Abstract
The utility model discloses an improvement structure of a stamping flanging die, which comprises a convex die and a concave die, the entrance edge of the concave die is provided with a guide plate, and the guide plate is chamfered toward the outside end of one side of the die cavity. The chamfer is an arc chamfer. The two sides of the convex die are provided with buffering pieces for buffering the impact of the two side plate when flanging. The stamping flanging die has the advantages by: effectively reducing the shearing force when a plate is pulled in the concave die due to the existence of the guide plate, reducing the probability that the plate is pulled to crack, and improving the yield rate and the flanging quality.
Description
Technical field:
The utility model relates to a kind of punching press flanging die.
Background technology:
The problem of wanting emphasis to note to the design of hardware stamping mould is how to prevent that the drawing crack phenomenon from appearring in handware in punching course, its die 02 cavity ingress edge of the hardware stamping flanging die (as shown in Figure 1) of prior art all is more sharp-pointed bent angle 03, when punching press, five metals sheet material at first passes through these sharp-pointed edges, under the pulling function of punch 01, five metals sheet material by drawing crack, causes poor product quality, the percent defective height through the part of sharp edges owing to be subjected to the effect of powerful shearing force.
Summary of the invention:
The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, the structure-improved of the cheap punching press flanging die of a kind of manufacturing cost and maintenance cost to be provided.
For achieving the above object, the technical scheme that the utility model provides is: the structure-improved of punching press flanging die, include punch and die, and be provided with the importing plate at the ingress edge of die, this imports the outer chamfer of plate towards die cavity one side.
Described chamfering is a circular arc chamfering.
The bolster that buffering both sides side plate impacts when the both sides of punch are provided with flange.
The advantage of this punching press flange die is: owing to import the existence of plate, effectively reduced the shearing force when sheet material is drawn in die, reduced sheet material by the probability of drawing crack, improved yield rate and flange quality.
Description of drawings:
Fig. 1 is the structural representation of prior art punching press flange die;
Fig. 2 is the structural representation of the die opening state of the utility model punching press flange die;
Fig. 3 is the structural representation of the matched moulds state of the utility model punching press flange die.
The specific embodiment:
Now elaborate the utility model:
The punching press flanging die of present embodiment includes punch 1 and die 2, is provided with at the ingress edge of die 2 and imports plate 3, and this imports the outer chamfer of plate 3 towards die cavity one side, and described chamfering 4 is a circular arc chamfering.During punching press, the circular arc chamfering quilt of sheet material through importing plate 3 soft transitions gradually drawn in, and greatly reduced the suffered shearing force of sheet material, reduces the generation of drawing crack phenomenon.Both sides side plate 6 impacts when alleviating flange, is provided with rubber bolster 5 in the both sides of punch 1.
The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
