Detailed description of the invention
As shown in figs 2-4, a kind of composite punching die, comprises upper die and lower die.Wherein patrix is dynamic model, and counterdie is cover half.Patrix internal fixtion has upper punch 1, be provided with in counterdie can with the low punch 2 of upper punch 1 male-female engagement, upper punch 1 is fixing relative to patrix, and low punch 2 is also fixing relative to counterdie.Low punch 2 is included in the outer cutting blade of its top periphery, and the upper surface of low punch 2 is the contour shape of magnetic film finished product.When the punching press of annular magnetic film, upper punch 1 enters the sunk part of low punch 2 central authorities, goes out circular hole, is punched out the excircle of annulus by the outer cutting blade of low punch 2.
The outer wall of upper punch 1 is arranged with expeller 3, and this expeller 3 is slidably connected with upper punch 1 and can slides up and down at the outer wall of upper punch 1.The stroke chamber 4 slided up and down for expeller 3 is set out in patrix.The upper surface of expeller 3 is connected with the resetting-mechanism promoting expeller 3 and glide, and is provided with the thrust mechanism preventing expeller 3 from deviating from upper punch 1 in patrix.
As further preferred embodiment, the bottom surface of expeller 3 is and low punch 2 top surface shape, annular that size is identical.The shape of expeller 3 bottom surface is identical with the shape of magnetic film finished product, in punching press with when returning, is conducive to monoblock magnetic film finished product to be firmly pressed on low punch 2.
As further preferred embodiment, patrix comprises the upper bolster 5, upper padding plate 6, train wheel bridge 7 and the caster 8 that are connected and fixed successively from top to bottom.Upper punch 1 is rolled in the central authorities of caster 8 and train wheel bridge 7, and the upper end of upper punch 1 withstands on upper padding plate 6 lower surface, the lower surface of the slightly outstanding caster 8 in lower end.Resetting-mechanism is made up of three are centered around upper punch 1 periphery back-moving spring 9 in equilateral triangle, the upper surface of the lower end apical grafting expeller 3 of every root back-moving spring 9, upper end apical grafting upper padding plate 6.Back-moving spring 9 is contained in caster 8 through train wheel bridge 7 and bottom at above-below direction.Expeller 3 by under External Force Acting when stroke chamber 4 upward sliding, back-moving spring 9 forced compression, after external force is cancelled, expeller 3 depress is back to original position by back-moving spring 9.
As further preferred embodiment, stroke chamber 4 is positioned at caster 8 central authorities, and in the periphery of upper punch 1, the upper end in stroke chamber 4 is closed by train wheel bridge 7, prevent expeller 3 excessively on move the back-moving spring 9 caused and damage or accelerated ageing.
As further preferred embodiment, expeller 3 one-tenth T-shape, thrust mechanism comprises the thrust step 10 of clamping expeller 3 top T-shape ledge in caster 8, is mainly used for the location of expeller 3.When expeller 3 is connected to thrust step 10, expeller 3 lower surface protrudes from caster 8 and concordant upper punch 1 bottom surface.
As further preferred embodiment, counterdie comprises the die shoe 11 and lower bolster 12 that are connected and fixed successively from the bottom to top, die shoe 11 is provided with at the de-material spring 13 of above-below direction through lower bolster 12 in the surrounding of low punch 2, the top of de-material spring 13 is connected with outer de-plate 14, and outer de-plate 14 is set on low punch 2 periphery.Also have the guide pillar 15 of 4 orthogonal arrangements in the surrounding of low punch 2, every root guide pillar 15 can penetrate lower plate, outer de-plate 14, caster 8 and train wheel bridge 7 successively, plays guiding and location to upper die and lower die.
Implementation process of the present invention is such:
External automatic feeding drives the magnetic collagen material of sheet or band shape to enter the range of work, mould matched moulds is die-cut, upper punch 1 and low punch 2 male-female engagement go out the circular hole of product, the outer cutting blade of low punch 2 goes out the excircle of product, in this process, low punch 2 withstands expeller 3 by product and makes the relative upper punch 1 of expeller 3 moves, and back-moving spring 9 compresses; After punching out finished product, upper punch 1 fast return, expeller 3 is under the elastic recovery effect of back-moving spring 9, keep state finished product top being pressed in low punch 2 upper surface, until expeller 3 is taken away by the top of thrust step 10 clamping expeller 3, so, the finished product of annular namely can not play, also can not spin off completely from magnetic collagen material; Automatic feeding continues feeding in the horizontal direction, and annulus finished product leaves the range of work under the drive of magnetic collagen material, the die-cut next product of mould.Except collecting finished product, whole production process is all continuous print, substantially increases production efficiency.
The above is the preferred embodiment of the present invention, and it does not form limiting the scope of the invention.
