EQUIPMENT FOR TESTING AND REPAIRING BLANKS Russian patent published in 2000 - IPC

FIELD: metallurgical industry branches, namely, quality and size control of tubes, their material testing. SUBSTANCE: equipment for testing and repairing blanks includes charging grid, discharging grid, apparatus for testing and repairing blanks and transporting roller table connecting all said units. Apparatus for testing and repairing blanks is in the form of two parallel-arranged rollers and driven levers for raising blank. One roller is mounted with possibility of raising-descending by means of pneumatic cylinder. Second roller is mounted stationary. Both rollers are driven ones. Blank by means of driven levers is placed onto stepped driven rollers, one roller is raised relative to another roller by 20-30 degrees. Then raised roller descends to horizontal position, both rollers are driven to rotation and blank is tested. After termination of blank testing the same roller raises by 40 degrees, blank rolls down onto raised levers and it is placed onto roller table at descending levers. EFFECT: enhanced safety of operator, shock-free reception and rolling down of blank and therefore enhanced reliability and increased useful life of equipment. 8 dwg
