TW537918B - Method for making a golf putter head of a stone and the golf putter head made thereby - Google Patents

Abstract

A method is designed for making a stone putter head. The method includes a first step in which a stone material having a hardness under HRC 6 is selected. The specific gravity of the stone material is measured and recorded. The stone material is then cut into a plurality of blanks, which are then provided on one planar surface thereof with a mold plate corresponding in size to the putter head. The profile of a ball-striking face is drawn on the blanks by using the mold plate before the blanks are ground such that the grinding is started from the outer portion of the profile. Thereafter, a detailed grinding is carried out in accordance with a three-dimensional standard putter model which is used as a reference blueprint of the detailed grinding. The ball-striking face is subsequently provided with a slot, a metal weight inlaid in the slot, and a soft ball-striking face plate attached to the outer layer of the metal weight.

Description

537918 V. Description of the invention (1) The present invention relates to a golf ball putter head manufacturing method with a stone golf ball (P \ ^ Μ). Features have a higher quality than metallic materials = ^ 3; the head has a higher quality regardless of the production process or use conditions: ί ;: Push A according to A f person: t 'Shang Fu can be roughly divided into wooden clubs Furnace β 21 Among them, the putter is a special two iron cup for putting the ball into the hole and two = put + dry. Most of them are used on the green (Green t charm, so one is used, so every The last one, two, or three of a hole: The moment-throwing ball 225 enables the golf ball to move toward the expected S3 with a putter ^ ^ into the hole (hole / cup), so in order to reach the ball 1 and the path And to overcome the limitations of the putter head's volume and weight, it is necessary to accurately enter the hole and use a weight block to change the center of gravity of the club head (pushing distance) to effectively improve the two balls = dagger to f : The head structure of the conventional putter is the purpose of using the heart to configure two different lighter metal materials, and the weight of the weight; =乂 Made of large metal materials. Injury is achieved by the specific gravity of the metal material to effectively change the center of gravity ▼ Although the traditional putter head can theoretically use this method =, so: 2 ΐ 'but ignore two Gold with different specific weights; the material size varies greatly from 1 to 1. The conventional weight block and the main head of the club are used for their thermal fit (nterference fit). One.

Page 5 537918 V. Description of the invention (2) The requirement of dimensional limitation, after assembly, the tightness is often maintained in the fitting space), and it is directly embedded into the internal structure of the head body after assembly, which promotes the two. It is tightly combined into one body without any gap, so that when there is a large temperature change, the head body and the weight block will have various physical states such as expansion and contraction due to their different thermal expansion coefficients, so that In the case of simultaneous expansion and contraction, such as expansion or contraction, there are various unexpected damages in the internal structure of the club head, such as distortion or fracture of the metal lattice and residual stress, etc. These unpredictable damages not only seriously affect the stability of the center of gravity of the club head, but also cause the club head to lose its original accuracy and quality due to the change of the LD value. The main object of the present invention is to provide a "manufacturing method for making a stone golf putter head", which uses the stone itself to have a low thermal expansion coefficient and a thermal conductivity coefficient, so that the putter head is subjected to various temperature changes. It can effectively block the external temperature from being transmitted to the weight block, so that the weight block can be kept in a stable state in the internal structure of the club head, thereby effectively overcoming various conventional club heads due to temperature changes. Stress damage, which makes the overall structure and quality of the putter head more stable. Another object of the present invention is to provide a "manufacturing method for manufacturing a stone golf putter head". The finished product obtained through the manufacturing method has an extremely stable internal structure, which can keep the center of gravity of the putter head to a certain level. In the position, the LD value is not affected by the change of external temperature, which can ensure that the LD value of the putter head is unchanged. The disadvantages of the conventional putter that gradually loses its accuracy due to internal structure changes after long-term use are completely eliminated. .

Description of the invention (3) As for the other purposes and features of this manufacturing method, detailed implementation steps and diagrams are given in the following, for those who are familiar with the art to further understand. Description of drawing number: 1 0-main body 1 1-striking surface 12-groove 20-metal weight block 3 0-striking panel Please refer to the first figure, the present invention is a method for manufacturing a stone golf putter head The steps include: 1. Select the stone whose hardness value is below HRC 6 and measure the specific gravity of the stone and record it for use as the reference value for the metal weight when the finished product is completed (for each The texture of the batch of stone material has different internal tissue density, so the specific gravity values will not all be the same and will be different, so it must be recorded) 2. Cutting the stone into several small rough embryos with a water knife, The volume of the rough embryo body is about 5% to 10% larger than the volume of the finished product. 3. Draw a contour of the outer edge of the striking surface on the rough embryo, and have a size equal to the striking surface of the putter head. The same shape template is attached to one of the planes of the rough embryo, and then the template is used to draw the contour shape of the outer edge of the striking surface on the rough embryo; 4. The first grinding process is formed from the stroke The exterior of the face contour shape began to be studied , Until coincide with the outline to the face contour; V. second grinding molding, take a three-dimensional model as a reference standard ram detailed blueprint for polishing, so that all the three-dimensional external shape of a standard push
