Punching die for passenger car air conditioner shell production

The punching die for the passenger car air conditioner shell production comprises a bottom plate, the upper surface of the bottom plate is fixedly connected with a supporting column, the top end of the supporting column is fixedly connected with a top plate, the lower surface of the bottom plate is fixedly connected with supporting feet, and the lower surface of the bottom plate is fixedly connected with a box body. A hydraulic rod is fixedly connected to the lower surface of the top plate, lifting mechanisms are fixedly connected to the left side wall and the right side wall of an inner cavity of the box body, and clamping mechanisms are movably connected to the interiors of the lifting mechanisms. According to the punching die for passenger car air conditioner shell production, the clamping mechanism is installed, the clamping mechanism can fix a workpiece needing to be machined, the situation that the punching precision is reduced due to the fact that the position of the workpiece deviates during punching
