  • Shaping Metal By Deep-Drawing, Or The Like (AREA)

Abstract

A drawing die set for punching metallic sheet workpiece is composed of female die, male die and side-pressing ring, and features that on the pressing surface of side-pressing ring, there are straight or annular draw tendons and at the corner of the said pressing surface, oblique draw tendons for controlling the extension of metallic sheet in its shaping procedure. Its advantages are high percentage of finished products and high quality of products.

Description

Drawing die for forming metallic sheet by punching
Technical field: the architecture advances that the present invention relates to the drawing die that the moulding of a kind of sheet metal part punching uses.
Background technology: drawing die is made up of die, punch, blank holder three parts usually in the prior art, bead is set usually to prevent the wrinkling or drawing crack of workpiece on the binder surface of blank holder, forming defect appears, but because the setting of the bead of existing drawing die is generally straight line or loop wire, for deep-drawing spare, overcome the wrinkling or drawing crack poor effect in its bight, forming defect often occurs, and causes decrease in yield.
Summary of the invention: technical problem to be solved by this invention is to overcome deficiency of the prior art, and a kind of metal sheet punch forming drawing die that can effectively overcome forming defects such as deep-drawing spare bight is wrinkling, drawing crack, improve stamped workpieces yield rate and end product quality is provided.
Solving the problems of the technologies described above the technical scheme that is adopted is: the present invention includes die, punch, blank holder, the binder surface of blank holder is provided with straight shape bead or annular bead or straight shape bead and annular bead, it is characterized in that being provided with oblique bead in the bight of the binder surface of blank holder.
Among the present invention owing to increased oblique bead in drawn component moulding bight, metal-sheet parts material mobile in forming process had the better controlled effect, particularly can effectively overcome the wrinkling defective of drawn component in the punch forming of deep-drawing spare in the drawn component punch forming, prevent that the bight is wrinkling and the drawing crack effect is splendid, thereby the raising yield rate improves end product quality.
Description of drawings:
Fig. 1 is the structure front elevational schematic of drawing die in the prior art.
Fig. 2 is the perspective view of the embodiment of the invention one.
Fig. 3 is the perspective view of the embodiment of the invention two.
Fig. 4 is for being that the prior art bead of example is provided with schematic diagram with the punching press automobile top-cap.
Fig. 5 is for being that the bead of the present invention of example is provided with schematic diagram with the punching press automobile top-cap.
The specific embodiment: shown in Fig. 2,3, the present invention includes die 1, punch 2, blank holder 3, the binder surface 31 of blank holder 3 is provided with straight shape bead 32 or annular bead 33 or straight shape bead 32 and annular bead 33, it is characterized in that being provided with oblique bead 34 in the bight of the binder surface 31 of blank holder 3.
As a further improvement on the present invention, described oblique bead 34 is connected (shown in Fig. 2,5) with straight shape bead 32 smooth transition; Described oblique bead 34 also can be provided with separately, is not connected with straight shape bead 32, as shown in Figure 3, has one section oblique bead 34 not to be connected with straight shape bead 32 among this figure.
Fig. 1 has provided the front elevational schematic of the drawing die structure of prior art, among this figure on the binder surface of blank holder bead be straight shape bead.With the punching press automobile top-cap is example, and Fig. 4 has provided the situation that is provided with of bead in the prior art, and Fig. 5 has provided bead of the present invention example is set.
