Golf club head

Abstract

The invention relates to a golf club shaft head, comprising a front side casing piece and a rear side casing piece combined with the front side casing piece forming a shaft head casing. Formed by alloy, or Maraging steel, or stainless steel or other metals with good elasticity, the front side casing piece is equipped with a striking surface, an annular dish part extends backwards from the striking surface, the whole dish part is of cup shape, a scarf part is arranged at the outer end of the dish part, and the distance between the striking surface and the outer end of the dish part is equal to or larger than 8 centimeters, while the thickness of the dish part is equal to or less than 2 centimeters; formed by magnesium alloy, or aluminum alloy, or other lightweight metals with relatively light specific gravity, the whole rear side casing piece is of deep cup shape, and a scarf part is arranged at the margin of an open end of the rear side casing piece for scarf connection with the scarf part of the front side casing piece; a neck of the casing of the shaft head is arranged on the rear side casing piece. The invention has the advantages that the invention can be used merely after the front side casing piece is jointed with the rear side casing piece with epoxy resin, the casing pieces are free from breakage and falling off, and the problems of insufficient weld strength and bad jointing effect are solved.

Description

technical field [0001] The present invention relates to a golf club head, in particular to a golf club head using a light alloy such as magnesium or aluminum as a shell. Background technique [0002] The golf club head shell formed by light alloy such as magnesium or aluminum has the advantages of light weight, and it is easy to design a super large and low center of gravity club head, especially the magnesium alloy has good shock absorption, as the club head shell has its own its advantages. However, the strength of magnesium alloy is poor, so it is not suitable as a hitting surface. Therefore, the hitting surface must be made of a material with good elasticity such as titanium alloy or stainless steel. However, the melting point of magnesium or aluminum alloy is low, so titanium alloy or stainless steel The hitting surface of the ball cannot be joined with the shell of magnesium or aluminum alloy by brazing, nor can it be joined by general welding. Because the materials o...

Problems solved by technology

However, the strength of magnesium alloy is poor, so it is not suitable as a hitting surface. Therefore, the hitting surface must be made of a material with good elasticity such as titanium alloy or stainless steel. However, the melting point of magnesium or aluminum alloy is low, so titanium alloy or stainless steel The hitting surface of the ball cannot be brazed with the magnesium or aluminum alloy shell, nor can it be joined by general welding. Due to the different materials of the two, the strength of the welded joint is insufficient and the joint effect is poor.
