The aluminum alloy pre-forging heating furnace is used to heat the aluminum alloy workpieces before stamping. The internal workpiece transmission generally adopts the form of chain plates, and the discharge position generally adopts an inclined dumping plate structure. The top of the inclined dumping plate is docked with the end of the chain plate transmission structure. During the transmission of the workpiece, due to uneven arrangement and other reasons, it may fall to the outside of the dumping plate.
