| Disclosed herein is a method of manufacturing a master link which connects ends of track chains of an endless track to each other. More particularly, the present invention relates to a method of manufacturing a master link which includes a pair of partial link units that are separably coupled to each other, and which can markedly enhance the degree of precision in machining the partial link units and the quality of the product. The method includes forming a wire-cutting reference hole at a predetermined position in the master link so that a wire is inserted into the wire-cutting reference hole, and forming the first and second partial link units by wire-cutting after inserting the wire into the wire-cutting reference hole. | ||||||

| Disclosed is a method for manufacturing an element for a CVT belt, comprising a body portion (22L, 22R) having right and left sides and a tapered portion with a downwardly reducing width, a neck portion extending upward from the body portion, and a head portion extending upward from the neck portion. The manufacturing method comprises a first punching step in which a metal strip blank (31) which has a uniform thickness and a width which makes it possible obtain elements arrayed on an even number of lines in an arrangement in which the head portions are opposed to each other or an arrangement in which the body portions are opposed to each other, is punched along an outline ((33L, 33R) of an excess material (21b) added to profiles of the left and right sides (21L, 21R) of the body portions, and along an outline (58L, 58R) of an excess material (32b) added to a profile of a lower side (32L, 32R) of the body portion; a plastic deformation step in which the blank is compressed in the thickness direction to form a predetermined projection and depression, and form the tapered portion while displacing the material in the outline directions; and a second punching step in which the element is obtained as a product by punching the blank. | ||||||

| There are proposed a track link production method capable of providing markedly improved wear life with good cost performance and a track link produced by this method. To this end, the track link production method includes a heat treatment process (Steps 4, 5) of applying quenching and low temperature tempering treatment to a whole link material after hot forging (Step 2), and is designed such that desired machining is applied to the link material (Step 3) before the heat treatment process (Steps 4, 5) and such that after the heat treatment process (Steps 4, 5), tempering (Step 6) and finish machining (Step 7) are sequentially applied to some of the parts which have undergone the machining process, the some parts including at least parts where high dimensional accuracy is required. | ||||||

| A billet (10) is pressed with a first blocking punch (36, 38). Thereafter, the billet is rotated approximately 90.degree.. A second punch (50) is pressed against the billet while a split ring die assembly (58) substantially surrounds the billet and constrains outward flow of the steel. The split ring die assembly includes projecting regions (64, 66) matingly received in recesses (14, 16) created by the first blocking punch. A finishing punch (90, 92) is pressed through the billet to complete formation of openings (94, 96). Preferably, a trimmer (100) removes any flashing from the finished billet. | ||||||

| 80 | Track chain link and forging process for the manufacture of track chain links | US398176 | 1982-07-14 | US4449357A | 1984-05-22 | Paul Balitch |
| The invention described herein concerns a forging process for the manufacture of track chain links, especially for worksite machines and vehicles; this process produces links that conform to the tolerances required by the dimensions and the surface quality of opposed attachment mounting and link contact surfaces and nut seats of finished links without it being necessary to machine these surfaces or nut seats. This process includes heating a metal billet in an electric furnace, the billet having a mass that is approximately equal to that of a finished link, preforming the billet, then flat stamping the heated billet. A combined shaping and levelling step carried out on the stamped piece forms parallel opposed sides and nut seats in predetermined spaced relationship to each other. The resulting link is controllably sized and then subjected to a heat treatment. At the end of this process, which requires no machining, a link is obtained (1) whose opposed surfaces (10,11) and nut seats (32,33) have geometric and dimensional relationships that are conform to the limits of the required tolerances. | ||||||
