STAND FOR DETERMINING WORKING CYCLE PARAMETERS OF PNEUMATIC PUNCH Russian patent published in 1997 - IPC

Abstract RU 2098568 C1

FIELD: testing of pneumatic percussion-type machines. SUBSTANCE: stand has bed for fastening pneumatic punch to be tested, punch motion control detectors positioned in spaced relation one relative to the other and time interval detecting unit. Punch motion control detectors are made in the form of magnetic heads, with space between outer magnetic heads exceeding maximum allowable value of inoperative motion of punch. Magnetic heads may be arranged in four places. Base may be provided with thrusts and magnetic heads may be positioned between thrusts. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 3 cl, 3 dwg
