Abstract
The utility model discloses a novel thin material cutting die. The novel thin material cutting die comprises an upper die seat, a lower die seat and a die handle, wherein a convex die is arranged at the upper surface of the lower die seat, a groove is formed in the corresponding position on the upper surface of the lower die seat, a wearing plate is arranged in the groove, a containing frame is arranged at the lower surface of the upper die seat and is a hollow cylinder in which two ends are opened, a rubber die cushion is arranged in the cavity of the containing frame, and two forming rods are arranged between the rubber die cushion and the upper die seat and are transversely and symmetrically arranged close to the inner wall of the containing frame; the lower surface of the rubber die cushion is level with the lower surface of the containing frame; triangular reinforcing ribs are arranged at the outer surface of the side wall of the containing frame. The novel thin material cutting die has the advantages that the manufacture process is simple, and the die cost is low; a workpiece is throughout in a flat state in a punching process, burrs are reduced, a crimping phenomenon is avoided, and the product quality is improved.
Description
Technical field
The utility model belongs to the metal manufacture field, is specifically related to a kind of Novel thin material blanking die.
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 the cost of mfg. moulding die is high, and the workpiece of going out while carrying out the gapless punching press with existing stamping die can be with larger burr, edge-curl phenomenon even occurs, affect 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 Novel thin material blanking die 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, improved the quality of product.
The technical scheme that the utility model adopts is: a kind of Novel thin material blanking die, comprise upper bolster, die shoe and die shank, the die shoe upper surface is provided with punch, the position that the die shoe upper surface is corresponding with punch has groove, in this groove, be provided with wear strip, described upper bolster lower surface is provided with the appearance frame, described appearance frame is the cylindrical shell of both ends open, hollow, in the cavity of appearance frame, be provided with the rubber die-cushion, between rubber die-cushion and upper bolster, be provided with the rod that is shaped, described shaping rod is two, is symmetrical set near the inwall that holds frame; Rubber die-cushion lower surface flushes with the lower surface that holds frame; Hold frame sidewall outer surface and be provided with the triangle ribs.
As preferably, punch is fixedly connected on the die shoe upper surface by punch retainer, on punch, is socketed with stripper, and stripper is flexibly connected by unloading bolt and die shoe, and unloading bolt is socketed with rubber blanket outward.
As preferably, upper bolster and die shoe adopt the Q235 steel to make, and punch is up-small and down-big stairstepping, and upper bolster is provided with backing plate with holding between frame, and rubber die-cushion employing polyurethane rubber is made.
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 held in frame has replaced traditional stamping die, 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, namely 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 rushed, the rubber die-cushion is subject to the pressure of punch, force and rushed material along punch and 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 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.When backing plate can be avoided punching press to the damage of upper bolster.The triangle ribs has improved the intensity of holding frame, has avoided the horizontal play of appearance frame.The position that the die shoe upper surface is corresponding with punch has groove, is provided with wear strip in this groove, and when wear strip can effectively prevent punching press, punch caused damage to die shoe, had extended the service life of die shoe, had saved cost, very practical.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, die shoe; 2, unloading bolt; 3, rubber blanket; 4, punch; 5, rubber die-cushion; 6, upper bolster; 7, backing plate; 8, die shank; 9, shaping rod; 10, hold frame; 11, triangle ribs; 12, stripper; 13, punch retainer; 14, wear strip.
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 Novel thin material blanking die, comprise upper bolster 6, die shoe 1 and die shank 8, and in the present embodiment, as preferably, described upper bolster 6 and die shoe 1 adopt the Q235 steel to make, good combination property, long service life.Die shoe 1 upper surface is provided with punch 4, the position that die shoe 1 upper surface is corresponding with punch 4 has groove, in this groove, is provided with wear strip 14, and when wear strip 14 can effectively prevent punching press, 4 pairs of die shoes 1 of punch caused damage, extend the service life of die shoe 1, saved cost.Described upper bolster 6 lower surfaces are provided with and hold frame 10, and described appearance frame 10 is the cylindrical shell of both ends open, hollow, in the present embodiment, hold frame 10 and adopt the Q235 steel to make.Hold in the cavity of frame 10 and be provided with rubber die-cushion 5, between rubber die-cushion 5 and upper bolster 6, be provided with the rod 9 that is shaped, described shapings rod 9 is two, near the inwall that holds frame 10, be symmetrical set, when shaping excellent 9 can increase punching press to the pressure of workpiece.Rubber die-cushion 5 lower surfaces flush with the lower surface that holds frame 10; Hold frame 10 sidewall outer surfaces and be provided with triangle ribs 11, triangle ribs 11 has improved the intensity of holding frame 10, has avoided the horizontal play of appearance frame 10.
In the present embodiment, as preferably, punch 4 is fixedly connected on die shoe 1 upper surface by punch retainer 13, on punch 4, is socketed with stripper 12, and stripper 12 is flexibly connected by unloading bolt 2 and die shoe 1, the outer rubber blanket 3 that is socketed with of unloading bolt 2.When rubber blanket 3 does not compress, the upper surface flush of the upper surface of stripper 12 and punch 4 or exceed punch 4 upper surface 2-3mm.When punch forming, stripper 12 can workpiece pressing, guarantees the positioning precision of workpiece, avoids workpiece wrinkling, and after punching press completed, stripper 12 helped punch 4 dischargings under the effect of rubber blanket 3.
