Abstract
The invention relates to a batting panel with a two-layer powder metallurgy structure for a golf club head and a method for manufacturing the same. The batting panel has the two-layer powder metallurgy structure which is formed by combining a hard alloy layer made of alloy metal powders with stronger rigidity and a soft alloy layer made of alloy metal powders with weaker rigidity. When the batting panel collides with a ball body, the hard alloy layer can provide the batting panel with strength and bounce necessary for batting, while the soft alloy layer can absorb shock energy generated in batting so that the batting panel can maintain the original prior strength and bounce in batting and has the effect of absorbing shock. Besides, the two-layer structured batting panel cannot be separated and loosened by colliding with the ball body for a long time, thus the service life of the golf club head is prolonged. Besides, parent materials of the two alloy layers are the same as materials of a ball head main body so that a ball head finished product can be finished through low-cost welding and has good quality, thus the practicability and the durability of the golf club head can be improved to a large extent.
Description
Technical field
The present invention is a kind of batting panel and method for making thereof that is provided with the glof club head of double-layer powder metallurgy structure, is meant that a kind of square stance of keeping should have intensity and bounce, the glof club head that vibration-absorbing function is arranged again and can increase the service life.
Background technology
Golf is in fashion the whole world, and become at present a kind of universal motion gradually, because golf is in vogue, so be not only professional golfer, even the amateurish player who generally golf is considered as stress-relieving activity is also more and more high for the requirement of golf apparatus, and especially function and the texture for golf clubs then has higher expectation.
Therefore club head manufacturer researchs and develops at user's demand invariably, the batting panel of spheroid collision particularly, certainly also become the object of manufacturer's research and development, general batting panel is because direct and ball collision, therefore need to bear active force and the bounce that produces between batting moment and the ball, allow the striker grasp the direction and the distance of ball flight easily, yet, general batting panel normally comprises that by a sheet metal sheet alloy is made, when hitting panel collides spheroid, the vibrations that produced can be delivered to striker's hand, and allow the striker not feel well, in view of this, many dealers are in the hope of reaching the above-mentioned shortcoming of improvement, constantly research and develop and design, as Taiwan patent announcement No. 550106 " joint method of golf driver head " and Taiwan patent announcement M315595 number " joint construction of golf driver head ", the main purpose of this two patents case is to utilize two kinds of different materials to be combined into a batting panel, for example: stainless steel alloy sheet material, titanium alloy plate, to reach its default effect, yet first sheet material of its two kinds of different materials mainly is via the explosive welding mode it to be engaged to form a batting panel with second sheet material, and then batting panel is welded in vacuum welding case and glof club head body in the hard solder mode fixedly finish the club head finished product; Aforesaid hard solder engages fixed form, except that engaging cost height, production difference, when the batting panel of glof club head is long-time when colliding with spheroid, because of making this batting panel, the effect that is subjected to stress produces distortion, and then these two kinds of different sheet materials are become flexible easily from engaging to separate because of distortion, make therefore shorten the service life of glof club head, so necessity of further improvement is arranged.
Summary of the invention
The inventor is because aforementioned glof club head engages the cost height with different two sheet materials of batting panel, production is poor, and easily is out of shape, thereby causes the shortcoming that this joint separation is become flexible because of colliding with spheroid.Therefore, main purpose of the present invention is welded in batting panel on the bulb body with low cost providing a kind of, for example: argon welding, electron ion welding PLASMA etc., can finish and a kind ofly can keep intensity and the bounce that square stance should be arranged, and can increase again vibration-absorbing function and not can because of with spheroid collision cause separate loosening, and then the batting panel of glof club head that prolongs the service life of glof club head.
Based on above-mentioned purpose, major technique means of the present invention provide a kind of batting panel method for making that is provided with the glof club head of double-layer powder metallurgy structure, and its step comprises:
A. the strong alloying metal powder of rigidity is mixed plastic pellet respectively with the more weak alloying metal powder of rigidity and heat, evenly mix two kinds of ejaculation materials finishing granulation through kneader;
B. simultaneously with these two kinds different ejaculation materials with double molds and twin-screw ejection formation special machine, finish the double-layer alloy of a hard alloy layer and soft alloy-layer and give birth to confidential paper;
C. the double-layer alloy of hard alloy layer and soft alloy-layer is given birth to confidential paper,, mold the batting panel of pair of lamina structure via 1100 ℃ to 1400 ℃ high temperature sinterings and the program of coming unstuck;
D. with batting panel and glof club head body engagement and carry out the operation of next step processing.
In addition, the present invention provides a kind of batting panel that is provided with the glof club head of double-layer powder metallurgy structure again, and it is formed the formed double-deck batting panel of soft alloy-layer by strong hard alloy layer that alloy powder forms of rigidity and the more weak alloying metal powder of a rigidity.
Implement after the above-mentioned technological means, the accessible concrete effect of the present invention is:
1. when batting panel and bulb body engagement, can low-cost, the good welding manner solid welding of production.
2. when this batting panel and spheroid collision, hard alloy layer can provide due intensity of this batting panel square stance and bounce, increase the distance of spheroid flight, and soft alloy-layer, can absorb the vibration energy that square stance produces, and can reduce striker's sense of discomfort, the practicality that promotes the square stance that swings with and durability.
3. long-time during with the spheroid collision when this batting panel, this hard alloy layer and soft alloy-layer just are combined into one through the burning program of separating when making moulding, so can not separate looseningly, can prolong service life of glof club head.
