To provide a pressure detection device which detects an applied pressure acting on a workpiece without directly receiving a processing pressure of a pressurizer.SOLUTION: A pressure detection device 30 detects a processing pressure with which a processing head 9 acts on a workpiece 2 placed on a pedestal 3 of a pressurizer 1, along a Y-axis direction perpendicular to a top surface 14 of the pedestal 3. A fixed support member 32 is fixed to a movable plate 5 of the pressurizer 1 and receives a driving force of the pressurizer. A strain transform unit 33 is fixed between the fixed support member 32 and the processing head. A buckling detection unit 40 capable of detecting a strain variation due to buckling of the strain transform unit is placed in a position eccentric from a shaft center line of the strain transform unit 33.SELECTED DRAWING: Figure 1 【課題】加圧機の加工圧力を直接受けることなしにワークに作用する加圧力を検出する圧力検出装置を提供する。【解決手段】圧力検出装置３０は、加工機１の台座３に載置されたワーク２に対し、台座３の上面１４に対し垂直なＹ軸方向に沿って加工ヘッド９がワーク２に作用する加工圧力を検出する。固定支持部材３２は、加圧機１の可動プレート５に固定され、加圧機の駆動力を受ける。歪変換部３３は、固定支持部材３２と加工ヘッドとの間に固定される。歪変換部の座屈による歪変動量を検出可能な座屈検出部４０は、歪変換部３３の軸心線から偏心した位置に設けられる。【選択図】図１
