Ball chain connecting ring manufacturing method and ball chain connecting ring manufactured thereby

摘要

The present invention relates to a method for manufacturing a ball chain linkage, and more particularly, in manufacturing a linkage that can be manufactured as a ball chain by inserting balls and continuously connecting them, the work manpower is minimized by cutting and manufacturing by a mold Thus, a large number of connecting rings can be manufactured continuously in a short time, and during the mold processing process, the connecting grooves that can connect the rings are cut and then separated from the material and discharged. It relates to a method for manufacturing a ball chain linkage capable of maintaining a solid connection state by closing a groove by soldering or welding, and a ball chain linkage manufactured thereby. To this end, the method for manufacturing a ball chain linkage according to an embodiment of the present invention includes a primary rolling step of flatly pressing a material, a forging step of reinforcing strength by striking the rolled material, and a material irregularly deformed by forging The second rolling step of flattening the surface by pressing the surface, the inner cutting step of cutting the inner space made of the connecting ring from the rolled material, the inner side cutting the outer side of the cut material as a whole while cutting to form a connection portion for a certain section An outer cutting step of cutting the cut material not to be separated, a cutting groove cutting step of cutting one side of the connecting ring 100 to form a cutting groove 150 that can connect the connecting ring 100 to each other (S60) , a separation and discharge step (S70) of separating and discharging the connection ring 100 from the cut material, and a finishing step (S80) of polishing and washing the discharged ring to finish.
