Technical field

The utility model relates generally to a kind of forge glof club head altogether made of two or more material With the method for manufacturing this glof club head.More specifically, the utility model is related to high by preforming blank manufacture swage Golf ball head, the blank two or more included material before practical forging technology, as a result, being formed The glof club head of multiple mixed materials does not need to any subsequent manufacturing procedures, such as mechanical processing, welding, swaged forging, bonding Deng.

Background technology

Golf is difficult！When common horizontal sportsman brandishes golf club, he or she is brandishing golf club When will appear unexpected variation, lead to numerous eccentric impacts, this leads to the reduction of achievement compared with direct center impacts.So And attempting common horizontal sportsman is made more to enjoy this very difficult movement, golf club design person proposes solely Special golf club design can mitigate the harsh fact of faulty golf.

In a previous example, the United States Patent (USP) 4,523,759 of Igarashi discloses a kind of sky of perimeter weighting Heart Golf club iron, with foam core, which has the effective hitting area concentrated to the centre of moment, tries hard to make golf sports Easily.The distribution of weight of golf club on periphery is made to the rotary inertia (MOI) of glof club head enhance, is reduced when height When golf club hits golf, the bad torsion of golf club.

The United States Patent (USP) 4,809,977 of Doran et al. shows another embodiment, attempts by golf club The heel and toe of head set additional weight to increase the rotary inertia of glof club head.By increasing heel and toe Weight realizes the increase of the rotary inertia of glof club head, can further prevent golf club in heel and toe side Upward torsion, which reduce the ill effects that golf is deviateed to expectation track.

Although increase the inclusiveness of golf club for common horizontal sportsman and the preliminary of playability attempts to be to be worth praising Reward, but it obtains the inclusiveness of the limit not over different materials are used forming the different piece of glof club head. In one embodiment, the United States Patent (USP) 5,885,170 of Takeda illustrate using multiple material it is more extreme adjust quality The advantages of characteristic.More precisely, United States Patent (USP) 5,885,170 teach a kind of ontology, with surface and hosel, the table Face is formed of one material, and hosel is formed by another material different from the proportion of rod head noumenon.Helmstetter et al. United States Patent (USP) 6,434,811 illustrate another embodiment that glof club head performance is improved using multiple material, By Weighting system being set to realize on glof club head, the Weighting system after whole glof club head is formed with It is combined.

Recently, the improvement that multiple material is attached to glof club head is significantly ripe, by using mechanical processing chamber The composite material of a variety of different characteristics is attached in glof club head.More precisely, the United States Patent (USP) 7 of Cole et al., 938,739 disclose it is a kind of with the glof club head of cavity integrated with glof club head, wherein, the cavity is by heel Region extends to toe area, and the lower part along the back side of glof club head extends, and is roughly parallel to impact surface extension, and It is substantially symmetric about the center line for traversing glof club head between heel area and toe area.

However, because multiple material golf club is introduced into after the completion in ontology, between different materials The tolerance at interface may cause the sense of touch for changing glof club head to generate undesirable side effect.The U.S. of Hettinger et al. Patent 6,095,931 confirms this adverse side effect that sense of touch is sacrificed by using a variety of heterogeneities.United States Patent (USP) 6, 095,931 solves this and asks by providing separation layer between the main part including impacting forepart in glof club head Topic.

The United States Patent (USP) 7,828,674 of Kubota recognizes the seriousness of this problem, and which depict with viscoplasticity member The hollow golf club heads of element can allow horizontal preferably sportsman to feel light and hollow, therefore they do not like this golf Bar.The magnesium of recess portion that United States Patent (USP) 7,828,674 is used only the metal of metal cap sealing and is formed by combining embedded and/or press-in Block solves the defects of golf club of this composite material.

It all tries concurrently to touch golf club to improve the trial of glof club head performance although above-mentioned The sacrifice of sense minimizes, all these methods are required for a large amount of subsequent manufacturing procedures, these subsequent manufacturing procedures are in head It is middle to generate the cavity and groove for being used for combining second of material.The auxiliary process of these types is not only expensive, and it is a variety of into The solid sense of touch that/sufficiently tight tolerance of holding usually has to ensure integrally formed glof club head is ten Divide difficulty.

