The common that wringing dragon is helix conveyer says, the level that applies to grain or farinaceous stock is carried, tilt carry, perpendicular carry wait for a form. Carry a distance to differ and differ according to machine form, go to 70 meters from 2 meters commonly. The lamina that wring dragon is the main component that wrings dragon, next small make up those who be everybody introduction to wring dragon lamina to make flow and method: Input external diameter of the lamina that wring dragon, internal diameter and lead first before treatment wrings dragon lamina (pitch) , automatic computation gives what what need to lay point of view of makings external diameter, internal diameter, cut, computation goes out after developing a plan, the semifinished product that the basis develops a graph to issue good place to require an amount (should leave mental allowance) . Will all semifinished product is folded together, with spot welding join forms state of a cylinder, lathe is machined on inside, external diameter requires measure to place. Ravel semifinished product individual, edge radial is cut open, hold cut both sides to be pulled open to axial with forceps or spanner clip, pull open 20 Mm of about 10 ～ can, all lamina are in weld of butt joint of end to end in cut, in * with a two side after Zui each solder a ring tab, secure ring tab of one aspect of the matter, another ring tab is hanged in heavy calabash rises commonly usedly to go up in the workshop at ordinary times, pull open blade the pitch that needs to place slowly. the new lamina with eliminate ring tab, smooth burnish, weld. The computation that wrings Long Xie should have the following: Axial diameter: D leaf external diameter: D lead: P computation asks referenced figure CNC MillingCNC Machining
