Abstract
The utility model discloses a flip-over type rubber blanking die which relates to a stamping die. The flip-over type 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 male die is arranged on the lower die seat and fixedly connected to the lower die seat through a male die fixing plate; an unloading plate is arranged on the male die; an unloading screw is arranged on the unloading plate; an unloading spring is sleeved outside the unloading screw; an accommodating frame is arranged on the bottom surface of the upper die seat; a padding plate is arranged between the upper die seat and the accommodating frame; a through hole matched with the male die is formed on the bottom surface of the accommodating frame in a position corresponding to the male die; a rubber die cushion is arranged in the through hole; the lower surface of the rubber die cushion is flushed with that of the accommodating frame; and a groove is formed on the lower surface of the padding plate in a position corresponding to the rubber die cushion. The flip-over type rubber blanking die has a simple manufacture process, can keep a workpiece in a smooth state in the whole punching process, reduces sentus, avoids the phenomenon of turned edge, improves the product quality and is highly practical.
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, and described upper bolster bottom surface is provided with the appearance frame, is provided with backing plate between upper bolster and the appearance frame, hold the position corresponding, frame bottom surface and have the through hole that cooperates with punch with punch, be provided with the rubber die-cushion in the through hole, the lower surface of rubber die-cushion flushes with the lower surface that holds frame, and the position that the backing plate lower surface is corresponding with the rubber die-cushion has groove.
As preferably, described rubber die-cushion adopts polyurethane rubber to make.
As preferably, described upper bolster and die shoe adopt the Q235 steel plate 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, the groove on the backing plate can reduce rubber die-cushion surface local compression when backing plate can be avoided punching press, prolonged the service life of rubber die-cushion.Appearance frame of the present utility model can play the effect of guiding, therefore guide pillar, economical with materials can be set.Upper bolster and die shoe adopt the Q235 steel plate to make good combination property, long service life.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 comprises upper bolster 1 and die shoe 2, and in the present embodiment, as preferably, described upper bolster 1 and die shoe 2 adopt the Q235 steel plates to make.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, 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, 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, in the present embodiment, as preferably, described rubber die-cushion 10 adopts polyurethane rubbers to make.The lower surface of rubber die-cushion 10 flushes with the lower surface that holds frame 9, and backing plate 8 lower surfaces and rubber die-cushion 10 corresponding positions have groove 11.
