Abstract

The utility model relates to a head of a golf ball, which is made of forging titanium alloy and is formed by welding two sheets. The utility model is formed by welding a lower body and an upper cover integrally, wherein, the lower body is a cambered cavity body, the front surface of the lower body is a hitting surface of the head of a golf ball, and the upper cover is a cambered cover body matching with the edge of the upper opening of the cambered cavity body. The hitting surface of the head of a golf ball, which is arranged on the front surface of the lower body of the utility model, is a surface with a thin upper part and a thick lower part and is a conical surface. In general, the thickness of the upper is 3.4 mm, and the thickness of the lower part is 4.5 mm. An included angle between the bottom of the lower body of the head of a golf ball and the hitting surface is 80 DEG. The utility model which is designed according to the use requirements of the heads of gold balls improves the service life of the heads of golf balls and ball hitting accuracy. The thicknesses of the materials of the positions of the head of a golf ball of the utility model are different. The utility model which has the advantage of light weight is formed by the combination of two sheets. The welding boundaries of the utility model are least.

Description

Two-piece type forges titanium alloy golf club head

The utility model relates to the forging titanium alloy golf club head that a kind of two-piece type is welded.

Golf club in the market, how to make by stainless steel or other metal material, making bulb with titanium alloy material is employed just gradually, but make bulb with titanium alloy, be with forging type production mostly, and casting production is cast and is easy to generate defectives such as crackle, pore, oxidation because the titanium alloy of fusion is mobile poor, its internal material tissue looseness makes the strike intensity of bulb low, the life-span is limited, production cost is high.As use instead to forge to produce and then can avoid above-mentioned defective.Strike intensity improves a lot, and fabrication schedule is also simple than casting, and corresponding production cost reduces, and production efficiency improves, and favored by market so forge golf club.But there is the problem of moulding difficulty in forged titanium alloy bulb.So most factories make three to five chips to bulb, this bulb welding interface is many easily to produce the sweating heat distortion, and assembles difficulty, and the weld seam of weld, the particularly scope of attack ftractures easily.

The purpose of this utility model is exactly in order to address the above problem, provide a kind of two-piece type to forge titanium alloy golf club head, it is by some technical measures and rational mould structure, under the principle that guarantees forging molding, adopt the two-piece type structure, welding interface is minimized.

Technical solution of the present utility model:

A kind of two-piece type forges titanium alloy golf club head, it is characterized in that it is formed by lower body and two integral solder of loam cake, and lower body is an arc cavity body, and its front surface is the bulb scope of attack, and loam cake is the arc lid that matches with arc cavity body edge suitable for reading.Body front surface bulb scope of attack upper-thin-lower-thick down of the present utility model is the conical surface, and top thickness is 3.4 millimeters usually, and bottom thickness is 4.5, and the angle between the bulb lower body bottom and the scope of attack is 80 degree.

The utility model is the instructions for use according to golf club, has designed on the scope of attack thin and with the bottom certain angle is arranged, and improves service life and batting precision like this.Golf club of the present utility model, its characteristic is to use titanium alloy bar, after electric furnace is heated, in operations such as polishing, groove, polishings, promptly gets complete bulb.Its each position expects that thick difference, in light weight, two combinations, welding interface are minimum.Golf club of the present utility model, it is thick that its characteristic is to hit lining, and it is tapered that upper-thin-lower-thick becomes, and the scope of attack and bottom surface are 80 degree angles.It has following effect:

1, bond strength is good: because of the utility model bulb is to constitute with loam cake and two welding of lower body, welding interface is minimum, needs weld interval short, can be because of the welding temperature rise does not produce thermal deformation and thermal stress, and size more easily guarantees, can obtain high-quality bulb.

2, pass through some technical measures in the forging,,, reach the weight unanimity with chemical attack correction weight as using the anti-oxidation of pyroceram lubricant.

3, the bottom surface and the scope of attack are 80 ° of angles, scope of attack wall thickness upper-thin-lower-thick, and the intensity of the increase scope of attack is convenient to the user and is grasped the batting center of gravity, increases the stability of batting, and the power of guaranteeing to bat reaches more accurate balling effect.

4, forged titanium alloy bulb can avoid casting the many disadvantages of generation, and manufacturing process is simple, invest low, the production efficiency height.

5, forge after, by welding, polishing, polishing, scope of attack groove promptly obtain a kind of in light weight, outward appearance is beautiful, the golf club of long service life.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is an overall structure schematic diagram of the present utility model.

Fig. 2 is a decomposition texture schematic diagram of the present utility model.

Fig. 3 is the A-A directional profile schematic diagram of Fig. 2.

As Fig. 1-3, the utility model is formed by lower body 1 and 2 two integral solder of loam cake, and lower body 1 is an arc cavity body, and its front surface is the bulb scope of attack 3, and loam cake 2 is the arc lid that matches with arc cavity body edge suitable for reading.The lower body 1 front surface bulb scope of attack 3 upper-thin-lower-thicks of the present utility model are the conical surface, and top thickness is 3.4 millimeters usually, and bottom thickness is 4.5, and the angle between bulb lower body 1 bottom and the scope of attack 3 is 80 degree.
