Abstract (en)
[origin: EP3421176A1] A shot peening device (50) includes a turntable (79) which rotates about a revolution axis (X1), holding mechanism (81, 82) which moves with the turntable (79), pressure mechanism (93) which compresses a coil spring (1), rotation mechanism (100) which rotates the coil spring (1), projection mechanism (57) which projects shots to the compressed coil spring (1), load cell (96, 97) which detects a load applied to the coil spring (1), and controller (98). A signal output from the load cell (96, 97) is input to the controller (98), and the controller (98) detects a chronological change of the load applied to the coil spring (1) during the shot peening.
