Description

Simple and easy compound stamping die
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of simple and easy compound stamping die.
Background technology
In punching production, when the thin material of stamping-out (expecting metal material and nonmetallic materials such as polyester film, woollen blanket, leather etc. below the thick 0.3mm), the blade clearance of these materials all below 0.01mm, is commonly referred to the punching press of no gap.Require the working portion dimensional accuracy and the surface quality of stamping die high, difficulty is very big when making mould like this, and cost of manufacture is high, and is high to the required precision of its punch-die particularly for compound die, makes difficulty more, and cost is higher.And the workpiece of going out when not having the gap punching press with existing stamping die can have bigger burr, even edge-curl phenomenon occurs, influences the quality of product.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of simple and easy compound stamping die, and its manufacture craft is simple; Die cost is low, and makes workpiece in punching course, be in formation state all the time, reduces burr; Avoid edge-curl phenomenon, improve the quality of product.
The technical scheme of the utility model is: a kind of simple and easy compound stamping die, comprise upper bolster and die shoe, and upper bolster is provided with die shank; The upper bolster lower surface is provided with punch-die, and said die shoe upper surface is provided with the appearance frame, and the appearance frame is the cylindrical shell of both ends open, hollow; Be provided with the rubber die-cushion in the cavity of appearance frame, be provided with dismountable annular cushion block between rubber die-cushion and the appearance frame inwall, the rubber die-cushion adopts polyurethane rubber to process; The annular cushion block adopts natural rubber to process; The upper surface of rubber die-cushion and annular cushion block and the flush of holding frame hold the frame upper surface and are provided with guide plate, hold between frame and the die shoe being provided with backing plate; The position that the backing plate upper surface is corresponding with the rubber die-cushion has groove, and the width of groove is less than the width of rubber die-cushion.
As preferably, be provided with in the upper bolster and make bar, make bar and can in upper bolster and die shank, slide, be provided with push rod in the die hole of punch-die, push rod can slide in punch-die, and it is corresponding with the position of push rod to make bar.
As preferably, said upper bolster, die shoe and die shank adopt the Q235 steel to process, and upper bolster and die shank are one-body molded, are socketed with blank holder on the punch-die, and the lower surface of blank holder flushes with the lower surface of punch-die.
The beneficial effect of the utility model is: the utility model adopts and holds frame and be arranged on the blanking die that the rubber die-cushion that holds in the frame has replaced the conventional composite mould, has reduced die manufacturing cost.Polyurethane rubber is a kind of elastomer, in punching course, hold in the frame and be in closed state, thereby the rubber die-cushion has liquid static pressure property after stressed, and promptly the suffered unit pressure of rubber die-cushion all directions equates.Downward when the descending drive die shank of press ram, punch-die, rubber die-cushion and blank holder compress the material that is dashed, and the rubber die-cushion receives the pressure of punch-die; Force by towards material along punch-die with hold the stretching that bends of in-out-snap outline perimeter; And produce impression with the cutting edge place that holds frame at punch-die, descending with upper bolster, when the rubber pressure that is received continuous increase towards material surpasses the material shearing strength; Material cracks at the cutting edge place, and workpiece separates with periphery material.In whole punching course, workpiece is in formation state all the time, therefore can not produce burr and crimping, has improved the quality of product.When can avoiding punching press, backing plate, prolongs the service life of die shoe to the damage of die shoe.Groove on the backing plate can reduce rubber die-cushion surface local compression, prolongs the service life of rubber die-cushion.Guide plate can play the effect of guiding when punching press, therefore can guide pillar be set, and economical with materials is easy to process.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As a kind of embodiment of the utility model, as shown in Figure 1, a kind of simple and easy compound stamping die; Comprise upper bolster 1 and die shoe 2, upper bolster 1 is provided with die shank 3, in the present embodiment; As preferably; Said upper bolster 1, die shoe 2 and die shank 3 adopt the Q235 steel to process good combination property, long service life.Upper bolster 1 is one-body molded with die shank 3, and intensity is high.Upper bolster 1 lower surface is provided with punch-die 7, and said die shoe 2 upper surfaces are provided with and hold frame 8, and holding frame 8 is the cylindrical shell of both ends open, hollow; Be provided with rubber die-cushion 9 in the cavity of appearance frame 8, be provided with dismountable annular cushion block 13, the upper surface of rubber die-cushion 9 and annular cushion block 13 and the flush of holding frame 8 between rubber die-cushion 9 and appearance frame 8 inwalls; Said rubber die-cushion 9 adopts polyurethane rubber to process; Annular cushion block 13 adopts natural rubbers to process, in the present embodiment, and as preferably; Said annular cushion block 13 is two, is socketed on rubber die-cushion 9 outer surfaces from inside to outside successively.In the actual production, can make the utility model be applicable to the workpiece processing of different size through the annular cushion block 13 of changing different size or the quantity of adjusting annular cushion block 13.
Hold frame 8 upper surfaces and be provided with guide plate 11, guide plate 11 can be when punch forming plays the effect of guiding to workpiece, guarantees the precision of product.Hold between frame 8 and the die shoe 2 being provided with backing plate 10, backing plate 10 upper surfaces have groove 12 with rubber die-cushion 9 corresponding positions, and the width of groove 12 is less than the width of rubber die-cushion 9.
