"Life Is Just Fine, When There Is Wine".A WINE BOTTLE STOPPER, which uses the radial deformation of a hollow cylinder - made of silicone - for sealing the inner diameter of the bottle neck.The radial deformation can be reached by the compression of the hollow tube in axial direction.The axial movement is realized by a metrical thread M8, with the standard pitch of 1.25 mm.The most interesting component of this design is for sure the knob with the inner thread.This component is made of three parts and two welding joints.After welding the parts, the component has to be machined to reach the final dimensions. At least a chroming process is necessary to reach a beautiful shiny appearance.Notes:The threads are modeled with theoretical values and have not any clearance between the bolt and nut.The upper and lower half of the knob are made of deep drawn brass with a thickness of 1 mm.The welding joints are modeled as two seperate parts and are therefore "dummies" in the knob's assembly.As my marginal note:Brass is a "modest" material, because it is often hidden under coatings like chrome, nickel, silver or others. ;-)The model is available in following data formats:STEP-file (.stp) of the complete assembly and all native files (.prt) and (.asm),together in a (.zip)-folder, for users of »PTC Creo Parametric 2.0«A big thank you to » James Saunders «, for his model "Wine Bottle".
