摘要:
A method of manufacturing a forged iron type golf club head with a cavity. The method of manufacturing comprises forming a billet into an intermediate club head body with a strike face comprising an upper region and a lower region; hot pressing a cavity into the rear portion of the intermediate body; and bending the strike face of the intermediate club head body to form a golf club head with a cavity and a planar strike face. Other embodiments are disclosed.
摘要:
A golf club head has an inner cavity and comprises a face member and a head main body which a front opening, which are connected to each other. The head main body comprises a sole portion, and a weight member which has a specific gravity greater than that of the head main body is fixed to an inner surface of the sole portion. A weld which fix the weight member to the sole portion is disposed at the peripheral edge of the weight member. The weight member has the width in the toe-heel direction of the head, which is smaller on its rear side than its front side.

A co-forged iron type golf club is disclosed. More specifically, the present invention discloses a co-forged iron type golf club with the body portion made out of a first material and at least one weight adjustment portion monolithically encased within the body portion of the co-forged iron type golf club head without the need for secondary attachment or machining operations. The present invention creates of an iron type golf club head from a pre-form billet that already contains two or more materials before the actual forging process resulting in a multi-material golf club head that doesn't require any post manufacturing operations such as machining, welding, swaging, gluing, and the like.

A method for manufacturing a golf club head includes providing a club head body produced by electric smelting an alloy base material including 0.04-0.07 wt % of carbon, 0.5-1.0 wt % of manganese, 0.5-1.0 wt % of silicon, less than 0.04 wt % of phosphorus, less than 0.03 wt % of sulfur, 15-17.7 wt % of chromium, 3.6-5.1 wt % of nickel, 2.8-3.5 wt % of copper, with the rest being iron and inevitable impurities. A solid solution treatment is proceeded at 1020-1080° C. for 80-100 minutes to form austenite and martensite in the club head body. A deep cooling treatment is proceeded between −120° C. and −80° C. for 7-9 hours to turn the austenite in the club head body into martensite. An aging treatment is proceeded on the club head body at 460-500° C. for 210-270 minutes to provide a hardness of HRC 36-46. A hosel is heated with high frequency waves at 900-1000° C. to posses a hardness lower than HRC 20.
摘要:
A method of forming a weight part integratedly connected with a forged golf club head includes steps of a club head forming step, at least one engaging recess forming step, at least one weight part engaging step, and a step of integratedly connecting the at least one weight part with the club head by forging. A crude rod is provided into a raw forging die and formed to a club head by a forging process. At least one engaging recess is formed in a sole portion or a back portion of the club head by a machining method. At least one weight part is engaged into the at least one engaging recess of the club head. The club head with the at least one weight part is pressed by a forging process to make the material of the club head cover the at least one weight part completely without gaps.
摘要:
A method of thermomagnetically processing a material includes disposing a workpiece within a bore of a magnet; exposing the workpiece to a magnetic field of at least about 1 Tesla generated by the magnet; and, while exposing the workpiece to the magnetic field, applying heat energy to the workpiece at a plurality of frequencies to achieve spatially-controlled heating of the workpiece. An apparatus for thermomagnetically processing a material comprises: a high field strength magnet having a bore extending therethrough for insertion of a workpiece therein; and an energy source disposed adjacent to an entrance to the bore. The energy source is an emitter of variable frequency heat energy, and the bore comprises a waveguide for propagation of the variable frequency heat energy from the energy source to the workpiece.
摘要:
A manufacturing method of an integrally forged golf club head has acts of forging a crude rod to form a blank of a main body of a golf club head, mounting a weight in a mounting recess of the blank of the main body of the golf club head, covering the mounting recess with an outer cover, and then welding and forging the blank of the main body of the golf club head and the outer cover to form a golf club head. Thus, the at least one weight is securely held in the golf club head and does not come off the golf club head, and also no noise occurs when the golf club head strikes a golf ball. Furthermore, the at least one weight is not exposed so that the golf club head has a good appearance and improved quality.
