| A method for forming a convex tilting zone (23) at a main body surface (11) of a transverse element for application in a push belt for a continuously variable transmission comprises the steps of providing a die (30) having a stepped surface and placing the die (30) against the main body surface (11) under pressure. However, the die (30) is pressed against the main body surface (11) just outside of an area where the tilting zone (23) needs to be formed. By applying the die (30), a recessed area (27) is arranged in the main body surface (11), wherein retraction of the material of the transverse element takes place along an upper edge (28) of this area (27). A retraction area which is obtained in this manner adjacent to the edge (28) as mentioned is suitable to function as tilting zone (23). | ||||||

| Dans un procédé de fabrication d'un patin de chenille métallique (1) consistant à assembler ce patin sur une chaîne à chenille, on utilise un outillage à mouler ou à forger, servant à la mise en forme d'une pièce de base (10) et d'une semelle (20) du patin, une semelle (20) déterminée étant associée à une pièce de base (10) comprenant une pluralité de semelles (20). L'outil utilisé comprend au moins un élément façonnant la pièce de base (10) du patin et un élément façonnant la semelle (20) de ce patin. Le patin de chenille (1) ainsi mis en forme présente des oeillets de réception (2) sur l'une des faces du patin et un nombre égal de brèches (3) destinées à recevoir les oeillets, sur l'autre face du patin, ainsi que des guides latéraux (7) sur la partie inférieure du patin, et au moins un intervalle d'engrènement (6). | ||||||

A process comprising heating in an induction continuous oven a billet length whose weight corresponds to that of a finished segment including usual flash, to shape with a rough shape die said heated billet length, forging said partially shaped metal providing a shape close to final shape and size, trimming with an upside-down extension said shaped part, coining at square angles segment surface at sizes corresponding to those obtainable with cold tool machine working, drilling the segment flange with bolt holes, heating such segment to a temperature suitable for heat treating and finally cooling to complete such heat treatment. Die extruding and coining means are provided wherein the sproket segment (5) is extruded in upside-down condition and coined in a die (8) in flat condition wherein one (A') of its cavity walls is provided with a side loose piece (82) slidable on guides (181, 182) by engagement with at least one (280) of die halves (80, 81). |

| 96 | Procédé de forgeage pour la fabrication de maillons de chaînes de roulement, notamment pour engins de chantier | EP82401359.3 | 1982-07-21 | EP0071522A1 | 1983-02-09 | Balitch, Paul |
La présente invention concerne un procédé de forgeage pour la fabrication de maillons de chaînes de roulement, notamment pour engins de chantier, dans le respect des tolérances qu'exigent les dimensions et l'état de surface des faces d'appui et des sièges d'écrou des maillons finis sans qu'il y ait besoin d'usiner ces faces d'appui et sièges d'écrou. Ce procédé consiste essentiellement à chauffer dans un four électrique un lopin de métal d'une masse sensiblement égale à celle du maillon fini; à la préformer; à estamper à plat la pièce préformée aux dimensions nominales, à chaud du maillon à obtenir; à réaliser un calibrage horizontal de la pièce estampée combiné à un arasage de précision des faces d'appui et des sièges d'écrou; à calibrer en hauteur le maillon ainsi obtenu et traiter thermiquement celui-ci. On obtient en sortie de ce procédé, qui ne comporte pas d'opérations d'usinage, un maillon (1) dont les faces d'appui (10, 11) et les sièges d'écrou (32, 33) ont une précision dimensionnelle et géométrique entrant dans les limites des tolérances requises. |

| The present invention relates to an apparatus for machining a caterpillar chain link, and more particularly to an apparatus for machining a caterpillar chain link, in which a chain link is fixed by a jig, and the jig is provided at a front surface thereof with a front tool mounting plate coupled with two tools and provided at a lateral side thereof with a lateral tool mounting plate coupled with one drill, so that a pin hole and a bush hole are simultaneously machined in the chain link in such a manner that the pin hole is spaced apart from the bush hole by a constant interval, so that the machining time can be reduced. Both of a pin hole machining tool and a bush hole marching tool are provided in the front tool mounting plate, so that the pin hole is always spaced apart from the bush hole by a predetermined interval. A cutting oil passage is formed in the tool so that cutting oil can be discharged through the cutting oil passage, so that the cutting oil is directly sprayed on a cutting surface to be actually machined, thereby smoothly discharging chips. The surface roughness of the cutting surface can be prevented from being degraded due to a built-up edge, and the lifespan of the tool can be improved. | ||||||

| PURPOSE: A manufacturing method of a bush for a track link is provided to improve productivity of a product by reducing processing time, and to reduce manufacturing cost by preventing scraps. CONSTITUTION: A manufacturing method of a bush for a track link includes the following steps of: cutting a material used for the track link(10); heating the cut material by a cutting process(20); forming a hollow part of a cylindrical shape while pressing either side of the material(30); processing a diameter of the material(50); performing a heat process of the material; and polishing the diameter after heat treatment(70). The pressing process is a process for molding a material to the cylindrical shape. A partition wall is opened by the pressing process. | ||||||
