Manufacturing method of golf iron rod head

Abstract

The invention relates to a manufacturing method of a golf iron rod head. The manufacturing method mainly comprises the steps that a preformed steel substrate is sequentially subjected to a rough-stage hot forging procedure, a middle-stage hot forging procedure, a fine-stage cold forging procedure, a ball striking surface cold pressing forming procedure and a rod part drilling procedure, and an iron rod head is formed, wherein the shape forming of the iron rod head is carried out by a multistage progressive hot forging and cold forging combination technological means, the time from formation forging to cooling can be shortened, in addition, the shape and size of the formed iron rod head are stable, in addition, the grinding processing quantity of the rod head can be reduced, the weight of the final product of the completed iron rod head is precisely controlled, and further, the yield of the iron rod head is effectively improved.

Description

technical field [0001] The invention relates to a manufacturing method of a golf club head, especially a manufacturing method of a golf iron club head. Background technique [0002] At present, it is known that iron club heads made of metal materials are mainly manufactured by hot forging. The implementation steps are to cut the rod-shaped carbon steel base material into an appropriate size, and then send the carbon steel base material into an electric furnace and heat it to The carbon steel base material has a high temperature state of high plasticity (about 1200°C), and the carbon steel base material is forged into a predetermined rough billet by means of hot forging with a forging die, and then the rough billet is allowed to cool naturally, and the club head is cut Excess material around the rough base, and grinding of the rough base of the club head; followed by a second heating and hot forging step on the rough base of the club head, after hot forging, it is taken out a...

Problems solved by technology

[0005] The main purpose of the present invention is to provide a method for manufacturing iron golf club heads. It is hoped that through this invention, the problems of time-consuming and labor-intensive manufacturing process, low production capacity and difficult quality control of the existing complete hot forging method for manufacturing iron club heads can be improved.
