Description

Die switching equipment Technical Field The application relates to the technical field of automobile production, in particular to a die switching device. Background The parts of the front door, the rear door, the front cover and the rear cover of the white automobile body, namely the four-door two-cover, are key parts in automobile manufacturing and are manufactured through an efficient door cover flanging production line. At present, a flanging machine system on a welding production line is generally provided with a plurality of die stock positions, and a mode of 1-use n-use is adopted to ensure production continuity and flexibility. When the vehicle type is switched, the system stably moves the die in the flanging machine to the vacant warehouse position through the precise push-pull chain device, and then automatically pushes and pulls the standby die in the other warehouse position into the flanging machine, so that the automatic, rapid and accurate switching of the die is realized. The automatic flow greatly improves the production efficiency and lays a solid foundation for high efficiency, accuracy and intellectualization of automobile manufacturing. However, the existing flanging machine system usually detects the number of the die or the workpiece after the die is switched to the station of the flanging machine, the matching property of the die and the model cannot be confirmed in advance, if the model matching is wrong, the die is required to be switched again, the downtime of the production line is prolonged, and the production efficiency is affected.
