Description
Technical field
The utility model belongs to the metal manufacture field, is specifically related 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, particularly for compound die, high to the required precision of its punch-die, manufactures more difficultly, and cost is higher.And the workpiece of going out while 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
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, a kind of new type rubber compound flushing pressing mold is provided, its manufacture craft is simple, die cost is low, and make workpiece in punching course, be in all the time formation state, reduce burr, avoid edge-curl phenomenon, improve the quality of product.
The technical scheme that the utility model adopts 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, on punch-die, have the punching hole type hole of perforation, the position that the die shoe upper surface is corresponding with punch-die is provided with the appearance frame, described appearance frame is both ends open, the cylindrical shell of hollow, hold between frame outer wall and die shoe and be provided with the triangle ribs, in the cavity of appearance frame, be provided with the rubber die-cushion, described rubber die-cushion adopts polyurethane rubber to make, rubber die-cushion upper surface and appearance frame upper surface flush, between rubber die-cushion and die shoe, be provided with the rod that is shaped, hold the frame table face and be provided with the Corrosion Protection of Fiber Reinforced Plastics layer.
As preferably, in the punching hole type hole of punch-die, slidably connect push rod, 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, between punch-die and upper bolster, be provided with backing plate, 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.
As preferably, the bottom of triangle ribs and die shoe welding, sidewall with hold the frame welding.
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 held 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 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 material and being subject to the rubber pressure constantly increased 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 guide pillar can be set, saves material, easy to process.Hold between frame outer wall and die shoe and be provided with the triangle ribs, guarantee when metal works is carried out to bending, hold frame and die shoe and do not produce and relatively move, improved quality and the precision of product, very practical.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, die shoe; 2, hold frame; 3, guide plate; 4, holding pad; 5, push rod; 6, backing plate; 7, upper bolster; 8, make bar; 9, die shank; 10, fixed head; 11, binder spring; 12, punch-die; 13, rubber die-cushion; 14, shaping rod; 15, triangle ribs.
The specific embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
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, and 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, on punch-die 12, have the punching hole type hole of perforation, 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, hold between frame 2 outer walls and die shoe 1 and be provided with triangle ribs 15, guarantee when metal works is carried out to bending, hold frame 2 and do not produce and relatively move with die shoe 1, improved quality and the precision of product.In the present embodiment, as preferably, the bottom of triangle ribs 15 and die shoe 1 welding, sidewall with hold frame 2 welding.In the cavity of appearance frame 2, be provided with rubber die-cushion 13, described rubber die-cushion 13 adopts polyurethane rubber to make, rubber die-cushion 13 upper surfaces and appearance frame 2 upper surface flush, between rubber die-cushion 13 and die shoe 1, be provided with the rod 14 that is shaped, in the present embodiment, as preferably, described shaping rod 14 is two, near the inwall that holds frame 2, be symmetrical set, when the rod 14 that is shaped can increase punching press to the pressure of workpiece.Hold frame 2 surfaces and be provided with the Corrosion Protection of Fiber Reinforced Plastics layer, improved the antiseptic property that holds frame 2, extended service life of the present utility model.
