown according to an exemplary embodiment party of the present utility model The perspective view of the preforming blank 301 of case, wherein drilling out multiple chambers 316 at key position in blank 301.It should be noted that It is, in this current exemplary, at the top of preforming blank 301 and bottom point nearby rather than every Individual end drills out multiple chambers 316 because this specific embodiment focus on by by weight from the top of glof club head 300 Line part 306 is removed to reduce the center of gravity of glof club head 300 and make center of gravity towards the basal part of glof club head 300 Divide 308 skews.

Fig. 3 B of accompanying drawing show two recanalization parts 314 and 315 inside the chamber 316 placed and created in figure 3 a. Although when expectation lowers the center of gravity CG, the weight near top that may be it typically would be desirable to make glof club head 300 minimizes, But it can not be complete empty that chamber 316 is pushed up in current embodiment of the present utility model, because whole preforming blank 301 will The final shape for being forged into glof club head 300, this can cause any empty chamber 316 itself to collapse.Therefore, in this practicality In this new present exemplary embodiment, the filling of lightweight weight adjustment member 314 top chamber 316 can be used, and can be used Heavyweight weight adjustment member 315 fills cavity of resorption 316.Lightweight weight adjustment member 314 typically can be by with triple density The 3rd material be made, its middle heavyweight weight adjustment member 315 can typically be made up of the second material with the second density. In an exemplary of the present utility model, the triple density may be generally less than about 7.0g/cc, wherein institute About 7.8g/cc can be typically more than by stating the second density；And it is used for the of main part 302 to form glof club head 300 One material can typically have about 7.8g/cc the first density.

Fig. 3 C of accompanying drawing show the terminal stage of preforming blank 301, and the preforming blank 301 has had integratedly The weight adjustment member 314 and 315 loaded in the inner chamber 316 of preforming blank 301.More specifically, what is shown in Fig. 3 C is pre- The establishment of shaping blank, which is related in the residual volume of chamber 316, fills the first material, and weight adjustment member 315 and 316 is filled Enter in preforming blank 301.Similar to described above, the preforming blank 301 is then forged what is shown to create in Fig. 3 D Glof club head 300, wherein weight adjustment member 314 and 315 are integratedly loaded the main part of glof club head 300 In 302.

Similar to method as described above, the intracavitary formed in the first material forges the 3rd material, the 3rd material altogether It may typically need with threeth flow stress similar with the first flow stress of the first material and less than the first material 3rd thermal coefficient of expansion of the first thermal coefficient of expansion.More specifically, in an exemplary of the present utility model, institute It can be 6-4 titanium material to state the 3rd material, and the 6-4 titaniums material has about 10ksi under about 1100 DEG C of forging temperature The 3rd flow stress, and with about 6.1 μ in/in °F the 3rd thermal coefficient of expansion.

Of the present utility model it is respectively used to realize higher MOI and relatively low CG although Fig. 2A-Fig. 2 D and Fig. 3 A- Fig. 3 D are shown Different embodiments, but these features are not repelled each other.In fact, this practicality shown in Fig. 4 A- Fig. 4 D In another new alternate embodiment, feature can be derived from two embodiments discussed above, to create with higher The glof club head of MOI and relatively low CG common forging, all without departing from the scope of the utility model and content.More specifically, Shown in Fig. 4 A- Fig. 4 D and lightweight weight adjustment member 414 is combined near the top 406 in Gao Er club heads 400, even With combining two or more heavyweight weight adjustment members near the toe portion 412 of glof club head 400 and heel 410 415 step needed for golf clubs of the establishment with higher MOI and relatively low CG.

Fig. 5 A- Fig. 5 D of accompanying drawing show another alternate embodiment of the utility model, wherein glof club head 500 Main part 502 can include the weight adjustment member 514 that integratedly loads.It is real in this present exemplary of the present utility model To apply in scheme, weight adjustment member 514 can have relatively large size, once forging technology is completed, it is allowed to and the weight adjusts Part replaces the major part of the main part 502 of glof club head 500.It is real in this current Alternative exemplary of the present utility model Apply in scheme, the weight adjustment member 514 integratedly loaded can typically be made up of the 3rd material with triple density, described Triple density is substantially less than the first density of the first material of the main part 502 for being used to be formed glof club head 500；Allow Weight is taken out from the main part 502 of glof club head 500.Because the lightweight for forming weight adjustment member 514 3rd material is general relatively soft compared with the first material, so it typically would be desirable to weight adjustment member 514 is integratedly loaded to height In the inside subject of golf ball head 500, this allows the notable mitigation that weight is realized in the case of sensation is not sacrificed.

