Abstract

The invention discloses a bending mechanism which is applied to a stamping die. The stamping die comprises a clamping plate, a stripper plate, a lower die plate and a lower cushion plate; the bending mechanism comprises a punch, a forming insert core, a baffle insert core, and a plurality of elastic components; one end of the punch is arranged in the clamping plate; gaps are reserved between two sides of the punch and the clamping plate and between two sides of the punch and the stripper plate; one end of the forming insert core is matched with the lower die plate; the upper surface of the forming insert core is contacted with a product; one end of the baffle insert core is arranged in the lower cushion plate, and the other end of the baffle insert core has an inclined surface; and the elastic components are arranged in the clamping plate and are pressed against the punch. Compared with the prior art, the bending mechanism has the advantages that the bending mechanism comprises the elastic components, and the baffle insert core has the inclined surface, the vertical movement of the punch is converted into the inclined movement, and the product is gradually thrust on one side in place under the action of side thrust, so that the movement track of the punch on the surface of the product can be avoided, and yield is improved.

Description

Bending mechanism

[technical field]

The present invention relates to a kind of bending mechanism, be specifically related to a kind of bending mechanism that is applied in the diel.

[background technology]

Along with the continuous development in market, for electronic products such as notebook computer, PDA (palm PC), mobile phones, the consumer more and more favors the product of aluminium stretching shell; Because the accuracy of this series products; The appearance requirement of product is very high, therefore, and when this series products of moulding; The motion vestige that in the bending process, forms during mould molding just becomes a major issue that needs to be resolved hurrily in the diel.

In existing Production of Stamping Die, see also Fig. 1, shown in Figure 2, it illustrates existing bending mechanism mould respectively and begins closure state sketch map and the complete closure state sketch map of mould.Product 10 is located at the lower bolster 70 of mould and is gone on the son 2 with moulding; In the bending process, the part of the upper die of diel is along with punch press moves to the direction near lower bolster 70, and at first stripper plate 60 is pressed on the part that does not need moulding on the product 10 on the lower bolster 70; Drift 1 stretches out the patrix bottom surface gradually then; And to the direction motion near lower bolster 70, the place that product 10 is needed moulding is to direction of arrow bending shown in Figure 1, until accomplishing whole bending process.

Yet; When use had bending mechanism bending product 10 now, because the gap of having only product 10 thickness between the son 2 is gone in drift 1 and moulding, drift 1 was close-fittings with product 10; No empty avoiding gap; Drift 10 moves both vertically on compacted product 10 surfaces, thereby stays the motion vestige on product 10 surfaces, influences the outward appearance of product 10.

In view of this; In fact be necessary to develop a kind of bending mechanism, the mode that moves both vertically of drift when this bending mechanism can fundamentally change moulding, and with heeling condition with product gradually thruster put in place; Thereby avoided the motion vestige of product surface drift, improved the product yield.

[summary of the invention]

Therefore; The purpose of this invention is to provide a kind of bending mechanism, the mode that moves both vertically of drift when this bending mechanism can fundamentally change moulding, and with heeling condition with product gradually thruster put in place; Thereby avoided the motion vestige of product surface drift, improved the product yield.

For achieving the above object, bending mechanism of the present invention, it is applied in the diel, and this diel comprises: clamping plate, stripper plate, lower bolster, lower bolster, this bending mechanism comprises:

Drift, the one of which end is located in the above-mentioned clamping plate, and motion under these clamping plate drive, and is respectively equipped with the gap between this drift and above-mentioned clamping plate, the above-mentioned stripper plate;

Son is gone in moulding, and the one of which end matches with above-mentioned lower bolster, and this moulding is gone into sub-upper surface and contacted with product;

Backgauge is gone into son, and the one of which end is located in the above-mentioned lower bolster, and the other end is provided with the inclined-plane;

The plurality of elastic element, it is located at respectively in the above-mentioned clamping plate, and inconsistent with above-mentioned drift.

Preferable, above-mentioned flexible member is a spring.

Preferable, the number of above-mentioned flexible member is three.

Compared to prior art, bending mechanism of the present invention has increased flexible member and inclined-plane; Moving both vertically of drift become banking motion; Under the side-thrust effect, gradually the product thruster is put in place, thereby the motion vestige of having avoided the product surface drift to produce improves the product yield.

[specific embodiment]

Below in conjunction with accompanying drawing and the specific embodiment bending mechanism of the present invention is done and to be further described:

See also shown in Figure 3, bending mechanism of the present invention, it is applied in the diel, this diel comprises: clamping plate 500, stripper plate 600, lower bolster 700, lower bolster 800, this bending mechanism comprises:

Drift 100, one of which end are located in the above-mentioned clamping plate 500, and can under these clamping plate 500 drive, move, and are respectively equipped with the gap between this drift 100 and above-mentioned clamping plate 500, the above-mentioned stripper plate 600;

Son 200 is gone in moulding, and the one of which end matches with above-mentioned lower bolster 700, and this moulding is gone into sub 200 upper surfaces and contacted with product 10;

Backgauge is gone into son 300, and the one of which end is located in the above-mentioned lower bolster 800, and the other end is provided with inclined-plane 310;

Three flexible members 400; It is located at respectively in the above-mentioned clamping plate 500, and inconsistent with above-mentioned drift 100, when the mould die opening state; Under the effect of flexible member 400; Become heeling condition by plumbness between drift 100 and the clamping plate 500, in the present embodiment, this flexible member 400 is respectively spring.

See also Fig. 4, shown in Figure 5, after mould closes, stripper plate 600 touches product 10 at first; And the part that does not need moulding on the product 10 is pressed on the lower bolster 700, drift 100 stretches out the patrix bottom surface gradually, and the inclined-plane 310 of going into son 300 with backgauge contacts; And, changing the direction of motion gradually because of receiving the effect on this inclined-plane 310, drift 100 is after touching product 10; Under the effect of above-mentioned inclined-plane 310 side-thrusts, the part that product 10 is needed moulding along the direction of motion gradually thruster put in place, when mould is closed fully; Drift 100 moves to plumbness, and at this moment, product 10 needs the part of moulding to be put in place by thruster fully.

During with this kind mechanism shaped article 10; Product 10 is under free state, to go into son 200 to moulding gradually to promote, and drift 100 can not extruded vestige with product 10, when son 200 is gone in drift 100 and moulding with the complete jam-packed of product 10; Mould is closed fully; Drift 100 motions finish, and can on product 10, not move, and therefore can on product 10, not leave a trace.

Compared to prior art; Bending mechanism of the present invention; Increased flexible member 400 and inclined-plane 310, moving both vertically of drift 100 become banking motion, under the side-thrust effect, gradually product 10 thrusters have been put in place; Thereby the motion vestige of having avoided product 10 surperficial drifts 100 to produce has improved the product yield.
