Abstract
A device used for continuous dieless forming of metal sheets comprises two industrial mechanical arms (2), forming tool heads (3), a sheet clamping bracket (7) and a platform (1), wherein, the sheet clamping bracket is fixed in the middle part of the platform; the industrial mechanical arms are arranged on two sides of the sheet clamping bracket (7) respectively; and the two forming tool heads are connected with the industrial mechanical arms (2) at one end, and the other ends thereof are in contact with the sheets on the sheet clamping bracket (7). In the operation, the forming tool heads (3) are driven by the industrial mechanical arms (2) to move and act on the two sides of the sheet respectively, so that not only the forming of integral sheet is realized, but also the forming or shape correction of local areas is realized. The dieless forming of metal sheet parts with raised and sunken curved surfaces has greater processing flexibility. The device with simple structure and low use cost is suitable for the forming of small-lot parts such as automobile covering pieces with various complex curved surfaces, casings of aerospace vehicles and the like.
Description
One, technical field
The present invention relates to field of machining, specifically is a kind of mouldless shaping device.
Two, background technology
Usually in traditional mode of production, the sheet metal part of making complex-curved shape need adopt punch and die to process.But punch and die to manufacture and design the cycle long, the cost height so this device is adapted to produce in enormous quantities, is not suitable for the production of single and mini-batch production part and the trial-production of new product prototype system.Simultaneously, the kind of traditional moulds formation of parts and complexity all have significant limitation.And, because resilience is inevitably,, also need to spend the plenty of time in the actual production and manpower is revised repeatedly to die and punch in order to compensate resilience to the influence that the formation of parts precision produces in sheet forming process.Thereby, in order to reduce cost, to shorten the production cycle, need a kind of mould that promptly do not need, can compensate the new building mortion of resilience simultaneously again effectively.
At publication number is in the patent of invention of CN1320497, has proposed a kind of progressive molding method and apparatus.In this invention, the plate that is cut into reservation shape is installed in the mould top, the plate bottom is the state of base support, plate is subjected to the pointwise of forming tool head up and constantly pushes, and finally makes the material progressive molding.At publication number is in the utility model patent of CN2439348, has proposed a kind of multifunctional numerical control molding machine.It is with processed plate frame above a core, clamp with pressing plate around the plate.This pressing plate can slide up and down along guide pillar.Add man-hour, this device is fixed on the three-head milling machine, control a forming tool head with the procedure of establishment in advance and plate progressively is pressed against on the core, finally be configured as a part to walk the isocontour mode of part section.There is certain limitation in the asymptotic building mortion of this single head, can only process the metal blank part that only comprises convex or outer concave shape, and needs to be equipped with special-purpose former.On " mechanical engineering journal " o. 11th in 2005, Mao Feng etc. have proposed a kind ofly to replace cores to support processing unit (plant) at the point that key position supports plate with several fixing push rods.This technology can realize the mouldless shaping on certain meaning.But support building mortion certain limitation is arranged, occur formation of parts unstability and metaboly easily, and the shape of energy formation of parts is comparatively simple at this point.
Three, summary of the invention
Simple for the part shape that overcomes the shaping that existing apparatus exists, need core and baroque shortcoming, the present invention proposes a kind of mouldless shaping device.
The present invention is a kind of mouldless shaping device, comprises two parts.A part comprises fixed platform, two industrial machine hands and control system thereof, two forming tool heads.Another part is the plate holding frame, comprises plate gripper frame and base plate.
Be evenly distributed with parallel standard T-slot on the table top of platform, the direction of groove is perpendicular to the plate holding frame.Plate holding frame appearance and size is with the appearance and size of formed thereby plate; This plate holding frame is fixed on the middle part of platform.Two industrial machine hand branches are listed in the both sides of plate holding frame.
The diameter of forming tool head is 7～10 times of formed thereby sheet thickness.One end of forming tool head is connected with the industrial machine hand, and the other end contacts with plate, and with the end of plate contact jaw be ganoid semicircle cambered surface.
The plate holding frame comprises rectangular base plate and plate gripper frame.Base plate is connected with fixed platform.
The plate gripper frame is positioned at the middle part of base plate; The plate gripper frame is three-back-shaped frame, and its appearance and size is with the appearance and size of the plate of formed thereby.Be evenly equipped with the fixedly screw hole of plate along plate gripper frame periphery, plate to be formed is fixed on the plate gripper frame.The plate gripper frame is perpendicular to base plate, and is weldingly fixed on the base plate.
The advantage of the said progressive molding device of the present invention is:
(1) in this device busy process because two forming tool heads act on the both sides of plate respectively, feeding by two forming tool heads cooperates pointwise to make plate that plastic deformation constantly take place, thereby do not need concavo-convex mould just can produce the various metal blank parts that contain projection and depression curved surface simultaneously, thereby the more traditional concavo-convex finishing die of this device have bigger processing flexibility;
(2) this device is in sheet forming process, and the motion by control industrial machine hand-motion forming head both can realize the shaping to the monoblock plate, can realize shaping or school shape to the local zonule of plate again;
(3) because this device does not need traditional male and female mold in sheet forming process, thereby avoided traditional moulds in process of production need spend the process that great amount of manpower and material resources repair a die repeatedly, thereby can realize lower processing cost and production time still less, be applicable to the shaping processing of parts in small batch such as having various complex-curved automobile panels, aerospace flight vehicle shell;
(4) this device utilizes existing ripe industrial machine hand, thereby simpler than other former structures, and establishment and maintenance cost are lower.
