Horizontal flanging machine

The invention discloses a horizontal flanging machine which comprises a rotating mechanism installed on a rack, a limiting mechanism used for bearing and limiting a workpiece, pressing wheel mechanisms arranged at the two ends of the workpiece respectively and a flanging mechanism used for flanging machining. The flanging mechanism is at least composed of an installation base, a driven wheel, a pre-flanging wheel and an edge pressing wheel, wherein the driven wheel, the pre-flanging wheel and the edge pressing wheel are sequentially arranged on the installation base from top to bottom, and thedriven wheel, the pressing wheel mechanisms and the rotating mechanism are matched to drive the workpiece to rotate. The workpiece is limited and fixed through the limiting mechanism, the driven wheel and the pressing wheel mechanisms, it is effectively guaranteed that the workpiece cannot deviate or disengage in the machining process, potential safety hazards in use are reduced, meanwhile, the edge of the workpiece is s
