2 results about "Electrorheological fluid" patented technology

A rapid molding method based on an electrorheological fluid, and an apparatus thereof are provided. The electrorheological fluid is jetted to a deposition base station with electric field, the electrorheological fluid is rapidly cured through utilizing an electrorheological effect, and the electrorheological fluid deposits on the deposition base station layer by layer to construct a three dimensional entity; a liquid storage container, a driving pump and a nozzle are sequentially communicated through a pipeline to form an electrorheological fluid conveying path; two control lines are set by a computer, a first control line controls the flow of the driving pump, and a second control line controls the three dimension movement of the nozzle through a servo mechanism; and electrodes which comprise an anode and a cathode closely adhere to two sides of a model to be deposited on the deposition base station to provide the electric field required by the curing of the electrorheological fluid. The apparatus which utilizes the electrorheological effect of the electrorheological fluid and utilizes the electric field to replace a temperature control module and a constant temperature environment in traditional fusion jet rapid molding has the advantages of simple structure, substantial reduction of the cost and energy, and realization of micromation; and the method and the apparatus can be applied to fields of prosthesis models, industrial design, mechanical manufacturing, three dimensional scene display, entertainment and art, and the like.

The invention relates to the technical field of new energy automobile part machining, and discloses a special-shaped part clamping device for new energy automobile part production. The special-shaped part clamping device for new energy automobile part production comprises a clamping table, an electromagnet is fixedly connected to the inner wall of the middle of the clamping table, a non-magnetic material is fixedly connected to the inner wall of the middle of the clamping table, and a movable groove is formed in the inner wall of the middle of the clamping table. A liquid storage cylinder is movably connected to the inner wall of the movable groove, a reset spring is fixedly connected to the outer side of the liquid storage cylinder, and a piston is movably connected to the inner wall of the middle of the liquid storage cylinder. According to the special-shaped part clamping device for new energy automobile part production, the electromagnet drives a magnetic block to operate, the magnetic block drives the piston to move, and then the clamping table and a deformation sleeve are used in cooperation, so that the effect of clamping a special-shaped part is achieved. The electromagnet is powered on to generate a magnetic field, and the magnetic block drives the piston to move under the action of repulsive force. Electrorheological fluid is extruded to fill the interior of the deformation sleeve along the inner wall of the liquid storage cylinder, and at the moment, the deformation sleeve deforms and is attached along the surface of the part.
