Abstract

This invention is related to a method for joining a modular plate to a golf club head, comprising the steps of: affixing a body to a positioning jig; machining joints of the body and the modular plate at where they will be joined such that the dimensions at the joints are precisely controlled; placing and securing the modular plate to where the plate is joined to the body; confirming and setting the advancing track of a laser beam during the first welding process; laser welding the joints between the body and the plate. Laser welding uses an oscillator to emit a laser beam of a small conical angle, such that dense points with high energy may be formed by the optical system so as to allow for welding. As such, the regions affected by the thermal energy is restricted while featuring such the advantages as, high infiltration, low thermal deformation, narrow welding paths, high precision, efficient welding, and high productivity, at the same time.

Description

The present invention relates to a method for joining blocks of a golf club head. 'Under = A method of joining the blocks of a golf club head using a thunder connection technique', so as to achieve a narrow heat-affected zone, good permeability, and thermal deformation. Practical methods such as small volume, high bead L, high speed, high speed, and high yield are currently used in the golf club manufacturing industry to weld golf club heads: D 2 has the following joining methods. —Set and hitting panel) The wood head is composed of ㈣ming, please cooperate with 1 · vacuum brazing method · and then refer to the seventh figure, the hitting panel, (4 3) the periphery and the body (4 Q) Between the mounting groove seat (4 丄) 2: a gap of a large size 'and the powder-shaped metal welding material (4 2) is filled in the mounting groove seat (41) and the ball striking panel (the welding material The melting point of (42) must be lower than the pry point of the main body (4k material panel (43)), and then the whole is placed in ::: or a high temperature furnace protected by an inert gas, and heated to the material (42) When the ”charm” is above, the welding material (42) is filled with 1 capillary action in the mounting slot (41) and The panel body (two of the: side, in order to weld the hitting panel (43) to high temperature :::: empty: welding method: the entire wood head must be placed in a vacuum furnace or body #combining its body with the hitting panel In the world, the role and influence of the shaping of the wooden club head will cause the wooden club head to be heated and changed ", so its heat-affected zone is large and there is a change due to overheating.

Description of the invention (>) In the U small gap between M7 and rr Welding is solid, so 押: the permeability of the material will be affected by temperature and welding == element, still "Nagoko, Minato ^ 面面 状况 # Multiple reasons, said that the permeability may not be as expected and the body After all, it ’s tempting, clever, ..., Lianshe, and “there ’s a backlash through the intermediate medium (welding material). The degree of combination is not as good as the direct consolidation of the body and the hitting panel. Dao Fei! 1 ° welding method: Due to the welding 1 formed by the τ1g welding method, it must be smoothed and ground afterwards to make it expensive, poor in precision, and the production speed is equivalent to that of a wooden pole. When the material of the head is a titanium alloy, the bead color of the TIG welding method will be significantly different from the metal color of the # head itself, and a very obvious welding mark will be left, and it must be covered by a surface coating method. Very troublesome. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 3 · —General welding method: The general welding method is mostly used in the combination of the stainless steel body and the heterogeneous metal hitting panel. The combination method is to install the hitting panel on the body of the wooden talent head. The slot seat is then welded with welding material along the adjacent seams on the surface. Because this welding method will have small gaps and the bonding strength is not tight enough, it is easy to crack here when hitting the ball. In view of this, the inventor has devised a method for joining the blocks of the golf club head according to the present invention, so as to provide a method of joining the blocks of the golf club head by using laser fusion technology, so as to achieve a narrow heat-affected zone and penetration Good performance, small amount of thermal deformation, small bead, high precision, fast speed and high output.

Many practical methods of efficacy. The main purpose of the design of the present invention is to provide a golf club cymbal block joint with many functions such as narrow heat-affected zone, good permeability, small thermal deformation, small bead, high precision, high speed and high yield. Method: the main body is fixed on a positioning mold, and the joint between the main body and the block is processed by a processing machine so as to reach the precise size of the joint, and then the block is placed and fixed at the joint of the main body and the mosquito. During the second welding, the travel track of the laser beam is confirmed and set, and then the laser welding method is used to weld the joint of the body and the block; because the laser welding method uses a vibrator to emit a laser beam with a small expansion angle After optically forming small dots with high energy density for welding, it can be used to achieve the design goals of narrow heat affected zone, good permeability, small thermal deformation, small bead, high precision, high speed and high output.

The joint between the body (1 〇) and έ and; t # r Ί / 1, Μ ^, Zhao shot melting Mα (11) Risi, can == Γ and make the body (1 "and the block (") Welding is the mother's mother's daughter. The method of welding does not require the material to be welded, so that the two ends, the body, and the block can be melted and joined, which can avoid the amount of solder penetration. It is not necessary to consider the remaining reserve of the welding amount. The second is to consider its design conditions and increase the number of heads that can be made. In addition, the laser welding method does not require a vacuum chamber. Welding can be performed at room temperature. machining. In addition, when the laser is melted, the gap between the bodies (1 (...) between the joints (11) to be fused is extremely small, and the gap between the beam bodies (1 0) and the Xiao blocks (14) is smaller than The thickness of the workpiece is 1 / 1G, but the smaller the gap is, the deeper the penetration depth of the dissolution channel is, the flatter the dissolution channel is. By designing the above method, the blocks of the golf club head of the present invention are joined. The method has the following advantages: 1. The amount of thermal deformation is small ... Since the laser welding method can be performed without contact at normal temperature, and does not require a vacuum chamber or a high temperature furnace, the entire club head will not be deformed due to the influence of heat. 2 · Heat ~ Sound zone is fast, high speed and high output ·· Because the laser welding method is to use a vibrator to emit a laser beam with a small expansion angle, and then form a small spot with high energy density through the optical system for welding, so The heating range is extremely narrow, the crystal grains will not be coarsened, and the welding speed is fast, which can obtain a high yield. ° 3 · Good permeability, small bead and high precision: due to the laser welding method A7 B7 Invention description (do not need too much time You can & ★ the deeper the penetration depth, cleanliness; a, the smaller the person ^ ^ the more flat, and before the life shot welding method, will ram M, A she ... Milling and confirming the trajectory at the same time, so the welded product has high precision and extremely low defect rate. The square path is only 4: the volume is increased. The maximum volume that can be made by the club head can be increased. The method of joining the blocks of the head is that jl has the advantages as described above.
