A forming process and apparatus for producing a composite pipe by friction welding

Abstract

The application belongs to the field of mechanical design and material processing, and particularly relates to a forming process and equipment for preparing a composite pipe by using friction welding, the forming equipment comprising a rack, the rack comprising a bottom plate, a lower base and an upper base being supported above the bottom plate, two mounting racks being symmetrically arranged on one side of the upper surface of the upper base, a rectangular hole and a circular mounting hole being arranged through the middle of the upper base; a rolling mechanism and a rotary friction extrusion mechanism for clamping metal bars being arranged on the left and right sides of the upper base respectively; the forming equipment further comprising a clamping mechanism arranged between the rolling mechanism and the rotary friction extrusion mechanism, a stamping mechanism arranged between the two mounting racks, a cutting mechanism arranged above the clamping mechanism, and a die mechanism arranged below the stamping mechanism; the clamping mechanism, the rotary friction extrusion mechanism, the die mechanism, the cutting mechanism, the rolling mechanism and the stamping mechanism are cooperatively matched to realize stable clamping and continuous processing of the workpiece.
