Description

Thin plate based on vibration of ultrasonic wave is combined micro-forming device
Technical field
This utility model relates to a kind of thin plate and is combined the device and method of microsecond delay, belongs to chill punching of sheet metal forming technique field.
Background technology
Microsecond delay refers to that the size of formation of parts at least two dimensions between macro-scale and micro-scale in i.e. 0.01~1mm, require the definition of accuracy of the product forming between 0.01~1mm simultaneously.With electronics industry and the big industry high speed development as representative of precision optical machinery two so that the needs of miniaturization product are the most vigorous.But along with going deep into of research, find microsecond delay technology and traditional plastic forming technology incomplete same, many phenomenons different from macroscopic view Plastic Forming and feature is always occurred in that i.e. " scale effect " in the course of processing, it is thus impossible to simply traditional plastic Forming Theory is grafted directly in micro-forming.Reduction due to size so that the flow stress-strain stress relation of material, frictional behaviour, former, instrument, accessory etc. produce change, bring series of problems to microsecond delay, such as resilience, burr, pad pasting, surface quality etc..In recent years, some new processes are applied in micro-forming.Although these new meso-scale sheet moulding techniques have advantage that traditional handicraft do not possesses as only needed monolateral mould, being prevented effectively from wrinkling, decreasing rebound, raising forming limit etc., but there is also some drawbacks, during as shaped cylindrical member, along with the increase of aspect ratio, the form accuracy at workpiece straight wall position it is difficult to ensure that;Baroque microsecond delay part, geometric accuracy is difficult to meet too.In order to solve the problem of the above-mentioned existence of meso-scale sheet moulding, urgently seek a kind of method that can be effectively improved meso-scale sheet moulding performance.
Plate flexible die forming is to utilize certain material to replace rigidity punch or die as the power transmission medium of sheet forming; again by a rigid die as die or punch; under power transmission medium effect, make plate and punch or the laminating of die shape face, thus form punch or shape that die shape face is retrained.State characteristic according to medium generally can be divided into solid-state soft mode, semisolid soft mode and liquid soft mode three major types.Compared with traditional plate cold forming, flexible die forming has that drip molding surface quality is good, be beneficial to Complex Parts and shapes and resilience little, low cost little, wrinkling and the advantage such as the cycle is short.Solid state medium in the shaping of solid-state mantle is owing to having good filling capacity and mobile performance, and chemical stability is good, to improving drip molding surface quality, improve patch mould and forming accuracy etc. and have clear superiority, therefore, solid state medium flexible die forming be a kind of effectively, and feasible sheet forming new method and means.Although flexible die forming technology has plurality of advantages, but the inside plastic force of solid state medium relies on outside plastic force, its filling capacity and mobile performance are bigger on plastic force impact, during the sheet forming that especially intensity is higher and shape is more complicated, it is easily caused the defects such as the form accuracy step-down of drip molding, pad pasting variation and resilience change are big.
Nineteen fifty-five, Blaha and Langenecker is to introducing supersonic vibration in zinc monocrystalline stretching experiment, and observes that the deformation force of material the phenomenon of anticlimax occurs i.e. " ruckbildung ", also referred to as Blaha effect.To this end, many scholars are for the supersonic vibration theoretical mechanism to Plastic Forming, and the application that supersonic vibration is in the plastic forming process such as wire drawing, drawing, sheet forming, spinning has carried out numerous studies.In traditional metal blank plastic forming process, introducing supersonic vibration technology, the plastic force being possible not only to reduce between workpiece and mould is " skin effect ", can also reduce the flow stress of plate i.e. " bulk effect " simultaneously.Therefore, supersonic vibration assist formation technology can be effectively improved the advantages such as the forming property of plate, the workpiece surface quality of improvement, decreasing rebound.But for the forming of large plate, owing to being restricted by factors such as workpiece and die size, forming device and weight, existing supersonic vibration technology is difficult to meet the forming technology of large plate.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of thin plate based on vibration of ultrasonic wave to be combined micro-forming device, can be effectively improved thin plate microforming behavior and quality in conjunction with solid granulates medium flexible die forming and the technical advantage of supersonic vibration assist formation.
For reaching above-mentioned purpose, thin plate based on vibration of ultrasonic wave of the present utility model is combined micro-forming device, including base plate, it is characterized in that: on described base plate, be provided with at least two support bars, at least two nitrogen springs it are additionally provided with on described base plate, it is hung with working chamber on the plunger of described nitrogen spring, described support bar is provided above the horn fixed plate mated with described working chamber, described horn fixed plate is arranged in described working chamber, many horn it are provided with in described horn fixed plate, also include supersonic generator and the transducer being attached thereto, described transducer and described horn fixed plate Flange joint;Being provided with solid granulates medium in working chamber more than described horn fixed plate, described working chamber is provided above upper mold.
The height of described horn and quantity are adjustably arranged in horn fixed plate.
The edge of described working chamber upper surface is fixed with blank holder, and described nitrogen spring is connected with described working chamber by described blank holder.
This utility model additionally provides the described device of use and carries out the method that thin plate is combined microsecond delay, including: first plate is positioned on blank holder, the upper mold that is installed on press ram is descending to be contacted with plate, under the pressure-pad-force effect that nitrogen spring provides, compress plate, move downward execution drawing and forming technique;Start at drawing and forming, during, terminate in three phases, at least one stage opens supersonic vibration function;Then upper mold rises, and nitrogen spring has resetted die sinking.
Compared with traditional forming technique, this utility model is contacted with plate by solid granulates medium and realizes soft punch function, impact on drip molding surface quality when avoiding rigid convex contour forming, when utilizing the advantage of solid granulates media flow performance and filling capacity to the shaping of complex-shaped workpieces, there is good pad pasting performance and be effectively improved the form accuracy of workpiece, simultaneously, owing to using solid granulates medium as the most monolateral mould of soft punch, eliminate mould processing device and the technique of some of complex, save the cost of Forming Equipments;This utility model combines supersonic vibration technology, can improve and improve solid granulates media flow performance when shaping and filling capacity further, it is beneficial to improve the shape complexity of Forming Workpiece, in addition, make solid granulates medium produce vibration with the contact surface of plate under supersonic vibration effect, can effectively suppress the resilience problem of drip molding.
