FIG. 1 is a flow chart of a method of manufacturing a golf club head according to an embodiment of the present invention.
The achievement of the objects, functional features and advantages of the present invention will be further described with reference to the accompanying drawings, in conjunction with the embodiments.
Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below are exemplary and intended to illustrate the present invention and should not be construed as limiting the invention, and all other embodiments, based on the embodiments of the present invention, which may be obtained by persons of ordinary skill in the art without inventive effort, are within the scope of the present invention.
Referring to fig. 1, the method for manufacturing a golf club head according to the embodiment of the present invention includes the following steps:
1) A product mold is provided having a cavity adapted to a golf club head. When the mould is manufactured, the mould is required to be manufactured according to the design drawing and specification requirements of the golf club head so as to ensure that the mould can accurately copy a high-quality club head blank.
2) And adding a bonding agent into the powder base material to mix to form a prefabricated material, namely a step of mixing, wherein the powder base material is metal powder, alloy powder or metal compound powder. In this step, the binder is usually a material capable of binding the powder particles, for example, the binder may be selected from one or more of polyethylene, wax, polyurethane, and two-component epoxy. Different adhesive blending ratios and mixing time can be adjusted according to the characteristics of materials, so that the prefabricated materials are ensured to have proper fluidity and cohesiveness, segregation and impurities are not required in the mixing process, and the mixed materials are not agglomerated.
The adhesive is added into the metal powder, so that the high-strength property of the metal and the fluidity and plasticity of the adhesive are utilized, the strength and strength of the ball head can be improved, the product stress is improved, and the metal powder can keep the shape of a blank body after injection molding and degreasing extraction to form a non-smooth surface.
3) And injecting the prefabricated material into a cavity of the product die, and heating, pressurizing and solidifying to form a ball head blank, namely a 'press molding' step. When injecting the preform, it is necessary to ensure that the preform fills the entire cavity and is free of bubbles and voids. In the solidification process, the prefabricated material is melted and fills the whole cavity in a heating and pressurizing mode to form the shape of a ball head blank.
4) And sintering the ball head blank in high-temperature equipment to form a compact golf head, namely a sintering step.
In the step 4), the golf club head after the press forming is sintered in a high temperature device (a high temperature furnace or a vacuum furnace), and a series of physical and chemical reactions such as diffusion, recrystallization, fusion welding, chemical combination, dissolution and the like are carried out among powder particles in the sintering process, so that the material structure is strengthened to form specific mechanical properties. The metal powder is injection molded to a fully dense or nearly fully dense state by sintering. In the process, the sintering temperature needs to be controlled in a vacuum furnace, for example, the sintering temperature is controlled in the range of 1000-1400 ℃ according to different metal materials, so that cracks are avoided, and a high-density and high-strength metal piece is obtained.
It will be appreciated that the above steps 1) and 2) are not required in order, and are specifically selected according to the need.
According to the golf club head manufacturing method provided by the embodiment of the invention, the metal powder base material is fast in solidification speed, fine and uniform in crystal grains, the product performance is effectively ensured to be stable, and the strength and the play resistance of the product are improved, so that the golf club head performance is effectively improved. The golf club head manufactured by the method has no burrs and no criticizing front, can effectively improve the utilization rate of materials, furthest reduce the material loss and waste, effectively reduce the working procedures of post-processing treatment of the golf club head, reduce the production labor force, save the time and further reduce the production cost. In addition, the ball head can be suitable for manufacturing various special-shaped ball heads, and the variety of product types is enriched. In short, compared with the technology in the related art, the technology is simpler, has low technical threshold, low cost and high production efficiency, and can adapt to the manufacturing and processing of the golf club heads with various shapes while ensuring the performance of the golf club heads.
With continued reference to fig. 1, in one embodiment of the present invention, step 4) further includes, before sintering the ball end blank:
degreasing and extracting the ball head blank to remove the adhesive among powder particles at different positions on the ball head blank, namely a degreasing and extracting step. That is, the organic binder contained in the molded ball head preform is removed before sintering, and the binder is ensured to be gradually discharged from fine gaps among powder particles at different positions of the preform, so that the product strength is improved.
In particular, step 4) is to sinter the ball head blank, which is one of the important steps for preparing the ball head. However, the ball head blank also needs to be degreased and extracted before sintering. The fat treatment is to remove fat and grease on the surface of the ball head blank, and the degreasing treatment aims to remove pollutants, so that the surface of the ball head blank is cleaner, and the subsequent treatment is convenient.
The extraction treatment refers to removing the adhesive between powder particles at different positions on the ball head blank by using a chemical solvent or other methods. The adhesive is used for bonding powder particles together, so that the quality of the ball head is more uniform, and the density and strength of the ball head are improved. However, the adhesive may also negatively affect the performance of the ball head, and thus an extraction process is required to remove the excess adhesive.
