Abstract

The present invention relates to a method of machining a master link disposed at a distal end of a chain and constituting a part of a track chain link of a lower driving device used in an endless track vehicle (a bulldozer, an excavator). According to the present invention, it is possible to rapidly perform the machining work by secondarily adjusting the horizontal degree and the vertical degree of the integrally manufactured front and rear master link in a short time after primarily wire cutting it by using an exclusive clamping jig for the primary wire cut and an exclusive clamping jig for the secondary machining center, and machine the interference portion generated at the time of the assembly of the master link with the corresponding product, by using the machining center provided with the ball end mill, the flat end mill, and the chamfer end mill, in a short time, thereby achieving reduction of the machining time, maintaining the uniform quality and reduction of the production expense.

Abstract

Disclosed therein are an apparatus and method for manufacturing a sprocket segment, which can manufacture the sprocket segment through a simplified process including hot precision forging, through hardening and painting, thereby reducing manufacturing period and cost and securing competitive power. The sprocket segment manufacturing method includes: a primary hot forging process of putting a heated billet in a booster die (10) mounted on a forging press to perform a distribution of volume; a secondary hot forging process of putting the hot forged material (M) in a blocker die (11) to form a rib face (4); a tertiary hot forging process of putting the secondarily hot forged material (M) in a finisher die (12) to keep right angles and planes of a toothed face (6) and the rib face (4); and a process of putting the tertiarily hot forged material (M) in a product guide die (22) of a trimming-piercing-coining die (13) to eliminate a flash and form bolt holes (7) simultaneously.