Therefore, can find out from upper content, although all improvement for preparing glof club head of sense of touch can be not sacrificial Make its inclusiveness more preferable in the case of the sense of touch that domestic animal conventional club head has, but without using the follow-up of bad sense of touch can be caused In the case of technique, the prior art is unable to sense of touch and produces such club.

Specific embodiment

Following detailed description is the current optimal desired mode for implementing the utility model.The description is not considered as limiting Meaning processed, but be merely illustrative the purpose of the General Principle of the utility model because the scope of the utility model be by What appended claim most preferably limited.

The feature of various utility models is described below, each feature can be used independently of each other or with other features It is used in combination.However, any single utility model feature possibly can not solve the problems, such as it is above-mentioned any one or all ask Topic one of can only solve the above problems.It further says, above-mentioned one possibly can not be fully solved by following features A or multiple problems.

Exemplary embodiment according to the present utility model, Fig. 1 of attached drawing show the perspective of glof club head 100 Figure.The glof club head 100 shown in Fig. 1 generally includes main part 102 and hosel (hosel) part 104, main part 102 have multiple individually identified components recognized such as top line (topline) part 106, bottom 108, heel 110 and toe 112.The glof club head 100 of exemplary embodiment according to the present utility model generally includes at least one mounted in golf Weight adjustment member among the main part 102 of head 100.In a preferred embodiment, the utility model is not being departed from In the case of range and content, weight adjustment member can integrally be fitted into main part 102 to ensure weight adjustment section Divide and be fixed in main part 102.Since weight adjustment member is integrally packed into the main part of glof club head 100 In 102, these weight adjustment members are sightless in figure 1 of the accompanying drawings.But when providing different views, these are heavy Amount adjustment member will be shown specifically in the figure below.

Before with reference to subsequent attached drawing, it is worth it is noted that current glof club head 100 is using forging Technique manufacture is made, does not need to any follow-up finishing operations with reference to the weight.This establishes an important characteristic, due to Achieve the effect that and it is identical to be integrally packed into weight adjustment member to be very tired using the optional manufacturing process of such as casting etc. Difficult.Specific internal component is packed into outside individually as " being integrally packed into " described in the utility model is normally defined In parts, and there is no connector or seam in finished product.For the utility model, in the main part of glof club head 100 " being integrally packed into " weight adjustment member is divided in 102 to typically refer to weight adjustment member being arranged on the master of glof club head Subsequent manufacturing procedures, such as milling are usually required inside body portion 102 and without connector or the ability of seam, connector and seam It cuts, weld, being brazed, being bonded or swaged forging etc..

Here it is further noted that in the case where not departing from the scope of the utility model and content, in the utility model It is current as defined in the range of " being integrally fitted into " weight can make in finished product weight inside some in terms of exposure, with aobvious The presence of weight adjustment member is shown.More specifically, it " is integrally packed into " and refers to manufacturing as described above finally The method of product is not necessarily limited to visually hide weight adjustment member.

Fig. 2A -2D show example embodiment according to the present utility model for manufacture it is common forging glof club head 200 Method.More specifically, Fig. 2A -2D show that the glof club head 200 for being related to being formed finished product by blank material 201 is included Forging step.

Fig. 2A shows the preforming blank 201 of example embodiment according to the present utility model.As that can be seen in Fig. 2A Go out, which is typically initially the cylindrical bar formed by the first material, because it is usually used in glof club head 200 forging.In order to manufacture the weight adjustment member that can be integrally fitted into the main part 202 of glof club head 200 215, one or more cavitys 216 are processed inside preforming blank 201.The present example embodiment shown in fig. 2 In, two cavitys 216 of machining in the end of preforming blank 201.The position of cavity 216 inside preforming blank 201 It puts and is important with shape, because of its most final position with the weight adjustment member 215 inside the glof club head 200 after forging It puts directly related.

