Problems solved by technology

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

Embodiment 1

[0032] Embodiment 1 A golf head manufacturing method specifically includes 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;

[0038] (6) ...

Embodiment 2

[0043] Embodiment 2 A method for manufacturing a golf head is basically the same as Embodiment 1, the difference lies in:

[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 repair method of an uneven surface in a golf head and a manufacturing method of the golf head. The repair method comprises the following steps that firstly, the golf head is cast with Ti alloy raw materials, the quantity of which is less than the normal quantity; the weight and the position which need to be repaired and filled at the later stage are determined; a matched ceramic die which is provided with a fitting surface is made of high-purity Al2O3; Ti-based amorphous brazing filler metals are laid in the position to be repaired, and the brazing filler metals are lightly extruded by the fitting surface of the ceramic die, so that the brazing filler metals can be uniformly filled in an uneven part to be repaired in the golf head; the relative positions of the ceramic die and the golf head are fixed, and then roasting is performed. According to the repair method, the selected Ti-based amorphous brazing filler metals and high-purity Al2O3 ceramics have unique non-bonding performance and excellent weld repairing performance; the weld bonding performance of the Ti-based amorphous the selected filler metals and Ti-based alloys is excellent, and the welding effect is good; the manufacturing method of the golf head has the advantages of simplicity, raw material saving, time saving, labor saving, high product quality and production efficiency and easiness in realization of large-scale production with 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 the number of strokes they hit. 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 level of performance. At present, due to the advantages of high s...
