摘要： A rotary forming machine assembly including a lower base (12) and a pair of spindle housings (14) including front (16) and rear (18) walls. A tool spindle (20) is rotatably mounted between the front (16) and rear (18) walls of each of the housings (14) for rotation about spaced axes (B). A deflection control bar (26) extends between and interconnects the front walls (16) of the spindle housings (14). The control bar (26) limits the distance apart the (B) axes of the tool spindles (20) may move at the front walls (16) in response to the forming of a workpiece (22) between the tool spindles. The control bar is adjustably supported on the front walls (16) for selective movement in a direction parallel to a plane intersecting the axes (B). A dual thickness adjuster member (118) includes a rectangular thickness (148) slidably disposed within a rectangular groove (114) formed in the front walls (16) and a trapezoidal thickness (154) slidably disposed within a recess (112) formed in the control bar. An adjustment screw (138) threadedly engages an aperture (142) in the top (144) of the adjuster member (118) to raise and lower the adjuster member (118), which places the control bar in tension to prevent the axes (B) from moving apart in response to a forming or gear-splining operation being performed on the machine.

摘要： Une machine de formage par rotation comprend un bâti inférieur (12) et une paire de cages (14) de mandrin comprenant des parois frontales (16) et arrière (18). Un mandrin porte-outil (20) est monté en rotation entre les parois frontales (16) et arrière (18) de chacune des cages (14) pour tourner suivant des axes espacés (B). Une barre de commande de déflexion (26) s'étend entre les parois frontales (16) des cages (14) des mandrins et relie entre elles ces parois frontales. La barre (26) limite la distance de déplacement des axes (B) des mandrins porte-outil (20) au niveau des parois frontales (16) en réponse à la formation d'une pièce à usiner (22) entre les mandrins porte-outil. La barre (26) est supportée de manière réglable sur les parois frontales (16) pour effectuer un mouvement sélectif dans une direction parallèle au plan intersectant les axes (B). Un organe d'ajustement (118) à double épaisseur comprend une épaisseur rectangulaire (148) disposée de manière coulissante dans une rainure rectangulaire (114) formée dans les parois frontales (16) et une épaisseur trapézoïdale (154) disposée de manière coulissante dans un évidement (112) aménagé dans la barre de commande. Une vis de réglage (138) est vissée dans un orifice (142) dans la partie supérieure (144) de l'organe d'ajustement (118) pour faire monter et descendre l'organe d'ajustement (118), mettant ainsi la barre de commande en tension pour empêcher les axes (B) de s'écarter suite à une opération de formage ou de taille d'engrenage effectuée sur la machine.

摘要： A method and apparatus (12) for cold sizing a round workpiece (14) having round surfaces of cylindrical shapes that are coaxial about a central axis A of the workpiece and have different diameters. A support (54, 55) rotatably mounts the workpiece (14) about its central axis A between a pair of die assemblies (24a, 24b) which are spaced from each other. Each die assembly (24a, 24b) includes a plurality of dies (56, 58, 60, 62) that are respectively aligned with the round surface (46, 48, 50, 52) of the workpiece (14). Movement of the die assemblies in opposite directions as each other engages sizing surfaces (66, 68, 70, 72) of the dies with the aligned round surfaces of the workpiece to pressure size the workpiece surfaces. In one embodiment of the sizing apparatus (12), the dies assemblies (24a, 24b) have elongated shapes and are moved rectilinearly in a parallel relationship to each other to perform the sizing. Another rotary embodiment of the sizing apparatus (12') includes rotary die assemblies (24a', 24b') mounted by associated spindles (85) whose rotation likewise pressure sizes the round workpiece surfaces. Both embodiments of the sizing apparatus are disclosed as including forming projections for forming projections for forming projections such as splines (82) and/or helical thread (84) on the sized surfaces of the workpiece.

摘要： A loader (10) for a forming machine (12) is disclosed as including a horizontally elongated transfer beam (46) supported by a linkage (52) and moved by a dual output cam unit (62). A first output (64) of the cam unit (62) is connected to an intermediate portion (50) of the beam (46) and a second output (66) thereof is connected to the linkage (52) to cooperatively move the beam (46) vertically and horizontally in a closed path such that workpieces (30) are moved into alignment with a work station (22) of the machine (12) for forming and out of alignment therewith after the forming is completed. The cam unit (62) has first and second cams (68, 72) that move associated first and second followers (200, 224) to move the first and second outputs (64, 66) which respectively actuate horizontal and vertical movement of the transfer beam (46). A slide connection (210) connects the first follower (200) with an intermediate portion (50) of the transfer beam (46), and an actuating link (92) connects the second follower (224) with one end lever (78) of the linkage (52) to actuate the vertical transfer beam movement. A connecting link (88) of the linkage (52) connects the one end lever (78) with another end lever (80) to provide coordinated support of the opposite ends (48) of the transfer beam through roller slide connections (86) that allow the transfer beam (46) to move horizontally under the impetus of the first output (64) of the cam unit (62).

摘要： A rotary forming tool (12) and spindle (14) therefor disclosed permit forming of larger diameter workpieces (26) than heretofore possible with multiple tools that are individually replaceable on each spindle. The rotary tool (12) has a tool body (78) of a generally C shape including an outwardly facing forming face (80) and leading and trailing end mounting surfaces (86,88) coplanar with each other as well as including an intermediate support surface (92) on the concave inner side of the tool. Locating surfaces (92, 94) respectively adjacent the end support surfaces cooperate therewith in mounting the tool. A tool holder (110) of the spindle (14) includes a pair of tool mounts (114) each of which includes a pair of flat end mounting surfaces (116, 118) coplanar with each other and an intermediate mounting surface (120) between the end mounting surfaces extending parallel thereto at an outwardly spaced radial position. Locating surfaces (122, 124) on a central hub (132) of the tool spindle (14) adjacent flanges (126,128) thereof which define the end mounting surfaces cooperate therewith to accurately locate the mounted tools. A support wall (130) of each tool mount (114) engages a side wall (108) of the associated tool to provide axial positioning of the mounted tool.

摘要： A toothed rack (22) disclosed has a toothed forming face (24) of a novel construction for forming splines (42) in a thin-wall sleeve (36) of a power transmission member (28) by meshing of the rack and a toothed mandrel (26) with the sleeve therebetween to form the splines. The toothed forming face has leading, intermediate, and trailing tooth groups (40a, 40b, 40c) that perform the splining. The pitch line tooth thickness of the leading tooth group is at least equal to and preferably greater than the pitch line tooth thickness of the trailing tooth group which has an addendum of a greater height than the leading tooth group. The teeth of the intermediate tooth group have an addendum height that is shorter than the teeth of the trailing tooth group and preferably equal to the addendum height of the leading tooth group. The pitch line tooth thickness of the leading tooth group is equal to and preferably greater than the pitch line tooth thickness of the intermediate tooth group. The profile of the intermediate teeth from the tip to the root thereof is the same as the profile of the trailing teeth from the tip thereof toward the root thereof for the same distance. All of the teeth have faces defining the same pressure angle as each other.