Referring to Fig. 2 B, it can be seen that once machining cavity 216, cavity 216 is filled partially with and the first density of material The second different material, to manufacture weight adjustment member 215.It is similar with above discussion, the position of weight adjustment member 215, The position of size and shape and cavity 216, size and shape no less important, because of the weight tune in preforming blank 201 Whole point 215 related to the final resting position of the weight adjustment member in glof club head.

Finally, Fig. 2 C show the terminal stage of preforming blank 201, at this point, the remaining space of cavity 216 is by the first material Material fill up and for example, by weld, be brazed and the Conventional attachment methods of swaged forging seal.Sealing cavity 216 makes weight adjustment member 215 can integrally be fitted into the main body of preforming blank 201, this makes it possible to same 215 one of weight adjustment member Ground is fitted into the main body 202 of the glof club head 200 after forging technology.After cavity 216 is filled, preforming blank 201 are subjected to and the relevant conventional wrought processes of the forging of glof club head 200.Although forging glof club head 200 relates to altogether And basic step to understanding that the utility model is particularly significant, it is related to a kind of relatively outmoded and set technology, in the application Details excessively no longer is goed deep into this.About the basic glof club head being related to without being integrally packed into weight adjustment member Forge step more detailed information can in the United States Patent (USP) 6 of the United States Patent (USP) 3,825,991 of Cornell and Iwata et al., It is found in 666,779, the two patent disclosure of that are all generally introduced by quoting it.

Although discussed above is about common forging golf club, practical forging technology is described by reference well, It is also without solving the problems, such as that the common forging process related with current utility model is subsidiary, wherein at two kinds involved in forging technology not Same material.More specifically, because weight adjustment member 215 is made of the second material, second material is made with being used for The first material for making the remainder of preforming blank 201 is different, so it must be particularly noted that ensuring that different materials can be forged Make formation glof club head 200 together.Therefore, in order to select that two kinds of polymeric materials together can be forged altogether, this first Material and the second material are usually required that with the special material property related with flow stress and its coefficient of thermal expansion.Although most Preferably both materials is keep forging consistency to have identical material property, but cannot carry using identical material For any adjustment of weight effectiveness needed for the principle of the utility model.

First, it in order to make metal material that there is the ability that can be forged altogether together, needs suitably to consider that each material is each From flow stress.The flow stress of material can be generally defined as making needed for material continuous deformation (keeping metal flow) Instantaneous value, combining forging components by the manufacture of two kinds of different materials needs stress when they are subjected to forging technology with opposite phase Same speed flowing.It is well known that the flow stress of material is typically the function of yield strength, the flow stress of material is led to Often it is summarised as 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 aforesaid equation, it is that the flow stress of material can be not interpreted as in a vacuum referred in this to be worth Flow stress, more precisely material forging temperature function.Therefore, the present example embodiment of the utility model In, the under its second forging temperature of first flow stress of first material under its first forging temperature and the second material Two flow stresses are roughly the same but differ, and the first forging temperature and the second forging temperature are roughly the same.More specifically, more In detailed embodiment, the first material can be 1025 steel, have about 10ksi under about 1200 DEG C of forging temperature First flow stress of (thousand pounds are per square inch), while the second material can be niobium material, in about 1100 DEG C of forging At a temperature of have about 12ksi the second flow stress.

Although in the utility model exemplary embodiments mentioned above, the first material can be 1025 steel, and the second material can To be niobium material, but in the case of without departing from the scope of the utility model and content, as long as in similar forging temperature Other multiple materials with similar flow stress can also use down.In other words, if the second flow stress be not higher than or Person is not less than the 20% of the first flow stress, then any two material may be used in current work forging process.

It has been observed that other than flow stress, the coefficient of thermal expansion of the first and second materials also to suitably forging two kinds altogether Different materials are particularly significant.More precisely, the first coefficient of thermal expansion of the first material is typically greater than or at least equal to the Second coefficient of thermal expansion of two materials.Because coefficient of thermal expansion is directed to the Material shrinkage after forging, it is important that integrally Encapsulating the first material of the second material, there is high thermal expansion coefficient to be used to prevent the interface portion in material from forming gap.In this reality With in novel more detailed embodiment, the first material can be 1025 stainless steels, swollen with about 8.0 μ in/in °F heat Swollen coefficient, while the second material can be niobium, have about 3.94 the second coefficient of thermal expansion of μ in/in °F.

