Abstract

The utility model discloses a novel rubber stamping die, and relates to a stamping die. The novel rubber stamping die comprises an upper die seat, a lower die seat and a die shank, wherein a male die is arranged on the upper surface of the lower die seat; an accommodating frame is arranged on the lower surface of the upper 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; forming rods are arranged between the rubber die cushion and the upper die seat; two forming rods are provided, and are arranged close to the inner wall of the accommodating frame in a bilateral symmetry manner; the lower surface of the rubber die cushion is flush with the lower surface of the accommodating frame; and a guiding plate is arranged on the lower surface of the accommodating frame. The novel rubber stamping die achieves simple manufacture process, and the cost of the die is low; in addition, the novel rubber 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

The new type rubber stamping die
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of new type rubber stamping 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 when 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
Problem for above-mentioned prior art existence, the utility model provides a kind of new type rubber stamping die, 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, improved the quality of product, very practical.
The technical solution of the utility model is: a kind of new type rubber stamping die, comprise upper bolster, die shoe and die shank, the die shoe upper surface is provided with punch, described upper bolster lower surface is provided with the appearance frame, described appearance frame is the cylindrical shell of both ends open, hollow, is provided with the rubber die-cushion in the cavity of appearance frame, is provided with the rod that is shaped between rubber die-cushion and upper bolster, 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 the frame lower surface and be provided with guide plate.
As preferably, punch is fixedly connected on the die shoe upper surface by punch retainer, is socketed with stripper on punch, 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 that holds 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, and 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 that is 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 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.When backing plate can be avoided punching press to the damage of upper bolster.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 stamping die, comprise upper bolster 6, die shoe 1 and die shank 8, 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, and 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, holds frame 10 and adopts the Q235 steel to make.Hold in the cavity of frame 10 being provided with rubber die-cushion 5, be provided with the rod 9 that is shaped between rubber die-cushion 5 and upper bolster 6, described shapings rod 9 is two, be symmetrical set near the inwall that holds frame 10, 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 lower surfaces and be provided with guide plate 11, guide plate 11 can play the effect of guiding to workpiece when punch forming, guarantees the precision of product.
In the present embodiment, as preferably, punch 4 is fixedly connected on die shoe 1 upper surface by punch retainer 13, is socketed with stripper 12 on punch 4, 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 accuracy of workpiece, avoids workpiece wrinkling, and after punching press was completed, stripper 12 helped punch 4 dischargings under the effect of rubber blanket 3.
In the present embodiment, as preferably, punch 4 is up-small and down-big stairstepping, has improved the intensity of punch 4.Be provided with backing plate 7 between upper bolster 6 and appearance frame 10, backing plate 7 can prevent the direct impact to upper bolster 6, is shaped rod 9 between rubber die-cushion 5 and backing plate 7.Rubber die-cushion 5 adopts polyurethane rubber to make.
Above a kind of new type rubber stamping die provided by the utility model has been carried out detailed introduction, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.To be possible to change of the present utility model and improvement, and can not exceed design and the scope that accessory claim can be stipulated.
