Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Of the present invention a kind of high accuracy energy-conserving and environment-protective blanking die as shown in accompanying drawing 2-5, comprises the upper die component by several independent guide pillar about 19 relative motions and lower mold assemblies, unloading bolt 1 and stripper guide pillar 2; The punch 7 that described upper die component comprises cope match-plate pattern 3 connected successively from top to bottom, upper padding plate 4, upper mounted plate 5, stripper 6 and is fixed on upper padding plate 4; Multiple spring 8 is also provided with between described stripper 6 and upper mounted plate 5; Described upper padding plate 4 lower end is provided with four punch 7; Described each punch 7 is also provided with two and plays ejector pin 9; Described punch 7 is arranged in two row between two, and the front and back position of two row punch 7 is contrary; Described two row punch 7 are symmetrical about center of die line 20; The vertical height of described any row punch 7 arranges the height of a high punch 7 than another; The die 14 that described lower mold assemblies comprises lower bolster 10, mould pin 11, press plates 12, lower bolster 13 and is fixed on lower bolster 13; Structure and the punch 7 of described die 14 are suitable; Described lower bolster 10 is connected with press plates 12 by multiple mould pin 11; Described cope match-plate pattern 3, upper padding plate 4, to be connected by unloading bolt 1 between upper mounted plate 5 and stripper 6; Described upper padding plate 4 lower end is provided with stripper guide pillar 2; Described stripper guide pillar 2 is through upper mounted plate 5 and stripper 6, and die 14 is provided with guide pillar groove corresponding thereto; The side of fixed plate 5 is also provided with waste knife 15; Described mould pin 11 side is provided with slide plate 16; Described slide plate 16 one end is connected with lower bolster 13, and the other end is connected with waste material box 17; The quantity of described mould pin 11 is three; Several limited posts 19 are also provided with between described upper die component and lower mold assemblies.
Of the present invention a kind of high accuracy energy-conserving and environment-protective blanking die as shown in accompanying drawing 2-5, before actual processing, cope match-plate pattern is connected with punching mechanism, when starting to process tablet, coiled strip is delivered in the recessed film of blanking die by feed mechanism, then punching mechanism is started working, when punching mechanism down punching press time, drive cope match-plate pattern successively, upper mounted plate, upper padding plate and stripper bonded to each other toward pressing down, drive the punch of upper padding plate lower end and the die extruding bonded to each other of lower bolster upper end, so just allow four of upper padding plate lower end punch down aim at coiled strip and carry out punching press, coiled strip is made to process four tablets by the recessed membrane disposable of four on lower bolster, and be arranged in two row due to the protuberance of four in punch, have the interval of simultaneously each other, can ensure that coiled strip is when punching press like this, the pressurized at each position is balanced, avoid four tablets processed to produce the inconsistent problem of size, improve the precision of processing tablet.Then feed mechanism continues to transmit coiled strip, and then blanking die carries out cyclic process.
When after blanking die completion of processing, punching mechanism quits work, and then unloading bolt is unclamped, and then stripper just passes through spring automatic re-ascending to original position, thus makes blanking die get back to normal condition.
Further, be provided with waste knife in the side of upper mounted plate, for excising remaining waste material on coiled strip, also slide plate is provided with in cope match-plate pattern side, the slide plate other end is connected with waste material box, and after waste material being excised with waste knife, waste material can enter into waste material box automatically by slide plate; Between upper die component and lower mold assemblies, be also provided with limited post, for avoiding the position of upper die component and lower mold assemblies, both misplace direction in use.
High accuracy energy-conserving and environment-protective blanking die as above, a punching press of punching mechanism, just can stamp out four tablets, production efficiency improves four times, greatly improve for raw-material utilization rate, determine according to different product, raw material availability generally can improve between 16% ~ 30%.
A kind of high accuracy energy-conserving and environment-protective blanking die of the present invention program, it is easy to operate, simple and practical, the efficiency high speed stamping out tablet is fast, disposablely can process four tablets, and also by automatically sliding in waste material box by slide plate after waste knife excision waste material, this not only increases production efficiency, save production cost, also greatly improve raw-material utilization rate, extend the service life of blanking die, waste material is obtained deal carefully with, well meet the production and processing demand of medium-sized and small enterprises, various punching press industry can be widely used in, there is higher generalization and practical value.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
