摘要： Embodiments herein provide formed wire tie strap for a saw chain. Embodiments also provide a saw chain including one or more formed wire tie straps. The formed wire tie strap may include a body with one or more integrated rivets extending from the body. In some embodiments, the body may be substantially flat. The rivet may include a rivet head configured to engage a rivet hole of an opposing tie strap and a shoulder configured to engage a rivet hole of a connecting link, such as a drive link. Some embodiments of the formed wire tie strap may include a pair of integrated rivets extending from the body. Some embodiments may include a rivet hole disposed in the body of the formed wire tie strap.

摘要： By press-fitting a cylindrical blank (D) into a die (1) with one of a pair of punches (2, 3), and at the same time press-fitting small diameter end portions (2a, 3a) and tapered portions (2c, 3c) of the pair of punches (2, 3) into both ends of the cylindrical blank (D) while restraining both end surfaces of the blank (D) with cylindrical members (4, 5) movable on the outsides of the punches (2, 3), the external circumferential surface of the blank (D) is finish molded to the required diameter by the internal circumferential surface (1a) of the die (1) and, at the same time, tapered surfaces (E3, E4) are formed on the inner circumferential surface in both ends of the blank (D). The process produces a bushing (E) with its internal surfaces (E2, E3, E4) accurately coaxial, and with the external surface (E1) accurately formed to the required diameter.
