Manufacturing method of upper cap and lower cap of golf club head

Abstract

The invention relates to a manufacture method of an upper cap and a lower cap of a golf club head, which comprises the following steps: (a) according to the widths and the surface curvatures of the upper cap and the lower cap of a preprocessed club head, computing an area which can be used for arranging at least two unit caps in interlaced / non-interlaced directions, and reserving a section of oddment the stretching forces of which can be counter balanced when the two unit caps are molded at the adjacent segment where the two unit caps are molded, wherein the the total width of the oddment andthe required thickness are made of metal / nonmetal matrix composite materials; (b) molding the two unit caps arranged in the interlaced / non-interlaced positions into a whole in the molding process, wherein the stretching forces generated when the two unit caps are molded form mutual drawing through the oddment arranged in the adjacent position; and (c) cutting the oddment after the two unit caps are molded. The invention can obtain a preferred end of part, enables the molded two unit caps to have small deformation probability in processing and a level precut surface, and can obtain the upper cap and the lower cap of the club head having precise sizes and close contact surfaces.

Description

technical field [0001] The invention relates to a manufacturing method of the upper and lower covers of the golf club head, mainly in that the upper and lower covers of the club head can be processed at one time so that the two prefabricated covers can be in a staggered / non-staggered orientation It is set so that the two covers form a mutual traction on the extension force generated during the forming through a section of the remaining material during the forming process, so that the formed two covers can obtain a close contact surface after being cut by the remaining material. The upper and lower covers of the club head. Background technique [0002] At present, when the industry processes the club heads of wooden clubs for hitting long-distance balls, in order to increase the speed of hitting the ball and increase the driving distance when hitting the ball, metal-based composite materials will be used to die-cast the required club heads. The upper and lower covers are gro...

AI Technical Summary

Problems solved by technology

Therefore, the industry changed to a punching method to process the metal-based composite material one at a time into the upper and lower covers of the required club head. The azimuth is extended so that boundary deformation occurs / or part of the peripheral deformation occurs during the removal process, resulting in the inconsistency of the peripheral contact surfaces of the upper and lower covers when they are close together, becoming an unqualified eliminated product, and due to composite The material is a high-priced material. If the elimination rate in the manufacturing process is too high, the processing cost will be relatively increased.
