Abstract

A press load measuring apparatus for a press machine of 1-point type includes: a plurality of strain gauges attached to the respective columns of the press machine, the plurality of strain gauges detecting respective strains generated in the respective columns in association with a press load acting on the slide; a bending moment calculator configured to calculate bending moments acting on respective columns based on an angle formed between a direction of movement of the slide and the connecting rod; and a press partial load calculator configured to calculate press partial load signals corresponding to the respective columns, an impact of bending strain components caused by the bending moments included in the strain signals being eliminated from the press partial load signals based on the bending moments acting on the respective columns detected by strain gauges attached to the respective columns.
