The specific embodiment:
Further specify particular content of the present utility model and embodiment below in conjunction with the accompanying drawing illustrated embodiment.
As shown in Figure 2, curved surface part flexibility of the present utility model rises and pulls into that the shape device comprises fuselage ring, prestretched mechanism, end clamp mechanism, rising pulls into shape mechanism and restructural multiple spot mould.
Described fuselage ring adopts integral type fuselage ring 9, it is support and the load mechanism of building mortion, for proof strength and rigidity, integral type fuselage ring 9 is welded by steel plate, comprises support frame, prestretched platform and three parts of removable workbench.The prestretched platform divides and is made up of left and right sides two parts in the same plane, and prestretched and clamp mechanism are installed on it; Removable workbench 12 moves up and down guide rail 11 by workbench and is installed on the vertical support frame up and down, removable workbench 12 bottoms are connected with the piston rod of main thrust hydraulic cylinder 10, push the work forward platform and the restructural multiple spot mould 7 that is installed on the platform moves up and down by main thrust hydraulic cylinder 10, finish part and rise and pull into the shape process.
Described prestretched and clamp mechanism by leading screw 6, about revolve screw 4, leading screw supporting seat 3, stretching clamp 5, clamping hydraulic cylinder 8 and servomotor 1 and reductor 2 is formed, realizing rises draws before the end of plate clamp and the control of prestretched amount.By leading screw supporting seat 3, left-right turning screw rod 6 is fixed on the integrated fuselage framework, and front and back respectively have one group, the stress balance when guaranteeing prestretched.The screw thread of left-right turning screw rod 6 revolves design about being, namely an end is that left hand thread, the other end are right-handed thread, is separately installed with on the leading screw of two ends to revolve screw 4 about corresponding, and by the rotation of leading screw, two cocainine mothers' 4 synchronous opposite direction drives about realization.One cover leading screw, screw are respectively arranged before and after the expansion pulling device, and the common stretching clamp 5 that is installed on the screw that drives is realized side-to-side movement.The rotation of left-right turning screw rod 6 is driven by reductor 2 by servomotor 1, and described servomotor can be AC servo motor, also can be DC servo motor.Before and after two left-right turning screw rods 6 driven by two servomotors 1 respectively, pull into driving force in the shape process thereby be provided for prestretched with rising.Two cover left-right turning screw rods 6 must guarantee rotation synchronously before and after in the described prestretched mechanism, and it is realized by the servomotor Synchronous motion control synchronously.The Torque Control pattern of described servomotor 1 realizes the tensile force control of clamp, its position control mode is realized the prestretched amount control of plate, its speed control mode is realized the prestretched speed control of plate, pulls into La Bianli size in the shape process thereby effectively control the plate pretensioned state and rise.
About stretching clamp 5 comprises two groups, be respectively applied to the clamping on two end edge edges of plate.Stretching clamp shown in Figure 1 by 7 independently clamp form, all 7 clamps are installed on the same fixed axis, and can rotate along fixed axis, thereby guarantee to pull in the shape rising, along with the top of going up of main thrust hydraulic cylinder 10, the jaw of stretching clamp 5 and the arm-tie material edge tangentially state all the time that risen.Opening with locking of stretching clamp 5 realized by the clamping hydraulic cylinder 8 that is mounted thereon.According to the function needs, clamping hydraulic cylinder 8 can be realized whole clamping force control by switch valve, proportioning valve or servo valve control, also can realize the power control of single clamping hydraulic cylinder, draws the limit effect thereby improve.
Describedly rise that to pull into shape partly be one of principal organ of this device, it promotes removable workbench 12 up and down by main thrust hydraulic cylinder 10, realizes moving up and down of removable workbench.About being fixed in, restructural multiple spot mould 7 on the moveable platform 12, realizes moving up and down with platform.Removable workbench 12 is by being installed on the integrated fuselage framework 9 up and down, moves up and down guide rail 11 by workbench guiding when moving up and down is provided.
Described main thrust hydraulic cylinder 10 is upwards promoted can move up and down workbench 12 and is made restructural multiple spot mould 7 near by the plate of prestretched by servo electromagnetic valve control, under the effect of last top restructural multiple spot mould 7 workpiece is risen and pulls into shape.The different control models of main thrust hydraulic cylinder 10 realize that different rising draw the control parameter.Force control mode can be controlled going up in the drawing process process that rises and push up the pulling force that rises; The displacement control model can be controlled top displacement on the multiple spot mould, the amount of drawing thereby the control plate rises; Speed control mode can be controlled top speed, the pulling rate rate thereby control is risen.
Restructural multiple spot mould 7 is arranged by several highly adjustable drift element bodies and is formed.The height of each drift element body can be by the computer numerical control adjustment, and its implementation can drive the square body realization of internal thread by the leading screw rotation, also can pass through hydraulic cylinder, cylinder or linear electric motors and realize; Its arrangement mode can closely be arranged as required, also can arrange according to certain intervals; The layout of drift element body can be matrix-style, also can be to be honeycomb arrangement.After all drift element bodies were adjusted to needed height, the machined surface profile that its end forms replaced unitary mould to be used for rising pulling into shape.
Described restructural multiple spot mould 7 can be replaced by rise drawing-die tool or simple die of entity, and this device can realize that equally rising of curved surface part pulls into shape.
Use this utility model device and rise when pulling into the shape curved surface part, at first plate is put among the clamp of the left and right sides, set the clamp clamping force according to material behavior and the requirement of the amount of drawing that rises; Control servomotor then and rotate synchronously, plate is pre-stretched to setting value; Start the main thrust hydraulic cylinder, promote multiple spot restructural mould and move upward, the prestretched plate rises and moves needed curve form to, can obtain the three-dimension curved surface part that needs after the unloading.When the geometry of target curved surface part, sheet thickness, material behavior etc. change, only needing to change technological parameters such as the profile of multiple spot mould and the pulling force that rises, the amount of drawing that rises automatically fast according to digital-to-analogue can be shaped again fast, and the flexibility that realizes curved surface part rises and draws.
This utility model can realize that rising of different materials thin plate such as aluminium alloy, titanium alloy, steel plate pull into shape.Can be used for rising of aircraft skin class part and pull into shape, also can be used for high speed motor car group aluminum alloy outside plate part forming, also be suitable for the flexibility manufacturing of personalized aluminium alloy in the modern architecture, stainless steel exterior wall curved surface simultaneously.
