Failure recovery method for stamping device of automatic stamping line

The invention discloses a failure recovery method for a stamping device of an automatic stamping line. The failure recovery method for the stamping device of the automatic stamping line comprises the following steps that an action time sequence chart of all devices of the automatic stamping line is drawn, and an interlocking inspection table is established; corresponding action recovery time sequences are made according to different halt positions; the operating condition of the stamping device is monitored, and failure recovery is conducted if the stamping device breaks down, wherein the failure recovery process comprises the steps that information of the current angles of all the stamping devices is obtained, whether a certain stamping device is located in front of a lower dead point or behind the lower dead point is judged, a feeding system is controlled to act according to the position of the stamping device, the stamping device is controlled to act according to the position of the feeding system, whether a board exists in the stamping device is judged, the stamping device and the feeding system are controlled to act according to a predetermined action time sequence, and the stamping device and the feeding system are controlled to act according to the action recovery time sequences for different halt positions. By the adoption of the failure recovery method for the stamping device of the automatic stamping line, the device of the automatic stamping line can be recovered to the initial position safely and rapidly.
