An adjustable diameter circular machine manufacturing technology

Steel coil in the course of carriage, steel roll shaft end need to use cardboard protection, the shape of the board should correspond to coil, therefore, need to hard support plate, round ring formation, existing technology USES the manual method, the template with a knife cut, not only work efficiency is low, and prone to accidents, here small make up will be analyzed an adjustable diameter circular machine manufacturing technology. An adjustable diameter roll forming machine, including the drum, the drum is equipped with a circular support platform, support platform and sets the tool on inner ring and outer ring above cutters and roller; Pressure roller set in the cutting tool on cutting tool between the inner ring and outer ring, inner ring and outer ring set of tools in support from the party, tool under the corresponding to the inner ring on the inner ring, cylindrical and under external circular knife on the edge of the sword; The circular knife, knife, cylindrical on roller with screw thread connection; Internal and external circular knife under all connected with the screw thread; Screw on the screw end is equipped with the driven pulley, the driven wheel and the driven wheel meshing; The driven pulley and driven gear, driving wheel and motor output fixed; Support platform equipped with inner ring, inner ring and outer ring of tools on cutting tool, cutting tool under the outer ring of the corresponding cutting tool hole. On the inner ring, inner ring and outer ring of tools on cutting tool, cutting tool of outer ring and roller have threaded hole, thread Kong Xuan under the screw or bolt; Under the inner ring on the cutter, circular knives, knife on the cylindrical, under external circular knife, roller ends with the lock nut. The utility model has the advantage that: due to the inner circle on the cutter, on the cylindrical inner circle under the cutting tool, cutting tool, under the cylindrical cutter is threaded connection under the screw or bolt, so can adjust each cutter location, and then adjust the inside and outside the radius of the circle.
