Description

Forging process of golf head with complex shape

Technical Field

The invention relates to the field of manufacturing methods of golf heads, in particular to a forging process of a golf head with a complex shape.

Background

In the golf sports, the design of the golf tool has the diameter influence on the stability and the effect of hitting the golf ball, and further the hitting performance is influenced. The golf tool generally comprises a head and a club, the main point of force is on the head when hitting the golf tool, and the design of the head has been the most important ring for achieving good hitting effect.

A golf club head generally comprises a head body, a striking surface, and a weight. The middle part of the golf head body of the existing golf head is designed into a hollow structure so as to reduce the weight of the shell of the existing golf head, and the reduced weight is installed at a proper position on the golf head body in a counterweight mode, so that the gravity center position of the existing golf head is changed, and a good batting effect is achieved. In order to change the position of the center of gravity, in the manufacture of the head body, a weight-reducing groove and a mounting groove need to be arranged at the lower part of the head body, and the number of weights, mounting positions, selection sizes and the like of different golf heads are different, so that the shape of the head body is extremely complicated. In the prior art, the ball head body is usually manufactured by a casting method. But on one hand, the striking effect of the cast ball head is not good; on the other hand, casting pinholes are formed on the casting surface, and the pinholes cannot be treated in a nickel-chromium electroplating and vacuum coating mode and cannot meet the surface quality requirement of the golf head.

Therefore, the golf head is manufactured by a forging process, and the material performance is changed by forging, so that the hitting effect is better. However, the shape of the golf club head body is complicated, and the grooves on the club head body cannot be directly formed by forging, which brings certain difficulty to the manufacture of the forged golf club head.

Detailed Description

The technical solutions of the present invention are further described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following.

The forging process of golf head with complicated shape includes one head body, one hitting surface and one weight.

In order to achieve a good hitting effect, the gravity center position of the golf head is often customized by a user according to the hitting habit of the user. When designing golf club head, the middle part design of bulb body is hollow structure in order to alleviate the weight of its casing, and will be installed the suitable position on the bulb body by the mode of counter weight by the weight of lightening to change its focus position and satisfy user's demand.

Fig. 1 shows a golf club head body structure designed according to the user's needs, in order to change the center of gravity of the golf club head, a groove 3 is processed on the lower part 1 of the golf club head body to reduce the weight of the middle upper part of the golf club head body. In the prior art, the golf head with a complex shape is usually manufactured by casting the head body. But on one hand, the striking effect of the cast ball head is not good; on the other hand, casting pinholes can be formed on the casting surface, the surface of the golf head cannot be treated in a nickel-chromium electroplating and vacuum coating mode, and the surface quality requirement of the golf head cannot be met.

The forging process of the golf head with the complex shape can finish the manufacture of the golf head body in a forging form, and the forging process sequentially comprises the following steps: s1, blanking; s2, rough forging; s3, cutting; s4, embedding the die; s5, precision forging; and S6, modulus taking.

Step S1 is to cut out a ball blank according to the design size of the ball body.

Step S2 is to roughly forge the golf club head blank, and as can be seen from fig. 1, the designed golf club head has a convex portion on the upper portion 2 of the golf club head body, and if the groove 3 is to be cut, the convex portion will block the cutting path a, so that the golf club head cannot be machined. Therefore, as shown in fig. 2, it is required that the upper portion 2 of the ball head body be inclined at the time of finish of rough forging at an angle of inclination that ensures that the upper portion 2 of the ball head body does not obstruct the machine tool feed path a for cutting in step S3. Since the forging process cannot directly forge complex shapes such as the groove 3, the groove 3 is machined by a cutting machining method. In specific implementation, the inclination angle of the upper portion 2 of the ball head is preferably just enough to not obstruct the machine tool feed path a of cutting processing when rough forging is completed, so as to avoid the situation that subsequent finish forging forming is difficult due to an excessively large inclination angle.

As shown in fig. 3, in step S3, the lower portion 1 of the ball head body is machined by a CNC machine to form the groove 3.

As shown in fig. 4, in step S4, a wedge 5 is inserted into the recess 3. The wedge 5 has the same size as the groove 3, and the wedge 5 is manufactured to the designed size of the groove 3 before step S4.

As shown in fig. 5, in step S5, the golf head body fitted into the wedge 5 is finish forged, and the head body upper part 2 tilted in step S2 is restored and finish forged to a design size. Because the wedge 5 is embedded in the groove 3, the wedge 5 plays a supporting role for the groove 3 in the precision forging process, and the size of the groove 3 cannot be changed due to the precision forging.

Step S6 is to take out the wedge 5 in the groove 3.

All the design sizes are provided by a user or the sizes determined by simulating and drawing the shape of the golf head body by using a computer 3D molding technology according to the shape, the mass and the gravity center of the golf head and the material density of the adopted blank. In the implementation, the number of the grooves is one or more, and the design size of the grooves is designed according to the needs of users. And step S2, after rough forging, the requirement of the upper part of the ball head body on the inclined angle to avoid all the feed paths during groove cutting is met.

The golf head body with the complex shape can be manufactured by using the forging process, so that the material property is changed, and the manufactured golf head has better quality and better hitting effect. The invention directly ensures the surface smoothness and the finish degree through the precision forging molding, meets the requirements of users on high-quality ball heads, has less process steps and low technical requirements of workers, and has higher yield compared with the traditional ball head casting technology.
