とする圧造成形機における圧造異常検出装置。 A forging die is fixed to the machine base, a forging punch is installed in front of a ram that reciprocates toward the forging die, and drives the material into the forging die. A forging abnormality detection device for a forging forming machine, the forging abnormality detecting device having a knockout pin means for retracting when the forging punch is pushed in and pushing out the material by moving forward after the forging punch starts to retreat, the forging abnormality detection device a switch means for outputting an output signal upon detecting that the knockout pin means has retreated by a predetermined amount or more; and a reference signal for outputting a reference signal during a predetermined period during which the forging punch moves from a forward process to a backward process. outputting means; and determining whether or not an output signal indicating that the knockout pin means has retreated by a predetermined amount or more is outputted from the switch means while the reference signal is being outputted by the reference signal outputting means. What is claimed is: 1. A heading abnormality detection device for a heading forming machine, comprising: abnormality determining means for determining an abnormality based on the following.
