Abstract
The utility model relates to a sheet-forming die with a movable female die for a flexible bottom die, which comprises the movable female die, a male die, a lower die holder, ejector rods, a bolster, a pressure plate, air cylinders, an upper die holder, solid granules, a bottom die cavity and the like; the solid granule medium is arranged in the cavity of the movable female die upon the bolster; during forming, the movable female die, the bolster and a blank are formed into the closed bottom die cavity, and the solid granule medium is filled up in the bottom die cavity to serve as the flexible bottom die to provide back pressure. Since the utility model adopts the solid granule medium to provide back pressure, compared with a die adopting liquid medium to provide back pressure, forming is extremely easy, special equipment is not needed, the solid granules cannot leak, the environment cannot be polluted, and thereby safe and reliable production can be implemented. The distribution of the back pressure provided by the liquid medium is uniform, while the solid granule medium can provide ununiform back pressure, and consequently, the deformation degree of a sheet can be effectively increased, so that the thickness of the product can be uniform. The shape of the slide granule medium bottom die is determined by the shape of an ejector block, and can be adjusted according to specific requirements, so the product quality is higher.

1-die shoe, 2-push rod, 3-backing plate, 4-movable matrix, 5-holding pad, 6-cylinder, 7-upper bolster, 8-punch, 9-solid particle medium, 10-bed die die cavity, 11-blank.
The specific embodiment
Referring to Fig. 1, be depicted as a kind of sheet material molding die tool with flexible bed die movable matrix, comprise movable matrix 4, punch 8, die shoe 1, push rod 2, backing plate 3, holding pad 5, cylinder 6, upper bolster 7, solid particle bed die 9 etc.; One end of described punch 8 is mounted on the upper bolster 7, and the other end of punch 8 matches with the die cavity position of movable matrix 4; Described cylinder 6 is connected on the upper bolster 7, and the cylinder axis of cylinder 6 withstands in the groove of holding pad 5, or is connected in the groove of holding pad 5, and cylinder axis is corresponding during cylinder 6 work elongates or shortens, promote holding pad 5 and move up and down, near or away from upper bolster 7; Movable matrix 4 and backing plate 3 are arranged on the die shoe 1, and backing plate 3 is movably arranged in the die cavity of movable matrix 4, and backing plate 3 can be certain up and down in the die cavity of movable matrix 4, and backing plate 3 is corresponding with the position of punch 8.Die shoe 1 is passed in the upper end of push rod 2, withstands on the movable matrix 4, and push rod 2 externally acts on down motion up or down, drives die 4 and moves up or down synchronously; Backing plate 3 is provided with solid particle medium 9.When moulding, between movable matrix 4, backing plate 3 and blank 11, form the bed die die cavity 10 of a relative closure, solid particle medium 9 is filled in the bed die die cavity 10, as flexible bed die, produces back pressure when blank 11 moulding.
Mould of the present utility model adopts solid particle medium 9 that back pressure is provided, and provides the mould of back pressure to compare with liquid medium, is shaped and realizes that very easily do not need special installation, solid particle medium 9 can not leak, and is free from environmental pollution, can realize safe and reliable production.Can realize non-homogeneous back pressure, can effectively improve the sheet metal deformation degree, make product thickness even.
The shape of the flexible forming bed die that solid particle medium 9 forms is by the shape decision of backing plate 3, and is corresponding with the shape of backing plate 3 upper surfaces, can regulate according to specifically needing, and product quality is higher.
The course of work of the sheet material molding die of the flexible bed die movable matrix of the utility model band, mould of the present utility model has three course of action, and at first the cylinder axis with cylinder 6 outwards extends, and makes holding pad 5 moving away from upper bolster 7(one, cylinder 6 promotes holding pad 5); In the position of adjusting movable matrixes 4 by push rod 2, mainly be plate with blank 11() be placed on (two is moving, and push rod promotion movable matrix 4 moves) between holding pad 5 and the movable matrix 4; Cylinder axis with cylinder 6 shrinks (upwards shortening among the figure) then, drives holding pad 5 and moves to upper bolster 7, and push rod 2 protrudes upward synchronously simultaneously; Perhaps, move down, the lower end of punch 8 is contacted gradually with blank 11 by the motor drives punch 8 of lathe, and compressing blank 11 distortion (three is moving, and lathe drives punch 8 and moves down); When the upper end of holding pad 5 contact with upper bolster 7 make holding pad 5 stop to move up after, can adopt external force to make punch 8 continue to move down, with blank 11 by advancing in the solid particle medium 9, the back pressure moulding that provides by solid particle medium 9; Perhaps adopt external force that backing plate 3 is up moved, or die shoe 1 drives backing plate 3 and up moves, with blank 11 by advancing in the solid particle medium 9, the back pressure moulding that provides by solid particle medium 9.During moulding,, play poly-material effect earlier by 8 pre-profiling of rigidity punch.By flexible solid particles medium 9 final shaping units, guarantee to have very high formed precision again.
