Description
Technical field
The utility model belongs to metal manufacture field, is specifically related to the rubber combined stamping die of a kind of gapless.
Background technology
In punching production, when the thin material of stamping-out (expecting that metal material below thick 0.3mm and nonmetallic materials are as polyester film, woollen blanket, leather etc.), the blade clearance of these materials all, below 0.01mm, is commonly referred to gapless punching press.Gapless punching press requires working portion dimensional accuracy and the surface quality of stamping die high, and when making mould, difficulty is very large like this, and die cost is high.And can even there is edge-curl phenomenon with larger burr in the workpiece of going out while carrying out gapless punching press with existing stamping die, affect the quality of product.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provide a kind of gapless rubber combined stamping die, its manufacture craft is simple, die cost is low, and make workpiece in punching course all the time in formation state, reduce burr, avoid edge-curl phenomenon, improve the quality of product.
The technical scheme that the utility model adopts is: the rubber combined stamping die of a kind of gapless, comprise upper bolster, die shoe, die shank, guide pin bushing and guide pillar, punch-die is arranged at upper bolster below, on punch-die, be socketed with stripper, described stripper sidewall spacers is provided with some strip bulges, on stripper, be provided with unloading bolt, on unloading bolt, be socketed with rubber press; Die shoe upper surface is provided with appearance frame, described appearance frame is connected in die shoe upper surface by installing plate, appearance frame is the cylindrical shell of both ends open, hollow, in the cavity of appearance frame, be provided with rubber die-cushion, described rubber die-cushion adopts polyurethane rubber to make, the upper surface of rubber die-cushion and the upper surface flush of holding frame, hold frame upper surface and be provided with guide plate.
As preferably, in die shank, be provided with and make bar, make bar and can in die shank, slide, in the die hole of punch-die, be provided with push rod, push rod can slide in punch-die, makes bar corresponding with the position of push rod.
As preferably, between punch-die and upper bolster, be provided with backing plate, punch-die is fixedly connected on backing plate lower surface by fixed head, and punch-die is socketed with blank holder outward, and the lower surface of blank holder flushes with the lower surface of stripper.
As preferably, the position that die shoe upper surface is corresponding with rubber die-cushion has groove, and the width of groove is less than the width of rubber die-cushion.
The beneficial effects of the utility model are: the utility model adopts and holds frame and be arranged on the blanking die that the rubber die-cushion holding in frame has replaced conventional composite mould, need not carry out fine finishining to blanking die and punch-die, reduced die manufacturing cost, polyurethane rubber is a kind of elastomer, in punching course, hold in frame in closed state, thereby rubber die-cushion has liquid static pressure after stressed, the suffered unit pressure of rubber die-cushion all directions equates.When the descending drive die shank of press ram downward, punch-die, rubber die-cushion, stripper and blank holder compress the material being rushed, rubber die-cushion is subject to the pressure of punch-die, force and rushed material along punch-die and hold the stretching that bends of in-out-snap outline perimeter, and produce impression at punch-die and the cutting edge place that holds frame, descending with upper bolster, when being rushed rubber pressure that material is subject to constantly increasing and surpassing material shearing strength, material cracks at cutting edge place, and workpiece is separated with periphery material.The groove of die shoe upper surface can reduce rubber die-cushion surface local compression, extends the service life of rubber die-cushion.In whole punching course, workpiece, all the time in formation state, therefore can not produce burr and crimping, has improved the quality of product.Guide plate can play the effect of guiding when punching press, guarantees the precision of product.Stripper of the present utility model and blank holder be workpiece pressing simultaneously, avoids workpiece wrinkling.Hold frame and be connected in die shoe upper surface by installing plate, install and convenient disassembly.Stripper sidewall spacers is provided with some strip bulges, has improved the strength and stiffness of stripper, has improved punching precision, has good practicality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, upper bolster; 2, die shoe; 3, die shank; 4, punch-die; 5, fixed head; 6, blank holder; 7, stripper; 8, unloading bolt; 9, rubber press; 10, guide pin bushing; 11, guide pillar; 12, make bar; 13, push rod; 14, backing plate; 15, hold frame; 16, rubber die-cushion; 17, groove; 18, guide plate; 19, installing plate.
The specific embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As shown in Figure 1, the rubber combined stamping die of a kind of gapless, comprises upper bolster 1, die shoe 2, die shank 3, guide pin bushing 10 and guide pillar 11, and as preferably, upper bolster 1, die shoe 2 and die shank 3 adopt Q235 steel to make, and guide pin bushing 10 and guide pillar 11 adopt 20 steel to make.Punch-die 4 is arranged at upper bolster 1 below, is socketed with stripper 7 on punch-die 4, and described stripper 7 sidewall spacers are provided with some strip bulges (not shown in FIG.), have improved the strength and stiffness of stripper 7, have improved punching precision.On stripper 7, be provided with unloading bolt 8, on unloading bolt 8, be socketed with rubber press 9; Rubber press 9 can increase the pressure of 7 pairs of workpiece of stripper, and as preferably, described rubber press 9 adopts polyurethane rubbers to make.Die shoe 2 upper surfaces are provided with and hold frame 15, and described appearance frame 15 is connected in die shoe 2 upper surfaces by installing plate 19, install and convenient disassembly.Holding frame 15 is the cylindrical shell of both ends open, hollow, in the cavity of appearance frame 15, be provided with rubber die-cushion 16, described rubber die-cushion 16 adopts polyurethane rubber to make, the upper surface of rubber die-cushion 16 and the upper surface flush of holding frame 15, hold frame 15 upper surfaces and be provided with guide plate 18, guide plate 18 can play the effect of guiding when punching press, guarantees the precision of product.
