摘要:
Cross bars 18, to which workpiece holders 19 are attached, are provided across a press line L, together with feed beams 14 between which the cross bars are installed and which are suspended from the lift beams 13 and can move freely in the horizontal direction of the press line. A feed and transfer device 52 can move the feed beams freely in the horizontal direction of the press line. A connecting rod 56 connects the feed beams and the rack beam in a freely rotatable manner. A connecting link 60 connects a point in the vicinity of an intermediate portion of the connecting rod to a bracket 58 installed on the rack beam, in a freely rotatable manner. An operating direction changeover mechanism 61 converts the differential movement caused by the curvature of the press transfer motion, produced in the feed beams when the lift beams are raised or lowered, into a horizontal movement in the direction of the press line in synchronism with the raising or lowering of the lift beams.

A trolley is reciprocally moved along a guide. A work support, supported by the trolley, is vertically moved so that the lift mechanism can be made of a compact size, a light weight and highly reliable in operation thereby increasing the processing speed of the processing line and improving productivity.

摘要:
A fuel cut-off device for an internal combustion engine having a fuel supply means into the engine. The device comprises a fuel cut-off means for cutting the supply of fuel to protect the engine from an abnormal rpm rate when the engine speed exceeds a fuel cut-off reference value at a relatively higher speed range. The device further comprises a racing condition detecting means and a means for determining the fuel cut-off reference value to provide a first value for the loaded condition of the engine and a second lower value for the racing condition of the engine. In the racing condition, the fuel cut-off reference value is further progressively reduced.
