Degree is 671-773HV；The golf club head tensile strength of aluminium alloy manufacture is 402-427MPa, hardness 628-723HV.To sum up
The golf club head that is described, being manufactured using above-mentioned material cannot always reach ideal requirement in the various aspects of performance.
Likewise, the striking surface of golf club head is made of non-crystaline amorphous metal, it is the high resiliency pole based on amorphous alloy material
Limit and preferable tensile strength and hardness.
Above-mentioned non-crystaline amorphous metal is zirconium-base amorphous alloy, magnesium base amorphous alloy, cu-based amorphous alloys, ni-based amorphous alloy, aluminium
Base noncrystal alloy, rare-earth-base amorphous alloy, Fe-based amorphous alloy, cobalt base amorphous alloy, titanium-based amorphous alloy, more entropy non-crystaline amorphous metals
One or more of combination.
Non-crystaline amorphous metal includes the non-crystaline amorphous metal kind that sill is Zr, Ni, Fe, Cu, Al, Mg, Co, Ti, V and rare earth etc.
Class.In the present invention, not to being defined as the shaping raw material of golf club head using which kind of non-crystaline amorphous metal, but in reality
The type of non-crystaline amorphous metal can be selected in situation according to the required performance of golf club head.Non-crystaline amorphous metal generally all has higher
Tensile strength, higher elastic limit, outstanding anti-fatigue performance, larger elastic limit and good corrosion resistance, but
It is the non-crystaline amorphous metal of different substrate materials material in performance or difference, golf club head can selects amorphous according to actual needs
The type of alloy.
In the present invention, golf club head is non-crystaline amorphous metal golf club head, and amorphous alloy material has higher elasticity
The limit and preferable tensile strength and hardness, and its in-fighting is small.Non-crystaline amorphous metal is the manufacture for being highly suitable as golf club head
Material.The elastic limit of the golf club head manufactured with non-crystaline amorphous metal is preferably 80-100GPa, and tensile strength is preferably 1170-
1800MPa, hardness are preferably 700-900HV., it is clear that elastic limit, the tension of the golf club head of non-billon manufacture
Performance in terms of intensity and hardness is better than stainless steel, titanium alloy and aluminium alloy.For example, when golf club head is Ni-based amorphous
When alloy, hardness 780-850HV, tensile strength 1230-1670MPa, in terms of hardness and tensile strength better than not
Become rusty steel, titanium alloy and aluminium alloy.
As shown in attached drawing 1-9, golf club head 1 is Openworks shape.The Openworks shape of golf club head mainly leads in the present invention
It crosses striking surface to embody, in conjunction with the material property that the high-strength height of amorphous alloy material is hard, golf club head is designed as Openworks shape,
On the one hand the elastic property of golf club head can be improved, another aspect Openworks shape keeps golf club head thickness uniform, is closed in amorphous
During gold molding golf club head, the contraction of golf club head is consistent.The thickness of golf club head is uniform, in forming process

In bright, preferably the striking surface of golf club head is equipped with recessed portion（It is not identified in figure）, it is in cambered surface to make striking surface.Striking surface is arc
Face increases the contact area of striking surface and golf, can increase ball speed in the case where hitting power is constant so that golf
The kinetic energy of bigger, flight stroke bigger are obtained in the moment hit.When striking surface is arc, the power collection of golf declines
The center of arc, opposite, the power of golf club concentrates on the position at arc center and is conducted to golf when swinging,
Golf fortune is contributed to play more preferable batting horizontal.Striking surface also can effectively prevent golf when being arc and hit
Moment occur direction offset.
Referring again to attached drawing 4-9, the striking surface of golf club head is equipped with cavity 22 and stress rib 21.Preferably, stress rib
Cross section be in dentation or arcuation so that the cross section of golf club head in comb teeth-shaped or bow word connect shape.
