Abstract
A method for manufacturing a golf club head with sole textures comprises steps of providing and bending a crude rod made of a metallic material, a first forging process for forming a uniaxial tilting blank of a head body via a first forging die, a second forging process for forming a biaxial tilting blank of the head body via a second forging die, and a third forging process for forming a club head with sole textures via a third die. Compared with machining grooves to a sole of the club head, the method is time efficient and cost effective.
Claims6
A method for manufacturing a golf club head with sole textures by precision forging, the method comprising steps of:
- providing and bending a crude rod made of a metallic material;
- a first forging process for forming a uniaxial tilting blank of a head body of a golf club head, wherein the crude rod being bent is placed in a first forging die of a forging machine and is forged by a single forging press or a multi-forging press to form the uniaxial tilting blank of the head body;
- a second forging process for forming a biaxial tilting blank of the head body, wherein the uniaxial tilting blank of the head body is placed in a second forging die of the forging machine and is forged by a single forging press or a multi-forging press to form the biaxial tilting blank of the head body;
- a third forging process for forming a club head with sole textures, wherein the biaxial tilting blank of the head body is placed in a third forging die of the forging machine and is forged by a single forging press or a multi-forging press to form the club head having a biaxial tilting striking face and sole textures formed at a sole of the club head, wherein
- in the first forging process for forming a uniaxial tilting blank of a head body, the uniaxial tilting blank has a blank base having a blank face and a first datum plane being parallel to the blank face, a first axis and a second axis are perpendicular to each other and are defined in a reference datum of the forging machine, a first inclined angle is formed between the first datum plane and the first axis and ranges from 3 degrees to 25 degrees, and a second inclined angle is formed between the first datum plane and the second axis and is 0 degree;
- and
- in the step of the second forging process for forming a biaxial tilting blank of a head body, the biaxial tilting blank of the head body has a head base including a striking panel with a striking face, a sole is located behind a lower part of the striking panel, and a second datum plane is parallel to the striking face;
- a first inclined angle is formed between the second datum plane and the first axis defined in the reference datum and ranges from 3 degrees to 25 degrees, and a second inclined angle is formed between the second datum plane and the second axis defined in the reference datum and is perpendicular to the first axis and ranges from 3 degrees to 28 degrees.
