Description
One, technical field:
The utility model relates to the device that a kind of plate members curve generating is used, and is mainly used in the moulding of the adjustable segmented molds such as ship hull plate member with three-dimension curved surface and carries out the Plastic Forming processing of punching press, belongs to mechanical engineering field.
Two, background technology:
The manufacturing of curved surface plate material parts, its traditional curve generating method mainly is drawing.But drawing is mainly used in production in enormous quantities, and this manufacturing process is processed a kind of part often needs number cover monoblock type mould.Problems such as the precision of punch process part is good, quality is high, but has the die manufacturing cost height, and the production cycle is long.
Along with China's rapid economic development, shipbuilding industry is also developing rapidly.The batch of the ship hull plate identical components in the shipbuilding is few, complex-shaped, yardstick is big, and curvature is less, as makes all-in-one-piece large mold and process, and is then very expensive, almost is impossible.So for the ship hull plate member of simple curvature, generally be to use the method for three core rollers or hydraulic press to process at present; And, then be to use above-mentioned mechanical means to carry out horizontal curvature processing in advance for complex-curved ship hull plate member, on the basis of preliminarily forming, carry out buckling by the method for artificial use flame forming plate again.As everyone knows, the working condition of flame forming plate forming technology is poor, labour intensity big, require height, production efficiency to hang down inferior to workman's technical merit.
For this reason, people are in the discussion of carrying out multiple pressure head and multipoint mode sheet material forming.
Existing relevant representative art document has:
The pressure head of document 1 is a sphere curved surface, when the punching press moulding, contacts for " multiple spot " with sheet material, and the impression of sheet material is big after the punching press, and the sheet material of crushed element is easy to generate harmful buckling deformation by compression.For avoiding the generation of buckling deformation, around mould, measures such as flanging cylinder, blank holder or backing plate need be set in addition, but still can not solve the problem of the big and buckling deformation of impression well.The pressure head of document 2 is can be with the sphere curved surface of plate shape swing, but with sheet material also is to contact, and just contact area increases to some extent, is the fairness that keeps sheet material, need rubber blanket and cushion on the underneath of processed sheet material, can not solve the problem of the big and buckling deformation of impression equally well.The pressure head of document 3 is can be with the disc of plate shape swing, though the contact-making surface of pressure head and sheet material is big more than the former, but between each dish type pressure head, still have many sheet materials partly to expose, do not pushed down, so can cause the sheet material of crushed element by compression to produce harmful buckling deformation at this, in addition, because of the unstability of part in compression sheet material, order about a pair of pressure head generation swing of centering up and down, still make sheet material produce harmful buckling deformation.Find out that from the above-mentioned document that waits its pressure head is not outer to be disc or sphere curved surface.How preventing to produce buckling deformation and reduce impression in the plate stamping process, is a technical barrier in the processing of sheet material multiple pressure head and multipoint mode sheet material forming.
Three, summary of the invention:

Fig. 4 is the version schematic diagram of square ram.Square ram 1 is made up of square plate a and spheroid b two parts.The face of exerting pressure of side plate a is the plane, also can be made into the very large sphere curved surface of radius.When side's plate a face of exerting pressure was the plane, the marginal portion on the face of exerting pressure can be provided with tapering or radian c, and it is to make the face of exerting pressure of square ram 1 not form wedge angle that purpose is set, and avoided making sheet material to produce impression.Compare with other a multiple pressure sheet bending mode and the pressure head of multi-point formation apparatus for sheet material, because the contact area maximum of square ram 1 and sheet material 7, so have pressurized unstability that prevents sheet material 7 and the advantage that reduces impression.
But Fig. 5 is the connection diagram of square ram on mode transfer.For realizing the curve generating processing of sheet material 7, square ram 1 must be able to adapt to sheet material 7 bendings, and enough amplitudes of fluctuation should be arranged.For this reason, spheroid b on the square ram 1 partly be seated in end faces in the fixed frame 3 have the spill sphere supporter 2 on, use spring 8 that square ram 1 and fixed frame 3 are bound up flexibly forcefully, thereby square ram 1 just can obtain to adapt to the swing requirement of sheet material curve generating.
But Fig. 6 is the arrangement schematic diagram of upper and lower mode transfer.On, but the arrangement mode of mode transfer is down, by one group with rectangular mode compact arranged (M-1) but but * (N-1) mode transfer 4 formed of square ram 1 and by one group with the rectangular mode mode transfer 4 that compact arranged M * N square ram 1 is formed, but but go up the center of mode transfer 4 and the center of following mode transfer 4, projection on horizontal plane overlaps, but but the square ram 1 in mode transfer 4 and the mode transfer 4 down in the event, also the symmetric arrays of interlocking on vertical and horizontal, when sheet material 7 is exerted pressure, each square ram 1 can support mutually, can not produce wallowing motion because of sheet deformation causes square ram 1, but but any one square ram 1 of going up on the mode transfer 4 all can be supported by four the adjacent square rams on the following mode transfer 41, otherwise it is the same, but but any one square ram 1 on the following mode transfer 4 all can be supported by four the adjacent square rams on the last mode transfer 41, each square ram 1 can not produce wallowing motion because of the sheet material unstability, can force sheet material 7 at last on limiting, but carry out Plastic Forming in the gap that mode transfer 4 forms down, thereby can effectively prevent the generation of sheet material fold phenomenon.
Fig. 7 is to use the sheet material curve generating schematic representation of apparatus of square ram adjustable segmented mold.The sheet material curve generating device of square ram adjustable segmented mold comprises: the 1-square ram; The 2-supporter; The 3-fixed frame; But 4-mode transfer; The 6-forcing press.The load maintainer of present embodiment is a forcing press 6.One group of supporter 2 that has square ram 1 is contained in the fixed frame 3, but can form upper and lower mode transfer 4, but mode transfer 4 is installed on the base 6 (a) of forcing press 6 down, but going up mode transfer 4 is installed on the moved cross beam 6 (b) of forcing press 6, moved cross beam 6 (b) is connected with the oil cylinder 6 (d) of exerting pressure that is installed in 6 (c) that put the beams in place, and under the driving of oil cylinder 6 (d) that exert pressure, can move up and down but go up mode transfer 4, but, processed sheet material is carried out punch process with following mode transfer 4.
This shows, but because the square ram 1 that upper and lower mode transfer the being provided with face of exerting pressure of the present utility model is the plane, when plate stamping, 1 pair of sheet material of square ram is the face contact, significantly reduced the gap between the square ram 1, but and the square ram 1 of upper and lower mode transfer arrange for dislocation, but make the gap between the square ram 1 of upper and lower mode transfer no longer overlapping, therefore the generation of buckling deformation and impression in the punching course can be avoided effectively, crudy can be improved.
