Abstract

This invention discloses an automatic feeding type hot-push elbow machine, comprising: an automatic feeding unit including a storage bin, a single-pipe temporary storage tank, and a pushing mechanism; a continuous pushing unit including the core rod, with a die head disposed at the front end of the core rod, the core rod passing through a fixed wall, a movable wall, and a supporting wall arranged sequentially, the die head being disposed on the front side of the supporting wall, a hydraulic cylinder disposed on the fixed wall, the piston rod of the hydraulic cylinder being connected to the movable wall, for pushing the steel pipe located on the front side of the movable wall forward; and a heating and forming unit for hot-processing the steel pipe pushed to the die head into an elbow, including a heating ring disposed on the outside of the die head, the heating ring being connected to a position adjustment mechanism. This invention can realize automatic and orderly supply of steel pipes, significantly improving feeding efficiency and consistency; moreover, it can effectively avoid positional interference between the elbow discharge and the heating ring, improving the elbow forming quality and the continuous stability of equipment operation.
