Abstract
The utility model discloses a stretching die structure. The stretching die structure comprises a convex die and a concave die and is characterized in that the convex die is arranged in the concave die, a knockout plate is arranged inside the concave die, the knockout plate and the concave die are fixed together through an unloading screw, the unloading screw is provided with a spring, a pressing plate is installed on each of two sides of the convex die, an ejector rod is arranged on the left side of the convex die, and the top end of the ejector rod is connected with the bottom of each pressing plate. The stretching die structure has the beneficial effects that the structure is simple, the stretching quality of a workpiece is high, and the precision is high.
Description
Technical field
The utility model relates to a kind of stretching die structure, and it mainly is applicable to box-like workpiece manufacturing field.
Background technology
Design to the box part drawing die, has only the rational design parameter of employing, consider simultaneously the influence of the various factors in the drawing process again, could improve the pull and stretch quality of workpiece, during the mould design, to guarantee simultaneously that drawing part reaches this two kinds of required precisions, obviously be difficult for, therefore, in dimensional accuracy and perpendicularity between the two, perpendicularity requires to play crucial leading role, as long as manage to guarantee the perpendicularity requirement of box-like drawing part sidewall, dimensional accuracy just reaches easily, and therefore the improvement of respective inner structure should be arranged existing mould structure.
Summary of the invention
At the technological deficiency that above-mentioned the said goods exists, the utility model provides a kind of simple in structure, workpiece stretching quality height, a kind of stretched film structure that precision is high.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of stretched film structure comprises: punch and die is characterized in that: described punch is as in the die, and the inside of described die is provided with knockout plate, and described knockout plate and die are fixed by the discharging screw, is provided with spring at described discharging screw.
Described punch both sides are equipped with the flanging plate, are provided with push rod in the left side of described punch.
The top of described push rod is connected with the bottom of described flanging plate.
The beneficial effects of the utility model are: simple in structure, workpiece stretching quality height, precision height.
Description of drawings
Fig. 1 is the utility model structural representation.
