TYRE STUDDING SEMIAUTOMATIC MACHINE, STUD FITTING DEVICE AND ITS HEAD, AND METHOD OF TYRE STUDDING Russian patent published in 1999 - IPC

FIELD: tyre industry. SUBSTANCE: semiautomatic machine has bed frame with post provided with C-shaped bracket. Thrust unit is installed in lower arm of C-shaped bracket for deflection from post and fixing in preset position. Thrust unit has stop tongue adjustable in height and frame coupled with tongue and also adjustable in height on axle of which guide rollers are installed for carrying tyre to be studded. Device for driving studs into tyre holes is coupled with post. Head of device is connected by pipeline with feeding device installed on separate post above stud driving device. feeding device provides directional feeding of studs. Device for driving-in antiskid studs is secured on upper arm of C-shaped bracket by means of adjustable damper unit. Pneumocylinder unit of device consists of first power cylinder and second power cylinder serving as piston of first power cylinder and provided with spring-loaded piston with pusher to force stud through head coupled with housing of second power cylinder. Control spaces of both power cylinders communicate with pressure source through distributing device mounted n end face part of housing of first power cylinder. To provided change-over of operations, spool of distributing device is mechanically or pneumatically coupled with piston of first and second power cylinders. EFFECT: increased service life of parts and units of semiautomatic machine, enhanced reliability of machine and quality of stud driving at increased capacity. 15 cl, 9 dwg
