Abstract

The invention relates to a manufacturing method for golf club face element with different thickness distribution, comprising a plurality of steps: firstly, cut the chosen metal sheet into a metal plate of scheduled shape; secondly, press the metal plate after the first step with scheduled concavo-convex shape; thirdly, mill a single side of the concavo-convex metal plate after the second step into flat, making the metal plate with different thickness distribution. The method has the advantages of reducing production cost and equipment cost and excellent quality of the finished product.

Description

The method for making of the golf driver head batting face component of tool thickness different distributions

Technical field

The present invention relates to the method for making of golf driver head batting face component, be meant a kind of method for making of golf driver head batting face component of tool thickness different distributions especially.

Background technology

Known golf driver head batting face component (face) is with the metal bar forging molding, and its forging pressure needs more than 400, and material unaccounted-for (MUF) is about more than 50%.If the golf driver head batting face component will use β titanium forming materials; its crystal grain can change more than 800 ℃ because β titanium material temperature surpasses; cause intensity to reduce; therefore its processing temperature must be controlled at below 800 ℃; bar forging will be become thickness under low processing temperature only is about 1.5 to 4mm batting face component; be very difficult to forge, size Control is difficult for, processing difficulties.And, what known batting face component had cup-shaped (cup face), bar forging will be become thickness under low processing temperature only is about 1.5 to 4mm batting face component, especially difficulty.

Summary of the invention

At the problems referred to above, main purpose of the present invention is to provide a kind of method for making of golf driver head batting face component of tool thickness different distributions, and its processing procedure is comparatively simple and easy, and finished product is superior.

For achieving the above object, the method for making of the golf driver head batting face component of a kind of tool thickness different distributions provided by the present invention is characterized in that including the following step: step 1, the raw metal sheet material of selecting for use cut out the sheet metal plate of reservation shape; Step 2, the sheet metal plate of step 1 is extruded predetermined concaveconvex shape; Step 3, the concavo-convex metallic plate single face of step 2 is milled flat, make it form different thickness.

In the technical scheme of the invention described above, step 2 is that the central part of metallic plate that step 1 is cut out protrudes toward a side, and the central part outside forms position, a plane, and the outside, position, plane is protruded toward the another side and formed boss.

In the technical scheme of the invention described above, step 3 is to mill the concavo-convex metallic plate that step 2 is made flat to flushing with the depression plane of central part from described boss single face.

In the technical scheme of the invention described above, also including step 4, is that the metallic plate that step 3 makes is pressed into cup-shaped, to form the cup type batting face component of tool thickness different distributions.

Adopt technique scheme, the invention has the advantages that the use plate forming, its material unaccounted-for (MUF) is about 20～30%, can reduce cost.The forging machine that it need not use high pressure can reduce equipment cost.Employing is pressed into the concavo-convex processing that mills single face more earlier with flat board, is very easy to the distribution of control thickness, and the manufactured goods quality is superior.

The specific embodiment

Also the present invention is described in detail in conjunction with the accompanying drawings now to lift following examples.

As Fig. 1～shown in Figure 6, the method for making of the golf driver head batting face component of tool thickness different distributions of the present invention includes the following step:

Step 1, the raw metal sheet material of selecting for use (for example β titanium or maraging steel etc.) is cut out the sheet metal plate 10 of reservation shape (being the expansion shape of batting face component), as shown in Figure 1 and Figure 2.

Step 2, the sheet metal plate 10 that step 1 is cut out extrude predetermined concaveconvex shape, make it become concavo-convex metallic plate 20, as shown in Figure 3, Figure 4.Be to need the part of attenuation toward metallic plate 10 one side direction belling together.

Step 3, concavo-convex metallic plate 20 single faces that step 2 is made mill flat, form different thickness, as Fig. 5, shown in Figure 6.It is flat to be that belling face 21 single faces with concavo-convex metallic plate 20 mill, and forms the metallic plate 30 of tool different-thickness.

Be that the central part of label 23 another side 22 directions of metallic plate 20 in the figure are protruded in step 2, the position of label 24 almost still is the plane, and the outside 25 at label 24 positions is the position to side 21 projectioies.Side 21 is milled flat, as Fig. 5, shown in Figure 6, promptly mill to flushing with central part 23, central part 23 keeps the thickness of original sheet material, and the plane partly 24 mills partly thickness, and plane partly 24 exterior projection position 25 mills maximum thickness, forms the thinnest position.The thickest position 23 of central authorities forms the central part of striking surface, has maximum ga(u)ge.

The present invention is by simply cutting, punching press, milling steps such as flat, compression moulding, dull and stereotyped sheet material can be made golf club head batting surface with thickness different distributions, its step is simplified, and does not need expensive process equipment, and can construct at low temperatures, do not exist the anxiety of destroying timber intensity to consider, and finished size is accurate, and is superior in quality, and materials are economized again, escapable cost, the value on the dark tool industry.

Fig. 7, shown in Figure 8 for another example, it is the batting face component that is pressed into cup-shaped of second embodiment of the invention, second embodiment holds continuous first embodiment, three steps in front are identical, step 4 that how difference has been second embodiment, the metallic plate 30 of the tool different-thickness that step 3 is made is pressed into cup-shaped, promptly becomes the golf club head cup type batting face component 40 of tool thickness different distributions.Last again the ora terminalis of cup type batting face component 40 is milled partly, makes it become a protuberance 41, so as in follow-up manufacturing process with bar head capsule body assembling operation.As Fig. 7, shown in Figure 8, the thickest position 23 of central authorities forms the central part of striking surface, has maximum ga(u)ge, is bent to form cup-shaped from the thinnest position 25, and sheet metal thickness is still possessed at ora terminalis position 26, the convenient protuberance 41 that forms.