It is understood that the degreasing method may be implemented by immersing in a solvent, or by a thermal decomposition method in which an organic substance is decomposed into an inorganic substance and a gas by using a high temperature. During the degreasing extraction process, fats and other organic matters may be decomposed and volatilized using a thermal decomposition method, thereby removing them. The method can avoid using chemical solvents or other harmful substances, so that the degreasing and extraction process is more environment-friendly, and the cleanliness of the surface of the ball head blank is higher.
Contaminants and redundant adhesives on the surface of the ball head blank can be removed through degreasing and extraction treatment, so that the ball head blank is purer, and the subsequent sintering treatment is facilitated. These steps can improve the quality and performance of the ball head and ensure the consistency of the ball head.
In one embodiment of the invention, the method further comprises:
and carrying out surface appearance treatment on the sintered golf club head. The surface appearance treatment comprises one or more of electroplating, phosphating and anodizing.
That is, in this embodiment, the golf club head manufactured by sintering is required to be subjected to surface appearance treatment to further improve its quality and appearance. The surface appearance treatment may include one or more of electroplating, phosphating, and anodizing.
Electroplating is a method for depositing metal ions on the surface of a material, and can improve the wear resistance, corrosion resistance and appearance quality of a ball head. Different metals, such as chromium, nickel, silver, gold, etc., can be selectively deposited on the ball surface for different effects.
Phosphating is a surface treatment method, and the mechanical property and corrosion resistance of the ball head are improved by forming a layer of phosphating film on the surface of the ball head. The phosphating film can improve the friction coefficient and the wear resistance of the material, and can also increase the surface hardness and the corrosion resistance of the material.
Anodizing is a method of forming an oxide film on the surface of a ball by an electrolytic reaction. The oxide film can improve the corrosion resistance of the ball head and improve the appearance quality and the friction coefficient.
The surface appearance treatment method can select one or more treatments according to actual needs so as to achieve the optimal effect. The surface appearance treatment may further enhance the quality and performance of the golf club head, making it more suitable for use in golf practice.
In one embodiment of the present invention, the injecting the preform into the cavity of the product mold and heating, pressurizing and curing to form a ball head blank includes:
and feeding and injecting the prefabricated material into a cavity of the product mold by a molding machine under the state of heating and plasticizing, and solidifying and molding to obtain a ball head blank.
And opening the die, taking out the ball head blank, and performing cooling treatment.
Wherein the heating temperature is 140 to 160 ℃, the pressure is 100 to 150kg, and the cooling temperature is 40 to 60 ℃.
That is, the process of preparing the ball head blank comprises injecting the prefabricated material into the cavity of the product mold, and heating, pressurizing and solidifying to form the ball head blank. Specifically, the prefabricated material is fed and injected into a cavity of a product mold by a molding machine under the state of heating and plasticizing, and is solidified and molded by the action of heating and pressurizing, so that a ball head blank is obtained.
In this process, the heating temperature is 140 to 160 ℃, which is to heat the preform to a plasticized state, making it easy to flow and fill into the cavity of the product mold. The heating temperature is selected in consideration of the material properties of the preform and the performance of the molding machine to ensure that the preform is sufficiently plasticized and filled into the mold cavity.
The pressure is 100 to 150kg in order to apply sufficient pressure in the heated state to enable the preform to fill the cavity and closely conform to the mold surface. The pressure is selected taking into account the material properties of the preform and the shape and size of the cavity to ensure that the preform fills sufficiently into the cavity and forms the shape of the ball end blank.
After the ball head blank is taken out by opening the die, cooling treatment is needed to solidify the ball head blank. The cooling temperature is 40 to 60 ℃, so that the temperature of the ball head blank is reduced to a temperature suitable for treatment, and deformation or cracking of the ball head blank is avoided. The length of the cooling time can be adjusted according to the material property of the prefabricated material and the size and shape of the ball head blank so as to ensure that the ball head blank can be completely solidified.
Through the preparation process, a golf club head blank with high quality can be prepared, and the guarantee is provided for subsequent treatment.
Preferably, the powder substrate is selected from one or more of iron-based alloy steel, stainless steel, nickel-based alloy, tungsten alloy and titanium alloy. Among the powder base materials, the iron-based alloy steel has higher strength and plasticity, the stainless steel has good corrosion resistance and mechanical property, the nickel-based alloy has high-temperature strength and corrosion resistance, the tungsten alloy has high hardness and wear resistance, the titanium alloy has higher strength and light weight, and the powder base materials are applied to the manufacture of golf heads, so that the golf heads are ensured to have reliable strength and play resistance, and have good application prospect.
The embodiment of the invention also provides a golf club head which is manufactured and formed by the method.
In summary, the present application provides a method for preparing a golf club head with high quality and a golf club head manufactured by the method. The method adopts a powder metallurgy process to prepare a powder substrate into a prefabricated material, and the prefabricated material is solidified and molded in a cavity of a product die by a heating and pressurizing method to finally obtain a ball head blank.
