DETAILED DESCRIPTION

(6) The concept, the specific structure, and the technical effects of the disclosure will be clearly and completely described below with reference to the embodiments, to fully understand the objectives, features, and effects of the disclosure. Apparently, the described embodiments are only some embodiments of the disclosure, rather than all of the embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the disclosure without creative efforts shall fall within the protection scope of the disclosure. In addition, all coupling/connection relationships involved in the patent application do not mean that components are directly connected only, but also mean that a coupling accessory may be added or reduced based on a specific implementation status, to form a better coupling structure. Various technical features of the disclosure can be mutually combined in the case of no conflict.

Embodiment 1

(7) A method for manufacturing a golf putter head includes a forging step, a solution treatment step, and a quenching treatment step of a head body. The steps are specifically as follows:

(8) (1) Manufacturing of the Head Body:

(9) FIG. 3 is a schematic view of a head body of a golf putter head according to an embodiment of the disclosure. A 303 stainless steel bar is selected and is sequentially subjected to rough forging, medium forging, and fine forging at a temperature of 800-1000° C., to obtain a head body. The head body has a shape shown in FIG. 1. In other words, the head body includes a vertical ball hitting panel portion 2 and a rod body 1 located at a corner of a top surface of the head body. The ball hitting panel portion 2 is a vertical plane, and the rod body 1 is used to connect to the putter, so that a user holds the putter with hands and hits a ball. The top surface 3 of the head body is of a shape of an approximately rounded rectangle. The ball hitting panel portion 2 is provided with a heel portion 21 adjacent to the rod body 1, a toe portion 22 located opposite the heel portion 21 and away from the rod body 1, and a middle portion located between the heel portion 21 and the toe portion 22.

(10) (2) Solution Treatment:

(11) The head body manufactured in step 1 is heated in a vacuum furnace body to 1040° C. and then heat preservation treatment is conducted for 3 hours. After temperature in the furnace body is lowered to 300° C., nitrogen is introduced to the vacuum furnace for rapid cooling to a normal temperature and then the head body is taken out.

(12) (3) Quenching Treatment:

(13) High-frequency treatment is conducted on the toe portion 22 and the heel portion 21 at 1040° C. for 6 seconds. After the treatment is completed, the toe portion 22 and the heel portion 21 may be rapidly cooled for 5-30 seconds through spraying using a sprayer. Water or oil at 5-40° C., or other fluid having a relatively low temperature, may be sprayed.

(14) Through the foregoing steps, a putter head with hardness gradually increasing from the middle portion of the ball hitting panel at which the hardness is relatively low to either side of the ball hitting panel at which the hardness is relatively high, as required in the disclosure, can be obtained. After a suitable putter is assembled on the rod body 1, a golf putter with high stability and fault tolerance is obtained.

Embodiment 2

(15) There is provided a method for manufacturing a golf putter head which is different from Embodiment 1 in that the head body of the putter is made of 304 stainless steel. FIG. 4 is a schematic view of a golf putter head according to another embodiment of the disclosure. As shown in FIG. 2, during manufacturing of a head body, the head body is manufactured into a semi-cylindrical shape. In other words, the golf putter head body has a top surface 3 of semi-circular shape, and a side face including a rectangular ball hitting panel portion 2 and a cambered surface.

Embodiment 3

(16) There is provided a method for manufacturing a golf putter head which is different from Embodiment 1 in that the head body of the putter is made of carbon steel. The putter head is subjected to heat preservation treatment at a temperature of about 750° C. for 3 hours, and water at a room temperature is directly sprayed for 30 seconds for rapid cooling and quenching.

Embodiment 4

(17) There is provided a golf putter head which is different from Embodiment 1 in that the head body of the putter is made of spring steel, and the head body is a flat triangular prism and is quenched at 1000° C.

Embodiment 5

(18) There is provided a golf putter head which is different from Embodiment 1 in that the head body is of a strip shape.

