Problems solved by technology

[0004] The existing production method of golf head (mass about 200g) is to first cast an overweight ball with a weight 1g~5g more than the required raw material weight, and then remove the excess weight by grinding. However, Ti alloy itself has high strength. , The characteristics of high hardness make the process of removing excess weight very troublesome, not only time-consuming and laborious, but also a waste of precious Ti alloy raw materials, and the failure rate of products produced in this way is as high as 20%, the production efficiency is low, and the production cost high

Embodiment 1

[0032] Embodiment 1 A method for manufacturing a golf head, specifically comprising the following steps:

[0033] (1) First prepare the golf head with the Ti alloy raw material less than the normal amount of 1-2g according to the conventional investment casting method;

[0034] (2) Measure the actual weight of the golf head, and determine the weight that is expected to be added later according to the difference between the theoretical weight and the actual weight;

[0035] (3) Select the uneven and thinner part as the part to be repaired by measuring the golf head;

[0036] (4) Al with a purity of 99.9% and a grain size of 1 μm 2 o 3 Make a ceramic mold for the raw material with a fitting surface that matches the shape of the curved surface of the golf head to be repaired;

[0037] (5) Grind the part of the golf head to be repaired with sandpaper, and then clean it with acetone, so as to facilitate the better combination of Ti-based amorphous solder and the ball head;

Embodiment 2

[0043] Embodiment 2 A golf head manufacturing method, which is basically the same as Embodiment 1, the difference is:

[0044]In the above step (8), a plurality of fixed ceramic molds and golf heads are first placed on the disk of the batch rack and fixed, and then put into an oven or a roasting furnace for batch roasting. The batch rack consists of The support shaft, the base and a certain number of discs are installed on the support shaft, and the lower end of the support shaft is fixed on the base, see image 3 .

Abstract

The invention relates to a method for repairing uneven surfaces inside a golf head and a method for manufacturing the golf head. First cast the golf head with less than the normal amount of Ti alloy raw material, determine the weight and position to be filled after determining the need, make a matching ceramic mold with a fitting surface with high-purity Al2O3, and lay Ti-based amorphous on the part to be repaired For brazing material, use the mating surface of the ceramic mold to gently squeeze the brazing material so that the brazing material can evenly fill the uneven part to be repaired in the golf ball, fix the relative position of the ceramic mold and the golf head, and then bake it. The Ti-based amorphous solder and high-purity Al2O3 ceramics selected by the present invention have unique non-adhesive properties and excellent welding repair performance; while the Ti-based amorphous solder and Ti-based alloy have excellent welding adhesion and good welding effect; golf The manufacturing method of the ball head is simple, saves raw materials, saves time and labor, has high product quality and high production efficiency, and is easy to realize large-scale production at low cost.

Description

technical field [0001] The invention relates to the field of preparation of sports equipment, in particular to a method for repairing uneven surfaces inside a golf head and a method for manufacturing the golf head. Background technique [0002] Golf is one of the world's three famous gentlemen's sports, and the enthusiasm for golf in various countries is also very high. At the same time golf is considered to be one of the most material-influenced sports. Golf equipment is an important tool for players to exert their abilities. For golf equipment, its most important and simplest requirement is to help golfers reduce their strokes. In order to further achieve this goal, it is necessary to improve golf equipment. Accurately engineered equipment means precisely engineered clubs. One of the basis for a golfer to choose a club is the sound of hitting through the golf head. As an indispensable golf head in golf, its weight has a great influence on the sound of hitting and the le...
