Abstract

The utility model discloses a secondary deep drawing molding die which comprises an upper die base, an upper backing plate, an upper clamping plate, a first terrace die, a second terrace die, a guide column, a stripping plate, a lower clamping plate, a lower backing plate, a first concave die, a second concave die and a lower die base, the upper clamping plate and the upper backing plate are sequentially fixed on the upper die base, the upper ends of the first terrace die and the second terrace die are fixed on the upper clamping plate, the lower end of the guide column is fixed on the lower clamping plate, the stripping plate is connected on the guide column in a sliding mode, the lower clamping plate and the lower backing plate are sequentially fixed on the lower die base, the first concave die and the second concave die are fixed in the lower clamping plate and the lower backing plate, and the upper ends of the first concave die and the second concave die are opposite to the first terrace die and the second terrace die. According to the secondary deep drawing molding die, the first terrace die and the second terrace die are mutually matched with the first concave die and the second concave die so as to complete the secondary deep drawing, the structure is simple, the process is stable and reliable, and the rate of finished products is high.

Description

The secondary deep-drawing mould

Technical field

The utility model relates to a kind of cold punching die, particularly relates to a kind of secondary deep-drawing mould.

Background technology

Cold punching die is to be installed on the forcing press, and the plate in being placed on is at room temperature applied deformation force, makes it produce distortion, thereby obtains definite shape, the special specific purpose tool of the product parts of size and performance.Some metallic articles adopt once drawing easily the plate blank to be pulled open, so need adopt repeatedly the mode of pull and stretch to process because the degree of depth of its inner chamber is darker.

The utility model content

The purpose of the utility model is to provide a kind of simple in structure, secondary deep-drawing mould that yield rate is high.

For realizing above-mentioned purpose, the technical solution of the utility model is:

The utility model is a kind of secondary deep-drawing mould, and it comprises upper bolster, upper padding plate, train wheel bridge, first punch, second punch, guide pillar, stripper plate, lower plate, lower bolster, first die, second die, die shoe; Described train wheel bridge, upper padding plate are fixed on the upper bolster successively, and the upper end of first punch and second punch is fixed on the train wheel bridge; The lower end of described guide pillar is fixed on the lower plate, and stripper plate slips on guide pillar; Described lower plate, lower bolster are fixed on the die shoe successively, and first die and second die are fixed in lower plate and the lower bolster, and the upper end of first die and second die is relative with second punch with first punch.

After adopting such scheme, because the utility model mainly adopts first punch, second punch and first die, second die to cooperatively interact, accomplish secondary deep-drawing, structure is comparatively simple, and process stabilizing is reliable, and yield rate is high.

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

Description of drawings

Fig. 1 is the front view of the utility model.

The specific embodiment

As shown in Figure 1; The utility model is a kind of secondary deep-drawing mould, and it comprises upper bolster 1, upper padding plate 2, train wheel bridge 3, first punch 4, second punch 5, guide pillar 6, stripper plate 7, lower plate 8, lower bolster 9, first die 10, second die 11, die shoe 12.

Described train wheel bridge 3, upper padding plate 2 are fixed on the upper bolster 1 successively, and the upper end fixed interval of first punch 4 and second punch 5 is on train wheel bridge 3; The lower end of described guide pillar 6 is fixed on the lower plate 3, and stripper plate 7 slips on guide pillar 6.

Described lower plate 8, lower bolster 9 are fixed on the die shoe 12 successively, and first die 10 and second die, 11 fixed interval are in lower plate 8 and lower bolster 9, and the upper end of first die 10 and second die 11 is relative with second punch 5 with first punch 4.

The operation principle of the utility model:

When strip 100 is sent between stripper plate 7 and the lower plate 8, forcing press drives upper bolster 1 and moves downward, and accomplishes pull and stretch for the first time at first punch 4 with first die, 10 places, formation drawing part A; Strip 100 moves forward again, accomplishes pull and stretch for the second time at second punch 5 and second die, 11 places, forms drawing part B.

The emphasis of the utility model just is: adopt two cover cupping tools.

The above; Be merely the utility model preferred embodiment; So can not limit the scope that the utility model is implemented with this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.

Claims

1. secondary deep-drawing mould, it is characterized in that: it comprises upper bolster, upper padding plate, train wheel bridge, first punch, second punch, guide pillar, stripper plate, lower plate, lower bolster, first die, second die, die shoe; Described train wheel bridge, upper padding plate are fixed on the upper bolster successively, and the upper end of first punch and second punch is fixed on the train wheel bridge; The lower end of described guide pillar is fixed on the lower plate, and stripper plate slips on guide pillar; Described lower plate, lower bolster are fixed on the die shoe successively, and first die and second die are fixed in lower plate and the lower bolster, and the upper end of first die and second die is relative with second punch with first punch.
