Method for making golf head

Abstract

A method for making golf head mainly includes that the head is divided into a front half part and a rear half part and the two parts are respectively formed; after the front half part in high pressurearea the batter side and the side of which are jointed with the rod body, grinding and expulsion coefficient testing are carried out, and the expulsion coefficient is adjusted by utilizing fin therein, material thickness, material strength and the like, so that the expulsion coefficient of the front half part meets design value; the front half part is jointed with the rear half part to be formed,so that tolerance of expulsion coefficient of head finished product and design value approaches minimum, thus the characteristics of the head are improved and the aim of meeting the expulsion coefficient standard of golf association is achieved.

Description

【Technical field】 [0001] The present invention relates to a manufacturing method of a golf head, in particular to a manufacturing method that can minimize the reflex coefficient of the finished ball head and the design tolerance, so as to improve the yield of the finished ball head and reduce the manufacturing cost and Improve competitiveness. 【Background technique】 [0002] Because golf has the dual effects of sports, fitness and communication, it continues to attract more people to participate in this sport, which also prompts golf equipment manufacturers to actively develop better products to increase consumers' desire to buy. The development of materials and the improvement of technology have increased the effect of golf club swings. For players with the same level of hitting skills, players who use clubs with better functions can naturally achieve better results. This situation will obviously have an unfair impact on the game.

[0002] Because golf has the dual effects of sports, fitness and communication, it continues to attract more people to participate in this sport, which also prompts golf equipment manufacturers to actively develop better products to increase consumers' desire to buy. The development of materials and the improvement of technology have increased the effect of golf club swings. For players with the same level of hitting skills, players who use clubs with better functions can naturally achieve better results. This situation will obviously have an unfair impact on the game. In terms of the reflex coefficient of the ball head, the current coefficient is limited to a CT value below 257, and the clubs sold in the market will be tested. The current benchmark is After the test, if 5 of the 16 clubs exceed the standard, the club product must be removed from the shelves, and the regulations will be more stringent in 2010. If 2 of the 16 club products fail to meet the standard, the club product Club products must be taken off the shelf, and the current industry's practice of controlling the recoil coefficient when manufacturing ball heads is to calculate the recoil coefficient values ​​​​of each component of each ball head in advance according to the material used, and then cast them accordingly. Or combine the forging method to form the ball head, and finally grind the entire ball head. Although this pre-calculated method can produce the finished ball head, due to various factors in the manufacturing process, there will be various factors that will affect the finished ball head. , so the general design value will be set at 245±12, that is, let the preset reflex coefficient be lower than the specified upper limit value, and then grind the striking surface after molding to make it closer to the upper limit value. , most of the ball head products produced cannot meet the pre-designed anti-reflex coefficient requirements. In addition to the ball end products that are not as good as they are, some ball end products may also have a reflex coefficient that exceeds the specified upper limit. At this time, the ball head with a low rebound coefficient can be improved to the specified upper limit by grinding the striking surface, but the finished product that exceeds the standard cannot be corrected at all, and it becomes a defective finished product that exceeds the specification. Although these finished products The crackdown effect is better, but it cannot be sold on the market, so as to avoid the consequences of being seized due to violations of regulations and causing all products to be removed from the shelves, they can only be scrapped as defective products, resulting in an increase in manufacturing costs and a corresponding decrease in profitability. It also lowers the competitiveness of products. No company has been able to come up with an effective solution to this situation.
