Abstract
The utility model discloses a simple composite stamping die, relating to a stamping die. The simple composite stamping die comprises an upper die seat and a lower die seat. The upper die seat is provided with a die handle. A lower surface of the upper die seat is provided with convex and concave dies. An upper surface of the lower die seat is provided with a containing frame which is a hollow cylinder with openings at two ends. A cavity of the containing frame is provided with a rubber die cushion. A removable annular cushion block is arranged between the rubber die cushion and an inner wall of the containing frame. The rubber die cushion is made of polyurethane rubber, and the annular cushion block is natural rubber. The rubber die cushion and an upper surface of the annular cushion block are level with an upper surface of the containing frame. The upper surface of the containing frame is provided with a guide plate. A cushion plate is arranged between the containing frame and the lower die seat. A position of a cushion plate upper surface corresponding to the rubber die cushion is provided with a groove whose width is less than that of the rubber die cushion. According to the utility model, manufacture process is simple, die cost is low, a workpiece is always in a flat state in a stamping process, burr is reduced, a curling phenomenon is avoided, and the quality of a product is improved.
Description
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.
