摘要： The present invention provides a method of manufacturing a rocker arm, having a process of rough processing, in which a metallic stock is subjected to compression-forming by cold forging to form a connecting portion, side wall lower portions of two side wall portions, and two projecting portions projecting beyond a rocker arm width outwardly from the side wall lower portions, and to form, at tip ends of the side wall lower portions, two stem guides projecting downwardly lower than a pat surface level of the connecting portion, a process of formation of a side wall, in which at least a part of the two projecting portions is subjected to ironing processing to form side wall upper portions of the two side wall portions, thereby forming the two side wall portions accommodated in a rocker arm width, and a process of working of a stem guide, in which the two side wall portions are subjected to ironing processing from outer surface sides, thereby increasing a projection height from which the stem guides project downwardly.

摘要： The present invention discloses a standoff control method and an apparatus for a plasma cutting machine capable of quickly correcting a deviation of the standoff with respect to a set value, keeping constant the standoff even if the cutting speed changes, preventing deterioration of the working efficiency even if a double-arc is generated, and properly detecting the use limit of the electrode. Standoff correction computing device (28) includes a reference voltage computation setter (36) for outputting a reference voltage between a workpiece to be cut and an electrode or a nozzle with respect to a predetermined standoff, an error computing device (37) for calculating the deviation of said detected voltage with respect to the reference voltage, and a correction quantity computing device (38) for outputting a vertical repositioning speed signal for the torch in accordance with the degree of the deviation. An electrode consumption/standoff detector (34) can be provided which outputs, to the error computing device (37) a standoff signal which is obtained by correcting for the degree of rise of the voltage which has taken place due to the consumption of the electrode (12).
