Abstract

The utility model discloses a wood golf club head with a high strength structure. The wood golf club head comprises a bowl-shaped body, an upper cover body which is covered on the opening the body and a connecting pole which is near the corner of the inner edge of a ball hitting surface, and the front side of the bowl-shaped body forms the ball hitting surface. The body, the upper cover body and the connecting pole are connected via welding seams. The wood golf club head of the utility model has the advantages of firm structure, high strength, and difficult deformation and breakage.

Description

Wooden golf bulb with high-strength structure

Technical field

The utility model relates to the improvement of Wooden golf bulb intensity.

Background technology

The bar head of common golf clubs mainly contains three kinds on the market: the one, the mode moulding of employing die casting, this mode only limits to the aluminum alloy materials product, and aluminum alloy materials matter is soft, intensity difference; The 2nd, employing hot investment casting moulding, the Wooden golf bulb material structure density of being produced is not as good as precision forging, and the production cycle is long, the production cost height; The 3rd, stamping forming four are combined by welding, this club head weld seam connecting portion is many, easy deformation or break.

The patent No. is that 01201960.7 Chinese utility model patent discloses a kind of " having the welded golf driver head of improvement ", this golf driver head mainly comprises a bar head main body and a batting plate, this main body lacks nest from positive toward being recessed into one, make positive outer rim form a ring-type and connect face, this ring-type connects face and is provided with the storing groove that extends along rim, this batting plate is to be covered on bar head main body front, the ring-type of its back side and this bar head main body connects between the face, moisten to write and moisten and ooze the hard solder layer that after coagulation forms by being preset in hard solder fusion in this groove, having one on the bar head surface again along the ring-type weldering knot portion that seam is extended, is to be formed by the metal melting after coagulation.The Welding Structure of this improvement makes the batting plate combine more firmly with the bar head main body to a certain extent, but because the batting plate is main stress point, the weld seam around the striking plate is still the hidden danger of club head cracking; The casting of bar head main body forms, and material structure density is not enough.

The utility model content

The purpose of this utility model provides Wooden golf bulb a kind of high-strength structure, that be not easy to break.

For reaching above-mentioned purpose, the utility model adopts following technical scheme: this Wooden golf bulb is by being bowl-shape main body and covering the upper cover body at body openings place and form near the joint pin of striking surface inside edge corner, is connected by weld seam between main body and upper cover body and the joint pin three; Described bowl-shaped body comprises striking surface, skirt section and bottom three parts, and striking surface is in the front side of bowl-shaped body.

As preferred version, the wall thickness of described striking surface is 1.8mm～4.0mm, and the wall thickness of skirt section and bottom is 0.7mm～3.0mm; The wall thickness of upper cover body is 0.4mm～1.5mm.

Compared with prior art, because striking surface, bottom and the skirt section of the high-intensity Wooden golf bulb of the utility model have constituted bowl-shaped body jointly, be integrated between the each several part, there is not weld seam, so sound construction, can not break.Though be connected by weld seam between upper cover body and the main body, upper cover body is stressed less, is difficult for equally breaking.Bowl-shaped body and upper cover body can be passed through forging molding respectively, and material structure density height and processing cost are low.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described in detail.

Fig. 1 is the structural representation of rod bulb bowl-shaped body.

Fig. 2 is the structural representation of rod bulb.

The specific embodiment

As shown in Figure 1, bowl-shaped body 1 is by forging molding, and main body 1 front side forms the striking surface 11 that roughly is the plane.The processing of bowl-shaped body 1 can divide four-stage to finish: the phase I, with sheet material, insert in the drawing die greater than striking surface 11 thickness, and use hydraulic press to stretch and finish the thick embryo of club head; Second stage, the thick embryo of phase I gained is inserted in the forging mold, use the precision forging machine to forge in the forge hot mode, striking surface 11 and skirt section 12 unnecessary material are got into mould clout district after forging, to remain in the clout excision in mould clout district again, finish the wall thickness in striking surface 11 and skirt section 12, the preferred thickness of striking surface is 1.8mm～4.0mm, and the preferred wall thickness in skirt section is 0.7mm～3.0mm; Phase III, the thick embryo of finishing striking surface 11, skirt section 12 wall thickness is inserted in the reeded mould in bottom, use the precision forging machine to forge in the forge hot mode, the clout of bottom 13 is got in the groove of mold bottom after forging, again that the excision of the clout in groove mill is clean, finish the thickness of bottom 13, bottom 13 preferred wall thickness are 0.7mm～3.0mm; The quadravalence section is inserted the thick embryo of phase III gained in the finishing mold, uses the precision forging machine to forge in the warm forging mode, and the defective of thick embryo surface is eliminated, and the weight of control main body.The joint pin 3 that is used to connect club can be fixed on striking surface 11 inside corner places by welding or alternate manner.In addition, also by forging molding, the preferred wall thickness of upper cover body 2 is 0.4mm～1.5mm to upper cover body.At last upper cover body 2 is covered main body 1 opening part, by being welded and fused, as shown in Figure 2.Because striking surface 11 is integrated with main body 1, square stance is subjected to bigger power and also can break, and sound construction is durable in use.

Claims