It is worth noting that, although in the above exemplary embodiments, the second coefficient of thermal expansion is less than the first thermal expansion system Number, but in the case where not departing from the scope of the utility model and content, which can be identical, to realize two kinds of materials Perfect cooperation.In fact, in the exemplary embodiment of the utility model, preferably the first material and the second material have equally Coefficient of thermal expansion because excess shrinkage of the exterior material on internal material may result in the interface portion production of two kinds of materials Raw additional stress.

Optionally, it attempts to provide different weight characteristics, the second material can be made of 6-4 titanium material, to reduce weight The weight of adjustment member 215.Titanium material under about 1100 DEG C of forging temperature usually with about 10ksi flow stress and About 6.1 μ in/in °F coefficient of thermal expansion.

Now, to forging technology and being involved in the problems, such as that different materials forge special attention and discussed altogether, the figure of attached drawing 2D shows the perspective view of glof club head 200 completed using the above-mentioned manufacture of forging process altogether, wherein glof club head 200 At least one weight adjustment member 215 is integrally packed into main part 202.More specifically, working as in the utility model In preceding exemplary embodiment, weight adjustment member 215 is located near the heel 210 of glof club head 200 and toe 212.It will Weight adjustment member 215 is set as near heel 210 and toe 212 so that glof club head 200 is not needing to be any Assist that there is increased rotary inertia (MOI) in the case of attended operation, this will cause to generate more when impacting golf Consistent sense of touch.

Before carrying out being related to the discussion of the utility model difference embodiment, it is to be noted here that golf club The accurate location of weight adjustment member 215 in first 200 main part 202 in each different glof club head slightly Difference, this is that the utility model is total to the result that forging process includes different materials.More specifically, weight adjustment member 215 is really It is also different in each golf club 200 to cut position, because the flow stress of the first material and the second material can assist in The final position of weight adjustment member 215.In addition to the above, it is notable that in the weight of glof club head 200 Interface between adjustment member 215 and main part 202 usually can be irregular interface, with serrated boundary to show Entire glof club head 200 is by forging altogether.This differs markedly from the following process auxiliary operation for example, by milling and drilling The cavity of manufacture, there are two types of the clear lines of demarcation of different materials for the cavity usually tool manufactured by following process auxiliary operation.

Fig. 3 A-3D of attached drawing show the alternative embodiment of the utility model, the individual weight adjustment member of two of which 314 and 315 are located at the different piece of preforming blank 301 to manufacture the glof club head 300 with different performance standard.More Glof club head 300 particularly, to show in fig. 3d has near the top line part 306 of glof club head 300 Light weight adjustment member 314 has the weight adjustment member 315 of weight near the bottom of glof club head 300 308, with Help reduces the center of gravity (CG) of glof club head 300 so as to contribute to hitting for the glof club head 300 of current utility model Ball and the characteristic of rotation.

Similar with front, Fig. 3 A-3C show the construction process of the utility model glof club head 300, the process by Preforming blank 301 starts.More specifically, Fig. 3 A show the preforming blank of exemplary embodiment according to the present utility model 301 perspective view, wherein, drill out a plurality of cavities 316 in the key position of blank 301.It is worth noting that, in present exemplary In embodiment, a plurality of cavities 316 are drilled out near the upper and lower part of preforming blank 301 rather than are drilled out in each end Cavity 316 because this specific embodiment focus on by by weight from the top line part 306 of glof club head 300 to height Move the center of gravity to reduce glof club head 300 in the bottom 308 of golf ball head 300.

