摘要： A tire press in one form has mounted on the press head beam a precision loader for the uncured tires. The beam moves vertically and then laterally or horizontally while maintaining the top mold section in parallelism with the bottom mold section for concurrent opening, loading of the uncured tire and discharge of the cured tire from the press. The invention includes a pair of tire chucks (110, 111) mounted on a loader beam (76) for precise vertical movement through an electric motor driven rack and pinion drive. The loader beam may be in turn mounted on the press head beam but through a lost motion connection. In this manner the loader is uncoupled from the press head during the final loading horizontal travel thereof to allow independent movement of the loader and press head. The loader is biased toward the press head by springs (67). When the press opens the loader moves with the press head but is stopped short of the full open position of the press head and is engaged by external alignment blocks (50) which then move the loader relative to the press head against the spring pressure during the final portion of movement of the press head to locate the loader precisely independently of any inconsistent full «open» position of the press or press beam. The loader beam is guided in to final loading position independently of the press beam in both a lateral and fore and aft direction. The loader beam thus floats in a horizontal plane in both an X and Y direction. In tiltback presses the loader may be mounted on a carriage supported independently of the press head.

摘要： A tire press, loader and method employs a stationary bottom mold section (181) and a vertically movable top mold section (176) which moves upwardly to open the press clearing the area therebetween for discharge of the cured tire and loading of the green or uncured tire. The press loads the green tire initially into the top mold section centering and holding the top bead of the green tire on the bead ring of the top mold section. To position the uncured tire for such top loading there is provided a loader (35) which engages the uncured tire at the lower shoulder of the tread area. The loader includes pivotally movable chuck sector assemblies (113), each mounted on a ring (98). The ring can readily be centered with respect to the axis of the mold sections and each assembly can be moved concurrently uniformly radially of the ring to accommodate tires of different sizes. The loader elevates the uncured tire from in front of the press and then positions it within the open press at the proper elevation with respect to the top mold section after the cured tire has cleared the press. The top mold section includes a mechanical chuck the segments (163) of which then extend to flower from cylindrical form to a conical form of increasing apex angle and then to a horizontal plate form in which they are locked. During opening of the press the bladder (161) after at least partial deflation and the bringing of the bladder clamp rings together overlies the bottom bead of the cured tire. This ensures that the tire properly remains on the bottom bead ring during stripping from the upper mold half and then the lower mold half,and as the bladder is drawn into the bladder well or bead lift can.

摘要： A dual cavity hydraulic tire press utilizes a single long stroke piston-cylinder assembly vertically positioned substantially in line with the center of gravity of the vertically movable upper mold sections, the latter being supported on the underside of the outer ends of a shallow V-shaped beam which is mounted for vertical movement on a readily removable column or post. In the closed position of the press the top mold cavities are locked to the base of the press by rotatable bayonet locks. Four short stroke hydraulic clamp piston-cylinder assemblies are positioned beneath each bottom mold section to achieve clamping pressure during cure. In one embodiment mechanical stops may be provided to achieve mold height adjustment and to preclude the molds opening significantly upon loss of fluid pressure to the clamping piston-cylinder assemblies. In another embodiment the clamp-piston-cylinder assemblies are mechanically adjusted to obtain the proper position for mold height adjustment. The press includes a safety bar which is supported from the top mold section for part of its movement with the bar being held stationary during initial opening movement of the top molds, and then picked up to be in a position just below extended segment molds if employed. The clamp-piston-cylinder assemblies are provided with extended coolant passages between the clamp actuating fluid and the heat of the mold cavity to preclude degradation of the fluid employed. The isolation of the clamp pressure at four equally spaced points beneath the bottom platen enables the platens and molds to be more efficiently encased with insulating materials not subject to high pressure during cure. The position of the clamp-piston-cylinder assemblies as well as the piston-cylinder assembly opening and closing the press preclude hydraulic fluid contamination of the uncured or cured tires passing through the press. With the present invention, a tire curing press of substantially less weight, envelope and energy consumption can be provided.

摘要： A tire building machine otthe expandable bead lock type employs an elastomeric specially shaped radially expanding bead lock (43) including a shaping and turning bladder (48) which includes an air passage system therethrough. The elastomeric bead lock is confined for radial expansion in an annular outwardly opening chamber (114) in the form of an isos- celestrapezoid in radial section with the elastomeric bead lock being of similar configuration and expanded by direct application of air pressure within the chamber. The configuration of the annular chamber and the bead lock compensate for stretching of the bead lock upon enlargement. The edges of the bead lock atthe axial sides of the chamber are undercutfor flexibility while the walls (70,71) of the chamber are specially coated to maintain the seal. The bead lock incorporates interconnected metallic segment side plates (76, 77) which not only limit the stroke of the moving seal but insure stability axially of the bead and provide the desired concentricity. The bladder is pressurized through an annular air passage system and sealed conduit (137) extending radially through the pressure chamber inside the bead lock.

摘要： tire curing press with an improved loader includes a shaping or center mechanism which includes a vertically movable well (17) on which is mounted the bottom bead or toe ring (16). The press includes a loader of improved design affording precision centering and accuracy which is driven for vertical movement by a ball screw (80) and nut drive which positions the green tire concentric with the upper and lower mold sections and over the bottom bead ring. The loader then moves the green tire downwardly until the lower bead of the green tire reaches a predetermined point touching or fairly closely adjacent the elevated bead ring. Simultaneously, an adjustable pad on the loader contacts the tip of an extended rod of a vertically oriented synchronizer piston-cylinder assembly (147 Concurrently, a sensor is tripped to power the synchronizer piston downwardly and as such piston moves downwardly, the loader follows at a slightly higher speed causing the rotary motor of the ball screw drive to be retarded or stall, thus keeping the loader in contact with the tip of the rod of the synchronizer cylinder assembly. As the synchronizer piston is being powered down, fluid on the underside of such piston is being forced over to the top ports of a pair of beat lift cylinder assemblies (24, 25) causing them to bring the well(17) andtbus the lower bead ring down at the-same speed as the loader is bringing the tire down. In this manner the green tire and lower bead ring are maintained in constant relationship until the bead ring is seated on the lower mold section. The point of bead ring seating provides a physical stop which in turn blocks the synchronizer piston and rod, and thus the loader from further downward travel. This synchronization is accomplished by making the blind end area of the piston of the synchronizing cylinder assembly twice the equal rod end areas of the pistons of the bead lift cylinders.

摘要： A spring finger ply down for a tire building machine comprising an annular array of spring fingers (10), an annular support (11) for the fingers and a constrictable clamp (13) for securing each finger to the support at an axial interference (28, 30) between each finger and the support. The constrictable clamp includes an elastic band (34) stretched circumferentially around the fingers and/or a clamping ring (38) of relatively inextensible material that is adjustably constricted or cinched around the fingers or, if used, the elastic band for holding rigidly or relatively rigidly the fingers to the support. The elastic band is locally radially deformable to permit radial release of the axial interference for easy insertion and removal of a finger without disturbing adjacent fingers.