More specifically, Fig. 5 A of accompanying drawing are similar to previous figure, preforming blank 501 is shown.However, currently show herein In example property embodiment, the chamber 506 in preforming blank 501 itself is significantly larger.Then can be big using this in figure 5b Chamber 506 carrys out filling weight adjustment member 514 to adjust the weight of glof club head 500, density and common sensation.In Fig. 5 C In, similar to described above, the residual volume of chamber 516 is filled with the first original material, afterwards whole preforming blank 501 are subjected to forging technology to create glof club head 500.

It is to be noted here that in this present exemplary embodiment, the hosel part of glof club head 500 504 are specially made of the first material of routine, because the flexural property one of the second material for forming weight adjustment member 514 As may be not suitable for the bending requirement of iron golf club head 500.More specifically, for forming weight adjustment member 514 3rd material can be with close less than 7.10g/cc, even more preferably less than 7.05g/cc and more preferably less than 7.00g/cc The lightweight iron aluminum of degree, all without departing from the scope of the utility model and content.It is however, of the present utility model not departing from In the case of scope and content, many other materials can also be used as the 3rd material for forming weight adjustment member 514 Material, as long as the 3rd material has the density in scope described above.

Fig. 6 of accompanying drawing is shown utilizes the common forging process of multi-step according to another alternate embodiment of the present utility model Glof club head 600 exploded rear perspective view.This multi-step described in Fig. 8-Figure 14 is then total to the details of forging process, Forging process allows improvement to be placed exactly in different weight component in the different piece of glof club head 600 to this multi-step altogether Ability.This improvement of the accurate ability for placing weighted is not only that allow together to provide the forging of a variety of different materials can Can-due to the intrinsic material limitation of different materials, therefore be previously impossible together by the forging of a variety of different materials, and And also allow the performance characteristics of golf clubs 600 than previously having bigger improvement.

More specifically, Fig. 6 of accompanying drawing is shown using the multi-step common forging glof club head 600 that forging process creates altogether. Glof club head 600 has corresponding to the corresponding of them at the heel part 610 and toe portion 612 of glof club head 600 Chamber 616 greater density weight adjustment member 615.Then weight adjustment member 615 is combined with common forging process with lid 617 Period makes weight adjustment member 615 and the main body of glof club head 600 keep together.It should be noted that present exemplary Gao Er Husband's club head 600 installs the weight adjustment member 615 of weight using the common forging process of multi-step, is manufactured without subsequent fine, all Such as welding, soldering, swaged forging.As previously mentioned, using it is such altogether forging process benefit be material uniformity with it is consistent Property, this brings superior performance and sensation.It is of the present utility model current however, in addition to the removal clearly expressed above Embodiment allows the end that the adjustment of weight part 615 of weight is placed on to glof club head 600, This further improves The position of centre of gravity and moment of inertia of glof club head 600.

Fig. 7 of accompanying drawing is shown according to the glof club head 700 of another alternate embodiment of the present utility model Exploded front perspective view.More specifically, in multi-step altogether forging process, glof club head 700 is hit glof club head 700 Beat and combine lightweight weight adjustment member 714 behind the part of face 718 in chamber 716.In this present exemplary of the present utility model Property embodiment in, due to accurately forging process altogether discussed above, therefore can more accurately arrange lightweight weight adjustment portion Divide 714 position and layout, therefore create the chance of the weight for the part of impact surface 718 for reducing glof club head 700.For Understanding current multi-step forging process altogether, it is involved in this multi-step altogether forging process to be described in detail following present Fig. 8-Figure 14 Step.