Fig. 3 B of attached drawing show two adjustment of weight parts 314 and 315 being located in cavity 316 made of Fig. 3 A.Though So, when wishing to lower the center of gravity, it is often desirable that the weight of 300 adjacent upper part of glof club head minimizes, but this practicality is new The upper cavity 316 of the present example of type can not be complete empty, because all preforming blank 301 will be finally forged into The shape of glof club head 300, this can cause collapsing for the cavity 316 of arbitrary sky.Therefore, in the current of the utility model In exemplary embodiment, upper cavity 316 is filled with light weight adjustment member 314, while lower cavity 316 is filled with weight Weight adjustment member 315.Light weight adjustment member 314 is usually made of the third material with third density, wherein heavy Weight adjustment member 315 is usually by having the second material of the second density to be made.In the exemplary embodiment of the utility model, Third density is usually less than 7.0g/cc, wherein the second density is typically larger than 7.8g/cc；It is used to form glof club head simultaneously First material of 300 main part 302 usually has the first density of about 7.8g/cc.

Fig. 3 C of attached drawing show the terminal stage of preforming blank 301, in the internal cavities of preforming blank 301 Weight adjustment member 314 and 315 is integrally packed into 316.More specifically, the manufacture of the preforming blank shown in Fig. 3 C relates to And the first material is filled so that weight adjustment member 315 and 316 is fitted into preforming blank 301 in the remaining space of cavity 316. With discussed above similar, show that preforming blank 301 is then forged production glof club head 300 in Fig. 3 D, wherein heavy Amount adjustment member 314 and 315 is integrally enclosed in the main part 302 of glof club head 300.

Similar with the above method, the common forging of the third material in the cavity produced in the first material, third material is usual Need there is the third flow stress similar with the first flow stress of the first material, and third coefficient of thermal expansion is less than first First coefficient of thermal expansion of material.More specifically, in the exemplary embodiment of the utility model, third material can be 6- 4 titanium material have the third flow stress of about 10ksi, and with about 6.1 μ under about 1100 DEG C of forging temperature In/in °F of third coefficient of thermal expansion.

Although Fig. 2A -2D and Fig. 3 A-3D show the different embodiment of the utility model, it is respectively used to obtain higher MOI and lower CG, but these features nor repel each other.In fact, the utility model as shown in Fig. 4 A-4D Further alternative embodiment, in the case of the scope of the utility model and content, feature can be derived from above-mentioned beg for The embodiment of opinion, to manufacture the common forging glof club head with higher MOI and lower CG.More specifically, Fig. 4 A-4D are shown Light weight adjustment member 414 is combined near the top of golf club 400 406 and in glof club head 400 Toe 412 and heel 410 nearby combine the weight adjustment member 415 of two or more weights, with production with higher MOI and more Step needed for the golf club of low CG.

Fig. 5 A-5D of attached drawing show the further alternative embodiment of the utility model, wherein, glof club head 500 Main part 502 can include the weight adjustment member 514 being integrally packed into.In the present example embodiment of the utility model In, weight adjustment member 515 can have relatively large size, when forging technology is completed, can substitute golf The major part of the main part 502 of head 500.In the current optional exemplary embodiment of the utility model, integrally it is packed into Weight adjustment member 514 can be usually made of the third material with third density, the third density be substantially less than be used for The first density of the first material of 500 main part 502 of glof club head is formed, weight is made to be led from glof club head 500 It is removed in body portion 502.Because the light third material for being used to form weight adjustment member 514 is usual compared with the first material It is relatively soft, therefore weight adjustment member 514 is generally integrally packed into the inside subject of glof club head 500, not sacrificial Reach the notable mitigation of weight in the case of domestic animal sense of touch.

More specifically, Fig. 5 A of attached drawing are similar to the attached drawing of front, preforming blank 501 is shown.However, show currently In example property embodiment, the cavity 506 inside preforming blank 501 itself is significantly greater.In figure 5B, the big cavity 506 The weight for being used for adjusting glof club head 500, density and whole sense of touch can be filled with weight adjustment member 514 later. In Fig. 5 C, similar to described above, be subjected to forging technology in entire preforming blank 501 with manufacture glof club head 500 it Before, the remaining space of cavity 516 is filled with original first material.

