The Design And Research Of The Three Stations Vertical Injection Equipment For Rubber Stator Of Screw Drill And Screw Pump And Simulation Of 3D Dynamic Process

Screw drills and screw pumps are more and more widely used to satisfy the needs of the production of oil field ,because they have many advantages ,such as they are cheaper ,consume less energy ,and are more convenient to assemble and debug and rubber stators are their hard-core components .But the existing equipments which are used to make rubber stator have many disadvantages: firstly ,the leptosomatic stator will make a obvious bending deflection when they are injected; secondly, pressure equipment will bring gauche moment because of the non-superposition in axes between the pressure equipment and injection machine; thirdly ,the face of locomotive die is paralleled to the axial force brought by injection machine, which debase the equipment's life-span. Screw drills or screw pumps are seriously restricted by the traditional backward producing method.By the research on the principle of the rubber injection molding equipments and the advantages and the disadvantages of the molding equipments of screw pumps rubber stator ,on the base of one step principle and the power consume of press equipment ,we designed a new machine which named three stations vertical injection equipment for rubber stator of screw drill or screw pump .The following work will be done:1. Vertical injection is first used in injection machine which is used in producing rubber stators .this technique overcomes the problems of bending deflection, predigests technical course and improves the eligible rate and productivity.2. The three stations locomotive equipment is fist used in injection machine...