Similar to figure 2 above-Fig. 5, Fig. 8 of accompanying drawing shows the preforming blank for creating forging glof club head 801.This forging blank 801 is then bent to L-shaped as shown in Figure 9, so that blank 901 prepares to be used to start the forging The mould of technique.Figure 10 A and Figure 10 B show the glof club head for the first step for being already subjected to the common forging process of multi-step 1000 front view and rearview.In this earlier step, the blank has been forged into and glof club head 1000 The substantially similar shape of shape.In fact, even if in this early stage, it can also be seen that the shape of glof club head 1000, Because it has hosel part 1004, heel part 1010 and toe portion 1012.The glof club head shown in Figure 10 A In 1000 rearview, the first of chamber 1016 has been can see in the heel part 1010 and toe portion 1012 of glof club head Vestige is walked, and can be seen in the front view of the glof club head 1000 shown in fig. 1 ob near impact surface Chamber 1016.

After initially forging step, excessive trimming 1030 can remove from glof club head 1000, and after this Another rough forging step is subjected to afterwards.During the forging technology, excessive material can flow to the outer of the boundary of mould Portion, this causes commonly called " overlap ".This overlap material as previously discussed can be trimmed between each more forging steps Material, to improve the adhesion in later step to mould.

The result of this auxiliary forging step can be illustrated in Figure 11 A and Figure 11 B.Such as since Figure 11 A and Figure 11 B Arrive, the glof club head 1100 under current state starts to present and the closer shape of final products.Except more limited Outside fixed overall shape, the border of chamber 1116 and shape also begin to that their own shape is presented.After this auxiliary forging step Afterwards, weight adjustment member can be added in specific chamber 1116, and glof club head 1100 is subjected to finally forging afterwards Step.

The weight adjustment for the chamber 1116 that can be shown more clearly that in figs. 12 a and 12b on glof club head 1100 Relation between part.Here, in figs. 12 a and 12b, it can be seen that on the rear part of glof club head 1200 Chamber 1216 can be filled with weight adjustment member 1215, and the weight adjustment member 1215 can typically have than golf clubs The higher density of first 1200 main body.Then can be with made of the material similar with the main body of glof club head 1200 The upper high density weight adjustment member 1215 of the covering of lid 1217, this allows high density weight adjustment member 1215 being maintained at chamber 1216 It is interior.Before glof club head 1200, chamber 1216 can be filled with the main part with than glof club head 1200 Divide the weight adjustment member 1214 of lower density.Similar to below, this weight adjustment member 1214 can be consolidated with lid mechanism It is scheduled in chamber 1216, the lid mechanism also serves as impact surface 1218.Similar to lid 1217, impact surface 1218 can by with golf The material that the main body of club head 1200 is similar is made.Make lid 1217 and impact surface 1218 by the main body with glof club head 1200 Remainder identical material to be made be favourable because it allows both parts being welded to glof club head 1200 Main part.These parts is welded to appropriate position allows to walk in the final forging for completing the common forging process of current multi-step Weight adjustment member 1215 is fixed in the corresponding chamber 1216 of themselves before rapid.

In an alternate embodiment of the present utility model, even the He of chamber 1216 can need not be completely covered in lid 1217 Weight adjustment member 1214.In fact, in an alternate embodiment of the present utility model, lid 1217 only needs part to cover Weight adjustment member 1215 is to being enough the degree for preventing that weight adjustment member 1215 from separating with the main body of glof club head 1200.

The final forging technology being related in this process, which generally creates, is considered " forging altogether " glof club head 1200, because present glof club head 1200 contains two or more differences being forged in this final step together Material.Figure 13 A and Figure 13 B show result of the glof club head 1300 after the final step of forging altogether of its completion.It is current at its Under state, its presented net shape of glof club head 1300, and weight adjustment member 1316 and 1314 is present all Their own intracavitary is integratedly loaded by lid 1317 and impact panel 1318.Although glof club head 1300 can be taken Their form, there are still excessive overlap 1330, the excessive overlap around the periphery of glof club head 1300 1330 need glof club head 1300 after being trimmed to about that its net shape is presented.

Figure 14 A and 14B show result of the glof club head 1400 of completion as this common forging process.Here, scheming It can be seen that, excessive overlap 1330 has been trimmed to about, and improves the aesthetic feeling of glof club head 1400 in 14A and Figure 14 B.Such as It is previously mentioned, the result of forging process is total to as this, weight adjustment member 1416 and 1418 passes through lid 1417 and impact panel 1318 seamlessly and integratedly load the main body of glof club head 1400.As previously discussed, being total to forging process by this makes weight The advantages of measuring adjustment member 1416 seamlessly and integratedly loading the main body of glof club head 1400 is to prevent from sending quack sound, And improve the solid sensation of glof club head 1400.In fact, using this technique, current glof club head can be with Realize the hardly recognizable sensation of glof club head with the single forging using conventional forging method.