It is noted here that in the present exemplary embodiment, the hosel part 504 of glof club head 500 is special The first conventional material of meaning is made, because being used to form the flexural property of the second material of weight adjustment member 514 usually not It is suitble to the bending requirement of iron golf club head 500.More specifically, it is used to form the third material of weight adjustment member 514 Expect it can is lightweight iron aluminum material of the density less than 7.10g/cc, preferably less than 7.05g/cc, more preferably less than 7.00g/cc, all without departing from the scope of the utility model and content.However, without departing from the scope of the utility model and interior In the case of appearance, as long as the density of third material is within the above range, many other materials, which can also be used as, is used to form weight The third material of adjustment member 514.

Fig. 6 of attached drawing shows the further alternative embodiment that forging process is total to using multi-step according to the present utility model Glof club head 600 decomposition rear perspective view.This multi-step be total to the detailed content of forging process by subsequent Fig. 8- Described in 14, which is accurately positioned the energy of different weight component in the different component internals of glof club head 600 Power.The raising of this ability for being accurately positioned wt pts is not only that a variety of different materials forgings provide possibility together, In the past due to material it is intrinsic to limit this be impossible, but also makes the performance characteristics of golf club 600 compared with having in the past More improvement.

More specifically, Fig. 6 of attached drawing shows the common forging glof club head that forging process manufacture is total to using multi-step 600.Glof club head 600 corresponds to its respective cavity 616 in the heel 610 of glof club head 600 and toe 612 Weight adjustment member 615 with density bigger.Weight adjustment member 615 is combined to make weight adjustment member with lid 617 615 main body with glof club head 600 during common forging process keeps together.It is worth noting that, present exemplary Glof club head 600 using multi-step be total to forging process install the weight adjustment member 615 of weight without for example welding, pricker Weldering, swaged forging or similar following process.As previously mentioned, it is the uniformity and one of material using the benefit of this forging process altogether Cause property has achieved remarkable performance and sense of touch.However, in addition to the benefit of above-mentioned elaboration, the current implementation of the utility model Example makes the adjustment of weight part 615 of weight be placed on the end of glof club head 600, further improves glof club head 600 position of centre of gravity and rotary inertia.

Fig. 7 such as attached drawing shows the glof club head 700 of further alternative embodiment according to the present utility model The front perspective view of decomposition.More specifically, being total in forging process in multi-step, glof club head 700 is in glof club head 700 The internal combustion lightweight weight adjustment member 714 of cavity 716 behind 718 part of impact surface.Current in the utility model is shown In example property embodiment, according to aforementioned accurate common forging process, the position of lightweight weight adjustment member 714 can be more accurately set It puts and is laid out, therefore create the chance of the weight for 718 part of impact surface for reducing glof club head 700.Work as to understand Preceding multi-step is total to forging process, and Fig. 8-14 presented below, which is described in detail, is related to the step of multi-step is total to forging process.

Fig. 8 of attached drawing is similar with Fig. 2-5 previous, shows the preforming blank for producing common forging glof club head 801.This forging blank 801 is bent into L-type as shown in Figure 9, by forging work described preparing blank 901 for punching block Skill.Figure 10 a and 10b show the front view and rearview of glof club head 1000, are subjected to multi-step and are total to forging process The first step.In this preliminary step, blank forging is molded, which is approximately similar to glof club head 1000.It is true On, even if the stage in the early stage, it is also seen that the shape of glof club head 1000, because it has had hosel part 1004th, heel 1010 and toe 1012.In the rearview of the glof club head 1000 shown in Figure 10 a, from golf club The heel 1010 and toe 1012 of head can see the preliminary trace of cavity 1016, while the Gao Er shown in figure 10b Cavity 1016 can also be seen in the front view of husband's club head 1000 near impact surface.

After initially forging step, additional decoration (trim) 1030 can be removed from glof club head 1000, And it is then subjected to another blank forging step.In forging process, extra material can be from the boundary of punching block to outflow Go out, lead to " flash of light " being commonly called as.This glittering material as elucidated before can be got rid of between each more forging steps (flash material), to promote to be attached to punching block in subsequent step.

The result of the second forging step can be shown from such as Figure 11 a and 11b.It can such as be seen in Figure 11 a and 11b It arrives, the glof club head 1100 under current state starts to show the more close shape similar to final products.It removes It more determines outside global shape, the boundary of cavity 1116 and shape also begin to show respective shape.In the second forging step After rapid, before glof club head 1100 is subjected to finally forging step, weight adjustment member can be added to specifically In cavity 1116.