Embodiment 6

(19) There is provided a golf putter head which is different from Embodiment 1 in that the top surface of the head body is of a shape of trapezoidal or inversely trapezoidal quadrangular prism.

Embodiment 7

(20) There is provided a golf putter head which is different from Embodiment 1 in that the top surface of the head body is of a fork shape.

Embodiment 8

(21) Comparative Test

(22) The golf putter heads manufactured in Embodiments 1-3 are used to obtain golf putters, and three commercially available golf putters (PING Oslo, TaylorMade Spider Tour, and Odyssey works #1) are used as reference examples 1-3 to conduct comparative tests to test data of a ball speed, a conversion rate, and a conversion rate decline rate when the putters hit a golf ball at a putting green speed of 8 and a club speed of 3.65±0.04 mph. Multiple groups of repeated tests are conducted, and results are shown in the following table:

(23) Many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood within the scope of the appended claims the invention may be protected otherwise than as specifically described.

(24) TABLE-US-00001 TABLE 1 Comparative test results Embodiment Embodiment Embodiment Reference Reference Reference 1 2 3 example 1 example 2 example 3 Club speed 3.65 ± 0.04 Ball speed 1 6.01 ± 0.02 6.11 ± 0.06 5.83 ± 0.07 5.95 ± 0.01 5.51 ± 0.01 5.73 ± 0.01 Conversion 1.64 ± 0.06 1.67 ± 0.03 1.59 ± 0.07 1.63 ± 0.03 1.51 ± 0.05 1.57 ± 0.04 rate 1 Ball speed 2 6.02 ± 0.02 6.13 ± 0.02 5.87 ± 0.06 6.23 ± 0.08 5.90 ± 0.07 6.05 ± 0.09 Conversion 1.65 ± 0.03 1.68 ± 0.06 1.61 ± 0.03 1.72 ± 0.03 1.63 ± 0.03 1.64 ± 0.02 rate 2 Conversion 0.007% 0.013% 0.015% 5% 7% 4% rate decline rate

(25) Wherein, the ball speed 1 is a ball speed when the ball is hit by a middle portion of a putter, a conversion rate 1 is a ratio of the ball speed 1 to the club speed, the ball speed 2 is a ball speed when the ball is hit by a toe portion or a heel portion of the putter, and a conversion rate 2 is a ratio of the ball speed 2 to the club speed. The conversion rate decline rate is equal to (conversion rate 1−conversion rate 2)/conversion rate 1×100%, and is used to characterize a difference between final movement distances of the ball when the ball is hit by different portions of the putter. When the decline rate is closer to 0, it indicates that a difference in a ball hitting portion of the putter has a smaller impact on movement of the ball, and fault tolerance of the putter is also better.

(26) As can be seen from the results in the foregoing table, the conversion rate decline rates of the existing products are at least 4%, and even reach 7%. For a 6-yard (20-foot) ball hitting distance, a final error may be as much as ±1 yard (3 feet). This is apparently unacceptable for golfers who are seeking for stability in performance and accurate ball control. The conversion rate decline rates of the golf putters manufactured in the embodiments during the test are almost zero. In other words, the movement distance of the ball is not changed regardless of whether the ball is hit by the middle portion, the toe portion, or the heel portion of the putter. No loss in the distance occurs when the ball is hit by different portions of the putter. The putters in the embodiments, when used to hit the ball, have higher stability and fault tolerance, so that the golfer can achieve precise ball control.

Embodiment 9

(27) There is provided a method for manufacturing a golf putter head which is different from Embodiment 1 in that the head body of the putter is made of titanium alloy.

(28) Preferred embodiments of the disclosure are specifically illustrated above, but the disclosure is not limited to the embodiments. Those skilled in the art may also make various equivalent modifications or replacements without departing from the scope of the disclosure, and these equivalent modifications or replacements shall all fall within the scope defined by the claims of the application.