The cross section of stress rib 21 is in dentation, and square stance stress rib surface is by the extruding force of golf, stress rib hair
Raw deformation, is become from extruding force to the drawing force of both sides deformation.The cross section of stress rib is in dentation, is had time between adjacent stress rib
Chamber 22, when elastic deformation occurs for stress rib, the dynamics for not contacting or contacting between adjacent stress rib is little, adjacent stress rib
Between opposite force would not cancel out each other, or offset power it is smaller.In this way, stress rib can be by more elastically-deformable energy
It is again converted to the momentum of golf.
21 cross section of stress rib is arcuation, and in addition to the cavity 21 between stress rib, the inside same design of stress rib is sky
Chamber, and cavity is open-type so that stress rib cross section is arcuation.Cavity is open-type, is conducive to the molding of golf club head,
Reduce the difficulty of striking surface at the time of molding.Stress rib cross section is arcuation, in the upper surface of square stance stress rib by golf
The extruding of ball, elastic deformation, which occurs, makes stress rib bottom surface by certain drawing force, when elastic deformation occurs, stress rib
The power that middle section is subject to is smaller, so when stress rib is too thick, it is extra that stress rib middle section, which is most of,.It will
Stress rib interior design is cavity, on the one hand can save the material of striking surface, reduces manufacturing cost, on the other hand makes striking surface
Each position thickness it is uniform, be conducive to striking surface molding, avoid causing to make because in uneven thickness each position of striking surface
Mechanical property is different.Striking surface can be integrally formed with the main body of golf club head, also can separately as a parts-moulding,
In the present embodiment, striking surface is an individual parts.It is cavity inside stress rib, square stance golf is to stress rib
Extruding become elastic deformation, due to being cavity inside stress rib, stress rib will not be contacted with other places and by elastic deformation
Energy expenditure fall, therefore the in-fighting of striking surface energy can be reduced, increase the instantaneous kinetic energy of square stance golf, flight is more
Far.
In the present invention, stress rib is preferably and is formed and be closed in striking surface for the annular being closed, stress rib on striking surface
Stress rib, the vibration generated on square stance, striking surface by be closed stress rib conduct, vibration along stress rib both ends around half-turn
Become the vibration of different directions, then meets and offset most vibrational energy.The vibration of striking surface is supported on being closed stress rib
Disappeared most vibration, reduces vibration and is transmitted at handle by golf club, to reduce vibration to golf sports
The interference of member.
Stress rib striking surface it is close-shaped include annular, ellipse, triangle, rectangular, polygon and irregularly
Annular.In the present embodiment, stress rib is in the close-shaped for annular of striking surface.
Stress rib thickness be 1-15mm, be highly 0.5-15mm, the distance between adjacent two stress rib is equal, two it is adjacent by
Power rib distance is 1-7mm.The selection of above-mentioned data is that the experiment based on technical staff obtains, the batting in this data area
Face makes more excellent in square stance balling effect.Specific more excellent aspect is to be embodied in square stance, the elastic limit of golf club head
Higher, the elastic kinetic energy ratio that can be converted to golf of square stance is larger, and golf acquisition instantaneous kinetic energy is larger, flight
Farther out, in addition to this, striking surface within the above range can generate frictional force, and the size of its frictional force can prevent square stance
Slipping phenomenon occurs for golf, and can in-fighting of the relatively low golf club head to kinetic energy to greatest extent.The weight of golf club head
Amount can also be adjusted by the thickness of stress rib and height, according to different golf weight requirements, produce different-thickness or
The stress rib striking surface of height is arranged in pairs or groups with golf club head, can save the program of additional adjustment counterweight.The distance between stress rib
Equal, the friction coefficient of generation is equal, can prevent golf from skidding.
It is what non-crystaline amorphous metal golf club head was made that the structure design of above-mentioned striking surface, which is all based on golf club head, but
The structure design of striking surface is not intended to limit in the present invention to be made in non-crystaline amorphous metal golf club head, equally can be stainless
It is made on the golf club head of the other materials such as steel, titanium alloy, aluminium alloy.Non-crystaline amorphous metal has preferable mouldability and injection molding
Property, it can preferably realize the striking face structure design of the present invention.The structure and size and spacing distance of stress rib on striking surface are all
