Abstract

The invention discloses an outward flanging die, which comprises a lower die holder, an upper die holder, a wedge slider, a movable block, a guide column and a guide sleeve. The guide column and the guide sleeve are in slide fit with each other and are mounted in the upper die holder and the lower die holder, a movable block slide groove is fixedly connected onto the lower die holder, the movable block is placed in the movable block slide groove, a flanging pressing plate is arranged on the movable block, the upper portion of the flanging pressing plate corresponds to the lower portion of a flanging female die fixedly connected onto the upper die holder, a flanging male die is fixed onto a male die fixing plate, the flanging male die and the male die fixing plate are placed on the flanging pressing plate together, and the male die fixing plate and the movable block slide groove contact with each other via inclined surfaces to form a sliding friction pair and accordingly slide vertically along the inclined surfaces. The outward flanging die is relatively simple in structure, and can process a component required to be outwards flanged on an automatic production line, a production mode on a manual production line is changed fundamentally, working procedures are reduced, and cost is lowered.

Description

A kind of mould of outward flanging

Technical field

The present invention relates to the automobile component diel, particularly relate to a kind of mould that adopts wedge structure the automobile punch components to be carried out flange.

Background technology

For the flanging moulding of automobile punch components, be mostly to adopt the change pressing direction to change flanging the mode of in-flanges into during the mould design, thereby avoid mould structure complicated at present.But, so can increase the single raise mould, and can only on manual line, produce by the production line restriction, be difficult on the automatic production line and produce.

Summary of the invention

The mould that the purpose of this invention is to provide a kind of outward flanging, it can be processed the parts that need outward flanging on automatic production line, reduces operation, reduces cost.

The mould of a kind of outward flanging of the present invention comprises die shoe, upper bolster, wedge slide block, movable block, also comprises being installed in the guide pillars and bushes that is slidingly matched in upper bolster, the die shoe, it is characterized in that:

One movable block chute is fixedly connected on the said die shoe, and said movable block is placed in this movable block chute; Fit in the inclined-plane of the inclined-plane on movable block top and wedge slide block bottom, the movable block bottom is connected with an end of second retracting spring through the 3rd spring dead plate, an end wall of the other end of second retracting spring and movable block chute near;

One flange holding pad be located at said movable block above, the top of this flange holding pad is corresponding with the bottom of flange die on being fixedly connected on upper bolster;

One flanging die is fixed on the punch retainer, and together is placed in the flange holding pad; Punch retainer is connected with an end of first retracting spring through first spring dead plate, and the other end of first retracting spring is connected with the movable block chute through second spring dead plate; Punch retainer contacts through the inclined-plane with the movable block chute and produces sliding friction pair, thereby slides up and down along the inclined-plane.

The mould of described a kind of outward flanging, another end wall of its said movable block chute is provided with the backhaul limited block, and this backhaul limited block is corresponding with the end of movable block/contact.

The mould of described outward flanging is under the guiding of guide pillar, guide pin bushing; Move downward by upper bolster driving flange die (eccentric swage) and wedge slide block; When the flange die with after the flange holding pad contacts, the flange die is pushed down shaping blank with the flange holding pad, simultaneously; The wedge slide block continues to move downward and orders about it after movable block contacts and move backward, accomplishes flange laterally thereby drive flanging die along certain angle.Patrix backhaul after accomplishing flange, first retracting spring provides backhaul power, reaching the purpose of backhaul, thereby accomplishes whole outward flanging process.First retracting spring drives the flanging die backhaul, prevents to get stuck.

The present invention compares with prior art and has the following advantages: its structure is simple relatively, can on automatic production line, process the parts that need outward flanging, has fundamentally changed the mode of on manual line, producing, and has reduced operation, has reduced cost.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is further described.

Mould referring to Fig. 1, Fig. 2, Fig. 3 and a kind of outward flanging of the present invention shown in Figure 4; Comprise die shoe 14, upper bolster 15, wedge slide block 9, movable block 10; Also comprise being installed in guide pillar 16 and the guide pin bushing 17 that is slidingly matched in upper bolster, the die shoe, its design feature is:

One movable block chute 13 is fixedly connected on the said die shoe 14, and movable block 10 is placed in this movable block chute; Fit in the inclined-plane of the inclined-plane on movable block top and wedge slide block 9 bottoms, the movable block bottom is connected with an end of second retracting spring 12 through the 3rd spring dead plate 11, an end wall of the other end of second retracting spring and movable block chute 13 near;

One flange holding pad 2 be located at movable block 10 above, the top of this flange holding pad is corresponding with the bottom of flange die 1 on being fixedly connected on upper bolster;

One flanging die 3 is fixed on the punch retainer 5, and together is placed in the flange holding pad 2; Punch retainer 5 is connected with an end of first retracting spring 6 through first spring dead plate 4, and the other end of first retracting spring is connected with movable block chute 13 through second spring dead plate 7; Punch retainer 5 contacts through the inclined-plane with movable block chute 13 and produces sliding friction pair, thereby slides up and down along the inclined-plane.

Another end wall of movable block chute 13 is provided with backhaul limited block 8, and this backhaul limited block is corresponding with the end of movable block 10/contact.

Flange die 1 is the eccentric swage dual-purpose of this pair mould; Be installed on the upper bolster through breaker bolt; Wedge slide block 9 is fixed on the upper bolster 15 through screw; Flange die 1 is fixed on the movable block chute 13 through screw, and flanging die 3 is fixed on punch retainer 5 and together is placed in the flange holding pad 2, cooperates with movable block 10 and can slide up and down on the inclined-plane with its motion; First retracting spring 6 is separately fixed on flanging die fixed head 5 and the movable block chute 13 through first spring dead plate 4, second spring dead plate 7; Second retracting spring 12 is fixed on the movable block 10 through the 3rd spring dead plate 11, and movable block 10 is placed in the movable block chute 13, and movable block chute 13 is through being bolted on the die shoe 14.

When upper bolster moves downward; Flange die 1 (eccentric swage) contact plate earlier also lets the flange holding pad push down plate gradually, and the while patrix drives wedge slide plate 9 and moves down with certain angle along the guide plate that is fixed in upper bolster, and this moment, guide pillar also moved downwards in guide pin bushing; After movable block 10 contacts; Drive it and move backward, cause the flanging die fixed head on its inclined-plane, to slide, flanging die is accomplished outward flanging along certain angle; The patrix backhaul, second retracting spring 12 that is in compressive state orders about movable block 10 backhauls, accomplishes whole outward flanging process.Simultaneously, first retracting spring 6 that is in elongated condition orders about the flanging die backhaul, prevents to get to expect to get stuck phenomenon.
