Abstract
The utility model discloses a novel rubber compound stamping die, and relates to a stamping die. The novel rubber compound stamping die comprises an upper die seat, a lower die seat and a die shank, wherein a punch-die is arranged on the lower surface of the upper die seat; a through punching-type hole is formed in the punch-die; an accommodating frame corresponding to the punch-die is arranged on the upper surface of the lower die seat; the accommodating frame is a hollow cylinder body, the two ends of which are opened; a rubber die cushion is arranged in a cavity of the accommodating frame; the rubber die cushion is made of polyurethane rubber; the upper surface of the rubber die cushion is flush with the upper surface of the accommodating frame; and a triangular reinforcing rib is formed on the side wall of the accommodating frame. The novel rubber compound stamping die is simple in manufacture process, and the cost of the die is low; in addition, the novel rubber compound stamping die can enable a workpiece to be in a flat state all the time during the stamping process, reduces burrs, avoids a turned edge phenomenon, improves the product quality, and achieves high practicability.
Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of new type rubber compound flushing pressing mold.
Background technology
In punching production, when the thin material of stamping-out (expecting metal material below 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 gapless punching press.Require working portion dimensional accuracy and the surface quality of stamping die high, difficulty is very large 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 more difficultly, and cost is higher.And the workpiece of going out when carrying out the gapless punching press with existing stamping die can edge-curl phenomenon even occur with larger burr, affects the quality of product.
Summary of the invention
Problem for above-mentioned prior art existence, the utility model provides a kind of new type rubber compound flushing pressing mold, its manufacture craft is simple, die cost is low, and make workpiece be in all the time formation state in punching course, reduce burr, avoid edge-curl phenomenon, improve the quality of product, very practical.
The technical solution of the utility model is: a kind of new type rubber compound flushing pressing mold, comprise upper bolster, die shoe and die shank, the upper bolster lower surface is provided with punch-die, have the punching hole type hole of perforation on punch-die, the position that the die shoe upper surface is corresponding with punch-die is provided with the appearance frame, described appearance frame is the cylindrical shell of both ends open, hollow, be provided with the rubber die-cushion in the cavity of appearance frame, described rubber die-cushion adopts polyurethane rubber to make, rubber die-cushion upper surface and appearance frame upper surface flush hold the frame sidewall and are provided with the triangle ribs.
As preferably, slidably connect push rod in the punching hole type hole of punch-die, the push rod upper end is connected with makes bar, makes bar and is positioned at upper bolster and die shank, and the upper surface of die shank is stretched out in the upper end of making bar, beats bar and upper bolster and die shank matched in clearance.
As preferably, be provided with backing plate between punch-die and upper bolster, punch-die is fixedly connected on the backing plate lower surface by fixed head, and punch-die is socketed with holding pad outward, and holding pad is connected with backing plate by the binder spring, holds the frame upper surface and is provided with guide plate.
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 that holds in frame has replaced the conventional composite mould, has reduced die manufacturing cost.Polyurethane rubber is a kind of elastomer, in punching course, hold in frame and be in closed state, thereby the rubber die-cushion has liquid static pressure after stressed, and namely 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 and blank holder compress the material that is rushed, the 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 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.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, very practical.
Description of drawings
Fig. 1 is 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 new type rubber compound flushing pressing mold, comprise upper bolster 7, die shoe 1 and die shank 9, in the present embodiment, as preferably, described upper bolster 7, die shoe 1 and die shank 9 all adopt the Q235 steel to make, good combination property, long service life.Upper bolster 7 lower surfaces are provided with punch-die 12, have the punching hole type hole of perforation on punch-die 12, the position that die shoe 1 upper surface is corresponding with punch-die 12 is provided with and holds frame 2, described appearance frame 2 is the cylindrical shell of both ends open, hollow, be provided with rubber die-cushion 13 in the cavity of appearance frame 2, described rubber die-cushion 13 adopts polyurethane rubber to make, rubber die-cushion 13 upper surfaces and appearance frame 2 upper surface flush, hold frame 2 sidewalls and be provided with triangle ribs 14, the bottom of the present embodiment intermediate cam shape ribs 14 and die shoe 1 welding, sidewall and 2 welding of appearance frame.
In the present embodiment, as preferably, slidably connect push rod 5 in the punching hole type hole of punch-die 12, push rod 5 upper ends are connected with makes bar 8, make bar 8 and be positioned at upper bolster 7 and die shank 9, the upper surface of die shank 9 is stretched out in the upper end of making bar 8, beats bar 8 and upper bolster 7 and die shank 9 matched in clearance.When making bar 8 and vertically be positioned at movably minimum point, the lower surface of punch-die 12 is stretched out in the lower surface of push rod 5.Push rod 5 and play the discharge that bar 8 facilitates waste material in the punching hole type hole.