Or it may also be said that multi-step forges the chamber that method is located in weight adjustment member 1416 and 1418 with it altogether at present The relation of uniqueness is created between 1216 (see Figure 12).More specifically, it may be said that the exterior surface area of weight adjustment member 1416 Typically can be identical with the inner surface area of chamber 1216.Chamber 1216 can typically include being used to complete to create by rough forging step Any lid 1217 of chamber 1216 or the surface area of panel 1218.(referring to Figure 12) is although chamber 1216 and weight adjustment member Symmetric shape and surface area between 1416 may be not as innovation achievement, and real situation is, unless it is related to common forging step, Otherwise such seamless interface between the two elements is impossible.In view of the difference for glof club head Partial material bonding constraint, the common forging method currently innovated be between these components realize as seamless interface only One method.

Figure 15 of accompanying drawing shows the previously described forging altogether of utilization according to an alternate embodiment of the present utility model The front view of the product glof club head 1500 of the completion of technology.In this embodiment, striking face insert 1518 only may be used Partly to cover the lower part of glof club head 1500, this permission only creates in the lower part of glof club head 1500 Chamber.This specific bifurcated of club head 1500 can be beneficial to the property that glof club head 1500 is improved in two-chamber design is created Can, the two-chamber design has been provided about structural support in the center hemisphere of club head 1500, more solid to be provided when hitting Sensation.

Figure 16 of accompanying drawing shows the glof club head without striking face insert 1518 (showing in fig.15) 1600 front view.This view of glof club head 1600 allows to be shown more clearly that inside face chamber 1616, and showing can be with For further providing multiple support bars 1630 of structural support for striking face portion.In one embodiment, multiple bars 1630 can be the circular pin for the whole inwall for being dispersed in face chamber 1616 as shown in Figure 16.However, in other embodiments In, multiple bars 1630 even can not be cylinder, but square, rectangle or any other shape, do not take off all From the scope of the utility model and content, as long as it provides any kind of localization support for impact surface.Except bar 1630 Outside the change of geometry, the placement of bar 1630 needs not be the whole inwall for being distributed on face chamber 1616, in fact, bar 1630 position can be placed on any one opening position in many positions, all without departing from the scope of the utility model and Content.Finally, it should be noted that in an alternate embodiment of the present utility model, face chamber 1616 even can need not be any Support bar 1630, and in the case of the scope of the utility model and content is not departed from, face chamber 1616 can be completely hollow 's.

Figure 17 of accompanying drawing shows the golf according to embodiment of the present utility model shown in Figure 15 and Figure 16 The decomposition diagram of club head.More specifically, this decomposition view allows the impact for being shown more clearly that glof club head 1700 Relation and assembling between face insert 1718 and face chamber 1716.It should be noted that referred to although discussing earlier using forging process altogether Different metal will not be able to be easily welded together links together, but the main body of glof club head 1700 and Connection between striking face insert 1718, which is related to, may cause during striking face insert 1718 deforms during forging technology The empty part of face chamber 1716.Fortunately, in current embodiments, the material for striking face insert 1718 can be similar In the material of main part 1700, this allows to use conventional soldering techniques after miscellaneous part to be total to forging together by described two Individual part links together.

Another for being worth identification is characterized in the length of multiple bars 1730.In order to provide structure for striking face insert 1718 Support, multiple bars 1730 can typically contact the rear surface of striking face insert 1718.Or the it can be said that end of multiple bars 1716 The rear surface that end can contact striking face insert 1718 is strengthened with providing structure.However, in an alternative embodiment, it is more The end of individual bar 1716 can not just reach the rear surface termination of striking face insert 1718, create a gap；When with height Promote face flexure when golf ball is hit, at the same after creating backstop (backstop) to keep the bullet of the material of striking face insert 1718 Property deformation.

Figure 18 of accompanying drawing is shown with using above-described one or more weight that forging process links together altogether 1815 and lid 1817 glof club head 1800 rearview.Above-described technique is not repeated, Figure 19-Figure 20 will be shown By using the above-described toe for a variety of parts that forging process creates altogether and with decomposition view.

