Abstract
The invention discloses a method and device for die blockage automatic protection of a powder forming machine. Two detectors are arranged on the powder forming machine, one detector is used for detecting a state of a pressing machine, and the other detector is used for detecting a falling stroke of a lower sliding block mechanism of a die. If the detector for detecting the state of the pressing machine detects that the pressing machine is already in a stuffing state and the stroke detected by the detector for detecting the falling stroke of the lower sliding block mechanism of the die is not in pace, people can judge that die blockage occurs, and at the time, the pressing machine is shut down through a control mechanism to be overhauled. The state of the pressing machine and the conditions of a demolding mechanism are detected through two detection mechanisms respectively, whether die blockage occurs is determined by comparison, die blockage can be effectively avoided, and safety in automated operation can be further improved.