Figure 12 a and 12b can clearly show the weight adjustment section of the cavity 1116 on glof club head 1100 / relationship.Here, from Figure 12 a and 12b it can be seen that weight adjustment member 1215 can be used to fill glof club head The cavity 1216 at 1200 rear portion, the weight adjustment member 1215 usually have the main body higher than glof club head 1200 Density.The high density weight adjustment member 1215 usually can covered with lid 1217, the lid 1217 by with glof club head 1200 similar materials are made so that high density weight adjustment member 1215 is maintained within cavity 1216.In golf club First 1200 forepart, cavity 1216 can adjust structure with the lower weight of the main part density of packing ratio glof club head 1200 Part 1214.Similar to rear portion, this weight adjustment member 1214 can be fixed on also as the mechanism of the scope of attack 1218 Lid cavity 1216 in.Similar to lid 1217, impact surface 1218 can be by similar with the main body of glof club head 1200 Material is made.Lid 1217 and impact surface 1218 are made with the material identical with the main body remainder of glof club head 1200 It is advantageous, because it allows to the main part to glof club head 1200 by both components weldings.By these groups Part is welded to appropriate position, allows before finally the current multi-step of forging step completion is total to forging process, by weight adjustment section 1215 are divided to be fixed to its respective cavity 1216.

In the alternative embodiment of the utility model, lid 1217 is even not necessarily required to be completely covered cavity 1216 and again Measure adjustment member 1214.In fact, in the alternative embodiment of the utility model, 1217, lid needs part to a certain extent Covering weight adjustment member 1215, this is substantially prevented from main body point of the weight adjustment member 1215 from glof club head 1200 From.

The final forging process that this process includes is typically to manufacture it can be seen that being the glof club head of " forging altogether " 1200, because glof club head 1200 at this time includes two or more differences that can be forged in final step together Material.Figure 13 a and 13b show result of the glof club head 1300 after the final step of forging altogether of its completion.In current shape Under state, glof club head 1300 is its final shape, and weight adjustment member 1316 and 1314 all passes through lid 1317 and impact Panel 1318 is integrally fitted into its respective cavity.Even if glof club head 1300 can take their shape, in height There are still extra flashes of light 1330 around golf ball head 1300, need to become it finally in glof club head 1300 It is modified before shape.

Figure 14 a and 14b show result of the glof club head 1400 of completion as forging process altogether.In Figure 14 a and 14b In as can be seen that extra flash of light 1330 have already passed through rest and reorganization, improve the aesthetic feeling of glof club head 1400.It is as previously mentioned , due to this forging process altogether, weight adjustment member 1416 and 1418 by lid 1417 and impact panel 1318 seamlessly and one Body it is packed into the main body of glof club head 1400.As discussed earlier, by this forging process that is total to by weight adjustment member 1416 be seamlessly and the advantages of integrally loading in the main body of glof club head 1400 to prevent strenuous vibration and improve Gao Er The solid sense of touch of husband's club head 1400.In fact, using this technique, current golf club head, which can reach, utilizes tradition forging Make the sense of touch that single forging glof club head of method forging can not be realized.

In other words, it can say in this way, multi-step forges method its institute of weight adjustment member 1416 and 1418 in place altogether at present Cavity 1216 (see Figure 12) between create unique relationship.More specifically, it may be said that weight adjustment member 1416 Exterior surface area is usually identical with the inner surface area of cavity 1216.Cavity 1216 can usually include completing cavity 1216 Arbitrary lid 1217 or panel 1218 surface region, which is produced by rough forging step.(referring to Figure 12) even if Symmetric shape and surface area between cavity 1216 and weight adjustment member 1416 may be real unlike innovation achievement Situation is, unless being related to common forging step, this seamless interface between two kinds of components is unable to reach.In view of being used for height The combination limitation of the material of golf ball head difference component, the common forging method innovated at present is only to be reached between these components Into the method for seamless interface.