Figure 19 shows the toe perspective view of the decomposition of glof club head 1900, shows according to this reality of the present utility model Apply a variety of parts of the Weighting system of scheme.The decomposition view of glof club head 1900 is not intended to create the side of Weighting system Method is shown, but is presented at this to illustrate how to be used together the part in above-described forging process altogether to create height Golf ball head 1900.More specifically, the Weighting system includes weight chamber 1916, weight 1915, lid 1979 and welding material herein Material 1920.Weight chamber 1916 is formed at this in rough forging step, after this, will weight with lid 1917 using welding material 1920 1915 positioning weldings are measured in weight chamber 1916.After a variety of parts are cursorily connected to each other, whole glof club head 1900 are subjected to such as the final forging step described in Figure 13 A and Figure 13 B above.

Figure 20 show the decomposition of golf clubs 2000 with perspective view, show according to this implementation of the present utility model A variety of parts of the Weighting system of scheme.Similar to the discussion above with respect to Figure 19, there is provided this view with show the part it Between relation.

In addition to the above, the current multi-step forges method and is different from that it can be no longer in place of the pure method of forging altogether altogether It is required that two kinds of materials have similar flow stress between different materials.Eliminating the need for material has similar flowing should This requirement of power can be beneficial, because it allows the material using wider range, particularly when its use provides pole It is even more so during special material (such as tungsten) of the counterweight benefit at end.The method of forging can be by using altogether for the current multi-step Before weight adjustment member is entirely encapsulated in lid types of material by the gap around final lid types of material filled cavity, forging The chamber for the weight is made to realize this purpose.Although eliminate the need for the material with similar flow stress Will, but in this multi-step altogether forging method, remain that the thermal coefficient of expansion of the second material is less than the first material.It is this to want It is still existing to ask, although because second material is included in intracavitary via lid, is still subjected to the with outside One material identical forging temperature.Any excessive expansion of second material will reduce the rigidity of structure of the lid, cause to be bonded Potentially failed in method.

Figure 21 of accompanying drawing is shown to be divided according to the glof club head 2100 of an alternate embodiment of the present utility model Diagrammatic view.According in this alternate embodiment of the present utility model, glof club head 2100 can contain with being previously described Very similar part, such as with multiple high density weight adjustment members similar on Fig. 6 and Fig. 7 discussion in the early time 2115th, multiple lids 2117, lightweight weight adjustment member 2114 and impact surface 2218.However, it can here be seen that lightweight weight Amount adjustment member 2214 seems to be that it now incorporates elder generation with the significant difference of the embodiment of prior art herein Preceding unshowned unique geometry.More specifically, lightweight weight adjustment member, which is also wrapped, to be shown to more going through for Figure 21 Include multiple otch 2140 across lightweight weight adjustment member 2114.It is it is to be noted here that current exemplary herein The multiple otch 2140 shown in embodiment can substantially uniformly divide across whole lightweight weight adjustment member 2114 Cloth, to promote the uniform bonding between a variety of parts, without departing from the scope of the utility model and content.By this knot of otch 2140 Close in lightweight weight adjustment member in many-sided performance for improving glof club head.On the one hand, with reference to multiple The most direct and recognizable benefit of otch 2140 is that the weight of lightweight weight adjustment member 2114 is further reduced.Except Outside the benefit for removing weight from lightweight weight adjustment member 2114, multiple otch 2140 can be used for trickle but extremely important Purpose --- help lightweight weight adjustment member avoid its position relative to glof club head 2100 and impact surface 2128 Skew.

It should be understood that current glof club head 2100 is created using forging process altogether as described above, a variety of portions The ability that part is formed in (solidary) structure of close concern to each other together for overall club head 2100 normal function very It is important.When insert is added near the striking face portion 2128 in glof club head 2100, this structural intergrity becomes very To more important.In order to assist in keeping the structural intergrity of a variety of parts, multiple otch 2140 allow some materials of impact surface 2128 Material is flow in otch 2140, creates the more preferable bonding between different parts.This deformation of the material of impact surface 2128 passes through Material is prevented to offset relative to each other to help to improve the bonding between part via mechanical interface, which increase structural integrity Property.Finally, because main part is made of the material similar with striking face portion 2128, so by striking face portion 2128 This anamorphic effect of displaying can occur in the rear surface of lightweight weight adjustment member 2114 and glof club head 2100 Main body at, without departing from the scope of the utility model and content.
