Method for producing a vehicular endless track link

摘要

The present invention relates to a method for producing a link of a vehicular endless track. According to this method, low-carbon boron steel is selected as a starting material for producing the link. The present invention involves the steps of forging and hot-trimming the link material to form a substantially final link shape. Then, the link material is rapidly cooled so that a metallic crystal structure of the link material is converted to martensite. Next, the link material is tempered at a low temperature. Finally, a pin hole and a bushing hole are machine finished in the link material.
