Description

golf club head

technical field

The utility model belongs to golf equipment components, in particular to a golf club head.

Background technique

As shown in Fig. 1, the club head 10' of a conventional golf club is integrally formed by casting iron-manganese-aluminum alloy. Its thickness is usually greater than 5mm, and its front side forms a batting panel 101', its side extends to form a sleeve neck 102', its bottom surface has a chamber 103' for combining a counterweight 20', and its back is recessed to make the batting panel 101' has an opening of an elastic deformation space.

The club head 10' is casted with iron-manganese-aluminum alloy, which can have the excellent characteristics of iron-manganese-aluminum alloy, such as low specific gravity, good shock absorption, high heterogeneity weldability, high elastic coefficient and appropriate strength, so as to further reduce the center of gravity position and improve impact. Improve ball performance, increase the strength of heterogeneous welding, and expand the volume of the club head 10' and the hitting area.

Even so, when iron-manganese-aluminum alloy is actually used to manufacture the club head 10', the mold flow properties based on iron-manganese-aluminum alloy are not good, the casting properties are low, the thickness of the club head 10' changes, and the three-dimensional shape is too complicated. Factors, casting defects such as cold joints, slag holes and shrinkage cavities are often easily formed during casting of the cast product of the club head 10 ′. Usually, the above-mentioned defects of cold connection and slag inclusion can be overcome by improving the casting technology layer and properly controlling the casting runner system. Shrinkage cavity defects can be overcome by reserving processing allowance and grinding and repairing. However, when the shrinkage cavity defect is formed in the complex shape of the club head 10' and the uneven thickness of the section, such as the dimple or the hook corner, the shrinkage cavity defect is often difficult to repair, and as a result, the casting of the club head 10' is reduced due to the shrinkage cavity defect. Yield, and limit the application value of iron-manganese-aluminum alloy, thus become the biggest bottleneck of iron-manganese-aluminum alloy casting golf club head. On the other hand, although the center of gravity of the club head 10' can be adjusted by using the counterweight 20', it is still limited by the insufficient space of the chamber 103' for the club head 10', which also makes it impossible to effectively lower the overall center of gravity of the club head 10' Location. Therefore, there is a real need to further improve the conventional golf club head structure so that it is suitable for the casting process of low castability metals.

Detailed ways

As shown in Fig. 2 and Fig. 3 , the golf club head 10 of the present invention includes a ball striking panel body 10a and a weight body 10b.

The face plate body 10 a constitutes the front half of the golf club head 10 , and the face plate 11 and collar 12 are integrally formed therein. The batting face plate body 10a is preferably made of low castability metal such as iron manganese aluminum alloy. The thickness of the batting panel 11 of the batting panel body 10a is preferably less than 5mm, and the thickness variation value of the smaller thickness/larger thickness of any two adjacent parts of the batting panel body 10a is preferably maintained between 0.56 and 1 . Meanwhile, when the ball striking panel body 10a is cast by a mold, the cavity of the casting mold has the same predetermined shape and meat thickness variation design of the same ball striking panel body 10a. Thereby, when the molten iron of low castability metals such as iron, manganese and aluminum alloys is poured into the cavity of the mold, the molten iron of low castability metal can smoothly pass through any thickness change area of the cavity of the mold. That is to say, due to the proper control of the change value of the meat thickness, the utility model can improve the molten iron mold flow properties of low castability metals, thereby reducing the probability of shrinkage cavities in casting, so that the casting quality of the golf club head 10 can be relatively improved and The yield rate of the finished product is improved, and the utility model has excellent characteristics such as low specific gravity (6.8g/cm ³ ), good shock absorption, high heterogeneous weldability, high elastic coefficient and appropriate strength of iron-manganese-aluminum alloy.

As shown in FIG. 2 and FIG. 3 , the weight body 10 b constitutes the rear half of the golf club head 10 , and usually forms at least one opening 13 so that the ball striking panel 11 has room for elastic variation. The weight body 10b is made of a metal material with high specific gravity (about 10.0g/cm ³ ), which is preferably made of tungsten alloy or tungsten-iron-nickel alloy. The weight of the counterweight body 10b is greater than the weight of the ball striking panel body 10a, and the weight of the lower half of the counterweight body 10b is also greater than the weight of the upper half, whereby the counterweight body 10b can be used to greatly adjust and lower the overall center of gravity of the golf club head 10 , to improve hitting performance and increase hitting distance. Furthermore, the counterweight body 10b can be selected to use metal or alloy materials with different specific gravity according to product requirements, such as stainless steel, low carbon steel, alloy steel or special steel and other materials, therefore, the center of gravity adjustment design margin of the golf club head 10 can be increased. .

As shown in Fig. 4 and Fig. 5, since the thickness of the batting panel body 10a is relatively thin, the utility model preferably uses a welding method to combine the batting panel body 10a and the counterweight body 10b, and at the same time avoids the use of press fit. The ball striking panel body 10a and the counterweight body 10b are combined in a designed manner to prevent deformation or cracking of the ball striking panel body 10a during assembly. When welding, the utility model preferably uses high-nickel electrodes and a welding current of 100A to 150A for welding, so as to further increase the bonding strength, quality and yield of welding between dissimilar metals. Furthermore, the welding method can also be selected to use argon welding, brazing, laser welding, plasma arc welding or ion beam welding according to requirements. After welding, the ball striking panel body 10a and the weight body 10b are combined into the golf club head 10, and a weld bead 14 is preliminarily formed at the joint position of the two. Next, after proper surface processing, such as grinding and polishing the weld bead 14, the finished golf club head 10 can be produced. Furthermore, a processing margin can be reserved in advance at the combined position of the ball striking panel body 10a and the counterweight body 10b to utilize the above-mentioned surface processing.

As mentioned above, compared with the conventional golf club head 10', which is easy to produce shrinkage cavities when it is cast with iron-manganese-aluminum alloy, and it is difficult to greatly adjust the center of gravity, the utility model can indeed use the ball striking panel body 10a Combined with the weight body 10b, it not only has the excellent characteristics of high shock absorption of iron-manganese-aluminum alloy, but also can effectively reduce shrinkage cavity, so it has the effect of improving casting quality, product yield and center of gravity adjustment margin.
