Extrusion and chemical polishing synchronous device and process for aluminum profile die

The invention provides an extrusion and chemical polishing synchronous device for an aluminum profile die and a process of the extrusion and chemical polishing synchronous device, and relates to the field of aluminum profile machining. The polishing structure is fixedly installed on the right side of the extrusion forming body, a moving part is installed in the polishing structure through an inner rod, guide plates are fixed in the moving part, flow guide holes which are evenly arrayed are formed in each guide plate, the side edge of the bottom of each flow guide hole is of an inclined structure, and an insertion structure is fixed to the outer side of each guide plate. The guide plate moves up and down in the polishing structure, the bottoms of the flow guide holes of the guide plate extrude the polishing solution, the polishing solution flows inwards through the flow guide holes, then the triangular plate controls the polishing solution to flow upwards, the polishing solution impacts the aluminum profile, t
