Abstract
The utility model discloses an inverted rubber blanking die and relates to a stamping die. The inverted rubber blanking die comprises an upper die seat and a lower die seat, wherein a die handle is arranged on the upper die seat; a convex die is arranged on the lower die seat and is fixedly connected to the lower die seat through a convex die fixing plate; a discharging plate is arranged on the convex die; a discharging screw is arranged on the discharging plate; a discharging spring is sleeved outside the discharging screw; a containing frame is arranged on the bottom surface of the upper die seat; a through hole matched with the convex die is arranged on the bottom surface of the containing frame corresponding to the convex die; a rubber die cushion is arranged in the through hole; the lower bottom surface of the rubber die cushion is parallel and aligned with the lower bottom surface of the containing frame which is made of Q235 steel; and a blank holder is sleeved outside the convex die. The inverted rubber blanking die has the simple manufacturing process, can lead workpieces in the smooth state in the stamping process, reduces the burrs, avoids the hemming, improves the quality of the products and has strong practicability.
Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of flip-over type rubber blanking die.
Background technology
In punching production, when the thin material of stamping-out (expecting metal material below the thick 0.3mm and nonmetallic materials such as polyester film, woollen blanket, leather etc.), 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 height of stamping die, difficulty is very big when making mould like this, 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.
The utility model content
At the problem that above-mentioned prior art exists, the utility model provides a kind of flip-over type rubber blanking die, and its manufacture craft is simple, and make workpiece in punching course, be in formation state all the time, reduce burr, avoid edge-curl phenomenon, improve the quality of product, very practical.
The technical solution of the utility model is: a kind of flip-over type rubber blanking die, comprise upper bolster and die shoe, upper bolster is provided with die shank, die shoe is provided with punch, punch is fixedly connected on the die shoe by punch retainer, punch is provided with stripper, stripper is provided with the discharging screw, the discharging screw is with the discharging spring outward, described upper bolster bottom surface is provided with the appearance frame, holds the position corresponding with punch, frame bottom surface and has the through hole that cooperates with punch, is provided with the rubber die-cushion in the through hole, the bottom surface of rubber die-cushion flushes with the bottom surface that holds frame, holds frame and adopts the Q235 steel to make; Punch is socketed with blank holder outward.
As preferably, be provided with backing plate between upper bolster and the appearance frame.
As preferably, described rubber die-cushion adopts polyurethane rubber to make.
The beneficial effects of the utility model are: the utility model adopts and holds frame and be arranged on the die that the rubber die-cushion that holds in the frame has replaced traditional stamping die, polyurethane rubber is a kind of elastomer, in the blanking process, hold in the frame and be in closed state, thereby the rubber die-cushion has liquid static pressure after stressed, and promptly the suffered unit pressure of rubber die-cushion all directions equates.When the descending drive die shank of press ram downward, punch, rubber die-cushion and stripper compress the material that is dashed, the rubber die-cushion is subjected to the pressure of punch, force by towards material along punch with hold the stretching that bends of in-out-snap outline perimeter, and produce impression at punch and the cutting edge place that holds frame, descending with upper bolster, when being surpassed the material shearing strength by the rubber pressure that is subjected to towards material constantly increasing, material cracks at the cutting edge place, and workpiece separates with periphery material.In whole blanking process, workpiece is in formation state all the time, therefore can not produce burr and crimping, has improved the quality of product.To the damage of upper bolster, appearance frame of the present utility model can play the effect of guiding when backing plate can be avoided punching press, therefore guide pillar, economical with materials can be set.Blank holder has increased the pressure to strip, and anti-stopping materials strip is wrinkling, very practical.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As a kind of embodiment of the present utility model, as shown in Figure 1, a kind of flip-over type rubber blanking die, comprise upper bolster 1 and die shoe 2, upper bolster 1 is provided with die shank 3, die shoe 2 is provided with punch 4, punch 4 is fixedly connected on the die shoe 2 by punch retainer 5, punch 4 is provided with stripper 6, and stripper 6 is provided with discharging screw 7, the discharging screw 7 outer discharging springs that are with, described upper bolster 1 bottom surface is provided with and holds frame 9, in the present embodiment, as preferably, be provided with backing plate 8 between upper bolster 1 and the appearance frame 9.Hold frame 9 bottom surfaces and punch 4 corresponding positions and have the through hole that cooperates with punch 4, be provided with rubber die-cushion 10 in the through hole, the bottom surface of rubber die-cushion 10 flushes with the bottom surface of appearance frame 9, and appearance frame 9 employing Q235 steel are made; In the present embodiment, as preferably, described rubber die-cushion 10 adopts polyurethane rubbers to make.The punch 4 outer blank holders 11 that are socketed with.
